Abstract
The invention discloses an image display control system and an image display control method thereof. A projection device receives a blue-light signal, a green-light signal, a red-light signal and an infrared signal. The image display control system controls a light source device to emit blue light according to the blue-light signal, and also controls the light source device to emit infrared light according to the infrared signal, but not to emit green light or red light. A first modulation unit modulates the blue light according to the blue-light signal to emit blue-light image light, during which a second modulation unit modulates the infrared light according to the infrared signal to emit infrared image light. The emission and modulation of green and red light follow the same principle. The image display control system can not only use the visible light and the infrared light together to simultaneously display an visible light image and an infrared light image, but also improves the utilization ratio of the modulation units.
