Image pickup apparatus and control method therefor
An image pickup apparatus is configured to change a shooting process based on data on a shot image. The image pickup apparatus is configured to, when the image pickup apparatus changes the shooting process, assign greater weights to the data on the shot image based on an instruction from a user than to the data on the shot image automatically processed.
1. An imaging apparatus comprising:
an imaging unit configured to output image data; and
one or more processors and/or circuitry which functions as:
a control unit configured to control a direction of the imaging unit so that the imaging unit is directed to a subject;
a subject detection unit configured to detect a subject in the image data output by the imaging unit; and
a state acquisition unit configured to acquire information about a holding state of the imaging apparatus among a plurality of holding states including at least one of a state where the imaging apparatus is placed to capture an image, a state where the imaging apparatus is held by a hand, a state where the imaging apparatus is hung from a neck, and a state where the imaging apparatus is wearable,
wherein the control unit is configured to set a change range in which the direction of the imaging unit is changed based on the information about the holding state of the imaging apparatus acquired by the state acquisition unit.
2. The imaging apparatus according to claim 1 , wherein the control unit is configured to control the imaging unit to rotate in a pan direction and a tilt direction.
3. The imaging apparatus according to claim 1 , wherein the imaging unit is configured to input detection information about the subject detected by the subject detection unit into a neural network and learn the change range.
4. The imaging apparatus according to claim 1 , wherein the imaging unit is configured to input a captured image into a neural network and learn the change range.
5. The imaging apparatus according to claim 1 , wherein the information about the holding state of the imaging apparatus is information about an attachment attached to the imaging apparatus.
6. The imaging apparatus according to claim 1 , wherein the information about the holding state of the imaging apparatus is acquired based on an output of a shake detection unit configured to detect a shake of an apparatus.
7. The imaging apparatus according to claim 1 , wherein the processors and/or circuitry further function as an automatic imaging unit configured to perform imaging processing of recording the image data output by the imaging unit based on information about the subject detected by the subject detection unit.
8. The imaging apparatus according to claim 7 ,
wherein the subject detected by the subject detection unit is a human face, and
wherein the automatic imaging unit is configured to perform the imaging processing based on a frequency of a subject being searched and an expression of a person.
9. The imaging apparatus according to claim 7 ,
wherein the subject detected by the subject detection unit is an object, and
wherein the automatic imaging unit is configured to perform the imaging processing based on object recognition.
10. The imaging apparatus according to claim 7 , wherein the automatic imaging unit is configured to perform the imaging processing using a parameter generated based on machine learning.
11. The imaging apparatus according to claim 1 , wherein the control unit changes the change range in which the direction of the imaging unit is changed depending on whether the information acquired by the state acquisition unit indicates a state where the imaging apparatus is placed to capture an image or a state where the imaging apparatus is held by hand.
12. The imaging apparatus according to claim 1 , wherein the control unit changes the direction of the imaging unit within the change range and performs subject searching.
13. A control method for controlling an imaging apparatus including an imaging unit configured to output image data, and one or more processors and/or circuitry, the control method comprising:
detecting a subject in the image data output by the imaging unit;
acquiring information about a holding state of the imaging apparatus among a plurality of holding states including at least one of a state where the imaging apparatus is placed to capture an image, a state where the imaging apparatus is held by a hand, a state where the imaging apparatus is hung from a neck, and a state where the imaging apparatus is wearable; and
controlling a change range in which a direction of the imaging unit is changed based on the information about the holding state of the imaging apparatus acquired in the acquiring.
14. A non-transitory computer-readable storage medium storing a program for causing a computer to execute the control method according to claim 13 .
