Automatic color temperature adjustment method

Abstract

The invention provides an automatic color temperature adjusting method, which comprises the following steps: detecting white point data on a to-be-tested object;, setting a color temperature and a specification of the white point data to obtain a three primary color coordinate value; outputting the maximum brightness signal value of the three primary color coordinate value to obtain first color information; outputting the lowest brightness signal value of the three primary color coordinate value to obtain second color information after adjustment; calculating the first color information and the second color information to obtain a signal value of the color temperature of the white point data; using the signal value to obtain the signal intensity to know the distance between a target whitepoint and the white point data; and adjusting the position of the white point data by means of the target white point to complete the adjustment of the color temperature of the white point data. The method can quickly calculate and adjust the signal strength to be adjusted of the white point by operation and greatly improves the production efficiency.

Description

technical field [0001] The present invention relates to a color temperature adjustment method, in particular to an automatic color temperature adjustment system through computer calculation. Background technique [0002] Since the early days of cathode ray tubes, display products have gradually grown and improved, and now the product specifications have developed into liquid crystal displays. In the process of display product development, high-end products tend to display accurate colors, and the requirements for white point specifications of displays are more stringent. Strictly speaking, the white point and chromaticity of general display products have large variability before adjustment. Before leaving the factory, the three primary colors (RGB) signals need to be set independently for each display to achieve white balance processing. [0003] Therefore, for the processing of color temperature adjustment, the industry has begun to develop many technologies, such as US Pat...

Problems solved by technology

[0004] However, although the above-mentioned conventional technology can solve the parallax problem caused by the naked eye judgment, it is not helpful for quantifying the production performance of the product, or although the conventional technology has achieved the automatic adjustment of signal strength to complete the white point specification, it cannot be corrected in the calibration step , takes too long
