Abstract

The invention discloses an image processing method and device, and belongs to the technical field of image processing. The image processing method comprises the steps that a first image and a second image are acquired, and the first image and the second image are two images of the same shooting scene captured by a first camera and a second camera of the electronic equipment; determining sparse depth maps of the first camera and the second camera according to the first image and the second image; obtaining a dense depth map of the image of the shooting scene; according to the dense depth map, adjusting the depth of pixel points in the sparse depth map to obtain a target depth map; and according to the target depth map, performing blurring processing on a target image, the target image being one of the first image and the second image.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to an image processing method and device thereof. Background technique [0002] With the rapid development of communication technology, smart electronic devices, such as mobile phones, have become indispensable tools in all aspects of users' lives. Among them, taking pictures has gradually become one of the commonly used functions of mobile phones. Moreover, it is also possible to take photos with background blur effects through mobile phones. [0003] Among them, the realization of virtual shooting based on dual cameras is already a relatively common technology. However, for areas such as sparse textures, repeated textures, dark light, and occlusions, the parallax processing of the dual camera is relatively weak, which makes the depth calculation inaccurate, which in turn leads to blurring or false blurring. [0004] It can be seen that, in the pri...
