摘要： PROBLEM TO BE SOLVED: To prevent occurrence of halation in a pixel of a high luminance region and to prevent a change of color at a periphery of the high luminance region when a high sensitivity image obtained from a target pixel and a peripheral pixel of the target pixel is obtained.SOLUTION: A correction coefficient (K) to a sensitization image (Xs) is determined on the basis of a comparison result of a sensitization magnification (L) and first and second thresholds (TH1 and TH2) of a luminance value of the sensitization image (Xs). When the luminance value is below the first threshold, the correction coefficient takes a first fixed value. When the luminance value is the second threshold or more, the correction coefficient takes a second fixed value. When the luminance value is in a range from the first threshold to the second threshold, the correction coefficient gradually becomes small from the first fixed value to the second fixed value. The first fixed value is "1", for example, and the second fixed value is an inverse number of the sensitization magnification, for example.
