An image display apparatus 4 includes a control unit 15 having an image display controller 15a and an image processing controller 15b so that an imaging period where an image of interest is present can be recognized easily. The image display controller 15a displays a time bar 27 as a time scale indicating an imaging period of a series of intra-subject images； and a landmark button 29 as an appending unit that appends marker information indicating an image of interest to a main display image 23 displayed in a main display area 22. Further, the image display controller 15a controls, based on the imaging time point of the image of interest appended with the marker information, to display a display area before the imaging point or a display area after the imaging point on the time bar 27 so as to be discriminable from other display areas on the time bar 27. The image processing controller 15b obtains image data stored in a portable recording medium 5 or a storage unit 14, outputs the image data to an image processor 13, and controls various image processing for the output image.
