A speckle pattern is effectively utilized. An information processing apparatus is an information processing apparatus including a light output unit and an acquisition unit. The light output unit included in the information processing apparatus is for outputting a plurality of light beams for generating a speckle pattern, to a plurality of locations of objects which are within an imaging range. Also, the acquisition unit included in the information processing apparatus is for acquiring the speckle patterns formed by scattering of the plurality of light beams striking the plurality of locations on a location-by-location basis.

An imaging apparatus includes: an imaging unit that generates image data; a feature information generation unit that generates feature information smaller in data amount than the image data, the feature information indicating features of a subject image included in an image corresponding to the image data; an imaging-side first and second communication units; a communication status determination unit that determines the status of communication between an external communication device and the imaging-side first communication unit; and an imaging-side communication control unit that transmits the feature information to the communication device via the imaging-side second communication unit when the status of communication between the communication device and the imaging-side first communication unit is not favorable.
