According to an embodiment of the present invention, a digital photographing apparatus comprises: an image obtaining signal receiver, an external interface, a controller, a first timing generator, a filter motor, a second timing generator, a photographing element, an image processor and a memory. The image obtaining signal receiver receives an image obtaining signal. The external interface receives a passing band setting input. The controller sets a passing band using a start wavelength, an end wavelength and a predetermined bandwidth extracted from the passing band setting input. The first timing generator generators at least one of a pulse signal corresponding to the passing band, a driving voltage value and a driving current value. The filter motor overlaps a low band passing filter with a high band passing filter to correspond to the passing band in accordance with at least one of the pulse signal, the driving voltage value and the driving current value. The photographing element receives light penetrated through the low band passing filter and the high band passing filter to output an analog voltage while corresponding to a clock. The image processor processes an image with the analog voltage. The memory stores the processed image. |
