An image display apparatus according to an embodiment of the present technology includes a display control unit and a processing executing unit. The display control unit controls display of a designation image capable of designating a region with respect to a target image. The processing executing unit executes processing associated with the designation image on a designated region designated by the designation image. The processing executing unit executes, on an overlap region in which a first designated region designated by a first designation image and a second designated region designated by a second designation image overlap with each other, first processing associated with the first designation image and second processing associated with the second designation image. The display control unit moves the second designation image in conjunction with movement of the first designation image when the overlap region exists.
