Method and system for providing a soft tone effect to a digital or digitised image

摘要

An image processing system for correcting digital image data read from a photographic medium. This system includes a diffusing process unit (23) for effecting a diffusing process on an original image composed of the digital image data, thereby to generate a diffused image, and an image correcting unit (25) for generating a corrected image by effecting synthesis between the original image and the diffused image. The system further includes a synthesizing coefficient calculating unit (24) for calculating a synthesizing coefficient for each pixel of the diffused image by using a pixel value of the diffused image as a parameter. The image correcting unit (25) generates the diffused image by effecting the synthesis between the original image and the diffused image according to the synthesizing coefficient. In this, the synthesizing coefficient determines a ratio of the pixel value of the diffused image relative to the pixel value of the corrected image.
