Lens unit, method for controlling lens unit, imaging apparatus, and method for controlling imaging apparatus

A lens unit that can be attached to an imaging apparatus, the lens unit comprising:

• a display unit configured to switch and display information relating to a plurality of items;
• a lens control unit configured to exchange information in communication with the imaging apparatus and control the display on the display unit;
• and
• a first storage unit configured to store first information indicating an item selected from among items of information that can be displayed on the display unit,
• wherein, based on information received from the imaging apparatus, the lens control unit switches between display and non-display, on the display unit, of information relating to the item corresponding to the first information stored in the first storage unit.

An imaging apparatus to which a lens unit including a display unit configured to switch and display information relating to a plurality of items can be attached, the imaging apparatus comprising:

• a control unit configured to exchange information in communication with the lens unit and transmit to the lens unit an instruction regarding display on the display unit;
• and
• a second storage unit configured to store information received from the lens unit,
• wherein the control unit receives, from a lens unit attached to the imaging apparatus, first information indicating an item selected from among items of information that can be displayed on the display unit, and stores the received first information in the second storage unit, and
• wherein the control unit transmits, to a lens unit attached to the imaging apparatus, the instruction regarding the display on the display unit based on the first information stored in the second storage unit.

A method for controlling a lens unit that can be attached to an imaging apparatus and includes a display unit configured to display information and a first storage unit, the method comprising:

• switching and displaying, on the display unit, information relating to a plurality of items;
• and
• storing, in the first storage unit, first information indicating an item selected from among items of information that can be displayed on the display unit,
• wherein, when the display on the display unit is turned off, the first information corresponding to an item of information displayed on the display unit is stored in the first storage unit, and, when the display on the display unit is turned on, information relating to the item indicated by the first information stored in the first storage unit is displayed on the display unit.

A method for controlling a lens unit that can be attached to an imaging apparatus and includes a display unit configured to display information and a first storage unit, the method comprising:

• exchanging information in communication with the imaging apparatus;
• switching and displaying, on the display unit, information relating to a plurality of items;
• and
• storing, in the first storage unit, first information indicating an item selected from among items of information that can be displayed on the display unit,
• wherein, based on information received from the imaging apparatus, switching display and non-display, on the display unit, information relating to the item corresponding to the first information stored in the first storage unit is performed.

A method for controlling an imaging apparatus to which a lens unit including a display unit configured to switch and display information relating to a plurality of items can be attached and includes a second storage unit, the method comprising:

• exchanging information in communication with the lens unit and transmitting to the lens unit an instruction regarding display on the display unit;
• and
• storing, in the second storage unit, information received from the lens unit,
• wherein first information indicating an item selected from among items of information that can be displayed on the display unit is received from a lens unit attached to the imaging apparatus, and the received first information is stored in the second storage unit, and
• wherein the instruction regarding the display on the display unit based on the first information stored in the second storage unit is transmitted to a lens unit attached to the imaging apparatus.
