Claim of US Patent No. 10,986,980

1. An image processing device that measures a blood vessel depth of a blood vessel in an observation target, the image processing device comprising:a memory storing a data set including a plurality of blood vessel index value variation factors and a plurality of blood vessel index values respectively associated with the plurality of blood vessel index value variation factors, wherein the plurality of blood vessel index value variation factors include the blood vessel depth; and
a processor, configured to:
acquire an image obtained by imaging the observation target;
calculate a blood vessel index value from a blood vessel index value image in the acquired image, wherein the blood vessels index value image comprises multiple-wavelength images;
select a specific blood vessel index value variation factor other than the blood vessel depth among the plurality of blood vessel index value variation factors in the acquired image; and
select a sub-data set having the specific blood vessel index value variation factor from the data set and obtain a blood vessel depth corresponding to the blood vessel index value according to the sub-data set.
