ABSTRACT:
An image processing method for obtaining processed color image signals from image signals on a silver halide photosensitive material, having the following steps: transforming color image signals into a luminance signal and color information signals; applying a high-frequency component suppression processing to the color information signals; decomposing the luminance signal into a luminance low-frequency component signal, a luminance medium-frequency component signal, and a luminance high-frequency component signal; applying a processing, in accordance with requirement, to the luminance low-frequency component signal; applying a suppression processing to the luminance medium-frequency component signal; applying an emphasis processing to the luminance high-frequency component signal; composing a processed luminance signal through combining the processed luminance low-frequency component, the processed luminance medium-frequency component signal, and the processed luminance high-frequency component signal; and transforming the processed luminance signal and the processed color information signals into a set of processed color image signals.
