According to one embodiment, an ultrasonic diagnostic apparatus includes detection circuitry and processing circuitry. The detection circuitry detects a release state of an ultrasonic probe in an active state. The processing circuitry, when the detection circuitry detects the release state of the ultrasonic probe during activation of a control mode of generating a first image based on an output from the ultrasonic probe, displaying a second image different from the first image, and displaying the first image with a predetermined opacity on the second image, perform one of control to display the second image without generating the first image, control to display the second image without displaying the first image while generating the first image, and control to generate the first image, display the second image, and display, on the second image, the first image with an opacity lower than the predetermined opacity.
