PHOTOGRAPHING METHOD AND APPARATUS
Provided are a photographing method and apparatus for implementing the method. The photographing method includes setting coordinates where a face to be photographed is to be positioned and setting a size of the face, detecting a face from a preview image of a predetermined subject according to the coordinates and the size, and photographing the subject when a face corresponding to the coordinates and the size is detected from the preview image. Thus, coordinates where a face is positioned and a facial size can be adjusted when a user wants to perform a self-photographing operation.
1 . A photographing method comprising:
setting coordinates where a face to be photographed is to be positioned and setting a size of the face;
detecting a face from a preview image of a predetermined subject according to the set coordinates and size; and
photographing the subject when a face corresponding to the set coordinates and size is detected from the preview image.
2 . The photographing method of claim 1 , wherein the photographing further comprises:
determining whether the detected face is a smiling face, and wherein the subject is photographed when the detected face is a smiling face.
3 . The photographing method of claim 1 , wherein the detecting further comprises notifying a user of non-detection information when the face corresponding to the set coordinates and size is not detected from the preview image.
4 . The photographing method of claim 3 , wherein the non-detection information comprises information for guiding a difference in at least one of coordinates and facial size between the set face and the face detected by the preview image.
5 . The photographing method of claim 3 , wherein the notification is performed using one of a beep tone, a voice and a directional indication of a light emitting diode (LED).
6 . The photographing method of claim 2 , further comprising notifying a user of expression determining information when the detected face is not a smiling face.
7 . The photographing method of claim 2 , further comprising notifying a user that preparation for photographing is completed when the face corresponding to the set coordinates and size is detected from the preview image.
8 . The photographing method of claim 1 , further comprising, prior to the setting:
selecting a self-photographing mode, wherein the selecting is performed by a user.
9 . The photographing method of claim 1 , wherein the set coordinates and size are set by a user's input.
10 . A photographing method comprising:
setting coordinates where a face to be photographed is to be positioned and a size of the face, wherein the setting is performed by a user's input;
detecting a face from a preview image of a predetermined subject according to the set coordinates and size;
determining whether an expression of the face is a smiling expression when a face corresponding to the coordinates and the size is detected from the preview image; and
photographing the subject when the face is determined to be a smiling face.
11 . The photographing method of claim 10 , wherein the detecting further comprises notifying a user of non-detection information when the face corresponding to the set coordinates and size is not detected from the preview image.
12 . The photographing method of claim 10 , further comprising notifying a user of expression determining information when the detected face is not a smiling face.
13 . A computer readable recording medium having recorded thereon computer readable program code comprising a program for executing a photographing method, comprising:
setting coordinates where a face to be photographed is to be positioned and setting a size of the face;
detecting a face from a preview image of a predetermined subject according to the set coordinates and size; and
photographing the subject when a face corresponding to the set coordinates and size is detected from the preview image.
14 . A photographing apparatus comprising:
a coordinate setting unit for setting coordinates where a face to be photographed is to be positioned;
a size setting unit for setting a size of the face;
a detector for detecting a face from a preview image of a predetermined subject according to the set coordinates and size; and
a controller for controlling photographing of the subject when the face detector detects a face corresponding to the set coordinates and size from the preview image.
15 . The photographing apparatus of claim 14 , further comprising an expression determining unit for determining whether the detected face is a smiling face,
wherein the controller controls photographing of the subject when expression determining unit determines that the detected face is a smiling face.
16 . The photographing apparatus of claim 15 , further comprising a notification controller for notifying a user about non-detection information when the face detector does not detect the face corresponding to the set coordinates and size from the preview image.
17 . The photographing apparatus of claim 16 , wherein the non-detection information comprises information for guiding a difference in at least one of the coordinates and facial size between the set face and the face detected by the preview image.
18 . The photographing apparatus of claim 16 , wherein the notification controller notifies a user that preparation for photographing is completed when the face corresponding to the set coordinates and size is detected from the preview image.
19 . The photographing apparatus of claim 16 , wherein the notification controller notifies the user of expression-determining information when the expression of the face is not a smile expression.
20 . The photographing apparatus of claim 16 , wherein the coordinates and the size are set by a user's input.
