Illustratively, it in the present embodiment, based on pre-set image generating algorithm and default row's graph parameter, generates with array shape
Formula arrangement periodically variable pattern image before, can by default row's graph parameter range according to the identical division of screen
Rule is divided so that the multiple default row's graph parameters obtained after division are corresponding with multiple array regions in screen.Its
In, the sub-pixel for belonging to the same array region corresponds to same default row's graph parameter, to obtain the sample of array format arrangement
Formula image.Setting in this way avoids in detection process every time the default row's graph parameter of only detection one really row schemes to join with display screen
Several degree of closeness, so as to the detection efficiency of the row's of raising graph parameter.
Wherein, the row's of presetting graph parameter ranging from empirical value, display screen really arrange the figure period positioned at default row's graph parameter model
In enclosing.

When black and white strip cannot be presented in column region, illustrate that default row's graph parameter of the array region really arranges graph parameter phase with display screen
Difference is larger, it is difficult to form Morie fringe, and if when carrying out row's figure with default row's graph parameter of the array region, can not generate good
Good bore hole 3D effect.Black and white strip due to a cycle is by can in each array region of detection image after Grating Film
It can show the black and white strip in multiple periods, i.e. Morie fringe, and work as the number of cycles of black and white strip in some array region most
When few, illustrate the black and white strip relative to a cycle in other array regions, the black and white item of a cycle in the array region
The width of line is maximum, therefore the default row's graph parameter that also can be explained corresponding to the array region really arranges graph parameter with display screen
It is closest.At this point, can be using the default row's graph parameter generated corresponding to the maximum black and white strip of width as the target of display equipment
