Abstract

A GUI member is operated to let a user feel as if operation of 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 back side 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:

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

a display control unit configured to display, on a display unit, an image in which a GUI member is positioned on a finger portion detected by the detection unit on a palm side and a finger portion detected by the detection unit on a back side is positioned on the GUI member,

wherein the display control unit is configured to, in a case where the detection unit detects the finger portion being enlarged or reduced, display the GUI member to be enlarged or reduced according to enlargement or reduction of the finger portion.

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

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

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 the finger portion detected by the nail detection unit.

4. The imaging apparatus according to claim 1, wherein the display control unit is configured to, in a case where the determination unit determines that the user points the GUI member, display the GUI member with a similar focusing level to that of the finger portion.

5. A display control method for a display apparatus, the display control method comprising:

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

controlling display to display, on a display unit, an image in which a GUI member is positioned on a finger portion on a palm side and a finger portion on aback side is positioned on the GUI member from the image of the finger portions detected by the detection,

wherein, in a case where the finger portion being enlarged or reduced is detected, the GUI member is enlarged or reduced according to enlargement or reduction of the finger portion and displayed.

6. The display control method according to claim 5, further comprising determining 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.

7. The display control method according to claim 5, further comprising:

detecting a nail portion of the finger portion from the image captured by the imaging unit; and

determining that a user points the GUI member displayed on an overlapped portion of the finger portion of the palm side and the detected nail portion of the finger portion.

8. The display control method according to claim 5, wherein, in a case where it is determined that the user points the GUI member, the GUI member is displayed with a similar focusing level to that of the finger portion.

9. The non-transitory computer-readable storage medium for allowing a display apparatus to execute steps according to claim 6.
