Embodiment Construction

[0041] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0042] As the first aspect of the technical solution of the present invention, a method for generating a signal for measuring the crosstalk value of the left and right eyes is provided, and the specific steps are as follows:

[0043] In the first step, at least two brightness values ​​are selected and arranged to form a crosstalk source signal with background brightness and light and dark stripes.

[0044] In the second step, the crosstalked signal is generated according to the crosstalked source signal:

[0045] The brightness value of the background brightness of the selected crosstalk source signal is used as the background brightness of the crosstalk signal;

[0046] At least one crosstalk value is selected, an...

Abstract

The invention relates to a method for generating a signal for measuring a left and right eye crosstalk value, and the method comprises the following steps that at least two brightness values are selected first; the two brightness values are lined, and a crosstalk source signal with background brightness and light and dark stripes is formed; then a signal subjected to crosstalk is generated according to the crosstalk source signal; the brightness value of the background brightness of the crosstalk source signal is selected as the background brightness of the signal subjected to crosstalk; and at least one crosstalk value is selected, and the brightness values of the light and dark stripes of the signal subjected to crosstalk are calculated according to the crosstalk value. In addition, the invention also provides a method for measuring the left and right eye crosstalk value through the crosstalk source signal and the signal subjected to crosstalk. The technical scheme of the invention provides the direct-reading crosstalk value measuring method and the method for generating the testing signal required for the measuring method. No brightness meter and other auxiliary tools need to be adopted, meanwhile the requirements on the measurement environment are reduced, and a measuring process can be completed not necessarily in a darkroom environment. According to the method for generating the signal for measuring the left and right eye crosstalk value and the method for measuring the crosstalk value, a testing operation process is simplified, and the crosstalk value can be read intuitively and quickly without a lot of complicated calculation.

Description

technical field [0001] The invention relates to a method for generating a signal for measuring the crosstalk value of left and right eyes and a method for measuring the crosstalk value of left and right eyes. Background technique [0002] The luminance crosstalk between the left and right eyes of the stereoscopic display, including the luminance crosstalk from the left eye to the right eye and the luminance crosstalk from the right eye to the left eye, is a common problem in current stereoscopic displays. In general, the main reason for luminance crosstalk is that the image for the left eye does not completely enter the left eye, but part of it enters the right eye; while the image for the right eye does not completely enter the right eye, but part of it enters the left eye. For a stereoscopic display, the strength of the crosstalk directly affects the quality of its stereoscopic effect. Therefore, the degree of luminance crosstalk between the left and right eyes of the ste...
