Embodiment Construction

[0051] When using LCD exposure imaging, if relying solely 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 photo, in order to make up for these two Defect, the present invention adopts screen-moving interpolation algorithm to solve related problems.

[0052] First, we acquire the image and enlarge the image: for 4 exposures, the width and height of the image will be enlarged by 2 times; for 9 exposures, the image width and height will be enlarged by 3 times; and so on.

[0053] Then, we sequentially display the separated small images on the screen for exposure, and move the LCD screen slightly with each exposure, so that the landing points of multiple exposures of the same pixel on the LCD screen are evenly filled on the screen In the horizontal and vertical grids generated by pixel spacing, we not only increase the number of exposed pixels, but also su...

Abstract

A method for processing display-exposure of high resolution LCD screen on digital color amplifier includes amplifying obtained image as using four times of exposure to amplify size of image to be two times and using nine times of exposure to amplify it to be tree times, dividing amplified image to be 4 or 9 pieces of image and displaying divided small image on screen in sequence, coordinating each exposure by moving LCD screen to a direction for making the same pixel point on LCD screen be filled into lattice on screen rightly and uniformly so as to raise quality of photo.

Description

technical field [0001] The invention relates to a display exposure method using a high-resolution LCD display screen for a digital color printing machine, in particular to a display exposure method using a QXGA-level LCD display screen. Background technique [0002] Conventional XGA-level LCD screens have a resolution of 1280×1024 or 1600×1200 and a small imaging area, while QXGA-level LCD screens have a resolution above 1600×1200 and a relatively large imaging area. The improvement of the resolution makes the quality of the printed photos have to be improved accordingly. At the same time, the use of a large LCD screen can reduce the magnification of the lens, reduce the negative impact of high magnification of the lens, or print larger and more photos, and further use the screen-shifting interpolation algorithm to improve the exposure effect. [0003] Since there is currently no chip that can fully drive a QXGA-level LCD. Therefore, all major manufacturers use dual-chip d...
