THREE-AXIS OIS FOR SUPER-RESOLUTION IMAGING

摘要

Systems and methods are provided for super-resolution imaging using 3-axis OIS. A super-resolution image may be created by enabling optical image stabilization (OIS) in three axes using an OIS system on a camera of an image capturing device; capturing an image of a scene using an image sensor of the camera; shifting the image on the image sensor by a predetermined subpixel amount; capturing the subpixel shifted image; and constructing a super-resolution image of the scene using the image and the subpixel shifted image. In one particular implementation, a position sensor may measure a positional drift of the image sensor after capturing the image. Using this measured positional drift, a time sufficient to shift the image sensor by a predetermined subpixel amount may be determined. The OIS may subsequently be disabled in one or two axes for the determined time.

1. A method, comprising:
enabling optical image stabilization (OIS) in three axes using an OIS system on a camera of an image capturing device, wherein the 3-axis OIS stabilizes an image on the image sensor of the camera by moving the image sensor in three degrees of freedom; capturing an image of a scene using an image sensor of the camera; shifting the image on the image sensor by a predetermined subpixel amount; capturing the subpixel shifted image; and constructing a super-resolution image of the scene using the image and the subpixel shifted image, wherein the OIS is enabled in three axes when the image and the sub-pixel shifted image are captured.
