1. A liquid ejecting apparatus, comprising:
a liquid ejecting head in which a plurality of nozzles for ejecting a liquid as droplets are arranged;
a first acquisition unit that acquires position information about positions of droplets ejected from the plurality of nozzles and traveling in air; and
a second acquisition unit that acquires, based on the position information, deviation information about a deviation in droplet landing position from a reference position on a reference plane, for droplets ejected from at least two nozzles among the plurality of nozzles; wherein
the position information includes first position information about a position, at a first timing, of a droplet ejected from a first nozzle, which is one of the plurality of nozzles, and traveling in air, and second position information about a position, at the first timing, of a droplet ejected from a second nozzle, which is one of the plurality of nozzles N and is different from the first nozzle, and traveling in air.
