THREE CHANNELS OF ALL DIFFERENT SIZES
`Figures lO0A-100D are schematic representations of digital camera apparatus 300 in
`
`accordance with further embodiments of the present invention. In each of these embodiments,
`
`the digital camera apparatus include three or more camera channels, e.g., camera channels 350A-
`
`5
`
`350C. A first one of the camera channels, e.g., camera channel 350A, is smaller in size than a
`
`second one of the camera channels, e.g., camera channel 350B, which is in turn smaller in size
`
`than a third one of the camera channels, e.g., camera channel 350C.
`
`Referring to Figures 101A-101G, in some embodiments, the smallest camera channels,
`
`e.g., camera channels 350A, has a resolution that is smaller than the resolution of the second
`
`10
`
`camera channel, e.g., camera channel 350B, which has a resolution that is smaller than the
`
`resolution of the largest camera channel, e.g., camera channel 350C. For example, the smallest
`
`camera channels, e.g., camera channel 350A, may have a sensor array with fewer pixels than is
`
`provided in the sensor array of the second camera channel, e.g., camera channel 350B, for a
`
`comparable portion of the field of view, and the second camera channel, e.g., camera channel
`
`15
`
`350B, may have a sensor array with fewer pixels than is provided in the sensor array of the
`
`largest camera channel, e.g., camera channel 350C, for a comparable portion of the field of view.
`In one embodiment, for example, the number of pixels in the second camera channel, e.g.,
`camera channel 350B, is forty four percent greater than the number of pixels in the smallest
`
`camera channel, e.g., camera channel 350A, for a comparable portion of the field of view, and
`
`20
`
`the number of pixels in the largest camera channel, e.g., camera channel 350C, is thirty six
`
`percent greater than the number of pixels in the second camera channel, e.g., camera channel
`
`350B, for a comparable portion of the field of view. It should be understood, however, that any
`
`other sizes and/or architectures may also be employed.
`
`Referring to Figures 102A-102G, in some other embodiments, one or more of the smaller
`
`25
`
`camera channels, e.g., camera channels 350A-350B, has a resolution that is equal to the
`
`resolution of the larger camera channel, e.g., camera channel 350C. For example, one or more of
`
`the smaller camera channels, e.g., camera channels 350A-350B, may have a sensor array with
`
`the same number of pixels as is provided in the sensor array of the larger camera channel, e.g.,
`
`camera channel 350C, for a comparable portion of the field of view.
`
`30
`
`In one embodiment, for example, the pixels in the second camera channel, e.g., camera
`
`channel 350B, are forty four percent larger in size (e.g., twenty percent larger in the x direction
`
`and twenty percent larger in the y direction) than the pixels in the smallest camera channel, e.g.,
`Page 126
`
`Ex.1030 / Page 911 of 1435
`TESLA, INC.
`
`

`

`camera channel 350A. In another embodiment, for example, the pixels in the largest camera
`
`channel, e.g., camera channel 350C, are thirty six percent larger in size (e.g., seventeen percent
`
`larger in the x direction and seventeen percent larger in the y direction) than the pixels in the
`
`second camera channel, e.g., camera channel 350B. It should be understood, however, that any
`
`5
`
`other sizes and/or architectures may also be employed.
`
`In some embodiments, the first camera channel, e.g., camera channel 350A, is dedicated
`
`to a first color or first band of colors (e.g., red or a red band of colors), the second camera
`
`channel, e.g., camera channel 350B, is dedicated to second color or second band of colors (e.g.,
`
`blue or a blue band of colors), different than the first color or first band of colors, and the third
`
`10
`
`camera channel, e.g., camera channel 350C, is dedicated to third color or third band of colors
`
`(e.g., green or a green band of colors), different than the first and second colors or band of
`
`colors. In some of such embodiments, the two smaller camera channels, e.g., camera channels
`
`350A-350B, each have a lower resolution than the third camera channel, e.g., camera channel
`
`350C. In some other embodiments, each of the camera channels, e.g., camera channels 350A-
`
`15
`
`350C, has the same resolution.
`
`In some embodiments, the number of pixels and/or the design of the pixels in the sensor
`
`array of a camera channel are adapted to match a wavelength or band of wavelengths of incident
`
`light to which such camera channels may be dedicated.
`
`In some embodiments, the size of the sensor array and/or the design of the optics (e.g., f/#
`
`20
`
`and focal length) for one or more of the camera channels are adapted to provide a desired field of
`
`view and/or sensitivity for such camera channels.
`
`In some embodiments, one of the camera channels is a broadband camera channel, an
`
`infrared (IR) camera channel or an ultraviolet (UV) camera channel.
`
`In some embodiments, one or more of the camera channels are dedicated to a wavelength
`
`25
`
`or band of wavelengths and the sensor array and/or optics portion of such one or more camera
`
`channels are optimized for the respective wavelength or band of wavelengths to which the
`
`respective camera channel is dedicated. In some embodiments, the design, operation, array size
`
`and/or pixel size of each sensor array is optimized for the respective wavelength or bands of
`
`wavelengths to which the camera channels are dedicated. In some embodiments the design of
`
`30
`
`each optical portion is optimized for the respective wavelength or bands of wavelengths to which
`
`the respective camera channel is dedicated.

