METHOD AND DEVICE FOR ELIMINATING DEFECTS IN A CCD CAMERA

摘要

A CCD camera comprising means for eliminating defects that reduce sensed image quality, and a method therefor, are disclosed. The defect elimination means are portable and built into the camera housing, and include electronic filtering means for filtering in real time each pixel of an image sensed at time Ti, by averaging it with the pixel at the same address in the image sensed at time Ti-1, as well as electronic means for comparing the image averaged in real time with a reference image taken at a predetermined time.
