Problems solved by technology

However, in the above image brightening methods, the RGB value of each pixel in the image is generally enhanced, which can easily lead to the following problems: the color in the image is excessively close to gray, and the color of the brighter area is enhanced. Distortion phenomenon, become blurred
Image distortion leads to the loss of details in the distorted area, and often the image distorted area may be the user's attention area, such as the face area in the image

Embodiment Construction

[0029] The technical solution of the present application will be further described below in conjunction with the accompanying drawings and through specific implementation methods. It can be understood that the specific embodiments described here are only used to explain the application, rather than limit the application. In addition, it should be noted that, for the convenience of description, only some structures related to the present application are shown in the drawings but not all structures.

[0030] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe the steps as sequential processing, many of the steps may be performed in parallel, concurrently, or simultaneously. Additionally, the order of the steps can be rearranged. The process may be terminated when its operations are complete, but may also have additional s...

Abstract

An embodiment of the present application discloses an image processing method, a device, a storage medium, and an electronic device. The method comprises the following steps of: acquiring an image ofa color mode of color brightness separation; performing scene recognition on the image to determine a scene of the image; traversing a luminance component of each pixel point in the image, and generating a luminance distribution of the image according to a traversal result of the luminance component; generating a brightness mapping relationship based on a standard brightness distribution corresponding to a scene of the image and a brightness distribution of the image; adjusting a luminance component of each pixel point in that image according to the luminance map relationship to generate a first processed image. By adopting the technical proposal, the embodiment of the present application can achieve the best effect for images of different scenes on the basis of ensuring that the images are not distorted, and the applicability of the image processing method is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image processing, and in particular, to an image processing method, device, storage medium, and electronic equipment. Background technique [0002] With the rapid development of electronic devices, electronic devices such as mobile phones and tablet computers have image acquisition functions, and users have higher and higher requirements for the quality of images collected by electronic devices. [0003] At present, after the image is collected, the image is generally brightened, so that the darker area in the obtained image is brighter, and the details that are difficult to distinguish by the naked eye are displayed, and the clarity of the entire image is improved. However, in the above image brightening methods, the RGB value of each pixel in the image is generally enhanced, which can easily lead to the following problems: the color in the image is excessively close to gray, ...
