In various embodiments, a digital camera may coordinate focusing with compensation of camera shake. The digital camera may include a shutter-signal generating unit which outputs a first shutter signal corresponding to a start of a focusing operation and a second shutter signal corresponding to a start of a photographing operation. The digital camera may also include a digital signal processor which performs a centering operation of a compensation lens in response to the first shutter signal, and which performs a compensation operation of the compensation lens for compensating for a camera shake in response to the second shutter signal.
