Combined mechanical and electronic image stabilization

A method comprising:

• determining a sequence of orientation estimates based on sensor data from one or more motion sensors;
• based on the sequence of orientation estimates, invoking a mechanical stabilization system to reject motions of an image sensor occurring within a first operating bandwidth with an upper cutoff frequency;
• receiving an image from the image sensor;
• based on the sequence of orientation estimates, invoking an electronic image stabilization module to correct the image for rotations of the image sensor occurring within a second operating bandwidth with a lower cutoff frequency to obtain a stabilized image, wherein the lower cutoff frequency is greater than the upper cutoff frequency;
• and
• storing, displaying, or transmitting an output image based on the stabilized image.

A system comprising:

• an image sensor configured to capture an image;
• a mechanical stabilization system, including motors, configured to control an orientation of the image sensor to reject motions occurring within a first operating bandwidth with an upper cutoff frequency;
• and
• an electronic image stabilization module configured to correct images for rotations of the image sensor occurring within a second operating bandwidth with a lower cutoff frequency to obtain a stabilized image, wherein the lower cutoff frequency is greater than the upper cutoff frequency.
