Problems solved by technology
[0002]Due to the limitation of sensor precision used by most display devices and mainstream cameras, high dynamic scene shooting has become the bottleneck of most multimedia technologies at present; what traditional display devices can display Scenes, videos, and images are usually limited by hardware devices, and usually can only express a small part of the brightness range. For example, a common 8-bit image displays an integer range from 0 to 255. Therefore, in order to be able to display the impact of high dynamic range, it is necessary to To realize the mapping from high dynamic range images to low dynamic range images, and the emergence of different display devices, it is necessary to realize the mutual conversion between high dynamic range images and low dynamic range images; Save a part of the detail features, so that the brightness effect can achieve the goal of being close to the real scene acceptable to the human eye. There is still a lot of room for optimization in the existing technology

The embodiment of the invention discloses an image processing method and a related product, and is characterized in that the method is applied to electronic equipment; the method comprises the following steps of: the electronic device obtains an initial image, the initial image is mapped to obtain a first image, the first image is processed according to a preset strategy to obtain a second image,the preset strategy is used for adjusting the contrast ratio of the first image to optimize an image display result, and finally sharpness enhancement processing is performed on the second image to obtain a target image; the global contrast and the local contrast are adjusted through the preset strategy, so that a high-dynamic-range scene can be better displayed on equipment with a low dynamic range, an existing image processing method can be optimized, and the high efficiency and convenience of image processing can be improved.
Description
technical field [0001] The present application relates to the technical field of image processing, in particular to an image processing method and related products. Background technique [0002] Due to the limitation of sensor precision used by most display devices and mainstream cameras, high dynamic scene shooting has become the bottleneck of most multimedia technologies; the scenes, videos and images that traditional display devices can display are usually limited by hardware devices, usually only Express a small part of the luminance range, for example, a common 8-bit image displays an integer range from 0 to 255, so in order to be able to display the impact of high dynamic range, it is necessary to realize the mapping from high dynamic range images to low dynamic range images, and With the emergence of different display devices, it is necessary to realize the mutual conversion between high dynamic range images and low dynamic range images; how to maintain the overall ch...
