IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD

摘要

Provided is an image processing apparatus to easily identify an image acquiring position of an image by an adaptive optics SLO. The image processing apparatus analyzes an image of an eye to be inspected shot by an adaptive optics SLO, and includes a frequency conversion portion to frequency-convert the image to acquire a frequency spatial image; a characteristic extracting portion to extract a characteristic amount from the frequency spatial image, the characteristic amount relating to a ring-structure reflecting arrangement of photoreceptor cells; and a position estimating portion to estimate an image acquiring position of the image based on the characteristic amount.

主权项

1. An image processing apparatus that processes an image of photoreceptor cells at a fundus of an eye to be inspected, comprising:
a conversion unit to convert the image of the photoreceptor cells into an image indicating periodicity of the photoreceptor cells of the fundus; a characteristic amount acquiring unit to acquire a characteristic amount for the photoreceptor cells based on the image indicating the periodicity; and an estimating unit to estimate, based on the characteristic amount, a position where the image of the photoreceptor cells is acquired at the fundus.
