Abstract
The digital image shooting device is composed of an image forming lens, an image sensor element, a data processing unit for processing an output signal from the image sensor element into digital image data, an image memory for storing the digital image data; and a lens characteristic correction unit for performing a process of correcting a deterioration of an image quality derived from the image forming lens upon the digital image data by using a lens characteristic of the image forming lens and a position of a frame image photographed. The digital image shooting device is capable of obtaining the image quality which is high enough for the utilization even by using the comparatively low-price lens which does not exhibit a high performance.
