Imaging apparatus, information processing apparatus and method, and computer program therefor
First Claim
1. An imaging apparatus that captures an image, comprising:
- an imaging unit configured to capture an image;
a recording unit configured to perform a process of recording the captured image on a recording medium;
a first position estimating unit configured to estimate a position of the imaging 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 imaging 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.
