Abstract: A personal authentication device includes an infrared ray emitter that emits infrared rays, an infrared camera that captures an infrared image, a status signal outputter that outputs a signal related to a status of the personal authentication device or the status of surroundings of the personal authentication device, and a controller. The controller determines whether or not there is a predetermined change in the status of the personal authentication device or the status of the surroundings of the personal authentication device based on a signal output from the status signal outputter, and when there is the predetermined change, the controller drives the infrared ray emitter and the infrared camera, and performs a three-dimensional face authentication process based on the infrared image captured by the infrared camera.

Abstract: An image display device includes a display that displays at least one of a visible image of an object and a thermal image that represents temperature information of the object by a color and a control unit that controls the display. The control unit causes the display to display one of a first image and a second image. The first image includes the thermal image and the visible image. The second image does not include the visible image but includes a thermal image that is more enlarged as compared to the thermal image in the first image with a numerical value indicating a temperature being superimposed for each predetermined region on the thermal image in the second image.

In addition, the write once recording device 2A internally includes a physical empty capacity management part 27 for managing a remaining capacity on the write once memory and notifying the access device of the capacity. Prior to recording of file data, the access device 1 can know an accurate remaining capacity of the write once recording device by: obtaining a remaining capacity of the write once memory from the write once recording device 2A; and comparing the capacity with a remaining capacity on an FAT to decide an actually-recordable remaining capacity for file data.

Abstract: In a memory controller according to the present invention, an external I/F unit receives ID information associated with data from the outside of a non-volatile memory, and a recording controller manages a recording position of the data in the non-volatile memory based on the ID information, so that an amount of time necessary for the retrieval of rights information based on the ID information is reduced.

Abstract: A memory controller, a nonvolatile storage device and a nonvolatile storage device system are provided, in which the matching check between content data and meta data can be simplified, a starting time can be shortened, and further, a host device side can provide users with a common GUI without being conscious of the Usage Rule including an encryption method for copyright protection and a copyright protection method and a content management. A write status holding unit that holds write status information to identify the content data being written, and a content management unit that manages the content data and the meta data are included. The content management unit eliminates mismatch between the content data and the meta data based on the write status information. Further, a GUI script generating unit is included which generates a script describing the screen display contents in accordance with a request from the host device for the content data.

Abstract: A memory controller (220) that controls the writing of data into or the reading of data from a non-volatile memory (230) includes a host interface unit (210) and a host information management unit (223). The host interface unit (210) receives an application ID identifying an application used when recording user data into the non-volatile memory (230) and a device ID identifying an external device (100) that uses the stated application. The host information management unit (223) records a host information table indicating a correspondence relationship between the application ID and the device ID into the non-volatile memory. The memory controller (220) can thus easily determine by what data processing device the data stored in a non-volatile storage device (200) attachable to/removable from the external device (100) has been updated.

Abstract: In a file system such as an FAT file system, clusters are linked only in the forward direction. To perform seeks to clusters in the reverse direction, links need to be followed from the beginning side of the file data in every seeking operation. When a large amount of data is subjected to such reverse seeking, the overhead will be particularly large. A memory controller (101) for controlling data writing or reading to or from an information recording medium includes a control unit (105) that detects continuity of data in an address space of a file system managing data that is recorded into the information recording medium and a data-continuity management unit (103) that stores information about the continuity of the data as data-continuity information.

Abstract: A file system (105) and a nonvolatile memory device (101) notify each other of the cluster size and the logic block size respectively in advance. In writing, the file system notifies the nonvolatile memory device of data as to which cluster of the file system can be discarded in the logical block of the nonvolatile memory device. With this, the nonvolatile memory device can avoid the copy of data at the writing, so that the nonvolatile memory device is not required to continuously keep data of an unnecessary file.
