IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD

摘要

An image processing apparatus that outputs a high-quality image having excellent robustness and reduced graininess by using a multi-pass printing method that performs printing in pixel areas of a printing medium based on a plurality of multi-valued image data that correspond to a plurality of relative movements. To accomplish this, the image processing apparatus executes quantization processing of second multi-valued image data that corresponds to a second relative movement of a plurality of relative movements based on first multi-valued image data that corresponds to a first relative movement of the plurality of relative movements, and executes quantization processing of the first multi-valued image data based on the second multi-valued image data. This makes it possible to output a high-quality image having excellent robustness and reduced graininess by controlling the overlap rate of dots that are printed by the first relative movement and the dots that are printed by the second relative movement.
