There are provided an image display device, an image display method, and a program capable of accurately evaluating omission in imaging. A computer (22) that executes an image display method according to a program includes: a storage unit (53) that stores an endoscopic image of an imaging target organ; a connection relationship setting unit (60) that sets a connection relationship between a plurality of endoscopic images (S4); a landmark image detection unit (61) that detects a landmark image including an anatomical landmark corresponding to the imaging target organ among the plurality of endoscopic images (S6); a mapping unit (62) that assigns the landmark image to a landmark portion of a virtual model corresponding to the imaging target organ (S8) and assigns the plurality of endoscopic images to corresponding portions of the virtual model using the connection relationship set with the landmark image as a base point (S10); a map image generation unit (63) that generates a map image, which shows an imaged region and a non-imaged region of the imaging target organ, based on the virtual model in which the plurality of endoscopic images are assigned to respective portions (S12); and a display control unit (64) that displays the map image on a monitor (S13).
