Abstract

PURPOSE: To obtain purely only a signal output of image distinctness by rendering the photo-electroconversion characteristics of detecting element for the image distinctness and detecting element for the object brightness to be approximate in a simple and high accurate manner, and by subtracting an output for detecting the object brightness from a noise output due to the object brightness by the detecting element for image brightness.
