VEHICLE MOUNTED MONITOR

摘要

A vehicle mounted monitor comprising a lens (21) which can take a first focal length for short distance used for imaging a rain drop adhering to a vehicle, and a second focal length for long distance used for imaging the periphery of the vehicle. A camera section (2) can switch the focal length of the lens (21) between the first focal length and second focal length. A rain drop detecting section (32) detects the presence/absence of a rain drop based on an image taken by the camera section (2) with the first focal length, and a monitoring section (32) monitors the periphery of the vehicle based on an image picked up by the camera section (2) with the second focal length. Since detection of a rain drop and monitoring of the periphery of the vehicle can be carried out by one camera section, the cost and the installation space can be reduced.
