Embodiment Construction

[0022] The specific embodiments of the method and system for noise reduction of a display screen, a computer device and a readable storage medium of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] refer to figure 1 , figure 1 Shown is a flowchart of a method for denoising a display screen according to an embodiment, including the following steps:

[0024] S10, detecting the brightness parameter of the current display frame of the display device;

[0025] In the above steps, after a display device such as a TV is started, the brightness of each frame displayed on the display can be detected, and the brightness parameters of the frame of the display can be identified, so as to obtain the average brightness value of the display in the required time period, etc. Displays the brightness data of the screen.

[0026] S20, acquiring an average brightness value of the brightness parameter within a preset time period;

Abstract

The present invention relates to a method and system for noise reduction of a display frame, a computer device and a readable storage medium. The method comprises: detecting the brightness parameters of the current display frame of a display device; obtaining the average brightness value of the brightness parameters in a preset time quantum; and obtaining noise reduction parameters corresponding to a brightness range where the average brightness value is located according to the preset corresponding relation of the noise reduction parameters and the brightness range, and performing noise reduction processing of the current display frame according to the noise reduction parameters. The method and system for noise reduction of the display frame, the computer device and the readable storage medium allow the noise reduction parameters employed by the noise reduction processing of the display device to match the average brightness value of the current display frame so as to improve the noise reduction effect of the noise reduction processing of the current display frame and improve the display effect of the display frame.

Description

technical field [0001] The present invention relates to the technical field of signal processing, and in particular, to a noise reduction method and system for a display screen, a computer device and a readable storage medium. Background technique [0002] Display devices such as TV sets have been widely used in people's life and work. The display screen noise reduction technology of display devices can effectively reduce the display interference caused by noise such as granular noise on the displayed screen. It is cleaner and softer, but at the same time, the above noise reduction function may also reduce the clarity of the corresponding display screen, make the screen displayed by the display device blurred, and reduce the viewing quality of the display screen. [0003] In the process of noise reduction of the display image of the display device, it is usually necessary to reduce the noise while maintaining the clarity of the image. The more noise is reduced, the lower the...
