Abstract:
An image processing method for use in shutting light processing, comprising:forming an unsharp image signal in a first image processing apparatus, which represents an unsharp mask image to be used for the shutting light processing, wherein the unsharp image signal is formed from an original digital image signal to be used for the shutting light processing;performing compression processing on the unsharp image signal and the original digital image signal, a compressed unsharp image signal and compressed original digital image signal being thereby formed in the first image processing apparatus; andreproducing the compressed unsharp image and original digital image signals in a second image processing apparatus;performing decompression processing on said compressed unsharp image and original digital image signals, a decompressed unsharp image signal and a decompressed original digital image signal being thereby obtained in said second image processing apparatus; andperforming shutting light processing by combining the decompressed unsharp image signal with the decompressed original digital image signal in the second image processing apparatus.
