Abstract: In an information processing apparatus, a captured image acquiring section acquires data of an image captured of a reference object while part of incident light applied thereto is being blocked. An incident light information acquiring section acquires, according to a predetermined model equation, a brightness distribution of partial incident light in each of light-blocked states on the basis of the image of the reference object, and acquires a brightness distribution of overall incident light by calculating brightness distributions of partial incident light. A target information acquiring section acquires the shape and material of a target by using the brightness distribution of overall incident light.

Abstract: An input information acquiring section accepts a user's operation. A texture region acquiring section acquires a region of a display image to be presented by use of a texture. A velocity acquiring section acquires for each pixel a movement velocity vector of the texture on a plane of the display image. A texture referencing section adjusts a reference range in an axial direction of the velocity vector in keeping with a magnitude of the movement velocity, before sampling texel values. A pixel value determining section determines a pixel value on the basis of the texel values. An output section outputs the display image.

Abstract: Provided is a head-mounted device that includes a housing, first imaging means, and second imaging means. The housing is to be mounted on the head of a user. The first and second imaging means are mounted on the housing to capture images from different angles of view. The head-mounted device receives an image captured by the first imaging means, detects an image portion corresponding to a body portion of the user from the received image, and estimates, based on information indicative of the detected image portion, a possible existence range of a predetermined part of the body of the user within an image captured by the second imaging means.

Abstract: A display control apparatus includes a display control section that generates a virtual space image by specifying a viewpoint position and a direction of line of sight and displays the image on a head-mounted display. The display control section can specify a plurality of positions in the virtual space as viewpoint positions and can change the viewpoint position to a position determined from among the plurality of positions in accordance with an attitude of the head-mounted display, and when the viewpoint position is changed, the display control section specifies, as a direction of line of sight, the direction in which a first position in the virtual space is seen from the changed viewpoint position.

Abstract: A gaming apparatus includes a position control section and a display control section. The position control section controls a position of an object arranged in a virtual 3D space based on a relative position between an input apparatus used by a user wearing a head-mounted display and the head-mounted display. The display control section generates an image in the virtual 3D space including the object and displays the image on the head-mounted display. When a distance between the input apparatus and the head-mounted display is equal to a first distance or more, the position control section linearly changes the object position in response to a change in position of the input apparatus. When the distance between the input apparatus and the head-mounted display is less than the first distance, the position control section determines the object position in accordance with a criterion different from that used when the distance between the input apparatus and the head-mounted display is equal to the first distance or more.

Abstract: An image acquisition section of an information processing apparatus acquires, from an imaging apparatus, polarization images in a plurality of orientations. A normal acquisition section of an image analysis section detects a surface of a subject by acquiring a normal vector on the basis of orientation dependence of polarization luminance. A surface assumption section assumes the presence of an undetected surface continuing from the detected surface. A subject detection section confirms whether or not the assumed surface is present using a normal vector estimated for the assumed surface. An output data generation section generates and outputs output data using information regarding the detected surface.

Abstract: A point-of-interest information acquisition section of an information processing apparatus acquires, by using a polarization image captured from a viewpoint of an imaging apparatus, an incident plane relative to the viewpoint at a point of interest ‘a’ on a subject. A viewpoint control section determines a direction of movement of the imaging apparatus in such a manner as to suitably acquire an angle formed with the incident plane and presents the direction to a user. When the post-movement viewpoint of an imaging apparatus is determined to be appropriate, an incident plane at the point of interest ‘a’ is acquired by using the captured polarization image, and a line of intersection with the incident plane is assumed to be a normal vector n of the point of interest ‘a.’
