PROBLEM TO BE SOLVED: To execute a digital filter processing for obtaining a soft-focus effect at high speed. SOLUTION: The filtering processing is applied to original image date held in an image shorage part 6 by a filter whose all coefficients are one in a filtering processing part 7. Then, the original image data is added to picture data after filtering by an optional ratio in an image adding part 8, so that the soft-focus effect is obtained at high speed. |
