Precision Control Technology of Exposure Time for Full-Frame CCD Digital Camera
全帧型CCD数码相机曝光时间的精确控制

A Precision Control Technology for the Exposure Time of the Full-Frame CCD Aerial Camera is introduced.The schedule time of TRG and the control pulse are designed based on the precision working time of shutter.The integral time for the sensitive area of CCD can be controlled by the cooperation of electronic shutter with mechanic shutter.The precision of exposure time for CCD is enhanced.The design is simple,and no excess circuit is needed.It can be applied in CCD digital camera with high precision resolving...
