Image pickup apparatus, control method, and storage medium

An apparatus comprising:

• a sensor configured to pick up images;
• a setting device configured to set a photometry mode;
• and
• at least one processor and a memory coupled to the at least one processor storing instructions that, when executed by the at least one processor, cause the at least one processor to function as:
• a first calculation unit configured to calculate a first value from a whole of an image;
• a second calculation unit configured to calculate a second value from, out of the whole of the image, a region whose value is equal to or higher than a first threshold;
• and
• a third calculation unit configured to calculate a third value from, out of the whole of the image, a region whose value is a second threshold or less, the second threshold being different from the first threshold used by the second calculation unit;
• and
• a determination unit configured to determine a target value,
• wherein the determination unit is configured to:
• use the first value to determine the target value in a case where the photometry mode set by the setting device is a first mode;
• and
• use the first value, the second value, and the third value to determine the target value in a case where the photometry mode set by the setting device is a second mode that is different from the first mode.

A method comprising:

• picking up images;
• setting a photometry mode;
• calculating a first value from a whole of an image;
• calculating a second value from, out of the whole of the image, a region whose value is a predetermined threshold or more;
• determining a target value;
• using the first value to determine the target value in a case where the photometry mode set by the setting device is a first;
• and
• using the second value to determine the target value in a case where the photometry mode set by the setting device is a second mode that is different from the first mode,
• wherein the predetermined threshold is a value that is higher than the target value in the first mode.

• calculating a second value from, out of the whole of the image, a region whose value is equal to or higher than a first threshold;
• calculating a third value from, out of the whole of the image, a region whose value equal to or lower than is a second threshold, the second threshold being different from the first threshold;
• determining a target value;
• using the first value to determine the target value in a case where the photometry mode is a first mode;
• and
• using the first value, the second value, and the third value to determine the target value in a case where the photometry mode is a second mode that is different from the first mode.

A non-transitory computer-readable storage medium storing a program for causing a computer to execute a method, the method comprising:

• picking up images;
• setting a photometry mode;
• calculating a first value from a whole of an image;
• calculating a second value from, out of the whole of the image, a region whose value is a predetermined threshold or more;
• determining a target value;
• using the first value to determine the target value in a case where the photometry mode set by the setting device is a first mode is set;
• and
• using the second value to determine the target value in a case where the photometry mode set by the setting device is a second mode that is different from the first mode,
• wherein the predetermined threshold is a value that is higher than the target value in the first mode.
