Problems solved by technology

However, the gamma slope has a relationship from each input to output, so when the user inputs the required brightness, saturation or color temperature through the adjustment interface, the relationship from input to output in the gamma slope It must be recalculated. Therefore, when the user adjusts the screen, if the computer or graphics card is too slow, the screen will be prone to delay or flickering.

Embodiment Construction

[0034] figure 1 Shown is a block diagram of a color adjustment system in an embodiment of the present invention. Please refer to figure 1 , The color adjustment system 100 includes a color distribution adjustment module 110, a brightness adjustment module 120, a saturation adjustment module 130, and a processing module 140. In order to obtain good color adjustment results, the embodiment of the present invention uses a color test pattern to adjust the color distribution and color temperature of the color test sample through the color distribution adjustment module 110, and then adjust the color through the brightness adjustment module 120 The brightness of the test sample is tested, and the saturation of the color test sample is adjusted through the saturation adjustment module 130. Finally, the processing module 140 uses the adjusted color test samples to calculate Gamma Ramps.

[0035] However, those of ordinary skill in the art should know that in the above adjustment proce...

Abstract

The invention relates to a saturation adjusting method and a saturation adjusting module. The saturation adjusting method comprises the steps of adjusting the curvature of the curve of a special function at each position by a saturation parameter to obtain an adjustment function, substituting a color input signal into the adjustment function, and calculating a color output signal corresponding tothe color input signal.

Description

Technical field [0001] The present invention relates to a color compensation technology, and more particularly to a compensation technology that considers the color characteristics of the display itself. Background technique [0002] In today's highly technologicalized society, electronic products have gradually integrated into people's home life. From entertainment televisions and game consoles to computers used at work, they all show people's dependence on electronic products in daily life. Among them, display devices such as televisions, projectors, and liquid crystal displays are indispensable electronic products, whether for work needs or entertainment in life. [0003] Since different display devices can actually display different color types, in the technical field of color images, the term gamut refers to the number of color types that a color image device can actually display. Therefore, different display devices have their unique color gamut ranges. [0004] In order to e...
