Problems solved by technology
The original technology has some obvious defects: 1. The color threshold setting is cumbersome, and it needs to manually modify the color parameter model
2 The color threshold setting model is relatively rough and cannot accurately describe the color characteristics of the LCD screen
3 The color threshold setting algorithm will be relatively slow, and each point needs to be compared repeatedly

Embodiment Construction
[0027] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.
[0028] please if Figure 1-Figure 3 As shown, the invention provides a kind of flat panel LCD heterochromatic detection method, and described method comprises:
[0029] Generate a 256*256*256 color statistics table 10 for counting the number of occurrences of the same color in all pixels;
[0030] Generate the color look-up table 20 of 256*256*256 in the color statistics table 10, compare and filter the color counted in the color statistics table 10 with the set threshold, and record in the color look-up table 20;
[0031] Each pixel in the image generates a binarized image according to the query result in the color lookup table 20 .
[0032] Specifically, first generate a 256*256*256 color statistics table 10, and then make statistics o...

The invention discloses a flat panel LCD heterochromatic detection method, a storage device and a mobile terminal. The method comprises: generating a 256*256*256 color statistical table for counting the number of occurrences of the same color in all pixels; generating a 256*256*256 color look-up table in the color statistical table, and performing a color search on the color statistical table The color counted in the image is compared with the set threshold, filtered, and recorded in the color lookup table; each pixel in the image generates a binary image according to the query result in the color lookup table. The color look-up table of the present invention is relatively simple to set up, easy to operate, and fast to use; the recognition efficiency of different colors is higher, and since the method of calculating the screen color statistics table is used to express the inherent color characteristics of the screen itself, the largest color model on the color model The collection close to the color itself; the running time is shortened, because the method of directly looking up the color in the color lookup table is adopted, so the calculation speed is faster than the threshold lookup.
Description
technical field [0001] The invention relates to the field of LCD heterochromatic detection, in particular to a flat panel LCD heterochromatic detection method, a storage device and a mobile terminal. Background technique [0002] LCD (short for Liquid Crystal Display) liquid crystal display. [0003] The structure of the LCD is to place a liquid crystal cell between two parallel glass substrates, set a TFT (thin film transistor) on the lower substrate glass, and set a color filter on the upper substrate glass, and control the liquid crystal molecules by changing the signal and voltage on the TFT. Rotate the direction, so as to achieve the purpose of controlling whether the polarized light of each pixel is emitted or not to achieve the display purpose. [0004] Now LCD has replaced CRT to become the mainstream, and the price has dropped a lot, and it has been fully popularized. [0005] The existing algorithm technology for different color detection of flat-panel LCD screen...
