Image processing device, imaging device, and image processing method

摘要

The present invention includes an image acquisition device configured to acquiring multiple viewpoint images that are generated by pupil-division imaging and that are different in viewpoint, a parallax calculation device 40a for calculating a first parallax amount between viewpoint images for the multiple viewpoint images, a memory 48 in which parallax correction information indicating the relationship between the first parallax amount and the deviation amount in the parallax direction for the corresponding object images, which is a deviation amount between viewpoint images for the multiple viewpoint images and is caused by the pupil-division imaging, is stored, and a parallax correction device 40b for calculating a second parallax amount, which is an amount resulting from correcting the first parallax amount to the deviation amount in the parallax direction for the object images, based on the first parallax amount and the parallax correction information stored in the memory 48.

1. An image processing device comprising:
an image acquisition device configured to acquiring multiple viewpoint images generated by pupil-division imaging, the multiple viewpoint images being different in viewpoint; a first parallax amount calculation device configured to calculating a first parallax amount between viewpoint images for the multiple viewpoint images; a storage device in which parallax correction information is stored, the parallax correction information indicating a relationship between the first parallax amount and a deviation amount in a parallax direction for corresponding object images, the deviation amount being a deviation amount between viewpoint images for the multiple viewpoint images and being caused by the pupil-division imaging; and a second parallax amount calculation device configured to calculating a second parallax amount based on the first parallax amount and the parallax correction information stored in the storage device, the second parallax amount being an amount resulting from correcting the first parallax amount to the deviation amount in the parallax direction for the object images.