`

`

`In some embodiments, the digital camera apparatus employs a processor that is disposed
`
`on the same integrated circuit as the sensor arrays. The processor may have any layout,
`
`including for example, a layout that is the same as, or similar to, the layouts described herein (see
`
`for example, Figures 100B-100D. In some embodiments, the processor may have one or more
`
`5
`
`portions that are not disposed on the same integrated circuit as the sensor arrays and/or may not
`
`have any portions disposed on the same integrated circuit as the sensor arrays (see for example,
`
`Figures 1 O0A).
`
`As stated above, each of the embodiments described above may be used alone or in
`
`combination with any other embodiment(s) or portion thereof described herein or known to those
`
`10
`
`of ordinary skill in the art.
`
`In some embodiments, the camera channels, e.g., camera channels 350A-350C, are
`
`connected via one or more communication links to one or more displays.
`
`In some such
`
`embodiments, each of the camera channels is connected to its own display. The displays may or
`
`may not have the same characteristics. For example, in some embodiments, one or more of the
`
`15
`
`camera channels have a resolution that is less than the resolution of one or more other camera
`
`channels and the one or more display connected to the one or more lower resolution camera
`
`channels may have a resolution/resolutions that is/are lower than the resolution/resolutions of the
`
`one or more displays connected to the one or more other camera channels.
`
`THREE ELLIPTICAL CHANNELS OF ALL DIFFERENT SIZES
`
`20
`
`Figures 103A-103E are schematic representations of digital camera apparatus 300 in
`
`accordance with further embodiments of the present invention. In each of these embodiments,
`
`the digital camera apparatus include one or more camera channels, e.g., camera channels 350A-
`
`350C, having an optical portion, e.g., optical portions 330A-330C, respectively, with an elliptical
`
`or other type of non circular shape.
`
`25
`
`In some embodiments, one or more of the camera channels, e.g., camera channels 350A-
`
`350B, are smaller in size than a third camera channel, e.g., camera channel 350C. In some of
`
`such embodiments, the one or more smaller camera channels, e.g., camera channels 350A-350B,
`
`may each have a resolution that is less than the resolution of the larger camera channel, e.g.,
`
`camera channel 350C, although in such embodiments, the smaller camera channels may or may
`
`30
`
`not have the same resolution as one another. For example, each of the smaller camera channels,
`
`e.g., camera channel 350A-350B, may have a sensor array with fewer pixels than is provided in
`
`Page 128
`
`Ex.1030 / Page 913 of 1435
`TESLA, INC.
`
`

