Image processing method, apparatus and equipment

Abstract

The invention discloses an image processing method, apparatus and equipment. The image processing method is applied to a terminal with two specifically manufactured cameras, wherein the first camera and the second camera are customized especially so as to sacrifice the definition of images in the local visual field angle range as the cost; and a super large aperture is realized through the current technology, so that the taken images of a part of areas can satisfy the quality demand of the super large aperture. The image processing method includes the steps: acquiring the first sub image of an object to be taken by the first camera, wherein the corresponding visual field angle range is [0, theta1]; acquiring the second sub image of the object to be taken by the second camera, wherein the corresponding visual field angle range is [theta2, theta3] and the quality of the first sub image and the quality of the second sub image can satisfy the definition demand of the super large aperture; and splicing and fusing the first sub image with the second sub image to obtain a target image satisfying the super large aperture in a greater visual field angle range.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to an image processing method, device and equipment. Background technique [0002] Aperture value (FNO) = focal length / entrance pupil diameter, which is a system parameter of the shooting lens and determines the amount of light entering the lens. The smaller the FNO value, the larger the aperture and the more light entering; on the contrary, the larger the FNO value, the greater the aperture. The smaller it is, the less light it takes in. At the same time, the aperture also determines the limit resolution of the lens, the larger the aperture, the higher the resolution, conversely, the smaller the aperture, the lower the resolution. The aperture value of the lens is directly related to the quality of the photo, such as illumination, resolution, and dark environment imaging capabilities. [0003] Therefore, in order to obtain better photo quality and user experience, the d...

AI Technical Summary

Problems solved by technology

For large aperture (FNO less than or equal to 1.6) lenses, based on the current technical level, the yield rate of manufacturing is very low and the cost is high, which is not conducive to its integration into portable terminal devices such as mobile phones and tablet computers.
