Abstract
Soft-edge processing of a video color image is effected in accordance with a stylus nib pressure. Initially, a display circle unit is determined having center coordinance corresponding to display coordinance of a stylus and having a radius corresponding to a nib pressure of the nib stylus. A display region is set encompassing the display circle unit, the display region having a plurality of pixels. A distance from each pixel located outside the circle unit within the display region to the circle unit is determined. This distance is then used as the basis for determining a Z value of the pixel which is indicative of the relative illumination of the pixel to effect soft-edge processing of the image.
