摘要： When a CG object is overlapped onto a photographed real scenery image as a background and an image of a photographed real photographic subject is synthesized in front of the overlapped image, an image in which the photographed real background and the photographic subject are imaged simultaneously without imaging the photographed real background and the photographic subject independently, is synthesized with CG. A photographed real image including a specific image is acquired, and area information representing an area of the specific image from the photographed real image, and an area other than the area of the specific image of the photographed real image is synthesized with a computer graphics image using the area information so detected.

摘要： In an information processing method for maintaining, in a system in which each of a plurality of processes connected via a network holds and uses shared data to be shared by the processes, consistency of shared data held by the respective processes, when a manipulation request for the shared data is generated, an event indicating that manipulation request is output onto the network. An event as a reply to the event output onto the network is received from the network. A manipulation for the shared data is executed in accordance with the received event. In this way, the manipulation execution timings for shared data to be shared by a plurality of processes can be accurately matched.

摘要： A view transformation matrix that represents the position/attitude of an HMD is generated based on a signal that represents the position/attitude of the HMD (S602). On the other hand, landmarks and their locations are detected based on a captured picture (S604) and a calibration matrix ΔMc is generated using the detected locations of the landmarks (S605). The position/attitude of the HMD is calibrated using the view transformation matrix and calibration matrix ΔMc generated by the above processes (S606), a picture of a virtual object is generated based on external parameters that represent the position/attitude of the calibrated HMD, and a mixed reality picture is generated (S607). The generated mixed reality picture is displayed in the display section (S609).

摘要： There is disclosed a mixed reality presentation apparatus which generates and displays a three-dimensional virtual image on a see-through display device so as to allow a plurality of players to play a multi-player game in a mixed reality environment. The apparatus has a CCD camera for detecting the mallet positions of the plurality of players, and a sensor for detecting the view point position of each player in the environment of the multi-player game. The apparatus generates a three-dimensional virtual image that represents a game result of the multi-player game that has progressed in accordance with changes in mallet position detected by the CCD camera and is viewed from the view point position of each player detected by the sensor, and outputs the generated image to the corresponding see-through display device. The apparatus determines the motion of each player by detecting infrared rays output from the corresponding mallet on the basis of an image captured by the CCD camera. The view point position detected by the sensor is corrected by specifying the marker in an image obtained by a camera attached to the head of each player, and comparing the marker position in that image with an actual marker position.

摘要： Whether or not an object to be rendered in stereo images is inside of a fusional area is determined on the basis of a focus point and positions of eyes of a viewer. By using characteristics of a view sight of a human in which an object in a fusional area of human eyes can be clearly recognized as a single solid, however, if an object is not in the fusional area, the object is recognized as vague overlapped images, an object which is inside of the fusional area is rendered by using an image generating algorithm capable expressing in high precision. In contrast, an object which is outside of the fusional area is rendered by using an image generating algorithm which requires lighter calculation load than the former image generating algorithm.

摘要： A two-dimensional data generator and a 2D display controller display a two-dimensional plane image based on three-dimensional data read by a three-dimensional data reading unit. A texture amount calculator calculates a texture amount used in rendering a three-dimensional image based on the three-dimensional data at each of a plurality of viewpoints set in the two-dimensional plane. A texture amount exceeding position display controller clearly displays a viewpoint where the calculated texture data amount exceeds a predetermined value in the two-dimensional plane. A texture amount adjusting unit adjusts the data amount of a desired texture.

摘要： A CG image having a transparency parameter is superimposed on a shot image, which is an image picked up by an image-pickup device, to obtain a combined image. The combined image is displayed in a combined-image-display region. In the combined image, a mask region of the CG image is set based on parameter information used to extract a region of a hand. The transparency parameter of the CG image is set based on a ratio of the size of the region of the CG image excluding the mask region to the size of the shot image. By checking the combined image, which is displayed in the combined-image-display region, the user can set the parameter information by a simple operation.

摘要： When a plurality of mixed reality (MR) experiencing persons experience the same mixed reality, there is a possibility that the experiencing persons come into contact with one another. An image processing apparatus capable of reporting to the MR experiencing persons that there is a possibility of contact. Therefore, a real space image that is image captured from the position and orientation of a user's viewpoint is drawn. The position and orientation of the user's viewpoint at this time is detected by a sensor unit. It is determined whether or not the viewpoint position is smaller than or equal to an attention distance at which there is a possibility of contact. If the viewpoint position is smaller than or equal to the attention distance, an attention display for this fact is performed.
