A method for controlling the operation of the windscreen wiper system monitors light reflected from a portion of a windscreen and creates an image of the moisture condition of the windscreen based on the reflected light. The image is analyzed to determine the configuration of light intensities in predetermined zones. From the light intensity configuration, the moisture condition of the windscreen is determined. The sensed moisture condition parameters are compared to a threshold array and a signal based upon this comparison is communicated the wiper, defogger, or headlight control system.
