Abstract
An imaging device includes an imaging lens, an image sensor to output an image signal in accordance with an image of a subject captured via the imaging lens, a lens driver to move the imaging lens, an autofocus detector to determine a focal point according to image data obtained from the image signal, a point source detector to determine whether or not a subject is a point source subject on the basis of a brightness component included in the image data, and a driving mode setter to change a driving condition of the image sensor when the subject is determined to be a point source subject.
Claims6
An imaging device comprising:
- an imaging lens;
- an image sensor to output an image signal in accordance with an image of a subject captured via the imaging lens;
- a lens driver to move the imaging lens;
- an autofocus detector to determine a focal point according to image data obtained from the image signal;
- a point source detector to determine whether or not a subject is a point source subject on the basis of a brightness component included in the image data;
- and
- a driving mode setter to change a driving condition of the image sensor when the subject is determined to be a point source subject.
An imaging method comprising the steps of:
- capturing an image of a subject;
- outputting an image signal in accordance with the captured subject image;
- determining a focal point according to image data obtained from the image signal;
- determining whether or not a subject is a point source subject on the basis of a brightness component included in the image data;
- and
- changing a driving condition of an image sensor when the subject is determined to be a point source subject.
