Imaging difference detection method and apparatus

Abstract

The invention discloses an imaging difference detection method. The method comprises the following steps: respectively obtaining a first image and a second image which are captured by a first camera and a second camera; and comparing imaging quality differences between the first image and the second image, and when the imaging quality differences exceed a preset threshold, sending a prompt to a user. The invention also discloses an imaging difference detection apparatus.

Description

technical field [0001] The present invention relates to terminal imaging technology, in particular to an imaging difference detection method and device. Background technique [0002] At present, more and more mobile terminals adopt dual-camera solutions to realize functions such as quick focus, background blur, and panoramic depth photography. [0003] Whether it is fast focus or large aperture function, it is required that the image quality and other indicators captured by the two cameras of the mobile terminal should be as close as possible; the closer the image quality of the images captured by the two cameras, the better the focus accuracy and background blur effects more excellent. However, in actual use, based on the difference in the installation positions of the dual cameras, one of the cameras is often in a relatively easy-to-touch or occluded position; When the lens is blocked or covered by foreign objects, the image quality difference between the two cameras wil...

Problems solved by technology

[0004] It is relatively simple to identify a large area of ​​occlusion, because after a large area of ​​occlusion, the exposure will be significantly different, and it is easy to judge the occlusion through the exposure difference, and then prompt the user to check and avoid blocking the camera; however, there is currently no effective way to identify A small portion of occlusion and foreign object coverage on the camera
