Abstract
Abstract A road image input system for controlling an automotive vehicle includes a pick-up mounted on the vehicle for picking up the image of a road ahead of the traveling vehicle, a sensor for sensing the traveling condition of the vehicle, and an image processor for obtaining information indicative of the road by setting an image processing window on the image which has been picked up and processing data contained within the image processing window. The image processing window is set at a position based on values of the vehicle velocity and the steering angle of the steering wheel.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
92 words
A road image input system for controlling an automotive vehicle, comprising: pick-up means mounted on the vehicle for picking up an image of a road ahead of the vehicle; sensing means for sensing the traveling condition of the vehicle; and image processing means for obtaining information indicative of the road by adjusting the position of an image processing window in the x- and y-directions according to the output of said sensing means on a part of the image which has been picked up and processing data contained within said image processing window.
Claim 2
Dependent Claim
92 words
A road image input system for controlling an automotive vehicle, comprising: pick-up means mounted on the vehicle for picking up an image of a road ahead of the vehicle; sensing means for sensing the traveling condition of the vehicle; and image processing means for obtaining information indicative of the road by adjusting the position of an image processing window in the x- and y-directions according to the output of said sensing means on a part of the image which has been picked up and processing data contained within said image processing window.
Claim 3
Dependent Claim
22 words
The system according to claim 1, wherein said sensing means comprises: means for sensing vehicle velocity, and means for sensing steering angle.
Claim 4
Dependent Claim
43 words
The system according to claim 1, wherein said image processing means comprises: means for setting a reference image processing window, and arithmetic means for computing an amount of movement of the image processing window based on values of vehicle velocity and steering angle.
Claim 5
Dependent Claim
49 words
The system according to claim 3, wherein said arithmetic means moves the image processing window farther ahead of the vehicle or closer to the vehicle along the road based on a change in vehicle velocity, and leftward and rightward across the road based on a change in steering angle.
Claim 6
Dependent Claim
49 words
The system according to claim 1, wherein said image processing means comprises: means for setting a plurality of reference image processing windows, and arithmetic means for computing an amount of movement of each of the plurality of image processing windows based on values of vehicle velocity and steering angle.
