Abstract: An ultrasonic sensor device includes a plurality of pixels each including an ultrasonic transducer, and a control circuit configured to control the plurality of pixels. Each of the plurality of pixels is configured to hold a signal received by the ultrasonic transducer therein and send the signal to the control circuit as a response signal. The control circuit is configured to acquire an excitation response signal, which is a response signal sent from a pixel after the ultrasonic transducer therein is excited, acquire a non-excitation response signal, which is a response signal sent from a pixel when the ultrasonic transducer therein is not excited, and correct the excitation response signal based on the non-excitation response signal.
