ABSTRACT:
An endoscope comprises an elongated inserting section having an illumination window and an observation window at a distal end portion thereof, an imaging device for forming an optical image of an object upon receiving light reflected from the object radiated through the observation window, and an ultrasonic probe disposed at the distal end portion of the inserting section and adapted to obtain an ultrasonic image of the object. A signal processing apparatus to which the endoscope is connected comprises: an optical-image signal processing device adapted to effect signal processing for the imaging device and to generate a video signal of the optical image and having an optical image memory device for storing the optical image, an ultrasonic-image signal processing device adapted to effect signal processing for the ultrasonic probe and to generate a video signal of the ultrasonic image and having an ultrasonic image memory device for storing the ultrasonic image, and a memory device control device which is adapted to control writing and reading by the optical image memory device and the ultrasonic image memory device, and which, when a moving ultrasonic image is viewed, makes it possible to display a still optical image, and, when a moving optical image is viewed, makes it possible to display a still ultrasonic image.
