2. Description of the Related Art
A technique to visualize or a technique to detect a pedestrian and an obstacle (hereinafter may be referred to as an “object”) is important to improve the safety of automobiles. An image pickup system using a range gate camera is known as a representative instance. The range gate camera is a camera that is designed to have exposure (the gate is opened) only for an extremely short specific time. It is possible to pick up an image of only an object at a predetermined distance by a combination of a range gate camera and pulsed irradiation light. With a range gate camera, an adverse effect of a fog which is present in front of an object may be eliminated. A range gate camera also functions as a time of flight (TOF) image pickup system by successively changing gate opening timing. A range gate camera is disclosed in, for instance, in Mitsubishi Heavy Industries Technical Review Vol. 42, No. 5, P. 212 (2005-12).
