Abstract:
1. An electronic apparatus comprising: an operation member rotatable in a first direction and a second direction from an initial state with respect to a main body; a first detection unit configured to detect rotation of the operation member in the first direction from the initial state by an angle not less than a first angle, and further configured to detect rotation of the operation member in the second direction from the initial state by an angle not less than a second angle; a second detection unit configured to detect rotation of the operation member in the first direction from the initial state by an angle not less than a third angle larger than the first angle, and further configured to detect rotation of the operation member in the second direction from the initial state by an angle not less than a fourth angle smaller than the second angle; and a control unit configured to start a first operation when the first detection unit detects rotation of the operation member in a state in which the second detection unit has not detected rotation of the operation member, and to start a second operation different from the first operation when the second detection unit detects rotation of the operation member in a state in which the first detection unit has not detected rotation of the operation member, wherein the control unit is further configured to change a control value for the second operation when the first detection unit detects rotation of the operation member in a state in which the second detection unit has detected rotation of the operation member, and change a control value for the first operation when the second detection unit detects rotation of the operation member in a state in which the first detection unit has detected rotation of the operation member.