`

`the sensor array of the larger camera channel, e.g., camera channel 350B, for a comparable
`portion of the field of view. In one embodiment, for example, the number of pixels in the larger
`
`camera channel is forty four percent greater than the number of pixels in one or more of the
`
`smaller camera channels, for a comparable portion of the field of view. In another embodiment,
`
`5
`
`for example, the number of pixels in the larger camera channel is thirty six percent greater than
`
`the number of pixels in one or more of the smaller camera channels, for a comparable portion of
`
`the field of view.
`
`It should be understood, however, that any other sizes and/or architectures
`
`may also be employed.
`
`If one or more of the camera channels, e.g., camera channels 350A-350B, are smaller in
`
`10
`
`size than a third camera channel, e.g., camera channel 350C, the one or more of the smaller
`
`camera channels, may have a resolution that is equal to the resolution of the larger camera
`
`channel. For example, one or more of the smaller camera channels, e.g., camera channels 350A-
`
`350B, may have a sensor array with the same number of pixels as is provided in the sensor array
`
`of the larger camera channel, e.g., camera channel 350C, for a comparable portion of the field of
`
`15
`
`view. In one embodiment, for example, the pixels in the larger camera channel are forty four
`
`percent larger in size ( e.g., twenty percent larger in the x direction and twenty percent larger in
`
`the y direction) than the pixels in the smaller camera channels.
`
`In another embodiment, for
`
`example, the pixels in the larger camera channel are thirty six percent larger in size ( e.g.,
`
`seventeen percent larger in the x direction and seventeen percent larger in the y direction) than
`
`20
`
`the pixels in the smaller camera channels. It should be understood, however, that any other sizes
`
`and/or architectures may also be employed.
`
`In some embodiments, the first camera channel, e.g., camera channel 350A, is dedicated
`
`to a first color or first band of colors (e.g., red or a red band of colors), the second camera
`
`channel, e.g., camera channel 350B, is dedicated to second color or second band of colors (e.g.,
`
`25
`
`blue or a blue band of colors), different than the first color or first band of colors, and the third
`
`camera channel, e.g., camera channel 350C, is dedicated to third color or third band of colors
`
`(e.g., green or a green band of colors), different than the first and second colors or band of
`
`colors. In some of such embodiments, the two smaller camera channels, e.g., camera channels
`
`350A-350B, each have a lower resolution than the third camera channel, e.g., camera channel
`
`30
`
`350C.
`
`In some embodiments, one of the camera channels is a broadband camera channel, an
`
`infrared (IR) camera channel or an ultraviolet (UV) camera channel.

`

`

`In some embodiments, the digital camera apparatus employs a processor that is disposed
`
`on the same integrated circuit as the sensor arrays. The processor may have any layout,
`
`including for example, a layout that is the same as, or similar to, the layouts described herein (see
`
`for example, Figures 103B-103E). In some embodiments, the processor may have one or more
`
`5
`
`portions that are not disposed on the same integrated circuit as the sensor arrays and/or may not
`
`have any portions disposed on the same integrated circuit as the sensor arrays (see for example,
`
`Figure 103A).
`
`As stated above, each of the embodiments described above may be used alone or in
`
`combination with any other embodiment(s) or portion thereof described herein or known to those
`
`10
`
`of ordinary skill in the art.
`
`In some embodiments, one or more of the camera channels, e.g., camera channels 350A-
`
`350C, are connected via one or more communication links to one or more displays. In some
`
`such embodiments, each of the camera channels is connected to its own display. The displays
`
`may or may not have the same characteristics as one another. For example, if the camera
`
`15
`
`channels have different resolutions from one another, the displays may also have different
`
`resolutions from one another. For example, in some embodiments, the smaller channels, e.g.,
`
`camera channels 350A-350B, have a resolution that is less than the resolution of the larger
`
`channel, e.g., camera channel 350B, and the displays connected to the smaller channels have
`
`resolution that is less than the resolution of the display connected to the larger camera channel.
`
`20
`
`In some other embodiments, the two smaller camera channels, e.g., camera channels 350A-350B,
`
`are connected to a first display and the larger camera channel, e.g., camera channel 350C is
`
`connected to a second display. The first and second displays may or may not have the same
`
`characteristics as one another. For example, in some embodiments, the smaller channels, e.g.,
`
`camera channels 350A-350B, have a resolution that is less than the resolution of the larger
`
`25
`
`channel, e.g., camera channel 350B, and the display connected to the smaller channels has a
`
`resolution that is less than the resolution of the display connected to the larger camera channel.
`
`TWO CAMERA CHANNELS
`
`Figures 104A-104E are schematic representations of digital camera apparatus 300 in
`
`accordance with further embodiments of the present invention. In each of these embodiments,
`
`30
`
`the digital camera apparatus include two or more camera channels, e.g., camera channels 350A-
`
`350B.
`
`Page 130
`
`Ex.1030 / Page 915 of 1435
`TESLA, INC.
`
`

