1. A video navigation apparatus comprising: a photographing unit that photographs a scene; an estimating unit that estimates a position and angles of the photographing unit; an estimate image generating unit that generates an estimate image corresponding to estimate values of a position and angles of the photographing unit estimated by the estimating unit; a collating unit that collates an estimate image generated by the estimate image generating unit with a scenery image photographed by the photographing unit, and corrects an estimate value estimated by the estimating unit according to a result of the collation; an indication image generating unit that generates an indication image by processing indication information indicated in advance based on position information that shows a position of the photographing unit and angle information that shows angles of the photographing unit after correction processing by the collating unit; and a display unit that displays an indication image generated by the indication image generating unit.
