摘要： A display device having an on-screen display (OSD) function receives a YUV video signal such as the camera video signal or broadcast video signal of YUV format from a camera or recording medium, receives an RGB-OSD signal from a circuit device (serial interface) of another system different from this YUV video signal, causes a memory within an OSD processor to store the OSD signal, converts an RGB video signal resulting from conversion of the YUV video signal to a panel-matched RGB video signal synchronized with a display synchronization signal, reads a panel-matched RGB OSD signal from the memory of the OSD processor in synchronism with this display synchronization signal, composes those RGB video signal and OSD signal, using an OSD composer, and supplies the resulting RGB composite video signal and the display synchronization signal to a display panel.

摘要： 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.
