Abstract

A 3D image display device is provided. The 3D image display device can sense a posture change of a 3D display using a gyro-sensor and prevent an image for an LE and an image for an RE from being converted using a sensed posture change. The 3D image display device includes a main body a multi-view type display, a gyro-sensor, and an image-conversion controller. The multi-view type display provides a 3D image for an LE and a 3D image for an RE. The gyro-sensor is mounted in the main body to sense a posture change of the display and the image-conversion controller prevents conversion of a provided 3D image using the posture change of the display sensed by the gyro-sensor. Therefore, an image signal for an RE and an image signal for an LE are provided to viewing regions where an RE and an LE of a viewer are located, so that the viewer can view a 3D image properly.

Claims

1. A 3D image display device comprising:

a main body;

a multi-view type display providing a 3D image for a left eye and a 3D image for a right eye;

a gyro-sensor mounted in the main body and sensing a posture change of the display; and

an image-conversion controller preventing conversion of a 3D image using a posture change of the display sensed by the gyro-sensor, so that a viewer views an image signal for a left eye and an image signal for a right eye in a viewing region where a right eye and a left eye of the viewer are positioned.

2. The 3D image display device of claim 1, further comprising:

a reset part setting an initial value of the gyro-sensor that sets an arbitrary position of the display to an initial position by selection of a viewer.

3. The 3D image display device of claim 2, wherein the image-conversion controller comprises a signal-conversion part converting an image signal for a left eye and an image signal for a right eye, the controller sensing a relative position change of the display with respect to the viewer using the gyro-sensor to judge whether a left eye and a right eye of the viewer are positioned in an initial viewing region for a right eye and an initial viewing region for a left eye, respectively;

when the left eye is positioned in a viewing region for the right eye and the right eye is positioned in a viewing region for the left eye, an image signal for a left eye and an image signal for a right eye are converted to each other using the signal conversion part so as to prevent left-right conversion of a provided 3D image.

4. The 3D image display device of claim 1, wherein the image-conversion controller comprises a signal-conversion part converting an image signal for a left eye and an image signal for a right eye, the controller sensing a relative position change of the display with respect to the viewer using the gyro-sensor to judge whether a left eye and a right eye of the viewer are positioned in an initial viewing region for a right eye and an initial viewing region for a left eye, respectively;

when the left eye is positioned in the viewing region for the right eye and the right eye is positioned in the viewing region for the left eye, an image signal for a left eye and an image signal for a right eye are converted to each other using the signal conversion part so as to prevent left-right conversion of a provided 3D image.

5. The 3D image display device of claim 1, wherein the gyro-sensor is mounted within or on an exterior of the main body.

6. The 3D image display device of claim 1, wherein the display comprises:

a screen mounted within the main body and on which 3D image data selected by the controller is projected; and

a viewing region-separation part separating the 3D image projected on the screen into an image for a left eye and an image for a right eye.
