Method of controlling operation of a digital camera to take an identification photograph
View Patent ↗Provided is a method of controlling the operation of a digital camera to order to take an identification photograph in a natural setting by displaying a frame and a reference outline of the identification photograph, performing photographing according to a photographing signal by a user, displaying a detection area to detect an outline of a figure around the reference outline on a photographed image, detecting the outline of the figure in the detection area, and forming a background image for the identification photograph in a set background area with respect to the detected outline.
1. A method of controlling operation of a digital camera to take an identification photograph in a natural setting, the method comprising:
displaying a frame and a reference outline in a display unit;
performing photography;
displaying a detection area adjacent to the reference outline; and
the detection area encompasses the reference outline, such that a portion of the detection area is within an area defined by the reference outline, and another portion of the detection area is outside of the area defined by the reference outline.
2. The method of claim 1 , wherein the method further comprises:
deleting a background area of the photographed image with respect to the detected outline.
3. The method of claim 2 , wherein the method further comprises:
inserting a background image for the identification photograph in the deleted background area.
4. The method of claim 1 , wherein the type of frame and reference outline correspond to specifications input by a user.
5. The method of claim 1 , wherein the step of performing photography includes:
allowing a user to aim the camera and set a zoom factor.
6. The method of claim 5 , wherein the zoom may be an optical or digital zoom.
7. The method of claim 1 , wherein the step of performing photography includes:
taking a digital photograph.
8. The method of claim 1 , wherein the method further comprises:
enlarging or contracting the detection area.
9. The method of claim 8 , wherein the detection area is enlarged or contracted based on user input.
10. A method of controlling operation of a digital camera to take an identification photograph in a natural setting, the method comprising:
allowing a user to input specifications corresponding to type of frame and reference outline for the identification photograph;
displaying the corresponding frame and the corresponding reference outline in a display unit;
allowing the user to aim the camera and set a zoom factor;
taking a digital photograph;
displaying a detection area adjacent to the reference outline;
enlarging, contracting, or maintaining the detection area;
detecting an outline of a figure within the detection area;
deleting a background area of the photographed image with respect to the detected outline; and
the detection area encompasses the reference outline, such that a portion of the detection area is within an area defined by the reference outline, and another portion of the detection area is outside of the area defined by the reference outline.
11. The method of claim 1 , wherein the detecting step comprises:
detecting the outline of the figure based on pixels having a relatively greater gradation difference among pixels in the detection area.
12. The method of claim 10 , wherein the detecting step comprises:
detecting the outline of the figure based on pixels having a relatively greater gradation difference among pixels in the detection area.
