A controller 300 for controlling cleaning of a vehicle camera 100. The controller 300 is configured to receive an image signal from a vehicle camera 100, the image signal being indicative of an image captured by the vehicle camera 100, generate a feature parameter based on the image, compare the feature parameter to a reference parameter to obtain a parameter difference, and, if the parameter difference is greater than a threshold value, to output a cleaning signal from the controller 300 to cause the vehicle camera 100 to be cleaned. The feature parameter may be a light level value, which may be an average light level in the image. The feature parameter may be a fixed vehicle feature such as an object edge and the controller 300 is configured to determine a sharpness parameter associated with the object edge. Determination of the reference parameter may involve capturing multiple images, the first image and second image captured at different times.
