Problems solved by technology

That is, under the same video signal, there are obvious and visible differences in picture color between different devices
At the same time, if one of the screens in this system fails to work, it is necessary to replace the same manufacturer and the same batch of products. In extreme cases, if the manufacturer is located abroad, even small power supplies and spare parts will be replaced in an emergency. It is necessary to fly to the manufacturer for maintenance, which will inevitably bring great objective difficulties to system maintenance.
[0003] On the other hand, in some very standardized fields, such as: medical diagnostic electronic equipment (X-ray, stomach / colonoscopy, etc.), the same patient is checked on different equipment to obtain pictures with color difference, which only brings great harm to patients and doctors. come confused

Embodiment Construction

[0032] At first, explain the system of the present invention and working principle:

[0033] like figure 1 As shown, the full-color video display correction processing system of the specific embodiment of the present invention includes a video output module 11, a color space conversion unit 12 and a display device 5; wherein: the color space conversion unit 12 can be an independent device or connected with the video output module 11 integrated together. By corresponding to the color space conversion units 12 respectively, the display effects of different display devices 5 are completely consistent, thereby avoiding a high dependence on the display devices. That is: add a signal processing device to the signal input end of the display device to eliminate the color difference between the display devices. Its realization principle is:

Abstract

The invention relates to a full-color video displaying correction method. The method includes using a colorimeter to allow a display device with incoming 'full red', 'full green' or 'full blue' measurement signals to specifically display corresponding chromaticity coordinates and brightness values; and establishing a color-space transform linear equation by the measurement signals to calculate a color-space transform matrix, multiplying corresponding equal video signals and incoming video signals needed by the display device after color-space transformation, and sending the processed video signals to the display device for displaying.

Description

technical field [0001] The invention relates to display and display correction, in particular to a full-color video display correction processing method, and in particular to display correction of an LED screen combination system and a large-scale combination screen TV wall display correction. Background technique [0002] Super large LED combination screen and LED screen combination system are widely used in indoor and outdoor occasions. As a new media, the luminous graphics and texts of sports are easier to attract people's attention, with a large amount of information, updated at any time, and have very good advertising and notice effects. At present, these systems all use the same manufacturer and the same batch of products to ensure the same display effect, showing a consistent picture or an overall coordinated display effect. This is because color display devices, especially LED displays, are affected by raw materials and production processes, and color differences of...
