Embodiment 1

[0041] like figure 1 As shown, a display multi-window image independent calibration method, including:

[0042] Step 1: Test the characteristics of the display screen: Divide the display screen into multiple equal blocks, test the feature data of each equal block, and store them in the feature storage module;

[0043] Step 2: calling feature data: the multi-window parameter management module sends window position information, and calls out feature data of all equal blocks occupied by the window currently to be calculated from the feature storage module;

[0044] The third step: synthesizing the window characteristic curve: using the number of pixel points occupied by each equal block in the window and the characteristic data of each equal block to re-synthesize the characteristic curve;

[0045] Step 4: Calibration curve: Calculate the current window curve according to the type of calibration curve sent by the multi-window parameter management module;

[0046] Step 5: Update...

Embodiment 2

[0053] like figure 1 As shown, a display multi-window image independent correction system includes a feature acquisition control module, an equal block feature test image generation module, a feature storage module, a curve calculation module, a curve correction module, an image display control module, and a multi-window parameter management module and multi-window video stream synthesis module.

[0054] The output end of the feature collection module is connected to the input end of the feature storage module and the equal block feature test image generation module respectively; the equal block feature test image generation module output is connected to the image display control module input end; the feature storage module output end is connected to the The output end of the curve calculation module is connected; the output end of the curve calculation module is connected with the input end of the curve correction module; the multi-window parameter management module is respec...

Abstract

The invention discloses a display multi-window image independent correction method and system, and the method comprises the steps: equally dividing a display screen into a plurality of equal blocks, and carrying out the test to obtain the feature data of each equal block; obtaining window information needing to be calculated currently, and obtaining feature data of all equally-divided blocks occupied by a current window; re-synthesizing a characteristic curve of the window by using the number of pixels of each equal block occupied in the window and the characteristic data of each equal block order, and calculating a new curve; obtaining a correction curve type, and calculating a current window curve according to the correction curve type; updating the idle curve table by using the new curve, and switching the current window curve to the updated curve table after updating; synthesizing a new video stream according to the information of the multi-window parameter management module; calculating a window to which each pixel point position of the video stream belongs, and selecting a corresponding window curve table to correct the video stream so as to obtain a corrected video stream; and sending the corrected video stream to a display screen for display.

Description

technical field [0001] The invention relates to the technical field of display processing, in particular to a method and system for independently correcting multi-window images of a display. Background technique [0002] With the development of display technology, the size of display devices is getting larger and the resolution is getting higher and higher. This enables composite multi-window video signals from multiple input channels to be displayed on one display. [0003] At present, the whole display adopts a curve correction, which will be inaccurate for the display of video signals that need to be synthesized by different correction methods. Contents of the invention [0004] Purpose: In order to overcome the deficiencies in the prior art, the present invention provides a method and system for independently correcting multi-window images of a display. [0005] Technical solution: In order to solve the above-mentioned technical problems, the technical solution adopt...
