Abstract
The present invention relates to a method and apparatus for controlling synchronization of camera shutters in an in-vehicle Ethernet communication network. A method for controlling synchronization of a camera shutter by a camera controller cooperating with a grandmaster through Ethernet communication may include performing a time synchronization procedure with the grandmaster, reducing a preset pulses per second (PPS) down counter if the time synchronization procedure is successfully completed, and operating the camera shutter when the PPS down counter reaches 0. Accordingly, the present invention may provide accurate image frames of a desired time through synchronization of shutters of cameras connected to an in-vehicle Ethernet network.
