Abstract
An image processing device, an image processing system, and an image processing method capable of easily correcting image deterioration caused by nonuniform optical characteristics around an optical axis of a lens according to a position in a rotational direction of a lens barrel are provided. An image processing device includes a communication unit (42) that inputs a first image indicating a correction reference position in a rotation direction of a lens barrel (24) and a second image that is a correction target, the first image and the second image being obtained by imaging of the imaging device (10), a rotation position recognition unit (62) that recognizes the correction reference position in the rotational direction on the basis of the first image, a correction information acquisition unit (66) that acquires correction information on the basis of the correction reference position in the rotation direction, and an image correction unit (68) that corrects the second image on the basis of the correction information.
