Kind Code:
A1
Abstract:
A method for synthesizing a chroma key image by a chroma key synthesizer, according to one embodiment of the present invention, comprises the steps of: photographing a first image in which an object is not included in a background, and reading and maintaining color information of the first image; capturing a second image in which the object is included in the background, and reading and maintaining color information of the second image; obtaining an object image resulting from removing the background and extracting only the object form the second image, by eliminating, from the second image, a color value corresponding to the color information of the first image; capturing an infrared image in which the object is included in the background and obtaining, from the infrared image, an object depth image in which the object is tracked, through depth information read from the infrared image; correcting the object image through the object depth image; and synthesizing the object image which has been corrected with a selected background image.
