Abstract

PURPOSE:To enable to set an output at operation easily, by changing an aperture of an optical system of an image sensor, or interval of control signals so that the total amount of light at operation can be about 50-90% of the total amount of light at a limit point. CONSTITUTION:When a counter counts clocks C and reaches a scheduled amount m, a control signal D is outputted for preset. Thus, since the number m can be designated by selecting the number externally by means of a switch, a variable storage time can be set. The illuminance of a sensor photodetector plane can be changed by adjusting an aperature 4. Through the means, the illumination of photodetection or optical storage time reaching the photodetector plane 5a of an image sensor 5 can change the output sensitivity of the image sensor 5, allowing to adjust the output sensitivity.
