Abstract
A liquid crystal display control device is provided with a clock generating circuit for generating, on the basis of a first synchronous signal, a dot clock having a predetermined period, a phase which varies on dot-period basis for every frame period of the first video signal, an input circuit for picking up the first video signal in accordance with the dot clock and outputting digital display data, a frame memory in which the digital display data are stored, and a control circuit for generating a second synchronous signal for a liquid crystal display and reading out the display data stored in the frame memory to generate a second video signal, whereby a series of operations from a pickup operation of the video signal to a display operation of the liquid crystal panel can be performed at a lower speed while suppressing deterioration in quality of display images.
