DIGITAL VIEWING SYSTEM FOR VEHICLES
The present invention refers to a digital viewing system for vehicles, suitable to be installed on a vehicle for helping a driver when driving under scarce visibility conditions, for example caused by fog, rain or snow. In particular, the present invention refers to a digital viewing system comprising an image acquisition device, for example a video-camera, adapted to be installed inside and/or outside a motor vehicle.
Viewing systems are known, which are suitable to be installed on a vehicle for helping a driver when driving under scarce visibility conditions.
These viewing systems, however, are not satisfactory and have the problem of providing for the use of video-cameras of the infrared (IR) type or of laser devices to detect, for example, the presence of fog.
The Applicant has observed that, by using an image acquisition device of a known type, for example a digital video-camera equipped with backlit CMOS sensor and balanced image stabilizer, under scarce visibility conditions on a moving vehicle, a clear viewing is surprisingly obtained even with the presence of fog, rain or snow.
Object of the present invention is providing a digital viewing system for vehicles, adapted to help a driver when driving a vehicle under scarce visibility conditions, for example caused by fog, rain or snow.
A further object of the present invention is solving the above prior art problems by providing a digital viewing system suitable to be installed on a vehicle, in particular on a motor vehicle, which uses in particular an image acquisition device, for example a video-camera of a known type, for helping a driver when driving under scarce visibility conditions, for example in case of fog.
