Abstract
A vehicle camera system for obtaining picture data of a runaway vehicle is provided in a toll road system. A vehicle passing a tollgate (4) is picked up by a camera (6). As a license plate of a vehicle is detected, picture data are cyclically and subsequently stored in a pluarlity of fram memories (20). When the vehicle dishonestly leaves without paying a toll, a tollbooth attendant (m) depresses a push button (3) to generate an instruction signal so that one or a plurality of picture data just before the timing of such depression can be read out from the frame memory (20) to be transmitted to a central unit for separate storage. The instruction signal may also be generated automatically based on detection of the vehicle.
