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 express the information such as camera arrangement on a map by cross-referencing information relating to a camera with the map having symbols denoting installed positions of the cameras, receiving image data in response to a picture photographed by the camera and displaying the data on a display device to allow an operator to enter the information such as camera arrangement while confirming the video image by the camera. SOLUTION: In the case that an operator selects a position of a controllable camera in a camera information dialog 720, a panning available angle with respect to a direction of a camera is displayed to allow the operator to very easily conduct panning by using a camera icon. This panning available angle can be entered on the camera information dialog 720. A main storage device stores panning available angle data. Similarly selecting the camera icon displays a camera menu and generation and deletion of the camera icon can be realized by calling a corresponding means from the menu.

摘要： PROBLEM TO BE SOLVED: To enable a user to easily grasp the state of utilizing equipment on the side of video transmission by displaying images on a monitor while synthesizing information concerning an information display device under communication connection near these images. SOLUTION: When the communication with an object video transmitter 20 is started, the video reception software of a monitoring device 60 issues a video transmission request command to the video transmission software of the video transmitter 20. Corresponding to this request command, image data transmitted by the video transmission software of the video transmitter 20 are received. When the image data are received, the frame of an image is reconstructed from a packet and displayed in a video display area by a video reception software. Next, in a mode for displaying the state of the video transmitter 20 under connection at present, the list of another monitoring device 60 displaying the image of the video transmitter 20 (video camera 10) is extracted from the header of received image data and the extracted information is synthesized and displayed with the image under display.

摘要： PURPOSE: To smoothly output a picture corresponding to the shift of a viewpoint position when the viewpoint position is moved by reconstituting a picture viewed from an observer in accordance with the given viewpoint position from plural pictures. CONSTITUTION: A corresponding point locus judgement part 12 judging a linear corresponding point locus existing when the multiple viewpoint pictures of an input multiple viewpoint picture holding part 11 are arranged in the order of viewpoints, a locus coefficient control part 13 which sequentially assumes temporary locus coefficients for groping for the coefficient of the corresponding point locus which the corresponding point locus judgement part 12 detects and calculates them and a detected locus storage part 14 storing the locus coefficient which the corresponding point locus judgement part 12 detects and the density value of the locus are provided. A judgement threshold control part 15 controls a threshold becoming a judgement reference at the time of groping for the judgement of the corresponding point locus of the corresponding point locus judgement part 12. A detected mark array holding part 16 holds addition information corresponding to an occulusion of the corresponding point locus which the corresponding point locus judgement part 12 detects. A data output part 17 outputs the corresponding point locus coefficient and the density value, which are stored in the storage part 14.
