Patent ID: 8213733

Claim:
An image processing apparatus comprising: an extracting means for extracting a partial image corresponding to an object from an entered image; first calculating means for calculating a plurality of types of correction parameters with regard to respective ones of a plurality of types of correction processes to be executed based on image information of the partial image; first generating means for generating first conversion parameters reflecting respective ones of the plurality of types of correction parameters calculated by said first calculating means; second calculating means for calculating, using a calculation method different from a calculation method of said first calculating means, a plurality of types of correction parameters with regard to respective ones of a plurality of types of correction processes to be executed based on image information of the entered image; a second generating means for generating second conversion parameters having a format common with that of the first conversion parameters, the second correction parameters reflecting respective ones of the plurality of types of correction parameters calculated by said second calculating means; and image correction parameter generating means for adding the first conversion parameters and the second conversion parameters in accordance with a predetermined ratio, thereby generating image correction parameters for correcting the entered image.
