  • USP7847705

  • USP8022836

  • USP8237580

  • USP8264367

 

Overview of the patents

In conventional in-vehicle image display apparatuses (e.g., car navigation systems), it is not possible to display the image of the current view outside the vehicle during driving of the vehicle.  Therefore, when the driver’s visibility becomes poor due to weather or when the driver’s eyesight is temporarily weakened, the driver may not be able to know exactly the circumstances around the vehicle.

This group of patents relates to a technology in which the circumstances around the vehicle during driving is accurately reproduced in real time by an image and such an image is displayed on the window.

 

We are looking for a company that will consider putting these patents into practical use.

 

Points of the patents

  • The display easily viewable by the driver can be achieved by highlighting a moving object, for example.
     

  • Even the circumstances far away from the vehicle can be  grasped because such circumstances can be displayed on the near window.
     

  • Occurrence of accidents due to delay in risk aversion can be prevented.
