For a better understanding of the invention, and to show how embodiments of the same may be carried into effect, reference will now be made, by way of example, to the accompanying diagrammatic drawings, in which:
Figure 1 is a block diagram showing the structure of is a digital video camera according to the present invention; Figure 2 is a flowchart showing a method for recording data photographed in a snapshot photographing mode according to the present invention; and Figure 3 is a flowchart showing a method for searching image data photographed in a snapshot mode and recorded on a recording medium at a high speed and transferring the same according to the present invention.
The apparatus shown in Figure 1 includes an input unit 10 for applying a predetermined command, a recording/ reproducing unit 12, a sense signal detector 14 for sensing image data photographed in a snapshot mode, a transferring unit 16 for transferring the captured image data to a personal computer (PC) 20, and a controller 18.
The input unit 10 applies a command of photographing in a snapshot mode and of automatically searching and transferring the snapshot photographed image data.
1 - 5 The recording/ reproducing unit 12 includes a camera 120, a signal processor 122, a modulating and demodulating unit 124, an amplifier 126, a recording medium 128 such as magnetic tape, and a sub-code data processor 130. In a recording mode, the recording/reproducing unit 12 records the image data photographed in the snapshot mode and the sense signal for sensing the snapshot photographed image data so as to respectively correspond to a video area and a sub-code area of the recording medium. In a search mode, the recording/reproducing unit 12 searches the recorded image data by the sense signal and captures the searched data.
The sense signal detector 14 detects the snapshot is photographing sense signal stored in the sub-code area of the recording medium 128.
The transferring unit 16 includes a parallel to serial data converter 160, a memory 162, and a level converter 164. The transferring unit 16 stores the image data captured in the recording/reproducing unit 12 and transfers the image data in units of one frame according to a predetermined control signal.
The controller 18 receives a predetermined command from the input unit 10, controls the sense signal detector 14 to operate, receives the snapshot photographing sense signal from the sense signal detector 14, controls the recording/reproducing unit 12 so as to capture the image data corresponding to the received sense signal, and controls the transferring unit 16 to transfer the captured image data to the PC 20.
The apparatus shown in Figure 1 operates as follows.
First, when a snapshot photographing command is applied through the input unit 10, the controller 18 controls the signal processor 122 so that the photographed image data. from the camera 120 and the sense signal corresponding to the image data are respectively recorded on the video area and the sub-code area of the recording medium 128. on the other hand, the sub-code data processor 130 encodes the data of the sub-code area processed in the signal processor 122, namely, the sense signal.
When a command of searching the snapshot photographed image data from the recording medium 128 on which the snapshot photographed data are recorded and of transferring the searched image data is applied through the input unit 10, the controller 18 controls the sense signal detector 14 to resume an operation, receives the sense signal from the sense signal detector 14, controls the signal processor 122 to capture the image data corresponding to the sense signal, and controls the transferring unit 16 to transfer the image data captured in the signal processor 122.
The transferring unit 16 converts parallel data output from the signal processor 122 to serial data, stores the converted data in units of one frame, converts the serial data level to a level corresponding to an RS232C protocol, and transfers the converted data to the PC 20.
In the present invention, a series of operations of searching a plurality of snapshot photographed image data stored in the recording medium according to the sensing signal and transferring the searched image data to PC are continuously and automatically performed.

In step 200, a snapshot photographing command is applied.
In step 202, the image data photographed one frame and the sense signal for sensing the image data are respectively recorded on the video area and the sub-code area of the recording medium.
Figure 3 is a flowchart showing a method for searching the image data photographed in the snapshot mode and recorded on the recording medium at a high speed and for transferring the searched image data.
In step 300, the command of automatically searching snapshot photographed image data and transferring the same is applied.
In step 302, it is determined whether the sense signal of the snapshot photographed image data of the subcode area is detected.
In step 304, when the sense signal is detected, the image data of the video area corresponding to the detected sense signal is captured.
In step 306, the captured image data is transferred. Here, the image data of one frame unit is transferred. Next, when it is determined the transfer of the image data of one frame unit is completed (step 308) and the transfer of the image data of one frame is completed, the steps 302 through 306 are repeated so as to detect and transfer the image data of the next frame.
