Stray light automatic shooting machine

Abstract

The invention discloses a stray light automatic shooting machine. The stray light automatic shooting machine is characterized in that a transport mechanism is controlled through an electrical control mechanism, and can move a rotation platform mechanism carrying a camera module to be tested and a test tool into or out of a point light source test darkroom so as to perform a point light source test or an area light source test, and the area light source test is usually completed under an external environment. Through cooperation of a first rotation shaft, a first mounting seat and a first motor and cooperation of a second rotation shaft, a second mounting seat and a second motor on the rotation platform mechanism, the two motors are connected from the top down at an angle of 90 degrees to form a multi-angle rotation component, the two motors are rotated at set angles under control of the electrical control mechanism, and therefore test directions and angles of a camera to be tested on a support platform are changed, the test tool drives the camera module to be tested to automatically shoot pictures at each direction and each angle, appearing angles of stray light can be effectively and accurately positioned, a large quantity of human and material resources is saved, and judgment analysis is accurate and effective.

Description

technical field [0001] The invention relates to a camera module testing device, in particular to an automatic shooting machine for stray light. Background technique [0002] What is stray light? When the camera module forms a real image of an object, in addition to imaging rays, there are other non-imaging rays that diffuse on the image surface of the optical system. These non-imaging rays are called stray light, and stray light is also reflected light. Only absolute black bodies in the universe have no reflection Yes, all other things have reflective properties; since there is reflection, it is impossible to eradicate the stray light of the camera module, and it can only be reduced or weakened as much as possible. [0003] At present, to test the stray light of the camera module, the resolution OK module (need to ensure that the external light is OK) is aimed at the surface light source (about 3m away) and the point light source (30cm-60cm). When the light source is locate...

AI Technical Summary

Problems solved by technology

[0004] 1. It is impossible to fully consider all angles. 2. It takes a lot of manpower and material resources to record a large number of pictures. 3. It is impossible to accurately locate the angle of stray light, and the description is vague.
