Appeal No. 2002-1460
Application 09/040,510
where the computed histograms are stored in the image recording
device. See page 1 of Appellant’s specification. Histogram
computations require a lot of processing time and present a
computational bottleneck. See page 2 of Appellant’s
specification. Figure 3 is a block diagram of an image
acquisition device constructed according to the invention. See
page 3 of Appellant’s specification. As shown in figure 3,
camera 14 includes an image sensor 16, which generates an analog
image signal. The analog image signal, A, representative of a
sensed image I, is sent to an analog-to-digital converter 18,
which converts analog image A into a digital image signal D. The
digital image signal D is sent in parallel to both the histogram
computation 28 and the end camera image processing 20. The
computed histograms are stored in histogram storage mechanism 30
of storage mechanism 22. See page 5 of Appellant’s
specification. The processed image signal from end camera image
processing 20 is stored in image storage 24 of storage mechanism
22. Information in a table links histograms with their
associated images and also are recorded. See page 6 of
Appellant’s specification.
