  4. CONSTRUCTION


    1. Rear Television Camera Assembly


      1. The rear television camera assembly consists of a wide-angle lens and a Complementary Metal Oxide Semiconductor (CMOS).

      2. An image captured by the rear television camera assembly lens is converted into electrical signals according to the light intensity by using the CMOS image element, and the signals are then output to the radio and display receiver assembly.

      3. The image output from the rear television camera assembly is reversed to much the rear view seen from the inner rear view mirror assembly. Therefore, the rear view actually seen is displayed on the screen in the horizontal reverse.
