Abstract

PURPOSE: To always operate a correct automatic exposure control, by detecting collectively each kind of variable amount immediately before photographing, and performing its processing with a comparator circuit, integrating circuit, reference voltage setter circuit, etc., and automatically correcting the variable amount.
CONSTITUTION: Immediately before photographing, the output from a detector 1 is detected by a peak detecting circuit 10, that is, a variable amount from time aging, temperarure change, etc. is detected immediately before irradiation of X-ray, and by compounding this variable amount additionally with the set voltage of a reference voltage setter 12, the variable amount, from time aging, temperature change, etc. immediately before X-ray irradiation, is automatically detected and corrected.
