First Claim
Patent Images
1. A mobile device comprising:
- an imager configured to provide a depth image including a foreground and an original background;
a sensor configured to sense movement of the mobile device; and
a processor configured to separate the foreground from the original background, to replace the original background with a substitute background to form a substitute image, and to change the substitute background based on the sensed movement of the mobile device.

Abstract
A device and method of background substitution are disclosed. One or more cameras in a mobile device obtain a depth image. A processor in or external to the device segments the foreground from the background of the image. The original background is removed and a stored background image or video is substituted in place of the original background. The substituted background is altered dependent on the attitude and motion of the device, which is sensed by one or more sensors in the device. A portion of the stored background selected as the substitute background varies in correspondence with the device movement.

13. A method of providing an image from a mobile device, the method comprising:
-
obtaining a depth image using an imager in the mobile device, the depth image including a foreground and an original background; detecting movement of the mobile device using a sensor in the mobile device; separating the foreground from the original background; replacing the original background with a stored substitute background to form a substitute image; and changing the substitute background with respect to the foreground to correspond with the detected movement of the mobile device. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
