Abstract

The application discloses a brightness correction method, system, device and computer-readable storage medium, which determines the projection image obtained after the target projection device projects the detection image; divides the projection image into corresponding projection division areas; based on the detection image and the brightness of the projection map, determine the regional brightness attenuation information of each projection divided area; determine the pixel brightness attenuation information of the preset number of pixels in the target projection device according to the regional brightness attenuation information; determine the target according to the pixel attenuation information brightness correction information of the projection device, and perform brightness correction on the target projection device based on the brightness correction information. In the present application, the brightness correction information of the target projection device can be quickly determined based on the projection division area, so that the brightness correction of the target projection device can be quickly performed, and the viewing quality of the projection device can be improved. The brightness correction system, device, and computer-readable storage medium provided by the present application also solve corresponding technical problems.

Description

technical field [0001] The present application relates to the technical field of image processing, and more specifically, to a brightness correction method, system, device, and computer-readable storage medium. Background technique [0002] In the application process of projection equipment, due to the optical structure of projection, near light is bright and far is dark, so that the brightness of the projected picture is the brightest in the middle and lower part, and the surrounding area is dark, which affects the viewing quality, especially the effect of short-focus projection. [0003] To sum up, how to improve the viewing image quality of the projection device is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] The purpose of this application is to provide a brightness correction method, which can solve the technical problem of how to improve the viewing quality of projection equipment to a certain extent. The present app...
