Abstract
An image recording apparatus includes: a plurality of recording heads driven on a basis of drive waveform data; a data storage that retains parameter sets corresponding to the respective recording heads; a simultaneously driven nozzle count detector that detects, for each of the recording heads, a simultaneously driven nozzle count that represents a count of nozzles to be driven at an identical drive timing based on image data to be recorded on a recording medium; a correction parameter selector that selects, for each of the recording heads, a correction parameter corresponding to the detected simultaneously driven nozzle count from among a plurality of correction parameters included in the parameter set corresponding to the recording head; and a drive waveform data generator that corrects reference waveform data using the correction parameter selected for each of the recording heads and generates the drive waveform data for each of the recording heads.
