Method and apparatus for providing composition information in digital image processing device
View Patent ↗Provided is a method and apparatus for providing composition information in a digital image processing device whereby composition information of a target object displayed in a live-view screen is provided using auditory information or visual information during photographing in order to induce a composition of the target object to be matched to a predetermined composition for photographing. The apparatus includes a detection unit detecting a composition of an object from a live-view image to be captured, a comparison unit comparing the detected composition with a reference composition, and a control unit performing a control operation to output an auditory alert signal until the detected composition is matched to the reference composition and performing a control operation to output an auditory match signal when the detected composition is matched to the reference composition.
1. An apparatus for providing composition information in a digital image processing device, the apparatus comprising:
a detection unit that detects the composition of an object from a live-view image;
a comparison unit that compares the detected composition with a reference composition; and
a control unit that performs a control operation to output an alert signal until the detected composition is matched to the reference composition and that performs a control operation to output a match signal when the detected composition is matched to the reference composition;
wherein the composition of the object can be set by a user, and if the composition of the object is not set by the user, the composition of the object is set to a central portion of a screen.
2. The apparatus of claim 1 wherein the alert signal and the match signal are auditory signals.
3. The apparatus of claim 1 wherein the alert signal and the match signal are visual signals.
4. The apparatus of claim 1 , wherein the composition of the object includes the size, position, and direction of the object and the reference composition includes a size, position, and direction of a reference object.
5. The apparatus of claim 4 , wherein the reference composition can be set by a user.
6. The apparatus of claim 1 , wherein the control unit performs a control operation to output different alert signals until the composition of the object is matched to the reference composition.
7. The apparatus of claim 1 , wherein the control unit performs a control operation to automatically photograph the object when the detected composition is matched to the reference composition.
8. The apparatus of claim 7 , wherein the control unit operates with a predetermined delay between when the match is detected and when the photograph is taken.
9. The apparatus of claim 1 , wherein the auditory alert signal and the auditory match signal include voice message signals.
10. An apparatus for providing composition information in a digital image processing device, the apparatus comprising:
a detection unit that detects the composition of an object from a live-view image;
a comparison unit that compares the detected composition with a reference composition; and
a control unit that performs a control operation to output a visual alert signal until the detected composition is matched to the reference composition and that performs a control operation to automatically capture the live-view image after the match is detected;
wherein the composition of the object can be set by a user, and if the composition of the object is not set by the user, the composition of the object is set to a central portion of a screen.
11. The apparatus of claim 10 , wherein the control unit delays a predetermined time between when the match is detected and when the live-view image is automatically captured.
12. The apparatus of claim 10 , wherein the composition of the object includes the size, position, and direction of the object and the reference composition includes size, position, and direction of a reference object.
13. The apparatus of claim 10 , wherein the visual alert signal is output from a sub light that provides light to the object.
14. The apparatus of claim 13 , wherein the control unit controls a zoom operation by comparing the size of the object with the size of the reference object, adjusts a flickering speed of the sub light by comparing the position of the object with the position of the reference object, and adjusts a color emitted by the sub light by comparing the direction of the object with the direction of the reference object.
15. A method of providing composition information in a digital image processing device, the method comprising:
(a) detecting the composition of an object from a live-view image to be captured;
(b) comparing the detected composition with a reference composition; and
(c) performing a control operation to output an alert signal until the detected composition is matched to the reference composition and performing a control operation to output a match signal when the detected composition is matched to the reference composition;
wherein the composition of the object can be set by a user, and if the composition of the object is not set by the user, the composition of the object is set to a central portion of a screen.
16. The method of claim 15 , wherein the alert signal and the match signal include auditory signals.
17. The method of claim 15 , wherein the alert signal and the match signals include visual signals.
18. The method of claim 15 , further comprising (d) performing a control operation to automatically photograph the object after a lapse of a predetermined time from a point in time when the auditory match signal is output.
19. The method of claim 15 , wherein (c) comprises performing a control operation to output different auditory alert signals until the composition of the object is matched to the reference composition.
20. The method of claim 15 , wherein in (c), the auditory alert signal and the auditory match signal are voice message signals.
21. A method of providing composition information in a digital image processing device, the method comprising:
(a) detecting the composition of an object, including the size, position, and direction of the object, from a live-view image;
(b) comparing the detected composition with a reference composition including size, distance, and direction of a reference object;
(c) outputting a visual alert signal until the detected composition is matched to the reference composition; and
(d) automatically capturing the live-view image after a lapse of a predetermined time if the detected composition of the object is matched to the reference composition;
wherein the composition of the object can be set by a user, and if the composition of the object is not set by the user, the composition of the object is set to a central portion of a screen.
22. The method of claim 21 , wherein the composition of the object can be set by a user, and if the composition of the object is not set by the user, the composition of the object is set to a central portion of a screen.
23. The method of claim 21 , wherein in (c), the visual alert signal includes output from a sub light that provides light to the object.
24. The method of claim 23 , wherein (c) comprises controlling a zoom operation by comparing the size of the object with the size of the reference object, adjusting a flickering speed of the sub light by comparing the position of the object with the position of the reference object, and adjusting a color emitted by the sub light by comparing the direction of the object with the direction of the reference object.
