Electronic device and method for controlling electronic device

A method for controlling an image pickup device including a first operation member that can receive a first press operation followed by a second press operation having a pressing amount greater than a pressing amount of the first press operation, the method comprising:

• assigning a function to the first press operation and the second press operation based on a user selection;
• performing a process corresponding to the function assigned to the first press operation in response to the first press operation and performing a process corresponding to the function assigned to the second press operation in response to the second press operation;
• and
• performing control such that if no function is assigned to the first press operation, the function to be assigned to the second press operation is selected from a first function group that includes a function related to playback, and
• if a function is assigned to the first press operation, a function to be assigned to the second press operation is selected from a second function group that includes fewer functions than the first function group and that does not include a function related to playback.

A non-transitory computer-readable storage medium storing one or more programs including executable instructions, which when executed by a computer, cause the computer to

• assign a function to the first press operation and the second press operation based on a user selection;
• perform a process corresponding to the function assigned to the first press operation in response to the first press operation and perform a process corresponding to the function assigned to the second press operation in response to the second press operation;
• and
• perform control such that if no function is assigned to the first press operation, the function to be assigned to the second press operation is selected from a first function group that includes a function related to playback, and
• if a function is assigned to the first press operation, a function to be assigned to the second press operation is selected from a second function group that includes fewer functions than the first function group and that does not include a function related to playback.
