Abstract
Disclosed is a digital still camera in which focusing can be checked easily even if a display device constituting the viewfinder is comparatively small. When a shutter-release button is pressed half-way, focusing is performed and the image in a focusing zone is made larger than the part of an angle-of-view confirmation image that corresponds to the focusing zone. An in-focus confirmation image of the enlarged focusing zone is displayed on the display screen of the viewfinder. When focusing is performed, the in-focus confirmation image is enlarged in comparison with the corresponding area of the angle-of-view confirmation image. This makes it easier to determine whether an image is in focus or not.
Claims8
An image sensing apparatus having an image sensing unit for sensing the image of a subject via a focusing lens and outputting a video signal representing the image of the subject formed on a photoreceptor surface, a focus control unit for controlling the focusing lens in such a manner that an image within a focusing zone is focused on the photoreceptor surface, and a first display device for displaying the image of the subject, which is for confirming angle of view, represented by the video signal output from the image sensing unit, said apparatus comprising:
- an enlargement unit for applying enlargement processing to the video signal, which has been output from the image sensing unit, in such a manner that an in-focus confirmation image, which corresponds to the focusing zone, in the image of the subject for confirming angle of view is enlarged in comparison with the image of the subject for confirming the angle of view;
- and
- a second display device for displaying the in-focus confirmation image enlarged by said enlargement unit.
A method of controlling operation of an image sensing apparatus an image sensing unit for sensing the image of a subject via a focusing lens and outputting a video signal representing the image of the subject formed on a photoreceptor surface, a focus control unit for controlling the focusing lens in such a manner that an image within a focusing zone is focused on the photoreceptor surface, and a first display device for displaying the image of the subject, which is for confirming angle of view, represented by the video signal output from the image sensing unit, the method comprising the steps of:
- applying enlargement processing to the video signal, which has been output from the image sensing unit, in such a manner that an in-focus confirmation image, which corresponds to the focusing zone, in the image of the subject for confirming angle of view is enlarged in comparison with the image of the subject for confirming angle of view;
- and
- displaying the in-focus confirmation image that has been enlarged.
