Image processing method and device, computer readable storage medium and terminal

Abstract

The invention discloses an image processing method and device, a computer readable storage medium and a terminal. The method comprises the steps that first images to be processed with two or more kinds of exposure rates are acquired, wherein the first images with two or more kinds of exposure rates are images in a preset backlighting condition; intermediate exposure rate color values correspondingto the backlighting condition are adopted, the first images with two or more kinds of exposure rates are subjected to exposure processing, and final images are obtained, wherein the intermediate exposure rate comprises information of color value change of a same pixel point in the corresponding images with two or more kinds of exposure rates in the backlighting condition. According to the technical scheme, shot images in the backlighting condition can be processed, the quality of the obtained images is improved, and the use experience of a user is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and device, a computer-readable storage medium, and a terminal. Background technique [0002] Photographic technology can record instantaneous images, so it is widely used in various fields. For example, in the field of intelligent transportation, cameras are usually set up on both sides of the road to assist traffic supervision. When traffic violations and other scenes occur, the camera will take pictures of traffic lights, so that the images obtained by taking pictures can be used to monitor traffic conditions. [0003] However, in some environments with relatively strong backlight brightness, the camera tends to overexpose when taking pictures, resulting in image distortion. For example, when the camera used to assist traffic supervision takes pictures of red traffic lights, due to overexposure, the red traffic lights will appear wh...

Problems solved by technology

[0003] However, in some environments with strong backlight brightness, the camera tends to overexpose when taking pictures, resulting in image distortion

For example, when the camera used to assist traffic supervision takes pictures of red traffic lights, due to overexposure, the red traffic lights will appear white in the captured image, or even appear as bright colors such as yellow or white, resulting in image distortion

[0004] In the prior art, the image optimization algorithm is generally used to solve the problem of image overexposure, but the resulting image has the problem of poor quality, which affects the user experience
