Image processing methods, programs, ophthalmic devices, and choroidal blood vessel image generation methods

摘要

Reduces retinal vessels from affecting the analysis of choroidal vessels. The image data of the first fundus image (R color fundus image) and the second fundus image (G color fundus image) are read out, the retinal blood vessels are extracted from the second fundus image, and the retinal blood vessels are removed from the first fundus image. The choroidal blood vessels are emphasized in the first fundus image in which the choroidal blood vessels are relatively conspicuous. As a result, a choroidal blood vessel image in which the choroidal blood vessel is emphasized can be obtained.
