Embodiment Construction

[0020] In order to disclose the above and other objects, feature, advantages, it will be apparent to the preferred embodiments, together with the accompanying drawings, and will be described in detail.

[0021] Different types of display output devices such as cathode rays, projectors, and liquid crystal panels, which have different color gamut. In order to reproduce the color between different types of devices or different types, the color gamut difference between the input and output devices is required. This process is technically called a color gamut mapping.

[0022] Please refer to figure 1 It shows a block diagram of the color gamut processing system 1 of the preferred embodiment. The color gamut processing system 1 includes an input unit 10, a determination unit 20, a processing unit 30, an output unit 40, and a color gamut database 50. The color gamut processing system 1 is configured to perform color gammatic mapping processing to the display of the display to accuratel...

Abstract

The invention provides a color gamut mapping method and a color gamut processing system. The color gamut mapping method includes: pre-classifying a color gamut mapping lookup table to establish multiple sub-lookup tables; receiving an input image signal; and determining whether the color point of the input image signal is within the target color gamut of the display; and if the color point of the input image signal is not within the target color gamut of the display, using the plurality of sub-lookup tables based on the color point of the input image signal One of the lookup tables performs gamut mapping on the color points to obtain the output image signal. The present invention can effectively reduce the memory space occupied by the color gamut mapping lookup table and reduce the memory access time.

Description

Technical field [0001] This discloses a method of processing related to color signals, in particular, to a color gamut mapping method and a color gamut processing system. Background technique [0002] When the color gamut mapping of the display, there are two color points in the color gamut to the color gamut. The calculation mode of the two color points is different, in which the color point in the color gamut can be obtained directly by the formula, and the color gamfield is required to perform a color gamut outside the color gamut (ie, not in the target color gamut). The calculation of the color gamut mapping needs to be calculated by the retrorebral band, which allows it to spend longer operational time regardless of the software or hardware. [0003] To overcome the above problems, the existing color gamut mapping is calculated to pre-establish a color gamut map lookup table to facilitate the use of check-up methods in color gamut to reduce the operation time. However, the c...
