ABSTRACT:
An image synthesizer of an image editing apparatus not only stores image data of two or more source images and includes a display device for displaying an image according to received image data, but also is provided with an address generator which, controlled by a data processor, transmits address signals sequentially to have a synthesized image of these source images displayed such that the individual source images appear superposed and transparent to each other. Each pixel of the display device displays only one of the source images and area densities of pixels displaying each of the source images very over the two-dimensional screen of the display device. When one of the source images is superposed on top of another, a pattern is stored in a pattern memory such that pixels displaying one of the images are scattered into the area of the other image according to the pattern such that the boundary between source images can be made controllably less conspicuous.
