Title: Production of threshold matrix and image processing method
Inventor: HIRAI SHINYA
IPC: G09G3/36
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To eliminate the pseudo outlines and stripes which are caused when a density pattern is applied via a threshold array and also to prevent the irregularity of scales of an output image regardless of the pixel positions set after the halftone processing by changing an array pattern into the elements of blocks obtained by dividing a threshold matrix into a prescribed size and then setting the threshold. SOLUTION: Every fixed pixel, for example, is selected from every block to decide a proper pixel and threshold 0 is given to this pixel. It is decided whether the threshold is given to all pixels of a matrix. In the case the threshold is given to all pixels, this processing is ended. When not, a proper fixed pixel is selected from every block and the value +1 is added to the selected pixel with respect to the threshold that is precedently given. It is decided again whether the threshold is given to all pixels and this processing is repeated until the threshold is given to all pixels. In this example, an input image has the 8-bit information per pixel.
