Abstract

An image capturing apparatus on which a predetermined optical member is mountable, the apparatus comprises an image capturing unit which captures an object image incident on a lens unit, a detection unit which detects inclinations of the image capturing apparatus relative to a plurality of detection axes and a display control unit which performs control to display information indicating the inclinations of the image capturing apparatus on a display unit based on a detection result from the detection unit, wherein the display control unit performs control to display information indicating an inclination of the image capturing apparatus based on inclinations of different axes of the plurality of detection axes depending on a case in which the optical member is not mounted and a case in which the optical member is mounted.

Claims

an image capturing unit configured to capture an object image incident on a lens unit;

a detection unit configured to detect inclinations of the image capturing apparatus relative to a plurality of detection axes; and

a display control unit configured to perform control to display information indicating the inclinations of the image capturing apparatus on a display unit based on a detection result from the detection unit,

wherein the display control unit performs control to display information indicating an inclination of the image capturing apparatus based on inclinations of different axes of the plurality of detection axes depending on a case in which the optical member is not mounted and a case in which the optical member is mounted and performs control to display an inclination around an optical axis of the lens unit as an inclination of the image capturing apparatus when the optical member is not mounted, and display an inclination of the optical axis of the lens unit as an inclination of the image capturing apparatus when the optical member is mounted.

2. The apparatus according to claim 1, wherein the display control unit performs control to display, on the display unit, information indicating an inclination of the image capturing apparatus based on an inclination of the image capturing apparatus, detected by the detection unit, relative to one of an axis parallel to the optical axis of the lens unit and two axes perpendicular to the optical axis of the lens unit, when the predetermined optical member is not mounted, and to display, on the display unit, information indicating inclinations of the image capturing apparatus based on inclinations of the image capturing apparatus relative to the two axes perpendicular to the optical axis of the lens unit.

3. The apparatus according to claim 1, further comprising an optical member detection unit configured to detect mounting of the predetermined optical member,

wherein the display control unit switches whether information indicating an inclination of the image capturing apparatus is displayed based on a specific one of the plurality of detection axes, in accordance with a detection result from the optical member detection unit.

4. The apparatus according to claim 3, wherein the optical member detection unit identifies a type of the predetermined optical member.

5. The apparatus according to claim 4, wherein when the optical member detection unit detects mounting of a macro lens, the display control unit performs control to display a horizontal inclination of the image capturing apparatus as information indicating an inclination of the image capturing apparatus.

6. The apparatus according to claim 4, wherein when the optical member detection unit detects mounting of a fish-eye lens, the display control unit performs control to display an inclination of the optical axis as information indicating an inclination of the image capturing apparatus.

7. The apparatus according to claim 1, wherein the predetermined optical member comprises an omnidirectional capturing adapter configured to form an image of an object around the optical axis of the lens unit on the image capturing unit.

8. The apparatus according to claim 7, wherein the display control unit displays information concerning an inclination of the image capturing apparatus at a position at which the information does not overlap an annular image captured by the image capturing unit, when the omnidirectional capturing adapter is mounted.

9. The apparatus according to claim 1, further comprising a lens unit,

wherein the image capturing unit captures an object image incident on the lens unit, and the optical member is mountable on the lens unit.

10. The apparatus according to claim 1, wherein an optical member including a lens unit is mountable on the image capturing unit.

11. An image capturing apparatus comprising:

a detection unit configured to detect inclinations of the image capturing apparatus relative to a plurality of detection axes; and

a display control unit configured to perform control to display information indicating the inclinations of the image capturing apparatus on a display unit based on a detection result from the detection unit,

wherein the display control unit is configured to switch between a first inclination display in which an inclination of the image capturing apparatus around an optical axis of the lens unit is displayed as an inclination of the image capturing apparatus and a second inclination display in which an inclination of the optical axis of the lens unit is displayed as an inclination of the image capturing apparatus.

12. The apparatus according to claim 11, wherein a predetermined optical member is mountable on the image capturing apparatus, and the display control unit switches between the first display inclination display and the second inclination display in accordance with mounting of the predetermined optical member.

13. A control method for a display apparatus for displaying an inclination of an image capturing apparatus on which a predetermined optical member is mountable and which includes a detection unit configured to detect inclinations relative to a plurality of detection axes, the method comprising:

an acquisition step of acquiring inclination information of the image capturing apparatus which is detected by the detection unit; and

a display control step of performing control to display information indicating the inclinations of the image capturing apparatus on a display apparatus based on the inclination information of the image capturing apparatus acquired in the acquisition step,

wherein in the display control step, control is performed to display information indicating an inclination of the image capturing apparatus based on inclinations of different axes of the plurality of detection axes depending on a case in which the optical member is not mounted and a case in which the optical member is mounted and is performed to display an inclination around an optical axis of the lens unit as an inclination of the image capturing apparatus when the optical member is not mounted, and display an inclination of the optical axis of the lens unit as an inclination of the image capturing apparatus when the optical member is mounted.

14. A non-transitory computer-readable storage medium storing a program for causing a computer to execute the control method for a display apparatus for displaying an inclination of an image capturing apparatus on which a predetermined optical member is mountable and which includes a detection unit configured to detect inclinations relative to a plurality of detection axes, the method comprising:

an acquisition step of acquiring inclination information of the image capturing apparatus which is detected by the detection unit and
