Abstract
Conventional navigation devices are equipped with technology that supports the driving of a driver by detecting the surroundings of a vehicle using a plurality of sensors such as cameras. However, because complex arithmetic processing is carried out using the detection results from the plurality of sensors, the processing load increases and other processes requiring a rapid response can be delayed. As a result, consideration has been given to decreasing the amount of arithmetic processing and reducing the processing load by uniformly decreasing the processing area for information detected by the sensors. However, if the processing area is uniformly decreased, information necessary for driving support may not be obtained. Provided is a sensor control technology that better obtains information necessary for driving support: a sensor controller, characterized by carrying out predetermined processing by changing the processing area of the information acquired by the sensors according to the vehicle driving conditions.
