Patent ID: 7245319

Claim:
A digital image shooting device comprising: an image forming lens; an image sensor element; a data processing unit for processing an output signal from said image sensor element into digital image data; an image memory for storing the digital image data and a lens characteristic relating to the image forming lens; and a lens characteristic correction unit for performing, by using the stored lens characteristic of said image forming lens and a position of a frame image photographed, a process of correcting a deterioration of an image quality derived from said image forming lens upon the digital image data, to obtain processed image data, before a shooting of a next frame of an image, in which the processed image data is stored in said image memory prior to the shooting of the next frame, or during the shooting of the next frame onward, in which the processed image data is stored in said image memory during or after the shooting of the next frame, wherein the digital image data comprises three primary color-based image data; and wherein the lens characteristic correction unit calculates a first deviation quantity of a first color-based image data due to the deterioration of the image quality, the first color-based image data selected among the three primary color-based image data, and calculates second deviation quantities of two color-based image data other than the first color-based image data on a basis of the calculated first deviation quantity, the second deviation quantities representing relative quantities to the first deviation quantities, and performs the process of correcting the deterioration of the image quality using the first deviation quantity and the second deviation quantities.
