Abstract
A method for detecting an incident on a traffic lane uses a video camera having a target constituting an optoelectronic converter of a real optical image, the target being monitored by a programmable processing member and the incident detection process being designed to be carried out by activating the programmable processing member only when the real landscape image focused on the target is stationary. The inventive method includes detecting the beginning of displacement of the real image of the landscape relative to the target, in deactivating the programmable processing member right at the beginning of the displacement of the real image of the landscape relative to the target, and reactivating the programmable processing member at the end of the displacement of the real image of the landscape relative to the target to carry out the incident detection process.
