3. A character input device, comprising: a display unit; a touch sensor for detecting a contact with a surface thereof; a character recognition processing unit for performing a first character recognition process for recognizing a character used for a first function and a second character recognition process for recognizing a character used for a second function, on the basis of a locus connecting positions where the contact is detected by the touch sensor; and an input control unit for displaying, on the display unit, a first input screen for the first function onto which the character recognized by the first character recognition process is input and/or a second input screen for the second function onto which the character recognized by the second character recognition process is input, wherein the input control unit is configured to display the first input screen and/or the second input screen on the display unit, on the basis of a recognition accuracy of the character by the first character recognition process and a recognition accuracy of the character by the second character recognition process.
