Abstract
A signal processing apparatusis achieved, capable of processing an analog pixel signal Ag obtained by photoelectric conversion in a CCD image sensorsuch that noise will be reduced and S/N will be improved by interpolation in an area with low brightness or saturation on a display screen and resolution will be increased by edge emphasis in an area with high brightness or saturation on the display screen. The signal processing apparatusfor performing A/D conversion on the analog pixel signal Ag from the CCD image sensor, comprises an interpolation processing sectionfor adaptively switching interpolation processing for determining brightness or saturation of pixels for each pixel, and calculating a digital pixel signal of a target pixel from pixel signals of peripheral pixels positioned in the periphery of the target pixel based on the determined brightness or saturation of the target pixel.
