Abstract
An apparatus includes a unit that analyzes frequencies of an ultrasonic wave at a plurality of points to calculate a frequency spectrum of the points; a unit that approximates a portion included in a frequency band between a first frequency and a second frequency larger than the first frequency, by a polynomial, in the frequency spectrum of the points to extract first spectrum intensity which is a value of the polynomial in a third frequency included in a domain of the polynomial and second spectrum intensity which is a value of the polynomial in a fourth frequency different from the first to third frequencies, as a feature amount; and a unit that associates the first spectrum intensity, the second spectrum intensity, and/or a function of difference or ratio between the first and second spectrum intensity, to generate a feature amount image to indicate a distribution of the feature amount.
