Image drawing method, image drawing apparatus, recording medium, and program

Abstract

An image drawing technique includes a method of drawing a randomly changing image of an object and a method of drawing a revised image including a shimmering image in a background image. The method of drawing a randomly changing image of an object establishes a drawing pattern of the object, the drawing pattern including a plurality of extraction areas, each extraction area including a portion of the drawing pattern. A portion of the drawing pattern is extracted from one of the extraction areas and is combined with a randomly selected mask pattern to draw a composite image which is output on a monitor. The extracting and combining steps are repeated for a next extraction area located at a predetermined distance in a defined direction from a previous extraction area. The method of drawing a revised image includes randomly altering a portion of the background image to generate an altered image, and combining the altered image and another mask pattern to generate another composite image. The another composite image is combined with a remaining portion of the background image to draw the revised image. The another composite image and the revised image are output for display on a monitor.
