Abstract
A solid state image pick-up device comprises a matrix of first and second photo-sensitive elements, vertical shift registers disposed parallel to each other to shift charges from the first and second elements, respective transfer gates between each first and second element and the adjacent vertical shift register, and a horizontal shift register connected to one end of each of the vertical shift registers. An optical shutter is controlled such that the first and second elements are simultaneously exposed to incident light, and a system controller controls the transfer gates and the vertical and horizontal shift registers whereby equal predetermined maximum intervals are available for charging each of the first and second elements, the predetermined intervals being at least two frame periods long, but the starting time for charging for the first and second elements being relatively shifted by a predetermined interval, and reading of the signals from the first and second elements being performed sequentially in a frame period subsequent to closure of the shutter.
