ABSTRACT:
Image data pixels indicative of the pixels in a noise-reduction target area having a size of 5×5 pixels is extracted from a plurality of types of CCD-RAW data having red, green and blue color components. A filter for reducing uncorrelated noise is calculated. Uncorrelated noise is removed by performing a filter operation using the calculated filter while correlativity of the CCD-RAW data is maintained. These processing steps are repeated for one frame of CCD-RAW data. After uncorrelated noise has been removed, spatial pixel processing such as an aperture correction is applied.
