Abstract
A detection system comprises a light source configured to illuminate an object, an image sensor configured to receive light reflected from the object, and a processor. The image sensor generates a first picture when the light source is turned on. The image sensor generates a second picture when the light source is turned off. The processor is configured to subtract the second picture from the first picture for determining an object image produced by the object.
