Problems solved by technology

Therefore, since the existing method for evaluating 3D crosstalk does not consider the actual use environment of the stereoscopic image display, it cannot accurately evaluate the 3D crosstalk at each of all representable gray levels of the stereoscopic image display.

Abstract

A system and a method for evaluating a crosstalk of a stereoscopic image display are disclosed. The crosstalk evaluation system includes a display element that alternately display left and right eye images each having an i-gray level and a j-gray level, where ''i'' and ''j'' are an integer, a luminance meter sensing luminances of the left and right eye images displayed on the display element, and a computer that calculates a 3D crosstalk at the i-gray level of the left eye image affected by the j-gray level of the right eye image and a 3D crosstalk at the i-gray level of the right eye image affected by the j-gray level of the left eye image based on a luminance information received from the luminance meter while changing the i-gray level and the j-gray level.

Description

technical field [0001] Embodiments of the invention relate to systems and methods for evaluating crosstalk for stereoscopic image displays. Background technique [0002] Stereoscopic image displays are classified into those using stereoscopic technology and those using autostereoscopic technology. [0003] A stereoscopic technique using a parallax image with a high stereoscopic effect between a user's left and right eyes includes a glasses-type method and a non-glasses-type method. In the glasses-type method, the parallax image between the left eye and the right eye is displayed on a direct-view display or a projector by a change in the polarization direction of the left and right parallax images or in a time-division manner, so polarization glasses or shutter glasses are used to Achieve stereoscopic images. In the non-glasses type method, an optical plate such as a parallax barrier and a lenticular lens is generally used to divide an optical axis of a parallax image betwe...
