Abstract

The invention discloses a preview image processing method based on a mobile terminal. The mobile terminal includes a first camera and a second camera. The method includes: setting the first camera and the second camera to different Focus mode; acquire the first preview image and the second preview image respectively collected by the first camera and the second camera in different focus modes; background the first preview image and the second preview image Blur processing to generate the target image. The invention also provides a corresponding mobile terminal. The mobile terminal-based preview image processing method provided by the present invention can obtain images of the same picture at different focal lengths during preview, thereby realizing the real-time preview of images with background blur effects, and solving the problem that background blur can only be realized when taking pictures. The effect of customization, but cannot realize the problem of what you see is what you get when previewing.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of image processing, and in particular to a mobile terminal-based preview image processing method and the mobile terminal. Background technique [0002] Due to the limitation of the hardware of smart phones, it is difficult to take photos with background blur effect, that is, photos with clearer subjects and blurred backgrounds. The current method for realizing the background blur effect is generally to process and synthesize multiple pictures with different focal lengths. For example, take a picture with the focal length on the subject, and then take a picture with the focal length at infinity, and finally synthesize a picture with a background blur effect after being processed by the blurring algorithm. [0003] It can be seen that in the existing photographing technology, the background blur effect can only be realized when taking pictures, and the real-time background blur effe...
