Embodiment Construction

[0015] The specific implementation manner of the color correction method based on the custom light source duty cycle of the present invention will be described in detail below with reference to the accompanying drawings.

[0016] figure 1 A flow chart of a color correction method based on a custom light source duty cycle is shown in an embodiment, including the following steps:

[0017] Step S10: According to the current duty cycle of each color of the multi-screen display device and the displayed chromaticity and brightness, respectively calculate the unit duty cycle brightness of each color light source.

[0018] In one embodiment, the process of calculating the unit duty ratio luminance in step S10 may include the following:

[0019] In step S101, the duty cycle of each color of each display unit of the multi-screen display device is acquired.

[0020] In this step, it is mainly to read the duty cycle of the current state of each color of each display unit of the multi-sc...

Abstract

The invention discloses a method and a system for color correction based on the customized light source duty ratio. The method includes the steps: respectively computing unit duty ratio brightness of each color light source according to the duty ratio of the current state of various colors of a multi-screen display device and chromaticity and brightness displayed by the multi-screen display device; when target white is corrected, computing the correction duty ratio of the color light sources according to the unit duty ratio; and correcting each color light source of the multi-screen display device by the aid of the correction duty ratio. By the method and the system, respective correction duty ratio of the color light source of each display unit is customized to meet the target white, chromaticity consistency of the target white displayed by the display units can be guaranteed from the source, and correction display effect of the display units is improved.

Description

technical field [0001] The present invention relates to color correction technology, in particular to a color correction method and system based on customizing the duty cycle of a light source. Background technique [0002] A multi-screen display device (such as a splicing wall) is a large-screen display system composed of multiple display units and image controllers, and is generally used for super-large-screen display of one screen and multi-window display of multiple screens. Due to the difference in the color of the light source of each display unit, the color properties of the light source (such as RGB light source) of different display units are different in actual display, resulting in the duty cycle of each light source of each display unit being different from when the light source is adjusted to the target white color. The required duty cycle does not match, so that each display unit of the multi-screen display device has poor consistency when displaying the target...
