It is made possible to cancel the effect of the already executed command without performing burdensome operation if an unobjective command is executed for input operation of the user. An input signal analysis section 200 gives a command of execution of a first command corresponding to detection of input operation to a first operation button based on an input position of a touch panel 10 detected by an input signal control section 300 and if input operation to a second operation button is detected, gives a command of a second command corresponding to detection. If continuous input operation to the second operation button is detected after the first command corresponding to the first operation button is executed, and command change notification from the input signal analysis section 200 is received, an application 100 cancels the effect of the immediately preceding executed first command and executes the second command.
