A method for dating images obtained by at least one camera equipping a vehicle includes acquiring a reference signal including time information and generating a modulated signal in response to the reference signal. The modulated signal has at least one retiming pulse with a retiming period which that is different from a base period of the modulated signal. The method further includes, for each camera acquiring images at a frequency depending on the frequency of the modulated signal, each image being associated with a timestamp provided by the camera, and determining the time difference between the timestamps of two successive images of the camera. If the time difference determined between said timestamps is different from the base period of the modulated signal, the method assigns a reference date to said images depending on the time information of the reference signal.

The controller controls the timing generator in such a way that a period over which the first image sensor exposes lines within the duplicate region in the first image data coincides with a period over which the second image sensor exposes lines within the duplicate region in the second image data.
