Abstract
A person is detected as a subject from an image obtained by image capture, and information, for example, the number of such subjects, is obtained as subject-related information. Then, the greater the number of subjects, the more a setting of a condition that the subjects should satisfy is relaxed. As a result, in an image processing apparatus having a function that identifies a subject state, the usability of that function that identifies the subjects can be improved even in a case in which multiple subjects are present.
Claims14
An image capturing apparatus comprising:
- an image capturing unit that generates an image;
- a detection unit that detects a face from the image;
- a determination unit that automatically changes a condition that is to be satisfied with respect to the detected faces according to information relating to the number of the detected faces and information relating to an orientation of the detected face;
- and
- a control unit that causes an image generated by said image capturing unit to be stored in a storage medium in a case where the detected faces are in a state that satisfies the condition.
An image capturing apparatus comprising:
- an image capturing unit that generates an image;
- a detection unit that detects faces from the image;
- and
- a facial expression determination unit that causes an image generated by said image capturing unit to be stored in a storage medium in a case where the detected faces are determined to have a predetermined facial expression,
- wherein said facial expression determination unit automatically relaxes a condition for determining that a detected face has the predetermined facial expression, as the number of the detected faces increases.
An image capturing apparatus comprising:
- an image capturing unit that generates an image;
- a detection unit that detects faces from the image;
- and
- a facial expression determination unit that causes an image generated by said image capturing unit to be stored in a storage medium if in a case where the detected faces are determined to have a predetermined facial expression,
- wherein said facial expression determination unit automatically relaxes a condition for determining that a detected face has the predetermined facial expression in a case where the detected face not being full front than that applied to a detected face being full front.
A control method for an image capturing apparatus having an image capturing unit that generates an image and a detection unit that detects faces from the image, the control method comprising the steps of:
- automatically changing a condition that is to be satisfied with respect to the detected faces according to information relating to the number of the detected faces and information relating to an orientation of the detected face;
- and
- causing an image generated by said image capturing unit to be stored in a storage medium in a case where the detected faces are in a state that satisfies the condition.
A control method for an image capturing apparatus having an image capturing unit that generates an image and a detection unit that detects faces from the image, the control method comprising the steps of:
- automatically relaxing a condition for determining that a detected face has the predetermined facial expression, as the number of the detected faces increases;
- and
- causing an image generated by said image capturing unit to be stored in a storage medium in a case where the detected faces are determined to have a predetermined facial expression.
A control method for an image capturing apparatus having an image capturing unit that generates an image and a detection unit that detects faces from the image, the control method comprising the steps of:
- automatically relaxing a condition for determining that a detected face has the predetermined facial expression in a case where the detected face not being full front than that applied to a detected face being full front;
- and
- causing an image generated by said image capturing unit to be stored in a storage medium in a case where the detected faces are determined to have a predetermined facial expression.
