Method for self-adaptively evaluating anti-shake function of mobile phone

Abstract

The invention discloses a method for self-adaptively evaluating an anti-shake function of a mobile phone, which comprises the following steps of: 1, fixing the position of the mobile phone, starting avibration table, and shooting an image when the anti-shake function is started or closed; 2, automatically judging a to-be-used evaluation strategy according to the shot image; 3, calculating mobilephone anti-shake function evaluation parameters based on the image blur amount and the image target displacement amount; and 4, generating a mobile phone anti-shake function evaluation report according to a calculation result. According to the method, the anti-shake functions of various types of mobile phones with anti-shake functions are objectively evaluated in a self-adaptive manner; accordingto the mobile phone anti-shake function evaluation method and device, the defect that an existing mobile phone anti-shake evaluation process is single is overcome, the actual evaluation requirement ismet, the accuracy and effectiveness of the mobile phone anti-shake function evaluation result are improved, the evaluation result is more reasonable and more accurate, and transverse comparison of anti-shake functions between mobile phones is easier to achieve.

Description

technical field [0001] The invention relates to an evaluation method, in particular to an evaluation method capable of adaptively adjusting different types of mobile phone anti-shake functions, and belongs to the field of mobile phone evaluation. Background technique [0002] The camera function is an important part of smart phones, and its shooting quality directly affects the sales of smart phones. Therefore, manufacturers are constantly updating and improving the shooting quality of mobile phones in order to perfectly show the camera effect and enhance the competition of mobile phones. force. [0003] The anti-shake function of mobile phones is a necessary prerequisite for taking high-quality photos, especially for smart phones, its functions and functions are more prominent and obvious. [0004] The current evaluation process for the anti-shake function of mobile phones mainly includes: [0005] 1) Place the mobile phone on the vibrating table, change the Shutter Spe...

Problems solved by technology

[0016] 1) The content of the standard focuses on the description of the evaluation operation process, and the definition of the calculation part of the evaluation result is not clear enough, and there is ambiguity, which leads to different evaluation results obtained by users using different calculation methods in the actual use process;

[0017] 2) The evaluation method described in the standard is only for mobile phones that use optical image stabilization, and the evaluation object is the amount of blur in the captured picture, which reduces the universality of the evaluation method. Some smart phones that use electronic image stabilization, digital image stabilization, etc. Effective evaluation cannot be carried out, which has a serious impact on the actual evaluation process;

[0018] 3) The standard evaluation results are anti-shake levels, such as level 1, level 3, etc., which are too general, and non-professionals cannot correctly interpret the results, which will affect users' judgment on mobile phone anti-shake performance
