ABSTRACT:
There is provided a liquid crystal display control device which can display pictures in a magnification mode by using only a memory having low-speed access and a low storage capacity. When a video signal has intermediate resolution or less, the enlargement processing is performed by a frame memory, a line memory and an enlargement processing control circuit. If the input operation and the output operation to and from the frame memory are synchronized with each other, it is sufficient for the frame memory to have a storage capacity of two lines. When the video signal has the same high resolution as a liquid crystal display panel, the video signal is output through a gate circuit to a display timing generating circuit, and it is displayed in a through mode. In this case, no processing is performed by the frame memory or the like.
