20090304294IMAGE ENCODING DEVICE AND IMAGE ENCODING METHOD - An image encoding device includes a single image pickup unit generating image data by shooting a subject, an image compression unit generating digital image data by encoding the image data, a distance measuring unit measuring a distance to the subject during the shooting, and a multiplexing unit generating multiplexed data based on the digital image data and the measured distance by multiplexing distance data indicating the distance to a subject of each of given pixel blocks of the digital image data onto the digital image data.12-10-2009
20090324114IMAGE COMPRESSION APPARATUS AND IMAGE COMPRESSION METHOD - An image compression apparatus includes: first and second imaging sections for capturing an image of a subject to generate first and second image signals, respectively; first and second encoding sections for encoding the first and second image signals to generate first and second image data, respectively; first and second distance measuring sections for measuring a distance to the subject for each of image blocks, at the same time as the first and second imaging sections perform image capturing, to generate first and second distance information, respectively; first and second multiplexing sections for generating first and second multiplexed data on the basis of the first and second image data and the distance, respectively, by respectively multiplexing the first and second image data and first and second distance data, which are generated on the basis of the first and second distance information and indicate the distance to the subject for each of predefined pixel blocks in the first and second image data, respectively; and a compression processing section for reducing amounts of the first and second multiplexed data to generate compressed data. The compression processing section generates the compressed data by extracting long-distance blocks in the first and second image data on the basis of the first and second distance data, respectively, calculating a differential between the long-distance blocks in the first and second multiplexed data, and deleting the long-distance blocks in the first or second multiplexed data which are identical to their counterparts in the other multiplexed data.12-31-2009

20090092083MULTI-HOP WIRELESS NETWORK SYSTEM - A source terminal measures characteristics of the path at the source terminal itself, produces a characteristics-measurement packet, and transmits the produced characteristics-measurement packet to a relay terminal. Upon receiving the characteristics-measurement packet, the relay terminal measures characteristics of the path at the relay terminal itself, renews the characteristics of the path included in the characteristics-measurement packet using the measured characteristics of the path, and transmits the characteristics of the wireless communication path to the destination terminal. The source terminal produces an admission-request packet and transmits the packet to the destination terminal. Upon receiving the admission-request packet, the destination terminal allows or rejects the traffic quality maintenance request according to the characteristics of the wireless communication path. The allowance or rejection of the quality maintenance request is transmitted to the source terminal with the admission-reply packet by the destination terminal.04-09-2009
20090274128WIRELESS NETWORK SYSTEM - A radio device, which is the source, transmits a route request packet (RREQ) to a radio device. In response to the route request packet (RREQ), the radio device transmits to the radio device a route setup packet (RSET) including a route Radio Device Radio Device Radio Device Radio Device by looking-up topology information (TPIF). In response to the route setup packet (RSET), the radio device produces a route notification packet (RNTF) and transmits the produced route notification packet (RNTF) to radio devices, and. In response to the route notification packet (RNTF), the radio device, which is the destination, produces a route reply packet (RREP) and transmits the produced route reply packet (RREP) to the radio device, which is the source.11-05-2009
