IMAGE PROCESSING METHOD, APPARATUS, AND DEVICE
First Claim
1. An image processing method, comprising:
- obtaining a first image of an object photographed by a first camera of a photographing device having the first camera and a second camera, wherein optical axes of the first camera and the second camera are parallel to each other, and a spacing between the first camera and the second camera is less than a preset distance, wherein f-numbers of the first camera and the second camera are less than 1.6, and neither of quantities of lenses of the first camera or the second camera is greater than 6;
obtaining a second image of the object photographed by the second camera;
obtaining a first sub-image of the first image, wherein definition of the first sub-image satisfies a preset definition standard;
obtaining a second sub-image of the second image, wherein definition of the second sub-image satisfies the preset definition standard, there is an image intersection set between the first sub-image and the second sub-image, and an image union set between the first sub-image and the second sub-image can represent the object; and
performing fusion processing on the first sub-image and the second sub-image to obtain a target image.

Abstract
An embodiment of the present invention discloses an image processing method, an apparatus, and a device. The method is applied to a terminal having two specially manufactured cameras. A first sub-image that is of a to-be-photographed object and that is photographed by a first camera is obtained, where a corresponding field-of-view range is [0, θ1]; a second sub-image that is of the to-be-photographed object and that is photographed by a second camera is obtained, where a corresponding field-of-view range is [θ2, θ3], and quality of the first sub-image and the second sub-image satisfies a definition requirement of an extra-large aperture; and the first sub-image and the second sub-image are spliced and fused to obtain a target image that has a larger field-of-view range and satisfies the extra-large aperture.
