    摘要: A color reproduction correcting system and method, and a video display device and method can reproduce original color by considering signal source and display device. Each signal source information and each display device information can be stored. The signal source and the display device, which are currently used (e.g., corrected), can be determined, for example, by a user selection. In one embodiment, the signal provided from a transmission side can be inverse gamma-corrected based on a corresponding signal source, and a colorimetric error of the inverse gamma-corrected signal is preferably corrected using corresponding signal source information and display device information. The corrected colorimetric error signal can be gamma-corrected based on a corresponding display device and then can be displayed on the corresponding display device.

    摘要: A liquid crystal display that is capable of improving a display quality of the LCD is disclosed, wherein gamma data for controlling the gamma voltage is stored for each of at least two modes. The gamma data for each mode is accessed in response to a selected mode, and n gamma voltages (wherein n is an integer), each having a different voltage level, indicated by the gamma data in the selected mode are generated. A lookup table is provided in which a color temperature correction data for correcting a color temperature characteristic of an input image is set in correspondence with a gray level value of the input image. The lookup table is accessed to read out color temperature correction data corresponding to the gray level value of the input image. The data lines are driven by the color temperature correction data.
