Apparatus, control method, and storage medium

A method for controlling an apparatus capable of communicating with a capturing apparatus, the method comprising:

• acquiring an image captured by the capturing apparatus;
• acquiring first exposure setting value determined by the capturing apparatus based on a luminance of a first region in the image;
• determining second exposure setting value based on a luminance of a specific region;
• determining an exposure correction value based on the first exposure setting value and the second exposure setting value;
• outputting, in a case where the exposure correction value is larger than a predetermined value, a new exposure correction value that is approximately equal to the predetermined value, to the capturing apparatus;
• and
• outputting, in a case where the exposure correction value is equal to or smaller than the predetermined value, the exposure correction value, to the capturing apparatus.

A non-transitory computer-readable storage medium storing computer-executable instructions that, when executed by a computer, cause the computer to perform a method for controlling an apparatus capable of communicating with a capturing apparatus, the method comprising:

• acquiring an image captured by the capturing apparatus;
• acquiring first exposure setting value determined by the capturing apparatus based on a luminance of a first region in the image;
• determining second exposure setting value based on a luminance of a specific region;
• determining an exposure correction value based on the first exposure setting value and the second exposure setting value;
• outputting, in a case where the exposure correction value is larger than a predetermined value, a new exposure correction value that is approximately equal to the predetermined value, to the capturing apparatus;
• and
• outputting, in a case where the exposure correction value is equal to or smaller than the predetermined value, the exposure correction value, to the capturing apparatus.
