Abstract

The invention provides an image obtaining method and an image obtaining device. The method and the device can realize multi-focus shooting and processing on shooting subjects with different depths of field, and images with a high clear degree are obtained. The method provided by the invention comprises the following steps that: a plurality of regions to be focused are recorded according to received selection instructions of the regions to be focused; each region to be focused is subjected to focal plane contrast ratio calculation; then, automatic focusing is carried out according to the focal plane contrast ratio, and a plurality of focal lengths to be focused are obtained; shooting is performed by referring to the plurality of focal lengths to be focused, and a plurality of shot images are obtained; each shot image is divided into a plurality of sub images in the same meshing mode; the plurality of sub images corresponding to each mesh region are subjected to sub image contrast ratio calculation; for the plurality of sub images corresponding to the same mesh region, the sub image with the highest sub image contrast ratio is selected to be used as a fusion sub image corresponding to the mesh region; and the fusion sub images corresponding to all mesh regions are spliced, and a fusion result image is obtained.

Description

technical field [0001] The present invention relates to the field of computer vision, in particular to a method and device for acquiring images. Background technique [0002] In the process of taking pictures, the existing mobile phones can usually only take one scene at a time, form one image, and have only one focal length value. When it is necessary to take a group photo of multiple rows of people, or when it is necessary to shoot buildings / landscapes with obvious layers, there must be some people or objects that are not on the focal plane, so that these people or objects with different depths of field cannot be on the same focal plane The image is clearly imaged on the camera, but the quality of the photos taken is not high. Contents of the invention [0003] In view of this, the present invention provides a method and device for acquiring images, which can perform multi-focus shooting and processing on shooting objects with different depths of field to obtain high-qu...
