Image Processing Device
First Claim
1. An image processing device, comprising:
- an image acquisition unit that obtains a photographic image of an area outside of a vehicle captured and output by a camera;
a sun decision unit that calculates a sun position which indicates, at least, a solar elevation and makes a decision as to whether or not the solar elevation is equal to or lower than a predetermined elevation;
an opacity detection unit that detects clouding of a lens surface of the camera;
a vehicle detection unit that detects another vehicle, different from the vehicle, based upon image information of a first image area in the photographic image; and
a control unit that suspends detection of the other vehicle by the vehicle detection unit if the opacity detection unit detects opacity in, at least, the first image area and the sun decision unit decides that the solar elevation is equal to or lower than the predetermined elevation.
