Title: Screening method
Inventor: MIYAGI MAKOTO
IPC: H04N1/52
Filed: 2003-06-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a screening method capable of increasing variations of a halftone screen.  <P>SOLUTION: Halftone cells 1 with a special shape obtained by arranging 10 pixels (dots) 2 as illustrated is used to prepare a tile 3 by spreading the halftone cells. A distance to an adjacent cell determines the area of a cell 1 regardless of the shape of the cell 1, and the area of the cell 1 becomes equal to the number of gradations. Even when a cell of a special shape is very large, the number of gradations can easily be calculated. Also, a dither suitable for a Letraset type dither can be created, and in addition, a high quality halftone cell can be created by performing cell arrangement and dot growth so as to suppress pattern generation.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
