An image processing apparatus and method of use, comprising; a first area 2b of an image is generated from pixels existing on a line of interest that is set so as to pass through a pixel corresponding to a correction target pixel (for example a defective or hot pixel). A plurality of second areas 2c are generated based on the positions of pixels existing on at least one reference lines that are set so as not to pass through the correction target pixel. The value of the pixel corresponding to the correction target pixel is corrected using a value of a pixel on each of the at least one reference lines, the value being determined based on the amounts of correlation between the respective second areas and the first area. The reference line may be parallel to the chosen line of interest. If a plurality of second areas exist possessing a highest amount of correlation, then the correction means computes the correction value using a value of a pixel which is found to be closest to the correction target pixel. The pixel extracted may have the same colour as that of the correction target pixel (i.e R, G or B). |
