Embodiment Construction

[0033] figure 1 Shown is a block diagram of the color adjustment system in the 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 a good color adjustment result in the embodiment of the present invention, this embodiment uses a color test pattern (Test Pattern), adjusts the color distribution and color temperature of the color test pattern through the color distribution adjustment module 110, and then adjusts 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 via the saturation adjustment module 130 . Finally, the processing module 140 uses the adjusted color test samples to obtain gamma ramps (GammaRamps).

Abstract

The invention relates to a method and a module for adjusting the brightness. The method for adjusting the brightness comprises the steps of receiving a grayscale input signal, carrying out power calculation for the grayscale input signal with gamma parameters to obtain a first brightness adjusting multiplying factor and adjusting the grayscale input signal with the first brightness adjusting multiplying factor to obtain a grayscale output signal.

Description

technical field [0001] The present invention relates to a color compensation technology, and in particular to a compensation technology considering the color characteristics of the display itself. Background technique [0002] In today's highly technological society, electronic products have gradually integrated into people's home life. From entertainment TVs and game consoles to computers used at work, it shows 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 the needs of work or entertainment in life. [0003] Since different display devices can actually display different colors, in the technical field of color images, the term gamut refers to the number of colors that a color image device can actually display. Therefore, different display devices have their unique color gamuts. [0004] In order to enable display devices wi...
