Patent ID: 7916350

Claim:
A method for minimizing visual artifacts generated from laser scan process directional errors in an image reproduction device, the method comprising: scanning an image having a plurality of halftone cells arranged in a brick-layer structure; determining an error profile applicable to said scanned image; based on said error profile, determining a start pixel location along a start border of a first halftone cell; defining a first line pattern traversing through said first halftone cell in a process direction, said first line pattern beginning at said start pixel location and defining a first number of steps in a first direction towards a center of said first halftone cell and defining a second number of steps in a second direction towards an end pixel location at an end border of said first halftone cell opposite to said start pixel location at said start border, such that said first number of steps in said first direction equals said second number of steps in said second direction, each step in said first line pattern defining a start location of a pixel shift operation to correct said error; and for each scanline of said first halftone cell, shifting a pixel segment along said scanline in a direction defined by said error profile starting from said first line pattern.
