发明名称 Image processing device and image processing method
摘要 An image processing device includes a binarization unit for converting a pixel value of image data into binary data, the pixel value showing a gradation value of a pixel, the image data including a plurality of pixels, the pixels being laid out as a matrix, the binary data showing a dot radius of a unit dot, the unit dot being laid out with lower resolution than the maximum print resolution at least in a direction of print media feeding direction; an expansion dot generation unit for generating print control data on the basis of the binary data obtained by the binarization unit, the print control data including data showing dot radii of a standard dot and an expansion dot, the standard dot being formed at a location, the location being determined on the basis of the unit dot, the expansion dot being formed at a different location to the standard dot; and an output unit for outputting to a image forming device the print control data generated by the expansion dot generation unit, the image forming device having a plurality of nozzles, the nozzle ejecting an ink dot; wherein a density of an image including the standard dot and the expansion dot is approximately equal to a density of an image including the unit dot.
