Abstract

The invention discloses an image processing method and device, and the method comprises the steps: obtaining a to-be-displayed image, carrying out the preprocessing of the to-be-displayed image through an edge detection operator, and obtaining an ROI in the to-be-displayed image; calculating the characteristic parameters of the ROI; obtaining a target mapping function according to the characteristic parameters and a linear regression method; carrying out the adaptive adjustment of the characteristic parameters according to the target mapping function when the characteristic parameters are determined to meet a preset adjustment condition according to the characteristic parameters and the target mapping function, and enabling the to-be-displayed image to be outputted and displayed after adaptive adjustment. The method achieves the adaptive adjustment, and improves the display quality of the image and the user experience.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image processing method and device. Background technique [0002] Due to the many scenarios of mobile phone applications, the display quality of the mobile phone screen has a certain relationship with the environmental factors. For example, the content displayed on the screen can be clearly seen under indoor lighting, but it is difficult for users to see clearly when moved outdoors under strong light. For similar scenarios such as the content displayed on the screen, if the user wants to see clearly the content displayed on the screen in different scenarios, he needs to manually adjust it. It can be seen that the constant brightness of the mobile phone screen is not suitable for the use of the mobile phone in different scenarios. [0003] At present, Content Adaptive Backlight Control (English full name: Content Adaptive Backlight Control, English abbreviation: CABC) te...
