Abstract
An imaging method includes imaging light from an object passed through an imaging optical system to acquire a taken image, changing an imaging magnification of the imaging optical system, and switching a finder magnification of a finder optical system different from the imaging optical system from a first finder magnification to a second finder magnification when the imaging magnification increases and switching the finder magnification from the second finder magnification to the first finder magnification when the imaging magnification decreases.
Claims9
An imaging device comprising:
- an imaging unit configured to image light from an object passed through an imaging optical system to acquire a taken image;
- a zooming unit configured to continuously change an imaging magnification of the imaging optical system;
- an optical finder configured to observe an image of the object via a finder optical system different from the imaging optical system;
- a magnification varying unit configured to switch a finder magnification, which is a magnification of the finder optical system, from a first finder magnification to a second finder magnification when the imaging magnification increases to a first imaging magnification and switch the finder magnification from the second finder magnification to the first finder magnification when the imaging magnification decreases to a second imaging magnification smaller than the first imaging magnification;
- and
- a determining unit configured to determine whether the magnification of the taken image is not changed for a predetermined time after the magnification of the taken image is changed to the first imaging magnification or the second imaging magnification by the zooming unit,
- wherein the magnification varying unit changes the finder magnification when the determining unit determines that the magnification of the taken image is not changed for the predetermined time.
