Title: Image forming apparatus and method therefor
Inventor: UCHIYAMA AKIHIKO
IPC: H04N1/405
Filed: 2003-02-12
Abstract: <P>PROBLEM TO BE SOLVED: To eliminate graininess caused by superposition of noise of image data.  <P>SOLUTION: In generating the image data, a rasterizer 28 stores generated bit map data in an image memory, and records a region occupied by an image object such as a photograph image in an attribute map memory 30 so that it can be identified. An image processing unit 31 compares an average value of pixel values of the region of the image object and standard deviation with predetermined values, of the bit map data, to determine the presence of distribution of noise. For a region determined to contain noise, an image processing unit 32 performs quantization processing by using a dither matrix having a larger size than that of a region not containing noise to comparatively lower a resolution, thereby eliminating the graininess caused when forming an image in an engine unit B.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
