`(54) Title of the Invention:
` Electronic Still Camera with Cellular Phone Function
`
`(57) [Abstract]
`[Purpose of the Invention] To improve instantaneity by equipping an electronic still camera with a cellular
`phone function and making the same immediately available to transmit a captured image to a large storage
`medium in another location via a telephone line. Additionally, to miniaturize the camera body by making a
`display, used to confirm the captured image, attachable and detachable.
`[Composition] A camera section is powered when half-pressing a release button (12) as a control circuit (25)
`regulates image recording. The subject image is exhibited on a display (8) via a lens (1), an imaging element (2), an
`image processing circuit (4), and a driver (7). When a composition is determined and the release button (12) pushed
`the image data is recorded to internal memory (26) while, at the same time, an image line securing means (24)
`executes a call request to a telephone number previously inputted to a control circuit (28) in the cellular phone
`function and instructs the same to connect to the line. The image data in internal memory (26) is read when the
`connection is made. The control circuit (28) delivers the image date to the line via a modulating circuit (29) and a
`transmitting circuit (21).

`[Detailed Explanation of the Invention]
`[0001]
`[Industrial Field of Application] The present invention concerns an electronic still camera equipped with a
`cellular phone that sends and receives call signals via radio waves.
`[0002]
`[Prior Art] Recent electronic still cameras have been digitized for stabilizing circuits and for related reasons.
`Memory cards have likewise been utilized to inhibit the degradation of images even in external storage media.
`Figure 10 is a circuit diagram illustrating one example of a prior digital electronic still camera. Light from an
`object not indicated in the drawing is imaged onto an image sensing element (2) via a lens (1). An A/D
`converter (3) converts output from the image sensing element (2) to a digital signal and an image processing
`circuit (4) implements a predetermined process. Image data from the image processing circuit (4) is then
`compressed and encoded. A decoding circuit (6) expands the encoded image data, which a driver (7) then
`displays on a display (8). Pressing a release button (12) sends the pressing information to a control circuit (11)
`and records the encoded image data to a memory card (10). When internal memory (9), for example the
`content of the memory card (10), is insufficient the captured image is temporarily stored, then used to save the
`captured image to a different memory card having free space.
`[0003]
`[Problems to Be Resolved by the Invention] The memory card is thus used as an external storage medium, but
`there are problems, including the number of images storable in the memory card being few and prices still
`quite high. Moreover, many of the finders used to monitor the recorded objects and to confirm the captured
`images in current cameras and videos employ liquid crystal displays for easy viewability. The demerit here is
`that using a liquid crystal display increases the feature size of the camera overall.
`[0004] Consequently, to serve as a means for resolving the above-noted drawbacks the present inventor
`proposes providing a cellular phone function to render photographibility without mounting a memory card.
`Figure 11 is a circuit diagram illustrating one example of a prior cellular phone function. A call is originated
`
`
`
`3
`
`Ex. GOOG 1025
`
`

