Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, PROGRAM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/020358
Kind Code:
A1
Abstract:
This image processing device is characterized by comprising: an input means for inputting a distance information distribution calculated from an image captured using optics focusing a field image on an image capture element of an image capture means; an estimating means for estimating a depth direction in the image from a photographing condition of the image capture means; and a determination means for determining an evaluation value indicating a degree of deviation of the optics and the image capture element from design positions, on the basis of a relationship between the distance information distribution and the estimated depth direction.
