SYSTEM OF DYNAMIC RANGE THREE-DIMENSIONAL IMAGE

摘要

PURPOSE: A dynamic range 3D image system is provided to obtain a dynamic range higher than the range when a 3D image is obtained. CONSTITUTION: An HDR(High Dynamic Range) generating module(440) generates a signal which shows the saturation degree of the pixel signal based on pixel signals detected by a pixel detecting module. The HDR generating module couples the pixel signals. The HDR generating module obtains a dynamic range image. A gain control signal generating module(430) outputs an output signal based on the size of a signal which shows the saturation degree of the pixel signal. The output signal is for supplying a voltage necessary for a gain control terminal of an optical detector.
