Method for measuring left-right-eye luminance crosstalk values of three-dimensional display device

Abstract

The invention relates to a method for measuring left-right-eye luminance crosstalk values of a three-dimensional display device. The method includes the following steps: (1) displaying a test image on the three-dimensional television or the three-dimensional displayer, wherein the test image is divided into a left image body and a right image body, the left image body and the right image body are provided with corresponding test units respectively, and each test unit is provided with a first area and a second area; (2) enabling an image influenced by the crosstalk to serve as the right image body, enabling an image applying the crosstalk to serve as the left image body, and obtaining the luminance crosstalk value from the left eye to the right eye; (3) changing an input signal, enabling the image influenced by the crosstalk to serve as the left image body, enabling the image applying the crosstalk to serve as the right image body, and obtaining the luminance crosstalk value from the right eye to the left eye. The method has the advantages that the measuring steps are simple; the input signal is not required to be frequently changed; due to the adoption of a luminance difference dividing method, same interference factors in the computing process can be counteracted, and therefore the requirement for the measurement environment during measuring is not high.

Description

technical field [0001] The invention relates to a method for measuring brightness crosstalk values ​​of left and right eyes of a stereoscopic display device. Background technique [0002] As the 3D TVs of major TV brands at home and abroad are successively put into the market, the image quality measurement of 3D TVs has also been put on the agenda accordingly, and the brightness crosstalk between the left and right eyes of the 3D display is one of the important testing items. The existing international measurement standard IEC 2009 3D display devicePart x-x: Optical measuring methods for stereoscopic displays using glasses (in line with IEC 2009 3D display device Part XX: optical measurement stereoscopic glasses display method), in Chapter 6, Section 5 It stipulates a measurement method of left and right eye luminance crosstalk for stereoscopic display that requires glasses to separate left and right eye images as follows: [0003] a): Use a 4% white window signal as the le...
