A display control unit causes a display device to display the synthesized image in a case where the determination unit does not determine that the error region exists in the synthesized image, and causes the display device to display the physical space image in a case where the determination unit does determine that the error region exists in the synthesized image.

Head mounted display and display for selectively displaying a synthesized image and a physical space image, and control method thereof

If the size of an error portion within an image of the frame of interest is equal to or larger than a threshold and it is determined that no error portion exists within an image of a frame immediately before the frame of interest, a display unit () is caused to display the image of the frame immediately before the frame of interest as the image of the frame of interest. If the size of an error portion within the image of the frame of interest is smaller than the threshold and it is determined that an error portion exists within the image of the frame immediately before the frame of interest, the display unit () is caused to display a result obtained by correcting the error portion within the image of the frame of interest using a pixel group surrounding the error portion.

Head mounted display, display, and control method thereof

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.

Image processing apparatus and method with setting of prohibited region and generation of computer graphics data based on prohibited region and first or second position/orientation

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 ( - ) adds sequence number information to data generated by a data generator ( - ), and transmits the data to a receiving terminal ( - ) via a data transmitter ( - ). Since the receiving terminal ( - ) 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 ( - ) The transmitting terminal determines the transmission rate on the basis of the calculation result, and controls the data transmitter ( - ) to transfer data at that transmission rate.

Data communication apparatus and method

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.

An information processing system has a plurality of nodes each including one or more CPUs that utilize monitoring of a common bus, wherein the plurality of nodes are connected to one another by a connection path that cannot monitor information on an internal bus in each node. Information required to perform synchronized operation in a node or among nodes is transmitted to an arbiter via an optical fiber serving as a transmission path different from the connection path, and part of this information is again distributed from the arbiter to each of the nodes based upon the information. The system operates in such a manner that the information is reflected in its own node based upon the re-distributed information. Further, in order to perform the synchronized operation among CPUs based upon the re-distributed information, the system controls the information to be distributed from each node to arbiter. Thus, when an operation for maintaining synchronization among CPUs is performed, the present invention enables the system to reduce processing which accompanies synchronizing operation by CPUs across nodes and improve the processing capability of the entire system.
