Image pickup system for reproducing image data using sensitivity function

Abstract

In a sensitivity function measuring unit, a CMD for picking up a beam from a light source is arranged through a photographic lens and a liquid crystal lens. A preamplifier, an A/D converter, a subtractor, a sensitivity function memory, a compressor, and R, G, and B sensitivity function memories are sequentially connected to the CMD through a switching circuit. An image reproducing unit for reproducing an original image using a sensitivity function calculated by the sensitivity function measuring unit is connected to a calculator for calculating a reproduced image, a frame memory for storing an image signal picked up by the CMD, and calculators for calculating sensitivity functions stored in the sensitivity function memories. The image reproducing unit is also connected to a display unit.
