An image sensor causes a solid-state imaging device, at the scanning of an image, to release in succession a dark current signal generated in the solid-state imaging device and a scanning signal containing said dark current signal, subtracts said dark current signal from said scanning signal by a differential circuit to obtain an image signal corresponding to said image, and so regulates by means of an integrating time control circuit and in response to the level of said image signal, the image signal integrating time of said solid-state imaging device a...
A radiation sensing system comprising: (A) radiation sensing means of the signal integrating type arranged to produce a dark current signal and a radiation sensing signal containing the dark current signal; (B) means for conducting dark current compensation on said radiation sensing signal on the basis of said dark current signal and for producing a dark current compensated sensing signal; (C) means for controlling a signal integrating time of said sensing means on the basis of said dark current compensated sensing signal; (D) means for detecting the con...
