Patent ID: 10412306

Abstract:
Disclosed are systems, devices, and methods for compensating for roll blur in an optical image stabilization (OIS) module. An OIS controller receives a selection for one or more areas of interest (AOI), each AOI associated with an image optimization point (IOP), and each IOP is associated with an X position (Xpos) and a Y position (Ypos). The OIS controller receives gyroscope data comprising X axis rotation data (Xgyro), Y axis rotation data (Ygyro) and Z axis rotation data (Zgyro). The OIS controller generates adjusted X axis rotation data (Xgyro_adj) and Y axis rotation data (Ygyro_adj), wherein Xgyro_adj and Ygyro_adj based on the Z axis rotation data and the one or more IOPs and adjusts lens shift gain on the basis of Xgyro_adj and Ygyro_adj and adjusts lens movement based at least in part on the lens shift gain.
