20130002874 | SURROUNDING AREA MONITORING APPARATUS FOR VEHICLE - A surrounding area monitoring apparatus for vehicle includes an infrared camera mounted on a vehicle for capturing images of surrounding area around the vehicle, a unit for generating and displaying images based on image data captured by the camera, and a controller for calibrating output of the camera with respect to a relation between pixels, based on image data produced by imaging a surface of a shutter that opens and closes an aperture introducing a light to the camera. The controller estimates whether a temperature of the camera is stable, based on an operation state of the vehicle, and determines a possibility that a driver is looking at the unit, based on a behavior of the vehicle. When the temperature of the camera is estimated stable and the possibility that the driver is looking at the unit is determined to be low, the means for calibrating executes the calibration. | 01-03-2013 |
