ABSTRACT OF THE DISCLOSURE An apparatus for scrolling the display of images obtained from a plurality of data units, each having pattern signals representing a plurality of horizontal lines and a corresponding color signal includes a video display having a plurality of horizontal display lines, a first memory for storing the pattern signals formed with first addresses corresponding to the plurality of horizontal display lines and a first buffer area for temporarily storing received pattern signals, a second memory for storing the color signal formed with second addresses ccrresponding to the numbers of the data units and a second buffer area for temporarily storing a received color signal, the pattern signals and a corresponding color signal being stored in the first and second buffer areas, respectively. A read out system operates so that the first memory, including the first buffer area, is read out by accessing the first addresses in a pre-determined order and so that the second memory, including the second buffer area, is read out by accessing the second addresses in a pre-determined order. Also provided is a circuit for transferring the pattern signal of a horizontal line stored in the first buffer area to a corresponding address of the first memory and for transferring a corresponding color signal stored in the second buffer area to a corresponding address of the second memory, and a circuit for supplying the pattern signals and the corresponding color signal to the display tube. -1-
