Abstract: A device has a unit acquires photograph images taken by a first and a second camera; a unit sets correspondences between positions in a first photograph image, in a first display image, in a second photograph image, and in a second display image on the basis of a first photographic line-of-sight from the first camera, a line-of-sight in the first display image based on the first photograph image, a second photographic line-of-sight from the second camera, and a line-of-sight in the second display image based on the second photograph image; and a unit generates the first display image based on correspondence with the first photograph image, generates a third display image by interpolating between the first display image and the second display image based on correspondence with the first photograph image or the second photograph image, and generates the second display image based on correspondence with the second photograph image.

Abstract: In analysis of a panorama image that is created by processing a series of picture frames, a partial image to constitute a part of the panorama image is extracted from one picture frame among the picture frames, optical flows of the one picture frame is calculated, each of the optical flows with each pixel in the partial image are associated with each other, and a distance to a subject appearing in the partial image is calculated based on the associated optical flows.

Abstract: In an image determining apparatus, a subject-shape presuming unit extracts a shape of a specified subject to be determined based on subject-area position information and structure/surface-height map information, a subject-feature-point extracting unit extracts a feature point based on the shape of the subject to be determined. Further, an otherobject-influence determining unit generates number information based on camera data, the feature point, and the height of a group of surrounding objects, an other-object-influence index calculator calculates an other-object-influence index based on the number information, and a display processor displays video picture data based on the other-object-influence index on a display device.

Abstract: Camera installation flexibility on a moving object can be increased and accuracy in identifying the moving object improved by identifying a moving object origin trajectory as a potential position at which the moving object origin exists under the following conditions: 1) A distance between the moving object origin position and a reference virtual camera is constant. 2) A direction of virtual camera VCij as viewed from the moving object coordinate system (moving object origin Om) is constant (angle formed by two lines that direct to marker Pj and to the moving object origin position Cij as viewed from the virtual camera VCij is constant.) 3) Virtual camera VCij exists on marker circle (angle between markers Pi and Pj as viewed from virtual camera VCij is constant). It is possible to identify the position of moving object M by calculating the intersecting point of each moving object origin trajectory T upon multiple trajectories of moving object origin existing.

Abstract: A vehicle image processing apparatus includes: a group of cameras; a drawing unit that converts a captured image into an image viewed along a line of sight running from a predetermined position in a predetermined direction; a viewing-line-of-sight changing unit that detects whether a first line of sight is switched to a second line of sight; and a viewing-line-of-sight generation/updating unit that acquires parameters concerning the first and second lines of sight after detecting the switching and generates a parameter which is gradually changed from the parameter of the first line of sight to the parameter of the second line of sight. Moreover, the drawing unit generates, on the basis of the gradually changed parameter, an image which is gradually changed from an image viewed along the first line of sight to an image viewed along the second line of sight.

Abstract: The position detecting device includes a travel speed detecting unit, an optical flow calculating unit, a distance calculating unit, and a position detecting unit. The travel speed detecting unit detects a travel speed of a mobile object moving on an arbitrary route. The optical flow calculating unit calculates an optical flow of one side of the mobile object, based on a series of frame images of the one side. The one side is any one of a left side and a right side of the mobile object. The distance calculating unit calculates a distance to a subject on the one side based on the travel speed and the optical flow. The position detecting unit detects a current position of the mobile object based on point data of the subject and the distance to the subject.

Abstract: A technique is provided which enables users to add, with ease, annotation information to an electronic document on a network and to share the annotation information within a disclosure range set to the annotation information. An electronic information is provided in a state that allows the electronic information to have annotation in formation attached, annotation information to be attached to the electronic information is stored, attribute information indicating the disclosure range of the annotation information is stored and, when a user requests to provide annotation information, annotation information available to the user is provided to a terminal of the user by consulting the attribute information.

Abstract: An apparatus that services a viewing record of contents includes a contents converter for a viewing record service server. The viewing record service server receives a multimedia contents distribution request from a certain user viewing terminal, and inquires an external viewing record managing server about a viewing record of multimedia contents at a user viewing terminal. The contents converter obtains the multimedia contents from a certain multimedia contents server, converts the multimedia contents into post-conversion contents that reflect the viewing record of the multimedia contents, and distributes the post-conversion contents to the user viewing terminal.
