To provide a display unit for displaying an image on a screen having aspect ratio different from a video signal without distorting the image utilizing an effective screen up to the maximum. The whole image information in a horizontal cycle of an input video signal is compressed on time base by signal processing means to generate a new video signal corresponding to display means. Synchronizing signals HD" and VD" corresponding to the new video signal generated by the signal processing means are generated based upon synchronizing signals HD and VD separated from the input signal by synchronizing signal generating means. In display means composed of a vertically deflecting circuit, a horizontally deflecting circuit and CRT, scanning by an electron beam is controlled according to the synchronizing signals HD" and VD" and a video signal compressed on time base is displayed on CRT. <IMAGE> |
