Abstract

According to an embodiment, a stereoscopic image display apparatus includes: a measurement module configured to measure a distance from a display screen to stereoscopic image eyeglasses, and an angle of the stereoscopic image eyeglasses with respect to a normal to the display screen; and a converter configured to convert a plane image into a stereoscopic image based on the distance and the angle.

Claims

1. A stereoscopic image display apparatus, comprising:

a measurement module configured to measure a distance from a display screen to stereoscopic image eyeglasses, and an angle of the stereoscopic image eyeglasses with respect to a normal to the display screen; and

a converter configured to convert a plane image into a stereoscopic image based on the distance and the angle.

2. The apparatus of claim 1, further comprising:

a receiving module configured to receive, from the stereoscopic image eyeglasses, wearing state information representing that a user wears the stereoscopic image eyeglasses,

wherein the measurement module measures, after receiving the wearing state information, the distance and the angle.

3. The apparatus of claim 1,

wherein the measurement module measures the distance of the stereoscopic image eyeglasses from a substantial center of the display screen and the angle of the stereoscopic image eyeglasses with respect to the normal to the display screen at the substantial center thereof.

4. The apparatus of claim 1, further comprising:

a front surface cover,

wherein the measurement module is on a front surface cover at a central upper portion or a central lower portion thereof.

5. The apparatus of claim 1, further comprising:

a parameter generator configured to generate a parameter based on the distance and the angle,

wherein the converter converts the plane image into the stereoscopic image based on the parameter.

6. The apparatus of claim 5,

wherein the parameter generator generates a depth parameter and a parallax parameter.

7. The apparatus of claim 6,

wherein the depth parameter is determined by a value of a distance from the stereoscopic image eyeglasses to a foot of a normal to the display screen.

8. The apparatus of claim 6,

wherein the parallax parameter is determined by a magnitude of the angle of the stereoscopic image eyeglasses with respect to the normal to the surface of the display screen.

9. Stereoscopic image eyeglasses, comprising:

a detector configured to detect a wearing state of the user upon blocking of a light traveling from a light emitter to a light receptor; and

a transmission module configured to transmit, to a stereoscopic image display apparatus, a wearing state information representing that the user wares the stereoscopic image eyeglasses.
