When a second screen is displayed on the display surface, a second function is performed in response to a touch operation in which the duration time of the touch on the operation surface is less than the predetermined time. ## Claims ### Claim 1 An electronic device comprising: a detector capable of detecting a touch operation on an operation surface; and a memory and at least one processor which function as: a control unit configured to perform one or more functions in response to one or more touch operations performed on an operation surface for at least a first period, and a setting unit configured to set a response time to a second period longer than the first period in response to a user operation, wherein the control unit performs control such that: (1) when a first screen is displayed on a display surface in a case where the response time is set to the second period by the setting unit: (a) in response to a first touch operation having a duration time on the operation surface of less than the second period, not performing a function corresponding to the first touch operation, and (b) in response to a second touch operation having a duration time on the operation surface of at least the second period, performing a first function corresponding to the second touch operation and (2) when a second screen is displayed on the display surface in a case where the response time is set to the second period by the setting unit: in response to a third touch operation having a duration time on the operation surface of at least the first period and less than the second period, performing a second function. ### Claim 2 (depends on 1) The electronic device according to claim 1, wherein in response to detection of starting of a respective touch operation on the operation surface, the control unit starts driving a timer to measure a duration time of the respective touch operation on the operation surface. ### Claim 3 (depends on 1) The electronic device according to claim 1, wherein The second touch operation is an operation in which a difference between a touch position when the second touch operation on the operation surface is started and a touch position after an elapse of the second period is less than a predetermined amount. ### Claim 4 (depends on 1) The electronic device according to claim 1, wherein when the first screen is displayed on the display surface, the control unit performs control to display, on the display surface, a remaining time until the duration time of a respective touch operation on the operation screen reaches the second period. ### Claim 5 (depends on 1) The electronic device according to claim 1, wherein the first screen is a standby screen displayed regardless of an operation by a user after the electronic device is activated, and the second screen is a screen displayed in response to an operation by the user other than the activating operation after the electronic device is activated. ### Claim 6 (depends on 1) The electronic device according to claim 1, wherein the first screen is a screen in which a function of changing a setting of the electronic device is assigned to at least one of an operation of starting a touch and an operation of ending a touch without moving a position after a touch, and the second screen is a screen in which the function of changing the setting of the electronic device is not assigned to the operation of starting a touch and the operation of ending a touch without moving the position after a touch. ### Claim 7 (depends on 1) The electronic device according to claim 1, wherein the electronic device is a device for performing control such that content is recorded on a recording medium, the first screen is a screen in which a function of changing a setting having influence on the content recorded on the recording medium is assigned to at least one of an operation of starting a touch and an operation of ending a touch without moving a position after a touch, and the second screen is a screen in which the function of changing the setting having influence on the content recorded on the recording medium is not assigned to the operation of starting a touch and the operation of ending a touch without moving the position after a touch. ### Claim 8 (depends on 6) The electronic device according to claim 6, wherein the electronic device is capable of performing control such that automatic focusing is performed with respect to a set AF position, and the function of changing the setting of the electronic device is a function of changing the AF position. ### Claim 9 (depends on 7) The electronic device according to claim 7, wherein the electronic device is capable of performing control such that automatic focusing is performed with respect to a set AF position, and the function of changing the setting having influence on the content recorded on the recording medium is a function of changing the AF position. ### Claim 10 (depends on 7) The electronic device according to claim 7, wherein the function of changing the setting having influence on the content recorded on the recording medium does not include a function of changing a display position showing a focus degree. ### Claim 11 (depends on 1) The electronic device according to claim 1, wherein the first screen is a screen in which a function assigned to an operation of moving a touch position after a touch is not present, and the second screen is a screen in which the function assigned to the operation of moving a touch position after a touch is present. ### Claim 12 A method for controlling an electronic device, the method comprising: detecting a touch operation on an operation surface; and performing control to: perform one or more functions in response to one or more touch operations performed on an operation surface for at least a first period; and setting a response time to a second period longer than the first period in response to a user operation, such that: (1) when a first screen is displayed on a display surface in a case where the response time is set to the second period by the setting unit: (a) in response to a first touch operation having a duration time on the operation surface of less than the second period, not performing a function corresponding to the first touch operation, and (b) in response to a second touch operation having a duration time on the operation surface of at least the second period, performing a first function corresponding to the second touch operation and (2) when a second screen is displayed on the display surface in a case where the response time is set to the second period: in response to a third touch operation having a duration time on the operation surface of at least the first period and less than the second period, performing a second function. ### Claim 13 (depends on 1) A non-transitory computer-readable storage medium storing a program for causing a computer to function as a control unit of the electronic device according to claim 1.
