PROBLEM TO BE SOLVED: To obtain a device which is capable of performing a filter processing in a small storage area and is easy in the filter processing by providing a storage means, a designation means designating plural filters and a means performing plural designated filter processings for an original image. SOLUTION: When an original image 1 is held in a buffer and a filter processing is performed for the original image, the original image 1 is held in an AND buffer 3. A filter group 5 composed plural filters is preliminarily designated, this filter group 5 is used for the original image 1, a processed image 7 is obtained and this processed image 7 is superscribed on the original image 1 on the buffer. When the kind of the filter is changed, the plural filters within the filter group 5 are designated again and the filter group 5 is used for the original image 1 held in the AND buffer 3. Therefore, only one AND buffer 3 is required. Further, when an area designation is performed for the original image 1, the filter processing is performed for the image within the area. |
