Abstract

A driver customizable blind spot display method and apparatus are provided. The method of displaying blind spots of a vehicle via a screen mounted within a vehicle includes receiving information regarding positions of the driver'"'"'s eyes from a driver state monitoring system and receiving current mirror setting information on a per in-vehicle mirror basis from a mirror drive unit. Blind spots and viewable spots are then calculated using the information regarding positions of the driver'"'"'s eyes and the current mirror setting information. Particularly, the position of the driver'"'"'s eyes is used to determine optimum mirror setting information. A mirror plane angle is then adjusted based on the optimum mirror setting information. A current blind spot coverage screen is then output to display the calculated blind spots and viewable spots.
