Summary:In the medical diagnostic apparatus employing line-of-sight detection, eye movement and head movement of a subject are detected by eye movement detecting portion (2) and head movement detecting portion (3), respectively, and images of the field of view of the subject are picked up by a TV camera (6). A calculating portion (1) calculates a locus of the line-of-sight, a locus of the eye movement, the locus of the head movement, and vectors of spatial movement of the line-of-sight in response to the detected eye movement and the head movement. An image processing portion (7) reduces the picked up image, a superimposer (4) superimposes the images of the loci, the vector images and the images of the reduced field of view on each other, and the resulting images are displayed on a CRT display (5).
