Abstract

A device having an imaging function includes: a camera portion to capture optically an image of an object and to output the image as an image data; a display portion to perform an image displaying using the image data from the camera portion; and a control portion to decide a representative figure by extracting features of the image from the image data of a whole photographed screen and to control the display portion so that if a position of the representative figure is changed, the display portion performs an image displaying to which a process corresponding to the change is applied.

Claims

1. A device having an imaging function, comprising:

a camera portion to capture optically an image of an object and to output the image as an image data;

a display portion to perform an image displaying using the image data from the camera portion; and

a control portion to decide a representative figure by extracting features of the image from the image data of a whole photographed screen and to control the display portion so that if a position of the representative figure is changed, the display portion performs an image displaying to which a process corresponding to the change is applied.

2. The device according to claim 1, further comprising an operation portion to designate a prescribed part in the photographed screen as a covered area to cover the part, wherein the control portion controls the display portion so that the display portion does not perform an image displaying using the image data in the covered area which is designated by the operation portion.

3. The device according to claim 2, wherein the process corresponding to the change is a process to move the covered area in order not to change a relative position of the covered area with respect to the representative figure.

4. The device according to claim 2, wherein the process corresponding to the change is a process to select an area of a trajectory as a new covered area when the covered area is moved in order not to change the relative position of the covered area with respect to the representative figure.

5. The device according to claim 2, further comprising a memory portion to memorize at least one of the covered area and the representative figure.

6. The device according to claim 1, wherein the control portion calculates a variation of the position of the representative figure.

7. The device according to claim 6, further comprising a reporting portion to perform a reporting to outside of the device, wherein the control portion controls the reporting portion so that the reporting portion reports the change of the device position if the variation is over a prescribed value.

8. The device according to claim 3, further comprising a memory portion to memorize at least one of the covered area and the representative figure.

9. The device according to claim 8, wherein the control portion calculates a variation of the position of the representative figure.

10. The device according to claim 9, further comprising a reporting portion to perform a reporting to outside of the device, wherein the control portion controls the reporting portion so that the reporting portion reports the change of the device position if the variation is over a prescribed value.

11. The device according to claim 4, further comprising a memory portion to memorize at least one of the covered area and the representative figure.

12. The device according to claim 11, wherein the control portion calculates a variation of the position of the representative figure.

13. The device according to claim 12, further comprising a reporting portion to perform a reporting to outside of the device, wherein the control portion controls the reporting portion so that the reporting portion reports the change of the device position if the variation is over a prescribed value.

14. The device according to claim 3, wherein the control portion calculates a variation of the position of the representative figure.

15. The device according to claim 14, further comprising a reporting portion to perform a reporting to outside of the device, wherein the control portion controls the reporting portion so that the reporting portion reports the change of the device position if the variation is over a prescribed value.

16. The device according to claim 4, wherein the control portion calculates a variation of the position of the representative figure.

17. The device according to claim 16, further comprising a reporting portion to perform a reporting to outside of the device, wherein the control portion controls the reporting portion so that the reporting portion reports the change of the device position if the variation is over a prescribed value.

18. A device having an imaging function, comprising:

a camera portion to capture optically an image of an object and to output the image as an image data;

a display portion to perform an image displaying using the image data from the camera portion;

an operation portion to designate a prescribed part in a photographed screen as a covered area to cover the part;

a control portion to control the display portion so that the display portion does not perform an image displaying using the image data in the covered area which is designated by the operation portion and to decide a representative figure by extracting features of the image from the image data of the whole photographed screen; and

a memory portion to memorize at least one of the covered area and the representative figure, wherein

if a position of the representative figure is changed, the control portion controls the display portion so that the display portion performs an image displaying to which a process is applied to move the covered area in order not to change a relative position of the covered area with respect to the representative figure based on a calculated result of the variation of the position of the representative figure, or

if the position of the representative figure is changed while the covered area before the movement is in contact with an edge of the photographed screen, the control portion controls the display portion so that the display portion performs an image displaying to which a process is applied to select an area of a trajectory as a new covered area when the covered area is moved in order not to change the relative position of the covered area with respect to the representative figure based on the calculated result of the variation of the position of the representative figure.

19. A device having an imaging function, comprising:

a camera portion to capture optically an image of an object and to output the image as an image data;

a display portion to perform an image displaying using the image data from the camera portion;

a reporting portion to perform a reporting to outside of the device; and

a control portion to decide a representative figure by extracting features of the image from the image data of a whole photographed screen and to control the reporting portion to report a change of a position of the device if the position of the representative figure is changed over a prescribed value.
