Brightness correction method, system and device and computer readable storage medium

Abstract

The invention discloses a brightness correction method, system and device and a computer readable storage medium. The method comprises the steps that a projection drawing obtained after a target projection device projects a detection drawing is determined; performing region division on the projection drawing to obtain a corresponding projection division region; determining area brightness attenuation information of each projection division area based on the brightness of the detection image and the projection image; determining pixel point brightness attenuation information of a preset numberof pixel points in the target projection equipment according to the area brightness attenuation information; and determining brightness correction information of the target projection equipment according to the pixel point attenuation information, and performing brightness correction on the target projection equipment based on the brightness correction information. According to the invention, thebrightness correction information of the target projection equipment can be quickly determined based on the projection division area, thereby achieving the quick brightness correction of the target projection equipment, and improving the watching image quality of the projection equipment. The brightness correction system and device and the computer readable storage medium provided by the inventionalso solve the 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...
