Disclosed is an image display device capable of recognizing a hand of a user and predefining an operating region. Image recognition means recognizes the position of a hand of the user. Operating region setup means predefines the operating region, on an imaging region plane of imaging means and around a position on which the user's hand is projected, for the purpose of enabling the user to issue instructions to the image display device. When the position on which the user's hand is projected moves and comes close to the periphery of the operating region, the operating region setup means moves the operating region in the direction of the movement of the position on which the user's hand is projected. Further, the image recognition means recognizes a hand-waving motion of the user, whereas the operating region setup means sets the size of the operating region in accordance with the magnitude of the user's hand-waving motion. Consequently, the image display device provides increased ease of operation and makes it possible to define the operating region in accordance with a user's intention without imposing a significant processing load on itself.

Image display device and display control method thereof

A wireless IC memory, for improving the security thereof, for achieving protection of business information and privacy, comprises an RFID tag, wherein it is possible to setup 'readout disenabling (ReadLock)' condition to the UII code bank for storing ID data of the RFID tag, with a predetermined protocol from an external communication apparatus, within the RFID tag. Setup of 'readout disenabling (ReadLock)' condition is stored on a readout enabling/disenabling condition memory portionwithin the RFID tag. In case where the &#x201c;readout disenabling (ReadLock)&#x201d; condition is set up in the UII code bank, a protocol process controller portionof the RFID tag, not responding the UII code, normally, but answers a fake UII code or an error code, or gives no answer, to a request or command of readout of the UII data from the external communication apparatus.

A hierarchical structure is established among a plurality of RFID tags, such that ID numbers can be read only from RFID tags which belong to a particular layer. RFID tag can control whether permission should be given to read its ID number therefrom to protect the ID number. Data held in the RFID tag can be read from the outside. RFID tag comprises a memory circuit having a function of holding data, and a logic circuit having a function of processing a control command received from outside. Memory circuit stores an own ID number for identifying the RFID tag itself, and a parent ID number for identifying a second RFID tag. When RFID tag receives an ID number read command which contains first data as a parameter from outside, the logic circuit outputs the own ID number to outside only when the first data matches the parent ID number.

An RFID device is capable of stopping and restarting a response via a response stop command. The device is capable of initializing a part of or the whole of internal data including a response restart set data storage portion. The device is capable of using command data from an external communication equipment to look up response restart data at the restart of a response, deciding a data storage area and content that may be initialized when the restart is possible, and rewriting a data storage portion.
