摘要： There are provided a medium data display device, a medium data display method, and a medium data display program for displaying multi-medium data consisting of a plurality of media including a moving picture on a display screen by various display methods. The medium data display device (85) is a device for displaying multi-medium data consisting of a plurality of media including a moving picture on a display screen and includes a scaling judgment section (87), a scaling section (89), and a display section (19). The scaling judgment section (87) judges whether to modify the image size of the moving picture when displaying it or display it without modifying the image size. The scaling section (89) and the display section (19) are means for displaying the multi-medium data and perform display by switching whether to perform scaling according to the judgment result of the scaling judgment section (87).