`

`when a dial controller inputs an other-party telephone number; a control circuit (17) sends the inputted
`telephone number through a modulating circuit (18) to a transmitting circuit (21). The transmitting circuit (21)
`superimposes the imputed telephone number onto the carrier wave from a carrier wave synthesizer (20), then
`transmits it via a duplexer (22) and antenna (23). The call is enabled when a response is received that the
`connection has been made with the other party. Audio inputted from a mike (15) undergoes a prescribed
`modulation process via the modulating circuit (18) and is sent to the other party side through the transmitting
`circuit (21). Radio waves from the other party are received by a receiving circuit (19) via the antenna (23) and
`the duplexer (22). The receiving circuit (19) removes the carrier wave component and demodulates the audio
`signal via a demodulating circuit (16). The demodulated audio signal is regenerated by a speaker (13).
`[0005] The present invention is based upon the above considerations and has as its objective to provide an
`electronic still camera with cellular phone function that, equipping the electronic still camera with the cellular
`phone function, can improve instantaneity and follow up on the paucity of stored images in a memory card by
`configuring the device to allow the immediate transmitting of a captured image to a large storage medium in
`another location by using a telephone line. Another objective of this invention is to provide an electronic still
`camera with cellular phone function in an overall reduced size by making the display used to monitor the
`recorded objects and to confirm the captured images attachable to and detachable from the electronic still
`camera.
`[0006]
`[Means of Solving the Problems] To achieve the above objective the electronic still camera with cellular
`phone function based on the present invention is equipped with a digital electronic still camera having a lens,
`an image inputting means comprising an imaging element, an image encoding means, and an image storing
`means with a cellular phone function component that acts as a radio transceiver for phone call signaling;
`internal memory output from the image storing means is joined with modulating circuit input in the cellular
`phone function component; the electronic still camera is provided with a controlling means that turns off
`power to the camera component when, after pressing a release button, the camera component is powered up
`and an image from the image inputting means is stored to the internal memory of the image storing means, and
`is provided with an image line securing means regulating image data readout stored in the internal memory
`when, pressing the release button, a controlling means in the cellular phone function component is activated to
`simultaneously implement a call request, raising and sending out a previously determined other party telephone
`number, and make the connection; the cellular phone function component is provided with a controller that
`regulates reconnecting the line after a set amount of time in instances where, although the line is connected via
`control from the image line securing means and the image data from the internal memory is sent to the
`connected line, the transmission terminates, cutting off the line and breaking the connection. Furthermore, the
`present invention, to achieve the other objective, is provided with a driver and a display, and equipped with a
`memory card-type display having a terminal that is attachable to and detachable from an attaching section of
`the memory card relative to the image storing means, and a configuration that absorbs external light on the
`back side of the display; the display is used as a finder and a playback screen after connecting the same to the
`memory card attachable/detachable section.
`[0007]
`[Operation of the Invention] According to the above-noted configuration the power is turned on, an image of
`the object is recorded to internal memory, and the line used to transmit the image secured when the release
`button is pushed. The image is immediately transmitted when the line is secured and, when finished, the line
`cut off. Accordingly, the user can record an image without carrying around an expensive, low-capacity
`memory card or similar external storage medium, which resolves the above-noted problems. Additionally,
`rendering the display attachable allows for achieving miniaturizing the electronic still camera while enlarging
`only the component equipping the cellular phone function.

