Abstract
While image data is written into either one of first, second, third frame memoriesand, image data are repetitively read two times from the remaining two memories in one vertical synchronization interval and transferred to an arithmetic unit, and this operation is executed with the frame memories changed sequentially. An arithmetic unitrefers to a look-up table on the basis of two inputted data values and, when the data value of the current image signal is greater than the data value of the previous image signal, the unittransfers image data of a value greater than the data value of the current image signal to a liquid crystal display device. Thus, the step response characteristic is improved for the improvement of the dynamic image display quality.
