Abstract

PURPOSE:To enable a image recorder with good resolution to be obtained, by giving weighing to a sensitivity distribution in the one picture element of a solid-state image pickup element and varying this weighing. CONSTITUTION:The one picture element 2 of the solid-state image pickup element is constituted of a picture element 2A and the two small picture elements 2B and 2B' of both sides. The output Y of the picture elements 2B and 2B' is converted to the negative signal by a code conversion circuit 3 and the output Y is adjusted by an output control circuit 4 and compounded to the output signal Y of the picture element 2A. As the result of that, the sensitivity distribution of the picture element 2 is shown by a figure and (alpha) and (beta) and they are the distance from the center of the respective picture elements 2 to the end part of the picture element 2A and 2B (2B'). Besides, (h) can be freely changed by a connected adjuster 5. Therefore, effective edge effect can be obtained without depending on the rate of the size of the small picture element and the picture element in the center.
