Method and apparatus for correcting hand-shake in digital image processing apparatus

1. A digital image processing apparatus comprising:

a shutter button operating in two stages, the two stages comprising a half-shutter state and a full-shutter state;

a first filter filtering shock-waves generated in the half-shutter state when a half-shutter signal is in an ON state; and

a second filter filtering shock-waves generated in the full-shutter state when a full-shutter signal is changed from an ON state to an OFF state.

2. The digital image processing apparatus of claim 1 , wherein the first filter and the second filter operate from when the shutter button is pushed until a photographing operation is finished.

3. The digital image processing apparatus of claim 1 , wherein the half-shutter state focuses and exposes an image.

4. The digital image processing apparatus of claim 1 , wherein the full-shutter state occurs when the shutter button is completely pushed.

5. The digital image processing apparatus of claim 1 , wherein the first filter is a high pass filter.

6. The digital image processing apparatus of claim 5 , wherein the second filter is a high pass filter.

7. The digital image processing apparatus of claim 1 , wherein the first filter is a low pass filter.

8. The digital image processing apparatus of claim 7 , wherein the second filter is a low pass filter.

9. The digital image processing apparatus of claim 1 , wherein shock waves generated in the half-shutter state are of a different frequency than shock waves generated in a full-shutter state.

10. A digital image processing apparatus comprising:

an optical hand-shake corrector based on a lens compensation or an image sensor compensation for correcting a hand-shake when the hand-shake is not generated due to operation of a shutter button; and

a shutter-button hand-shake processor using one or more filters for correcting a hand-shake when the hand-shake is generated due to operation of the shutter button.

11. The digital image processing apparatus of claim 10 , wherein the shutter button is operated in two stages that comprise a half-shutter state and a full-shutter state, and the hand-shake processor comprises the following: a first filter filtering shock-waves generated in the half-shutter state when a half-shutter signal is in an ON state; and a second filter filtering shock-waves generated in the full-shutter state when a full-shutter signal is changed from an ON state to an OFF state.

12. The digital image processing apparatus of claim 11 , wherein shock waves generated in the half-shutter state are of a different frequency than shock waves generated in a full-shutter state.

13. A method of correcting hand-shake in a digital image processing apparatus, in which includes a shutter button operating in two stages that comprises a half-shutter state and a full-shutter state, the method comprising:

filtering shock-waves generated in the half-shutter state when a half-shutter signal is in an ON state; and

filtering shock-waves generated in the full-shutter state when a full-shutter signal is changed from an ON state to an OFF state.

14. The method of claim 13 , further comprising taking a photograph of an image.

15. The method of claim 13 , wherein the half-shutter state focuses and exposes an image.

16. The method of claim 13 , wherein the full-shutter state occurs when the shutter button is completely pushed.

17. A method of correcting hand-shake in a digital image processing apparatus, the method comprising:

correcting a hand-shake optically based on a lens compensation or an image sensor compensation when the hand-shake is not generated due to operation of a shutter button; and

correcting a hand-shake by using one or more filters when the hand-shake is generated due to operation of the shutter button.

18. The method of claim 17 , wherein the shutter button is operated in two stages that comprises a half-shutter state and a full-shutter state, and the correcting of a hand-shake using the filters comprises: filtering shock-waves generated in the half-shutter state when a half-shutter signal is in an ON state; and

filtering shock-waves generated in the full-shutter state when a full-shutter signal is changed from an ON state to an OFF state.

19. The method of claim 18 , wherein the first filter is a high pass filter.

20. The method of claim 19 , wherein the second filter is a high pass filter.
