IMAGE SIGNAL COMPENSATOR OF CCD CAMERA SYSTEM |
摘要 |
PURPOSE: An image signal compensator of a CCD camera system is provided to be capable of enhancing the quality of images photographed by the CCD camera by compensating the image quality damaged due to the defect of a problem in the CCD camera. CONSTITUTION: An adaptive gain controller(300) receives analog image signals from a CCD(200) to control the gain of the analog image signal in accordance with amplifying magnification data corresponding to the sensitivity of the CCD. A correlated double sampler(400) receives the gain controlled analog image signals to remove noise components by a correlated double sampling processing. An auto gain controller(500) amplifies the gain of analog image signals provided from the correlated double sampler(400) to a reference level.
