  • Storage system including a plurality of modules having different control information
    Patent number: 8738869
    Abstract: A storage system is disclosed that stores data across plural storage devices. The storage system includes plural modules. Each of the modules includes a storage device including a data storage section that has plural slice areas to store data elements one in each, and a control-information storage section that stores control information of the plural slice areas, a communications-function section having a function of sending and receiving the data elements stored in the slice areas in the data storage section. The modules communicate with each other to replicate the data element stored in the slice area into an unused slice area in another module so as to have data redundancy.

  • Imaging apparatus, imaging method and imaging processing program
    Patent number: 7499088
    Abstract: An imaging apparatus is provided in which a picked-up image having no light-amount unevenness with respect to an arbitrary shutter speed is obtained in the case where the center of the brightness is deviated in accordance with the shutter speed. The imaging apparatus includes a shading correction center-position correction-function unit 11 which changes the center position of the shading correction by a shading correction unit 6 in accordance with the shutter speed of a mechanical shutter 2? that switches the exposure timing of the imaging by a CCD 3 or in accordance with the zoom position of a lens.

  • Searching apparatus and searching method using pattern of which sequence is considered
    Patent number: 6990487
    Abstract: A state of which a particular attribute of a record has a particular value is defined as an event. With a plurality of events and the relation of a sequence thereof, a search pattern is designated. A set of records as a search target are searched for a combination of records corresponding to the search pattern.
