When it is necessary to diffuse errors in a wide range such as in the highlighted region or the shadowed region, use of a matrix which diffuses errors isotropically may cause a reduction in the size of errors to be diffused in each pixel and dots may be generated closely. By diffusing errors while switching a plurality of matrices including a matrix having high directivity can avoid the dots from being generated closely.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
