| 20080231714 | System and method for capturing images - System and method for capturing images with reduced blur. An embodiment includes an image sensor to capture optical information, a shutter coupled to the image sensor, a motion sensor to measure movement of an electronic device, and a processor coupled to the image sensor, to the shutter, and to the motion sensor. The shutter initiates a capturing of optical information, and the processor controls a state of the shutter based on predicted future movements of the electronic device based on movement information from the motion sensor. The predicted future movements permit a determination of image capture time to reduce blur. | 09-25-2008 |

| 20100208086 | REDUCED-MEMORY VIDEO STABILIZATION - A system and method for performing video stabilization in a reduced memory video device. In one embodiment, a system includes a frame memory and a video stabilizer. The frame memory stores a first video frame and a second video frame acquired after the first video frame. The video stabilizer determines a motion vector indicative of movement of the system between acquisition of the first and second video frames. The determination is based, at least in part, on the first video frame. A number of pixels stored for the second video frame is greater than a number of pixels stored for the first video frame. | 08-19-2010 |
