Title:
METHOD FOR BREAKING SYMMETRY OF MATRIX ELEMENT IN ELECTRONIC HALF-TONE SCREENING METHOD
Document Type and Number:
Japanese Patent JPH05110836
Kind Code:
A
Abstract:
PURPOSE: To destroy the symmetry of matrix elements by adding an irrational number to XY coordinates of the matrix elements. CONSTITUTION: An X coordinate and a Y coordinate are respectively decided for each XY coordinate element in at least one matrix for a screen function period. A same or a different irrational number is added to the X coordinate and the Y coordinate in pairs. Thus, the symmetry of the matrix elements is destroyed.
