Image pick-up apparatus and control method thereof
An image pick-up apparatus acquires a photographing distance and calculates angle information on the basis of a detection result of a motion vector in a panning state and a photographing distance. The image pick-up apparatus performs automatic photographing when the calculated angle information is a predetermined angle.
1. An image pick-up apparatus comprising:
a memory;
one or more processors, wherein the processor functions as the following units according to a program stored in the memory:
(1) a vector detection unit configured to detect a motion vector on the basis of a captured image;
(2) an acquisition unit configured to acquire a photographing distance;
(3) a selection unit configured to select a plurality of predetermined angles;
(4) a calculator configured to calculate angle information on the basis of a detection result of the motion vector in a panning state and the photographing distance; and
(5) a photographing controller configured to perform automatic photographing every time angle information calculated by the calculator represents each of the selected predetermined angles.
2. The image pick-up apparatus according to claim 1 , wherein the calculator calculates the angle information on the basis of the photographing distance and an amount of motion of the subject acquired on the basis of the detection result of the motion vector.
3. The image pick-up apparatus according to claim 1 , wherein the processor further functions as:
a shake correction unit used for correcting image blur associated with the subject caused by shaking applied to the image pick-up apparatus; and
a shake correction controller configured to control the shake correction unit on the basis of a subject angular velocity obtained from a detection result of the motion vector.
4. The image pick-up apparatus according to claim 1 , wherein the selection unit selects the predetermined angles in accordance with a user's operation.
5. The image pick-up apparatus according to claim 1 , wherein the processor further functions as a display control unit which displays a composition according to the predetermined angles on a display unit.
6. A method for controlling an image pick-up apparatus comprising:
detecting a motion vector on the basis of a captured image;
acquiring a photographing distance;
calculating angle information on the basis of a detection result of the motion vector in a panning state and the photographing distance;
selecting a plurality of predetermined angles; and
performing automatic photographing every time the calculated angle information represents each of the selected predetermined angles.
