Distortion estimating image processing device, method, and non-transitory storage medium

摘要

An image processing device includes an image input portion, a motion vector acquisition portion and a distortion component estimation portion. The image input portion inputs a target image which is an image to be processed. The motion vector acquisition portion acquires a motion vector generated by relative movement with respect to a subject drawn in the target image when an imaging device which has generated the target image generates the target image. The distortion component estimation portion estimates a rolling shutter distortion component of the target image based on the motion vector.

1. An image processing device that processes an image, comprising:
an image input portion inputting a target image that is an image to be processed; a motion vector acquisition portion acquiring a motion vector generated by relative movement with respect to a subject drawn in the target image when an imaging device generates the target image; and a distortion component estimation portion estimating a rolling shutter distortion component associating a coordinate system of the target image without distortion with a coordinate system of the target image with distortion based on a parallel movement component the motion vector and a distortion coefficient.
