Abstract
In an ultrasonic microscope apparatus, an ultrasonic pulse transmitter-receiver emits an ultrasonic wave irradiated on a sample, receives an echo from the sample, and emits an electric output signal in accordance with the received echo. A scanner is provided for scanning the sample by relatively moving the ultrasonic pulse transmitter/receiver and the sample, and, a detection circuit is provided for detecting an echo component included in the output signal from the ultrasonic pulse transmitter-receiver and for emitting a detected signal. A picture quality adjuster receives the detected signal, adjusts brightness and contrast of the detected signal, and outputs the adjusted signal as an image signal. An adjustment controller adjusts the adjustment amount of brightness and contrast in the picture quality adjuster in accordance with the brightness and contrast values of the image signal output from the picture quality adjuster.
