Abstract: A light-emitting diode (LED) light source control method is disclosed. The light-emitting diode light source control method is used for controlling a composite and a single color LED light source. The composite color LED light source can provide two of the three original red, green and blue color lights and the single color LED light source provides the third original color. The composite and the single color LED light sources provide illuminations sequentially so that the light sources need not to be turned on continually and the data generated by the composite and the single color lights on the red, green and blue channels of image sensors can be processed sequentially.
