An imaging system for a vehicle is provided for distinguishing between tail lights of another vehicle and a flashing red stop light. The system includes an imager configured to image a forward external scene and to generate image data corresponding to the acquired images; and a processor configured to receive and analyze the image data to identify red light sources and to further analyze each red light source to determine if the red light source is detected for a predetermined time period. If the red light source is not detected within a predetermined time period after it is detected, the processor determines that the red light source is a flashing red stop light. Otherwise, if the red light source is detected for a predetermined time period, the processor determines that the red light source may be a tail light of another vehicle.

Vehicle imaging system and method for distinguishing between vehicle tail lights and flashing red stop lights

An imaging system for a vehicle is disclosed having an image sensor positioned in the vehicle for capturing images through a windscreen of the vehicle and for generating image data corresponding to the captured images, and a processor coupled to the image sensor for receiving and analyzing the image data and detecting vehicle light sources in the captured images. The processor: detects a predetermined number of vehicle light sources; averages color values of each detected vehicle light source; determines differences between the averaged color values and target color values; and stores the differences as color compensation values. A vehicle equipment control system is further disclosed having the imaging system above, wherein the processor compensates color values of subsequently detected vehicle light sources and generates a control signal that is used to control the vehicle equipment in response to the detection of color compensated vehicle light sources in the captured images.

Imaging system including dynamic compensation for color attenuation for vehicle windscreens

An imaging system and method is provided that generates image data. A processor is configured to process the image data and to generate a signal in response to analysis of the image data and a selected mode of operation. The processor selects either a village mode or a non-village mode as a mode of operation depending on whether at least one characteristic in the image data meets village detect conditions. The processor monitors an ambient light level over a period of time and modifies the village detect conditions when the ambient light level reaches a threshold that indicates that the driver's eyes have adapted to a bright ambient light level.

Imaging system and method for detecting a bright city condition

An exterior light control system for controlling exterior lights of a controlled vehicle is provided, which includes an imager configured to image a scene external and forward of the controlled vehicle and to generate image data corresponding to the acquired images. A controller is configured to receive and analyze the image data and generate a control signal for controlling the exterior lights of the controlled vehicle. The controller is further configured to receive temperature information relating to an operational temperature of the imager, wherein when the controller determines that the operational temperature of the imager is below a temperature threshold, the control signal includes an indication that the imager is blocked.

System and method for detecting a blocked imager

A system for controlling equipment of a vehicle is provided. The system is configured to image a scene external and forward of the controlled vehicle and to generate image data corresponding to acquired images including a controller for receiving and analyzing the image data and for generating a control signal in response to analysis of the image data and in response to a selected mode of operation. The controller analyzes the data in order to detect at least one characteristic in the image data and selects a mode of operation from at least one of the following modes of operation: the controller selects a dark village mode if at least one characteristic reaches a first threshold, a bright village mode if at least one characteristic reaches a second threshold, and a non-village mode if the controller is not operating in either the dark village mode or the bright village mode.

System and method for controlling vehicle equipment responsive to a multi-stage village detection

A system is provided for controlling equipment of a controlled vehicle, including: an imaging system including an image sensor configured to acquire images of a scene external of the controlled vehicle and to generate image data corresponding to the acquired images; and a controller in communication with the imaging system. The controller is configured to receive and analyze the image data, to generate a control signal that is used to control the equipment, and to automatically aim the image sensor. The controller may analyze the image data to determine a stability state for the aim of the image sensor. The control signal may include an aim stability indication.
