Abstract

PURPOSE: To eliminate the need for a large-capacity frame memory stored with the whole data to be displayed by displaying the whole data to be displayed in a frame memory even when the size of the data to be displayed is larger than the size of the frame memory.
CONSTITUTION: The data 1 to be displayed are converted by a magnification converting circuit 3 to magnification based on magnification information 2 determined in consideration of the size of the frame memory 4 and the size of the displayed data 1 and then stored in the frame memory 4. The data stored in the frame memory 4 when read out for display operation are converted to optional magnification by a magnification converting circuit 6 according to an instruction of magnification information 5 and then converted by a video signal output circuit 7 into a video signal 8, which is outputted.
