Abstract

A stereoscopic image display includes a depth map extracting unit for extracting a region of interest (ROI) and a depth map from a 3D input image, an average depth for calculating unit calculating an average depth of the ROI, a depth map adjusting unit, which converts the average depth of the ROI into a screen depth value of a display panel, shifts depth values of the 3D input image in a shift direction of the average depth by a shifted amount of the average depth of the ROI, and adjusts a depth map of the 3D input image, a left/right eye image producing unit for producing left eye image data and right eye image data based on the adjusted depth map, and a display panel driver for displaying the left eye image data and the right eye image data on the display panel.

Claims

1. A stereoscopic image display comprising:

an ROI and depth map extracting unit configured to extract a region of interest (ROI) and a depth map from a 3D input image;

an average depth calculating unit configured to calculate an average depth of the ROI;

a depth map adjusting unit configured to convert the average depth of the ROI into a screen depth value of a display panel, shift depth values of the 3D input image in a shift direction of the average depth by a shifted amount of the average depth of the ROI, and adjust a depth map of the 3D input image;

a left/right eye image producing unit configured to produce left eye image data and right eye image data based on the depth map adjusted by the depth map adjusting unit; and

a display panel driver configured to display the left eye image data and the right eye image data received from the left/right eye image producing unit on the display panel.

2. The stereoscopic image display of claim 1, further comprising a 2D-3D image converter configured to convert a 2D input image into the 3D input image.

3. The stereoscopic image display of claim 1, wherein the display panel is implemented as a display panel of one of a liquid crystal display (LCD), a field emission display (FED), a plasma display panel (PDP) display, an electroluminescence device (EL), and an electrophoresis display (EPD).

4. A method of adjusting a stereoscopic image of a stereoscopic image display, the method comprising:

extracting a region of interest (ROI) and a depth map from a 3D input image;

calculating an average depth of the ROI;

converting the average depth of the ROI into a screen depth value of a display panel and shifting depth values of the 3D input image in a shift direction of the average depth by a shifted amount of the average depth of the ROI to adjust a depth map of the 3D input image;

producing left eye image data and right eye image data based on the adjusted depth map; and

displaying the left eye image data and the right eye image data on the display panel.

5. The method of claim 4, further comprising converting a 2D input image into the 3D input image.
