Abstract:
1. An image data processing method for determining a voltage applied to a liquid crystal in a liquid crystal display device based on image data representing a plurality of frame images successively displayed on the liquid crystal display device, comprising: generating primary reconstructed preceding frame image data representing an image of a preceding frame by compressing current frame image data representing an image of a current frame, delaying the compressed image data by one frame interval, and decompressing the delayed image data; calculating an amount of change between the image of the current frame and the image of the preceding frame; generating secondary reconstructed preceding frame image data representing the image of the preceding frame, based on the current frame image data and said amount of change; generating reconstructed preceding frame image data representing the image of the preceding frame, based on an absolute value of said amount of change, the primary reconstructed preceding frame image data, and the secondary reconstructed preceding frame image data; and generating compensated image data having compensated values representing the image of the current frame, based on the current frame image data and the reconstructed preceding frame image data.
