Abstract
An image taking unit takes an image by exposing three color light receivers and an invisible light receiver. The three color light receivers are sensitive to light in an invisible region emitted by an invisible light projector, and concurrently sensitive to the respective three primary colors of light. The invisible light receiver is sensitive to the light in the invisible region emitted by the invisible light projector. A marker pulse generator generates an exposure timing pulse for the image taking unit, and an emission timing pulse for the invisible light projector on the basis of a reference signal. A color image creator creates a color image from outputs from the respective color light receivers. A synchronous detection processor creates a detection image by performing a synchronous detection process on the outputs from the color light receivers and the invisible light receiver by use of the reference signal.
