Abstract
A droplet discharge apparatus to discharge droplets while moved by a user includes a head to discharge a droplet onto a recording medium, a sensor to detect a movement amount of the droplet discharge apparatus in a predetermined period, and a memory to store determination information indicating whether droplet discharging has been instructed for each pixel of the image data. The droplet discharge apparatus further includes a processor configured to accumulate the movement amount to calculate a total movement amount of the droplet discharge apparatus; instruct droplet discharging from the head based on the total movement amount and the image data; instruct droplet discharging only for an unprinted pixel for which the determination information indicates that droplet discharging has not been instructed; and rewrite the determination information of the unprinted pixel to indicate that droplet discharging has been instructed, based on a predetermined condition.
