In addition, the configuration and structure of the facility is simple, it is possible to lower the production cost of the vehicle.

The images obtained from the image sensors installed at both sides of the vehicle are transmitted to the projector {PROJECTOR}, and the image transmitted to the projector {PROJECTOR} is optically converted to produce a wide-angle image. It is projected onto the sunscreen area on the top of the windshield to provide the driver with image information on both sides and behind. In the case of an image projector having a single image output lens, a long distance between the image projector and the screen is required to realize a wide viewing angle image. An image projector having multiple output lenses for near-field wide viewing angle image projection used in both side and rear image realization systems of a vehicle using the above-mentioned near-field projector and windshield is a triangle at the end of the projector having a single image output lens. Alternatively, a triangular reflective mirror is installed to divide the output image into two, and the two divided images are implemented using a convex mirror to implement a wide-angle image, and the image divided by the wide viewing angle is projected by the image projector. It is designed to enable image projection using an image projector even in a narrow space such as a vehicle by reducing the distance between the screen and the screen. Front of vehicle compared to footage By providing a wider image on both sides and rear with the front image, the driver provides a wide-angle image that conventional side mirrors or room mirrors cannot provide, and ultimately replaces the conventional camera or alarm for rear detection.

By providing a screen image of the opaque area of the sun protection foil on the upper part of the windshield of the vehicle, the driver can observe the images of both sides and the rear as a single image. By observing the conventional sunscreen on the windshield of the vehicle, it is possible to grasp the situation around the vehicle. In addition, in the case of the mirror located in the rear end of the conventional blind spots due to its size and shape, but the vehicle image information transmission system having the image sensor and the projector {PROJECTOR} is an image sensor installed on both sides of the vehicle and the ceiling or dashboard of the vehicle By using the projector attached to the projector, you can maximize the driver's view. In addition, the driver of the vehicle can use the above-mentioned near-field projector and the windshield to realize the situation around the vehicle, which cannot be seen by using a conventional side mirror, by using the image realization system on both sides and the rear of the vehicle. This can be seen through the image of the side and rear of the vehicle projected onto the area. In addition, in the case of the conventional rear surveillance camera, the vehicle image information transmission system having an image sensor and a projector {PROJECTOR}, which is fixed to the vehicle and provides only the rear image fixed to the vehicle, has a conventional side mirror in the image sensors installed on both sides of the vehicle. Combining the structure used to change the direction of the image on the windshield screen of the vehicle can be adjusted according to the convenience of the driver.