`

`In some embodiments, the first camera channel, e.g., camera channel 350A, is dedicated
`
`to a single color or a single band of colors (e.g., red or a red band) and the second camera
`
`channel, e.g., camera channel 350B, is dedicated to a single color or single band of colors (e.g.,
`
`green or a green band), different from the color or band of colors to which the first camera
`
`5
`
`channel is dedicated. In some embodiments, one or more of the camera channels employs a
`
`pixel size that matches the color optical blur for the respective camera channel, an integration
`
`time and/or other electrical characteristic of the sensor array adapted to increase or optimize
`
`performance of the respective camera channel, and/or a design/layout of the pixel circuitry and
`
`photodiode that is adapted to increase or maximize sensitivity of the respective camera channel.
`
`10
`
`In some embodiments, one of the camera channels is a broadband camera channel, an
`
`infrared (IR) camera channel or an ultraviolet (UV) camera channel.
`
`In some other embodiments, the first camera channel, e.g., camera channel 350A, is
`
`dedicated to two or more separate colors or two or more separate bands of colors (e.g., blue or a
`
`blue band and red or a red band). In some of such embodiments, the optical portion may itself
`
`15
`
`have the capability to provide color separation, for example, similar to that provided by a color
`
`filter array ( e.g., a Bayer pattern or variation thereof). In some embodiments, the lens and/or
`
`filter of the camera channel may transmit both of such colors or bands of colors and the camera
`
`channel may include one or mechanisms elsewhere in the camera channel to separate the two
`
`colors or two bands of colors. For example, a color filter array may be disposed between the lens
`
`20
`
`and the sensor array and/or the camera channel may employ a sensor capable of separating the
`
`colors or bands of colors. In some of the latter embodiments, the sensor array may be provided
`
`with pixels that have multiband capability, e.g., two or three colors. For example, each pixel
`
`may comprise two or three photodiodes, wherein a first photodiode is adapted to detect a first
`
`color or first band of colors, a second photodiode is adapted to detect a second color or band of
`
`25
`
`colors and a third photodiode is adapted to detect a third color or band of colors. One way to
`
`accomplish this is to provide the photodiodes with different structures/characteristics that make
`
`them selective, such that first photodiode has a higher sensitivity to the first color or first band of
`
`colors than to the second color or band of colors, and the second photodiode has a higher
`
`sensitivity to the second color or second band of colors than to the first color or first band of
`
`30
`
`colors. Another way is to dispose the photodiodes at different depths in the pixel, which takes
`
`advantage of the different penetration and absorption characteristics of the different colors or
`
`bands of colors. For example, blue and blue bands of colors penetrate less (and are thus
`Page 131
`
`Ex.1030 / Page 916 of 1435
`TESLA, INC.
`
`

