Security mode start time, time interval, etc.) to provide a control signal for generating a setting menu screen (OSD screen) to the menu generation block 104, and to display the security mode information setting menu screen through a monitor (not shown). The signal is provided to a signal processing block 106.

In addition, the control block 102 registers and registers the security mode information to provide a control signal for capturing an image to the camera 108 when the preset start time is reached in the state of performing the security mode, and the menu generation block 104. A control signal for transferring the generated image information (eg, image capture date, image capture time, etc.) OSD to the decoding block 108, and mixing and decoding the captured image together with the image information OSD thereof. Is provided to the decoding block 110, and a control signal for compressing the decoded mixed image in the JPEG method or the like is provided to the video codec block 112.

In addition, in the control block 102, a file name (e.g., 2004/11/30/14 /) that displays image information (e.g., image capture date, image capture time, etc.) of the image captured by the camera 108. 30, etc.) to the DVD loader block 114 to provide a control signal to the DVD loader block 114 for storing (recording) the compressed video in the JPEG method or the like as a still image on the mounted DVD. Performs the function of.

Next, the menu generation block 104 generates a security mode setting menu screen (OSD screen) according to the control signal provided from the control block 102 and transmits it to the signal processing block 106, and the signal processing block 106. In FIG. 2, the monitor displays the image through a monitor (not shown) and generates an image information OSD of an image captured by the camera 108 in the security mode and transmits the image information OSD to the control block 102.

On the other hand, the camera 108 is configured in the recording system, and captures the image according to the control signal provided from the control block 102 and transmits to the decoding block 110.

In addition, the decoding block 110 mix-decodes the image captured by the camera 108 with the image information OSD thereof according to the control signal provided from the control block 102, and decodes the decoded image. To pass.

Next, the video codec block 112 compresses the decoded image to be transmitted in a JPEG manner or the like, and transmits the decoded image to the DVD loader block 114 for storage, and in the DVD loader block 114 from the control block 102. The video information and the still picture are stored (recorded) on the mounted DVD according to the file name indicating the provided video information.

Meanwhile, the present invention described above has been described in which the image captured by the camera and the image information thereof are compressed in the JPEG method and stored in the DVD as the image information and the still image. Of course, it can be displayed through a monitor not shown.

Next, in the recording system having the above-described configuration, when the preset start time is reached when the security mode is performed, the captured image is mixed with the image information therefor, and the mixed image is compressed on the DVD by compressing the JPEG method. A process of storing the captured image as the second image information and the still image at a predetermined time interval after storing the image information and the still image will be described.                     

2 is a flowchart illustrating a process of recording an image captured by a camera as image information and a still image in the recording system according to the present invention.

Referring to FIG. 2, in a standby mode of a recording system for recording an image using a DVD (step 202), in a control block 102, a user uses a security means using an input unit (not shown), for example, a remote controller or the like. It is checked whether to enter a key for performing (step 204).

As a result of the check in step 204, when a key for executing the security mode is input, the control block 102 generates a control signal for generating a menu screen (OSD screen) for setting security mode information. In response thereto, the menu generation block 104 generates a menu screen for setting the security mode information, and displays the security mode information according to the monitor not shown through the signal processing block 106. When setting registration is registered, the control block 102 records (stores) it in a storage medium (for example, a memory or the like) not shown (step 206).

In the security mode of the recording system (step 208), the control block 102 checks whether the current time is the preset time T according to the preset security mode information (step 210). Here, the preset time T means a security mode start time (for example, November 30, 2004 14:30, etc.) of the preset security mode information.

As a result of the check in the step 210, when the current time is a preset time T, the menu generation block 104 according to the control signal provided from the control block 102, the image information of the captured image (for example, , An image capturing date, an image capturing time, etc.) and generates an OSD to the control block 102 (step 212).

Then, the image is captured by the camera 108 according to the control signal from the control block 102, and the captured image is mixed with the image information (for example, image capture date, image capture time, etc.) OSD and decoded. After that, the image is compressed (JPEG) or the like to store (record) the first image information and the still image on the DVD according to the file name of the corresponding image information (step 214).

Next, the control block 102 checks whether the time elapsed after storing the first image information and the still image on the DVD becomes a preset time t (step 216). Here, the preset time t means a time interval (for example, 5 seconds, 10 seconds, etc.) of the preset security mode information.

As a result of the check in the step 216, when the elapsed time becomes the preset time t, the menu generation block 104 according to the control signal provided from the control block 102, the image information of the captured image at this time An OSD is generated and provided to the control block 102 (eg, image capture date, image capture time, etc.) (step 218).

Then, the image is captured by the camera 108 according to the control signal from the control block 102, and the captured image is mixed with the image information (for example, image capture date, image capture time, etc.) OSD and decoded. After that, the second image information and the still image are stored (recorded) on the DVD according to the file name of the corresponding image information by compressing it in the JPEG method or the like (step 220).

In addition, the control block 102 checks whether there is a key input to end the security mode after storing the second image information and the still image on the DVD (step 222), and if there is no key input to end the security mode, the control block 102 In operation 102, the elapsed time is continuously checked to determine whether the elapsed time becomes a predetermined time t, and accordingly, the process of continuously storing (recording) the image information and the still image of the image captured by the camera 108 on a DVD ( That is, the security mode is continuously performed), and if there is a key input to terminate the security mode, the control block 102 releases the security mode (step 224).

Therefore, when the security mode start time is reached according to the preset security mode information in a recording system for recording an image using a DVD, the preset time after storing (recording) the first image information and the still image of the captured image on the DVD. When the interval is reached, the second image information and the still image of the captured image may be recorded on the DVD, and the security mode may be continuously performed at a predetermined time interval.

As described above, the present invention is different from the conventional method of continuously recording an image captured by a recording system configured with a separate camera to a DVD, and a security mode key of the recording system in a recording system for recording an image using a DVD. If there is an input, after setting and registering the security mode information, when the preset start time is reached according to the security mode information, the image captured by the camera and the image information thereof are recorded on the DVD, thereby recording a still image having a small capacity. A security system that can record in a long time security mode can be implemented.
