Abstract
An image signal processing circuit for an ultrasonic imaging apparatus includes a frame correlation circuit for performing, in accordance with a predetermined correlation coefficient, a frame correlation process for an ultrasonic frame image signal output from an ultrasonic transmitter/receiver circuit, and a correlation coefficient output circuit for outputting a frame correlation coefficient corresponding to a difference between a current input frame image signal and an immediately preceding frame image signal, i.e., a coefficient which decreases as the difference increases to the frame correlation circuit.
