Abstract
At least one image of a moving object is acquired using an image acquisition device equipped with an automatic focussing system. A distance between the object and the device when the effective acquisition of the image occurs is estimated based on the estimated speed and on the period of time separating a time of actuation triggering the process for acquiring the at least one image from the time of acquisition of the said effective acquisition, and the taking into account of the said distance by the automatic focussing system.
