Claim 20:
21. A control method of an acoustic wave device, the method comprising:
receiving an acoustic wave emitted from a tissue of a subject by irradiating an inside of the subject with an ultrasonic beam or laser beam to generate a tomographic image generating reception signal;
irradiating a photoacoustic wave generator of an insertion object with the laser beam, the insertion object being able to be inserted into the subject and having the photoacoustic wave generator at a distal end portion;
receiving a photoacoustic wave from the photoacoustic wave generator to generate an insertion object image generating reception signal;
generating an insertion object image signal representing an image of the distal end portion of the insertion object from the insertion object image generating reception signal,
generating a tomographic image signal representing a tomographic image of the subject from the tomographic image generating reception signal,
detecting a first signal width of the insertion object image signal having a signal strength of a predetermined ratio to a peak value of a signal strength in the insertion object image signal,
generating, in a case where the first signal width is larger than a predetermined second signal width, an insertion object display image signal having a center at a peak position where the signal strength of the insertion object image becomes the peak value and having a maximum width corresponding to the second signal width, from the insertion object image signal;
generating, in a case where the first signal width is smaller than the second signal width, an insertion object display image signal having a center at the peak position and having a maximum width smaller than the second signal width; and
superimposing a tomographic image of the subject and an image of the distal end portion of the insertion object to be displayed on a display on the basis of the tomographic image signal and the insertion object display image signal.
