`
`
`“thinned” for display on an LCD screen by only reading, for example, every eighth pixel. Sato expressly states
`that this is done in both the horizontal and vertical directions. Thus, Sato expressly teaches that N may be up to
`8 times M, which is greater than 3M.
`
`
`When the image signal, stored in the frame memory 14, is read therefrom and then stored in
`the video memory 18 (see FIG. 1), some pixel signals are thinned or disregarded from the
`image signal, in accordance with the inherent resolution of the LCD 24, except when the
`inherent resolution has a value greater than a predetermined value. In the context of this
`specification, “thinning” is a process of reading only every [thinning number +1]th pixel,
`i.e., the thinning number is the number of skipped or disregarded pixels (per pixel read).
`The number of thinned pixels becomes greater as the inherent resolution becomes lower.
`Namely, in the case of the LCD 24 being of type D (160×120 pixels), pixel signals are only
`stored in the video memory 18 on every eighth pixel (i.e. an eight pixel separation in both
`the horizontal and vertical directions of the image), so that an image having a satisfactory
`number of pixels, which conforms to the inherent resolution of the LCD 24, is generated,
`and subsequently indicated by the LCD 24, while the expanded image data, stored in the
`frame memory 14, maintains the resolution of the original image signal, i.e., in this case,
`1280×960 pixels. The reason is as follows: Since the inherent resolution of the LCD 24 is
`160 ×120 pixels, only ⅛ of the pixels in both the horizontal direction and the vertical
`direction of the original 1280×960 pixel image (FIG. 2, F1) can be indicated by the LCD 24.

`Initially, the encoded image data of Scan (1), which are obtained by encoding the quantized
`DCT coefficients of the degrees 1 through 6, are read from the memory card 16. Then, the
`image data corresponding to Scan (1) are expanded, and stored in the frame memory 14.
`The expanded image data, for each of the blocks, are successively read from the frame
`memory 14, and are processed by the image processing circuit 13 to reproduce an image
`signal, thus enabling an image, which has a lower resolution as shown in FIG. 8, to be
`indicated on the LCD 24

`
` PHOSITA would have found it obvious to modify QV8000SX’s multimode camera to operate using the
`resolution-altering details taught by Sato for the advantage of reducing unnecessary processor load, thereby
`improving similar devices in the same way. Such a combination of prior art elements according to known
`methods would have yielded predictable results with a reasonable expectation of success.
`
`Alternatively, Horii discloses the limitations of claim 1(a)(ii). Horii discloses downscaling from a 1536x988
`resolution to a 768x494 resolution and then generating a video signal for the NTSC system.
`
`
`The image taking sensor 10 is a solid-state image sensing device, such as CCD, and has a
`number of effective pixels of 1536x988, which is large enough to provide high resolution.
`This image taking sensor is a single-plate color sensor in which a complementary color
`mosaic filter (Cy, Mg, Ye, Gr) is attached to a chip. FIG. 2 shows an example of the layout
`of the complementary color mosaic filter (Cy, Mg, Ye, Gr) attached to the chip. In the image
`taking sensor 10, the switch 9 effects switching between synchronous signals having different
`frequencies that are respectively generated by the first and second synchronous signal
`generators 7 and 8, thereby enabling the image taking sensor 10 to operate in two image
`taking modes.
`
`The second image taking mode will be explained first. The second synchronous signal
`generator 8 generates a synchronous signal for video signals (NTSC, PAL and the like).
`It effects thinning-out by reducing the apparent number of pixels through addition of pixels
`of the same filter arranged close to each other, or by skipping over part of the pixels when
`reading them from the image taking sensor 10. Alternatively, it reads only a particular
`storage area. In this way, it has the same access to data in the same way as in the case of
`video CCD, and reads 768x494 pixels in accordance with a video signal.
`
`
`

`
`
`Horii at 6:5-28.
`
`
`
` PHOSITA would reasonably understand that because (1) the original pixel size was 1536x988; and (2) the
`thinned 768x494 pixels are further interlaced in accordance with the NTSC system and the “frequency of the
`video signal,” then the pixel output is reduced by another ½ factor. Therefore, the resulting vertical pixel

