Measuring method of left and right eye brightness crosstalk values of stereoscopic display device

Abstract

The invention relates to a measuring method of left and right eye brightness crosstalk values of a stereoscopic display device. The method comprises the following steps that: step 1, a test chart is displayed on a stereoscopic television or a stereoscopic display and is divided into two parts: a left image and a right image, wherein corresponding test units are respectively arranged in the left image and the right image as well as first areas and second areas are arranged in the test units; step two, a crosstalked image is used as a right image and a crosstalking image is used as a left image, so that a brightness crosstalk value from a left eye to a right eye is obtained; and step three, an input signal is changed as well as the crosstalked image is used as a left image and the crosstalking image is used as a right image, so that a brightness crosstalk value from a right eye to a left eye is obtained. According to the invention, beneficial effects are as follows: the measuring steps are simple; there is no need to change an input signal frequently; and because a brightness difference deduction method is employed, same interference factors can be counteracted during the calculation process, so that the requirement on the measuring environment during the measuring process is not strict.

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 measurement of the image quality of 3D TVs has also been put on the agenda accordingly. The degree of luminance 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 device-Part 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 stipulates a method for measuring left and right eye luminance crosstalk in a stereoscopic display that requires glasses to separate left and right eye images: [0003] a): Use a 4% white window signal as the left...
