1. An image processing device for a vehicle, comprising:
- an object detecting means for transmitting a radio wave outside of the vehicle and detecting an object in a first area outside of the vehicle by using a reflected wave of the transmitted radio wave;
an image acquisition means for acquiring an image in a second area including the first area;
an image processing means for processing the acquired image to detect, in the acquired image, the object detected by the object detecting means; and
a visibility detecting means for detecting visibility outside of the vehicle based on result of detection of the object detecting means and result of detection of the image processing means.

Abstract
An image processing device for a vehicle includes a radar for transmitting a radio wave outside of the vehicle and detecting an object in a first area outside of the vehicle by using a reflected wave of the transmitted radio wave; a camera for acquiring an image in a second area including the first area; and an image processing unit for processing the acquired image to detect, in the acquired image, the object detected by the radar. Visibility outside of the vehicle is detected based on result of detection of the radar and result of detection of the camera.
