Abstract

PURPOSE: To perfectly negate the effect of errors in A/D conversion and eliminate the need for high-accuracy A/D converting part by performing A/D conversion and comparison of exposure time information and the voltage signal changing with the time for acutually giving the exposure time with the same A/D converter.
