Patent number: 5615021Abstract: Generating a N-tone image relatively inexpensively with substantially imperceptible dots. The method generates the N-tone image from a grey scale image, both images have many pixels, with each pixel in the grey scale image having a grey level that is within a maximum and a minimum level, and with each pixel in the N-tone image having a level that is one of N levels with N bigger than two and less than the number of levels available for the grey scale image. The method includes the steps of determining the level of each pixel in the N-tone image based on the levels of its corresponding pixel in the grey scale image, and based on either an original dither matrix or an error diffusion technique. Each pixel is modelled by a number of sub-pixels, and each sub-pixel is modelled by a number of segments. Each segment has an intensity whose value depends on its corresponding pixel. The different intensities of the segments when combined together generate N substantially reproducible levels for the N-tone image.Type: GrantFiled: June 2, 1995Date of Patent: March 25, 1997Assignee: Hewlett-Packard CompanyInventor: Qian Lin
