4. The information processing apparatus according to claim 1, wherein the control unit is configured to perform control, if the information processing apparatus is in a specific mode, if a touchup operation has been detected by the touch detection unit in a state in which touching in the first area is detected, and if the time period counted by the time counting unit has reached the predetermined time period, not to execute the first function assigned to the first area in relation only to the detected touch-up operation while if the information processing apparatus is in a mode other than the specific mode and if a touch-up operation has been detected by the touch detection unit in a state in which touching in the first area is detected, to execute the first function assigned to the first area regardless of the time period of the continuous touching in the first area.

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

an imaging unit; and

a mode shifting unit configured to shift an operation mode of the information processing apparatus to one mode among a plurality of modes at least including an image shooting mode and an image reproduction mode, wherein the specific mode is the image shooting mode.

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

an imaging unit; and

a shutter operation member configured to receive a user instruction for taking an image given by the imaging unit,

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

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

a imaging unit; and

a shutter operation member configured to receive a user instruction for taking an image given by the imaging unit,

wherein the first 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 the closest from the shutter operation member than a position of the second area.

9. The information processing apparatus according to claim 1, further comprising a display control unit configured, if the time period counted by the time counting unit has reached the predetermined time period, to perform control to display a first warning message indicating that the first area has been touched on the display unit.

10. The information processing apparatus according to claim 9, further comprising a multi-point touching determination unit configured to determine whether an area other than the first area has been touched simultaneously with touching in the first area,

wherein the display control unit is configured, if it is determined by the multi-point touching determination unit that the area other than the first area has been touched simultaneously with touching in the first area, to display a second warning message indicating that an operation instructed by the touching cannot be executed on the display unit.

11. The information processing apparatus according to claim 10, wherein the touching detection unit can detect touching at a single touching position on the display unit only, and

the multi-point touching determination unit is configured, if touching on the display unit within a predetermined range in the display unit is detected without detecting a touch-up operation after touching in the first area is detected, to determine that the position included in an area other than the first area has been touched simultaneously with the touching in the first area.

12. The information processing apparatus according to claim 11,