`

`[0008]
`[Working Example] The present invention will be explained in greater detail below with reference to the
`drawings. Figure 1 is a circuit diagram illustrating a working example of the electronic still camera with
`cellular phone function based on the present invention. In the drawing section A, enclosed within the dotted
`lines, is the functional section corresponding to the circuit component of the digital electronic still camera in
`Figure 10, and section B the functional section corresponding to the circuit component of the cellular phone
`function in Figure 11. The [illegible] to which same reference numerals are attached are parts fulfilling the
`same functions. The control circuit (25) for the digital electronic still camera supplies power to the camera
`section by half-pressing the release button (12), after which fully pressing the same implements controlling the
`accompanying image recording operation. When the image line securing means (24) acquires the pressing
`information from the release button (12) control information for implementing a call request from the cellular
`phone, dialing out, and connecting to the line is sent to a control circuit (28) in the cellular phone functional
`section. Line connection information is then acquired from the demodulating circuit (27) and an instruction to
`read the image data is issued to the internal memory (26) of the digital electronic still camera. An output
`terminal to the image data read from the internal memory (26) is connected to an input terminal to a
`modulating circuit (29) in the cellular phone functional section.
`[0009] Figure 2 is a diagram illustrating one example of an external view of the electronic still camera with
`cellular phone function based on the present invention. (a) shows an external perspective view of the camera,
`and (b) the state of a user holding the camera. A speaker (13) is positioned on the top front surface of the main
`unit (25), a mike (15) on the bottom front surface, and an antenna (23) and lens (1) provided on the top side.
`Positioned approximately in the center of the front surface is the display (8), beneath that a release button (12),
`and beneath that a dial (14). When recording an image the main unit is held in the right hand, as is indicated
`by (a), the lens (1) is directed towards an object not shown in the drawing, and the release button (12) is half
`pressed by a finger on the left hand, whereupon power is supplied to the camera section and the object image
`displayed on the display (8). The user determines the composition while viewing the display (8) then fully
`presses the release button (12) to record the image and transmit the same. When placing a phone call the user
`presses the transmitting button of the dial controller (14), as indicated by (a), then inputs the other party’s
`telephone number via the pushbutton pad, whereby the call can transpire via the speaker (13) and the mike (15).
`[0010] Figure 3 is a flow chart for explaining the operation of the electronic still camera with cellular phone
`function based on the present invention. Power is supplied to the camera section while the release button (12)
`is half depressed (Steps 1, 2) (henceforth “ST1, ST2”). The control circuit (25) converts the image of an object
`formed by the lens (1) onto the image sensing element (2) into a digital signal via the A/D converter (3), and
`the image processing circuit (4) implements an AGC (automatic gain control), γ-correction, or similar image
`process, after which it is displayed on the display (8) via the driver (7) (ST3, ST4). When the composition is
`determined and the release button (12) firmly pushed (ST5) the composition is encoded via the encoding
`circuit (5) and recorded to internal memory (ST6), leaving the circuit in a state preserving the requisite
`minimum in maintaining internal memory (26) in the circuit, then turning off the power supplied to the camera
`section (ST7). The control circuit (25) simultaneously determines whether or not the above actions are set to
`batch transmission mode (ST8), and when not set thereto gives and instruction to the image line securing
`means (24) to initiate a call to a control circuit (28) in the cellular phone function component (ST9). Batch
`transmission mode here refers to the mode by which a user transmits in a batch a predetermined number of
`images recorded and stored to internal memory. It is a mode the user can preset via a setting switch not shown
`in the drawing.
`[0011] The memory card (when attached) (10) and free space in internal memory (26) are checked (ST14)
`when batched transmission mode is set (14). Next, a determination is made concerning whether or not the free
`space is not greater than n number of images (n can be changed via the setting switch not shown in the
`
`
`
`5
`
`Ex. GOOG 1025
`
`

