ABSTRACT:
The technique of the invention accurately detects a pixel defect in an image taken by an imaging device, such as a digital still camera. The image processing flow of the invention maps luminance data to respective pixels of a specified pixel array and computes a difference between the luminance data of each target pixel and an average value of the luminance data of four adjoining pixels on the top, bottom, left, and right of the target pixel. The presence or the absence of any pixel defect is detected according to the computed difference. The luminance data of an identified defective pixel detected as the pixel defect is corrected with the luminance data of adjoining pixels on the top, bottom, left, and right of the identified defective pixel.
