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.

To increase the space efficiency of an imaging apparatus which deals with a speckle pattern. An imaging apparatus includes a first image sensor and a second image sensor. The first image sensor images light entering the first image sensor from an object through an optical system to generate image data of the object. The second image sensor images a speckle pattern formed by scattering of light striking the object to generate image data of the speckle pattern, the speckle pattern entering the second image sensor through the optical system. In the imaging apparatus, the first image sensor and the second image sensor are placed side by side in an optical axis direction of the optical system.

Time of Flight (ToF) depth image processing methods. Depth edge preserving filters are disclosed with superior performance to standard edge preserving filters applied to depth maps. In particular, depth variance is estimated and used to filter while preserving depth edges. In doing so, filter strength is calculated which can be used as an edge detector. A confidence map is generated with low confidence at pixels straddling a depth edge, and which reflects the reliability of the depth measurement at each pixel.
