Pixel art is effective means for row resolution display. It is need long time to draw pixel art manually. Video game publishers often come to use polygons, because they want to reduce making game time and computers become high performance. But pixel art is sometimes better express than polygons. If they make pixel art easily, scopes of pixel art field expand for one method of expression. Our research purpose is to draw outline, especially size of pixel art by photograph. First, we investigate procedure of drawing and connected direction of outline to find pixel art's feature. Pixel art outline width is often one pixel. Existing methods can't draw one pixel outline. By the way, we reduce binarized picture by existing methods, then outline become unsharp grayscale image or losing outline information. To solve this problem, we propose a method making outline pictures by photograph and reduction outline. Then we can draw a binarized outline & edge image for pixel art.
