Abstract
PURPOSE: To perform an automatic compensation for an inverted light from the photo-current characteristic of a light receptor element by connecting a light receptor element in parallel and with an inverted light into a finder to a light receptor element in parallel and with an inverted polarity in the case where an inversion input and a non-inversion input of an operational amplifier are coupled to a light receptor element which measures the brightness of an object.
