<P>PROBLEM TO BE SOLVED: To automatically calculate a coefficient for separating visible light and infrared light. <P>SOLUTION: A coefficient calculation device for an image sensor comprises: an amplitude value acquisition part for acquiring from an image sensor including a first element outputting a first signal by photoelectric conversion of received visible light and infrared light and a second element outputting a second signal by photoelectric conversion of received infrared light, amplitude values of the first and second signals; a signal separation part for extracting a visible light component included in the first signal by subtracting the amplitude value obtained by multiplying the amplitude value of the second signal output from the second element by a first coefficient, from the amplitude value of the first signal output from the first element; and a coefficient calculation part for calculating the first coefficient based on the amplitude values of the first and second signals. <P>COPYRIGHT: (C)2012,JPO&INPIT |
