Abstract
An image processing method and apparatus compensate at least one aberration of a chromatic aberration of magnification and a distortion aberration, etc., by using position information of an image for input image data obtained from the image optically photographed by use of a photographic lens. In this case, an aberration compensating level is first set to an initial value, the input image data is subjected to a compensating process of the aberration, and thereafter the result is displayed on a monitor. A compensating level can be designated for the initial value at a plurality of stages. Each time when a compensating level is designated to one of the plurality of stages, the compensating process of the aberration is again performed for the input image data according to the compensating level of the designated stage. The aberration compensation result is displayed on the monitor. According to the method and apparatus, without lens characteristics being obtained, and to ensure to output as a photo print important information of images such as a main subject to be photographed, a deterioration of an image quality such as an aberration due to the lens characteristics can be compensated…
