Problems solved by technology

Since the brightness of the screen of the mobile phone is fixed, these methods of adjusting the brightness of the picture are only reflected in the photo in the end, and the effect of adjusting the picture by the camera cannot be reflected to the user on the display screen in real time, resulting in even if the camera module of the mobile phone increases the brightness of the dark area, However, the brightness of the display screen of the mobile phone is still very dark, and the adjustment effect of the image processing module on the image cannot be seen in real time, or the display screen of the mobile phone is very bright, and the image processing module suppresses the overexposure effect of the image, but the image displayed on the display screen of the mobile phone The real-time images are still overexposed, seriously affecting the user experience

Abstract

The invention discloses a device and method for adjusting brightness of a display screen. The method of adjusting the brightness of the display screen comprises the steps of S1, calculating a first relationship between a brightness value of an image and a brightness value of the display screen when the image is normally displayed, S2, dividing the image which is obtained by previewing into a plurality of regions, S3, calculating and obtaining a first brightness value of each region, S4, judging whether or not the image needs image processing, if the image needs image processing, carrying out the image processing, S5, calculating and obtaining a second relationship of the first brightness value and a second brightness value of a processed image, and S6, adjusting a display brightness of the display screen according to the first relationship and the second relationship. The device and method for adjusting the brightness of the display screen can adjust the brightness of the display screen in real time according to brightness information of a picture taken by a user, and finally presents the best picture effect to the user, greatly improving the user experience.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a device and method for adjusting the brightness of a display screen.
