Title: Image processor and image processing program
Inventor: OTA KEIZO
IPC: G06T5/00
Filed: 2001-11-12
Abstract: PROBLEM TO BE SOLVED: To provide an image processor in which a modulated image can be generated by effectively blurring only a portion looking notched. SOLUTION: Four images are generated by shifting an 'original image' before anti-alias processing upwards, downwards, to the left and to the right just by one pixel, and a difference image is generated by taking the difference of color information for every pixel between the image shifted upwards and the image shifted downwards. In the image shifted to left and the image shifted to right, a difference image is similarly generated. The product of difference values is calculated for each pixel from these two difference images, and the 'degree of edge' is calculated for every pixel. Then, an output image is generated by mixing the 'original image' and the 'blurred image of the original image' for every pixel corresponding to the 'degree of edge'. As a result, the modulated image having only the edged portion blurred effectively can be provided.
