Embodiment 1

[0114] The invention provides a color temperature curve correction method, the method comprising:

[0115] S1. Obtain a preset color temperature curve of the display device;

[0116] S2. Select any gray scale interval, and obtain the optical data of the display image corresponding to the end value of the gray scale interval;

[0117] S3. In the gray scale interval, select a gray scale corresponding to a display image that satisfies the image display standard, and acquire optical data corresponding to the gray scale display image; and

[0118] S4. Insert the color temperature value corresponding to the gray scale into a preset color temperature curve to correct the color temperature curve.

[0119] For the 10bit video image system, the gray scale of 0-1024 is divided into 4 intervals, [1000, 600], [600, 300], [300, 100], [100, 0].

[0120] The gray scales are 1000, 600, 300, 100, and 0 respectively as sampling points, control the display device to display the gray scale image o...

Abstract

The invention discloses a color temperature curve correction method, system and device and a medium. The method comprises the steps of obtaining a preset color temperature curve of a display device; any gray scale interval is selected, and optical data of a display image corresponding to the end value of the gray scale interval is acquired; and in the gray scale interval, selecting a gray scale which corresponds to a display image and meets an image display standard, acquiring optical data corresponding to the gray scale display image, and inserting a color temperature value corresponding to the gray scale into a preset color temperature curve to correct the color temperature curve. The method comprises the following steps: segmenting a gray scale, respectively inserting one or more points in each segmented interval, and correcting a color temperature curve by adopting a point complementing mode; in the correction process, a linear interpolation mode is adopted for the RGB points, so that each input value has a single adjustment value, a test signal can be adjusted to the maximum extent, and a standard picture is obtained.

Description

technical field [0001] The present application generally relates to the technical field of electronic equipment, and specifically relates to a color temperature curve correction method, system, equipment and medium. Background technique [0002] Monitor is the product series that has the highest requirement for color management among display products. This product is applied in the field of radio and television broadcasting, in order to create sufficiently realistic and shocking film and film and television broadcasting images. A good monitor is needed as a picture reference in the early stage of production. [0003] In terms of the display performance of the monitor, the most important thing is the correction of the color temperature. The same color at different color temperatures will make the viewer feel different feelings. The lower the color temperature, the warmer the picture you see; the higher the color temperature, the cooler the picture you see. Correct color t...
