Camera

1. A camera, comprising:

a shutter button, pressed to trigger a first and a second operation, wherein the first operation triggers an auto-focus enable signal, the second operation triggers an image exposure control signal, and the first operation is prior to the second operation and, between the start of the first operation and the start of the second operation is a first time interval;

a control unit, operated according to the auto-focus enable signal and the image exposure signal;

a photo sensor array, reset by a reset signal that the control unit generates according to the image exposure signal for performing image exposure;

an anti-shake module, enabled and disabled by an anti-shake enable signal triggered and disabled by the control unit, wherein the anti-shake enable signal is triggered when the auto-focus enable signal has been triggered by a second time interval that is not longer than the first time interval; and

a mechanical shutter, enabled and disabled by a control signal triggered and disabled by the control unit, wherein the mechanical shutter is disabled and closed when the image exposure control signal has been triggered by a third time interval,

wherein the control unit disables the anti-shake enable signal and the control signal concurrently.

2. The camera as claimed in claim 1 , further comprising a control unit which is operable to trigger the anti-shake enable signal according to triggering of the image exposure control signal.

3. The camera as claimed in claim 2 , wherein the second time interval equals to the first time interval.

4. The camera as claimed in claim 2 , wherein the control unit further triggers a reset signal according to the image exposure control signal.

5. The camera as claimed in claim 4 , wherein the photo sensor array comprises a plurality of photo sensors which are reset by the reset signal.

6. The camera as claimed in claim 2 , wherein the anti-shake enable signal is disabled according to disabling and closing of the mechanical shutter.

7. The camera as claimed in claim 6 , wherein anti-shake enable signal is disabled after being enabled for the third time interval.

8. The camera as claimed in claim 3 , wherein the anti-shake enable signal is disabled according to disabling and closing of the mechanical shutter.

9. The camera as claimed in claim 8 , wherein anti-shake enable signal is disabled after being enabled for the third time interval.

10. The camera as claimed in claim 1 , wherein the anti-shake enable signal is disabled according to disabling of the image exposure control signal.

11. The camera as claimed in claim 2 , wherein the anti-shake enable signal is disabled according to disabling of the image exposure control signal.

12. The camera as claimed in claim 3 , wherein the anti-shake enable signal is disabled according to disabling of the image exposure control signal.

13. The camera as claimed in claim 1 , wherein the anti-shake enable signal is disabled according to disabling of the auto-focus signal.

14. The camera as claimed in claim 2 , wherein the anti-shake enable signal is disabled according to disabling of the auto-focus signal.

15. The camera as claimed in claim 3 , wherein the anti-shake enable signal is disabled according to disabling of the auto-focus signal.

16. The camera as claimed in claim 1 , wherein the anti-shake enable signal is triggered when the auto-focus enable signal has been triggered and the image exposure control signal is still disabled.

17. The camera as claimed in claim 16 , wherein the anti-shake enable signal is disabled according to disabling of the image exposure control signal.

18. The camera as claimed in claim 16 , wherein the anti-shake enable signal is disabled according to disabling of the auto-focus signal.
