Abstract

A display control unit (15) in an input display control device (1) displays an image including a symbol display area in which a symbol input by a user is displayed, on the screen of a display unit (11). The display control unit (15) also displays operation buttons and symbols allocated to the operation buttons on the screen of the display unit (11) while being superimposed on the image displayed by the display control unit (15), the operation buttons being arrayed in a virtual keyboard through which a symbol to be displayed in the symbol display area is input through tapping on the display unit (11), the operation buttons being translucently displayed. The display control unit (15) also changes a display color of the symbols allocated to the operation buttons arrayed in the virtual keyboard to a display color selected from a plurality of display colors set in advance.
