Disclosed is an apparatus and method for color interpolation in a digital photographing device, the apparatus comprising an optical unit including a lens and a lens adjuster so as to receive an optical signal, an image sensor installed to be movable in a predetermined direction, wherein the image sensor converts the optical signal input through the optical unit into a digital signal, in order to obtain raw data based on a unit of a frame, the raw data including color information about one color of each pixel according to a color filter array (CFA) of a predetermined format, a buffer for storing the raw data obtained by the image sensor, a sensor movement controller for controlling a movement state and a movement distance of the image sensor so as to obtain at least two frames of raw data, one of which has an offset from one image through the image sensor, when said one image is photographed, a sensor movement driving unit for moving the image sensor under a control of the sensor movement controller and an image processing unit for converting said at least two frames of raw data stored in the buffer into image data, which have a plurality of pieces of color information predetermined to enable expression of an original color for each pixel, by using color interpolation.
