Abstract

The invention discloses a picture blurring method and device and electronic equipment, and belongs to the field of picture processing. The method comprises the steps of obtaining a first picture and a second picture, with the same framing range, taken by the same camera; obtaining depth information according to the first picture and the second picture; determining the background region of the first picture according to the depth information; and blurring the content in the background region of the first picture. Thus, the problem that a user needs to open a picture through software and select the background region in the prior art is solved, the blurring effect is improved, and the user operation is simplified.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image blurring method, device and electronic equipment. Background technique [0002] Background blur is a commonly used photography method, which is well known and used by photography enthusiasts because it can quickly highlight the subject. However, when taking a photo with a blurred background effect, a professional SLR camera must be used and complex adjustment operations can be performed to achieve the desired effect. [0003] In order to meet the needs of non-professional photography users, there is a method for processing images by software means to obtain background blur effects: after taking an image, the user opens the image through image processing software, and uses the image processing software to automatically The tool with the manual box to select the background area. The image processing software performs Gaussian blur of the same or gradient scale on the back...
