Three-axis OIS for super-resolution imaging

A method, comprising:

• 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;
• using one or more position sensors to measure a positional drift of the image sensor after capturing the image;
• shifting the image on the image sensor by a predetermined subpixel amount by:
• determining a time sufficient to shift the image sensor by the predetermined subpixel amount based on the measured positional drift of the image sensor;
• and
• deactivating the OIS in one or two axes for the determined time;
• 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.

An image capturing device, comprising:

• a camera comprising an image sensor and an OIS system for enabling 3-axis 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;
• one or more processors;
• and
• one or more non-transitory computer-readable mediums operatively coupled to at least one of the one or more processors and having instructions stored thereon that, when executed by at least one of the one or more processors, cause at least one of the one or more processors to:
• capturing an image of a scene using the camera;
• shift the image on the image sensor by a predetermined subpixel amount;
• capturing the subpixel shifted image using the camera;
• and
• construct 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.

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 or by moving a lens of the camera in three degrees of freedom;
• causing deformation of a lens of the camera to optimize a point-spread function (PSF) over a specific area of the camera lens;
• and
• digitally zooming in to a scene in the area of the camera lens corresponding to the optimized PSF;
• and
• constructing a super-resolution image of the scene by sampling the scene a plurality of times, wherein the OIS is enabled in three axes each time the scene is sampled.
