Problems solved by technology

[0004] However, due to objective reasons such as different camera resolution requirements and different distance requirements when testing the resolution, it is easy to have problems such as poor correspondence between suppliers and terminal resolution tests, complicated terminal test tools, and difficult unified control. It can be seen that the current camera test Difficulty in normalized management and control

Embodiment Construction

[0025] The technical solution of the present application will be further described below in conjunction with the accompanying drawings and through specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only some structures related to the present application are shown in the drawings but not all structures.

[0026] In the field of camera testing, resolution is also called resolution, resolution, analysis power, resolution, resolution, resolving power, discrimination power or discrimination rate. The test methods of resolution include spatial frequency response (Spatial Frequency Response, SFR), modulation transfer function (Modulation Transfer Function, MTF) and TVline TVline. TVline is one of the most intuitive test methods, with ISO12233 as the standard for analysi...

Abstract

The embodiment of the invention discloses a camera analysis capacity test graphic card. The camera analysis capacity test graphic card comprises a central focusing zone, a first view field radial resolution strip and a first view field tangential resolution strip; the first view field radial resolution strip and the first view field tangential resolution strip are distributed in an arc shape withthe central focusing zone as a circle center, so that multiple resolutions are contained on the same circumference; when cameras with different analysis capacities are measured, resolution interval sections corresponding to different analysis capacities can be detected on the arc without adjusting the positions of the cameras, the normalization of the analysis capacity test is improved, definitiontest correspondence of a supplier and a terminal is improved, the complexity of a test tool is reduced, the difficulty of normalization management and control is simplified, and the test efficiency is improved.

Description

technical field [0001] The embodiment of the present application relates to the technical field of mobile terminal testing, and in particular to a camera resolution testing chart card. Background technique [0002] With the continuous popularization of mobile terminals, the camera has become a standard configuration of the mobile terminal, and almost every mobile terminal is equipped with a camera. The sharpness of the camera, also known as resolution or resolution, is an important parameter that reflects the quality of the camera. Therefore, in the testing phase of the mobile terminal, the camera needs to be tested accordingly. [0003] There are three test methods for resolving power: spatial frequency response (Spatial Frequency Response, SFR), modulation transfer function (Modulation Transfer Function, MTF) and TVline. TVline is one of the most intuitive test methods, with ISO12233 as the standard for analysis. The TVline line pairs in the reading TV line area of ​​th...
