Method and device for evaluating anti-shake effect of camera module

Abstract

The invention discloses a camera module anti-shake effect evaluation method and device, and the method comprises the steps: firstly, obtaining images of a test target in a darkroom environment, in a static state, in a state that the camera module shakes in a first direction, and when an anti-shake function is started, and in a state that the camera module shakes in the first direction, and when the anti-shake function is closed; then, respectively carrying out binarization processing on the three images, and determining image areas of a test target in the three images; secondly, respectively calculating the lengths of the image areas of the test target in the three images along the first direction; and finally, based on the length of the image area of the test target in the three images along the first direction, obtaining the jitter suppression ratio of the camera module for evaluating the anti-jitter effect of the camera module, compared with the existing method for evaluating the anti-jitter effect of the camera module based on artificial visual visual feeling, the method is more objective and accurate, and the accuracy of the anti-jitter effect of the camera module is improved. The operation is simpler and more effective.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method and device for evaluating the anti-shake effect of a camera module. Background technique [0002] At present, smart phones have been widely popularized and applied. The camera function is an important function of smart phones. The quality of the camera function has a great subjective impact on users, and the quality of the photos also directly affects the market sales of smart phones. Therefore, mobile phone manufacturers or camera module manufacturers are constantly updating and improving the shooting quality of the camera module. Among them, the anti-shake function of the camera module is a necessary prerequisite for taking high-quality photos. Before the camera module or smartphone leaves the factory, it is usually necessary to evaluate the anti-shake effect of the camera module. The quality of the anti-shake effect evaluation scheme directly affect...

Problems solved by technology

[0003] When evaluating the anti-shake effect of the camera module in the prior art, it is usually based on the artificial visual perception to judge whether the anti-shake effect is good or not, but the evaluation of the anti-shake effect of the camera module based on the artificial visual perception is lack of objective evaluation Therefore, there is an urgent need for an objective, accurate, simple and effective method and device for evaluating the anti-shake effect of camera modules.
