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.

Personal authentication device

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.

Image display device, image display method, and program

Provided is a method that, in the case of managing areas of a non-volatile memory of an information recording module by a file system, increases the speed of processing for writing file data and file system management information, and furthermore prevents a decrease in the rewriting lifetime of the non-volatile memory. The information recording module () is provided with a page cache control unit () that stores page cache information () in the non-volatile memory () of the information recording module () and performs control such that a specific physical block is used as a cache when writing small-sized data. Also, an access module () is provided with a page cache information setting unit () that sets information necessary for page cache control in the information recording module (). The combination of the access module () and the information recording module () prevents the execution of needless saving process with use of page caching when writing small-sized data, thereby increasing the speed of writing processing.

Access device, information recording device, controller, and information recording system

An access deviceinternally includes a logical-physical empty capacity management partfor obtaining information of a remaining capacity on a write once memory from a write once recording deviceA. In addition, the write once recording deviceA internally includes a physical empty capacity management partfor 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 devicecan 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 deviceA; and comparing the capacity with a remaining capacity on an FAT to decide an actually-recordable remaining capacity for file data.

Write once recording device

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.

Memory controller, nonvolatile storage system, and data management method

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.
