PICTURE GENERATING DEVICE, PICTURE GENERATING METHOD AND COMMUNICATION DEVICE WITH PICTURE GENERATING DEVICE

摘要

Screen control means 106 determines a priority order, a magnification or reduction rate, and an image synthesis position. Image selection means 101 selects a plurality of input images in conformity with the priority order, and image processing means 102 magnifies or reduces the selected images in proportion to the magnification or reduction rate. Movement detection means 103 detects stationary parts of images to be processed in the image processing means 102, and frequency analysis means 104 detects featureless parts of the images to be processed in the image processing means 102. Adapted image synthesis means 105 synthesizes the magnified or reduced images at an image synthesis position designated by the movement detection means 103 and the frequency analysis means 104. Thereby, even if an image of an object to be displayed is added besides an opposite station image and a self image, the images can effectively be synthesized and displayed. Even if the resolution of a display apparatus is changed, an image generation apparatus can flexibly cope with the change. And, it can be prevented that a child screen hides an important part of a parent screen from sight.
