1. A display control apparatus comprising:
at least one memory and at least one processor which function as:
a display control unit configured to perform control to display a display item indicating a degree of focus;
a first obtainment unit configured to obtain size information of an image to be recorded;
a second obtainment unit configured to obtain a defocus amount for a focus detection region;
a determination unit configured to determine the degree of focus based on the defocus amount and based on the size information of the image to be recorded; and
a change unit configured to change a display style of the display item based on the degree of focus determined by the determination unit.
2. The display control apparatus according to claim 1 , wherein the display control unit displays the display item indicating the degree of focus superimposed on a live view image captured by an image sensor.
3. The display control apparatus according to claim 1 , wherein the determination unit determines that, in a case where the defocus amount is the same, the degree of focus is higher for a case where the size of the image to be recorded is smaller than for a case where the size of the image to be recorded is larger.
4. The display control apparatus according to claim 3 , wherein the display item has at least two indicators, and is configured to represent the degree of focus by a distance between the two indicators, and wherein the change unit changes the distance between the two indicators based on the degree of focus in a case where the defocus amount is the same.
5. The display control apparatus according to claim 4 , wherein the change unit changes the distance between the two indicators to be smaller for a case where the degree of focus is higher than for a case where the degree of focus is lower.
6. The display control apparatus according to claim 3 , wherein the display item has at least two indicators, and is configured to represent the degree of focus by a tilt angle between the two indicators, and wherein the change unit changes the tilt angle between the two indicators based on the degree of focus in a case where the defocus amount is the same.
7. The display control apparatus according to claim 6 , wherein the change unit changes the tilt angle between the two indicators to be smaller for a case where the degree of focus is higher than for a case where the degree of focus is lower.
8. The display control apparatus according to claim 1 , wherein the size information of the image to be recorded is a resolution of a still image.
9. The display control apparatus according to claim 1 , wherein the size information of the image to be recorded is a resolution of a moving image.
10. The display control apparatus according to claim 1 , wherein the size information of the image to be recorded is a crop size of a still image.
11. The display control apparatus according to claim 1 , wherein the size information of the image to be recorded is a crop size of a moving image.
12. The display control apparatus according to claim 1 , wherein the display item includes a plurality of indicators indicating a degree of focus for the focus detection region, the plurality of indicators have at least a first indicator and a second indicator indicating a degree of focus according to a relationship of display positions with each other, and a third indicator indicating an in-focus position, and wherein the first indicator and the second indicator are merged and align with a position indicated by the third indicator, thereby indicating that a subject of the focus detection region is in focus.
13. The display control apparatus according to claim 1 , wherein
the determination unit determines whether a subject of the focus detection region is in an in-focus state or in an out-of-focus state; and
a range of degree of focus information for which the out-of-focus state is determined varies in accordance with the size information of the image to be recorded.
14. An image capturing apparatus comprising:
an image sensor configured to capture an image of a subject;
a display configured to display an image; and
a display control apparatus including at least one memory and at least one processor which function as:
a display control unit configured to perform control to display a display item indicating a degree of focus;
a first obtainment unit configured to obtain size information of an image to be recorded;
a second obtainment unit configured to obtain a defocus amount for a focus detection region;
a determination unit configured to determine the degree of focus based on the defocus amount and based on the size information of the image to be recorded; and
a change unit configured to change a display style of the display item based on the degree of focus determined by the determination unit.
15. A method of controlling a display control apparatus, the method comprising:
performing control to display a display item indicating a degree of focus;
obtaining size information of an image to be recorded;
obtaining a defocus amount for a focus detection region;
determining the degree of focus based on the defocus amount and based on the size information of the image to be recorded; and
changing a display style of the display item based on the determined degree of focus.
16. A non-transitory computer-readable storage medium that stores programs for causing a computer to function as each unit of a display control apparatus, the display control apparatus comprising:
at least one memory and at least one processor which function as:
a display control unit configured to perform control to display a display item indicating a degree of focus;
a first obtainment unit configured to obtain size information of an image to be recorded;
a second obtainment unit configured to obtain a defocus amount for a focus detection region;
a determination unit configured to determine the degree of focus based on the defocus amount and based on the size information of the image to be recorded; and
a change unit configured to change a display style of the display item based on the degree of focus determined by the determination unit.
