PROBLEM TO BE SOLVED: To provide a device, system and method for determining a vehicle color, capable of determining a color of a vehicle at low cost and with sufficient accuracy.SOLUTION: A plate recognition unit 14 recognizes a number plate. A plate position calculation unit 15 calculates a motion vector (xm, ym) of a plate position on the basis of a coordinate (xp, yp) of a plate position on a pick up image for a plate at different imaging time. A vehicle body color decision area specification part 17 calculates a coordinate (xs, ys) of the plate position on a pick up image for color decision at imaging time t+n after elapse of prescribed time from the imaging time t+1 on the basis of the coordinate (xp, yp) of the plate position, moving distance (for example, ym) of the plate position, etc., and specifies a vehicle body color decision area on the basis of the calculated coordinate (xs, ys) of the plate position. A vehicle body color decision part 18 determines the color of the vehicle on the basis of a pixel value of the vehicle body color decision area.
