An apparatus and method for efficiently executing a correction of false colors, such as purple fringe or the like, caused by chromatic aberration to produce and output high quality image data. White non-gradation pixels are detected from image data, and a false color pixel detected area is established around the detected white non-gradation pixels. In the established area, pixels having a color corresponding to the false color such as purple fringe or the like are detected, and the detected pixels are specified as false color pixels. The specified false color pixels are corrected based on a periphery pixel value. This arrangement allows an efficient detection of false color area of the purple fringe or the like occurring in the vicinity of the white non-gradation pixels, and also allows a partial pixel value correction, thereby allowing the production and output of high quality image data without affecting the whole image. ® KIPO & WIPO 2007 |
