Abstract: [Problem] To provide an educational toy which allows an observed action to be experienced artificially. [Solution] A toy system (900) is used by bringing a magnifying-glass type hand-held instrument (930) into contact with a page (912) of a main body portion (910) having a picture portion (914). The magnifying-glass type hand-held instrument (930) captures an image of the picture portion (914), and determines the location, within the image in said picture portion, that has been captured. From pre-stored image data of a picture image that is the same as the picture portion (914), image data for a part (a partial image) corresponding to the location being captured are then read out and are displayed on a touch panel (942). If the location being captured fulfills certain location conditions, one image element from image elements W41 to W49 is also selected as a special image and is displayed superimposed on the partial image.
