Abstract: A detection area 112 is set in a three-dimensional space in which a subject exists. When an actual hand enters the detection area 112, coordinate points (white and black dots) represented by pixels making up a silhouette 114 of the hand in a depth image enter the detection area 112. In the detection area 112, a reference vector 126 is set that shows the direction which the hand should face relative to the shoulder as a reference point 122. Then, an inner product between two vectors, a vector from the reference point 122 to each of coordinate points and the reference vector 126, is calculated, followed by comparison between the inner products. Positions of coordinate points whose inner products are ranked high are acquired as the position of tips of the hand.

Abstract: A position detection system includes an event-driven vision sensor that includes a sensor array including sensors each generating an event signal when a change in the intensity of incident light is detected, a microlens array that includes at least first and second microlenses for guiding the light to first and second regions of the sensor array, respectively, and a terminal device that has a reception unit for receiving the event signal from the vision sensor and a position detection unit for detecting the three-dimensional position of the change in the intensity of light, from the event signal generated by each sensor in the first region and the second region.

Abstract: An image generation apparatus 200 includes a distortion information storage section 234 that stores, as distortion information, information for deforming and distorting an image, and a distortion rendering section 232 that renders a distorted image by rasterization processing using the distortion information without generating a non-distorted image in a memory. The distortion rendering section 232 renders the distorted image by executing the rasterization processing on a distorted triangle obtained by transforming a triangle to be rasterized on the basis of the distortion information such that the processing is executed upward and downward from positions of vertices of the distorted triangle.

Abstract: An operation object includes a polyhedron. The polyhedron includes characteristic surfaces formed by cutting each vertex of a cube at different angles. An information processing apparatus acquires a normal vector of each surface from a polarized image thereof. Further, the information processing apparatus identifies the characteristic surface by defining, as a characteristic amount, an angle formed by an average vector Na of normal vectors N1, N2, and N3 of reference surfaces that orthogonally intersect each other and a normal vector N0 of the characteristic surface surrounded by the reference surfaces. The specification result and the normal vectors thereof are used to acquire the position and orientation of the operation object.

Abstract: A first estimating unit estimates at least one of a position and an attitude of a predetermined object on the basis of an image of a periphery of the object, the image being obtained from an imaging device, and generates an estimation result not including an accumulated error. A second estimating unit estimates at least one of the position and the attitude of the object on the basis of the image, and generates an estimation result including an accumulated error. A correcting unit compares the estimation result of the first estimating unit and the estimation result of the second estimating unit with each other, and corrects, on the basis of a result of the comparison, a subsequent estimation result of the second estimating unit, the subsequent estimation result being subsequent to the estimation result of the second estimating unit which estimation result is used for the comparison. An App executing unit performs predetermined data processing on the basis of the estimation result of the second estimating unit which estimation result is corrected by the correcting unit.

Abstract: Methods and apparatus provide for: capturing an image of an object, which includes a face of a person wearing an optical display apparatus by which to observe a stereoscopic image that contains a first parallax image and a second parallax image obtained when the object in a three-dimensional (3D) space is viewed from different viewpoints; identifying the optical display apparatus included in the image of the object; and generating an image of the face of the person that does not include the optical display apparatus by excluding the identified optical display apparatus, and instead by adding features of the face of the person to a region in which the identified optical display apparatus is excluded.
