摘要： This invention can make data communications at an optimal transfer rate on the basis of the unarrived data volume on a network between two end terminals. For this purpose, a transmitting terminal (1-1) adds sequence number information to data generated by a data generator (1-11), and transmits the data to a receiving terminal (1-2) via a data transmitter (1-12). Since the receiving terminal (1-2) transmits data including the sequence number in the received data, the transmitting terminal determines that data (buffer capacity) corresponding to the difference between the current sequence number and the received sequence number remain on the network and calculates that volume using a network buffer data volume calculator (1-14) The transmitting terminal determines the transmission rate on the basis of the calculation result, and controls the data transmitter (1-12) to transfer data at that transmission rate.

摘要： Data can be transmitted efficiently by sending control information as demanded by the status of a network. To accomplish this, a transmitting terminal transmits data using the Real-Time Transport Protocol (RTP), and control information, which is for ascertaining the status of the network, is transmitted by both the transmitting terminal and a receiving terminal using the Real-Time Transport Control Protocol (RTCP). The transmitting terminal transmits the control information as an RTCP packet at predetermined time intervals. If the transmission rate does not attain a target rate, however, the transmitting terminal raises the transmission rate by a predetermined percentage regardless of the predetermined time intervals. If it is judged that transmission loss has occurred based upon the control information sent from the receiving terminal, the transmitting terminal lowers the transmission rate by a predetermined percentage regardless of the predetermined time intervals.

摘要： Position and orientation information indicating the relative position and orientation relationship between the viewpoint of the observer and a physical space object on a physical space is acquired. A virtual space image is generated based on the acquired position and orientation information, and is rendered on a memory. A physical space image of the physical space object is acquired. By rendering the acquired physical space image on the memory on which the virtual space image has already been rendered, the physical space image and the virtual space image are combined. The obtained composite image is output.

摘要： An OCT apparatus that photographs with a plurality of measuring beams concurrently has a mechanism for adjusting the optical path length of a reference beam for each measuring beam. Accordingly, when tomographic images photographed in this manner are displayed side by side, because the depth of photographing varies from one tomographic image to another, it is difficult for an operator to comprehend the positional relation between the photographed images. In displaying tomographic images acquired with a plurality of measuring beams, the display position of each tomographic image is adjusted based on the changed optical path length of a reference beam of the measuring beam used for the image. The tomographic images are thus aligned in height and are presented in a manner that is easy for the operator to comprehend the positional relation between the photographed images.

摘要： By applying identification processing to each index included in a captured image, a set of an identifier, image coordinates, and an image number is acquired for each index, and the acquired set is registered in a data saving unit. The data saving unit manages the numbers of times of previous identification for respective identifiers. A display unit displays the number of times managed in association with an identifier in a set to be registered every time the set is registered. An index position and orientation calculation unit calculates the positions and orientations of indices corresponding to a set group using the set group registered in a memory.
