<p>PROBLEM TO BE SOLVED: To determine more accurately the azimuth of a timing of photography.SOLUTION: Azimuth information is determined by utilizing earth magnetism, and attitude information of an information processing unit is acquired without utilizing the earth magnetism, and it is determined whether or not a variation of the azimuth to which the information processing unit is faced, which is shown by the azimuth information agrees with a variation of the direction to which the information processing unit is faced, which is determined from the attitude information, to thereby determine validity of the azimuth information determined by utilizing the earth magnetism.</p> |
