Title:

DEPTH OF FIELD OBTAINING METHOD, APPARATUS AND DEVICE

Document Type and Number:

WIPO Patent Application WO/2019/105260

Kind Code:

A1

Abstract:

The present invention provides a depth of field obtaining method, apparatus and device. The method comprises: obtaining multiple main image frames captured by a main camera and multiple auxiliary image frames captured by an auxiliary camera, and obtaining a main reference image having the highest sharpness according to the sharpness of each main image frame and each auxiliary image frame; comparing the sharpness of main images other than the main reference image and the sharpness of each auxiliary image frame with the sharpness of the main reference image to detect whether candidate main images and candidate auxiliary images that satisfy a preset screening threshold exist; if yes, obtaining image information of the main reference image, each candidate main image frame, and each candidate auxiliary image frame to determine a first target main image and a first target auxiliary image; and obtaining depth of field information according to the first target main image and the first target auxiliary image. Hence, the quality and consistency of images from which depth of field information is obtained are ensured, and the precision of the depth of field and imaging effect are improved.
