To provide an image displaying device, method and program, allowing a user to certainly and closely observe an interested image.

In this image display device, when a target image to be made to be displayed on a display is determined (S3), a browser that is a person present in a range wherein the display can be viewed is detected (S5). When a face feature of the browser is included in the target image, it is set such that a browsing time becomes long (S7). When the target image is changeover-displayed on the display (S9), a view line of the browser is detected (S17). When the target image is closely observed (S19: YES), a closely observing time of the browser is calculated (S25). When the closely observing time is the browsing time or longer (S27: YES), a next display image is changeover-displayed on the display (S9).
