ABSTRACT:
While image data is written into either one of first, second, third frame memories1, 2and3, image data are repetitively read two times from the remaining two memories in one vertical synchronization interval and transferred to an arithmetic unit4, and this operation is executed with the frame memories changed sequentially. An arithmetic unit4refers 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 unit4transfers image data of a value greater than the data value of the current image signal to a liquid crystal display device5. Thus, the step response characteristic is improved for the improvement of the dynamic image display quality.
