  • Patent number: 8970612
    Abstract: The present invention provides an image processing device, including a buffering unit, a minifying unit, a synchronous dynamic random access memory (SDRAM), an overdriving unit, a comparing unit, a restoring unit, and an output controlling unit. The present invention further provides an image processing method and a liquid crystal display incorporated with the image processing device. The image processing device, the image processing method, and the liquid crystal display incorporated with the image processing device will not only directly perform the overdrive-processing of an input high-resolution image, but will also, on the one hand caches an input high-resolution image by the buffering unit, and on the other hand minifies an input high-resolution image. As a result, the image data is already reduced when the overdrive-processing performs, and the consumption of the space of the SDRAM is also accordingly reduced.