`

`drawing) (ST15). When the number of images exceeds n the process stops with no transmission. When the
`number of images is fewer than n the process reverts to ST9. The control circuit (28) reads from its own
`internal memory circuit the transmitted destination telephone number previously inputted by means of the
`pushbutton pad of the dial controller (14), sends it via a modulating circuit (29) and a transmitting circuit (21)
`(ST10), then monitors whether or not the circuit is connected (ST11). Next, when a signal is received from the
`line that the other party has responded the signal is received by a receiving circuit (19) and demodulated by a
`demodulating circuit (27), and the line connection information is inputted by means of the control circuit (28)
`and the image line securing means (24). The image line securing means (24) has the image data read from
`internal memory (26) by receiving this line connection information. The read image data is modulated by the
`modulating circuit (29), superimposed on the carrier wave by the transmitting circuit (21) and sent via the
`antenna (23) (ST12). When the transmission is terminated the control circuit (28) cuts off the line, then leaves
`the circuit with the necessary minimum power to remain in a call waiting mode and turns off the power (ST13).
`[0012] Without receiving a signal from the line that the other part has answered, when the line cannot be
`secured, a determination is made as to whether or not the other line is busy (including also when no reply is
`made) (ST16); if so a light will indicate that the other line is busy (ST17). When determined that the other
`party is not busy a light will indicate that one is in no position to send or receive radio waves (ST18). In
`neither case above are the lines connected, for which reason the control circuit (28), via the other control
`circuit (25), determines whether or not the memory card (10) is attached (ST19). The effect of this
`determination is that when the memory card (10) is not attached the user is alerted to this by the display or by
`audio (ST20). When the user acts in accord with the notice and inserts the memory card (10) (ST21), or has
`initially attached it, the image data recorded to internal memory (26) is transmitted to the memory card (10)
`(ST22). Whether or not the unit is set to retry mode is then checked (ST23). If the retry mode has not been set
`any operation for transmitting is thereupon terminated; but if the retry mode has been set the control circuit
`(28) activates a built in timer and turns off power to the other circuit section (ST24).
`[0013] Next, power is turned on for the other circuit section after the timer has run through a specified period
`of time, the call request is repeated, and the destination telephone number is read from internal memory (10).
`The read telephone number is sent to the line via the modulating circuit (29) and the transmitting circuit (21)
`(ST25). As a result of determining whether or not the line is securable (ST26) the image data is sent to internal
`memory (26) from the memory card (10) if the line can be connected (ST27). Additionally, the image data
`from internal memory (26) is sent to the line after passing through the modulating circuit (29) and the
`transmitting circuit (21) (ST12), and the transmission is terminated (ST13). Regardless of whether a call
`request is repeated when a line connection cannot be made ST24 is reverted to, the internal timer is activated,
`and, after a predetermined period of time, the operation placing a call request is again repeated.
`[0014] In the flow chart comprising Figure 3 it is assumed that the release button (12) has a separate power
`switch provided, and that by turning on this power switch the cellular phone function component is placed in a
`standby mode. A display section for the phone function component is not expressly provided, but one can
`double as a display (8). The retry mode, like the batch transmission mode, can be selected and operated by the
`setting switch not shown in the drawing. The retry mode is formatted so that if it is not connected at the first
`call origination the next one, for instance, will be placed after three minutes, and if after that a connection has
`not been made, the next attempt will be prolonged to occur after five minutes. Moreover, the image data is
`sent through the line by the aforementioned action sequence, but as a matter of course an image, when not
`transmitted, can be stored on the memory card after it is first recorded.
`[0015] Besides sending image data the same can be received from another location by providing a decoder.
`Additionally, line control of the storage media can be configured so that when a user desires to reference
`previously sent image data the user can control the storage medium of the other party through the transmission
`channel and have the image data sent therefrom. During a call photographs and images can be transmitted by a
`
`
`
`6
`
`Ex. GOOG 1025
`
`

