Modulation of background substitution based on camera attitude and motion
First Claim
Patent Images
1. A mobile device comprising:
- an imager configured to provide a first depth image including a first foreground and a first original background and a subsequent second depth image including a second foreground and a second original background;
a storage configured to store a substitute background;
a sensor configured to sense movement of the mobile device; and
a processor configured to;
separate the first foreground from the first original background of the first depth image,replace the first original background with the substitute background to form a first composite imagemodulate the substitute background as a function of a movement of the mobile device sensed by the sensor to form a modulated substitute background, andreplace the second original background with the modulated substitute background to form a second composite image.

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 composite images from a mobile device, the method comprising:
-
obtaining a first depth image using an imager in the mobile device, the depth image including a first foreground and a first original background; detecting movement of the mobile device using a sensor in the mobile device; obtaining a second depth image using the imager in the mobile device, the second depth image including a second foreground and a second original background; separating the first foreground from the first original background of the first depth image; replacing the first original background with a pre-stored substitute background to form a first composite image; modulating the substitute background as a function of the movement of the mobile device detected by the sensor to form a modulated substitute background; replacing the second original background with the modulated substitute background to form a second composite image. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
