发明名称 Image processing apparatus and method for converting multivalue image data into multivalue image data corresponding to relative movements
摘要 An image processing apparatus and an image processing method are provided which, when forming an image using a plurality of different sizes of dots, can produce a satisfactory image free from problematical levels of density unevenness, graininess and insufficient density with any of these dot sizes. To this end, when printing on pixel areas of a print medium by a plurality of relative movements between the printing unit and the print medium, the dot overlap rate of a dot size that tends to show density unevenness is set higher than that of a dot size that tends to show other image impairments more conspicuously than the density unevenness. This results in a satisfactory image that eliminates such image impairments as density unevenness, graininess and density insufficiency in the entire grayscale range.
