Camera module and acquisition method and adjustment method of image plane inclination of camera module

Abstract

The invention discloses a camera module and an acquisition method and adjustment method of an inclined image plane of the camera module. The acquisition method includes the following steps: judging whether interpolation operation is needed when acquiring image plane inclination of the camera module; shooting a test pattern of a stereoscopic chart through the camera module, so as to obtain resolution data of the camera module; and acquiring the image plane inclination of the camera module according to the resolution data of the camera module. In this way, the acquisition method can improve the accuracy and efficiency of testing the image plane inclination of the camera module.

Description

technical field [0001] The invention relates to the field of optical imaging, in particular to a camera module and a method for acquiring and adjusting the inclination of its image plane. Background technique [0002] In recent years, the camera module used to help users acquire images (such as video or images) has gradually become a standard configuration of electronic devices (such as mobile electronic devices, such as mobile phones). , industrial production and other fields have also been widely promoted and applied. In this context, users have higher and higher requirements for the imaging quality of camera modules. This market demand not only requires camera module manufacturers to provide camera modules with higher pixels, but also gives camera modules The manufacturing process puts forward higher and more stringent requirements. [0003] The camera module mainly includes a photosensitive chip and an optical lens. The optical lens is set on the photosensitive path of...

Problems solved by technology

Simply relying on the scene depth information provided by the camera module to fit the defocus curve, on the one hand, the accuracy of the camera module in the process of fitting the defocus curve is limited by the stereo standard, so that it causes The mutual restriction between standard plate design and fitting defocus curve accuracy, on the other hand, also leads to inefficiency of camera module fitting defocus curve and calculating image plane tilt, which is not in line with the development trend of camera module industry
