Image-taking apparatus, image-taking region displaying method, and image-taking region displaying program

An image-taking apparatus comprising:

• an image recording range extracting unit that extracts an image corresponding to a first image-taking region having a predetermined first aspect ratio and an image corresponding to a second image-taking region having a predetermined second aspect ratio from a video image of a subject of an image-taking target to record the image corresponding to the first image-taking region and the image corresponding to the second image-taking region, the second aspect ratio being different from the first aspect ratio;
• an image display range extracting unit that extracts an image having an aspect ratio of a display region of a display device from the video image of the subject of the image-taking target in a range where the first image-taking region is maximally displayed, the display device displaying the images corresponding to the first image-taking region and the second image-taking region;
• a region notification image producing unit that produces a region notification image indicating that the second image-taking region exists outside the display region of the display device when the second image-taking region exists outside the region of the image extracted by the image display range extracting unit;
• an image combining unit that produces a display image by combining the region notification image produced by the region notification image producing unit with the image extracted by the image display range extracting unit;
• and
• a display control unit that displays the display image produced by the image combining unit on the display device,
• wherein the region notification image producing unit produces the region notification image including a region notification icon, indicating a direction of the second image-taking region existing outside the display region of the display device,
• wherein the region notification image producing unit produces the region notification image including a guide frame indicating a boundary of the second image-taking region when part of the boundary of the second image-taking region exists in the display region of the display device, the guide frame,
• wherein a combination of the first aspect ratio and the second aspect ratio is an aspect ratio that is arbitrarily selected by a user,
• wherein a combination of the first aspect ratio and the second aspect ratio is automatically switched according to an image-taking mode selected by the user, and
• wherein the region notification image producing unit produces a region notification image that is different from a region notification image in a state in which the image recording range extracting unit does not record the image corresponding to the second image-taking region, when the image recording range extracting unit is recording the image corresponding to the second image-taking region.
