Control is made in such that in a case where an attitude detected by an attitude detection unit is a first attitude, if a trace of a detected touched position satisfies a specific condition, a function corresponding to the detected trace is executed, and in a case where the detected attitude is a second attitude opposite to the first attitude, even if the trace of the detected touched position is a trace which satisfies the specific condition, the corresponding function is not executed. Thus, when an electronic apparatus is upside-down, a specific gesture operation by a touch operation is invalidated.
