Problems solved by technology

[0004] Usually, a camera module includes components such as a lens module and a lens holder. When the camera module is assembled on an electronic device, the position of the lens module of the camera module in the mirror holder will change due to the extrusion of the housing of the electronic device. Offset, which eventually causes the resolution of the camera module to be seriously attenuated

Abstract

The invention discloses a camera module testing method, a camera module testing device and a computer readable storage medium, wherein the camera module testing method comprises the steps of: respectively performing resolution power testing of imaging points of N pre-set positions in a current test image; continuously applying pre-set pressure on the lens and / or the holder of a camera assembly in a resolution power testing process; adjusting the position of the lens in the holder, and returning to the resolution power testing step and the subsequent step till the target position of the lens in the holder is searched, wherein when the lens is at the target position in the holder, the resolution power testing value of the imaging point at the pre-set position in the N pre-set positions is maximum; and fixing the lens at the target position in the holder when the target position is searched. By means of the technical scheme provided by the invention, the resolution power attenuation degree of a camera module after being assembled on electronic equipment can be effectively reduced.

Description

technical field [0001] The present invention relates to the field of camera technology, in particular to a camera module testing method, device and computer-readable storage medium. Background technique [0002] With the rapid development of intelligence in the electronic technology industry, the camera system used to acquire image and video information, as the carrier of human visual extension, has gradually become a core device and is widely used in various electronic devices. [0003] At present, more and more electronic devices are beginning to develop in the direction of miniaturization, miniaturization and high image quality. Based on this trend, camera devices are also miniaturized into camera modules to be installed in electronic devices. [0004] Usually, a camera module includes components such as a lens module and a lens holder. When the camera module is assembled on an electronic device, the position of the lens module of the camera module in the mirror holder wi...
