Abstract
An image signal output unit converts an image on a film, which has undergone photography, into an image signal. An image storage unit stores the image signal. A read unit reads the identification code of a camera which is recorded on the film which has undergone photography. An information storage unit stores image quality degradation information and the identification code in pairs. An image processing unit reads out the image quality degradation information from the information storage unit on the basis of the identification code read by the read unit, and corrects the image signal stored in the image storage unit by using the read image quality degradation information.
