  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Needless to say, the present invention is not limited to the following examples, and can be arbitrarily changed without departing from the gist of the present invention.

  The present invention is applied to, for example, a camera-integrated recording / reproducing apparatus 100 configured as shown in FIG.

  This camera-integrated recording / reproducing apparatus 100 is a so-called camcorder configured by combining a video camera and a recording medium such as a hard disk drive or a semiconductor memory so that it can be carried and used. An image pickup unit 10 including an image pickup device 12 for picking up an image, an image data processing circuit 13 for generating digitized image data from an image pickup signal obtained by the image pickup device 12, an operation panel 20, a device ID storage circuit 30, a group code storage A circuit 40, an authentication circuit 50, and the like are provided in the apparatus main body 1, and a recording media unit 60 including a recording medium 61 in which image data obtained by the imaging unit 10 is recorded is detachable from the apparatus main body 1. It is installed.

  The recording media unit 60 includes a recording medium 61, an authentication ID storage circuit 62, a timer 63, a battery 64, a security guard circuit 65, and the like.

  The authentication circuit 50 communicates with the authentication ID storage circuit 62 in the recording media unit 60, assigns the authentication ID, and releases the security guard by confirming the device ID and the like. Communication with the recording medium 61 is established.

  In this camera-integrated recording / reproducing apparatus 100, even if the recording media unit 60 is once taken out from the apparatus main body 1, if the recording media unit 60 is mounted again within a predetermined time, the authentication is performed again without changing from the state in which the recording media unit 60 is continued. In order to realize a device in which recording / playback is possible without a confirmation procedure, and when the removed time exceeds a certain time, an authentication confirmation procedure is required for recording / playback again. A timer 63 is provided, which has a function of counting the time removed from the apparatus main body 1 and setting a security guard for the recording medium 61 when a predetermined time has passed.

  When the count value of the timer 63 in the recording media unit 60 is less than a certain value (for example, 5 minutes) in the recording media unit 60 that is reattached to the camera-integrated recording / reproducing apparatus 100 to which the authentication ID is assigned, a new authentication check is performed. Recording, playback, and erasing of the recording medium 61 can be performed without the above procedure. When the count time of the timer 63 exceeds a certain time (for example, exceeds 5 minutes), the security guard of the recording medium 61 is set by the security guard circuit 65, and a procedure for manual authentication confirmation by the camcorder operator is performed. Thus, communication with the recording medium 61 can be established, and recording / playback / erasing can be performed.

  The timer 63 of the recording media unit 60 is operated by a battery 64, and the battery 64 is charged by a charging circuit (not shown) when it is attached to the camera-integrated recording / reproducing apparatus 100. In the unlikely event that the battery 64 is discharged and sufficient power is not supplied, it is assumed that the set time has elapsed, and when the power is restored after being mounted again, the security guard by the security guard circuit 65 is set. To do.

  In this camera-integrated recording / reproducing apparatus 100, the group code storage circuit 40 stores the group code registered by the operation panel 20 or the like, and the recording media units 60 attached to the apparatus main body 1 belong to the same group. If an authentication ID is given by another device and the count value of the timer 63 in the recording media unit 60 is below a certain value (for example, 5 minutes), additional recording / recording on the recording media 61 is performed without a new authentication confirmation procedure. Can play. When the count time of the timer 63 exceeds a certain time (for example, exceeds 5 minutes), a security guard is set by the security guard circuit 65 of the recording medium 61, and a manual authentication confirmation procedure is performed by the camcorder operator. As a result, additional recording / reproduction with respect to the recording medium 61 can be performed.

  The security guard circuit 65 sets / cancels the security guard of the recording medium 61 according to the procedure shown in the flowchart of FIG.

  That is, the security guard circuit 65 of the recording media unit 60 determines whether or not the recording media unit 60 is in the mounted state (step S1), and the determination result is YES, that is, the recording media unit 60 is a camera-integrated recording / reproducing device. If it is attached to the apparatus main body 1 of the apparatus 100, it is determined whether or not it has been authenticated by the authentication circuit 50 of the camera-integrated recording / reproducing apparatus 100 (step S2). If the determination result in step S2 is NO, that is, if the authentication process is not completed, the process returns to step S1 and steps S1 and S2 are repeated until the authentication process is completed. When the determination result in step S2 is YES, that is, when the authentication process is completed, the security guard by the security guard circuit 65 is canceled and the timer 63 is reset (step S3), and the process returns to step S1.

