Imaging device, imaging method, and program
The present technology relates to an imaging device, an imaging method, and a program that make it possible to easily perform imaging focusing on a subject or a specific part of the subject. The imaging device causes a preliminary-notice frame that gives notice of a specific area to be focused to be displayed on an image obtained by an imaging unit according to a type of the subject. The present technology can be applied to an imaging device.
1. An imaging device comprising:
memory configured to:
store, when the memory receives an image from an imaging unit, the image from the group consisting of a moving image and a still image,
a subject area detection unit configured to:
detect, in the image when the subject area detection unit receives the image from the memory, a subject area, and
detect, when the subject area detection unit detects the subject area, a specific part within the subject area, and
a display control unit configured to:
control, before the subject area detection unit detects the subject area, a display unit to display the image on a display screen,
control, when the subject area detection unit detects the subject area, the display unit to superimpose a preliminary-notice frame on the display screen so that the preliminary-notice frame surrounds the subject area on the display screen, and
control, when the display control unit replaces the preliminary-notice frame with a specific part frame, the display unit to superimpose the specific part frame on the display screen so that the specific part frame surrounds the specific part on the display screen.
2. The imaging device according to claim 1 , wherein a digital signal processing unit is comprised of:
the subject area detection unit,
the display control unit, and
the memory.
3. The imaging device according to claim 1 , further comprising:
a display unit configured to display, when the display control unit superimposes the preliminary-notice frame onto the image, the image on the display screen.
4. The imaging device according to claim 3 , wherein the display unit is configured to display, when the display control unit superimposes the specific part frame onto the image, the image on the display screen.
5. The imaging device according to claim 1 , further comprising:
an area setting unit configured to receive, from the subject area detection unit when the subject area detection unit detects the specific part, the specific part.
6. The imaging device according to claim 5 , wherein the area setting unit is configured to set, when the area setting unit receives the specific part, the specific part as a focus area.
7. The imaging device according to claim 6 , wherein the display unit is configured to replace, when the area setting unit sets the specific part, the preliminary-notice frame with the specific part frame.
8. The imaging device according to claim 6 , wherein the display control unit is configured to superimpose the preliminary-notice frame before the area setting unit sets the specific part.
9. The imaging device according to claim 6 , further comprising:
a controller configured to control an imaging unit to perform focusing in the focus area to obtain the image.
10. The imaging device according to claim 1 , wherein the display control unit is configured to generate, for display on the display screen with the image, a graphical user interface.
11. The imaging device according to claim 1 , further comprising:
a codec processing unit configured to encode and decode the image.
12. An imaging method comprising:
storing, by memory when the memory receives an image from an imaging unit, the image from the group consisting of a moving image and a still image;
detecting, by a subject area detection unit when the subject area detection unit receives the image from the memory, a subject area in the image;
detecting, by the subject area detection unit when the subject area detection unit detects the subject area, a specific part within the subject area;
controlling, by a display control unit before the subject area detection unit detects the subject area, a display unit to display the image on a display screen;
controlling, by the display control unit when the subject area detection unit detects the subject area, the display unit to superimpose a preliminary-notice frame on the display screen so that the preliminary-notice frame surrounds the subject area on the display screen; and
controlling, by the display control unit when the display control unit replaces the preliminary-notice frame with a specific part frame, the display unit to superimpose the specific part frame on the display screen so that the specific part frame surrounds the specific part on the display screen.
13. The imaging method according to claim 12 , further comprising:
receiving, by an area setting unit from the subject area detection unit when the subject area detection unit detects the specific part, the specific part.
14. The imaging method according to claim 13 , further comprising:
setting, by the area setting unit when the area setting unit receives the specific part, the specific part as a focus area.
15. The imaging method according to claim 14 , further comprising:
controlling, by a controller, an imaging unit to perform focusing in the focus area to obtain the image.
16. The imaging method according to claim 14 , further comprising:
replacing, by the display unit is when the area setting unit sets the specific part, the preliminary-notice frame with the specific part frame.
17. The imaging method according to claim 14 , further comprising:
superimposing, by the display control unit, the preliminary-notice frame before the area setting unit sets the specific part.
18. The imaging method according to claim 12 , further comprising:
encoding and decoding, by a codec processing unit, the image.
19. A non-transitory computer-readable recording medium comprising a program, the program causing an imaging device to execute the imaging method according to claim 12 .
