  image data of the following image ("frame").

  The above objects and advantages of the present invention will become more apparent from a detailed description of a preferred embodiment thereof with reference to the accompanying drawings, in which: Figure 1 is a block diagram showing the structure of a digital video camera according to the present invention; Fig. 2 is a flowchart showing a method for recording photographed data in instant photography mode according to the present invention; and Fig. 3 is a flowchart showing a method for searching image data photographed in instant mode and recorded on a high speed recording medium and for transferring

  these according to the present invention.

  The device shown in Figure 1 includes an input unit 10 for applying a predetermined command, a recording / reproducing unit 12, a detection signal detector 14 for detecting image data photographed in instant mode, a unit 16 to transfer the captured image data to a computer

  staff (PC) and a controller 18.

  The input unit 10 applies a command for photography in instant mode and for automatic search and transfer of image data.

photographed instantly.

  The recording / reproducing unit 12 includes a camera 120, a signal processor 122, a modulation and demodulation unit 124, an amplifier 126, a recording medium 128 and a subcode data processor 130. In recording mode, the recording / reproducing unit records the photographed image data in instant mode and the detection signal to detect the photographed instant image data so as to correspond to a video area and to a subcode area of the recording medium. In search mode, the recording / reproducing unit 12 searches for the image data recorded by the detection signal and captures the

data sought.

  Detection signal detector 14 detects the snapshot detection signal stored in the media subcode area

128.

  The transfer unit 16 includes a parallel / serial data converter 160, a memory 162 and a

  164 level converter (RS-232C level converter).

  The transfer unit 16 stores the image data captured in the recording / reproducing unit 12 and transfers the image data in units of an image ("frame") according to a predetermined control signal . The controller 18 receives a predetermined command from the input unit 10, controls the detection signal detector 14 to operate it, receives the detection signal for instant photography from the detection signal detector 14, controls the recording / reproducing unit 12 for capturing the image data corresponding to the received detection signal, and controls the transfer unit 16 for

  transfer the captured image data to the PC 20.

  The device shown in Figure 1 operates from

the following way.

  First, when an instant photography command is applied through the input unit 10, the controller 18 controls the signal processor 122 so that the image data photographed from the camera 120 and the detection 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 subcode data processor 130 codes the data of the subcode area processed in the signal processor 122, namely, the detection signal. When a command to search for the instant photographed image data from the recording medium 128 on which the instant photographed data is recorded and to transfer the searched image data, is applied through the unit d input 10, the controller 18 controls the detection signal detector 14 to resume an operation, receives the detection signal from the detection signal detector 14, controls the signal processor 122 to capture the image data corresponding to the detection signal, and controls the transfer unit 16 to transfer the data

  of images captured in the signal processor 122.

  The transfer unit 16 converts parallel data delivered by the signal processor 122 into serial data, stores the data converted into units of an image ("frame"), converts the level of the serial data to a corresponding level to an RS-232C protocol and transfers the converted data

at PC 20.

  In the present invention, a series of operations consisting in searching for a plurality of instant photographed image data stored in the recording medium according to the detection signal and in transferring the searched image data to the PC are accomplished by continuously and automatically. Fig. 2 is a flowchart showing a method for recording the photographed data in the recording mode

  instant photography according to the present invention.

  In step 200, a photograph command

instant is applied.

  In step 202, the photographed image data of an image ("frame") and the detection signal for detecting the image data are respectively

  recorded in the video area and in the sub-area

record carrier code.

  Fig. 3 is a flowchart showing a method for searching the image data photographed in instant mode and recorded on the high speed recording medium and for transferring the searched image data, according to the present invention. In step 300, the command to automatically search for photographed image data

  instant and transfer these is applied.

  In step 302, it is determined whether the detection signal of the snapshot image data of the subcode area is detected or

no.

  In step 304, when the detection signal is detected, the image data of the video area corresponding to the detected detection signal are captured. In step 306, the captured image data is transferred. At this stage, the image data of an image unit ("frame") is transferred. Then, when it is determined that the transfer of image data from an image unit ("frame") is complete (step 308) and that the transfer of image data from an image ("frame") ) is completed, steps 302 to 306 are repeated so as to detect and transfer

  the image data of the following frame.

  According to the present invention, quick search and continuous transfer can be accomplished by recording the snapshot detection signal corresponding to the snapshot mode of snapshot data data on the subcode area.

  and using it during their reproduction.
