Auto focus and optical image stabilization with roll compensation in a compact folded camera
First Claim
1. A folded camera module comprising:
- a) an optical path folding element (OPFE) for folding light from a first optical path with a first optical axis to a second optical path with a second optical axis perpendicular to the first optical axis; and
b) a lens module carrying a lens with a symmetry axis parallel to the second optical axis,wherein the OPFE is designed to tilt and wherein the lens module is designed to move such that the OPFE tilt and the lens module movement cooperatively provide optical image stabilization (OIS) that compensates for roll of the folded camera module in addition to compensation for pitch and yaw movements of the folded camera module.

Abstract
Folded digital camera module comprising an optical path folding element (OPFE) for folding light from a first optical path with a first optical axis to a second optical path with a second optical axis perpendicular to the first optical axis, an image sensor, and a lens module carrying a lens with a symmetry axis parallel to the second optical axis. The camera module is adapted to perform optical image stabilization (OIS) involving at least one tilt motion of the OPFE tilt around an axis such that the OPFE tilt creates an image Roll movement and a shift movement, the OPFE tilt-created image Roll movement compensating for a folded camera module-induced Roll movement and the shift movement cancelable by a movement of the lens module.

11. A method of providing optical image stabilization in a folded camera module that includes an optical path folding element (OPFE) for folding light from a first optical path with a first optical axis to a second optical path with a second optical axis perpendicular to the first optical axis and a lens module carrying a lens with a symmetry axis parallel to the second optical axis, the method comprising:
tilting the OPFE and moving the lens module cooperatively to provide optical image stabilization (OIS) that compensates for roll of the folded camera module in addition to compensation for pitch and yaw movements of the folded camera module. - View Dependent Claims (12, 13, 14)
