Abstract

The invention provides a blurred photos generation method, blurred photos generation device and a mobile terminal. The blurred photo generation method comprises steps of detecting a contour edge of a shooting subject in a foreground area in a current preview image, obtaining a blurring coefficient for blurring processing on the background area beyond the couture edge in the current preview image, and performing gauss blurring processing on the background area according to the blurring coefficient to generate a blurred photo. The blurred photo generation method can prevent the shooting subject from being blurred or can prevent the background from not being completely blurred and improves blurring accuracy of the photo.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method, device and mobile terminal for generating blurred photos. Background technique [0002] With the continuous development of the mobile terminal technology, the shooting functions in the mobile terminal are becoming more and more abundant. Currently, users can choose to generate a photo with a blurred background during the photo taking process. However, for some special and complex scenes, when generating a blurred photo, there may be a problem that the subject is blurred at the edge of the subject and the background, or the background is not blurred, and the accuracy of the blurring process is low. Contents of the invention [0003] The present invention aims to solve the above-mentioned technical problems at least to a certain extent. [0004] Therefore, the first object of the present invention is to provide a method for generating a blurred photo,...
