Abstract: It is an object of the present invention to provide an image processing apparatus, an endoscope system, an image processing method, an image processing program, and a recording medium capable of accurately estimating blood vessel information. An image processing apparatus according to an aspect of the present invention includes: an image acquisition unit that acquires an image of a living body; a blood vessel index value calculation unit that calculates a blood vessel index value of the living body from the acquired image; a blood vessel density calculation unit that calculates a blood vessel density of the living body from the acquired image; a blood vessel index value correction unit that corrects the calculated blood vessel index value according to the calculated blood vessel density; and a blood vessel information estimation unit that estimates blood vessel information of the living body based on the corrected blood vessel index value.
