Problems solved by technology

Although this method can effectively adjust the luminous brightness of the LED, due to the luminous characteristics of the LED itself, adjusting the current to control the luminance is prone to color shift, resulting in the problem that the color temperature parameters need to be readjusted, and it does not consider the adjustment. The change

Abstract

Embodiments of the present invention relate to a display brightness adjustment method, device, and system, and a computer-readable storage medium. The display brightness adjustment method, for example, includes: acquiring a brightness adjustment parameter value; setting a target parameter according to the brightness adjustment parameter value; and performing image processing on an original image signal according to the target parameter to obtain a target image signal, and according to the The target image signal generates a pulse width modulation control signal for controlling the target display device to perform image display, wherein the image processing includes gamma correction and brightness adjustment, and the target parameter is selected from the gamma value used for the gamma correction and one of the gray-scale brightness adjustment parameters for the brightness adjustment. When the brightness of the target display device is adjusted in the embodiments of the present invention, a smoother grayscale transition can be obtained visually by the human eye, thereby improving the image display quality of the target display device.

Description

technical field [0001] The present invention relates to the technical field of image processing and display control, and in particular, to a display brightness adjustment method, a display brightness adjustment device, a display brightness adjustment system, and a computer-readable storage medium. Background technique [0002] With the development of LED (Light Emitting Diode, light-emitting diode) display technology, LED display screens are currently used in various fields due to their advantages of low cost, low power consumption, high visibility, and freedom of assembly. With more and more application scenarios of LED displays, more and more attention has been paid to the adjustability and universality of LED display brightness. Brightness, indoor low brightness, etc.) to adjust the display brightness. [0003] In order to solve the above problems, the current prior art mainly adopts the current adjustment method to adjust the display brightness. The current regulation ...
