Abstract

A vision system for a vehicle includes an imaging device, a camera controller, a display device and a display controller. The camera controller and the display controller share a common processor. The vision system is operable to adjust a displayed image responsive to a signal from an auxiliary sensing system. The vision system, responsive to object detection by a sensor, is operable to (a) provide enhanced imaging of the detected object, (b) provide enhanced processing of at least a portion of captured image that corresponds to the region of the exterior scene at which an object is detected, (c) adjust the display device to enhance displayed images of a detected object, and/or (d) adjust the display device to enhance display of at least a portion of a captured image that corresponds to the region of the exterior scene at which the object is detected by the sensor.

Claims

1. A vision system for a vehicle, said vision system comprising:

an imaging device having a field of view exterior the vehicle;

a camera controller;

a display device having a display element, said display device operable to display information for viewing by a driver of the vehicle;

a display controller;

wherein said camera controller and said display controller share a common processor;

wherein said vision system is operable to adjust an image displayed by said display device in response to a signal from an auxiliary sensing system of the vehicle;

a sensor operable to detect an object exterior the vehicle; and

wherein said vision system, responsive to said object detection by said sensor, is operable to at least one of (a) provide enhanced imaging of the detected object by said imaging device, (b) provide enhanced processing of at least a portion of an image captured by said imaging device that corresponds to the region of the exterior scene at which an object is detected by said sensor, (c) adjust said display device to enhance displayed images of an object detected by said sensor and (d) adjust said display device to enhance display of at least a portion of an image captured by said imaging device that corresponds to the region of the exterior scene at which the object is detected by said sensor.

2. The vision system of claim 1, wherein said sensor comprises at least one of an ultrasonic sensor, a radar device, a sonar device, a laser sensing device, a lidar device and a laser scanning device.

3. The vision system of claim 1, wherein said imaging device comprises a video encoder.

4. The vision system of claim 1, wherein said display device is associated with an interior rearview mirror assembly of the vehicle.

5. The vision system of claim 1, wherein said display device is associated with an accessory module of the vehicle.
