Abstract

A photographing device includes a display unit, a movement detection unit and a display control unit. The display unit displays a preview image of being a target to photograph. The movement detection unit detects the preview image being moving from status at which the preview has been photographed as a reference photographed image. The display control unit displays a reference line on the preview image. The reference line has been set in the reference photographed image. The display control unit changes a display position and a direction of the reference line in the display unit based on a detected result by the movement detection unit.

Claims

1. A photographing device, comprising:

a display unit that displays a preview image of a target to photograph;

a movement detection unit that detects the preview image moving from a status in which the preview image has been photographed as a reference photographed image; and

a display control unit that displays a reference line on the preview image, the reference line having been set in the reference photographed image, including an edge of the reference photographed image;

wherein;

the display control unit fixedly displays a reference mark at a predetermined display position of the display unit, or

the reference mark is put on a frame of the display unit;

wherein;

the position of the reference mark is on one of;

the reference line, and

when the preview image is the same as the reference photographed image, on a virtual extended line of the reference line;

wherein the display control unit changes a display position and a direction of the reference line in the display unit so that a distance between the reference line and the reference mark corresponds to a shift quantity reflecting an amount of shill in which the preview image shifts with respect to the reference photographed image, in a direction orthogonal to the reference line, based on a result detected by the movement detection unit;

wherein the reference line is a center line of the reference photographed image;

wherein a center part of the reference line is omitted; and

wherein the center part of the reference line that is omitted is larger than the part that is shown.

2. The photographing device according to claim 1, wherein

the movement of the preview image includes at least one of a movement in a linear direction and a movement in a rotational direction, and

the display control unit changes the display position of the reference line in a direction opposite to the movement in the linear direction of the preview image and changes the direction of the reference line in a direction opposite to the movement in the rotational direction of the preview image.

3. The photographing device according to claim 1, wherein the display control unit displays the reference line in the display unit with a form in which both ends of the reference line reach an edge of a screen of the display unit.

4. The photographing device according to claim 1, wherein the display position of the reference mark is in a peripheral portion of a screen of the display unit.

5. The photographing device according to claim 1, wherein the movement detection unit detects the movement of the preview image based on a change in a display position of a predetermined image part in the display unit.

6. A photographing device, comprising:

a display means for displaying a preview image of a target to photograph;

a movement detection means for detecting the preview image moving from a status in which the preview image has been photographed as a reference photographed image; and

a display control means for displaying a reference line on the preview image, the reference line having been set in the reference photographed image, including an edge of the reference photographed image;

wherein;

the display control means fixedly displays a reference mark at a predetermined display position of the display means, or

the reference mark is put on a frame of the display means;

the position of the reference mark is on one of;

the reference line, and

when the preview image is the same as the reference photographed image, on a virtual extended line of the reference line;

the display control means changes a display position and a direction of the reference line in the display means so that a distance between the reference line and the reference mark corresponds to a shift quantity reflecting an amount of shift in which the preview image shifts to the reference photographed image, in a direction orthogonal to the reference line, based on a result detected by the movement detection means;

the reference line is a center line of the reference photographed image;

a center part of the reference line is omitted; and

wherein the center part of the reference line that is omitted is lamer than the part that is shown.

7. A display method for a photographing device, comprising:

detecting a movement of a preview image, of a target to photograph, from a status in which the preview image has been photographed as a reference photographed image;

displaying a reference line on the preview image, the reference line having been set in the reference photographed image, including an edge of the reference photographed image; and

fixedly displaying a reference mark at a predetermined display position of a display, or putting the reference mark on a frame of the display;

wherein;

the position of the reference mark is on one of;

the reference line, and

when the preview image is the same as the reference photographed image, on a virtual extended line of the reference line; and

a display position and a direction of the reference line is changed so that a distance between the reference line and the reference mark corresponds to a shift quantity reflecting an amount of shift in which the preview image shifts to the reference photographed image, in a direction orthogonal to the reference line, based on the detecting of the movement of the preview image;

the reference line is a center line of the reference photographed image;

a center part of the reference line is omitted; and

wherein the center part of the reference line that is omitted is lamer than the part that is shown.
