System and method for image motion compensation of a CCD image sensor |
摘要 |
An electronic system and method for minimizing the loss of image sharpness caused by image motion during the exposure interval of a camera using electro-optical area array image sensors is provided. Differential speed clocking is performed using a set of parallel shift registers to achieve improved image motion compensation ("IMC") performance. A large number of rows and columns contained in a CCD array are arranged in a variable number of row segments. In situations where IMC is needed, a variable frequency clocking method can be applied to these row segments in the CCD array. This method of parallel shift clocking provides for IMC in a reconnaissance system in low light conditions where narrow shutter widths are not practical. An aerial reconnaissance system user utilizing this IMC method can perform forward oblique reconnaissance missions in a straightforward manner. Complexity in CCD design and processing is reduced with this approach, which is utilized in either a small or large array format CCD.
