Abstract

An imaging apparatus is capable of imaging with the use of an illumination apparatus including a flash unit capable of changing a radiation direction, and includes: a photometry unit; a display unit that displays information about a result of photometry using the photometry unit; and a display control unit that executes a control related to display on the display unit, wherein when the illumination apparatus is performing a first operation of multiple emissions by the flash unit while changing automatically the radiation direction of the flash unit to a plurality of different directions, the display control unit performs a control so as not to display the information about the photometry result on the display unit.

First claim

What is claimed is:

1. An imaging apparatus which images with the use of an illumination apparatus comprising a flash unit which changes a radiation direction automatically, comprising:
a photometry unit;
a display unit configured to display information about a result of photometry using the photometry unit;
at least one processor and at least one memory functioning as:
a display control unit configured to execute a control related to display on the display unit, and
a determination unit configured to determine, based on a received status signal of the illumination apparatus, whether the illumination apparatus is performing a first operation of multiple emissions by the flash unit while changing automatically the radiation direction of the flash unit to a plurality of different directions,
wherein, when the determination unit determines that the illumination apparatus is performing the first operation, the display control unit performs a control so as not to display the information about the photometry result on the display unit.

2. The imaging apparatus according to claim 1 ,
wherein, when the illumination apparatus is performing the first operation, the display control unit performs the control so as not to display information calculated automatically by the imaging apparatus as the information about the photometry result on the display unit.

3. The imaging apparatus according to claim 2 ,
wherein, when the illumination apparatus is performing the first operation, the display control unit performs a control to display information set manually by a user on the display unit.

4. The imaging apparatus according to claim 1 ,
wherein, when the illumination apparatus is not performing the first operation, the display control unit performs a control to display on the display unit the information about the photometry result according to photometry using the photometry unit.

5. The imaging apparatus according to claim 1 ,
wherein, when the illumination apparatus is performing a second operation of changing automatically the radiation direction of the flash unit without emitting light, the display control unit performs a control to display on the display unit the information about the photometry result according to the photometry using the photometry unit.

6. The imaging apparatus according to claim 1 ,
wherein, when the illumination apparatus is performing the first operation, the display control unit performs a control to display on the display unit information for notifying that the illumination apparatus is performing the first operation.

7. The imaging apparatus according to claim 1 ,
wherein the illumination apparatus is an external illumination apparatus detachable from the imaging apparatus, and
the first operation of the illumination apparatus is an operation of multiple emissions by the flash unit while the radiation direction of the flash unit is automatically changed to a plurality of different directions not depending on an instruction from the imaging apparatus after the first operation is started according to the instruction from the imaging apparatus.

8. The imaging apparatus according to claim 1 ,
wherein the information about the photometry result includes at least one of information about an exposure control value corresponding to the result of photometry using the photometry unit and information about a difference between an exposure control value set by a user and the exposure control value corresponding to the result of photometry using the photometry unit.

9. An imaging apparatus which images with the use of an illumination apparatus comprising a flash unit which changes a radiation direction automatically, comprising:
a photometry unit;
a display unit configured to display information about a result of photometry using the photometry unit;
at least one processor and at least one memory functioning as:
a display control unit configured to execute a control related to display on the display unit, and
a determination unit configured to determine, based on a received status signal of the illumination apparatus, whether the illumination apparatus is performing a first operation of multiple emissions by the flash unit while changing automatically the radiation direction of the flash unit to a plurality of different directions,
wherein, when the determination unit determines that the illumination apparatus is performing the first operation, the display control unit performs a control so as not to update display of the information about the photometry result on the display unit.

10. The imaging apparatus according to claim 9 ,
wherein, when the illumination apparatus is performing the first operation, the display control unit performs the control so as not to update display of information automatically calculated by the imaging apparatus as the information about the photometry result on the display unit.

11. The imaging apparatus according to claim 10 ,
wherein, when the illumination apparatus is performing the first operation, the display control unit performs a control to update display of information set manually by a user as the information about the photometry result on the display unit.

12. The imaging apparatus according to claim 9 ,
wherein, when the illumination apparatus is not performing the first operation, the display control unit performs a control to update display of the information about the photometry result on the display unit according to photometry using the photometry unit.

13. The imaging apparatus according to claim 12 ,
wherein, when the illumination apparatus is performing a second operation of changing automatically the radiation direction of the flash unit without emitting light, the display control unit performs a control to update display of the information about the photometry result on the display unit according to the photometry using the photometry unit.

14. The imaging apparatus according to claim 9 ,
wherein, when the illumination apparatus is performing the first operation, the display control unit performs a control to display information for notifying that the illumination apparatus is performing the first operation.

15. The imaging apparatus according to claim 9 ,
wherein the illumination apparatus is an external illumination apparatus detachable from the imaging apparatus, and
the first operation of the illumination apparatus is an operation of multiple emissions by the flash unit while the radiation direction of the flash unit is automatically changed to a plurality of different directions not depending on an instruction from the imaging apparatus after the first operation is started according to the instruction from the imaging apparatus.

16. The imaging apparatus according to claim 9 ,
wherein the information about the photometry result includes at least one of information about an exposure control value corresponding to the result of photometry using the photometry unit and information about a difference between an exposure control value set by a user and the exposure control value corresponding to the result of photometry using the photometry unit.

17. An imaging apparatus which images with the use of an illumination apparatus comprising a flash unit which changes a radiation direction automatically, comprising:
a photometry unit;
a display unit configured to display information about a result of photometry according to photometry using the photometry unit;
at least one processor and at least one memory functioning as:
a photometry control unit configured to perform a control o