`

`absorbed at a lesser depth) than green and green bands of colors, which in turn penetrate less
`
`(and are thus absorbed at a lesser depth) than red and red bands of colors. In some embodiments,
`
`such a sensor array is employed even though the pixels may see only one particular color or band
`
`of colors, for example, to in order to adapt such sensor array to the particular color or band of
`
`5
`
`colors.
`
`In some of the latter embodiments, the second camera channel, e.g., camera channel
`
`350B, is dedicated to a single color or a single band of colors ( e.g., green or a green band),
`
`different from the colors or band of colors to which the first camera channel is dedicated. In
`
`some other embodiments, the second camera channel, e.g., camera channel 350B, is also
`
`IO
`
`dedicated to two or more separate colors or two or more separate bands of colors. For example,
`
`the first camera channel may be dedicated to red or a red band and green or a green band (e.g.,
`
`G 1 ). The second camera channel may be dedicated to blue or a blue band and green or a green
`
`band (e.g., 02).
`
`The two or more camera channels may or may not have the same configuration (e.g.,
`
`15
`
`size, shape, resolution, or degree or range of sensitivity) as one another. In some embodiments,
`
`for example, each of the camera channels has the same size, shape, resolution and/or degree or
`
`range of sensitivity as one another. In some other embodiments, one or more of the camera
`
`channels has a size, shape, resolution and/or a degree or range of sensitivity that is different than
`
`one or more of the other camera channels. For example, one or more of the camera channels
`
`20 may have a sensor array with fewer pixels than is provided in the sensor array of one or more of
`
`the other camera channels, for a comparable portion of the field of view.
`
`In some embodiments, one of the camera channels may have a sensor array with a size
`
`that is different than the size of the sensor array of the other camera channels. In some of such
`
`embodiments, the optics portion of such one or more camera channels may have a f/# and/or a
`
`25
`
`focal length that is different from the fl# and/or a focal length of the one or more of the other
`
`camera channels.
`
`In some embodiments, one or more of the camera channels are dedicated to a wavelength
`
`or band of wavelengths and the sensor array and/or optics portion of such one or more camera
`
`channels are optimized for the respective wavelength or band of wavelengths to which the
`
`30
`
`respective camera channel is dedicated. In some embodiments, the design, operation, array size
`
`and/or pixel size of each sensor array is optimized for the respective wavelength or bands of
`
`wavelengths to which the camera channels are dedicated. In some embodiments the design of
`Page 132
`
`Ex.1030 / Page 917 of 1435
`TESLA, INC.
`
`

`

`each optical portion is optimized for the respective wavelength or bands of wavelengths to which
`
`the respective camera channel is dedicated.
`It should be understood however, that any other configurations may be employed.
`
`The two or more camera may be arranged in any manner. In some embodiments, the two
`
`5
`
`or more camera channels are arranged in linear array, as shown.
`
`In some embodiments, the digital camera apparatus employs a processor that is disposed
`
`on the same integrated circuit as the sensor arrays. The processor may have any layout,
`
`including for example, a layout that is the same as, or similar to, the layouts described herein (see
`
`for example, 104C-104E). In some embodiments, the processor may have one or more portions
`
`10
`
`that are not disposed on the same integrated circuit as the sensor arrays and/or may not have any
`
`portions integrated in or disposed on the same integrated circuit as the sensor arrays (see for
`
`example, Figures 104B).
`
`As stated above, each of the embodiments described above may be used alone or in
`
`combination with any other embodiment(s) or portion thereof described herein or known to those
`
`15
`
`of ordinary skill in the art.
`
`In some embodiments, one or more of the camera channels, e.g., camera channels 350A-
`
`350B, are connected via one or more communication links to one or more displays. In some
`
`such embodiments, each of the camera channels is connected to a separate display, i.e., the
`
`smaller camera channel, e.g., camera channel 350A, is connected to a first display and the larger
`
`20
`
`camera channel, e.g., camera channel 350B, is connected to a second display. The first and
`
`second displays may or may not have the same characteristics. In some embodiments, the first
`
`display has a resolution equal to the resolution of the camera channel connected thereto. The
`
`second display may have a resolution equal to the resolution of the camera channels connected
`
`thereto, however, other resolutions may be employed. Other resolutions may also be employed.

`
`TWO CHANNELS, ONE SMALLER THAN OTHER
`
`Figures 105A-105E are schematic representations of digital camera apparatus 300 in
`
`accordance with further embodiments of the present invention. In each of these embodiments,
`
`the digital camera apparatus include two or more camera channels, e.g., camera channels 350A-
`
`350B. A first one of the camera channels, e.g., camera channel 350A, is smaller in size than a
`
`30
`
`second one of the camera channel, e.g., camera channel 350B.
`
`Page 133
`

