For this purpose, when a pixel is printed by M relative scans of a print head over a print medium or by a relative scans of M print heads over the print medium, M pieces of multivalued image data is created according to a division number or distribution ratio determined by a grayscale value of that pixel. The M pieces of multivalued image data are individually quantized and then the printing is performed according to the quantized pixel data. This process prevents dot generation delays and graininess from deteriorating in highlighted areas, thus realizing printed images highly robust against density variations."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image processing apparatus and image processing method","description":"Graininess is suppressed while at the same time minimizing grayscale variations caused by inter-plane deviations.
