1. A motion image display apparatus comprising:

  • a high speed bus which is capable of transferring motion image data at a required frame rate;

    a video input device for digitizing an analog video signal by converting said analog video signal into a digital video data;

    a memory device for storing data;

    a scaling device for scaling said digital video data from said video input device in the horizontal or the vertical direction and forming scaled motion image data in real time;

    a destination address table having a plurality of entries each of which specifies a start address at which a beginning of a scaled motion image data is to be stored or read from said memory device on a line by line basis;

    a data transfer device which transfers on said high speed bus, said scaled motion image data or a portion of said scaled motion image data from said scaling device of a continuous address area to said memory device by using said destination address table and transfers, on said high speed bus, said scaled motion image data from said memory device to a display for displaying thereon using said destination address table; and

    a color space converter which converts color format of said scaled motion image data from said data transfer device to a format apparatus for said display.
