Abstract

A video device includes a first video camera, a second video camera, a motion estimating portion and an image stabilization portion. The first video camera records a first image of a first field of view, records a second image of the first field of view, outputs a first frame of image data based on the first image and outputs a second frame of image data based on the second image. The second video camera records a third image of a second field of view, records a fourth image of the second field of view, outputs a third frame of image data based on the third image and outputs a fourth frame of image data based on the fourth image. The motion estimating portion outputs a motion signal based the fourth frame of image data. The image stabilization portion modifies the second frame of image data based on the motion signal.

wherein said outputting, via the second video camera, a third frame of image data based on the third image comprises outputting the third frame of image data with a second resolution, and

wherein the first resolution is greater than the second resolution.

9. The video device of claim 7,

wherein said recording, via a first video camera, a first image of a first field of view at a first time comprises recording via the first video camera as arranged such that the first field of view is in a first direction,

wherein said recording, via a second video camera, a third image of a second field of view at a third time comprises recording via the second video camera as arranged such that the second field of view is in a second direction, and

wherein the first direction is opposite to the second direction.

10. The video device of claim 7,

wherein said recording, via a second video camera, a third image of a second field of view at a third time comprises recording, via the second video camera, such that the first time is different than the third time, and

wherein said recording, via the second video camera, a fourth image of the second field of view at fourth time comprises recording, via the second video camera, such that the second time is different than the fourth time.

11. The video device of claim 10,

wherein said recording, via the second video camera, such that the first time is different than the third time comprises recording, via the second video camera, such that the first time is after the third time, and
