Abstract:
1. A 3D image display device comprising: a main body; a multi-view type display which provides a 3D image for a left eye and a 3D image for a right eye; a gyro-sensor which is mounted in the main body and senses a posture change of the display; and an image-conversion controller which prevents conversion of a 3D image using the posture change of the display sensed by the gyro-sensor, so that a viewer views an image signal for the left eye and an image signal for the right eye in a viewing region where the right eye and the left eye of the viewer are positioned, wherein the image-conversion controller comprises a signal-conversion part which converts an image signal for the left eye and an image signal for the right eye, the controller senses a relative position change of the display with respect to the viewer using the gyro-sensor to judge whether the left eye and the right eye of the viewer are positioned in an initial viewing region for the right eye and an initial viewing region for the left eye, respectively, and 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 the left eye and an image signal for the right eye are converted to each other using the signal-conversion part so as to prevent left-right conversion of a provided 3D image.
