Problems solved by technology

[0002] In the process of 3D display, it is necessary to provide left-eye images and right-eye images to the left and right eyes of the viewer, but due to various reasons, the left eye of the viewer sees a certain amount of content in the right image, and the right eye sees a certain amount of content. The content of the left eye will cause double image phenomenon (or called ghost image) in the 3D scene, that is, "crosstalk" occurs
The existence of crosstalk greatly affects the quality of 3D display

Embodiment 1

[0131] Example 1: Regardless of the control module

[0132] When the control module is not considered, that is, the corresponding weight factor γ=0, the calculation formula (3) is further changed to:

[0133] A=S1*|P-L|+S2*|P-R|≥0 (4)

[0134] For the convenience of description, the following discussion will be carried out according to the size of L and R.

[0135] (1) L≤R

[0136] Since the display value P must be between L and R when the display unit is finally displayed, that is, L≤P≤R, the calculation formula (4) is further simplified as:

[0137] A=(S1-S2)*P-(S1*L-S2*R)≥0

[0138] When A takes the minimum value, that is, A=0, then in the case of S1-S2≠0:

[0139] P = S 1 * L - S 2 * R S 1 - S 2 ...

Embodiment 2

[0156] Example 2: Consider the control module

[0157] Preferably, the calculation formula of the total crosstalk amount may be adjusted according to the difference between the first crosstalk amount and the second crosstalk amount, so as to balance the first crosstalk amount and the second crosstalk amount; and calculating the optimal display value according to the adjusted total crosstalk amount.

[0158] Wherein, the control module may be the difference corresponding to the first crosstalk amount and the second crosstalk amount, by adding the difference corresponding to the first crosstalk amount and the second crosstalk amount to the calculation formula of the total crosstalk amount value of the balance control parameter, and by controlling the weight of the balance control parameter, the size of the control module's role in the total crosstalk can be adjusted.

[0159] By adding a balance control parameter, the consideration of the difference between the first crosstalk ...

Abstract

The invention provides a three-dimensional display method which includes the steps that the interference value of a display unit, under covering of a light splitting device, for at least a pair of images with parallax is obtained; according to the interference value, the display unit is adjusted; the adjusted display unit is used for displaying the pair of images with parallax. The invention further provides a three-dimensional display device. According to the technical scheme, the crosstalk phenomenon can be effectively reduced in the process of three-dimensional display, and the three-dimensional display effect is optimized.

Description

technical field [0001] The present invention relates to the technical field of stereoscopic display, in particular to a stereoscopic display method and a stereoscopic display device. Background technique [0002] In the process of 3D display, it is necessary to provide left-eye images and right-eye images to the left and right eyes of the viewer, but due to various reasons, the left eye of the viewer sees a certain amount of content in the right image, and the right eye sees a certain amount of content. If the content of the left eye of the 3D scene is not displayed, it will cause double image phenomenon (or called ghost image) in the 3D scene, that is, "crosstalk" occurs. The existence of crosstalk greatly affects the quality of 3D display. [0003] Therefore, how to reduce the crosstalk existing in the 3D display process has become an urgent technical problem to be solved. Contents of the invention [0004] The present invention aims to solve at least one of the techni...
