Abstract
Apparatus for automatic replacement of a billboard in a video image is provided. The billboard comprises a chroma-key surface, and the apparatus includes a video camera for viewing the billboard, and a chroma-key unit operative to detect at least one chroma-key color of the billboard chroma-key surface. A reference color of the chroma-key unit is adjustable to conform to the color of the chrom-key surface, thereby enabling the chroma-key unit to correctly identify the billboard surface and to correctly replace the chroma-key surface of the billboard by a virtual advertisement in a video image with correct occlusion of any foreground object.
