Imaging method using multifocal lens
First Claim
1. An imaging method using a multifocal lens having a plurality of regions, the plurality of regions having different focal lengths, the method comprising:
- controlling a focusing state of the multifocal lens;
obtaining an image of a subject in the controlled focusing state; and
calculating required focusing times required for focusing at each of the respective regions,wherein in the controlling the focusing state, the focusing state is controlled so that a main subject is focused via a region with a shortest required focusing time of the calculated required focusing times among the plurality of regions in response to input of a picture taking instruction.

Abstract
An aspect of the present invention is an imaging method using a multifocal lens having a plurality of regions, the plurality of regions having different focal lengths, and the imaging method includes a focusing state control step of controlling a focusing state of the multifocal lens, and an imaging step of obtaining an image of a subject in the controlled focusing state. In the focusing state control step, the focusing state is controlled so that a main subject is focused via a region with a shortest required focusing time among the plurality of regions in response to a picture taking instruction.

12. An imaging method using a multifocal lens having a plurality of regions, the plurality of regions having different focal lengths, the method comprising:
-
controlling a focusing state of the multifocal lens; obtaining an image of a subject in the controlled focusing state; and calculating required focusing times required for focusing at each of the respective regions, wherein in response to input of a picture-taking instruction, a first imaging is continuously performed, a second imaging is continuously performed subsequent to the first imaging, and a moving image of the subject is obtained when a region with a shortest required focusing time of the calculated required focusing times among the plurality of regions is not a main region having a largest area among the plurality of regions, otherwise, in response to the input of the picture-taking instruction, the first imaging is continuously performed to obtain the moving image of the subject, in the first imaging, control is performed so that a main subject is focused via the region with the shortest required focusing time in the focusing state control to obtain an image of the subject, and in the second imaging, control is performed so that the main subject is focused via the main region in the focusing state control to obtain the image of the subject. - View Dependent Claims (13, 14, 15)
