## Abstract

An electronic apparatus includes first and second cameras having the same imaging direction, display device, and control device. The control device performs an imaging area display operation to cause the display device to display an imaging area of the second camera in overlay on an image captured by the first camera.

## Claims

### Claim 1

An electronic apparatus comprising:
a first camera and a second camera, having a same photographing direction from the electronic apparatus;
a display device that displays an image captured by the first camera;
a touch panel; and
a control device,
wherein the control device performs an imaging area display operation,
to cause the display device to display an imaging area of the second camera in overlay on the image captured by the first camera,
further to cause the display device to display, a zoom operation bar capable of changing a zoom magnification of the second camera by inputting to the touch panel, the zoom operation bar overlaid on the image captured by the first camera, and
to cause a size of the imaging area of the second camera displayed on the display device to change according to a change of the zoom magnification of the second camera.

### Claim 2 (depends on 1)

The electronic apparatus according to claim 1, wherein the imaging area display operation maintains a display size of the imaging area of the first camera even if a size of the imaging area of the second camera is changed in response to a position of the imaging area of the second camera and/or zooming of the second camera.

### Claim 3 (depends on 1)

The electronic apparatus according to claim 1, wherein the control device performs a coordinate conversion operation to acquire first area information in accordance with information on a difference between a view angle of the first camera and a view angle of the second camera.

### Claim 4 (depends on 1)

The electronic apparatus according to claim 1, wherein the control device performs a coordinate conversion operation to acquire first area information in accordance with information on a difference between an optical axis of the first camera and an optical axis of the second camera.

### Claim 5 (depends on 1)

The electronic apparatus according to claim 1, wherein the imaging area display operation displays as a frame an area based on first area information.

### Claim 6 (depends on 1)

The electronic apparatus according to claim 1, wherein the first camera captures a video while the second camera captures a still image.

### Claim 7 (depends on 1)

The electronic apparatus according to claim 1, wherein if at least part of an area based on second area information includes coordinates outside a second coordinate system, the control device performs a coordinate conversion operation to correct a center position of the imaging area of the second camera such that the second area information is included in the second coordinate system.

### Claim 8

A control device controlling an electronic apparatus including a touch panel,
a first camera and a second camera, having a same photographing direction from the electronic apparatus, and
a display device displaying an image captured by the first camera,
the control device comprising an imaging area display unit that
causes the display device to display an imaging area of the second camera in overlay on the image captured by the first camera,
further causes the display device to display, a zoom operation bar capable of changing a zoom magnification of the second camera by inputting to the touch panel, the zoom operation bar overlaid on the image captured by the first camera, and
causes a size of the imaging area of the second camera displayed on the display device to change according to a change of the zoom magnification of the second camera.

### Claim 9

A method of controlling an electronic apparatus including a touch panel,
a first camera and a second camera, having a same photographing direction from the electronic apparatus, and
a display device displaying an image captured by the first camera,
the method comprising:
causing the display device to display an imaging area of the second camera in overlay on the image captured by the first camera;
further causing the display device to display, a zoom operation bar capable of changing a zoom magnification of the second camera by inputting to the touch panel, the zoom operation bar overlaid on the image captured by the first camera; and
causing a size of the imaging area of the second camera displayed on the display device to change according to a change of the zoom magnification of the second camera.

### Claim 10 (depends on 1)

The electronic apparatus according to claim 1, wherein the zoom operation bar extends along one of sides of the display device.

### Claim 11 (depends on 1)

The electronic apparatus according to claim 1, wherein the zoom operation bar extends along one side of the display device, and the zoom magnification of the second camera is lower toward one end of the zoom operation bar and higher toward the other end of the zoom operation bar.

### Claim 12 (depends on 1)

The electronic apparatus according to claim 1, wherein the imaging area of the second camera is displayed as a translucently painted rectangle on the display device.