`
`
`density is approximately 240 vertically arranged pixel lines or N=4M. See Horii at 1:12-23, 17:33-42; ’493
`Patent at 1:30-50 (describing the known NTSC system, which “performs interlaced scanning on two fields,
`each of which has an effective scanning line number of about 240 lines”), 4:64-5:6. This understanding of
`Horii’s teaching is consistent with the ’493 Patent’s disclosure that an image sensing device with 480 pixel
`rows has a standard effective number of vertically arranged pixels of 240 scanning lines in accordance with the
`NTSC system. ’493 Patent at 1:30-50, 4:64-5:6. Therefore, Horii’s teaching of reducing the 768x494 pixel
`density to be in accordance with the NTSC system further reduces the pixels by half to reach the effective 240
`scanning lines. See Horii at 17:33-47 (discussing reducing the pixels to 768x494 to be in the “same condition as
`in the case of a CCD sensor that is widely used in ordinary television sets is obtained” and with the further
`understanding that the pixels are subsequently interlaced for display on the television via the NTSC system). As
`such, Horii teaches N≥3M, where N=988 vertically arranged pixel lines and M=240 vertically arranged pixel
`lines to conform to transmission signals via the NTSC system.
`
`To the extent Plaintiff contends the claimed “effective scanning lines” equates to the resolution of the display
`screen, Horii discloses a display screen having M “effective scanning lines,” i.e., a resolution M of vertically
`arranged pixel lines under this interpretation, wherein N (=988) is equal to or greater than two times M.
`
`
`As in the first embodiment, the synchronous signal generated by the first or second
`synchronous signal generator 7 or 8 is switched by the switch 9 to drive the image taking
`sensor 10. The image signal taken by the image taking sensor 10 is subjected to sample-and-
`hold and AGC (automatic gain control) for removing switching noise and extracting the
`signal component at the SH,AGC circuit 13, and converted to digital data by the 10-bit A/D
`converter 14 to be stored in a third memory 38. Here, the third memory 38 has a capacity
`that is large enough to store both high-resolution image data (1536×988 pixels) read by the
`image taking sensor 10 in accordance with the first synchronous signal generator 7 and low-
`resolution image data (768×494 pixels) read by the image taking sensor 10 in accordance
`with the second synchronous signal generator 8.
`
`
`Horii at 7:30-44.
`
`
`
`
`Next, when previewing the image taken by the sensor 10, the image data stored in the first
`memory 215 is read under the control of the first memory controller 16 in accordance with
`the synchronous signal generated by the ordinary synchronous signal generator for

`
`television 8, and input to the second color processing section 31. Here, the image of
`1536×988 pixels is compressed to 1/2 and read as an image of 768×494 pixels. By thus
`reducing the number of pixels to 768×494, the same condition as in the case of a CCD
`sensor that is widely used in ordinary television sets is obtained.

`
`Horii at 17:33-42.
`
` A
`
` PHOSITA would have found it obvious to try any desirable factor of proportionality between the number of
`vertically arranged pixel lines N and the number of effective scanning lines M of the display screen. The choice
`of “three times” is a design choice that would have been trivial for a PHOSITA to modify, given the disclosure
`of Horii regarding the relationship between the image resolution and the displayed resolution. For example,
`Horii emphasizes reducing the pixel density in the normal mode to generate a video signal in accordance with
`the NTSC protocol or at a pixel density “that is widely used in ordinary television sets.” See Horii at 6:18-28,
`17:38-42, 20:21-26. Horii also teaches outputting the image taken in the normal mode “on a monitor without
`any portion thereof being lost.” Horii at 9:57-59.

` A
`
` PHOSITA would have found it obvious to modify QV8000SX’s multimode camera to operate using the
`resolution-altering details taught by Horii for the advantage of reducing unnecessary processor load, thereby
`improving similar devices in the same way. Additionally, QV8000SX expressly teaches that pictures recorded
`can be output to an attached TV screen in the NTSC format, further indicating to a PHOSITA the desirability of
`incorporating Horii’s pixel resolution details. QV8000SX Manual at 78, 87, 99, 119. Such a combination of
`prior art elements according to known methods would have yielded predictable results with a reasonable
`expectation of success.

`
`
`Sato discloses a signal processing unit that generates image signals by using the output signals of the image
`sensing device.
`
`
`According to the present invention, there is provided an image signal reproduction device
`comprising an image signal expansion processor, a display and a resolution setting
`processor.
`
`The image signal expansion processor expands a compressed image signal to reproduce an
`image with a predetermined resolution. The display, which indicates the image, includes an
`inherent resolution which is a maximum permissible resolution. The resolution setting
`processor sets the predetermined resolution, which is incremented from a lower resolution
`to a higher resolution. The predetermined resolution set by the resolution setting processor
`is lower than or equal to the inherent resolution.
`
`
`
`
`
`
`
`
`
`
`Sato at 1:40-61.
`
`
`Further, according to the present invention, there is provided an image signal reproduction
`device comprising an image signal expansion processor for expanding a compressed image
`signal to reproduce an image with a predetermined resolution, a resolution setting processor
`incrementally setting the predetermined resolution to be lower than or equal to a maximum
`permissible resolution, and a display indicating the image, the display including an inherent
`resolution equal to the maximum permissible resolution.
`
`In the electronic still camera 10, an optical image obtained by a photographing optical
`system (not shown) is formed on a light receiving surface of a CCD (charge coupled
`device) 11, so that the optical image is photoelectrically-converted to an electric charge
`signal by the CCD 11. The electric charge signal, which is an analog image signal, having
`been outputted from the CCD 11, is converted by an A/D converter 12 to a digital image
`signal.
`
`An image signal processing circuit 13 is provided for subjecting the digital image signal
`to various kinds of image processing. A frame memory 14, provided for storing the digital
`image signal, is connected to a frame memory controller 15, which is connected to the image

