Imaging apparatus for changing field angle according to apparatus movement
First Claim
Patent Images
1. An imaging apparatus comprising:
- an imaging unit which comprises a lens that forms an image of a subject and which is configured to acquire a picture image by taking the image formed by the lens;
a field angle change unit configured to change a field angle of the lens; and
a movement detection unit configured to detect a movement of the imaging apparatus,wherein the field angle change unit changes the field angle of the lens to a wide-angle side when the moving direction of the imaging apparatus is a direction along which the lens moves away from the subject or when a wide-switch is operated manually, andwherein the field angle change unit automatically changes the field angle of the lens to a telephotographic side, without manual tele-switch operation, after driving the lens toward a wide-angle side due to movement of the imaging apparatus away from the subject.

Abstract
An imaging apparatus includes an imaging unit, a field angle change unit, and a movement detection unit. The imaging unit includes a lens that forms an image of a subject and acquires a picture image by taking the image formed by the lens. The field angle change unit changes a field angle of the picture image acquired by the imaging unit. The movement detection unit detects a movement of the imaging apparatus. The field angle change unit changes the field angle of the picture image in accordance with a moving direction of the imaging apparatus when the movement detection unit detects the movement of the imaging apparatus.

18. A computer-implemented method for use with an imaging apparatus, the computer-implemented method comprising:
-
forming, with a lens of the imaging apparatus, an image of a subject; acquiring, with an imaging unit of the imaging apparatus, a picture image by taking the image formed by the lens; detecting a movement of the imaging apparatus; changing a field angle of the lens to a wide-angle side when a detected movement of the imaging apparatus is in a direction along which the lens moves away from the subject or when a wide-switch is operated manually; and automatically changing the field angle of the lens to a telephotographic side, without manual tele-switch operation, after driving the lens toward a wide-angle side due to movement of the imaging apparatus away from the subject.
