In one embodiment, each sync signal may be generated and transmitted in every frame. In this case, each sync signal is assigned specific data in units of frames, and the response data of the response signal includes specific data corresponding to each sync signal, thereby distinguishing that the signal corresponds to the specific sync signal.

However, the present invention is not limited thereto, and the synchronization signal may be generated at regular frame intervals and transmitted to the wireless microphone 20, and the wireless microphone 20 may generate and transmit a response signal corresponding to the synchronization signal.

To this end, the control method S400 of the digital image processing apparatus according to the present invention may be a program or algorithm stored in the storage means of FIG. 2 or implemented in the form of a semiconductor chip such as firmware.

Therefore, in the method S400 of controlling the digital image processing apparatus, the same matters as those described for the digital image processing apparatus and the control apparatuses 200 and 300 will be referred to, and detailed description thereof will be omitted.

In the response signal receiving step S440, a response signal corresponding to the synchronization signal is received. In the synchronization encoding steps S450 and S460, the video data is encoded by synchronizing the video data with the audio data in consideration of the time difference between the sync signal and the response signal.

When the response signal corresponding to the synchronization signal is received in the response signal receiving step S440, the synchronization encoding steps S450 and S460 may be performed. In this case, when the response signal corresponding to the synchronization signal is not received, the voice data input step S430 may be performed until the response signal is received.

The wireless microphone may receive the synchronization signal transmitted in the synchronization signal transmission step S420, and transmit the response signal corresponding to the synchronization signal to be received in the response signal reception step S440.

The synchronization encoding steps S450 and S460 may include a delay time calculating step S450 and an encoding step S460. In the delay time calculating step (S450), a delay time is calculated from the difference between the transmission time of transmitting the synchronization signal and the reception time of receiving the response signal.

In the encoding step S460, the video data is encoded by synchronizing the video data with the audio data in consideration of the delay time. In this case, the audio data may be delayed by the delay time to synchronize with the video data.

The video signal and the audio signal may be input together when the video is captured. Meanwhile, the voice signal may be input through a microphone provided in the main body as shown in FIG. 1, in which case the operation sound of the camera may be input together.

However, according to an exemplary embodiment of the present invention, the voice signal may be input through a wireless microphone installed far away from the main body and installed near the subject. Therefore, since it can be far from the main body of the digital image processing apparatus, it is possible to reduce or hardly record the operation sound.

On the other hand, when the wireless microphone is far away, the audio signal may be input later than the video signal at the time of video recording according to the wireless reception rate. Accordingly, the audio data may be encoded slowly compared to the video data at the time of encoding the video data.

Therefore, by synchronizing the video data of the video signal with the data of the audio signal in consideration of the time difference between the synchronization signal and the response signal, the video signal and the audio signal can be synchronized during video shooting.

To this end, a delay time may be obtained from a difference between a transmission time of transmitting the synchronization signal and a reception time of receiving the response signal, and the audio data may be delayed by the delay time to synchronize with the video data.

On the other hand, the video may be provided with frame data sequentially input at a set time interval. The frame data may include the image data and the audio data.

The voice data may include response data corresponding to the response signal. At this time, the response signal receiving step (S440) may extract the response signal from the response data.

In this case, the response signal may include the same data as the synchronization signal. Therefore, it can be identified that the response signal corresponding to the transmitted specific synchronization signal. The synchronization signal may be transmitted at set time intervals.

In one embodiment, each sync signal may be generated and transmitted in every frame. In this case, each sync signal is assigned specific data in units of frames, and the response data of the response signal includes specific data corresponding to each sync signal, thereby distinguishing that the signal corresponds to the specific sync signal.

However, the present invention is not limited thereto, and the synchronization signal may be generated at a predetermined frame interval and transmitted to the wireless microphone, and the response signal corresponding to the synchronization signal may be generated and transmitted again from the wireless microphone.

In this case, the wireless data communication used is Bluetooth, Wireless Broadband Internet (HSDPA), high speed downlink packet access (HSDPA), wideband code division multiple access (WCDMA), Near Field Communication (NFC), Wi-Fi (Wi- Any one of Fi, WiMax, ZIGBEE, ultra wideband (UWB), Infrared Data Association (IRDA), and other short-range wireless communication technology positioning techniques may be used.
