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.’

Abstract: An image obtaining section of an information processing apparatus obtains polarized light images in a plurality of directions from an imaging device provided to a moving body. A polarization degree obtaining section of an image analyzing section obtains a degree of polarization on the basis of direction dependence of luminance of polarized light. A high polarization degree region evaluating section detects the peripheral edge of a play field on which the moving body is present, by evaluating the 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. An output data generating section generates and outputs output data for avoiding movement to the peripheral edge.

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: In an information processing device, a photographed image acquiring unit acquires an image which has been photographed by a camera attached to a head mount display. A region determining unit predicts a region which a user gazes at in a display image. An image analyzing unit has a first fineness processing unit and a second fineness processing unit, with the former analyzing a region corresponding to the gaze region in the photographed image with a higher fineness than the latter. An information processing unit performs information processing by using the result of analysis. An image generating unit has a first fineness processing unit and a second fineness processing unit, with the former generating a display image on the gaze region with a higher fineness than the latter. An output unit sends data of the display image to the head mount display.

Abstract: A captured image acquisition section of an information processing apparatus acquires polarization image data including polarization information in a plurality of azimuths. An imaging apparatus information acquisition section acquires information regarding a position and posture of an imaging apparatus. A viewpoint control section of a subject information acquisition section controls a plurality of viewpoints from which polarization images are captured. A point-of-interest information acquisition section sets a pixel of interest having a degree of polarization equal to or higher than a threshold in a polarization image of a first viewpoint, identifies a pixel representing the same point of interest in a polarization image of a second viewpoint, and then obtains a line of intersection between incident planes acquired for the respective viewpoints as a normal vector. An output data generation section generates output data based on results thereof and outputs the data.

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 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.
