Abstract
An electronic imaging system useful for compositing images includes an electronic camera for capturing multiple images, including a first image of a subject plus background and a second image of the background only. The first and second images are subtracted to generate a difference image, and the difference image is processed to generate a mask image. The mask image is then applied to the first image to select an area in which the subject is located, whereby the selected subject area is used in the compositing of a new image.
