1. An aircraft cabin ambient light control system for monitoring and controlling the light intensity level within an aircraft cabin, the system comprising:
a dimmable window having an electrically controllable opacity level;
a central cabin controller electrically coupled to the dimmable window;
and an ambient light controller electrically coupled to the central cabin controller, wherein the ambient light controller comprises a processing unit electrically coupled to a plurality of cameras and a communication interface, and wherein:
the plurality of cameras continuously capture video within the aircraft cabin and transfer the video stream to the processing unit;
the processing unit analyzes the video and identifies a light intensity level within the aircraft cabin;
the communication interface sends data to the electrically coupled central cabin controller;
the central cabin controller sends a command signal to the dimmable window to control the opacity level of the dimmable window;
wherein the processing unit comprises:
a video capture module configured to capture the video from the plurality of cameras;
a video analyzer module configured to process the video from the plurality of cameras to remedy low light and low-resolution videos;
a light intensity level identifier module configured to analyze the processed video from the plurality of cameras to identify the light intensity level within the aircraft cabin; and
a window locator module configured to analyze features extracted from the processed video to identify dimmable windows which require an opacity level adjustment.
