Abstract
Disclosed are a display control unit and a control method therefor, for permitting images provided by a plurality of video image sources to overlie, whereby an area of an overlying image plane wherein an original video image source that is composed of lines and shade patterns is displayed by interpolating an original image, and whereby an area wherein an original video image source that is composed of video images is displayed non-interpolated without interpolation. According to the present invention, whether or not the interpolation on image data is required is determined for each pixel by employing a changed value of luminance for each pixel between scan lines, a color difference signal, and color data. Even when a computer image and a video image are displayed on the same screen at the same time, optimal display can be performed on the individual image planes.
