4. The non-transitory computer-readable storage medium storing the program as defined in claim 3 ,

wherein the input processing section accepts the position designation operation performed for the disturbance area as a second input operation; and

wherein the disturbance area setting section cancels the disturbance area based on the accepted second input operation.

5. The non-transitory computer-readable storage medium storing the program as defined in claim 3 ,

wherein the input processing section accepts the position designation operation performed for the disturbance area as a second input operation; and

wherein the disturbance area setting section moves the disturbance area based on the accepted second input operation.

6. The non-transitory computer-readable storage medium storing the program as defined in claim 3 , causing the computer to further function as:

a counter section which counts the passage of time,

wherein the disturbance area setting section cancels the disturbance area when a given period of time has elapsed.

7. The non-transitory computer-readable storage medium storing the program as defined in claim 1 , causing the computer to further function as:

an operation area setting section which moves the operation area when a given disturbance condition has been satisfied.

8. The non-transitory computer-readable storage medium storing the program as defined in claim 1 , causing the computer to further function as:

a communication control section which exchanges information with an external device,

wherein the communication control section transmits a disturbance setting command to another device based on a calculation result of the game calculation section; and

wherein the disturbance area setting section sets the disturbance area in the operation area based on the disturbance setting command received from the other device.

9. The non-transitory computer-readable storage medium storing the program as defined in claim 8 , causing the computer to further function as:

an event control section which controls generation of a disturbance event by which whether or not the disturbance condition has been satisfied is determined,

wherein the event control section prohibits generation of the disturbance event when the disturbance setting command has been transmitted to the other device.

10. The non-transitory computer-readable storage medium storing the program as defined in claim 8 , causing the computer to further function as:

an event control section which controls generation of a disturbance event by which whether or not the disturbance condition has been satisfied is determined,

wherein the communication control section transmits disturbance setting information to the other device when the disturbance area setting section has set the disturbance area; and

wherein the event control section prohibits generation of the disturbance event when the disturbance setting information from the other device has been received.

11. The non-transitory computer-readable storage medium storing the program as defined in claim 8 ,

wherein the communication control section transmits disturbance cancellation information to the other device when the disturbance area setting section has canceled the disturbance area; and

wherein the event control section cancels prohibition of generation of the disturbance event when the disturbance cancellation information from the other device has been received.

12. The non-transitory computer-readable storage medium storing the program as defined in claim 1 , causing the computer to further function as:

a music reproduction section which reproduces music data;

a storage section which stores the music data and reference timing data which indicates a reference timing corresponding to music for which the position designation operation should be performed for the operation area; and

an operation data acquisition section which acquires operation timing data which indicates an operation timing when the position designation operation has been accepted as the first input operation,

wherein the display control section displays an image which allows the player to know the reference timing corresponding to the music in the first display area as the first display control process; and

wherein the game calculation section compares the reference timing data with the operation timing data.

13. The non-transitory computer-readable storage medium storing the program as defined in claim 12 ,

wherein the music reproduction section changes a reproduction state of the music according to the disturbance area set in the operation area.

14. The non-transitory computer-readable storage medium storing the program as defined in claim 1 ,

wherein the disturbance area setting section sets a plurality of disturbance areas which differ in shape.

15. A non-transitory computer-readable storage medium storing the program as defined in claim 1 ,

wherein the disturbance area is caused to appear, to move, or to disappear while overlapping the operation area.

16. A non-transitory computer-readable storage medium storing the program causing a computer to function as:

a display control section which performs a first display control process which displays an image for proceeding with a game in a first display area, and a second display control process which displays an image that indicates an operation area for which a player should perform a position designation operation in a second display area;

an input processing section which accepts the position designation operation performed for the operation area as a first input operation;

a game calculation section which performs game calculations based on the first input operation which has been accepted by the input processing section; and

an operation area setting section which moves the operation area when a given disturbance condition has been satisfied.

17. A game system comprising:

a display control section which performs a first display control process which displays an image for proceeding with a game in a first display area, and a second display control process which displays an image that indicates an operation area for which a player should perform a position designation operation in a second display area;

an input processing section which accepts the position designation operation performed for the operation area as a first input operation;

a game calculation section which performs game calculations based on the first input operation which has been accepted by the input processing section; and

a disturbance area setting section which sets a disturbance area in the operation area when a given disturbance condition has been satisfied,

wherein the input processing section does not accept the position designation operation performed for the disturbance area as the first input operation.

18. A method of controlling a game system comprising:

causing a display control section to perform a first display control process which displays an image for proceeding with a game in a first display area, and a second display control process which displays an image that indicates an operation area for which a player should perform a position designation operation in a second display area;

causing an input processing section to accept the position designation operation performed for the operation area as a first input operation;

causing a game calculation section to perform game calculations based on the accepted first input operation; and

causing a disturbance area setting section to set a disturbance area in the operation area when a given disturbance condition has been satisfied,

wherein the input processing section does not accept the position designation operation performed for the disturbance area as the first input operation.
