Input control apparatus and input accepting method

A main control unit accepts an operation of deciding a touched button when the user releases the button on a touch panel in a menu window within a predetermined time period after touching the button without moving his/her finger along the touch panel. Also, the main control unit accepts an operation of deciding a touched button when the user keeps the button touched for more than the predetermined time period after touching the button without performing finger movement. When the user moves his/her finger along the touch panel to another position after touching a button without releasing the button in the predetermined time period, the main control unit does not accept a button deciding operation by release or long touch thereafter.
