and the reply brief.
The Examiner argues that Alkofer does teach persistently
storing the image signal and computed histogram. The Examiner
points us to figure 6, memory 34, and histogram memory 54. See
pages 3, 4, 5, 6, 7, 8, and 12 through 16 of the Examiner’s
answer.
Turning to Alkofer, we find that Alkofer is a method of
processing a digital color image derived from photographic film.
See column 1, lines 8 through 10. We further find that Alkofer
states that figure 6 is a schematic diagram showing scan printing
apparatus. See column 3, lines 61 and 62. Alkofer teaches the
details of figure 6 in column 4, line 24, through column 5, line
68. There, Alkofer teaches that the input device includes a
light source 20 and lens 22 for projecting an image of a color
negative film 24 onto three solid state image sensing arrays 26.
The image sensor 26 scans the color photographic negatives to
produce three color separation signals R, G and B. The signals
thus produced are supplied to analog-to-digital converters 32.
The digital color image signals produced from the analog-to-
