摘要：
A camera with defective pixel compensation is provided. The camera comprises a register and a compensating unit. The compensating unit receives an image datum and a plurality of adjacent image data relating to the image datum and, according to the value installed in the register, the compensator selects a reference datum from the plurality of adjacent image data. When the image datum is greater than the reference datum by a threshold value, the compensating unit modifies the image datum according to the reference datum.