`
`

`

`In some embodiments, the smaller camera channel, e.g., camera channel 350A, has
`
`resolution that is less than the resolution of the larger camera channel, e.g., camera channel
`
`350B. For example, the smaller camera channel, e.g., camera channel 350A, may have a sensor
`
`array with fewer pixels than the sensor array of the larger camera channel, e.g., camera channel
`
`5
`
`350B, for a comparable portion of the field of view.
`
`In one embodiment, for example, the
`
`number of pixels in the larger camera channel is forty four percent greater than the number of
`
`pixels in the smaller camera channel, for a comparable portion of the field of view. In another
`
`embodiment, for example, the number of pixels in the larger camera channel is thirty six percent
`
`10
`
`greater than the number of pixels in the smaller camera channel, for a comparable portion of the
`field of view. It should be understood, however, that any other sizes and/or architectures may
`also be employed.
`
`In some other embodiments, the smaller camera channel, e.g., camera channel 350A, has
`
`a resolution that is equal to the resolution of the larger camera channel, e.g., camera channel
`
`350B. For example, the smaller camera channel, e.g., camera channel 350A, may have a sensor
`
`15
`
`array with pixels that are equal in number but smaller than the pixels of the sensor array of the
`
`larger camera channel, e.g., camera channel 350B, for a comparable portion of the field of view.
`
`In one embodiment, for example, the pixels in the larger camera channel are forty four percent
`
`larger in size ( e.g., twenty percent larger in the x direction and twenty percent larger in the y
`
`direction) than the pixels in the smaller camera channel. In another embodiment, for example,
`
`20
`
`the pixels in the larger camera channel are thirty six percent larger in size ( e.g., seventeen
`
`percent larger in the x direction and seventeen percent larger in they direction) than the pixels in
`
`the smaller camera channel.
`
`It should be understood, however, that any other sizes and/or
`
`architectures may also be employed.
`
`In some embodiments, one of the camera channels is a broadband camera channel, an
`
`25
`
`infrared (IR) camera channel or an ultraviolet (UV) camera channel.
`
`In some embodiments, the first camera channel, i.e., the smaller camera channel, is
`
`dedicated to a single color or a single band of colors (e.g., red or a red band) and the second
`
`camera channel, i.e., the larger camera channel, is dedicated to a single color or single band of
`
`colors (e.g., green or a green band), different from the color or band of colors to which the first
`
`30
`
`camera channel is dedicated.
`
`In some other embodiments, one of the camera channels, e.g., the smaller camera
`
`channel, is dedicated to two or more separate colors or two or more separate bands of colors
`Page 134
`
`Ex.1030 / Page 919 of 1435
`TESLA, INC.
`
`

`

`(e.g., blue or a blue band and red or a red band). In some of such embodiments, the lens and/or
`
`filter of the camera channel may transmit both of such colors or bands of colors and the camera
`
`channel may include one or mechanisms elsewhere in the camera channel to separate the two
`
`colors or two bands of colors. For example, a color filter array may be disposed between the lens
`
`5
`
`and the sensor array and/or the camera channel may employ a sensor capable of separating the
`
`colors or bands of colors. In some of the latter embodiments, the sensor may be provided with
`
`sensor elements or pixels that each comprise two photodiodes, wherein the first photodiode is
`
`adapted to detect the a first color or first band of colors and the second photodiode is adapted to
`
`detect the second color or band of colors. One way to accomplish this is to provide the
`
`10
`
`photodiodes with different structures/characteristics that make them selective, such that first
`
`photodiode has a higher sensitivity to the first color or first band of colors than to the second
`
`color or band of colors, and the second photodiode has a higher sensitivity to the second color or
`
`second band of colors than to the first color or first band of colors. Another way is to dispose the
`
`photodiodes at different depths in the pixel, which takes advantage of the different penetration
`
`15
`
`and absorption characteristics of the different colors or bands of colors. For example, blue and
`
`blue bands of colors penetrate less (and are thus absorbed at a lesser depth) than green and green
`
`bands of colors, which in turn penetrate less (and are thus absorbed at a lesser depth) than red
`
`and red bands of colors.
`
`In some embodiments, the digital camera apparatus employs a processor that is disposed
`
`20
`
`on the same integrated circuit as the sensor arrays. The processor may have any layout,
`
`including for example, a layout that is the same as, or similar to, the layouts described herein (see
`
`for example, 1 0SC-1 0SE). In some embodiments, the processor may have one or more portions
`
`that are not disposed on the same integrated circuit as the sensor arrays and/or may not have any
`
`portions integrated in or disposed on the same integrated circuit as the sensor arrays (see for
`
`25
`
`example, Figures 105B). As stated above, each of the embodiments described above may be
`
`used alone or in combination with any other embodiment(s) or portion thereof described herein
`
`or known to those of ordinary skill in the art.
`
`To that effect, in some embodiments, the smaller camera channel is dedicated to two or
`
`more separate colors ( or two or more separate bands of colors) and in addition, has a resolution
`
`30
`
`that is less than the resolution of the larger camera channel.
`
`In some embodiments, the camera channels, e.g., camera channels 350A-350B, are
`
`connected via one or more communication links to one or more displays.

