A camera system with lighting strength control includes: an image sensor for capturing images of a scene a light source for illumination of the scene and a signal generator, in communication with the image sensor and the light source, for generation of (a) a first signal for controlling image capture by the image sensor and (b) a second signal for controlling a duty cycle of the light source. A method for controlling the lighting strength of a camera system, which includes an image sensor, an associated light source, and an associated signal generator, includes: (a) generating, using the signal generator, a first signal that controls image capture by the image sensor, and (b) generating, using the signal generator, a second signal that controls a duty cycle of the light source.一種具有光強度控制之攝像系統包含一影像感測器、一光源以及一訊號產生器。影像感測器用以擷取一場景之影像。光源用以照射場景。訊號產生器係耦接於影像感測器及光源,用以產生(a)一第一訊號來控制影像感測器之影像擷取,以及(b)一第二訊號來控制光源之一工作週期。一種用以控制攝像系統之光強度之方法,攝像系統包含一影像感測器、一相關聯之光源與一相關聯之訊號產生器。上述方法包含:(a)藉由使用訊號產生器而產生一第一訊號以控制影像感測器之影像擷取;以及(b)藉由使用訊號產生器而產生一第二訊號以控制光源之一工作週期。
