PURPOSE: A photographing device for automatically setting a compression type and a method therefor are provided to automatically set the compression type of image data according to a kind of a camera and a recording medium selected by a user. CONSTITUTION: A DVC(Digital Video Camera) unit(202) picks up a moving picture through a camera lens. A DVC signal processing block(112) converts an output signal of the DVC unit into digital moving picture data. The first resolution converting unit(171) converts the digital moving picture data into the first resolution. The second resolution converting unit(172) converts the digital moving picture data into the second resolution. An MPEG(Moving Picture Experts Group) compressing unit(182) compresses data outputted from the first resolution converting unit as data with the first format. A DV compressing unit(183) compresses data outputted from the second resolution converting unit as data with the second format. A removable IC memory card(121) stores the data with the first format. A magnetic tape(122) stores the data with the second format. A recording medium selection switch(131) outputs a recording mode signal for selecting one of the removable IC memory card and the magnetic tape. A main control unit(141) transmits the digital moving picture data to one of the MPEG compressing unit and the DV compressing unit on the basis of the recording mode signal. A microphone(132) converts a voice signal into an electric signal. A G.726 compressing unit(184) compresses a signal received from the microphone as data with third format, and stores the data with third format in the removable IC memory card. A PCM(Pulse Code Modulation) compressing unit(185) compresses the signal received from the microphone as data with the fourth format, and stores the data with the fourth format in the magnetic tape.
