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...
