Calculation it is consistent.
Multiple pixels in group left-eye image have different pixel value, the multiple pixels in sub- eye image
Can be correspondence each pixel calculating crosstalk pixel value, for example, with certain sub- eye image with different pixel value
First pixel calculates crosstalk ratio and obtains first pixel of first pixel to other left-eye images in the eye image
Point crosstalk pixel value, other pixels are similarly.It can also be the average pixel value conduct that corresponding subgraph is multiplied by with crosstalk ratio
Crosstalk pixel value.
Step S130：Corresponding crosstalk is subtracted from left-eye image and eye image in each frame image to be shown
Pixel value, obtains each frame corresponding display image of image to be shown.
Subtracting corresponding crosstalk pixel value from left-eye image and eye image in each frame image to be shown can
To be：The crosstalk pixel value of corresponding sub- eye image is subtracted from each sub- left-eye image, from each sub- eye image
In subtract the crosstalk pixel value of corresponding sub- left-eye image.Specifically, every pixel value of each pixel of sub- left-eye image
Corresponding crosstalk pixel value is subtracted, the pixel value of every each pixel of sub- eye image subtracts corresponding crosstalk pixel value.
When each pixel calculating crosstalk pixel value is corresponded to, it is right to be subtracted from each pixel in every sub- left-eye image
The crosstalk pixel value that the pixel of correspondence position is calculated in the sub- eye image answered, from each in every sub- eye image
Pixel subtracts the crosstalk pixel value that the pixel of correspondence position in corresponding sub- left-eye image is calculated.For example, certain height
First pixel of left eye subtract for first pixel of corresponding eye image is multiplied by the crosstalk picture that crosstalk ratio is obtained
Element value, other each pixels are similarly.
Step S140：Control 3D display devices show to each frame display image.
