摘要： PURPOSE: To attain optional movement of visual point in a space by receiving an image from plural visual point positions, detecting a position and a direction of eyes of image viewer, and configuring an image seen from the visual point positon again from multi-visual point image data based thereon. CONSTITUTION: A virtual image is configured again by forming a virtual image pickup point Vp being a visual point of a viewer by using images picked up on line segments l0 , l1 , l2 . A picture element value of a virtual image Vu formed by using the point Vp to be a virtual image pickup point is the same value as a picture element value of an image Ru obtained by image pickup while using a cross point Rp of the line segments l0 , l1 , l2 as an image pickup visual point being a center of a lens. In order to obtain the virtual image Vu, a ray is traced in the unit of picture elements in this way and values of the picture elements constituting the virtual image Vu are to be decided one by one. An image in the optional visual point position and in the direction of line of sight is configured again from the image picked up from a limited image pickup visual point to attain optional visual point movement in a space.

摘要： PROBLEM TO BE SOLVED: To allow the user side equipment to acquire information on the management state of control right and to improve the operability by indicating it to the user in the remote camera control system that manages a control request relating to the camera from a plurality of user equipments. SOLUTION: In the system that includes a server to which a camera is connected and a client controlling remotely an image pickup condition of the camera, the server generates a message denoting a state relating to a camera control right as to each client and issues the message to each client. When the client side discriminates it that the received message is a message denoting a state relating to camera control, the client acquires and stores the state of the control right and its valid time from the message and stores the reception time of the message (steps S301, 302, 305, 306). Then the client displays the state of the control right and its remaining time based on the stored information and the current time.

摘要： PURPOSE: To accurately form a picture observed from a visual point different from respective visual points in a multi-visual point picture by the use of an epipolar plane image(EPI). CONSTITUTION: One object is photographed by four cameras 20 to 23 arranged on respectively different photographing positions (visual point positions) to obtain four multi-visual point pictures, a line on the same positions of respective pictures is detected to prepare an EPI, points corresponding to a given point on an object is detected from the EPI, and a picture to be obtained from a visual point position different from respective visual point positions is formed from these correspondence points by the use of interpolation. When both of an RGB display color system and an HVS (hue, brightness of color and saturation) display color system are used for the detection of correspondence points, the reduction of accuracy for the detection of the correspondence points due to the mirror reflection of an object can be removed.

摘要： PURPOSE: To provide a moving image retrieving device capable of reducing the quantity of inputted annexed information and simply changing the annexed information. CONSTITUTION: An information processing system 10 to be the moving image retrieving device is provided with a central processing unit(CPU) 1, an input device 2, an output device 3, a data base 4, a storage device 5, and a system bus 6. The data base 4 stores tree structure and annexed information. A moving image is retrieved by adopting the addition of annexed information to each node of tree structure as a prerequisite and the retrieval of a moving image scene is regarded as equivalence to the retrieval of a node in the tree structure. The tree structure holds an attribute for generally recording connection relation in each node and recording annexed information, a node name, etc. Information added to each node constituting the tree structure is succeeded in order from a top node to lower nodes. When said processing is executed before retrieval or after inputting all annexed information, the annexed information added to the tree structure can be hierarchically managed. Since the annexed information is succeeded to respective nodes of the tree structure, keyword retrieval can be executed by using a conventional retrieving method.

摘要： PROBLEM TO BE SOLVED: To easily make the three-dimensional model of a real object. SOLUTION: The three-dimensional model of a object used for synthesizing a computer image showing a virtual world to the image showing a real world and included in the image showing the real world is set by using an adjusting display in this method of processing information. The image which shows the real world including the object obtained from a plurality of viewpoints is acquired. The three-dimensional model corresponding to the object is synthesized to the images showing a plurality of real worlds respectively based on the space positional informations of the images showing a plurality of real worlds and the positional information of the three-dimensional model corresponding to the object. The three-dimensional model is made to display on the adjusting display. An user adjusts the position and the shape of the three-dimensional model corresponding to the object on the synthetic image by a manual instruction based on a plurality of synthetic images.

摘要： PROBLEM TO BE SOLVED: To solve the problem on a portable terminal using a HMD (Head Mount Display), which has a screen output projecting on the HMD, that the field of view of a user is blocked by the HMD and so the operation of an input device such as a keyboard in done with blind touch which often causes input errors. SOLUTION: To solve the problem, a virtual input device is displayed on the HMD and keys of the keyboard that the user touches are displayed. A touch sensor is arranged on the surface of the keyboard for discriminating which key the user touches. The discrimination result is displayed on the HMD for visible identification of which key he touches before actual key input.

摘要： PROBLEM TO BE SOLVED: To prevent wasteful power consumption. SOLUTION: A display part such as a display panel is arranged inside of the device, and an image displayed on the display part is arranged so as to be looked into a window part 101a. When a head part approaches to this window part 101a to look into the image, a sensor 103A is turned on and a power source of the device is turned on. And, when the head part is left from the window part 101a, the sensor 103A is turned off and the power source is also turned off. Since the power source of this device is automatically turned on-off by the sensor 103A, it can be prevented to forget switching off the power source. As a result, it is possible to prevent wasteful power consumption caused by forgetting to switch off the power source.
