Problems solved by technology
At present, the video content on the Internet is rich in variety and quantity, but the quality is uneven, such as poor light and dark levels of images, etc., which affect the viewing effect
[0003] At present, in the contrast adjustment scheme, the contrast is generally enhanced according to the average brightness of the partition in the image. For example, the brightness of the area with a darker average brightness is reduced, and the brightness of the area with a brighter average brightness is raised to increase the contrast between light and dark to achieve local contrast. Enhancement, after enhancement, it may appear that the distant scene is clearer than the near scene, but according to the visual experience, the far scene in the general image will appear blurred than the near scene, so when the clarity of the distant scene When it is higher than the close-up, the human eye will appear inverted, which will affect the overall display effect of the picture

The invention provides an image processing method and device, and the method comprises the steps of dividing a first image into at least two sub-regions, and estimating the depth of field of each sub-region; according to the depth of field of each sub-region, adjusting the contrast of each sub-region to obtain an adjusted second image; and displaying the adjusted second image. According to the method, the contrast ratio is improved, the depth of field of the image can be improved, and the image display effect is improved.
Description
technical field [0001] The present application relates to the technical field of image processing, and in particular to an image processing method, device and storage medium. Background technique [0002] With the rapid development of technology and the TV industry, intelligentization has become an inevitable trend in the current TV industry, and more and more users choose to use TV to watch online videos. At present, there are many types and quantities of video content on the Internet, but the quality is uneven, such as poor light and dark levels of images, etc., which affect the viewing effect. [0003] At present, in the contrast adjustment scheme, the contrast is generally enhanced according to the average brightness of the partition in the image. For example, the brightness of the area with a darker average brightness is reduced, and the brightness of the area with a brighter average brightness is raised to increase the contrast between light and dark to achieve local c...
