Abstract: A display control apparatus, method and computer program storage device detect when an object is in a proximity position relative to a display. In response, a display state of a displayed item is changed. Then, a processing circuit causes a relation item to be displayed adjacent to the proximity position, the relation item being related to the displayed item. The displayed state may be changed in size, position, color and other ways to reflect the recognition of the object being detected as being proximate to a predetermined proximity location.
