Abstract

The invention provides a zoom blurred image acquisition method and device based on terminal equipment, and the method comprises the steps: obtaining a zoom photographing instruction carrying a zoom multiple; judging the size relationship between the zoom multiple and the equivalent zoom multiple of the main camera and the at least one auxiliary camera; according to the size relationship, determining a zoom main camera and a zoom auxiliary camera in the main camera and the at least one auxiliary camera, and determining a photographing mode of the zoom main camera in a preset photographing mode;controlling the zoom main camera to shoot a main image according to the shooting mode, and controlling the zoom auxiliary camera to shoot an auxiliary image; cutting the main image according to the zoom multiple to obtain a zoom main image, and blurring the zoom main image according to the auxiliary image to obtain a blurred main image; and performing background blurring rendering on the zoomingmain image according to the blurring main image to generate a zooming blurring image. The shooting requirements of multiple zoom multiples during shooting of multiple cameras are flexibly met, and theimaging definition after zooming is ensured.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for acquiring a zoom blurred image based on a terminal device. Background technique [0002] With the popularization of terminal devices, the camera functions of terminal devices are becoming more and more diversified. For example, dual cameras are used to realize zooming in portrait mode, which can meet the needs of users for taking pictures of portraits. [0003] In related technologies, the dual cameras of the terminal equipment are fixed-focus cameras, which cannot support flexible zooming in portrait mode, which leads to the adjustment of the size of the photographed portrait only by the movement of the photographer during the portrait photographing process. Therefore, there is an urgent need A camera method that flexibly meets the zoom requirements when taking pictures with multiple cameras. Contents of the invention [0004] The pres...
