A dimming system 12 for a vehicle mirror comprises: image capturing means 20 arranged to acquire a captured image that corresponds to a reflected image of a scene appearing in the mirror 14; processing means 22 arranged to analyse the captured image and to determine an image mask (108, figure 6); and masking means arranged to implement the image mask determined by the processing means, wherein the image mask is operable to reduce the brightness of one or more selected zones (112-118) in the reflected image in proportion to the brightness of a respective one or more zones in the captured image. In a further embodiment the dimming system may operate on a vehicle display, such as an LED, LCD or OLED screen which is used to display an image outside of the vehicle. The system is intended to dim only sections of the mirror or display which have areas of glare above a threshold value, thus leaving the remaining areas of the mirror or display undimmed. |
