Embodiment Construction

[0048] Before the technical solutions of the embodiments of the present invention are described in detail, the related technologies are introduced first.

[0049] In related technologies, intelligent terminal devices such as mobile terminals and tablet computers have become an indispensable part of users' lives due to their portability, entertainment capabilities, and functional diversity. Users have higher and higher requirements and expectations for smart terminal devices, such as the need to have a super high screen-to-body ratio. figure 1 It is a schematic diagram of display screens with different screen ratios in the related art, such as figure 1 As shown, notch screen, water drop screen, digging screen and other technologies have improved the screen-to-body ratio to a certain extent, but in order to obtain a screen-to-body ratio close to 100%, the under-screen camera technology will be the best solution. The under-screen camera is to place the camera under the screen, t...

Abstract

The invention discloses an image processing method and device, a terminal and a storage medium. The method comprises the following steps: acquiring a first image acquired by an in-display camera of aterminal; dividing the first image into at least two image areas; determining minimum brightness values and maximum brightness values corresponding to the at least two image areas to obtain at leasttwo minimum brightness values and at least two maximum brightness values; determining a first parameter value by using the at least two minimum brightness values and the at least two maximum brightness values, wherein the first parameter value represents a brightness change value between the at least two minimum brightness values and the at least two maximum brightness values; and evaluating the quality of the first image by using the first parameter value.

Description

technical field [0001] The present invention relates to terminal technology, in particular to an image processing method, device, terminal and storage medium. Background technique [0002] With the rapid development of mobile terminal technology, users have higher and higher requirements on the screen-to-body ratio of the display screen of the terminal. In order to meet the needs of users, the camera can be set under the display screen to increase the screen-to-body ratio. However, since light will be diffracted when entering the under-screen camera through the display screen, the imaging effect of the under-screen camera will have a certain impact. How to detect the imaging effect of the under-screen camera has become the key. Therefore, it is urgent to find a technical solution for evaluating the imaging quality of the camera under the screen. Contents of the invention [0003] In view of this, the embodiments of the present invention expect to provide an image processi...
