Setting device, setting method, setting program, and camera

A setting method comprising:

• detecting contact with an upper surface of an endlessly rotatable operation dial;
• validating switching of a setting by the operation dial in a case where the contact with the upper surface of the operation dial is detected;
• switching sequentially the setting in response to a rotation operation of the operation dial in a case where the switching of the setting by the operation dial is valid;
• displaying an image picture of a lock release button on the rotation center of the operation dial;
• and
• displaying a currently selected setting at a current setting display position.

A non-transitory computer readable recording medium storing a setting program causing a computer to realize functions comprising:

• a function of determining the presence or absence of contact with an upper surface of an operation dial based on an output from a contact detection unit provided on the upper surface of the endlessly rotatable operation dial;
• a function of validating switching of a setting by the operation dial in a case where the contact with the upper surface of the operation dial is determined to be present;
• a function of switching sequentially the setting in response to a rotation operation of the operation dial in a case where the switching of the setting by the operation dial is valid;
• a function of displaying an image picture of a lock release button on the rotation center of the operation dial;
• and
• a function of displaying a currently selected setting at a current setting display position.
