Abstract

The invention is to provide a mobile phone camera module white balance detection method, which is characterized by, to begin with, adjusting parameters of a camera module to optimum; then, adjusting a mobile phone to be in an automatic mode; enabling the mobile phone to directly face a 24 color card; then, carrying out shooting after irradiation of a D65 light source, a TL84 light source, an A light source and a CWF light source in sequence; and finally, analyzing a white balance value of the shot images, so that mobile phone camera white balance detection can be carried out very well, and the detection effect is excellent.

Description

technical field [0001] The invention relates to the detection field of mobile phone cameras, in particular to a white balance detection method of a mobile phone camera module. Background technique [0002] With the continuous development of science and technology, the function of the camera of the mobile phone is more and more important. There is a camera module in the mobile phone, and the camera module of the mobile phone is assembled from parts. After the camera module is produced, various tests must be carried out on it, and the test can only be delivered if it meets the standard. One of the tests is the white balance test. The current test for white balance is not perfect, so it is very necessary to solve this problem. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for detecting white balance of the camera module of a mobile phone. By first adjusting the parameters of the camera module to the best, the...
