ABSTRACT:
The image processing method and apparatus acquire input image data from the image recorded optically with a taking lens, acquire the information about the lens used to record the image and perform image processing schemes on the input image data using the acquired lens information, provided that the type of the lens used is identified from the acquired lens information and the intensity of sharpness enhancement of the corresponding image is altered in accordance with the identified lens type. The characteristics of the taking lens may also be acquired from the lens information and using the obtained lens characteristics as well as the position information for the recorded image, the input image data is subjected to aberration correction for correcting the deterioration in image quality due to the lens characteristics, provided that the information about the focal length of the taking lens effective at the time of image recording is additionally used, or image processing schemes are performed in two crossed directions of the recorded image, or parameters for correcting aberrations in the imaging plane of the taking lens are scaled such that they are related to the output image data on a pixel basis. High-quality prints reproducing high-quality images can be obtained from original images that were recorded with compact cameras, digital cameras and other conventional inexpensive cameras using low-performance lenses.
