Problems solved by technology

[0003] Because the test is a multi-station test, the test time is prolonged and the test efficiency is greatly reduced, especially when a certain test station is occupied
Moreover, when taking test photos at the ISO test station, it is necessary to adjust the shooting device many times, and the adjustment of the device is extremely time-consuming, especially for new operators
In addition, the test requires a strict light source, and the test light source used in the current test is not very strict

Abstract

The invention provides a one-stop image testing device, and the device is used for the image testing of a cellphone camera module. The device comprises a testing image card attaching plate, a guide rail, and guide rail connecting rods. The guide rail is divided into an upper part and a lower part, and the left and right sides of the guide rail are respectively provided with one guide rail connecting rod, so as to support the upper and lower parts. The testing image card attaching plate is slidingly disposed between the upper and lower parts of the guide rail, and is used for pasting a testing image card.

Description

technical field [0001] The invention relates to image testing technology, in particular to a one-stop image testing device applied to a camera module of a mobile phone. Background technique [0002] Currently in the industry, the image test of the Cell-phone Camera Module (CCM) is a multi-station test, and a test photo needs to be taken at each test station, and compared with different test charts, in order to Test whether the different index parameters of the mobile phone camera module are up to standard. For example, currently commonly used test charts include ISO12233 test charts, geometric distortion test charts, film distortion (also known as uniformity) test charts, 24-color charts, and Kodak grayscale charts. Among them, the ISO test station using the ISO12233 test chart needs to adjust the shooting device when taking the test photos so that the 4:3 area just falls on such Figure 1A In the preview screen shown by the dotted border in the middle; then move the camera...
