Abstract

A set magnification of a magnified view during imaging standby and a set magnification of a magnified view in an AF-plus-MF mode are compared to determine whether the magnification of the magnified view during imaging standby is higher than the magnification of the magnified view in the AF-plus-MF mode. As a result of the determination, if the magnification of the magnified view during imaging standby is lower than or equal to the magnification of the magnified view in the AF-plus-MF mode, a live-view image is displayed at a magnification equal to the magnification set for the AF-plus-MF mode. If the magnification of the magnified view during imaging standby is higher than the magnification of the magnified view in the AF-plus-MF mode, the live-view image is displayed at a magnification equal to the magnification at which the live-view image has been displayed during imaging standby.

First claim

What is claimed is:

1. An imaging control apparatus comprising:
a magnification instruction unit configured to provide an instruction to magnify a live-view image obtained by an imaging unit;
a manual focus operation unit configured to receive an operation of manually adjusting focus; and
a control unit configured to:
perform control to display the live-view image in magnified form at a first magnification in response to the instruction provided by the magnification instruction unit; and
perform control to, in response to the manual focus operation unit receiving the operation, display the live-view image at a higher magnification among the first magnification and a second magnification, the second magnification being determined in advance as a magnification at which the live-view image is displayed in response to the manual focus operation unit receiving the operation.

2. The imaging control apparatus according to claim 1 , further comprising:
a selection unit configured to select the second magnification in accordance with user operation.

3. The imaging control apparatus according to claim 1 , further comprising:
a comparison unit configured to compare the first magnification and the second magnification,
wherein the control unit performs control to display the live-view image at a higher magnification among the first magnification and the second magnification in accordance with a comparison result obtained by the comparison unit.

4. The imaging control apparatus according to claim 1 , further comprising:
a determination unit configured to determine the first magnification in accordance with user operation to magnify the live-view image in accordance with the instruction provided by the magnification instruction unit.

5. The imaging control apparatus according to claim 1 , wherein
the control unit performs control to display the live-view image in magnified form at the first magnification in response to the manual focus operation unit receiving the operation in such a manner that an indication indicating that the live-view image is displayed at the first magnification is displayed together with the live-view image.

6. The imaging control apparatus according to claim 1 , further comprising:
a storage unit configured to store one or more set values of the first magnification and one or more set values of the second magnification.

7. The imaging control apparatus according to claim 1 , wherein
the manual focus operation unit is capable of receiving an operation of manually adjusting focus after the imaging unit starts an imaging preparation operation, and
the imaging preparation operation includes adjusting focus by using autofocus.

8. The imaging control apparatus according to claim 7 , wherein
the manual focus operation unit receives an operation of adjusting the focus from a position at which the focus is adjusted by using autofocus.

9. The imaging control apparatus according to claim 1 , wherein
the control unit performs control to display the live-view image at a magnification specified by the magnification instruction unit after the imaging unit completes an imaging operation.

10. The imaging control apparatus according to claim 9 , further comprising:
a storage unit configured to store one or more set values of the first magnification and one or more set values of the second magnification.

11. A control method for an imaging control apparatus including a manual focus operation unit configured to receive an operation of manually adjusting focus, the control method comprising:
a magnification instruction step of providing an instruction to magnify a live-view image obtained by an imaging unit; and
a control step of performing control to display the live-view image in magnified form at a first magnification in response to the instruction provided in the magnification instruction step, and performing control to, in response to the manual focus operation unit receiving the operation, display the live-view image at a higher magnification among the first magnification and a second magnification, the second magnification being determined in advance as a magnification at which the live-view image is displayed in response to the manual focus operation unit receiving the operation.

12. A non-transitory computer-readable storage medium storing a program for causing a computer to function as the magnification instruction unit, the manual focus operation unit, and the control unit in the imaging control apparatus according to claim 1 .

13. A non-transitory computer-readable storage medium storing a program for causing a computer to function as the magnification instruction unit, the manual focus operation unit, and the control unit in the imaging control apparatus according to claim 10 .
