Embodiment 1

[0042] This embodiment provides a method for testing the anti-shake effect, please refer to figure 2 , figure 2 It is a flow chart of the anti-shake effect testing method in the embodiment of the present invention, including:

[0043] Step S201, in the vibrating state, the camera module turns on the anti-shake function and captures N opened test pictures of the test target; N is an integer greater than 1;

[0044] Step S202, in the vibration state, the camera module turns off the anti-shake function and captures M closed test pictures of the test target; M is an integer greater than 1;

[0045] Step S203, comparing the imaging position of the test object in the N open test images with the imaging position of the test object in the M closed test images to determine the anti-shake effect.

[0046] It should be noted that the execution order of step S201 and step S202 is not limited, step S201 may be executed first, and step S202 may also be executed first.

[0047] Below, c...

Embodiment 2

[0075] like Figure 4 As shown, an anti-shake effect test device is provided, including:

[0076] The opening module 401 is used to enable the camera module to open the anti-shake function and capture N pieces of open test charts of the test target under the vibration state; N is an integer greater than 1;

[0077] Closing module 402, for under vibrating state, camera module closes anti-shake function and photographs and obtains M pieces of closed test charts of said test target; M is an integer greater than 1;

[0078] The comparison module 403 is configured to compare the imaging position of the test target in the N open test pictures with the imaging position of the test target in the M closed test pictures to determine the anti-shake effect.

[0079] In the embodiment of the present application, the anti-shake effect test device may be a camera module, a computer, a dedicated tester or a test device integrated into a production line, which is not limited here.

Embodiment 3

[0083] like Figure 5As shown, the present embodiment provides an electronic device, including a memory 510, a processor 520, and a computer program 511 stored on the memory 510 and operable on the processor 520. When the processor 520 executes the computer program 511 Implement the following steps:

[0084] In the vibration state, the camera module turns on the anti-shake function and takes N pieces of open test pictures of the test target; N is an integer greater than 1;

[0085] In the vibrating state, the camera module closes the anti-shake function and captures and obtains M pieces of closed test diagrams of the test target; M is an integer greater than 1;

[0086] Comparing the imaging position of the test target in the N open test pictures with the imaging position of the test target in the M closed test pictures to determine the anti-shake effect.

[0087] In this embodiment of the present invention, when the processor 520 executes the computer program 511, any imple...

Abstract

The invention discloses an anti-shake effect test method and device, electronic equipment and a medium, and the method comprises the steps: enabling a camera module to start an anti-shake function ina vibration state, and carrying out the photographing of N start test graphs of a test target, wherein N is an integer greater than 1; in the vibration state, enabling the camera module to close the anti-shake function and shoots to obtain M closing test pictures of the test target, wherein M is an integer greater than 1; and comparing the imaging positions of the test targets in the N opening test images with the imaging positions of the test targets in the M closing test images to determine an anti-shake effect. The method, the device, the electronic equipment and the medium provided by theinvention are used for solving the technical problem of inaccurate anti-shake effect of a long exposure test in the prior art, and realize the technical effect of improving the anti-shake effect testaccuracy.

Description

technical field [0001] The invention relates to the technical field of camera modules, in particular to a method, device, electronic equipment and medium for testing the anti-shake effect. Background technique [0002] Before the camera module leaves the factory, a performance test is often required, and the effect test of Optical Image Stabilization (OIS) is one of the important performance tests. [0003] The current optical anti-shake effect test method in the industry mainly adopts the long-exposure detection method, that is, long-exposure is used to obtain a test chart when the camera module is shaken, and the anti-shake effect is evaluated by analyzing the long-exposure test chart. However, problems such as "afterimage" caused by long exposure will seriously affect the accuracy of the analysis of the test chart, resulting in technical problems of poor test accuracy. Contents of the invention [0004] In view of the above problems, the present invention is proposed t...
