<p>PURPOSE:To facilitate picture-in-picture image processing by moving a mouse point or the like to execute adjustment such as the expansion/contraction of a picture formed by superposing a 2nd image on a part of a 1st image screen. CONSTITUTION:A specification point pointed out by a point specifying means is moved to the lower right corner of the 2nd image on a monitor 9 while operating the mouse 8 and prescribed operation for starting expansion processing is executed. When the specification point is moved to a required position by operating the mouse 8 again, an arithmetic means calculates displayed data so that the lower right corner of the 2nd image coincides with the moved specification point, an image superposing circuit adjusts the size of the 2nd image, a vertical/horizontal ratio, etc., based upon the display data and superposes the adjusted data to the 1st image. Thus image processing called as picture-in- picture can easily be executed.</p> |
