Presentation, design, and application of a real-time demosaicing generic model based on a multiple channel CMOS image sampling system

In this paper, a real-time demosaicing generic model is presented, which is concise, easy to implement, resources-saving and robust. With the model, multiple displaying demosaicing subsystems can be realized in terms of a Bayer pattern color filter array. A LCD displaying subsystem is designed by FPGA, and the waveform simulated is presented. The monitoring results of a real scene are captured and illustrated. To prove the LCD monitoring results, the application background of the LCD subsystem is given, which is a multiple channel CMOS image sampling system. The three images exposed synchronously in the background system and the pictures stored are shown, one of which is identical to the scene monitored by the LCD subsystem. Finally, to demonstrate the generality of the model, the test results of a CRT demosaicing displaying subsystem designed with the model in the background system are given.
