In a viewer which acquires an image in a depth position from three-dimensional image data and displays the image, a three-dimensional position specification method for specifying three-dimensional positions in the X, Y and Z directions using a pointing device capable of performing two-dimensional moving operation of a position in the X and Y directions is executed. In the viewer, a position in the X direction on the display image is specified by moving the pointing device in the X direction; a position in the Y direction on the display image is specified by moving the pointing device in the Y direction; and a position in the depth direction of the display image is specified by moving the pointing device in a diagonal direction.
