[Problems to be solved by the invention]
As described above, in the above-described video camera device, since a video tape is used as a recording medium, only sequential recording can be performed. Therefore, in order to partially erase unnecessary recording data (that is, recording data stored at a predetermined time), a method of operating a rewind button, rewinding a video tape, and overwriting is used. As described above, there is a first disadvantage that the trouble of erasing unnecessary recording data is complicated.
[0005]
In addition, since the erasing operation is performed once all the recorded data is taken in, the second disadvantage is that the recorded data cannot be erased in real time (that is, almost simultaneously with the recording operation). Therefore, the present invention provides a video camera device capable of erasing unnecessary recorded data with one touch and in real time in consideration of such conventional disadvantages.
[0006]
[Means for Solving the Problems]
In order to solve the above problem, according to the present invention, a control unit, a camera unit, a storage unit, and an erase button respectively connected to the control unit are provided, and the storage unit is randomly accessed. When the delete button is operated after the start of recording, the control unit causes the storage unit to delete the recorded data stored for a predetermined time.
[0007]
In the present invention according to claim 2, the predetermined time is a time from a recording start time to a first operation time of the erase button, or a predetermined time from the Nth (N is an integer of 1 or more) operation time of the erase button. N + 1) The time up to the operation time.
[0008]
According to the third aspect of the present invention, the predetermined time is a time from the time point of the N-th operation (N is an integer of 1 or more) of the delete button to a time earlier than the time point of the (N + 1) -th operation.
[0009]
According to the fourth aspect of the present invention, when a cancel button is provided and the cancel button is operated after the (N + 1) th operation of the delete button, the control unit controls the Nth (N is 1 or more) of the delete button. (Integer) The recorded data from the operation time to the operation time of the cancel button is restored.
[0010]

The microphone 5 is connected to the casing 2. The delete button 6, the cancel button 7, the record button 8, and the play button 9 each include a key (switch) and the like, and are provided to be exposed on the surface of the casing 2.
[0013]
The storage unit 10 is configured to be randomly accessible. The storage unit 10 includes, for example, an HDD (hard disk driver), a DVD-RAM, and the like. The storage unit 10 is provided in the casing 2.
[0014]
Next, as shown in FIG. 2, the control unit 11 includes, for example, a CPU and the like. The delete button 6, the cancel button 7, the record button 8, and the play button 9 are each connected to a 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 data by the CCD of the camera unit 4 and input to the control unit 11.
[0016]
The reproduction unit 13 includes, for example, a signal processing unit. The recorded data stored in the storage unit 10 is input to the reproduction unit 13 via the control unit 11. The reproducing 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 device 1 is configured by the above components.
[0019]
Next, the operation of the video camera device 1 will be described mainly with reference to FIGS. For example, it is assumed that the user of the video camera device 1 is going to record a scene of a child's race in 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 ski race while looking through the viewfinder 3, and presses the recording button 8 to the ON state. The recording button 8 includes, for example, a toggle switch, and when pressed to the on state, the on state (energized state) is maintained. When the recording button 8 is pressed 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). Then, the control unit 11 causes the storage unit 10 to clear the storage data at the recording position (see S2 in 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 the recording (that is, sets the recording mode, see S4 in FIG. 3). Next, the control unit 11 starts the recording operation (see S5 in FIG. 3 and S in FIG. 5).
[0024]
At this time, the scenery (subject) near the start point of the race is converged by the lens of the camera unit 4, and the converged image is converted into bitmap data by the CCD of the camera unit 4.
[0025]
The data passes through the control unit 11 and is stored as recording data in a storage unit 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]
Further, in the above example, since the user has not pressed the cancel button 7, the control unit 11 denies the determination of “whether or not the cancel button 7 is on” (see S7 in FIG. 4).
[0028]
Next, the control unit 11 returns to just 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 start of the race during the above-described recording operation, the user operates the erase button 6 for the first time in order to erase useless recording (pressing). ).
