An object region detection unit () decides the region of a physical object of interest in a physical space image. An image manipulation unit () performs shading processing of an inclusion region including the decided region. A rendering unit () arranges a virtual object in virtual space at the position and orientation of the physical object of interest and generates a virtual space image based on the position and orientation of the user's viewpoint. A composition unit () generates a composite image by superimposing the virtual space image on the physical space image that has undergone the shading processing and outputs the generated composite image to an HMD ().

Image processing apparatus and image processing method

An index detecting section detects an index in a physical space, from a captured image obtained by an imaging apparatus. An erroneous-detection prevention processing section performs erroneous-detection prevention processing, based on information relating to image coordinates of a detected index. An image output section outputs, to a display device, an image having been subjected to the erroneous-detection prevention processing. This prevents an image displayed on the display device from being mistaken for a real index when the display device is in the field of view of the imaging apparatus.

Information processing apparatus and method

An information processing apparatus includes a region segmentation unit configured to segment each of a plurality of images shot by an imaging apparatus for shooting an object from a plurality of viewpoints, into a plurality of regions based on colors of the object, an attribute determination unit configured to determine, based on regions in proximity to intersections between scanning lines set on the each image and boundary lines of the regions segmented by the region segmentation unit in the each image, attributes of the intersections, a correspondence processing unit configured to obtain corresponding points between the images based on the determined intersections' attributes, and a three-dimensional position calculation unit configured to calculate a three-dimensional position of the object based on the obtained corresponding points.

Information processing apparatus, three-dimensional position calculation method, and program

An information apparatus is provided. The information processing apparatus includes a viewpoint position measurement unit configured to measure a position of a viewpoint of an operator, an operation position measurement unit configured to measure a position of an operation unit operated by the operator, and a determination unit configured to determine a position and an orientation of a cursor to be displayed based on the position of the viewpoint and the position of the operation unit.

Information processing apparatus for displaying virtual object and method thereof

Image display method of superimposing virtual space image data on real space image data at an arbitrary viewpoint and exhibiting the superimposed image to a viewer is provided. When real space image data, including a prototype generated based on three-dimensional CAD data, is captured by an image sensing device, the position and orientation of the image sensing device and the prototype are tracked, and position/orientation data indicative of the position and orientation of the prototype in the image is acquired. Based on the position/orientation data and the three-dimensional CAD data, a three-dimensional computer graphic image is rendered so as to overlap the prototype in the image, thereby synthesizing the image with the three-dimensional computer graphic image. The synthesized image is then displayed.

Image display apparatus and method

A dictionary management apparatus is disclosed, which can optimize a dictionary required for speech synthesis of character data. The apparatus checks if character data which is to undergo speech conversion includes character data which is not registered in the dictionary. When the unregistered character data is included, the apparatus generates new dictionary data of that character data using another dictionary and adds the generated new dictionary data to the dictionary.

Dictionary management apparatus for speech conversion

This invention has as its object to provide a high-quality composite image of a real image and virtual image to a viewer or the like. To achieve this object, the position/posture of photographing means for photographing a performer or the like is measured, the position/posture of an HMD, which the performer or the like wears, and which allows the viewer to see through the external world, is measured, a CG at the viewpoint of the photographing means and image data photographed by the photographing means are aligned and composited on the basis of the measurement result of the position/posture of the photographing means, CG at the viewpoint of the HMD and image data photographed by a camera built in the HMD are aligned and composited on the basis of the measurement result of the position/posture of the HMD, and image data is displayed on the HMD.

Image processing apparatus and method with setting of prohibited region and generation of computer graphics data based on prohibited region and first or second position/orientation

In a character provision service system for providing users with characters such as interface agents and virtual characters in virtual spaces on computers or in TV games, charges for use of a provided character is computed according to a motion made by the character. This system enables each user to easily purchase with security a character capable of moving according user's need, and also enables character data providers to collect charges according to motions made by provided characters and to provide various characters without anxiety about unauthorized use of the characters.

Character provision service system, information processing apparatus, controlling method therefor, and recording medium

A speech synthesis apparatus for outputting synthesized speech on the basis of a parameter sequence of a speech waveform includes a parameter generation unit which generates a parameter sequence for speech synthesis on the basis of a character sequence input by a character sequence input unit, and stores the generated parameter sequence in a parameter storage unit. A waveform generation unit is also provided that generates pitch waveforms each for one pitch period on the basis of synthesis parameters and pitch scales included in the parameter sequence, and generates a speech waveform by connecting the generated pitch waveforms in accordance with frame lengths set by a frame length setting unit.

Speech synthesis apparatus and method

A speech information processing apparatus includes a statistical processing unit for extracting features by performing statistical processing of a feature file formed by extracting features of speech, such as the fundamental frequency and its variations, and the power and its variations of speech, from a speech file, and a label file in which a phoneme environment, comprising the accent type, the number of moras, the mora position, phonemes and the like, is considered, and a pitch pattern forming unit for forming a pitch pattern, in which phoneme environment is considered, based on the result of the statistical processing.

Method and apparatus for processing speech information using a phoneme

A document inputting apparatus or speech outputting apparatus inputs and displays document data, specifies accent information, pronunciation information and syllable-length information of words or characters of the document data. The apparatus displays the document data in accordance with the specified information so that information such as the accent positions or accent intensities can be recognized. Thus formed document data is stored in a memory with the accent information, the pronunciation information or the syllable-length information. Upon reading the document data from the memory and outputting it as speech, the specified information is referred to for speech synthesizing, thus outputting speech corresponding to the correct pronunciation.

Document inputting method and apparatus and speech outputting apparatus

A data processing apparatus for synchronized audiovisual output has synchronizing signal bits which are assigned to bits of each sound data, represented by a 16-bit PCM code. A predetermined bit of the assigned bits having the least influence upon the human auditory sense is extracted as a synchronizing signal bit for synchronization of the image data output and sound output.
