1. An input apparatus comprising: an input unit for accepting an input; a display unit for displaying an input result to the input unit; an input mode determination unit for determining whether the input to the input unit is a first input mode or a second input mode; and an input control unit for controlling, when the input to a key of the input unit is determined as the first input mode by the input mode determination unit, so that a plurality of characters assigned to the key are sequentially changed and displayed on the display unit as input character candidates in response to the input, and when the input to the key of the input unit is determined as the second input mode by the input mode determination unit, for searching a previously inputted character string to find characters corresponding to the characters assigned to the key among the previously inputted character string, wherein the characters found by the searching are displayed on the display unit as correction character candidates, and controlling movement of a cursor displayed on the display unit to the correction character candidates searched for in response to the input.
