Portable electronic devices with integrated image/video compositing
First Claim
1. A portable electronic device, comprising:
- a user control;
a camera operative to acquire a digital image in response to the user control, the digital image including foreground subject matter and a background scene;
a memory for storing the digital image; and
a processor within the portable electronic device, the processor being operative to perform the following functions;
a) receive the digital image acquired by the camera, andb) perform an operation on the digital image to differentiate the foreground subject matter from the background scene, thereby enabling the foreground subject matter to be resized or repositioned separately from the background scene.

Abstract
Digital imagery is composed or composited within a smartphone or other portable electronic device to merge foreground and background subject matter acquired simultaneously with different cameras or acquired at different times with the same camera. A processor stores the digital imagery along with information derived or used by an operation to differentiate the foreground subject matter from the background scene, which may be a digital matting operation, and/or may involve finding an edge or an outline of the foreground subject matter. The foreground subject matter and the background scene may be stored as different graphical layers in the memory. A user control such as a touchscreen may enable a user to select and resize or reposition the foreground subject matter on a background scene of a separately acquired image. The digital imagery may constitute a still image or a sequence of images representative of motion video.

17. A method of composing a digital image, comprising the steps of:
-
providing a portable electronic device including one or more digital cameras, a memory, a display and a processor; acquiring background imagery with one of the cameras of the portable electronic device; acquiring foreground imagery with one of the cameras of the portable electronic device; performing a matting operation on the foreground imagery to extract foreground subject matter from the foreground imagery; automatically generating composite imagery by inserting the foreground subject matter into the background imagery using the processor within the portable electronic device; and displaying the composite imagery on the display of the portable electronic device. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
