An input control device includes a detection unit configured to detect a first character input by a key operation. The input control device also includes a determination unit configured to determine whether or not the detected first character is the same as a second character input immediately before the first character, and an input processing unit configured to accept an input of the first character when it is determined that the first character is not the same as the second character without accepting the input of the first character when it is determined that the first character is the same as the second character.
