Zusammenfassung:PROBLEM TO BE SOLVED: To automatically correct image deterioration due to the fading in color of a developed still photographic film. SOLUTION: This device consists of a reading part 331 which reads a standard pattern for fading correction of each color of R, G and B that are previously printed in parts other than an image picking up part of a film, a fading deciding part 332 which decides the degree of fading of each color of R, G and B of the film based on the read standard pattern for fading correction, a lookup table 333 that previously has plural R, G and B tables for fading correction which correspond to the degree of fading of each color of R, G and B and reads an optimum table for fading correction in accordance with the decision results by the part 332 and an image signal processing circuit which corrects respective R, G and B image signals based on the read table for fading correction and then outputs them to a video monitor. Thus, even when film images of a developed still photographic film fade in color, it is possible to reproduce them without any fading states at all times.
