Abstract:
A video display device includes: a receiver receiving video information including a bit string which defines a gradation value of an input image with a first frame rate; a video generator generating output images including multiple frames corresponding to a one-frame input image, based on the received video information; and a display displaying the generated output images for each frame rate. The bit string includes an upper bit, a middle bit, and a lower bit which are arranged in descending order therein. The upper bit corresponds to a number of gradations per frame of the output images. The video generator varies the gradation value among multiple frames in the output images according to the middle bit of the input image, and performs spatial dithering to correct the output images according to the lower bit of the input image.
