Claim:
1. A liquid ejecting control method for ejecting liquids from a plurality of nozzles comprising: a step for obtaining control information indicating one drive mode to be associated among a plurality of drive modes in which an amount of liquids ejected from one nozzle is different from each other; and a drive signal generating step for generating a drive signal to an individual pixel according to the control information and image data that is input for each pixel, wherein the control information is preliminarily set according to a control information setting method including: a step for obtaining a plurality of ejection amounts corresponding to the plurality of drive modes in regard to each of the plurality of nozzles; a setting step for, in regard to one pixel, setting one drive mode out of the plurality of drive modes by comparing the plurality of ejection amounts of the nozzle corresponding to the pixel with a target ejection amount set to the pixel; a difference obtaining step for finding a difference between an ejection amount corresponding to the drive mode set by the setting step and the target ejection amount; and an adjusting step for adjusting a target ejection amount to the other pixel to which the drive mode is not set, based upon the difference.
