Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
230 words
An image capturing apparatus, comprising: an image sensing unit configured to sense an image of a subject; an image data conversion unit configured to convert the image of the subject from the image sensing unit to an angle-of-view confirmation image and configured to convert a focusing zone of the image of the subject from the image sensing unit to an in-focus confirmation image; a focusing zone image data conversion unit configured to convert the image of the subject from the image sensing unit to the in-focus confirmation image; a focusing zone storage device configured to store the in-focus confirmation image from the focusing zone image data conversion unit; a temporary storage device configured to store the angle-of-view confirmation image and the in-focus confirmation image from the image data conversion unit; a display unit configured to display one or both of the angle-of-view confirmation image and the in-focus confirmation image retrieved from the temporary storage; and a controller configured to control the display unit to display the one or both of the angle-of-view confirmation image and the in-focus confirmation image, wherein a magnification of the in-focus confirmation image is greater than a magnification of the angle-of-view confirmation image, and wherein the temporary storage device is configured to store the angle-of-view confirmation image from the image data conversion unit and to store the in-focus confirmation image from the focusing zone storage device.
Claim 2
Dependent Claim
230 words
An image capturing apparatus, comprising: an image sensing unit configured to sense an image of a subject; an image data conversion unit configured to convert the image of the subject from the image sensing unit to an angle-of-view confirmation image and configured to convert a focusing zone of the image of the subject from the image sensing unit to an in-focus confirmation image; a focusing zone image data conversion unit configured to convert the image of the subject from the image sensing unit to the in-focus confirmation image; a focusing zone storage device configured to store the in-focus confirmation image from the focusing zone image data conversion unit; a temporary storage device configured to store the angle-of-view confirmation image and the in-focus confirmation image from the image data conversion unit; a display unit configured to display one or both of the angle-of-view confirmation image and the in-focus confirmation image retrieved from the temporary storage; and a controller configured to control the display unit to display the one or both of the angle-of-view confirmation image and the in-focus confirmation image, wherein a magnification of the in-focus confirmation image is greater than a magnification of the angle-of-view confirmation image, and wherein the temporary storage device is configured to store the angle-of-view confirmation image from the image data conversion unit and to store the in-focus confirmation image from the focusing zone storage device.
Claim 3
Dependent Claim
30 words
The image capturing apparatus of claim 1 , wherein an area of the focusing zone is dynamically selectable anywhere within the image of the subject based on a user input.
Claim 4
Dependent Claim
24 words
The image capturing apparatus of claim 1 , wherein the magnification of the in-focus confirmation image is dynamically selectable based on a user input.
Claim 5
Dependent Claim
57 words
The image capturing apparatus according to claim 1 , wherein the temporary storage device includes a first image memory and a second image memory, wherein both the first and second memories are each capable of storing the angle-of-view confirmation image, and wherein both the first and second memories are each capable of storing the in-focus confirmation image.
Claim 6
Dependent Claim
27 words
The image capturing apparatus according to claim 1 , wherein the controller is configured to display the in-focus confirmation image on an entirety of the display unit.
Claim 7
Dependent Claim
28 words
The image capturing apparatus according to claim 1 , wherein the controller is configured to superimpose the in-focus confirmation image over the angle-view-confirmation image on the display unit.
Claim 8
Dependent Claim
32 words
The image capturing apparatus according to claim 1 , wherein both the angle-of-view confirmation image and the in-focus confirmation image are derived from a single frame of the image of the subject.
Claim 9
Dependent Claim
20 words
The image capturing apparatus according to claim 1 , wherein the image capturing apparatus is a still image capturing apparatus.
