Abstract
In a method for debouncing light-characteristic changes (e.g., streetlights, headlights of other vehicles), which are ascertained from image data of a camera for a vehicle, light-characteristic changes are identified in a continuous image sequence and a distance in time is determined between the light-characteristic changes. A spatial distance between the light-characteristic changes is determined with reference to the speed of the vehicle and from the distance in time between the light-characteristic changes. The debouncing is based on the spatial distance.

14. A method for debouncing at least two light-characteristic changes ascertained from image data of at least one camera for a host vehicle, comprising:
-
identifying the at least two light-characteristic changes in a continuous image sequence of the at least one camera; determining a separation in time between the at least two light-characteristic changes; determining a spatial distance between the at least two light-characteristic changes based on the separation in time between the at least two light-characteristic changes, with reference to the speed of the vehicle; and debouncing the at least two light-characteristic changes based on the spatial distance. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A device for debouncing at least two light-characteristic changes, the device located in a host vehicle, comprising:
-
an interface unit for receiving image data of at least one camera for a vehicle; and a detection unit for detecting light-characteristic changes, wherein the detection unit (i) identifies at least two light-characteristic changes in an image sequence of the image data received at the interface unit, and (ii) determines a spatial distance between the at least two light-characteristic changes based on separation in time between the at least two light-characteristic changes, with reference to the speed of the vehicle host; wherein debouncing of the at least two light-characteristic changes is based on the spatial distance.