`
`

`

`embodiments, each of the camera channels is connected to a separate display, i.e., the smaller
`
`camera channel, e.g., camera channel 350A, is connected to a first display and the larger camera
`
`channel, e.g., camera channel 350B, is connected to a second display, different than the first
`
`display. The first and second displays may or may not have the same characteristics. In some
`
`5
`
`embodiments, the first display has a resolution equal to the resolution of the camera channel
`
`connected thereto. The second display may have a resolution equal to the resolution of the
`
`camera channels connected thereto, however, other resolutions may be employed.
`
`GROUP OF IMAGE SENSOR CHIPS
`
`Figures 106A-106C are schematic perspective views of a system having a plurality of
`
`10
`
`digital camera apparatus, e.g., two digital camera apparatus, in accordance with another
`
`embodiment of the present invention. The plurality of digital camera apparatus may be arranged
`
`in any desired manner. In some embodiments, it may be desired to collect images from opposing
`
`directions. In some embodiments, the digital camera apparatus are mounted back to back, as
`
`shown. Some of such embodiments may allow concurrent imaging in opposing directions.
`
`15
`
`In some embodiments, the one or more optics portions for the first camera subsystem
`
`face in a direction that is opposite to the direction that the one or more optics portions for the
`
`second digital camera apparatus face. In the illustrated embodiment, for example, the system has
`
`first and second sides generally opposite one another. A first one of the digital camera apparatus
`
`may be positioned to receive light through a first side of the digital camera apparatus. A second
`
`20
`
`one of the digital camera apparatus may be positioned to receive light through the second side of
`
`the system. Other configurations may also be employed.
`
`In some embodiments, each of the subsystems has its own sets of optics, filters and
`
`sensors arrays, and may or may not have the same applications and/or configurations as one
`
`another, for example, in some embodiments, one of the subsystems may be a color system and
`
`25
`
`the other may be a monochromatic system, one of the subsystems may have a first field of view
`
`and the other may have a separate field of view, one of the subsystems may provide video
`
`imaging and the other may provide still imaging.
`
`The plurality of digital camera subassemblies may have any size and shape and may or
`
`may not have the same configuration as one another (e.g., type, size, shape, resolution). In the
`
`30
`
`illustrated embodiment, one of the subsystems has a length and a width that are equal to the
`
`length and width, respectively of the other subsystem, although this is not required.

`

`

`In some embodiments, one or more sensor portions for the second digital camera
`
`apparatus are disposed on the same device (e.g., image device) as one or more sensor portions
`
`for the first digital camera apparatus. In some embodiments, one or more sensor portions for the
`
`second digital camera apparatus are disposed on a second device (e.g., a second image device),
`
`5 which may be disposed, for example, adjacent to the image device on which the one or more
`
`sensor portions for the first digital camera apparatus are disposed.
`
`In some embodiments, two or more of the digital camera apparatus share a processor, or a
`
`portion thereof. In some other embodiments, each of the digital camera apparatus has its own
`
`dedicated processor separate from the processor for the other digital camera apparatus.
`
`In some embodiments, the system defines a hermetic package, although this is not
`
`required.
`
`As with each of the embodiments disclosed herein, this embodiment of the present
`
`invention may be employed alone or in combination with one or more of the other embodiments
`
`disclosed herein, or portion thereof.
`
`15
`
`The digital camera apparatus may be assembled and/or mounted in any manner, for
`
`example, but not limited to in a manner similar to that employed in one or more of th
