PURPOSE:To provide an image pickup device in which an original picture can be exactly restored without being affected by an optical system even at the time of handling a continuous system and a discrete system. CONSTITUTION:In a sensitivity function measuring means, a CMD 10 which picks up a light from a light source 1 is arranged through a photographing lens 4 and a liquid crystal lens 5, and a pre-amplifier 12, A/D converter 13, subtracter 14, sensitivity function memory 16, compressor 17, and sensitivity function memories 19r, 19g, and 19b for R, G, and B are connected through a switching circuit 18 to the CMD 10 in this order. And also, in a picture restoring means which restores the original picture by using the sensitivity function searched by the sensitivity function measuring means, a calculator 28 which calculates the restored picture is connected to a frame memory 23 which stores a picture signal picked up by the CMD 10, each of calculators 26 and 27 which calculate the sensitivity function stored in the sensitivity function memories 19r, 19g, and 19b, and a display device 29. |
