Abstract

A hardware system for inputting a 3D image in a flat panel includes: a 3D image source input unit which is mounted on a 3D monitor equipped with a lenticular lens for transferring a left eye image and a right eye image on a front surface of an LCD panel, respectively, to viewer'"'"'s left eye and right eye and receives a 3D image in a side by side form in which a left eye image and a right eye image are combined in parallel left and right from a 3D image reproducing device, which is externally connected to the 3D monitor, through an image input terminal; and a viewer position tracker which is mounted on the 3D monitor to track, in real time, a viewer'"'"'s position from an image photographed by a camera photographing a front of the 3D monitor.

Claims

1. A hardware system for inputting a three-dimensional (3D) image in a flat panel, comprising:

a 3D image source input unit which is mounted on a 3D monitor equipped with a lenticular lens for transferring a left eye image and a right eye image on a front surface of an LCD panel, respectively, to viewer'"'"'s left eye and right eye and receives a 3D image in a side by side form in which a left eye image and a right eye image are combined in parallel left and right from a 3D image reproducing device, which is externally connected to the 3D monitor, through an image input terminal;

a viewer position tracker which is mounted on the 3D monitor to track, in real time, a viewer'"'"'s position from an image photographed by a camera photographing a front of the 3D monitor;

a 3D image processor which separates the left eye image and the right eye image from the 3D image in the side by side form which is input through the 3D image source input unit, cuts the separated left eye and right eye images in a slit form, alternately combines the cut left eye image and right eye image slits to generate one 3D image, transmits the generated 3D image to the LCD panel of the 3D monitor through a low voltage differential signaling (LVDS) interface to display the 3D image on the LCD panel, adjusts coordinates of pixels of the left eye image and right eye image slits displayed on the LCD panel of the 3D monitor according to position coordinates of the viewer tracked in real time by the viewer position tracker to allow the viewer to view the 3D image anywhere; and

a 3D image preprocessor which checks whether or not the 3D image data input from the 3D image source input unit is replicated, if the input 3D image data is not replicated, separates an audio signal included in the 3D image data from the 3D image, corrects the 3D image for enhancing resolution of the separated 3D image, adjusts a size of the corrected 3D image, and transmits the resized 3D image to the 3D image processor.

2. The hardware system of claim 1, wherein the viewer position tracker includes:

an image sensing module which photographs a viewer who watches the 3D monitor and then generates the photographed image of the viewer;

a viewer'"'"'s photographed image transmitter which transmits the image photographed by the image sensing module to the 3D image processor through a mobile industry processor interface (MIPI) and a camera serial interface-1 (CSI-1); and

a viewer-tracking processor which tracks the position coordinates of the viewer in the photographed image of the viewer input to the 3D image processor.

3. The hardware system of claim 1, wherein the viewer position tracker tracks in real time a whole body of the viewer, a face of the viewer, or a binocular position coordinates from the image photographed by the camera which photographs the front of the 3D monitor.
