Laser print apparatus that generates pulse width value and justification value based on pixels in a multi-bit image
TLDR
In this article, a modulation code generator analyzes three adjacent pixels, including a left pixel, a center pixel, and a right pixel, to generate a pulse width value based on the value of the center pixel.Abstract:
A laser print apparatus includes a memory for storing a multi-bit image including a plurality of pixels. Each pixel is represented by an N-bit value, wherein N is greater than one. A modulation code generator analyzes three adjacent pixels. The three adjacent pixels include a left pixel, a center pixel, and a right pixel. The modulation code generator is configured to generate a pulse width value based on the value of the center pixel, and a justification value based on the values of the left pixel and the right pixel. A laser print engine forms an output pixel on media based on the pulse width value and the justification value.read more

System and method for enhancing graphic features produced by marking engines
TL;DR: In this article, a pixel in the array is analyzed in a transformation (window) to determine the pulse pattern output based on the gray level value of the current pixel and on the grey level values of adjacent vertical (44, 52) and horizontal pixels (46, 50).

Digital halftone rendering of a gray scale image with frequency-dependent diagonal correlation
TL;DR: In this paper, a method of halftoning a digital gray scale image is disclosed that utilizes a point-by-point thresholding comparison to a novel diagonal correlation dither matrix, which forces diagonal correlation of adjacent dots in the output image while maximizing dispersion of dots, thereby producing visually unobtrusive output dot patterns.
