<P>PROBLEM TO BE SOLVED: To enhance the precision of searching based on correlation calculation between the image data of supersonic waves. <P>SOLUTION: The image data of the ultrasonic waves of a plurality of time phases are stored in an image storing section 22. A pattern matching processing section 30 has a function generating a template corresponding to a set point based on the set point set in the image data of a reference time phase, a function setting the searching area in the image data in a searching time phase, a function executing the correlation calculation based on the image data of the template of the reference time phase and the image data overlapping the template of the searching time phase in the respective positions in the searching area while moving the template in the searching area, and a function weighting the result of the correlation calculation obtained in the respective positions according to the distance from the reference position to the respective positions in the searching area. The moving point corresponding to the set point is searched in the searching area based on the weighted result of the correlation calculation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
