Title:
BACKGROUND BLURRING METHOD AND APPARATUS, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/105261
Kind Code:
A1
Abstract:
Disclosed in the present application are a background blurring method and apparatus, and a device. The method comprises: obtaining a main image captured by a main camera and an auxiliary image captured by an auxiliary camera, and obtaining depth of field information of the main image according to the main image and the auxiliary image; determining original blurring intensities of different subregions in a background region of the main image according to the depth of field information and a focus region; determining distribution orientations of the different subregions according to a display mode of the main image, and determining blurring weights of the different subregions according to a weight setting strategy corresponding to the distribution orientations; determining target blurring intensities of the different subregions according to the original blurring intensities and the corresponding blurring weights of the different subregions; and blurring the background region of the main image according to the target blurring intensities of the different subregions. Therefore, the blurring effect is more natural, and more approaches to a real optical defocusing effect.
