specific example

[0069] The tester can pre-set the method provided by this embodiment as software, and after starting the software, manually input or read the pre-stored first exposure register value and second exposure register value (or input the first exposure duration or the second exposure duration) , and input or read the range of the three primary color channels of the fourth image. The software operates in an environment with a color temperature of 5000K±200K and an illumination of 500±50Lux under the G4C light source, and automatically calculates the third exposure register value and the fourth exposure register value according to the method provided in this application, and automatically runs to obtain the corresponding first image , the second image, the third image and the fourth image, a total of four raw images.

[0070] Through the method of this embodiment, four raw images can be automatically calculated and obtained, avoiding manual adjustment of the exposure register to take ...

Abstract

The invention discloses a debugging method, device, equipment and medium for a camera module. The method includes: acquiring a first exposure register value and a second exposure register value, and obtaining a second image by shooting with the second exposure register value; Determine the three primary color channel parameters of the second image according to the three primary color algorithm, and determine the third exposure register value according to the preset correlation requirements according to the three primary color channel parameters and the exposure algorithm; determine according to the exposure algorithm and the preset three primary color channel ranges. Outputting the fourth exposure register value; generating debugging data for debugging the camera module according to the first image, the second image, the third image and the fourth image. The debugging method, device, equipment and medium provided by the invention are used to solve the time-consuming and labor-consuming technical problems existing in the existing debugging methods. The technical effect of improving efficiency is realized.

Description

technical field [0001] The invention relates to the technical field of camera module processing, in particular to a camera module debugging method, device, equipment and medium. Background technique [0002] Before the camera module is shipped, in order to ensure the actual shooting effect, it often needs to be debugged. Specifically, it is necessary to analyze the image captured by the camera module to obtain the debugging data, and then adjust the basic initial parameters of the camera module according to the debugging data, so that the factory camera module has a better shooting effect. [0003] In order to obtain accurate debugging data, it is often necessary to take multiple images, and to ensure the accuracy of the debugging data, it is often required that the multiple images have different image parameters, such as brightness. At present, the method of selecting these multiple images is often to first manually adjust the exposure register to take multiple images, and...
