An image analysis apparatus includes: a distribution data generator that generates, on the basis of a sample image obtained by irradiating a biological tissue with light having an infrared bandwidth, distribution data indicating a distribution of light intensity in the infrared bandwidth in the tissue; a differential calculator that calculates, on the basis of the distribution data, an Nth-order derivative of the distribution of the light intensity in a first wavelength band in the infrared bandwidth, where N is an integer of 2 or more, for each region in the sample image; and an image data generator that converts the Nth-order derivative into a gray-scale value to generate image data.

An imaging method includes: irradiating breast tissue with infrared light, detecting light in a narrow wavelength band selected from wavelength bands from 1400 nm or more to 1600 nm or less, among light radiated from the tissue irradiated with the infrared light, and generating, based on the detected light in the narrow wavelength band, an image to specify an area in the tissue containing breast cancer cell aggregation or breast cancer tissue.

An image analysis apparatus includes: a calculator that generates, on the basis of a plurality of sample images obtained by irradiating a biological tissue with light having N wavelength bands selected from a wavelength bandwidth from 950 nm or more to 1600 nm or less as a predetermined wavelength bandwidth, sample data on the tissue in the predetermined wavelength bandwidth; and a data generator that compares the sample data with training data on a substance that is a training target, to generate distribution data indicating a distribution of the substance in the tissue.
