They say necessity is the best inventor. One such invention that came into existence due to a dire necessity is the reversing camera. This is a special video camera that was specifically produced for the purpose of providing drives with a better rear view in order to aid the backing up process.
Reversing cameras go by many different names in the market. They are popularly known as rear view cameras and backup cameras. There are a number of reasons that led to the development of the backup camera. Primarily they function to help the driver. They make it easy to watch out for obstacles that may not be visible through the conventional rear view mirror. They also help to avoid bumping into other cars while parking your car in a tight spots.
Furthermore statistics go to show that young pedestrians face a grave threat from backing up cars across the world. This is especially true with regards to little children. Since their height is small they are often not visible to the backing up driver. As a result many children are injured and some even lose their lives in backing up accidents. The backup camera comes to the deliverance of all those young pedestrians that stand in danger of being run over by a reversing car.
The architecture of the reversing camera
The reversing camera has a strikingly different design from other conventional cameras. Basically these cameras flip the image horizontally so that the display you get on your screen is a mirror image of what lies behind you. It was essential to incorporate this function into backup cameras because the camera faces in exactly the opposite direction of the driver. If this technology was not incorporated then the driver could get really confused as his right would be the camera’s right and vice versa. With the mirror image the balance is retained and the orientation is ideal for the driver to take advantage of.
Initially backup cameras were used on tow trucks and huge vehicles that made it impossible for the driver to get a good view of the rear. In recent years however the technology of backup cameras has evolved and they are increasingly being incorporated into conventional cars.
Since LCD display screens, GPS and DVD players have become a popular feature in cars, it made sense to develop a backup camera that could aid the reversing process in normal cars as well. Some of the latest cars already come with built in backup cameras as an added feature. Interested individuals can even purchase these cameras from car accessory shops.
In order to provide a comprehensive view of the rear backup cameras feature a wide angle lens and in some cases a fisheye lens. The use of such a lens hinders the camera’s ability to pick up distant images but it gives the driver an uninterrupted horizontal view of the rare. Since the camera is meant to watch out for close obstructions it does not matter whether the camera can pick up distant images or not. The camera is fixed in a downward pointing position in order to give a view of obstacles on the surface of the floor as well as corners and cars.
