Abstract
An electronic control apparatus including a time synchronizing unit configured to collect GrandMaster (GM) clock time information and to perform time synchronization based on the GM clock time information, a comparison unit configured to receive video frames captured from a camera among multi-channel cameras, to compare time information of the video frames with the GM clock time information, and to thereby generate and output delay time information for the video frames to be delayed compared to the GM clock time information; and an image synchronizing unit configured to perform image synchronization between the multi-channel cameras by adjusting an image output time of the camera based on the delay time information.
