Abstract
There is disclosed an imaging apparatus for displaying a live view image, in which an enlargement ratio of the live view image dynamically changes according to changes in in-focus state of a subject.
Claims9
An imaging apparatus for imaging a subject, comprising:
- a shooting optical system for forming an image of a light beam from the subject;
- an imaging part for capturing images of the subject at predetermined intervals to output a moving image;
- a display part for displaying, on a display, the moving image output from the imaging part as a live picture;
- a focus adjusting part for changing a focus position of the shooting optical system in accordance with an operation performed by a user;
- a display control part for deciding an enlargement ratio of the live picture to be displayed on the display by the display part;
- and
- an in-focus evaluation value calculating part for calculating an in-focus evaluation value indicating an in-focus level of each frame of the moving image output from the imaging part,
- wherein the display control part decides the enlargement ratio of the live picture to be displayed on the display based on the in-focus evaluation value.

An imaging apparatus comprising:
- an image pickup device;
- a shooting optical system for forming an image of light from a subject on the image pickup device and capable of performing a manual focus operation;
- an image processing controller for processing electric signals output from the image pickup device at predetermined intervals to output a moving image;
- a computer for detecting, in a portion of each frame of the moving image, a change in in-focus state of the imaging optical system in response to the manual focus operation to zoom in the moving image at an enlargement ratio successively changed with changes in the in-focus state;
- and
- a monitor for displaying the zoomed-in moving image.

A live view display method for displaying a live view image on a display of a camera comprising;
- capturing images, which is formed by a shooting optical system of the camera, at predetermined intervals to output as a moving image;
- moving a focus position of the shooting optical system that is changed in accordance with an operation performed by a user;
- calculating an in-focus value indicating an in-focus state of each frame of the moving image;
- creating a live picture from the moving image by trimming or resizing each frame of the moving image at an enlargement ratio according to the calculated in-focus value;
- and
- displaying the created live picture on the display.
