摘要：An image data circuit compensates sensitivity differences in image detectionbetween a pair of image sensors. The image sensors each include a plurality of chargestorage type optical sensing elements. Correction data indicative of sensitivity differencebetween the image sensors is stored in permanent memory. A clock pulse generatorcircuit generates clock pulses for counting charge storage periods indicated by outputsignals from the optical sensing elements. A pair of counter circuits counts the clockpulses and outputs count values corrected with the correction data and corresponding tothe charge storage periods. A pair of quantizing circuits converts the output signals toimage data based on the corrected count values.
