MARKER GENERATION APPARATUS, MARKER RECOGNITION APPARATUS, MARKER GENERATION METHOD, MARKER RECOGNITION METHOD, AND PROGRAM

A marker generation apparatus includes code acquisition means for acquiring N-bit code information (N is a natural number no less than two) for superimposing the code information on a marker defined in a plurality of areas, multiplication means for multiplying each bit value of the code information acquired by the code acquisition means by an M-sequence matrix respectively, color information calculation means for calculating color information by adding up multiplication results obtained by the multiplication means, the color information being used for performing a color arrangement for each area of the marker, and color arrangement means for performing a color arrangement for each area of the marker based on the color information calculated by the color information calculation means.