`

`configuration employing two lines. Digitalizing the line allows for transmitting through a single line audio
`information and image information that has been bundled as a packet communication. Moreover, in recording
`an image there are sufficient instances where only black and white tones are used employing binary color data,
`such as when using textural information, and in such instances each circuit can be configured to allow for
`photographing, image processing, and encoding. When a self-timer is used for other functions line sections
`can be provided that alert the user by audio to the time remaining for recording an image, and add on and send
`information concerning the shooting location and environment via receiving data from a GPS position
`information acquiring means.
`[0016] Figure 4 comprises drawings for explaining another example of the external view of the electronic still
`camera with cellular phone function based on the present invention with (a) being an external oblique view of
`the same. The installation positions of the lens, finder, and release button differ from those in the external
`view of the camera body in Figure 2. The lens (30) is provided in a popup format on the left side surface. The
`finder (32) is provided in the same popup format on the right side surface. When the electronic still camera is
`not in use both the lens (30) and the finder (32) are housed inside the main unit. The release button (31) is
`provided below the finder (32) on the right side surface. (b) is a detail view of the finder (32) showing light is
`absorbed from the external incidence part (32a) and omitting a backlight for the liquid crystal display (32b).
`(c) and (d) indicate that the electronic still camera is grasped when in use, the left hand allowed to hold the
`main unit and the thumb on the right hand to press the release button (31), but it can be operated by one hand.
`With this configuration the base of the hand rests against a projecting part of the mike (15), making it easy to
`hold the sides and secure.
`[0017] Figure 5 comprises diagrams illustrating another working example of the electronic still camera with
`cellular phone function based on the present invention, (a) being an external oblique view and (b) an oblique
`view showing the status of the unit when in use. The present working example illustrates miniaturizing the
`electronic still camera, which tends to be large, by mounting a cellular phone function, and configuring it to
`allow for connecting a memory card-type display (34) to the memory card mounting section (10a) (see Figure
`1) in place of the memory card. (a) illustrates attaching the memory card-type display (34) to the memory card
`mounting section (10a) provided on the main unit top side front section while a mirror (41) is opened to serve
`as an external light absorbing part. A speaker (50) is positioned in the upper part of the main unit surface, a
`release button (45) therebeneath, and a dial controller (44) yet further therebeneath. A mike (46) is pivotally
`provided to the terminal part of the main unit surface and, when used, opened out as shown in (a), while when
`not used housed folded over the dial controller (44) and the release button (45). In this working example
`image data recorded to internal memory cannot be sent to the memory card when the line is disconnected.
`Accordingly, the memory card-type display (34) attached to the memory card mounting section (10) is opened
`out and the memory card mounted.
`[0018] Figure 6 is a circuit configuration diagram for the working example of Figure 5, a circuit drawing in
`which only the circuitry section differing from that in Figure 1 is excerpted and shown. The present circuit
`omits the display (8) and driver (7) in the circuit in Figure 1 but inserts a selecting circuit (43) between the
`encoding circuit (5) and the memory card mounting section (10a), which is configured to select output from
`the image processing circuit (4) or output from the encoding circuit (5) based on information from the card
`identification pin discussed below. Output from the encoding circuit (5) is connected when the memory card is
`attached, and output from the image processing circuit (4) is connected when the memory card-type display
`(34) is attached. Figure 7 is an oblique view for explaining the structure of the memory card-type display in
`Figure 5. The memory card mounting section turns into a pop-up connecter (49) which, when not in use, is
`housed inside the main unit, but when in use springs up appearing from part of the upper surface. The memory
`card-type display (34) can be inserted at an angle like that that shown in Figure 5(a). Figure 8(a) illustrates the
`circuit structure of the memory card-type display (34) in Figure 5. A terminal to the memory card connecter
`
`
`
`7
`
`Ex. GOOG 1025
`
`

`

`(40) is connected to a controller (39), and this controller (39) runs and regulates an X-driver (37) and a Y-
`driver (38). External light is incident on the back side of the LCD (36) passing from the mirror plate (41)
`through a diffusing panel (35). Figure 8(b) is an external oblique view of the memory card-type display.
`[0019] Figure 9 is an oblique view to explain the structure of the memory card-type display (34) in Figure 5.
`(a) is a drawing illustrating the deployed state of the mirror plate (41), and (b) is a drawing illustrating the
`structure of the liquid crystal section. A protective panel (51) is positioned over the LCD (36), and the
`diffusing panel (35) therebelow. The card identification pin (42) is provided to the edge of the joining terminal
`section, as shown in (c). The main unit can recognize that the memory card-type display (34) is attached via
`this card identification pin (42) and can switch over via the selecting circuit (43). Thus the display can be
`made smaller by rendering it attachable and detachable, power can be conserved, and if the memory card-type
`display should be damaged it can easily be replaced.
`[0020]
`[Effects of the Invention] As explained above, the present invention is configured so that a transmission call
`line is secured while an image is being recorded and the captured image data sent, for which reason images can
`be recorded with little concern over the number thereof or used memory capacity. Additionally, it is no longer
`necessary to carry a memory card about as an external storage medium. Accordingly, it is no longer even
`remotely necessary to carry around a memory card that can only store a few images and is expensive. The user
`can take photographs with a sense of using a remote control, because the captured image data is transmitted
`and the configuration of the unit is not like that of a camera. Moreover, power is applied to the camera section
`only when a photograph is taken and cut off when terminated, and because the power is automatically dropped
`when a line cannot be secured the use of wasted energy can be curbed and the unit used over relatively long
`periods of time. Again, when configured to substitute the memory card with a memory card-type display that
`can be attached to or detached from a memory card mounting section the memory card-type display can be
`removed when the camera is not in use. Consequently, miniaturization of the main body can be realized and
`the display itself can easily be replaced should it be damaged. Power is also conserved because external light
`is incident from the back side of the display.
