no. 1 example

[0022] Such as Figure 1A As shown, an image display control method provided in the first embodiment of the present invention includes steps:

[0023] S11: receiving an input image;

[0024] S12: Perform brightness component mapping processing on the target pixel data of the input image;

[0025] S13: Convert the target pixel data processed by the brightness component mapping from the color separation color space to the base color color space;

[0026] S14: Perform filtering processing on the target pixel data converted to the luminance component mapping process of the primary color color space; and

[0027] S15: Outputting the filtered target pixel data image to the display screen for image display.

[0028] To facilitate a clearer understanding of this embodiment, specific examples are given below to describe the foregoing steps S11-S15 in detail.

[0029] In step S11, the received input image is typically a primary color color space image, such as an RGB image, so in thi...

no. 2 example

[0068] Such as image 3 As shown, the display screen control system 30 in the second embodiment of the present invention includes: a sending card 31 , a receiving card 33 and an LED display screen 35 ; the receiving card 33 is connected between the sending card 31 and the LED display screen 35 . Specifically, the sending card 31 typically includes sequentially connected video interfaces, video decoders, programmable logic devices such as FPGA devices, PHY chips, output interfaces, and memory used with programmable logic devices, but this embodiment does not use This is the limit. The receiving card 33 typically includes sequentially connected network ports, PHY chips, programmable logic devices such as FPGA devices and busbars, and memory used in conjunction with programmable logic devices, but the present embodiment is not limited thereto; in addition, it is worth mentioning It should be mentioned that the number of receiving cards 33 connected to the sending card 31 is not ...

[0073] The display screen control system in the third embodiment of the present invention has the same hardware architecture as that of the display screen control system 30 in the second embodiment, and will not be repeated here. The difference is that the image brightness enhancement processing is completed by the sending card and the receiving card together, the specific process can be found in Figure 5 , which is a schematic diagram of the brightness enhancement process related to the third embodiment of the present invention.

[0074] Such as Figure 5 As shown, after receiving the input RGB image, the sending card converts it into a YUV image and calculates the Y component, and conducts segmental statistics on the Y component of the entire image to obtain the probability statistics of N segments and sends it to the receiving card; after that, the receiving card On the one hand, based on the probability statistics and brightness adjustment factors of each segment (For ...

Abstract

The embodiment of the present invention discloses an image display control method and device and a display screen control system. For example, it receives an input image, performs brightness component mapping processing on the target pixel data of the input image, and maps the brightness component to the target pixel after processing. The data is converted from the color separation color space to the primary color color space, the target pixel data converted to the primary color color space after the brightness component mapping processing is processed, and the filtered target pixel data is output to the display screen for image display. Therefore, the brightness and contrast of the displayed image can be effectively balanced, and the brightness of the image can be enhanced without losing the gray scale.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an image display control method, a display screen control system and an image display control device. Background technique [0002] At present, LED display has gained more and more market attention due to its high dynamic and high color, and more and more advertisers and merchants are more inclined to choose LED display as their promotion and publicity media, and the display The longer service life will lead to a decrease in the display brightness, which will seriously affect the display effect of the display and affect the normal use of the user; there are also some outdoor display screens that are not bright enough due to the limitations of the display equipment. Great inconvenience has been brought to the user. Contents of the invention [0003] Embodiments of the present invention provide an image display control method, a display screen control system, and an ima...