  Thus, when the recording media unit 60 is attached to the apparatus main body 1, the security guard circuit 65 repeatedly performs the processes in steps S1 to S3, and the determination result in step S1 is NO. That is, when the recording media unit 60 is removed from the apparatus main body 1, the timer 63 starts counting (step S4), and it is determined whether or not the count time of the timer 63 exceeds a predetermined time (step S5).

  If the determination result in step S5 is NO, that is, if the count time of the timer 63 does not exceed the predetermined time, the security guard circuit 65 returns to step S4 and repeats step S4, and the determination result in step S5. Is YES, that is, when the count time of the timer 63 exceeds a predetermined time, a security guard is set and the process is terminated.

  Here, when recording on the recording medium 61 in the initialized state, the security guard is applied by the security guard circuit 65, but since the authentication ID is not set, a manual authentication procedure is performed from the operation panel 20, The authentication circuit 50 issues a basic authentication ID based on this authentication and writes this basic authentication ID in the authentication ID storage circuit 30.

  The authentication circuit 50 receives the device ID from the device ID storage circuit 30, creates a device authentication ID by a predetermined method, and stores it in the authentication ID storage circuit 62 of the recording media unit 60 mounted in the device main body 1. The created device authentication ID can be written.

  Further, the authentication circuit 50 receives the group code from the group code storage circuit 40, creates a group authentication ID by a predetermined method, and stores the group authentication ID in the authentication ID storage circuit 62 of the recording media unit 60 attached to the apparatus body 1. An authentication ID can be written.

  At this time, it is assumed that the authentication circuit 50 uses various methods such as a hash function that cannot easily estimate the original information when creating each authentication ID.

  In order to access the recording medium 61 to which the security guard is applied by the security guard circuit 65, manual authentication is performed from the operation panel 20 in the same procedure as when the recording medium 61 is initialized, and the authentication circuit 50 has an authentication ID storage circuit. If the basic authentication ID exists in 62, it is checked against this and the security guard circuit 65 is notified whether authentication is possible or not.

  As the manual authentication method, any authentication method such as a password input method using a keyboard, a fingerprint authentication method, and an ID card authentication can be used. Depends on the implementation of each device.

  In the camera-integrated recording / reproducing apparatus 100 having such a configuration, as shown in FIG. 3, even if the recording media unit 60 is detached from the apparatus main body 1, it is re-authenticated when it is mounted again for a short time. Because there is no, you can work quickly.

  In addition, as shown in FIG. 4, even if the recording media unit 60 is moved to another camera-integrated recording / reproducing apparatus 200 in the same group during shooting, if the removed time is short, authentication is performed again. Therefore, it is possible to continue shooting with additional recording speedily.

  Also, even if the recorded recording media unit 60 is moved to the field editing machine of the same group, if it is removed for a short time, the authentication is not performed again, so that it can be played back quickly and the editing operation can be performed. Can do.

  Further, when the recording media unit 60 is removed from the camera-integrated recording / reproducing apparatus 100 main unit 1 and a certain time has elapsed, even if the same apparatus is used, manual re-authentication is required for recording / reproducing / erasing. It is possible to call attention to accidents that are recorded over recorded media.

  Furthermore, when the recording media unit 60 is removed from the apparatus main body 1 of the camera-integrated recording / reproducing apparatus 100 and a predetermined time has passed, it is necessary to authenticate again even during reproduction, so that the recorded information is reproduced without permission. Can be prevented.

  Note that even when this type of recording media unit 60 recorded by a certain camera-integrated recording / reproducing apparatus is mounted on an editing machine belonging to the same group, only additional recording / reproduction can be performed as in the case of a camera-integrated recording / reproducing apparatus.

  The recording media unit 60 may be a non-contact recording medium that wirelessly communicates with the camera-integrated recording / reproducing apparatus 100. In this case, the case where the recording media unit 60 is out of the communicable range is regarded as being removed from the camera-integrated recording / reproducing apparatus 100. The battery 64 may be charged by non-contact power transmission.

  The authentication confirmation procedure by the operator of the camera-integrated recording / reproducing apparatus 100 is not limited to the operation using the operation panel 20, but may be another manual method such as insertion of an ID card. The authentication circuit 50 may issue other authentication IDs. For example, an authentication ID that allows all operations such as recording, playback, and erasing to be performed by devices other than the recorded device may be generated and written to the authentication ID storage circuit 62.
