When a tracking point and a tracking line are set in the images in the image display area Ta, a tracking operation is executed on each frame image to identify the position of the set tracking point on the set tracking line. A tracking result time change line indicating time changes in the position of the tracking point identified by the tracking operation on the plurality of frame images is displayed in an image display area Tb on the display section 20. When a time axis position of the tracking result time change line displayed in the image display area Tb is specified with a current display position bar L, the frame image corresponding to the specified position is displayed in the image display area Ta.
