Abstract

A liquid droplet discharging apparatus includes a plurality of nozzles to discharge a liquid droplet onto a medium and a liquid droplet discharging controller to receive image data. The liquid droplet discharging controller controls each of the nozzles to discharge the liquid droplet in an amount defined by the image data onto a target discharging position on the medium, which corresponds to a pixel position defined by the image data. The liquid droplet discharging controller controls at least one of the nozzles to discharge the liquid droplet for a controlled number of times smaller than a number of times N representing an integer not smaller than 2 in an amount greater than the amount defined by the image data onto the target discharging position on the medium. A frequency recorder records the controlled number of times of discharging for each of the at least one of the nozzles.
