Abstract
Abstract A device using signal integration and storing type image sensing means having the functions of generating an electrical signal corresponding to the integrated amount of incident light, storing it, and putting out said stored signal in time-sequential or -seriated manner. This device is provided with control means for controlling the signal integrating and storing operation of said image sensing means. The control means is arranged to control the signal integration and storing operation of the sensing means so that the signal integrating and storing cycle of the image sensing means is made equal to an integer multiple of about 50 mm sec.
