Abstract: A distribution control apparatus is connected to a communication terminal via a network. The distribution control apparatus includes a receiving unit, a whiteboard control unit, a whiteboard unit, and a transmitting unit. The receiving unit receives, from the communication terminal, operation data representing an operation performed by a user. When the operation is a stroke command, the whiteboard control unit stores a series of coordinates entered onto the communication terminal and contained in the operation data in a first storage unit and generates stroke data representing a stroke from the stored coordinates. The whiteboard unit stores the generated stroke data in a second storage unit and generates video data by rendering the stroke data. The transmitting unit transmits, to the communication terminal, converted video data that is obtained by converting the generated video data into a data format that allows distribution.

Abstract: A disclosed contents management system includes a management server for managing contents and an information processing device for performing a process on the contents, which are connected to a network. The management server includes a supplying unit for supplying the contents to the information processing device in response to a request from the information processing device. The information processing device includes an acquiring unit for acquiring reproduction starting point information of the contents, a generating unit for generating, based on the reproduction starting point information acquired by the acquiring unit, link information for accessing the contents, and a storing unit for temporarily storing, in a region of a memory, the link information generated by the generating unit in association with information indicating content of the contents, when a pasting unit pastes the link information onto document data being edited.

Abstract: In a shared memory multiprocessor system, data reading accesses and data write-back completion notifications are selected in synchronism with all of the nodes to order them. In each of the nodes, a subject address of ordered data reading access is compared with a subject address of ordered data write-back completion notification to detect a data reading operation of the same address which is passed by the completion of the data writing-back operation. Both a data reading sequence and a data writing-back sequence are determined. At this time, such a coherency response for prompting a re-reading operation of the data is transmitted to the node which transmitted the data reading access, so that coherency of the data is maintained.

Abstract: An image pickup apparatus for picking up an image of a target object in divisions as a plurality of partial images which overlap by a predetermined quantity, is provided with a field angle setting unit configured to set a field angle with which the target object is to be picked up, a display unit for displaying an image, and an image generating unit for generating the partial images to be displayed on the display unit by dividing an image of the target object which is picked up with the field angle.

Abstract: In image processing method and apparatus of the present invention, image distortions caused by oblique imaging are corrected. A feature point of one of a plurality of partially overlapping images corresponding to a common location of an original image, shared by the plurality of partially overlapping images, is determined. A matched point of one of the other partially overlapping images corresponding to the feature point is determined so that a direction of the object plane is calculated based on the feature point and the matched point. One of the plurality of partially overlapping images is selected as a standard image whose image distortions are to be corrected. A distortion-corrected image is generated on a projection plane by projecting the standard image onto the projection plane based on the direction of the object plane such that image distortions in the standard image are eliminated.

Further, a shape calculator calculates a shape of the object based upon the captured image data, captured attitude information, a translation component, and the correspondence of the characteristic points. The motion detector may further include acceleration sensors and angle speed sensors. A disturbance detector may further be provided to detect a disturbance in acceleration signals output by the acceleration sensors and a disturbance in magnetic signals output by the magnetic sensors.

Abstract: In image processing method and apparatus of the present invention, an image distortion caused by an oblique image pickup is corrected. A plurality of images of an object on an object plane are input, the plurality of images including at least a pair of partially overlapping first and second images that are taken at two viewpoints, the first and second images sharing a common location on the object plane. A feature point of the first image corresponding to the common location and a matched point of the second image corresponding to the feature point of the first image are determined. A direction of the object plane is calculated based on the feature point and the matched point. A distortion-corrected image on a projection plane, which is parallel to the object plane, is generated by projecting one of the first and second images onto the projection plane based on the direction of the object plane through a perspective projection.

Abstract: The image input apparatus comprises the image pickup unit which optically scans a subject and successively acquires partial images of the subject. The relative change detection unit detects an amount of relative change in position or speed of the image pickup unit between a time when a previous partial image was taken and a time when a current partial image is being taken. The an overlapping amount calculating unit calculates an amount of overlap between the previous partial image and the current partial image based upon the amount of relative change in position or speed detected by the relative change detection unit. The image recording determination unit determines whether or not the current partial image is to be recorded based upon the amount of overlap calculated by the overlapping amount calculating unit.

Abstract: A video data reproduction apparatus displays an animation on a display by receiving and reproducing video data through streaming data communication. A memory stores index image generated from the video data corresponding to a video display time. The index image represents a part of an image created by the video data.
