Claim One:
1. An image processing device for a vehicle, comprising: means for detecting an object by transmitting a radio wave outside of the vehicle and detecting the object in a first area outside of the vehicle by using a reflected wave of the transmitted radio wave, the object detecting means detecting a distance from the vehicle to the detected object in the first area outside of the vehicle by using the reflected wave of the transmitted radio wave; means for acquiring an image in a second area including the first area; means for processing the acquired image to detect, in the acquired image, the object detected by the object detecting means, the image processing means executing frequency analysis of brightness distribution in the acquired image; means for detecting visibility outside of the vehicle based on the result of the detection of the object detecting means and the result of the detection of the processing means; and means for estimating a visibility distance outside of the vehicle based on the detected distance and the result of the frequency analysis.
