5. The information processing apparatus according to claim 4, further comprising:

a shutter operation member configured to receive a user instruction for imaging by an imaging unit,

wherein the specific area is an area of a button icon displayed on the display unit at a position that is closer to a vertex of the display unit that is closest to the shutter operation member than a position of the area other than the specific area.

6. The information processing apparatus according to claim 1, further comprising:

a shutter operation member configured to receive a user instruction for imaging by an imaging unit,

wherein the specific area is an area of a button icon displayed on the display unit at a position that is closest to a vertex of the display unit that is closest to the shutter operation member.

7. The information processing apparatus according to claim 1, further comprising:

an attitude detection unit configured to detect an attitude of the information processing apparatus,

wherein a different position on the display unit is set as the specific area according to an attitude detected by the attitude detection unit.

8. The information processing apparatus according to claim 1, further comprising:

a second time counting unit configured to count a time period of continuous touching in a second area of the display unit which is different from the specific area,

wherein the control unit is configured to perform control, when a touch-up operation is detected by the touch-up detection unit in a state in which a touching operation for touching the second area has been detected by the touching detection unit, and if the time period of continuous touching counted by the second time counting unit has not reached a second time period which is longer than the predetermined time period, to execute a function assigned to the second area while when the touch-up operation is detected by the touch-up detection unit in a state in which the touching operation for touching the second area has been detected by the touching detection unit, and if the time period of continuous touching counted by the second time counting unit has reached the second time period, not to execute the function assigned to the second area in response to the detected touch-up operation.
