摘要:
A first face detecting section detects the face of a passerby based on an image obtained from a first camera set to be easily recognized by the passerby. A second face detecting section detects the face of the passerby based on an image obtained from a second camera set so that the camera will be difficult to be recognized by the passerby. A classifying section classifies the passerby based on the detection results of the faces by the first and second face detecting sections and adjusts a threshold value for authentication based on the classification result. The face collating section calculates the similarity between the face of the passerby and each of faces of registrants and determines whether the passerby is a registrant or not according to whether the degree of calculated similarity is not lower than the adjusted threshold value for authentication.

A person searching device stores beforehand, as history information, biometric information and a person searching result with respect to the biometric information, and judges with respect to each history information whether or not the biometric information of a person to be searched and the biometric information of the history information are of the same person. The person searching device judges the person searching result with respect to the person to be searched based on the searching result in the history information of the biometric information judged to be of the same person as that of the biometric information of the person to be searched, in a case where there exists the history information of the biometric information judged to be of the same person as that of the biometric information of the person to be searched.

A data writing method is disclosed. In a memory system comprising a NAND flash memory and a controller which controls the memory, the memory system storing data provided from a host to the NAND flash memory, the data writing method comprises a steps of specifying a column address in which a column failure which has occurred in the NAND flash memory by the controller, and a step of, during writing into the NAND flash memory, writing data of a first logic level into a memory cell which corresponds to the specified column address regardless of write data provided from the controller.

In an image compression device, an image input section performs image input processing to input an image having characteristics which are recognition objects, a conversion processing section performs conversion processing to convert a pixel value of each pixel forming the image into a pixel value suitable for coding while retaining the characteristics which are the recognition objects in the image input by the image input processing, and a coding section performs coding processing as compression processing with respect to the image constituted of each pixel converted by the conversion processing.

摘要:
A memory card includes a controller and a nonvolatile semiconductor memory. The controller manages a correspondence between a first address in a semiconductor memory of a first erase block size and a second address in a semiconductor memory of a second erase block size other than the first erase block size. The nonvolatile semiconductor memory is a memory of the second erase block size. The controller executes access to the nonvolatile semiconductor memory by the second address.
摘要:
A first illumination section radiates light at a certain degree of illuminance toward the face of a human recognition object from an upper right part or an upper left part of a camera, and a second illumination section radiates light at a certain degree of illuminance toward the face of the human recognition object from a lower part of a camera. The camera photographs and inputs a facial image of the human recognition object. The image processing section extracts a feature value of the face of the human recognition object from a facial image inputted by the camera and collates the feature value extracted with a standard feature value registered in advance so as to recognize a facial image of the human recognition object.
摘要:
In a data storage system using a flash memory unit and an HDD, the storage area of the flash memory unit is logically divided into a permanent storage area, a non-volatile cache area, which are used as cache memory areas of the HDD, and a high-speed access area. These divided areas are individually managed. The permanent storage area stores data which is used frequently for a relatively long time period. The non-volatile cache area is used as an ordinary cache memory area in which data, which is updated relatively frequently, is stored. The high-speed access area is a storage area to be used by, e.g. an operating system (OS) of a host system. For example, a swap file, which needs to be accessed at high speed, is shifted into the high-speed access area.
