Embodiment Construction

[0035] 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.

[0036] The method for generating and measuring the left and right eye crosstalk value signals of the present invention, the specific steps are as follows:

[0037] 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.

[0038] In the second step, the crosstalked signal is generated according to the crosstalked source signal:

[0039] The brightness value of the background brightness of the selected crosstalk source signal is used as the background brightness of the crosstalk signal;

[0040] At least one crosstalk value is selected, and brightness values ​​of bright and dark stripes of the crosstalked si...

Abstract

The invention relates to a method for generating and measuring a left and right eye crosstalk value signal, which comprises the following steps of: firstly, selecting at least two brightness values and arranging at least two brightness values to form a crosstalk source signal with background brightness and light and dark strips; and then generating an interfered signal according to the crosstalk source signal, using the brightness value of the background brightness of the crosstalk source signal as background brightness of the interfered signal, selecting at least one crosstalk value and calculating a brightness value of the light and dark strips of the interfered signal according to the crosstalk value. When the signal generated by the technical scheme disclosed by the invention is adopted to measure a left and right eye crosstalk value, auxiliary tools such as a brightness meter and the like are not required, direct-read measurement is realized, the requirement on the measurement environment also can be reduced, and the crosstalk value measurement is not required to be completed in the darkroom environment. According to the invention, the technical basis is provided for the crosstalk value measurement, the testing operation process is simplified, and the crosstalk value can be visually, rapidly and conveniently read without massive complex 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. 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 stereoscopic display has become an important index for evaluating the ima...
