1. An information processing apparatus comprising:
an image obtaining section configured to obtain data of polarized light images in a plurality of directions, the polarized light images being photographed by an imaging device provided to a moving body;
a polarization degree obtaining section configured to obtain distribution of degrees of polarization by using the polarized light images;
a high polarization degree region evaluating section configured to detect a peripheral edge of a play field on which the moving body is present, by evaluating a shape of a high polarization degree region having degrees of polarization higher than a threshold value in a state in which the high polarization degree region is overlooked from directly above the moving body, where the high polarization degree region evaluating section detects the peripheral edge of the play field by identifying a missing part in an arc shape representing the high polarization degree region and corresponding to an angle of view; and
an output data generating section configured to generate and output output data for avoiding movement to the peripheral edge.
