Photographing device including face recognition, distance calculation, and distance comparison units and method of controlling the same
View Patent ↗A photographing device for photographing a subject is provided. The photographing device includes a face recognition unit recognizing a face included in an image of the subject; a distance calculation unit calculating a distance between each of a plurality of faces when the plurality of faces are recognized by the face recognition unit; and a distance comparison unit comparing the distance calculated by the distance calculation unit with a pre-set reference distance. A of controlling the photographing device is also provided.
1. A photographing device photographing a subject, the photographing device configured to be operable in a specific mode and comprising:
a face recognition unit recognizing a face included in an image of the subject;
a distance calculation unit calculating a distance between each of a plurality of faces when the plurality of faces are recognized by the face recognition unit; and
a distance comparison unit comparing the distance calculated by the distance calculation unit with a pre-set reference distance,
wherein the distance calculation unit comprises a planar distance calculation unit calculating a planar distance between each of the plurality of faces when the specific mode is set as a couple mode.
2. The photographing device of claim 1 , wherein the distance comparison unit comprises a planar distance comparison unit comparing the planar distance between each of the plurality of faces with a pre-set reference planar distance and determining propriety of the planar distance calculated by the planar distance calculation unit.
3. The photographing device of claim 1 , further comprising an image input unit delivering the image of the subject to the face recognition unit.
4. The photographing device of claim 1 , further comprising an output unit receiving a result of the comparison from the distance comparison unit, and informing propriety of the calculated distance to a photographer.
5. The photographing device of claim 4 , wherein the output unit informs the propriety of the calculated distance to the photographer by using at least one of a monitor, a speaker, and a light emitting diode.
6. A photographing device photographing a subject, the photographing device configured to be operable in a specific mode and comprising:
a face recognition unit recognizing a face included in an image of the subject;
a distance calculation unit calculating a distance between each of a plurality of faces when the plurality of faces are recognized by the face recognition unit; and
a distance comparison unit comparing the distance calculated by the distance calculation unit with a pre-set reference distance,
wherein the distance calculation unit comprises a front and rear distance calculation unit calculating a front and rear distance between each of the plurality of faces when the specific mode is set as a photo frame mode.
7. The photographing device of claim 6 , wherein the distance comparison unit comprises a front and rear distance comparison unit comparing the front and rear distance between each of the plurality of faces with a pre-set reference front and rear distance and determining propriety of the front and rear distance calculated by the front and rear distance calculation unit.
8. The photographing device of claim 6 , further comprising an image input unit delivering the image of the subject to the face recognition unit.
9. The photographing device of claim 6 , further comprising an output unit receiving a result of the comparison from the distance comparison unit, and informing propriety of the calculated distance to a photographer.
10. The photographing device of claim 9 , wherein the output unit informs the propriety of the calculated distance to the photographer by using at least one of a monitor, a speaker, and a light emitting diode.
11. A method of controlling a photographing device photographing a subject, the method comprising:
(a) entering a specific mode;
(b) photographing a target subject and recognizing a face included in an image of the subject;
(c) calculating a distance between each of a plurality of faces when the plurality of faces are recognized from the image; and
(d) comparing the calculated distance with a pre-set reference distance,
wherein the specific mode is one of a couple mode and a photo frame mode, and
wherein (c) comprises calculating a planar distance between each of the plurality of faces when the specific mode is set as the couple mode.
12. The method of claim 11 , further comprising informing a photographer about a result of the comparing in (d).
13. A method of controlling a photographing device photographing a subject, the method comprising:
(a) entering a specific mode;
(b) photographing a target subject and recognizing a face included in an image of the subject;
(c) calculating a distance between each of a plurality of faces when the plurality of faces are recognized from the image; and
(d) comparing the calculated distance with a pre-set reference distance,
wherein the specific mode is one of a couple mode and a photo frame mode, and
wherein (c) comprises calculating a planar distance between each of the plurality of faces, and a front and rear distance between each of the plurality of faces when the specific mode is set as the photo frame mode.
14. The method of claim 13 , further comprising informing a photographer about a result of the comparing in (d).
