Accumulation time adjusting device for photo-electric converter
 There is disclosed a device for correcting the accumulation time of a photoelectric converter composed of self-scanning charge-accumulation elements of plural bits on the basis of the average intensity to the incident light to the converter. The charge accumulation time is controlled by determining a reference value according to the maximum value of the output signals obtained from the photoelectric converter and comparing this reference value with the average intensity.
