Image stabilization with adaptive shutter control
First Claim
1. An apparatus to facilitate image stabilization with adaptive shutter control, the apparatus comprising:
- an image sensor to obtain image data;
a movement detector coupled to the image sensor, the movement detector configured to obtain movement measurement information during a shutter period having a predetermined duration; and
a shutter controller coupled to the movement detector, the shutter controller configured to adjust the shutter period of a shutter based on the movement measurement information, wherein the shutter controls a time the image sensor is responsive to light incident on the image sensor by deactivating the shutter in response to a determination that the image sensor moves beyond a movement threshold and reactivating the shutter in response to a determination that the image sensor returns within the movement threshold.

Abstract
An apparatus to facilitate image stabilization with adaptive shutter control is described. An embodiment of the apparatus includes an image sensor, a movement detector, and a shutter controller. The movement detector is coupled to the image sensor. The shutter controller is coupled to the movement detector. The image sensor is configured to obtain image data. The movement detector is configured to obtain movement measurement information during a shutter period having a predetermined duration. The shutter controller is configured to adjust the shutter period of a shutter based on the movement measurement information. The shutter controls the time the image sensor is responsive to light incident on the image sensor. Embodiments of the apparatus provide a smaller and less costly implementation for image stabilization.
