Japanese Patent Laid-Open No. 10-312601
[Problems to be solved by the invention]
As described above, the video camera apparatus uses a video tape as a recording medium, and therefore can only perform sequential recording. Therefore, in order to erase partially unnecessary recorded data (that is, recorded data stored at a predetermined time), a method of operating the rewind button to rewind and overwrite the video tape is used. Thus, there is a first drawback that the trouble of erasing unnecessary recorded data is complicated.
[0005]
In addition, since the erasure operation is performed after all the recorded data has been fetched, there is a second drawback that the recorded data cannot be erased in real time (that is, substantially simultaneously with the recording operation). Therefore, the present invention provides a video camera apparatus that can erase unnecessary recorded data in real time in one touch in consideration of such a conventional drawback.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a video camera device 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 is a front view of the apparatus 1, FIG. 2 is a block diagram of the apparatus 1, FIG. 3 is a flowchart of the apparatus 1, FIG. 4 is a flowchart following FIG. 3, and FIG.
[0011]
As shown in FIG. 1, the casing 2 is made of, for example, metal or plastic and is formed in a substantially box shape. The finder 3 is for a user to look into and is connected to the casing 2. The camera unit 4 captures a subject, and a lens (not shown), a CCD, and the like are provided therein, and is provided in the casing 2 so that it can move linearly.
[0012]
The microphone 5 is connected to the casing 2. The delete button 6, the cancel button 7, the recording button 8, and the playback button 9 are each composed of a key (switch) or the like, and are exposed on the surface of the casing 2.
[0013]
The storage unit 10 is configured to be accessible at random. The storage unit 10 includes, for example, an HDD (Hard Disk Driver), a DVD-RAM, or the like. The storage unit 10 is provided in the casing 2.
[0014]
Next, as shown in FIG. 2, the control unit 11 is composed of, for example, a CPU. The delete button 6, cancel button 7, record button 8, and play button 9 are each connected to the control unit 11 via an input unit (interface circuit) 12.
[0015]
The camera unit 4 is connected to the control unit 11. The subject is converged by the lens of the camera unit 4, and the converged image is converted into bitmap format data by the CCD of the camera unit 4 and input to the control unit 11.
[0016]
The reproduction unit 13 includes a signal processing unit, for example. The recorded data stored in the storage unit 10 is input to the reproduction unit 13 via the control unit 11. The playback unit 13 converts the recorded data into a video signal and outputs the video signal to the output unit 14. The output unit 14 is connected to an input unit of a television (not shown) via a signal line cable (not shown).
[0017]
The ROM 15 is a read-only memory, stores a control program of the control unit 11, and is connected to the control unit 11. The RAM 16 is a random access memory and is connected to the control unit 11.
[0018]
The display unit 17 includes, for example, a liquid crystal display device and is connected to the control unit 11. As described above, the camera unit 4, the storage unit 10, the delete button 6, and the like are connected to the control unit 11. The video camera apparatus 1 is configured by the above components.
[0019]
Next, the operation of the video camera apparatus 1 will be described mainly with reference to FIGS. For example, it is assumed that the user of the video camera apparatus 1 is about to record a scene of my child's race at an athletic meet.
[0020]
First, it is assumed that the user holds the video camera device 1, focuses on the vicinity of the starting point of the race while looking through the finder 3, and presses the recording button 8 in the ON state. The recording button 8 is composed of a toggle switch, for example, and is kept in an on state (energized state) when pressed in an on state. Further, when the recording button 8 is pushed to the off state, the off state (non-energized state) is maintained.
[0021]
At this time, the control unit 11 affirms the determination of “whether or not the recording button 8 is on” (see S1 in FIG. 3). And the control part 11 makes the memory | storage part 10 clear the memory | storage data of a video recording position (refer S2 of FIG. 3).
[0022]
Next, the control unit 11 determines whether or not recording is currently being performed (see S3 in FIG. 3). In the above example, since the video camera device 1 has not yet recorded, the control unit 11 denies the determination in step S3.
[0023]
Then, the control unit 11 sets during recording (that is, the recording mode is set, see S4 in FIG. 3). Next, the control unit 11 starts a recording operation (see S5 in FIG. 3 and S in FIG. 5).
[0024]
At this time, the scenery (subject) in the vicinity of the start time of the student race is converged by the lens of the camera unit 4, and the converged image is converted into bitmap format data by the CCD of the camera unit 4.
[0025]
The data passes through the control unit 11 and is stored as recorded data in a storage part in the storage unit 10.
[0026]
Next, the control unit 11 determines whether or not the delete button 6 has been pressed (see S6 in FIG. 4). In the above example, since the user has not pressed the delete button 6, the control unit 11 denies the determination in step S6.
[0027]
In the above example, since the user has not pressed the cancel button 7, the control unit 11 denies the determination of “whether the cancel button 7 is on” (see S7 in FIG. 4).
[0028]
Next, the control unit 11 returns to immediately before step S1 in FIG. In this way, the control unit 11 repeats the operations of steps S1 to S7. As a result, the recording data is accumulated and stored in the storage unit 10.
[0029]
If the user's child is not yet at the starting point of the competition while the above recording operation continues, the user operates the delete button 6 for the first time (presses the button) to delete the useless recording. I).
[0030]
At this time, the controller 11 affirms the determination of “whether or not the erase button 6 is turned on” (see S6 in FIG. 4). Then, the control unit 11 causes the storage unit 10 to delete the recorded data (see S8 in FIG. 4).
