Abstract

In a three-dimensional image generating apparatus, a luminance gradient calculating portion calculates a luminance gradient, which indicates the amount of change in luminance between a pixel of interest and a pixel adjacent thereto, a right-eye image generating portion corrects a pixel luminance in a correction amount having the same sign as the luminance gradient, and a left-eye image generating portion corrects a pixel luminance in a correction amount having the opposite sign to the luminance gradient. As a result, there is a difference in luminance distribution between left-eye and right-eye images, so that stereoscopic viewing is made possible without calculating depth information, and there is no change in pixel positions, so that the images do not appear doubled or they are resistant to appearing doubled.

Description

technical field [0001] The present invention relates to a method for generating a stereoscopic image, and more particularly, to a method for generating a stereoscopic image that can be viewed stereoscopically from a planar (two-dimensional) image, a generating device thereof, and a display device including the same. Background technique [0002] In recent years, a large number of display devices capable of stereoscopic viewing such as 3D television devices have been sold. This 3D television device performs stereoscopic display based on a video source such as a 3D movie configured in advance to enable stereoscopic display. [0003] However, in general television broadcasting, a two-dimensional image (planar image) that is not configured to be displayed stereoscopically is provided. Therefore, it is desired to generate a stereoscopic image that can be displayed stereoscopically from the planar image. [0004] Conventionally, there are various methods for converting a planar i...
