20100254349WIRELESS COMMUNICATION SYSTEM AND WIRELESS COMMUNICATION METHOD TO PERFORM HANDOVER OF COMMUNICATION USING DIFFERENT COMMUNICATION SYSTEMS - Disclosed is that when the first wireless communication apparatus is connected to a terminal apparatus such as a wireless access point wirelessly, the second wireless communication apparatus performs the communication with the first wireless communication apparatus by a short distance wireless communication, then the first wireless communication apparatus transmits participation information to participate in the network to the second wireless communication apparatus by the short distance wireless communication, and the second wireless communication apparatus is connected to the network based on the received participation information so as to communicate with the first wireless communication apparatus through the terminal apparatus.10-07-2010
20100296434WIRELESS COMMUNICATION SYSTEM AND WIRELESS COMMUNICATION METHOD FOR SWITCHING WIRELESS CHANNELS - In a wireless communication system including a plurality of wireless terminal apparatuses and a relaying apparatus, the relaying apparatus performs a channel search to select a wireless channel in a good communication situation when the relaying apparatus transmits a beacon signal at a constant period, and transmits switching destination information to be used to switch the wireless channel to the selected one in a state of being stored in the beacon signal. When the communication situation of the wireless channel has deteriorated, the relaying apparatus switches the wireless channel being used by the communication section to the selected one based on the switching destination information. When the communication situation of a wireless channel of the wireless terminal apparatus has deteriorated, the wireless terminal apparatus switches the wireless channel to the selected one based on the switching destination information.11-25-2010
20100311330WIRELESS COMMUNICATION SYSTEM FOR COMMUNICATION HANDOVER BY USING DIFFERENT COMMUNICATION MODES - A wireless communication system includes a terminal device; a first wireless communication device; and a second wireless communication device. When the first wireless communication device communicates with the second wireless communication device by wireless LAN communication after a handover and completes prescribed processing to the second wireless communication device, the first wireless communication device sends first disconnection information to the second wireless communication device to disconnect the second wireless communication device. The second wireless communication device stores wireless LAN connection information before communicating with the first wireless communication device by the wireless LAN communication when the second wireless communication device is connected with the terminal device at a time of the handover. The second wireless communication device disconnects the first wireless communication device and connects with the terminal device based on the wireless LAN connection information when the first disconnection information is received.12-09-2010
20110058713DIGITAL PHOTO FRAME, CONTROL METHOD AND RECORDING MEDIUM WITH CONTROL PROGRAM - A digital photo frame including a display section capable of sequentially displaying at least two digital photographs judges the facial expression of a person viewing a digital photograph displayed in the display section, and information related to this judged facial expression is stored in association with the digital photograph being displayed. Also, when stored digital photographs are to be displayed, information related to a facial expression stored in association with each digital photograph and a judged facial expression of a person are compared, and the display of each stored digital photograph is controlled based on the comparison result.03-10-2011
20110071832IMAGE DISPLAY DEVICE, METHOD, AND PROGRAM - It is an object of the present invention to make an act of viewing an image interactive and further enriched. A microphone 03-24-2011
20110072040IMAGE DISPLAY DEVICE, METHOD, AND PROGRAM - It is an object of the present invention to search for image data with an intuitive operation to which active elements are added.03-24-2011
20110074656DISPLAY TERMINAL PROVIDED WITH AN IMAGE DATA SHARING FUNCTION, IMAGE SHARING SYSTEM AND METHOD FOR SHARING IMAGE DATA - A display terminal that performs image display processing for displaying in a display section image data recorded in a recording section, which includes a controlling section that performs image sharing processing for providing image data recorded in the recording section to another display terminal over a network, acquiring image data recorded by another display terminal over the network, and displaying the acquired image data in the display section, and sharing control processing for performing control to select image data recorded by another display terminal set up at a location whose distance from the setup location of the display terminal satisfies a predetermined condition, as target image data for the image sharing processing.03-31-2011

20100311348WIRELESS COMMUNICATION DEVICE AND WIRELESS COMMUNICATION METHOD FOR DETECTING FIELD INTENSITIES OF WIRELESS CHANNELS - A wireless communication device includes a communication unit, a detection unit, and a control unit. The communication unit communicates with another wireless communication device by use of a wireless channel selected from wireless channels. The detection unit detects field intensities of first wireless channels. The control unit calculates a field intensity of a second wireless channel based on the field intensities of the first wireless channels, wherein the first wireless channels do not include the second wireless channel.12-09-2010
20100322209WIRELESS COMMUNICATION APPARATUS AND WIRELESS COMMUNICATION METHOD FOR DETECTING ELECTRIC FIELD INTENSITY OF WIRELESS CHANNEL, AND PROGRAM STORING MEDIUM - A wireless communication apparatus includes a communication unit and a control unit. The communication unit periodically transmits a beacon signal to wireless terminal devices existing in a network using a use channel selected from wireless channels and to detect electric field intensities of the wireless channels. The control unit detects, by the communication unit, the electric field intensities of the wireless channels in a predetermined communication limiting period in a period during which wireless communication with an unspecified wireless terminal device existing in the network is prohibited in a period in which the beacon signal is transmitted.12-23-2010
20100330905WIRELESS COMMUNICATION APPARATUS AND WIRELESS COMMUNICATION METHOD FOR DETECTING ELECTRIC FIELD INTENSITY OF WIRELESS CHANNEL - A wireless communication apparatus includes a communication unit, a detection unit, and a control unit. The communication unit wirelessly communicates with another wireless communication apparatus using a first wireless channel. The detect ion, unit detects electric field intensities of wireless channels except for the first wireless channel. The control unit calculates an electric field intensity of the first wireless channel based on the electric field intensities of the wireless channels detected by the detection unit.12-30-2010
