Abstract
In the image processors and the image processing methods of the present invention, the number of bits for quantizing image data is adjusted on the basis of a dynamic range of each block. Therefore, the error introduced by encoding is reduced without increasing the data amount of the encoded image data, and the response speed of a liquid crystal can be controlled appropriately by preventing unnecessary voltages from being applied due to the error introduced by encoding.
