Abstract

A finder is configured to be capable of observing a subject image through a finder lens. A finder information display section performs display of information in a state where the information is superimposed on the subject image, and displays first to third angle-of-view frames. The first angle-of-view frames are a plurality of angle-of-view frames corresponding to the focal lengths of all the imaging lenses mountable on the mount section. The second angle-of-view frames are a plurality of angle-of-view frames corresponding to the focal lengths of the imaging lenses previously mounted on the mount section. The third angle-of-view frame is an angle-of-view frame corresponding to the focal length of the imaging lens mounted on the mount section. By displaying the angle-of-view frames of all the imaging lenses mountable on the mount section, it is possible to easily find an imaging lens having the optimum focal length for the captured scene.

Dependent claims

An imaging device comprising:

a mount section on which a plurality of imaging lenses having different focal lengths are detachably mounted;
an imaging element that generates an image on the basis of a subject image incident through one of the imaging lenses mounted on the mount section;
a finder that is configured to be capable of observing the subject image through a finder lens;
a finder information display section that performs display so as to be capable of observing information in a state where the information is superimposed on the subject image, in the finder;
a mounting history storage section that stores a mounting history of the imaging lens previously mounted on the mount section;
a first angle-of-view frame display control section that controls the finder information display section such that the finder information display section displays, as the information, a plurality of first angle-of-view frames corresponding to the focal lengths of all the imaging lenses mountable on the mount section;
a second angle-of-view frame display control section that controls the finder information display section and sets one of the plurality of first angle-of-view frames, which corresponds to the focal length of the imaging lens previously mounted on the mount section, as a second angle-of-view frame on the basis of the mounting history, such that the finder information display section displays, as the information, the second angle-of-view frame in a display form different from a display form of the first angle-of-view frame;
and
a third angle-of-view frame display control section controls the finder information display section such that the finder information display section displays, as the information, a third angle-of-view frame, which corresponds to the focal length of the imaging lens currently mounted on the mount section, in a display form different from the display forms of the first and second angle-of-view frames.

an imaging element that generates an image on the basis of a subject image incident through one of the imaging lenses mounted on the mount section,
a finder that is configured to be capable of observing the subject image through a finder lens, and
a finder information display section that performs display so as to be capable of observing information in a state where the information is superimposed on the subject image, in the finder,
the control method comprising:
a mounting history storing step of storing a mounting history of the imaging lens previously mounted on the mount section;
a first angle-of-view frame display control step of controlling the finder information display section such that the finder information display section displays, as the information, a plurality of first angle-of-view frames corresponding to the focal lengths of all the imaging lenses mountable on the mount section;
a second angle-of-view frame display control step of controlling the finder information display section and setting one of the plurality of first angle-of-view frames, which corresponds to the focal length of the imaging lens previously mounted on the mount section, as a second angle-of-view frame on the basis of the mounting history, such that the finder information display section displays, as the information, the second angle-of-view frame in a display form different from a display form of the first angle-of-view frame;
and
a third angle-of-view frame display control step of controlling the finder information display section such that the finder information display section displays, as the information, a third angle-of-view frame, which corresponds to the focal length of the imaging lens currently mounted on the mount section, in a display form different from the display forms of the first and second angle-of-view frames.
