Light Sensitive System and Method for Attenuating the Effect of Ambient Light

摘要

There is provided a light-sensitive system responsive to light supplied by the system and less responsive to other light. The system includes a light source operable to supply time-modulated illumination, and a light sensor having greater response to the time-modulated illumination than to light from sources not so modulated. The invention may be embodied as a camera sensitive to supplied light and relatively insensitive to ambient light, and is useful in providing images for automated image interpretation. A method for photographing an object is also provided.
