Patent ID: 8339341

Claim:
An image display system comprising: an image generation device that generates image data; and an image display device that receives said image data from said image generation device, performs overdrive processing based on said received said image data, and displays an image, wherein, said image generation device includes: a rendering circuit that generates said image data to be outputted to said image display device for every frame; a memory unit that holds plural pieces of said image data corresponding to at least two frames among plural pieces of said image data generated by said rendering circuit; and a transfer circuit that transfers plural pieces of said image data corresponding to two frames among plural pieces of said image data held by said memory unit to said image display device within one frame period, each of the transferred plural pieces of said image data corresponding to a single one of the two frames, and said image display device receives said plural pieces of said image data corresponding to two frames from said transfer circuit and performs the overdrive processing based on said received image data, such that the data of a current frame is transferred by the transfer circuit on one side of an effective image area and data of a perceding frame is transferred by the transfer circuit on another side of the effective image area.
