5. The stereoscopic cluster of claim 2 , wherein the processor is configured to determine whether a current time is nighttime

when the at least two pairs of left and right eyes are detected and the second user other than the first user is absent.

6. The stereoscopic cluster of claim 5 , wherein the processor is configured to:

when the at least two pairs of left and right eyes are detected, the second user other than the first user is absent, and the current time is the nighttime,

distinguish the true pair of left and right eyes of the first user based on a dimension of each of the at least two pairs of left and right eyes, and based on a distance between each of the at least two pairs of left and right eyes and the stereoscopic cluster.

7. The stereoscopic cluster of claim 5 , wherein the processor is configured to determine a current state as an abnormal state

when the at least two pairs of left and right eyes are detected, the second user other than the first user is absent, and the current time is daytime.

8. The stereoscopic cluster of claim 7 , wherein the processor is configured to control the display to provide a two-dimensional (2D) screen thereon

when the current state is determined as the abnormal state.

9. The stereoscopic cluster of claim 8 , wherein the processor is configured to:

when determined that the abnormal state returns to a normal state while the 2D screen is being presented, provide a pop-up on the display such that the first user selects whether to change the 2D screen to the stereoscopic screen.

10. The stereoscopic cluster of claim 5 , wherein the processor is configured to

determine whether the current time is the nighttime based on at least one of information received from an auto-light sensor or information received from a navigation device.

11. The stereoscopic cluster of claim 1 , wherein the processor is configured to:

detect a face zone of the first user;

detect features in the detected face zone; and

track coordinates of left-right eyes among the features.

12. The stereoscopic cluster of claim 1 , wherein the display includes:

an image panel including a right-eye image pixel for providing a right image for a right-eye, and a left-eye image pixel for providing a left image for a left-eye; and

a barrier disposed on a front face of the image panel, wherein the barrier is controlled by the processor.

13. The stereoscopic cluster of claim 12 , wherein the processor is configured to control the barrier based on a position of the true pair of left and right eyes of the first user.

14. A system comprising:

a passenger detection device configured to detect presence or absence of a passenger in a vehicle; and

a stereoscopic cluster for the vehicle, wherein the cluster is configured to:

detect at least one pair of left and right eyes from acquired image data;

when at least two pairs of left and right eyes including a false pair of left and right eyes of a first user reflected on a window of the vehicle are detected, distinguish a true pair of left and right eyes of the first user among the at least two pairs of left and right eyes; and

provide a stereoscopic screen based on the distinguished true pair of left and right eyes of the first user.

15. A method for providing a stereoscopic screen, the method comprising:

detecting, by a processor, at least one pair of left and right eyes from acquired image data;

when at least two pairs of left and right eyes including a false pair of left and right eyes of a first user reflected on a window of the vehicle are detected, distinguishing, by the processor, a true pair of left and right eyes of the first user among the at least two pairs of left and right eyes; and

providing, by the processor, a stereoscopic screen based on the distinguished true pair of left and right eyes of the first user.

16. The method of claim 15 , wherein distinguishing the true pair of left and right eyes of the first user includes:

when a number of the detected pairs of left and right eyes in the vehicle is at least three, determining presence or absence of a second user other than the first user in the vehicle; and

when the second user is present, distinguishing the true pair of left and right eyes of the first user based on a dimension of each of the at least three pairs of left and right eyes, and based on a distance between each of the at least three pairs of left and right eyes and a stereoscopic cluster.

17. The method of claim 15 , wherein distinguishing the true pair of left and right eyes of the first user further includes:

when a second user other than the first user is absent in the vehicle, determining whether current time is nighttime; and

when the current time is the nighttime, distinguishing the true pair of left and right eyes of the first user based on the dimension of each of the at least two pairs of left and right eyes, and based on the distance between each of the at least two pairs of left and right eyes and the stereoscopic cluster.

18. The method of claim 17 , wherein distinguishing the true pair of left and right eyes of the first user further includes:

when the current time is daytime, determining a current state as an abnormal state; and

providing a two-dimensional (2D) screen for the first user.

19. The method of claim 18 , further comprising:

continuously determining, by the processor, whether the second user is present in the vehicle and determining the current time while the 2D screen is being presented; and

when the continuously determining the current time determines that the abnormal state returns to a normal state, providing a pop-up for changing the 2D screen to a stereoscopic screen.

20. The method of claim 16 , wherein the determining the presence or absence of the second user includes:

determining whether the second user other than the first user is present in the vehicle based on a received sensed value from an ultrasonic sensor for sensing movement within the vehicle, or from a mat sensor for sensing whether a corresponding seat is seated,

wherein the providing the stereoscopic screen includes controlling a barrier based on a position of the true pair of left and right eyes of the first user.
