1. A display control apparatus, comprising:
an input unit configured to be operated to change a display state of a plurality of content items displayed on a display screen; a circling detector configured to detect whether or not a user operation is a circling operation from a trail from a start point to an end point of a user operation with respect to the input unit such that an arbitrary position on the display screen is enclosed, such that if the detection result indicates a circling operation, the circling detector detects whether a circling direction is a first direction or a second direction which is opposite to the first direction and detects a number of revolutions in the circling operation, and also determines the area on the display screen enclosed by the trail to be a selection area; a content item search unit configured to search the plurality of content items for relevant content items that correspond to position information included inside the selection area; and a content display quantity adjuster configured to display or hide the relevant content items according to the circling direction, and in the case of a plurality of relevant content items, determine the number of relevant content items to display or hide from among the relevant content items on the basis of the number of revolutions, such that when the circling direction is detected to be the first direction the determined number of relevant content items are displayed and when the circling direction is detected to be the second direction the determined number of relevant content items are hidden.
