A light exposure control device and method that allows three excitation signals to be generated by a counter and sent to a CCD module after the CCD module has been exposed to an image. Inside the CCD module, a red photodetector, a green photodetector and a blue photodetector can be separately triggered to capture the necessary image signals. The excitation signals sent to each CCD photodetector are independent from each other. Furthermore, each CCD photodetector reacts only to a specific excitation signal. Therefore, constraints caused by unrelated excitation signals are avoided, and so exposure time can increase considerably.
