Embodiment Construction

[0033] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0034] For example, electronic products such as mobile phones usually include a camera module, and before the camera module is used in a product, it needs to pass a performance test to ensure that the camera module of the electronic device meets the expected shooting requirements.

[0035] Among them, the resolution of the imaging system is one of the key indicators used to evaluate th...

Abstract

The invention relates to a camera performance test card and a camera test system, and the camera performance test card is used in cooperation with a camera module and comprises a plurality of color blocks arranged in an array. The focusing mark arranged at the central position of each color block improves the focusing efficiency of the camera module; due to the fact that the color blocks with the focusing marks are arranged in an array mode, the camera performance test card can use the same algorithm for testing camera modules of different specifications, and simultaneous testing of the camera modules can be achieved. Therefore, the test effect, the compatibility and the test efficiency of the camera performance test card and the camera test system using the camera performance test card are improved.

Description

technical field [0001] The disclosure relates to the field of electronic technology, in particular to a camera performance test card and a camera test system. Background technique [0002] For example, electronic products such as mobile phones usually include a camera module, and before the camera module is used in a product, it needs to pass a performance test to ensure that the camera module of the electronic device meets the expected shooting requirements. [0003] Among them, the resolution of the imaging system is one of the key indicators used to evaluate the performance of the camera module. When testing the resolution of the imaging system, a camera performance test card is required. The camera module to be tested shoots a camera performance test card to obtain a test image, and then analyzes the test image through a corresponding algorithm to judge the resolution of the camera module to be tested. [0004] However, due to the structural limitation of the camera per...
