<p>The present invention provides an image processing device, which comprises a buffer unit, a reduction processing unit, a synchronous dynamic random access memory (SDRAM), an overdrive processing unit, a comparison unit, a recovery processing unit, and an output control unit. The present invention also provides an image processing method and a liquid crystal display. In the image processing device and method and the liquid crystal display provided by the present invention, overdrive processing is not directly performed on an input high-definition image, but instead, the input high-definition image is buffered in the buffer unit and is meanwhile reduced, so that the data amount of the image is reduced in actual overdrive processing, the consumed SDRAM space is correspondingly reduced, the number of the SDRAM does not need to be increased for inputting of high-definition images, and the cost is easy to control. During output, a static image is directly output; and for a dynamic image, the image subjected to overdrive processing and recovered to the original definition is output, so as to maintain the image quality.</p> |
