Abstract: In an image data processing device of the invention, an image memory sequentially stores input image data of multiple frames. A write control module controls a writing operation into the image memory, and a read control module controls a reading operation from the image memory. A driving image data generation module generates the driving image data from read image data sequentially read from the image memory. The driving image data generation module generates the driving image data by replacing at least part of the read image data with regard to selected pixels with mask data. The mask data is set corresponding to a pixel value of the read image data in each of the selected pixels to be replaced with the mask data. This arrangement of the invention effectively reduces blur of a moving image displayed by the image display device, while preventing a significant decrease in luminance level of the displayed image.

Abstract: A liquid crystal display device has a liquid crystal panel module, sampling circuits that sample video signals a timing adjustment module driving signal generators and a dummy element. The timing adjustment module detects a variation in signal delay in the driving signal generators with a temperature change or with time, as a phase difference of an output signal from the dummy element relative to a reference signal. The timing adjustment module adjusts the phase of the timing signal corresponding to the detected phase difference. This arrangement corrects a temporal deviation of the sampling circuit driving signals from the video signals, which is caused by the variation in signal delay in the driving signal generators, and thereby effectively restrains the occurrence of ghost.
