rejection. See In re Warner, 379 F.2d 1011, 1017, 154 USPQ 173, 178 (CCPA 1967),

With this as background, we analyze the prior art applied by the examiner in the
rejection of the claims on appeal.
Cox's invention provides an apparatus capable of producing an arbitrarily large
number of video pixels without reducing the frame rate at which the apparatus can be
operated. This objective is achieved by running multiple relatively small sensor arrays
in parallel, thus providing a large number of pixels per video frame. These pixels are
grouped into individual segments corresponding to the field of view of each of the small
sensor arrays. Accordingly, each segment needs to be spliced together to form a
contiguous ultra-high-resolution image. This splicing needs to take place at both the
front and the rear end of the system. Multiple video cameras outputs must be spliced
together to create a single ultra-high-resolution video signal such as an RS-343
real-time video signal. In this case, a scan converter is used which takes the incoming
parallel video signals, digitizes them and feeds a memory array or buffer. This memory
array can be read out in a high speed serial sequence while it is being fed by the
incoming video. The digital data is then converted back to analog. Video sync signals
are then added to the analog signal thus creating an RS-343 video signal.
