Abstract

The invention provides a method and devices used for image processing. The method and the devices are used in the field of image processing. The method includes: acquiring a first two-dimensional image and focusing information of the first two-dimensional image, acquiring depth information of part or all of a photographed scene in the first two-dimensional image, determining a background area of the first two-dimensional image according to the focusing information, and blurring the background area of the first two-dimensional image according to the depth information. According to the above method, hardware requirements for photographing can be reduced while background blurring is realized, operation is simple, and a background can be quickly blurred.

Description

technical field [0001] The present invention relates to an image processing method and device, in particular to a method and device for blurring the background of an image. Background technique [0002] In daily life, when taking images including videos or still pictures, it is often encountered that the background is cluttered or the background does not want to appear. By blurring the background of the image and making it a blurred background, it can highlight the subject, make the subject more distinct, and produce a better picture effect. [0003] In the prior art, digital cameras can use hardware facilities such as large aperture and large zoom to realize background blurring. Digital cameras usually use the following four methods to blur the background: 1. Make the zoom ratio, that is, the focal length, as large as possible; 2. The distance between the subject and the background in the scene to be photographed is as far as possible; 3. The distance between the lens and ...
