Imaging apparatus, information processing apparatus and method, and computer program therefor

An information processing apparatus comprising:

• a first position estimating unit configured to estimate a position of the information processing apparatus using a first position estimation technique to generate first position information, and to calculate a first evaluation value serving as accuracy evaluation information of the first position information;
• a second position estimating unit configured to estimate the position of the information processing apparatus using a second position estimation technique to generate second position information, the second position estimation technique being different from the first position estimation technique, and to calculate a second evaluation value serving as accuracy evaluation information of the second position information;
• a position-information obtaining unit configured to select, from the first position information and the second position information, position information whose evaluation value is higher than the other;
• and
• an application executing unit configured to perform data processing using the position information selected by the position-information obtaining unit.

An information processing method performed by an information processing apparatus, comprising the steps of:

• with a first position estimating unit, estimating a position of the information processing apparatus using a first position estimation technique to generate first position information, and calculating a first evaluation value serving as accuracy evaluation information of the first position information;
• with a second position estimating unit, estimating the position of the information processing apparatus using a second position estimation technique to generate second position information, the second position estimation technique being different from the first position estimation technique, and calculating a second evaluation value serving as accuracy evaluation information of the second position information;
• with a position-information obtaining unit, selecting, from the first position information and the second position information, position information whose evaluation value is higher than the other;
• and
• with an application executing unit, performing data processing using the selected position information.

A computer program for causing an information processing apparatus to perform information processing, the information processing comprising the steps of:

• causing a first position estimating unit to estimate a position of the information processing apparatus using a first position estimation technique to generate first position information, and to calculate a first evaluation value serving as accuracy evaluation information of the first position information;
• causing a second position estimating unit to estimate the position of the information processing apparatus using a second position estimation technique to generate second position information, the second position estimation technique being different from the first position estimation technique, and to calculate a second evaluation value serving as accuracy evaluation information of the second position information;
• causing a position-information obtaining unit to select, from the first position information and the second position information, position information whose evaluation value is higher than the other;
• and
• causing an application executing unit to perform data processing using the selected position information.