`
`signal processing circuit 13. The digital image signal outputted from the A/D converter 12 is
`temporarily stored in the frame memory 14, through the frame memory controller 15, and is
`subsequently read from the frame memory 14, to be compressed by the image signal
`processing circuit 13.
`
`
`Sato at 3:42-59.
`
`
`The video memory 18 is connected to a video memory controller 19, which is connected to
`the image signal processing circuit 13. Thus, the image signal is stored in and read from the
`video memory 18, through the video memory controller 19. The image signal read from the
`video memory 18 is inputted into an LCD controller 21, in which a synchronization signal is
`added to and an image signal processing, such as a gamma correction, is performed on the
`image signal, so that a video image signal is generated. The video image signal is then
`inputted into a display device 22 via an input terminal 23 provided in the display device 22.

`
`Further, Horii discloses a signal processing unit that generates image signals by using the output signals of the
`image sensing device.
`
`
`In still another aspect of the present invention, there is provided an image taking apparatus
`comprising: an optical lens; an image taking sensor having at least first and second image
`taking modes and adapted to operate in two or more image taking modes; first image
`processing means for processing image signals taken by the image taking sensor; an A/D
`converter for A/D-converting the image signals taken by the image taking sensor; storage
`means for storing the image signals converted into digital signals by the A/D converter;
`second signal processing means for processing the digital image signals stored in the
`storage means; mode switching means for switching the mode for processing the image
`signals taken by the image taking sensor between the first and second image taking modes;
`and control means, which, when the first image taking mode is selected by the mode
`switching means, causes signal processing to be performed by the first signal processing

`Horii at 3:7-31.
`
`
`Then, the image signal taken is subjected to signal processing by the signal processing means
`117, and supplied to the D/A converter 120 without being stored in the first memory 118.
`Subsequently, in step P2, the image signal converted to an analog signal is encoded by the
`encoder 121, and output as a video signal, thereby displaying the moving picture taken.

`
`The display device 22 includes a liquid crystal display (LCD) 24 and a resolution
`recognition unit 25, which is provided for recognizing an inherent resolution of the LCD 24.
`The inherent resolution is a maximum permissible resolution of the LCD 24.
`
`Sato at 4:20-24.
`
`
`The present invention relates to an image reproduction device, which, based on an image
`signal outputted by a CCD, for example, reproduces and indicates an image on a display.
`
`
`Sato at 1:5-8.
`
`
`When the image signal, stored in the frame memory 14, is read therefrom and then stored in
`the video memory 18 (see FIG. 1), some pixel signals are thinned or disregarded from the
`image signal, in accordance with the inherent resolution of the LCD 24, except when the
`inherent resolution has a value greater than a predetermined value. In the context of this
`specification, “thinning” is a process of reading only every [thinning number +1]th pixel,
`i.e., the thinning number is the number of skipped or disregarded pixels (per pixel read). The
`number of thinned pixels becomes greater as the inherent resolution becomes lower. Namely,
`in the case of the LCD 24 being of type D (160×120 pixels), pixel signals are only stored in
`the video memory 18 on every eighth pixel (i.e. an eight pixel separation in both the
`horizontal and vertical directions of the image), so that an image having a satisfactory
`number of pixels, which conforms to the inherent resolution of the LCD 24, is generated,
`and subsequently indicated by the LCD 24, while the expanded image data, stored in the
`frame memory 14, maintains the resolution of the original image signal, i.e., in this case,
`1280×960 pixels. The reason is as follows: Since the inherent resolution of the LCD 24 is
`160 ×120 pixels, only ⅛ of the pixels in both the horizontal direction and the vertical
`direction of the original 1280×960 pixel image (FIG. 2, F1) can be indicated by the LCD 24.

`Sato at 7:8-32.
