Abstract
An image apparatus and method of the same use a circular marker having two semicircular portions of first and second color areas separated by a center line. An image of a real space including the marker is acquired and an area of the marker is detected from the image. Center coordinates of the marker, for arranging a virtual object in the real space, are calculated based on coordinates of tangents with the area of the marker in a horizontal direction and a vertical direction of the image. Angles of the marker, for arranging the virtual object in the real space, are calculated based on the area of the marker. Then, an image, which has the virtual object arranged in the real space by the position and angles indicated by the marker, is constructed based on the calculation results and shape data of the virtual object.
