Vision Sensor DENSO’s vision sensor, installed next to a vehicle’s inside rear view mirror, detects lane markers on the road ahead.

How it works:

• A camera on the vision sensor photographs lane markers ahead.
  
• The vision sensor calculates positions and shapes of the lane markers photographed (lane marker recognition process), and sends the information to the steering assist ECU.
  
• The vision sensor automatically adjusts the exposure of the camera to perform the lane marker recognition process more easily and accurately.

Benefits and Features

• Small size
  
  • Adopting a CMOS image sensor for the camera results in a simple image sensor control circuit.
    
  • A microcomputer performs the photographing process as well as the lane marker recognition process, simplifying processing circuits.
    
• High resolution
  
  • The CMOS image sensor has approximately 300,000 pixels (640 pixels X 480 pixels).
