Abstract:
An image processing method for use in shutting light processing, the method comprising the steps of:forming an unsharp image signal in a first image processing apparatus that represents an unsharp mask image to be used for the shutting light processing, wherein the unsharp image signal is formed from a digital image signal of an original digital image to be used for the shutting light processing, wherein said digital image signal represents the original digital image before being subjected to shutting light processing, and has gradation characteristics such that details of the image are maintained both in a highlight and shadow side of said digital image; performing compression processing on the unsharp image signal, a compressed unsharp image signal being thereby formed in the first image processing apparatus; reproducing the compressed unsharp image signal in a second image processing apparatus; performing decompression processing on said compressed unsharp image signal, a decompressed unsharp image signal being thereby obtained in said second image processing apparatus; and performing shutting light processing by using the decompressed unsharp image signal of the second image processing apparatus.
