Abstract

PURPOSE:To obtain a digital quantity, which is correctly proportional to the quantity of incident light, even in the case of weak light by effecting conversion to the digital quantity with the use of an AD converter after a preset quantity of electric signals are added to the either signals which are produced by photoelectric converting means.
