Abstract
Devices, methods, and non-transitory program storage devices are disclosed to provide optical image stabilization (OIS) systems having a control mode with per-image frame recentering. Due to the mechanical limits of OIS systems' movement stroke, OIS systems are typically limited to being able compensate for no more than a few degrees of camera device rotation. If the device rotation motion is larger than the OIS movement stroke, the OIS movement becomes saturated, and the OIS is not able to compensate for the device's rotation motion anymore, which could generate image blurring. In order to handle relatively large device rotation motion and increase the exposure time for video capture under low-light scene conditions, it is desirable to utilize the limited OIS stroke more efficiently. This disclosure proposes new ideas for OIS systems that opportunistically re-center themselves over a time duration at the beginning of each video image frame to reduce image blurring.
