  • Publication number: 20130329068
    Abstract: In the case of a conventional image apparatus that generates refocus image on the occasion of image display, there is a waiting time because the image apparatus generates the refocus image in response to an operation of a user and requires the time to generate the refocus image. To address this situation, an image apparatus determines ranks of targets to be in focus based on history information indicating operation history, and generates sequentially combined image data from multi-viewpoint image data obtained by capturing images from multiple viewpoints, by focusing on the targets in accordance with the determined ranks.

  • Patent number: 6078337
    Abstract: In a system in which a plurality of nodes are connected using a light wavelength multiplexing connection route which can simultaneously connect nodes using light beams of a plurality of different wavelengths, each node has a cache memory for holding data in memories in other nodes. Some or all of the pieces of information required for data transfer in one node or between the nodes are transferred from the node to an arbiter used in use arbitration of the connection route via one of arbitration optical signal routes for respectively connecting the arbiter and the nodes. The arbiter distributes the transferred information to other nodes, and each node updates the contents of its cache memory on the basis of the distributed information.

  • Patent number: 6021472
    Abstract: An operation for achieving consistency among copies existing in a plurality of cache memories in a parallel computer system was performed per transaction. If an access issued from a processor to a cache memory is a synchronous access, seeking of a DIRTY block in the cache memory is started. The cache memory issues a bus transaction onto a system bus and performs write back of the DIRTY block in the cache memory relative to a main memory. The write back bus transaction issued from the cache memory in the foregoing fashion is snooped by the other cache memory. With this arrangement, an unnecessary consistency holding operation can be omitted to reduce a delay upon memory accessing in a parallel computer system employing a loose memory consistency model.
