Photographing apparatus, and method for photographing moving object with the same
A photographing apparatus includes: an image pickup section picking up an image of an object to acquire image data; a part judgment section judging a particular part of the object in the image shown based on the image data; a change-in-part judgment section judging change over time of the part of the object judged by the part judgment section; and a control section changing a photographing condition in accordance with a result of the judgment by the change-in-part judgment section, wherein the part judgment section judges a first part of the object in the image and a second part presumed from the first part; and the change-in-part judgment section judges change over time of the second part.
1. A photographing apparatus comprising:
an image pickup section picking up an image of an object at a particular angle of view; and
control and signal processing circuits for (1) acquiring object image data based on the image of the object, (2) judging a main object in the image based on the object image data, (3) judging a position and direction of a face of the main object, (4) responsive to a determination that the face of the main object is sideways, estimating, by analysis of the object image data, a position of a second part of the main object from the judged position and direction of the face of the main object, and (5) responsive to a determination that the position of the second part of the main object cannot be estimated, judging a change of the second part, causing the image pickup section to pick up another image of the object at an angle of view wider than the particular angle of view, and acquiring object image data of the other image.
2. The photographing apparatus according to claim 1 , wherein the second part is a lower back/hip or legs.
3. The photographing apparatus according to claim 1 , wherein the control and signal processing circuits change photographing control in accordance with the judged change of the second part.
4. The photographing apparatus of claim 1 wherein the control and signal processing circuits cause the image pickup section to pick up another image of the object at an angle of view wider than the particular angle of view responsive to a prediction that the main object will make a sudden movement.
5. The photographing apparatus of claim 1 wherein the control and signal processing circuits cause the image pickup section to pick up another image of the object at an angle of view wider than the particular angle of view responsive to a prediction that the main object will make a sudden movement and at least a part of the main object will become outside of the predetermined angle of view due to the sudden movement.
6. A method for photographing a moving object, comprising the steps of:
picking up an image of an object at a particular angle of view;
acquiring object image data based on the image of the object;
judging a main object in the image based on the object image data;
judging a position and a direction of a face of the main object;
responsive to a determination that the face of the main object is sideways, estimating, by analysis of the object image data, a position of a second part of the main object from the judged position and direction of the face of the main object; and
responsive to a determination that the position of the second part of the main object cannot be estimated, judging a change of the second part, picking up another image of the object at an angle of view wider than the particular angle of view, and acquiring object image data of the other image.
7. The method of claim 6 wherein the picking up of another image of the object at an angle of view wider than the particular angle of view is responsive to a prediction that the main object will make a sudden movement.
8. The method of claim 6 wherein the picking up of another image of the object at an angle of view wider than the particular angle of view is responsive to a prediction that the main object will make a sudden movement and at least a part of the main object will become outside of the predetermined angle of view due to the sudden movement.
9. A non-transitory computer-readable storage medium storing a program for causing a computer to execute the method for photographing a moving object according to claim 6 .
