An imaging system for a vehicle includes an imaging device having a field of view exteriorly and forward of the vehicle in its direction of travel, and an image processor operable to process the captured images in accordance with an algorithm. The algorithm comprises a sign recognition routine and a character recognition routine. The image processor processes the image data captured by the imaging device to detect signs in the field of view of the imaging device and applies the sign recognition routine to determine a sign type of the detected sign. The image processor is operable to apply the character recognition routine to the image data to determine information on the detected sign. The image processor applies the character recognition routine to the captured images in response to an output of the sign recognition routine being indicative of the detected sign being a sign type of interest.
What is claimed is: 1. An imaging system for a vehicle comprising: an imaging device having a field of view exteriorly and forward of the vehicle in its direction of travel, said imaging device being operable to capture images representative of the exterior scene in the forward field of view; an im
What is claimed is: 1. An imaging system for a vehicle comprising: an imaging device having a field of view exteriorly and forward of the vehicle in its direction of travel, said imaging device being operable to capture images representative of the exterior scene in the forward field of view; an image processor operable to process the captured images in accordance with an algorithm, said algorithm comprising a sign recognition routine and a character recognition routine, said image processor processing the captured images to detect signs in the field of view of said imaging device, said image processor (a) applying said sign recognition routine to the captured images to determine a sign type of the detected sign and generating a sign recognition output, and (b) responsive to said sign recognition output being indicative of the detected sign being a sign type of interest, then applying said character recognition routine to the captured images to determine information on the detected sign; and wherein an output generated by said image processor triggers at least one alert to a driver of the vehicle, said at least one alert comprising at least one of a visible alert, an audible alert and a tactile alert, wherein said alert is displayed on a display device that is viewable by the driver of the vehicle, wherein said display device comprises a laser display device, wherein said laser display device comprises at least one laser emitting device that is rastered across a display area to display information at a display viewing area for viewing by the driver of the vehicle, and wherein said laser emitting device is rastered across a reflector that reflects the laser beams onto the display viewing area for viewing by the driver of the vehicle. 2. The imaging system of claim 1, wherein said algorithm provides reduced processing of the captured images in response to said sign recognition output being indicative of the sign type being other than a sign type of interest. 3. The imaging system of claim 1, wherein said character recognition routine determines what the characters on the face of the sign represent. 4. The imaging system of claim 1, wherein said at least one alert is indicative of at least one of the vehicle speed, a posted speed limit and a difference between the vehicle speed and the posted speed limit. 5. The imaging system of claim 1, wherein said imaging system is responsive to a vehicle speed input indicative of the speed that the vehicle is traveling, said alert conveying information to the driver of the vehicle in response to said output of said image processor and said vehicle speed input. 6. The imaging system of claim 5, wherein said imaging system generates said alert to alert the driver of a condition where the vehicle speed is a threshold amount above or below a speed limit determined by said image processor. 7. The imaging system of claim 6, wherein said alert comprises a visible alert that at least displays the vehicle speed and the posted speed limit. 8. The imaging system of claim 1, wherein said reflector comprises an adjustable reflector, said adjustable reflector being controllable to adjust the information reflected onto the display viewing area. 9. The imaging system of claim 1, wherein said laser emitting device and said reflector are positioned within a casing of an interior rearview mirror assembly and said display viewing area is defined at a reflective element of said interior rearview mirror assembly. 10. The imaging system of claim 9, wherein said reflective element of said interior rearview mirror assembly comprises a transflective reflective element.
