Embodiment

[0092] When using the LCD screen to expose and image, if only relying on the pixels of the screen itself, the number of pixels is not enough; at the same time, there are certain gaps between the pixels on the screen, which leads to grids on the microfilm, in order to make up for this Two defects, the present invention adopts the moving screen interpolation algorithm to solve related problems.

[0093] First, we acquire the image and enlarge it: after 9 exposures, the width and height of the image will be enlarged by 3 times at the same time; and so on.

[0094] Then, we sequentially display the separated small images on the screen for exposure, and at the same time of each exposure, the micro-displacement structure cooperates to move the LCD screen, so that the landing points of multiple exposures of the same pixel point on the LCD screen are evenly filled. In the horizontal and vertical grids generated by the pixel pitch on the screen, we not only increase the number of expos...

Abstract

The present invention provides a high-resolution liquid crystal screen display exposure processing method for microarchitecture equipment, and proposes a screen-shifting interpolation algorithm to solve this defect; first, acquire an image and enlarge the image: 9 exposures, and simultaneously enlarge the image width and height by 3 times ;Secondly, divide the enlarged image into 9 images according to the division steps described above; then, sequentially display the divided small images on the screen for exposure, and move the LCD screen slightly in one direction at the same time as each exposure, Move the pixels on the screen in the other direction, so that the multiple exposure points of the same pixel on the LCD screen are evenly filled into the horizontal and vertical grids generated by the pixel spacing on the screen, which increases the number of exposed pixels Number, and inhibit the appearance of the grid, thereby improving the quality of film micro-imaging.

Description

technical field [0001] The invention relates to the technical field of display pixel compensation exposure, in particular to a pixel compensation exposure processing method for microarchitecture equipment. Background technique [0002] Conventional XGA-level LCD screens have a resolution of 1280x1024 or 1600x1200 and a small imaging area, while QXGA-level LCD screens have a resolution above 2048x1536. Increases in resolution have resulted in improvements in the quality of microfilm exposures. However, only relying on the physical resolution of the 5K LCD screen for miniaturization and archiving, the dpi after miniaturization is very low. Far below the standard of imported equipment. To solve this problem, we found that the pixels on the LCD screen are usually composed of three RGB sub-pixels, we can regard each pixel as three pixels, so that each row of pixels on the LCD screen is equivalent to becoming The previous three times, when displaying the exposure, we will no lo...
