An imaging apparatus detects and registers fixed-noise pixels as those pixels of the image sensor which produce fixed pattern noise, and includes an optical element which disperses light that is incident on the image sensor. The detection is performed by identifying isolated high-luminance pixels within captured images and, for each isolated high-luminance pixel, evaluating the luminance values of peripherally adjacent pixels. A judgement is made as to whether an isolated high-luminance pixel is a fixed-noise pixel based upon comparing luminance values of the peripherally adjacent pixels with a predetermined threshold value, the judgement preferably being performed only while images are captured during hours of darkness. |
