Image processing apparatus, image processing method, and computer program

Abstract

An apparatus and a method for efficiently executing correction of false color, such as purple fringe, caused by chromatic aberration and for generating and outputting high-quality image data are provided. A white-saturated pixel is detected from image data, a false-color-pixel detection area is set around the detected white-saturated pixel, and pixels having color corresponding to false color such as purple fringe are detected from the set area. The detected pixels are determined as false-color pixels and correction processing based on the values of the surrounding pixels is performed on the determined false-color pixels. With this configuration, an area of false color such as purple fringe generated in the neighborhood of a white-saturated pixel can be efficiently detected, pixel values can be partially corrected, and high-quality image data can be generated and output without affecting the entire image.

         27 . A method of automatically detecting and automatically correcting false color fringe, the method comprising:
 setting a false color detection area around a saturated area detected from input color image data;   performing color analysis on the color image data;   detecting a false color area using the false color detection area and a result of the color analysis; and   correcting the detected false color area based on pixel values of pixels surrounding the false color area.
