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.
