Description

Technical Field

[0001] The utility model relates to the technical field of camera testing, in particular to an OIS testing device. Background Art

[0002] Camera modules are important electronic devices for image capture. Smart phones, smart cars, robots and other smart terminals need to use camera modules to complete optical imaging and realize functions such as photo taking, information capture and analysis, and visual interaction, resulting in a substantial increase in the demand for cameras.

[0003] After camera modules are produced, they need to be tested to determine if they are qualified. OIS, short for Optical Image Stabilization, literally means stabilizing optical images. Correcting "optical axis offset" is done through a floating lens in the lens. The principle is that the gyroscope inside the lens detects tiny movements and transmits the signal to the microprocessor, which immediately calculates the amount of displacement that needs to be compensated. The compensation lens group then compensates for the lens's shaking direction and displacement, effectively overcoming image blur caused by camera vibration. Before using a camera module, its OIS needs to be tested. Currently, OIS testing is mainly performed using artificial shaking, which has drawbacks such as inconvenient operation, difficulty in data collection, and low efficiency. Utility Model Content
