Abstract

In an operation of a GUI member, operation feeling as if a user is operating a real object is realized. An imaging unit captures fingers of an operator. A system control unit detects the finger portion from the image captured by the imaging unit. The system control unit combines images in such a manner that the GUI member is positioned on a finger portion of a palm side and a finger portion of a backside is positioned on the GUI member from the image of the finger portions detected from the captured image, and displays the combined image on a display unit.

Claims

1. An imaging apparatus comprising:

an imaging unit;

a detection unit configured to detect finger portions from an image captured by the imaging unit; and

a display control unit configured to display, on a display unit, a combined image generated in such a manner that a GUI member is positioned on a finger portion of a palm side and a finger portion of a back side is positioned on the GUI member from the image of the finger portions detected by the detection unit.

2. The imaging apparatus according to claim 1, further comprising:

an estimation unit configured to estimate that there are the finger portions within an image capturing area of the imaging unit; and

a determination unit configured to determine that a user points the GUI member displayed on an overlapped portion of the finger portion on the palm side and the finger portion of the back side in the portion of the fingers estimated by the estimation unit.

3. The imaging apparatus according to claim 1, further comprising:

an estimation unit configured to estimate that the finger portion is included in a image capturing area of the imaging unit;

a nail detection unit configured to detect a nail portion of the finger portion from the image captured by the imaging unit; and

a determination unit configured to determine that a user points the GUI member displayed on an overlapped portion of the finger portion of the palm side and the nail portion of a thumb detected by the nail detection unit from the finger portions estimated by the estimation unit.

4. The imaging apparatus according to claim 2, wherein, when the determination unit determines that the user points the GUI member and the finger portion detected by the detection unit is enlarged or reduced, the display control unit displays the GUI member to be enlarged or reduced according to the finger portion.

5. The imaging apparatus according to claim 2, wherein, when the determination unit determines that the user points the GUI member, the display control unit displays the GUI member with a similar focusing level to that of the finger portion.

6. A control method for an imaging apparatus, comprising:

detecting a finger portions from an image captured by an imaging unit;

combining images generated in such a manner that a GUI member is positioned on a finger portion of a palm side and the finger portion of a back side on the GUI member from the image of the finger portions detected by the detection; and

displaying the combined image on a display unit.

7. A non-transitory recording medium that records a control program for controlling an imaging apparatus, the control program comprising:

detecting a finger portion from an image captured by the imaging apparatus;

generating a combined image such that a GUI member is positioned on a finger portion of the palm side and a finger portion of the back side is positioned on the GUI member from an image of the detected finger portions; and

displaying the combined image on a display unit.
