Abstract: A display control apparatus that is capable of making a user feel a fact that a user's operation is received and of notifying the user that an end of a scrolling range has come. A display unit displays a displaying object. An operation detection unit detects a user's operation to the display unit. A display control unit scrolls the displaying object when the operation detection unit detects an instructing operation of scrolling, and displays a shadow of the displaying object and moves the shadow in a direction opposite to a direction of scrolling by the instructing operation when the instructing operation is not completed even if the displaying object has been scrolled to an end of a scrolling range.
