1. A display system comprising:
- a processor to control one or more processor-executable units;
a location information provider unit to provide location information of a face or eyes of a user generated based on information received from a plurality of cameras;
a posture information provider unit to provide posture information of the display system generated based on information received from a plurality of sensors; and
a final location determining unit to determine a final location of the user with respect to the display system based on the location information of the face or the eyes of the user and the posture information of the display system,wherein the final location determining unit searches for a location of the face or the eyes of the user within a predetermined range within an image from the plurality of cameras,wherein the predetermined range is determined based on X and Y coordinates of the user on the image with respect to the display system,wherein each sensor type differs among the plurality of sensors, andwherein the final location determining unit comprises;
a relative location calculator to calculate the X and Y coordinates based on the posture information in response to a posture of the display system being changed.
