A receiver apparatus capable of retaining the quality of video images received through complexity-reduced small-load processing without having to depend upon its associated transmitter device. In cases where an instruction is made for receiving streaming data in the process of performing the processing of download data, when the loss of such streaming data is predicted to increase in such a way as to go beyond a predetermined degree if both the processing of download data and the processing of streaming data are performed at a time, the receiver performs the processing of the streaming data by giving thereto a higher level of priority.

A fuel shut-off valve includes a casing, an ascendable and descendible float, and an upper valve element, which is actuated by the float to open and close connector passage that communicates the inside of fuel tank with the outside, and which includes a valve body and a ring-shaped seat member. The ring-shaped seat member makes a connector bore, which communicates with the connector passage, therein, and includes a base, a holding portion, a seating portion, a lip-shaped portion, and a thin-film-shaped portion. The seating portion opens and closes the connector passage, and defines an opening of the connector bore. The lip-shaped portion seats on and separates away from the float, and defines the other opening of the connector bore. The thin-film-shaped portion is disposed between the base and the lip-shaped portion, and is deformable elastically upon being pressed by the float when the float seats on the lip-shaped portion.

摘要:
An image processing system and the like capable of recognizing a lane mark in a road image with high accuracy are provided even if a light illumination state on a road surface is partially different. According to the image processing system (100) mounted on a vehicle (10), a color component (Rij, Gij, Bij) of the first pixel (Pij) included in an area (Aij) set in the road image is corrected with reference to a color component (Rik, Gik, Bik) of a second pixel (Pik) in view of a fact that it is highly probable that the color component of the second pixel included in the area along with the first pixel is affected by a shadow or light on the road surface. This reduces the effect of the shadow or light on the road surface and the actual color of a road surface portion corresponding to the first pixel can be sufficiently reflected in the color components (Rij, Gij, Bij) of the first pixel (Pij) and consequently in a feature value (Qij). Therefore, a lane mark (M) and its edge (E) are recognized in the road image on the basis of the feature value (Qij) of each pixel (Pij) in the road image.
摘要:
A lane recognizing device comprises: an image processing means which performs a process of estimating a lane of a road by processing an image of the road and outputs a result of the process as first lane information; a lane estimating means which performs a process of estimating the lane using a map data of the road and the current position information of a vehicle and outputs a result of the process as second lane information; and an actual lane recognizing means which recognizes an actual lane of the road on the basis of the first lane information and the second lane information. Thereby, even if there is an unpredictable skid mark or road repaired part, it is possible to detect the lane accurately while increasing the opportunities for detecting the lane as much as possible by processing the road image and obtaining the road information and the map data.
