Abstract

An electronic device includes a touch detection unit that detects a touch operation executed on an operation surface, a pressure detection unit that detects a pressing force of the touch operation, and a control unit that controls executing a different function based on the detected pressing force of the touch operation when the touch operation is detected by the touch detection unit. In a case where a touch operation is detected again within a predetermined period from a previous touch operation after the control unit has controlled a function based on the pressing force to be executed based on the touch operation, the control unit controls a same function as the function executed based on the previous touch operation to be executed regardless of the pressing force.

First claim

What is claimed is:

1. An electronic device comprising:
a touch detection unit configured to detect a touch operation executed on an operation surface;
a pressure detection unit configured to detect a pressing force of the touch operation; and
a control unit configured to control, when the touch operation is detected, executing a function based on the detected pressing force of the touch operation,
wherein, when the touch operation is detected again before a predetermined period elapses after the control unit has controlled the function corresponding to the pressing force to be executed based on a previous touch operation, the control unit controls executing a same function as the function executed based on the previous touch operation regardless of the pressing force of the touch operation that is detected again before the predetermined period elapses.

2. The electronic device according to claim 1 , wherein, when the touch operation is detected again after the predetermined period elapses, the control unit controls executing a function based on the pressing force of the touch operation detected again after the predetermined period elapses.

3. The electronic device according to claim 1 , wherein the control unit controls a function corresponding to a pressing force to be executed when a move operation in which a touch position is moved is detected by the touch detection unit.

4. The electronic device according to claim 1 , wherein, when a first touch operation is detected by the touch detection unit, the control unit determines a function to be executed based on a pressing force of touch-down executed in the first touch operation and controls the determined function to be executed when execution of a move operation in which a touch position is moved is detected in the first touch operation.

5. The electronic device according to claim 4 , wherein, when a second touch operation is detected before the predetermined period elapses after the first touch operation is released from the operation surface, the control unit controls executing the function executed by the first touch operation when a move operation is executed by the second touch operation regardless of the pressing force of the second touch operation.

6. The electronic device according to claim 1 , further comprising a notification unit configured to notify a user that the same function as the function executed by the previous touch operation can be executed by executing a touch operation again before the predetermined period elapses.

7. The electronic device according to claim 6 , wherein the notification unit ends the notification when the predetermined period elapses.

8. The electronic device according to claim 1 , wherein, when a specific operation is executed within the predetermined period, the control unit controls executing the function corresponding to the pressing force of the touch operation even if a touch operation is executed again within the predetermined period.

9. The electronic device according to claim 8 , wherein the specific operation is a touch operation without moving a touch position.

10. The electronic device according to claim 1 , wherein the control unit controls the predetermined period to be changed based on a moving amount of a touch position moved in the previous touch operation.

11. The electronic device according to claim 1 , wherein the control unit controls processing for changing a setting value of a different setting item to be executed based on the pressing force of the touch operation that is detected again before the predetermined period elapses.

12. The electronic device according to claim 11 , wherein, when the touch operation is detected by the touch detection unit, the control unit determines a setting item of which a setting value is changed based on the pressing force of touch-down executed in the touch operation, and controls the setting value of the determined setting item to be changed when execution of a move operation in which a touch position that is moved is detected in the touch operation.

13. The electronic device according to claim 12 , wherein, when the pressing force of the touch operation is changed without executing the move operation after the touch-down of the touch operation, the control unit determines a setting item of which a setting value is changed based on a changed pressing force.

14. The electronic device according to claim 11 further comprising a display control unit configured to display a plurality of setting items on a display unit,
wherein, when a setting item of which a setting value is changed is determined by the control unit, the display control unit controls the determined setting item to be displayed in a recognizable manner.

15. The electronic device according to claim 14 , wherein the display control unit continues display of the determined setting item in a recognizable manner even after the touch operation is released from the operation surface, and ends the display thereof in the recognizable manner when the predetermined period elapses from when the touch operation is released from the operation surface.

16. The electronic device according to claim 11 , wherein the control unit changes the predetermined period based on a setting value changed based on the touch operation.

17. The electronic device according to claim 16 , wherein the control unit determines the predetermined period based on a change amount of the setting value or the changed setting value.

18. The electronic device according to claim 11 , wherein, when a setting value of a setting item is changed to an upper limit value or a lower limit value based on the touch operation, the control unit controls executing a function based on a next pressing force of the touch operation regardless of time elapsed until a next touch operation is detected.

19. A control method of an electronic device comprising:
detecting a touch operation executed on an operation surface;
detecting a pressing force of the touch operation; and
performing control to execute a function based on the detected pressing force of the touch operation,
wherein, when the touch operation is detected again before a predetermined period of time elapses after performing control to execute the function based on the pressing force based on a previous touch operation, control is performed to execute a same function as the function executed based on the previous touch operation regardless of the pressing force of the touch operation that is detected again before the predetermined period elapses.

20. A non-transitory computer-readable storage medium storing a program for causing a computer to execute a control method, the control method comprising:
detecting a touch operation executed on an operation surface;
detecting a pressing force of the touch operation; and
performing control to execute a function based on the detected pressing force of the touch operation,
wherein, when the touch operation is detected again before a predetermined period elapses after performing control to execute the function based on the pressing force based on a previous touch operation, control is performed to execute a same function as the function executed based on the previous touch operation regardless of the pressing force of the touch operation that is detected again before the predetermined period elapses.
