Abstract
An image processing apparatus capable of performing a correction process by filtering speedily and easily. A digital signal processor captures image data including effective area data from within a preset range of an image pickup device and ineffective area data from outside the preset range of the image pickup device. The digital signal processor superimposes a defective pixel detection signal and an ineffective image data detection signal to thereby generate a defective pixel determination signal. When a target pixel in the image data is determined based on the defective pixel determination signal as a determined-as-defective pixel, the digital signal processor corrects the value of the target pixel using values of the image data associated with ones, which are not determined, based on the defective pixel determination signal, as the determined-as-defective pixel, of pixels around the target pixel.
