Abstract: The present invention relates to a lane-dividing line detection device and has an object of detecting a lane-dividing line with high accuracy by accurately extracting characteristic points of the lane-dividing line while responding flexibly to road surface conditions. According to the present invention, pixel parts where a brightness variation is larger than a predetermined threshold are extracted from an image picked up by a camera that picks up an area ahead of a vehicle as edge points representing the lane-dividing line on a road surface (step 106).

Abstract: In a multipoint mesh network, communications for establishing the network between multiple communication terminals may be coordinated such that connection request signals are not transmitted from both terminals in a pair of terminals to each other. In one example, a multipoint connection start terminal may be configured to request connections with each of the communication terminals participating in the mesh network. The multipoint connection start terminal may then receive a connection permission signal from each of the terminals to which a request signal was sent. The multipoint connection start terminal may subsequently generate terminal designation information specifying which terminals are to request connections with which other terminals so as to avoid communication overlap. This terminal designation information may then be transmitted to each of the other communication terminals participating in the mesh network.
