Restoration of Deteriorated Color Photographic Images by the Color Scanner Loaded with GIS

Abstract

Restoration of deteriorated (faded and discolored) color photographic images by use of the color scanner loaded with GIS (golden imaging software) was tested. In this scanning process, the values of the maximum (shadow) and the minimum (highlight) densities of the deteriorated images were read and supplied to the scanning program. Then the restored image having the color characteristics corresponding to that of original film was obtained automatically according to the function of GIS. The deteriorated color target and pictures were processed and evaluated by CIELAB color difference and gamut. It was shown that the proposed method is effective for the restoration of deteriorated pictures by subjective and objective evaluation.
