Image processing method, image processing apparatus, and liquid crystal display using same

摘要

A display, an image processing apparatus and an image processing method for producing excellent visual images while suppressing the accumulation of quantization errors related to increasingly complex digital image processing. Among a variety of image processing, processing which can be represented by look-up tables (LUT) such as constant number multiplication and constant number addition/subtraction is performed equivalently by changing reference values in a reference gray-level signal generator of a display. Thus, the operation of a digital image processing unit can be simplified, and there is obtained the display making the most use of the output dynamic range while suppressing the occurrence and accumulation of quantization errors.
