Abstract
Abstract According to the invention, when an image is drawn, a check is made to see if the image is overwritten onto an image which has already been inputted and displayed, thereby switching. For this purpose, a color of the image to be drawn and a color of the image which has already been inputted are compared and the image of the color of a higher priority is displayed. According to the invention, there is no need to reset a display priority of the image by a manual operation of the operator in consideration of the priority of the image. When the image is inputted, the priority of the image can be simultaneously decided. As targets to which the invention is applied, there are an image inputted by a hand-writing, an image inputted by a scanner, a character pattern which is generated from a character generator, and the like.
