  • Publication number: 20120166713
    Abstract: An administration device includes an administration section. The administration section administers writing, reading, and erasing of data in a nonvolatile memory, in which the data can be electrically written, read, and erased and the writing and the reading are performed on a page-by-page basis and the erasing is performed on a block-by-block basis, by translating a logical address into a physical address on a per translation unit basis; and performs fold processing of increasing unwritten physical translation units by the number of written invalid physical translation units, which are contained in a block of a copy source, by copying data of written valid physical translation units among the contents of the block into a block, in which the unwritten physical translation units reside, and by erasing the block of the copy source.

  • Patent number: 8205033
    Abstract: A memory device includes a non-volatile memory which allows data to be written, read, and erased electrically and in which writing and reading are done in units of a page and erasing is done in units of a block including a plurality of pages, and a control section that manages access to the non-volatile memory. The control section performs management of access to the non-volatile memory by performing logical address-physical address translation (logical-physical translation) in translation units (TUs) each being an integer fraction of a size of the block and an integer multiple of a page size.

  • Publication number: 20110228698
    Abstract: There is provided an information processing apparatus including one host controller which communicates with other devices via multiple ports, a monitoring unit which monitors an amount of traffic for each of the ports, a processing unit which gives notification of an required amount of traffic for performing predetermined processing by a device connected to a certain port of the multiple ports, and a communication control unit which controls an amount of traffic for each of the ports, based on a required amount of traffic, notification of which is given from the processing unit, and an actual amount of traffic acquired by the monitoring unit.

  • Publication number: 20100206689
    Abstract: A paper money processor according to the present invention includes a transaction slot where paper money is at least either inserted or dispensed with an orientation such that one of lengthwise ends of the paper money is positioned at a side of a first lengthwise end of the transaction slot. The transaction slot includes a main opening which opens on a second lengthwise end of the transaction slot, and a lateral opening which is continuous with the main opening, and opens on a first widthwise end of the transaction slot.

  • Publication number: 20100061707
    Abstract: In a high speed image capturing state, a camera signal processing circuit is not needed to perform a signal process at a high screen rate, but at a regular screen rate. In the high speed image capturing mode, raw data of 240 fps received from an image sensor 101 are recorded on a recording device 111 through a conversion processing section 201 and a recording device controlling circuit 210. Raw data that have been decimated and size-converted are supplied to a camera signal processing circuit 203 through a pre-processing circuit 202 and an image being captured is displayed on a display section 112 with a signal for which a camera process has been performed.

  • Publication number: 20060012808
    Abstract: The present invention relates to an image processing apparatus and method in which more faithful colors are reproduced and noise is reduced, and to a method of manufacturing the image processing apparatus. A four-color color filter 61 is formed of a total of four filters, that is, an R filter that allows only red light to pass through, a B filter that allows only blue light to pass through, and a G1 filter that allows only green light in a first wavelength band to pass through, and a G2 filter, having a high correlation with the G1 filter, that allows only green light in a second wavelength band to pass through, the four filters defining a minimum unit. The G1 filter and the G2 filter are arranged at mutually diagonal positions within the minimum unit. RGB signals are generated in accordance with four kinds of signals which are transmitted through the four-color color filter 61 and which are obtained by an image sensor.
