ABSTRACT:
In a droplet ejecting apparatus, a detection pattern output unit drives a droplet ejecting head based on a pulse signal and image information of a detection pattern comprising plural unit patterns so as to form an image of the detection pattern on a recording medium. A correction information generating unit derives a distance between adjacent unit patterns based on the image of a read detection pattern, compares the distance with a distance according to the conveyance velocity of the recording medium by a moving unit, and generates correction information so as to enlarge the pulse width when the derived distance is shorter, and to reduce the pulse width when the derived distance is longer.
