IPC: H04N1/405
Filed: 2004-02-27
Abstract: <P>PROBLEM TO BE SOLVED: To suppress the occurrence of a dot delay in an image processor for executing binarization processing by using an average error minimization method.  <P>SOLUTION: A weighting error sum e[i, j] is calculated on the basis of the average error minimization method (S320) and a threshold (th) is determined (S330) in the printer device. Concretely, the larger the variable I value, the smaller the threshold (th) (a larger minus value) is set. When e[i, j] is less than the threshold (th), a value of eO for correcting the value of the variable I is changed from eO=e[i, j] to eO=th (S345). A density value Ic is obtained by adding the eO to the variable I (S350) in the printer device. Therefore, when e[i, j] becomes an excessively larger minus value, the density value Ic takes a value larger than the density value Ic=I+e[i, j] during normal time. Dot output is turned on when the density value Ic exceeds a reference value (thre) (S363) in the printer device.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
