Embodiment Construction

[0029] Below in conjunction with accompanying drawing, the present invention will be further described: a kind of frequency modulation hanging net method that carries out image duplication on the equipment of multi-bit imaging depth, comprises the following steps:

[0030] 1) input original image, carry out threshold value operation to the pixel g (m, n) of original image, the result of operation is converted into the corresponding pixel b (m, n) of halftone image;

[0031] The domain value when performing domain value operation is not fixed, and is not equally divided;

[0032] Moreover, when performing calculations, it is also necessary to perform random processing on the set threshold value. Every time the threshold value is used, a random number is added, and the range of the random number is [-8 8];

[0033] 2) compare b(m, n) with the thresholded pixel g(m, n), and obtain the difference between the two, that is, error e(m, n);

[0034] 3) Spread the error e(m, n) to the...

Abstract

The present invention relates to a kind of frequency modulating Internet access method for copying image on multiple position imaging depth equipment. On the basis of error diffusion frequency modulating Internet access, multiple threshold error diffusion technology is utilized to perform diffusion of different parameters for images of different layers and required image output data of the multiple position imaging depth equipment are outupt directly through combination to random disturbance. The said method can improve image quality greatly, make image layers transit smootly, make netted point distribution of different layers more homogeneous and high brightness part ever fine.

Description

technical field [0001] The invention relates to a network point generation method in the field of image hard copy reproduction, in particular to a network hanging method for image reproduction on equipment with multiple imaging depths. Background technique [0002] The hard copy reproduction of images mainly involves the hanging net plate-making technology of printers and high-end printing plate-making equipment. The hanging net technology used for hard copy reproduction of images is also called digital image halftone technology. Digital image halftone technology can be divided into two categories, namely amplitude modulation hanging net and frequency modulation hanging net. The amplitude modulation hanging net is also known as the gathering point orderly dithering technology, which is characterized in that the dyeing points of the generated halftone image are aggregated in pairs adjacent to each other in geometric positions, thus forming a cluster of dyed areas , These dy...