[0031]
At this time, the storage unit 10 stores the time from the recording start time S (see FIG. 5) to the first operation time A (see FIG. 5) of the delete button 6 (this is called elapsed time). Delete recorded data.
[0032]
That is, when the delete button 6 is operated after the start of recording (S), the control unit 11 causes the storage unit 10 to delete the recorded data stored for a predetermined time. The predetermined time is, for example, the time from the recording start time S (see FIG. 5) to the first operation time A (see FIG. 5) of the delete button 6.
[0033]
Next, the control unit 11 causes the storage unit 10 to store a new recording position (that is, the first operation time point A) (see S9 in FIG. 4).
[0034]
Then, the control unit 11 denies the determination of “whether or not the cancel button 7 is turned on” (see S7 in FIG. 4). This is because the user has not pressed the cancel button 7.
[0035]
Next, the control unit 11 returns to immediately before step S1. And the control part 11 repeats operation | movement of step S1-S7. As a result, the recording data after the first operation time point A is accumulated and stored in the storage unit 10.
[0036]
Assume that the user operates the erase button 6 for the second time when the user's child is not yet at the start point when the recording operation continues.
[0037]
At this time, the control part 11 denies determination of step S6, and makes the memory | storage part 10 delete recording data (refer S8 of FIG. 4). Then, the storage unit 10 erases the recorded data stored in the time period from the first operation time point A of the erase button 6 to the second operation time point B of the erase button 6 (this is called a predetermined time).
[0038]
Next, the control unit 11 causes the storage unit 10 to store a new recording position (see S9 in FIG. 4).
[0039]
And the control part 11 negates step S7, returns to immediately before step S1, and repeats operation | movement of step S1-S7. As a result, the recording data after the second operation time point B is accumulated and stored in the storage unit 10.
[0040]
Similarly to the above-described operation, it is assumed that the user operates the delete button 6 at the third operation time point C (see FIG. 5). At this time, the storage unit 10 erases the stored recording data during the time from the second operation time point B of the erase button 6 to the third operation time point C (referred to as a predetermined time).
[0041]
Similarly, it is assumed that the user operates the delete button 6 at the fourth operation time point D (see FIG. 5) while the recording operation continues. At this time, the storage unit 10 erases the stored recording data during the time from the third operation time point C of the delete button 6 to the fourth operation time point D (referred to as a predetermined time).
[0042]
The features of the above operation will be summarized. When the delete button 6 is operated, the control unit 11 causes the storage unit 10 to delete the recorded data stored at a predetermined time. At this time, the predetermined time is a time from the Nth (N is an integer of 1 or more) operation of the delete button 6 to the (N + 1) th operation time.
[0043]
In this way, for example, immediately after the fourth operation time point D, if the user's child starts a running race, the video camera device 1 does not perform unnecessary recording (for example, a necessary part (for example, (Only scenes where my child is running) can be recorded.
[0044]
Thereafter, if the user turns off the recording button 8, the control unit 11 denies step S1, stops the recording operation, and enters a standby state.
[0045]
If the determination in step S1 is affirmed and the determination in step S3 is affirmed, the control unit 11 cancels the recognition that recording is in progress (see S10 in FIG. 3), and stops the recording operation (see S11 in FIG. 3). reference).
[0046]
Unlike the above description, when the user operates the delete button 6 at the second operation time point B, the control unit 11 slightly changes from the first operation time point A of the delete button 6 to the second operation time point B. The recorded data for the time (referred to as a predetermined time) until the earlier time B-1 (see FIG. 5) may be deleted.
[0047]
For example, when the user's child starts to run slightly earlier than the second operation time point B, it is assumed that the user operates the delete button 6 at the second operation time point B.
[0048]
At this time, the recorded data from the first operation time point A to time B-1 is erased, but the recorded data after time B-1 is continuously stored. As a result, it is possible to record a scene from when the user's child starts to run until it finishes running.
[0049]
That is, the predetermined time for deleting the recorded data may be a time from the Nth (N is an integer of 1 or more) operation of the delete button 6 to a time (B-1) earlier than the (N + 1) th operation time.
[0050]
Further, it is conceivable that the user's child starts running after the first operation time point A, and the user erroneously presses the erase button 6 at the second operation time point B. In this case, it is assumed that the user operates (presses) the cancel button 7 after the second operation time point B.
[0051]
At this time, the control unit 11 affirms the determination of “whether or not the cancel button 7 is on” (see S7 in FIG. 4). Then, the control unit 11 returns the recording position (see S12 in FIG. 4). That is, the control unit 11 returns (returns) the recording position to the first operation time point A. Next, the control unit 11 restores the recorded data (see S13 in FIG. 4).
[0052]
The features of the above operation will be summarized. A cancel button 7 is provided. It is assumed that the cancel button 7 is operated after the (N + 1) th operation time (for example, time B) of the delete button 6. The control unit 11 restores the recorded data from the Nth operation time point (for example, time point A) of the delete button 6 to the operation time point B-2 of the cancel button 7.
[0053]
As a result, the recording data after the Nth operation time point (for example, time point A) is restored and stored in the storage unit 10. Therefore, even if the user accidentally presses the delete button 6, since the recorded data after the time point A is stored, it is possible to record the scene from the start of the child of the user until the end of the run.
[0054]
Note that when the video camera device 1 is connected to a television and the user presses the play button 9, the recorded data is reproduced by the television. As a result, the user or the like can view the scene from when the user's child starts to run until the user finishes running on the television. Further, as described above, since the useless recording data is deleted, it is possible to avoid watching the useless scene where the child does not appear.
[0055]
