APPARATUS AND METHOD FOR IMAGE COMPOSITING
First Claim
Patent Images
1. An image compositing apparatus provided with a fare adjustment function, which takes a picture of a subject, composites a foreground (subject) image of the picture with a background image, and prints out the composite image with a printer, the apparatus comprising:
- light panels provided behind the subject and on the floor, which uniformly emit uniform light with predetermined hue, saturation and brightness;
a means for measuring the hue, saturation and the brightness of the light panels provided behind the subject and on the floor;
a memory for memorizing the hue, saturation and the brightness of the light panels provided behind the subject and on the floor;
an image extracting means for extracting the foreground image of the picture based on a color of a light panel behind the subject;
an image compositing means for comparing and correcting saturation, brightness and hue distributions of the foreground image with respect to saturation, brightness and hue distributions of the background image, and compositing the foreground image with the background image; and
an image display for displaying the resultant composite image.

Abstract
The present invention provides an image compositing apparatus capable of producing a natural composite image, with a simple structure and a less occupying space. The present invention also provides a method for compositing an image by providing shadow-free conditions in a limited space for chroma-keying so that a subject image and a desired background image are naturally integrated as one image.

2. An image compositing method for taking a picture of a subject, compositing a foreground (subject) image of the picture with a background image by chroma-keying, and printing out the composite image with a printer, the method comprising the steps of:
-
extracting the foreground image;
memorizing saturation, brightness and hue distributions of the background image; and
correcting saturation, brightness and hue distributions of the foreground image with respect to the saturation, brightness and hue distributions of the background image.
