Three dimensional image display method and device utilizing a two dimensional image signal at low-depth areas

摘要

A 3D image display device includes a display unit including a display panel and an optical panel located at a front side of the display panel and changing a path of light. A controller is configured to generate a signal for controlling the display unit. The controller includes an image signal processor which generates an input image signal based on image information containing 2D image information and depth information. The image signal processor generates a 3D image signal based on the 2D image information and the depth information. The image signal processor extracts a low-depth area having a small depth and generates a 2D image signal corresponding to the low-depth area. The display unit displays the low-depth area by a 2D image.

1. A 3D image display device, comprising:
a display unit including a display panel and an optical panel, the display panel including a plurality of pixels and the optical panel disposed at a front side of the display panel and configured to selectively change a path of light emanating from the display panel; and a controller configured to generate a signal for controlling the display unit, wherein the controller includes an image signal processor generating an input image signal based on image information including two-dimensional (2D) image information and depth information, wherein the image signal processor generates a three-dimensional (3D) image signal based on the 2D image information and the depth information, wherein the image signal processor extracts a low-depth area having a smaller absolute value of a depth than a reference value and generates a 2D image signal corresponding to the low-depth area, and wherein the display unit displays the low-depth area as a 2D image, wherein the image signal processor divides the low-depth area into a plurality of sub areas according to a depth thereof, and generates the 2D image signal which gradually decreases resolution for each of the sub areas, and wherein the image signal processor generates the 2D image signal which gradually decreases resolution for each of the sub areas as a depth of the sub area becomes larger to smooth the resolution difference at a boundary between the 2D image and a displayed 3D image.