[0030]
At this time, the control unit 11 affirms the determination of “whether or not the delete button 6 has been 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 point S (see FIG. 5) to the first operation time point 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, a 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 the new recording position (that is, the one at 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 has been 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. Then, the control unit 11 repeats the operations of steps S1 to S7. As a result, the recording data after the first operation time A is accumulated and stored in the storage unit 10.
[0036]
If the child of the user is not at the start point while the recording operation is continuing, the user operates the erase button 6 for the second time.
[0037]
At this time, the control unit 11 denies the determination in step S6 and causes the storage unit 10 to delete the recorded data (see S8 in FIG. 4). Then, the storage unit 10 deletes the recorded data stored in a time period from the first operation time point A of the delete button 6 to the second operation time point B of the delete button 6 (this is called a predetermined time).
[0038]
Next, the control unit 11 causes the storage unit 10 to store the new recording position (see S9 in FIG. 4).
[0039]
Then, the control unit 11 denies step S7, returns to just before step S1, and repeats the operations of steps S1 to S7. As a result, the recording data after the second operation time point B is accumulated and stored in the storage unit 10.
[0040]
It is assumed that the user operates the delete button 6 at the third operation time point C (see FIG. 5), similarly to the above-described operation. At this time, the storage unit 10 deletes the stored recorded data during a time period (a predetermined time period) from the second operation time point B to the third operation time point C of the delete button 6.
[0041]
Similarly, it is assumed that the user has operated the delete button 6 at the fourth operation time point D (see FIG. 5) while the recording operation is continuing. At this time, the storage unit 10 erases the stored recorded data in a time period (a predetermined time period) from the third operation time point C to the fourth operation time point D of the delete button 6.
[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 for a predetermined time. At this time, the predetermined time is a time from the N-th (N is an integer of 1 or more) operation time of the delete button 6 to the (N + 1) -th operation time.
[0043]
In this way, for example, assuming that the child of the user starts the race immediately after the fourth operation time point D, the video camera device 1 can perform the necessary portions (for example, Only the scene 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 affirmative, and the determination in step S3 is affirmative, the control unit 11 cancels the recognition that recording is in progress (see S10 in FIG. 3) and stops the recording operation (step S11 in FIG. 3). reference).
[0046]
Note that, unlike the above description, when the user operates the delete button 6 at the second operation time point B, the control unit 11 shifts the erase button 6 slightly from the first operation time point A to the second operation time point B. The recorded data up to a time (referred to as a predetermined time) up to an earlier time B-1 (see FIG. 5) may be deleted.
[0047]
For example, when the child of the user starts running a little earlier than the second operation time point B, it is assumed that the user has operated the erase button 6 at the second operation time point B.
[0048]
At this time, the recorded data from the first operation time A to the time B-1 is deleted, but the recorded data after the time B-1 is continuously stored. As a result, a scene from when the user's child starts running until the user finishes running can be recorded.
[0049]
That is, the predetermined time for erasing the recorded data may be the time from the Nth (N is an integer of 1 or more) operation time of the delete button 6 to the time (B-1) earlier than the (N + 1) th operation time.
[0050]
Further, it is conceivable that the child of the user starts running after the first operation time point A, and the user erroneously presses the delete button 6 at the second operation time point B. In this case, it is assumed that the user has operated (pressed) 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. Assume that the cancel button 7 is operated after the (N + 1) -th operation (for example, time B) of the delete button 6. The control unit 11 restores the recorded data from the N-th operation of the delete button 6 (for example, the time A) to the operation B-2 of the cancel button 7.
[0053]
As a result, the recording data after the N-th operation time point (for example, time point A) is restored and stored in the storage unit 10. Therefore, even if the user presses the erase button 6 by mistake, the recorded data after the time point A is stored, so that the scene from when the child starts running until the user finishes running can be recorded.
[0054]
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 running until the user finishes running on the television. Further, as described above, since the useless recorded data is deleted, it is possible to avoid viewing a useless scene where no child appears.
[0055]
