Display control apparatus and control method therefor

1. A display control apparatus comprising:

at least one processor and/or circuit configured to function as:

a change unit configured to change amount of application of a predetermined effect which is to be applied to a selected subject from a plurality of selectable subjects; and

a control unit configured to perform control to display a first item which makes the selected subject distinguishable from other subjects, together with the selected subject and subjects not selected from the plurality of selectable subjects,

wherein, in a state where the first item is displayed, in response to the change unit starting changing the amount of application of the predetermined effect, the control unit performs control to hide the first item and to display both of the selected subject and the subjects not selected from the plurality of selectable subjects.

2. The display control apparatus according to claim 1 , wherein the control unit performs control to display the selected subject in such a way as to be distinguishable from the subjects not selected from the plurality of selectable subjects by displaying the first item in superimposition on the selected subject.

3. The display control apparatus according to claim 1 , the at least one processor and/or circuit further configured to function as:

a touch detection unit configured to detect a touch operation on a display surface,

wherein, in response to the touch detection unit having detected movement of a position of the touch operation, the control unit performs control not to display the selected subject in such a way as to be distinguishable from the subjects not selected from the plurality of selectable subjects.

4. The display control apparatus according to claim 1 , wherein the predetermined effect is an effect in which illumination from a virtual light source is performed onto the selected subject, and the change unit is able to change a direction of illumination from the virtual light source.

5. The display control apparatus according to claim 1 , wherein, in response to the change unit ending changing the amount of application of the predetermined effect, the control unit performs control to display the selected subject in such a way as to be distinguishable from the subjects not selected from the plurality of selectable subjects.

6. The display control apparatus according to claim 1 , wherein, in response to the change unit changing the amount of application of the predetermined effect, the control unit performs control to update a second item which indicates amount of application of the predetermined effect and display the updated second item.

7. The display control apparatus according to claim 6 , wherein, even when the change unit starts changing the amount of application of the predetermined effect, the control unit performs control to keep the second item displayed.

8. A control method for a display control apparatus, the control method comprising:

changing amount of application of a predetermined effect which is to be applied to a selected subject from a plurality of selectable subjects;

performing control to display a first item which makes the selected subject distinguishable from other subjects, together with the selected subject and subjects not selected from the plurality of selectable subjects; and

in a state where the first item is displayed, in response to changing the amount of application of the predetermined effect being started, performing control to hide the first item and to display both of the selected subject and the subjects not selected from the plurality of selectable subjects.

9. A non-transitory computer-readable storage medium storing computer-executable instructions that, when executed by a computer, cause the computer to perform a control method for a display control apparatus, the control method comprising:

changing amount of application of a predetermined effect which is to be applied to a selected subject from a plurality of selectable subjects;

performing control to display a first item which makes the selected subject distinguishable from other subjects, together with the selected subject and subjects not selected from the plurality of selectable subjects; and

in a state where the first item is displayed, in response to changing the amount of application of the predetermined effect being started, performing control to hide the first item and to display both of the selected subject and the subjects not selected from the plurality of selectable subjects.
