Abstract
In an image capturing apparatus, in a case where a change is made from a first magnification ratio into a second magnification ratio which is greater than the first magnification ratio in a state in which a live view is displayed at the first magnification ratio and a first AF mode is set, the live view image is enlarged and displayed at the second magnification ratio, and the AF mode is set to a second AF mode. In a case where a change to the first magnification ratio is made after the second magnification ratio is set, the first AF mode is set, and a focus adjustment position is set based on a focus adjustment position which is set in the second AF mode.
Claims13
An image capturing apparatus comprising:
- an image capturing unit;
- a display controller configured to perform control such that a live view image which is captured by the image capturing unit is displayed on a display unit;
- a magnification ratio changing unit configured to change a magnification ratio of the live view image which is displayed on the display unit;
- an AF mode setting unit configured to set one of a plurality of AF modes in which a focus adjustment position to be used for focus detection is selected according to the set AF mode;
- and
- a controller configured to perform control such that in a case where a first AF mode is set by the AF mode setting unit and a change is made from a first magnification ratio to a second magnification ratio which is greater than the first magnification ratio by the magnification ratio changing unit, the live view image is enlarged and displayed at the second magnification ratio and the AF mode is set to a second AF mode, and such that in a case where a change to the first magnification ratio is made after the second magnification ratio is set, the first AF mode is set and the focus adjustment position is set based on a focus adjustment position which is set in the second AF mode.
A control method for an image capturing apparatus which includes an image capturing unit, the method comprising:
- a display control step of performing control such that a live view image which is captured by the image capturing unit is displayed on a display unit;
- a magnification ratio changing step of changing a magnification ratio of the live view image which is displayed on the display unit;
- an AF mode setting step of setting one of a plurality of AF modes in which a focus adjustment position to be used for focus detection is selected according to the set AF mode;
- and
- a control step of performing control such that in a case where a first AF mode is set and a change is made from a first magnification ratio to a second magnification ratio which is greater than the first magnification ratio by the magnification ratio changing step, the live view image is enlarged and displayed at the second magnification ratio and the AF mode is set to a second AF mode, and such that in a case where a change to the first magnification ratio is made after the second magnification ratio is set, the first AF mode is set and the focus adjustment position is set based on a focus adjustment position which is set in the second AF mode.
