Abstract: There is provided a liquid ejecting control method for outputting an image without an influence of ejection amount variations. Therefore among a plurality of drive modes in which an amount of liquids ejected from one nozzle is different from each other, control information indicating a drive mode to be associated is obtained, and a drive signal to an individual pixel is generated according to the control information and image data that is input for each pixel. The control information sets a drive mode in which an ejection amount closer to a target ejection amount is obtained, among the plurality of drive modes. In addition, a difference between the target ejection amount and the ejection amount to be realized in the set drive mode is found, and this difference is used to correct a target ejection amount of the other pixel in which the drive mode is not set yet.
