Abstract

A display control device includes a display control unit and an input unit. The display control unit is configured to display, on a display screen, a first selection area displaying a list of a plurality of first data items, a first scroll bar corresponding to the first selection area, a second selection area displaying a list of a plurality of second data items, and a second scroll bar corresponding to the second selection area. The input unit is configured to receive a selection operation for selecting at least one item from the first data items displayed in the list in the first selection area. In conjunction with the selection operation of the first data item, the display control unit changes the second data items displayed in the list in the second selection area and the display mode of the second scroll bar.

11. The display control method according to claim 10, wherein the size of the second scroll bar increases within the second scroll area in response to the number of the second data items displayed in the list in the second selection area decreasing, and the size of the second scroll bar decreases within the second scroll area in response to the number of the second data items displayed in the list in the second selection area increasing.

12. The display control method according to claim 10, further comprising:

changing the size of the first scroll bar to cover a greater or lesser portion of the first scroll area in accordance with an opposite change in the number of the first data items displayed in the list in the first selection area.

13. The display control device according to claim 12, wherein the size of the first scroll bar increases within the first scroll area in response to the number of the first data items displayed in the list in the first selection area decreasing, and the size of the first scroll bar decreases within the first scroll area in response to the number of the first data items displayed in the list in the first selection area increasing.
