Device and method of monitoring surroundings of a vehicle

A device for monitoring surroundings of a vehicle, comprising:

• a first imaging device for imaging outside of the vehicle in a first imaging area at a predetermined cycle period;
• a second imaging device for imaging outside of the vehicle in a second imaging area at a predetermined cycle period, said second imaging area and the first imaging area overlapping each other at least partially;
• and
• an information generating device for generating predetermined information in which a lag between imaging timing of the first imaging device and imaging timing of the second imaging device is corrected based on images of both the first and the second imaging devices.

A method of monitoring surroundings of a vehicle, comprising:

• a step of imaging outside of the vehicle at a first timing using a first imaging means;
• a step of imaging outside of the vehicle at a second timing which is earlier or later than the first timing using a second imaging means;
• a corrected image generating step of correcting an image of the first imaging means based on a lag between the first timing and the second timing;
• and
• an information generating step of generating predetermined information using the corrected image obtained by the corrected image generating step and an image of the second imaging means.
