Abstract:
A hard disk drive stores hierarchical image data, a speed map holding, for each tile image, an index of the processing time required to render a tile image having a predetermined image size obtained by partitioning the image, and scenario data which defines viewpoint shifting. In a control unit of an information processing apparatus having a function of displaying an image, an input information acquisition unit acquires information with respect to the user's input operation via an input device. A loading unit loads necessary data for image displaying from the hard disk drive. A shifting condition adjustment unit adjusts the viewpoint shifting speed based upon the speed map. A frame coordinate determination unit sequentially determines frame coordinates of a display area. A decoding unit decodes compressed image data. A display image processing unit renders a display image.
Abstract:
An information processor acquires a stereo image from an imaging device. A detection plane definition portion defines a detection plane in a three-dimensional space of a camera coordinate system of a first camera. A feature quantity calculation portion generates feature point image of left and right images. A parallax correction area derivation portion derives an area as a parallax correction area, which is obtained by moving, to a left, an area of the right image identical to the detection area of the left image. A matching portion performs matching for the feature point images of each area, thus deriving a highly rated feature point. A position information output portion generates information to be used by an output information generation section based on the matching result.
Abstract:
An information processing device that detects the position of a subject shot by a camera in a three-dimensional space is provided. The information processing device includes a depth image acquiring section that acquires a depth image in which the distance of a subject in the depth direction from the camera is represented as a pixel value on an image plane, a spatial structure identifying section that identifies the position of a plane forming a predetermined angle with a gravity vector among subject surfaces by detecting a coordinate point collection representing the plane on the basis of the distribution of coordinate points obtained by inverse projection of pixels of the depth image to the three-dimensional space based on the direction of the gravity vector, and a target object extracting section that generates and outputs position information of a predetermined target object on the basis of the position of the plane.
Abstract:
An information processor includes: a similarity data generation portion generating similarity data that represents the calculated similarity to the image in the reference block in association with a position within the search range; a result evaluation portion detecting a position with a maximum similarity value for each piece of the similarity data and screening the detection result by making a given evaluation of the similarity; a depth image generation portion finding a parallax for each of the reference blocks using the detection result validated as a result of screening, calculating a position of a subject in a depth direction on a basis of the parallax, and generating a depth image by associating the position of the subject in the depth direction with an image plane; and an output information generation section performing given information processing on a basis of the subject position in a three-dimensional space using the depth image and outputting the result of information processing.
Abstract:
A game controller includes a plurality of LEDs formed on the rear of a case. The plurality of LEDs are arranged two-dimensionally in its layout area. The game controller has a plurality of PWM control units which are provided inside the case and control the lighting of the plurality of LEDs, respectively. The PWM control units control the lighting of the LEDs based on a control signal from a game apparatus. The game apparatus acquires a captured image of the game controller, and acquires the position of the game controller in the captured image based on the positions of the LEDs in the captured image.
Abstract:
An input information obtaining portion of a control section obtains requests input from an input device by a user, which requests include a display region moving request to enlarge/reduce or scroll an image displayed on a display device and a request to generate/erase a viewport, change the size of a viewport, or move a viewport. A viewport control portion successively determines the number, arrangement, and size of viewports accordingly. A display region determining portion determines the region of an image to be displayed next in each viewport. A loading portion determines tile images to be newly loaded, and loads the data of the tile images from a hard disk drive. A decoding portion decodes the data of tile images used for rendering the image in each viewport. A display image processing portion updates the display region independently for each viewport.
Abstract:
An image pickup apparatus includes: an image data production unit configured to produce data of a plurality of kinds of images from a picked up image and successively output the data; an image synthesis unit configured to cyclically connect the data of the plurality of kinds of images for each pixel string within a range set in advance for each of the kinds of the images and output the connected data as a stream to produce a virtual synthetic image; and an image sending unit configured to accept, from a host terminal, a data transmission request that designates a rectangular region in the virtual synthetic image, extract and connect data from the stream and transmit the connected data as a new stream to the host terminal.

Abstract:
An original image to be edited is displayed using hierarchical data. As a user draws a figure in a region of the image as an edit action, an image data updating unit generates a layer having a hierarchical structure composed of the rendered region only. More specifically, the image of the region to be edited is used as the lowermost hierarchical level, and upper hierarchical levels than this lowermost level are generated by reducing the lowermost level, as appropriate, so as to produce hierarchical data. As, during image display, it is checked that the updated region is contained in a frame to be displayed anew, the image of the layer is displayed by superposing the frame on the original hierarchical data.
