ABSTRACT:
A liquid ejecting device includes an ejection pattern storage unit and a read-address shifting unit. In the ejection pattern storage unit, ejection patterns corresponding to grayscale data items, each data item representing a grayscale by using the number of droplets to be delivered to pixel regions, are stored so as to be associated with the pixel regions. In each ejection period of droplets, the read-address shifting unit shifts read addresses to be supplied to the ejection pattern storage unit in response to the deflecting direction of each of ejecting outlets.
