Abstract
A tire inspection device generates an analyzing wavelet for wavelet transformation correlating time, corresponding to tire surface position, and frequency, based on a frequency representing a characteristic portion of a predetermined tire surface structure. After this, the tire inspection device generates and stores an integer numeric filter from the created analyzing wavelet, detects the tire surface structure, carries out wavelet transformation on a signal obtained by the detection by using the numeric filter as the analyzing wavelet, and outputs the transformation result as the characteristic information representing the characteristic portion.
