摘　　要：提出一种全帧型CCD数码相机曝光控制方案.在测量机械快门机械延时的基础上,控制CCD触发脉冲TRG和机械快门的控制时序,使得带电子快门的CCD相机,在机械快门的配合下,CCD的感光区都能按各种设计要求的曝光时间精确曝光,从而有效的提高了照片的分辨率.该方法设计简单,不需要额外的硬件电路,可以广泛应用于带机械快门的CCD数码相机曝光时间的精确控制中.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 power widely.
