Embodiment
When using liquid crystal display exposure image, if single by the pixel of itself is shielded, the quantity of pixel is inadequate；Together
When, there is certain gap between on-screen pixels point, this causes that grid can be produced on fiche, lack to make up the two
Fall into, the present invention solves relevant issues using screen interpolation algorithm is moved.
First, we obtain image and image are amplified：9 exposures, just by wide high 3 times of the amplification simultaneously of image；According to
It is secondary to analogize.
Then, we include the small image separated exposing on screen successively, and micro-displacement knot while each exposure
The cooperation mobile liquid crystal screen of structure so that the drop point of the multiexposure, multiple exposure of same pixel just uniformly inserts on-screen pixels on liquid crystal display
In the horizontal and vertical grid that point spacing is produced, so we had both increased the pixel count for exposure of knowing clearly, and grid is inhibited again
Occur, so as to improve the miniature quality of film.
Screen interpolation algorithm is moved by taking 9 times (N=9) exposure as an example, main the following steps of implementing can be completed：
(1) image is obtained, and image is wide high while 3 times of amplification；
(2) broken away view picture is 9；
(3) mobile liquid crystal screen；
(4) the R colors of component are shown on screen, exposed；
(5) the G colors of component are shown on screen, exposed；
(6) the B colors of component are shown on screen, exposed；
(7) (3), (4), (5) and (6) step 9 time is repeated, you can complete the exposure of 9 components.
The application of micro-displacement interpolation algorithm is initially the liquid crystal display that a pixel is represented for a point, and high resolution liquid
On the screen of crystalline substance screen, a pixel by representing what three points of RGB component were constituted respectively, and such three arranged in a straight line side by side
The characteristics of point one pixel of composition, make it that we require further improvement shifting screen interpolation algorithm to adapt to big resolution liquid crystal display
Exposure display.
First, the acquisition, amplification and component of image are proceeded as before (exemplified by being divided into 9)；
Secondly as 5K resolution liquid crystal display pixel point ranges are closely spaced, and each pixel is made up of the color dots of RGB tri-,
So we can regard each pixel as three pixels, the often row pixel so shielded is equivalent to before becoming
Three times, when showing exposure, we no longer will longitudinally move screen, but by all pixels of corresponding three components respectively with screen
R color dots, G color dots and the B color dots of upper each pixel show to replace longitudinal direction to move screen (i.e.：Assuming that have 3 components T1, T2 and T3, I
Show T1 with the R points of the upper all pixels of screen respectively, G points show that T2 and B points show T3), moreover, we can expose every time
Shi Yici exposes three components (i.e.：Three components of the row of colleague are simultaneously displayed on screen simultaneously, while R is exposed, while exposing G, simultaneously
Expose B), and then 3 times will be shortened the time for exposure.
On high resolution liquid crystal display in the arrangement of pixel, between-line spacing is larger, so not only to carry out shifting screen, and adopts
Grid is handled with the mode for repeating to move screen.
First, amplification and the component of image are proceeded as before (exemplified by being divided into 9)；
Secondly, three constitutional diagrams separated (every group of three small image for colleague is constituted) are shown on screen successively and exposed,
And cooperation mobile liquid crystal screen while each exposure slightly；Then, after laterally having moved three times, by owning for 9 components
Pixel moves up a row, and repeats a previous step.
Screen interpolation algorithm is moved by taking 9 times (N=9) exposure as an example, in exposure pretreatment subprogram, the picture of conversion is divided into as follows
Nine：
