Imaging system for vehicle

An imaging system suitable for use with a vehicle based global positioning system, the vehicle based global positioning system being operable to determine a vehicle position in response to a satellite communication and to provide position data of the vehicle position, said imaging system comprising:

• an imaging sensor operable to capture an image of a scene exteriorly of the vehicle, said imaging sensor being positioned at one of an interior portion of the vehicle and an exterior portion of the vehicle;
• and
• a control operable to process said image and to provide a record of vehicle movement via processing of said image, said control being operable to receive the position data from the vehicle based global positioning system, said control being operable to determine a current vehicle location via said record of vehicle movement when the satellite communication to the vehicle based global positioning system is interrupted, said imaging sensor comprising a pixelated imaging array sensor comprising a plurality of photosensing pixels, wherein said control is operable to scale image data from at least one frame of said images captured by said imaging sensor.

Am imaging system suitable for use with a vehicle based magnetic compass system, the vehicle based magnetic compass system having at least one magnetoresponsive sensor operable to determine a vehicle heading of the vehicle, said imaging system comprising:

• an imaging sensor operable to capture images of a scene exteriorly or the vehicle, said imaging sensor being positioned at one of an interior portion of the vehicle and an exterior portion of the vehicle;
• and
• a control operable to process said images, said control at least occasionally calibrating the at least one magnetoresponsive sensor of the vehicle based magnetic compass system in response to said processing of said images and in response to an output of the at least one magnetoresponsive sensor of the vehicle based magnetic compass system.
