Abstract
An image pickup apparatus includes a detection unit configured to detect a specific object from an image picked up by an image pickup unit, a determination unit configured to determine whether a subject is a moving object, and a setting unit configured to set a sensitivity to be used when the determination unit determines that the subject is a moving object. The setting unit sets the sensitivity depending on whether the specific object is detected by the detection unit.
Claims22
An image pickup apparatus comprising:
- at least one memory configured to store instructions;
- and
- at least one processor communicatively connected to the at least one memory and configured to execute the stored instructions to function as:
- a detection unit configured to detect a specific object from an image picked up by an image pickup unit;
- a determination unit configured to determine whether a subject is a moving object;
- a setting unit configured to set a sensitivity to be used when the determination unit determines that the subject is a moving object;
- and
- a focus detection unit configured to detect a focus state based on a signal output from the image pickup unit,
- wherein the determination unit determines whether the subject is a moving object based on the focus state,
- wherein the setting unit sets the sensitivity depending on whether the specific object is detected by the detection unit,
- wherein the focus detection unit detects a defocus amount as the focus state,
- wherein the determination unit determines that the subject is a moving object, in a case where a number of times in a row, that a difference between a latest defocus amount and a last defocus amount among defocus amounts of the subject obtained by the focus detection unit in time series is more than or equal to a threshold, is more than or equal to a predetermined number of times.

- at least one memory configured to store instructions;
- and
- at least one processor communicatively connected to the at least one memory and configured to execute the stored instructions to function as:
- a detection unit configured to detect a specific object from an image picked up by an image pickup unit;
- a determination unit configured to determine whether a subject is a moving object;
- and a setting unit configured to set a sensitivity to be used when the determination unit determines that the subject is a moving object,
- wherein the setting unit sets the sensitivity depending on whether the specific object is detected by the detection unit,
- wherein the sensitivity is set lower in a case where a distance from the image pickup apparatus to the subject is less than a threshold than in a case where the distance is more than or equal to the threshold.

A control method for an image pickup apparatus, the control method comprising:
- detecting a specific object from an image picked up by an image pickup unit;
- determining whether a subject is a moving object;
- setting a sensitivity to be used when it is determined that the subject is a moving object;
- detecting a focus state based on a signal output from the image pickup unit;
- and
- determining whether the subject is a moving object based on the focus state,
- wherein the sensitivity is set depending on whether the specific object is detected,
- wherein a defocus amount is detected as the focus state,
- wherein it is determined that the subject is a moving object, in a case where a number of times in a row, that a difference between a latest defocus amount and a last defocus amount among defocus amounts of the subject obtained in time series is more than or equal to a threshold, is more than or equal to a predetermined number of times.

A control method for an image pickup apparatus, the control method comprising:
- detecting a specific object from an image picked up by an image pickup unit;
- determining whether a subject is a moving object;
- and setting a sensitivity to be used when it is determined that the subject is a moving object,
- wherein the sensitivity is set depending on whether the specific object is detected,
- wherein the sensitivity is set lower in a case where a distance from the image pickup apparatus to the subject is less than a threshold than in a case where the distance is more than or equal to the threshold.
