Embodiment approach

[0083] In the embodiment of the present application, after the first image is acquired, image processing may be performed on the first image to acquire at least one second image. A feasible implementation manner is as follows:

[0084] Step A. Obtain the display position parameter of the display interface control of the display device.

[0085] Step B, using the display position parameters to crop the first image to obtain a cropped first image.

[0086] Step C, performing region division on the cropped first image to obtain at least one second image.

[0087] In this embodiment, it is considered that when the display interface of the user equipment is displaying images, there are some user interface controls, which are always displayed and whose positions do not change. For example, for mobile terminals, there are users with fixed positions Interface controls include status bar, sliding bar, bottom buttons or picture-in-picture, etc. The display position parameter of the us...

Abstract

Embodiments of the present application provide an image processing method, device, display device, and readable storage medium, by acquiring a first image to be processed, performing image processing on the first image, and acquiring at least one second image; and counting each A histogram of the second image in at least two dimensions; according to the histogram of the second image in each dimension, identify whether the first image is an OSD image, and then use the enhancement strategy corresponding to the recognition result of the first image to the first image. Make an enhanced display. In the embodiment of the present application, by using at least two-dimensional histograms to determine whether the first image is an OSD image, the recognition of the OSD image can be effectively realized, and the recognition accuracy is high; at the same time, by using the first image to identify Results The enhanced strategy corresponding to the enhanced display of the first image can also effectively avoid the problem of negative display effects when the first image is an OSD image.

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, display device, and readable storage medium. Background technique [0002] In order to obtain a better display effect, mobile devices are often equipped with a display enhancement function to improve the contrast, sharpness and brightness of the picture. Usually, the display enhancement function is mostly used for watching videos and browsing pictures. [0003] At present, there are different enhancement strategies for images in different scenes. If the same enhancement strategy is used, some scenes will have negative effects. For example, the natural image scene and the text reading scene cannot use the same enhancement strategy. If the text reading scene The enhancement strategies using natural image scenes will produce distortion, ghosting and other negative effects. [0004] Based on this, in the p...
