Abstract: In a storage device are stored, as reference maps, a background map, a color map of an object, and a height map of the object as hierarchical data having a plurality of resolutions. An image processing device loads, when necessary, portions thereof which are required for rendering into a main memory 26-according to movement of a viewpoint, etc., decodes and decompresses portions thereof, and develops the resulting pieces of data in a memory inside a GPU. The GPU refers to these pieces of data to render a display image through ray tracing.

Abstract: A feeling deduction unit 100 deduces a user's feeling. An internal state management unit 110 manages an internal state of an object and an internal state of a user on the basis of the deduced user's feeling. An action management unit 120 determines an action of the object on the basis of the internal state of the object. An output processing unit 140 causes the object to perform the action determined by the action management unit 120.

Abstract: A distorted image generating section directly renders an image having a distortion such that a proper image can be seen when viewed through an eyepiece lens. Specifically, the distorted image generating section calculates which position a target pixel on a view screen will be displaced to by the lens, generates a ray of light that passes from a viewpoint through a pixel at a displacement destination, and uses color information obtained by ray tracing as a pixel value of the target pixel.

Abstract: A captured image acquisition section 50 acquires, from an imaging apparatus 12, data of a polarized image obtained by capturing a target object and stores the data into an image data storage section 52. A normal line distribution acquisition section 362 of a region segmentation section 310 acquires a distribution of normal line vectors of a subject surface using the polarized image. A region decision section 312 evaluates the distribution of normal line vectors with a predetermined criterion indicating stability such as a dispersion and determines a region in which the stability is high as a region of a figure of a subject to segment the image. An output data generation section 56 carries out various processes using a result of the segmentation to generate output data.

Abstract: Content data of a display target is acquired in accordance with a user's operations and is used to determine a configuration of a display image. Of the regions to be rendered using fonts in the display image, the region in which a character is to be displaced by a very small amount is determined. The characters targeted for displacement are rendered while being displaced over time in accordance with predetermined displacement rules. The characters not targeted for displacement are rendered in a reference position. With all characters rendered, the display image is completed and output. The processes of S12 to S24 are repeated until display is terminated.

Abstract: In a calibration apparatus, a captured image acquisition unit acquires data of an image of a calibration chart captured by a fish-eye imaging apparatus. A distortion correction unit makes an assumption of a parameter of the imaging apparatus, takes into account a projection system to make a correction, and adjusts the parameter until an image of the original chart is obtained. A pseudo image drawing unit uses model data of a chart to draw a pseudo captured image. A point-of-view adjustment unit compares the pseudo image and the captured image and adjusts a point-of-view position of a virtual camera according to a difference between positions of markers or intervals of patterns to specify a position of the imaging apparatus.

Abstract: An image of a block or the like entering a space above a play mat is picked up by an image pickup apparatus, and an information processing apparatus detects and recognizes the block on the basis of a picture of the block in a picked up image and performs information processing. The play mat includes a play field that defines a detection space for the block, and a calibration chart including at least a plurality of regions of colors of different luminances. The image pickup apparatus adjusts an exposure time period, a gain value for each color component and a correction rule upon gamma correction on the basis of the picture of the calibration chart in the picked up image.

Abstract: An image data generating block 72 of an image capturing apparatus 12 generates polarized images having two or more resolutions from luminance of polarization in two or more directions acquired by a luminance data acquiring block 70. A pixel value converting block 74 generates new image data with a predetermined parameter being a pixel value on the basis of the polarized luminance in two or more directions. A transmission image generating block 76 connects image data of two or more types on a predetermined pixel line basis and then crops the requested data, thereby stream-transferring the cropped data from a communication block 78. A target object recognizing block 80 of an information processing apparatus 10 recognizes the state of a target object by use of the transmitted data and an output data generating block 82 generates output data by use of the recognized state. A communication block 86 requests the image capturing apparatus 12 for the data including type, resolution, and region corresponding to the state of the target object.

Abstract: A detection area is set in a three-dimensional space in which a subject exists. When an actual hand enters the detection area, coordinate points (white and black dots) represented by pixels making up a silhouette of the hand in a depth image enter the detection area. In the detection area, a reference vector is set that shows the direction which the hand should face relative to the shoulder as a reference point. Then, an inner product between two vectors, a vector from the reference point to each of coordinate points and the reference vector, 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: [Object] To perform more stable and highly accurate attitude estimation.[Solution] The attitude optimization unit optimizes the articulation position, the angle, the number of articulations, and the like which are attitude parameters of a human body model (tree structure) by a plurality of optimization techniques so as to match a region in which a human body can exist, and switches among a plurality of optimization techniques and uses an optimum technique. Note that optimization techniques include 1. initial value, 2. algorithm, and 3, restriction, and optimization is performed by switching among these three. For example, it is possible to apply the present disclosure to an image processing device that performs image processing of optimizing the articulation position and angle of a human body model.
