The left-eye image and eye image of diagram picture.
First stereoscopically displaying images and second stereoscopically displaying images include left-eye image and eye image respectively,
Preparatory condition whether is met to determine in the following ways：The pixel count of first pixel and the left-eye image in the left-eye image
Total pixel number the first current percentage, the pixel count of the second pixel and the total pixel of the eye image in the eye image
The second several current percentage, wherein, first pixel is different from second pixel.
According to the described first current percentage, the second current percentage and the first current percentage with it is described
Preset relation between second current percentage obtains value to be compared, judges whether the value to be compared is more than or equal to correspondence default
Threshold value.The preset relation is that the preset relation is between the described first current percentage and the second current percentage
And, at least one of product, average or extreme value.The preparatory condition refers to：The first current percentage, described
Two current percentage products are greater than equal to the default threshold value of the correspondence.
Tell about in detail below and whether meet preparatory condition determination usual practice really：
The left-eye image that stereoscopic display device is shown first is the first color image, and eye image is the second color image, first
Color image is different from the second color image.Alternatively, when the first color image is a kind of in red (R), green (G), blue (B),
Second color image be it is remaining two kinds in red (R), green (G), blue (B) in one of which, that is, pixel it is different.Here
Illustrated so that left-eye image is red image, eye image is green image as an example.
First camera and the 3rd camera shoot left-eye image respectively, referred to as left camera, second camera and the 4th
Camera shoots eye image respectively, referred to as right camera.If there is crosstalk, then the image that left camera is photographed will not be complete
Portion is red pixel, has part-green pixel；And the image that right camera is photographed will not be entirely green pixel, portion is had
Dividend color pixel.
A comprehensive value model value P can be set0, by the comprehensive evaluation value P of shooting picture1With comprehensive value model
Value P0It is compared, if P1≥P0, then it is assumed that left camera photographs complete red picture, and right camera photographed complete green picture.Calculate
P1There are following two methods：
(1) if left camera and right camera photographed red image and the green image that stereoscopic display device is shown respectively,
Processing unit handles red image and green image respectively.Here be with left camera shoot image according to red pixel quantity
Calculate, the image that right camera is shot is calculated according to green pixel quantity.
Number R1, the green pixel number G1 of red pixel in the left-eye image that left camera is shot are calculated, the right side is calculated and takes the photograph
As the number G2 for the eye image Green pixel that head is shot, the number R2 of red pixel, left-eye image sum of all pixels and right eye
The sum of all pixels of image is identical, is M, comprehensive evaluation value P1=(R1/M) * (G2/M), then according to the overall merit mark of setting
Quasi- value P0, P0Span be 0~1.Specific value can foundation：Camera is to red green sensitivity and ambient light
The factor sets itselfs such as line, the parameter of camera lens, for example：Light is too strong, and it is too big that lens aperture is adjusted, and causes the red photographed to be lost
Very, now user can be by P0Numerical value set it is smaller.If P1≥P0, then it is assumed that left camera photographs complete red picture, and the right side is taken the photograph
As head photographed complete green picture.
(2) if there is non-black background in left-eye image and eye image, red pixel or green pixel can be influenceed
Evaluation, cause the change of R or G pixel quantities to become greatly, being produced on overall result of calculation influences.So in order to more accurate
R and B quantity is calculated, can be further comprising the steps of using method is calculated as below：
Figure step is scratched, by the difference of image pixel value, the edges of regions position of shooting picture image is determined, then plucks out
The green image region in red image region and eye image in left-eye image.Then calculate red in red image region
The number r1 of pixel, the number g1 of green pixel, calculate the number g2 of green image region Green pixel, of red pixel
Number r2, view picture scratches figure image pixel number m, comprehensive evaluation value P1=(r1/m) * (g2/m), then according to the overall merit of setting
Standard value P0, P0Span be 0~1.If P1≥P0, then it is assumed that left camera photographs complete red picture, and right camera was photographed
Complete green picture.
Moreover, it is judged that the method whether stereoscopically displaying images of collection meet preparatory condition is not limited to the above method,
Also other various ways, for example：(1) image is being calculated after being converted into extended formatting, for example changes into RGB after HSV
Calculate again；(2) standard value (sum of all pixels in i.e. whole sub-picture) is adjusted according to the feature of image at any time at any time, then calculated
Ratio of the single pixel in whole image sum of all pixels.
