Our dynamic brightness revision does not give a feeling of strangeness when viewing the back of the car monitor, because the quality correction is done in real time for the captured image. (The time required for real-time, line number 10)
External frame memory is not required, can be achieved in only 10 lines memory and a circuit, so it’s a very compact.

Dynamic brightness revision is a technique for performing image correction can be recognized. For example, the following captured image due to lack of image representation by the high brightness and low brightness.

-Scene that the human eye cannot recognize.
-Scene that the dark shadow causes outlines cannot be recognized.
-Scene that the fog and clouds have spread, and background buildings have disappeared.
