[0034]
Next, the operation of the imaging apparatus according to the present embodiment will be described. Here, a case where the first recording medium is a disk which is a rotating recording medium and the second recording medium is a semiconductor memory card will be described.
[0035]
FIG. 7 is a flowchart showing the operation of the imaging apparatus according to the present embodiment.
In S1, the state of the mode switch 60 is checked. If it is the recording mode, the process proceeds to S2, if it is the reproduction mode, the process proceeds to B (S20) in FIG. 10, and if it is the OFF mode, the process ends in S9.
[0036]
<Recording mode>
In S2, a basic function as a normal camera as a recording mode is operated. Specifically, it is confirmed that the power supply 86 is in a normal state, and the photographing conditions such as the presence / absence of the recording medium (disk) 33 and whether the recording medium has sufficient free space are satisfied. In addition, the focus and zoom of the lens 10 are appropriately driven according to the operation 70 of each part of the operator, and exposure control and focus adjustment are performed to expose the image on the image sensor.
[0037]
An analog signal from the image sensor 14 is AD converted (AD converter 16) and further converted into a video signal by the image processing unit 20. The converted video signal is output to the image display unit 28 for display. Further, the video signal is compressed by the image compression unit 32 in order to reduce the amount of data. The compressed image data is converted into an appropriate format for recording on a recording medium (disc) 33.
[0038]
In S3, based on the state of the trigger switch 64, the system control unit 50 determines whether the state is a shot state or a pause state. FIG. 8 is a timing display of the recording operation by the operation of the trigger switch 64 during photographing and the state associated with the Pause operation.
[0039]
FIG. 8A shows whether the operation mode of the main body is in the recording mode (REC) or the playback mode (PLAY). Here, the recording mode will be mainly described. The playback mode will be described separately. FIG. 8B shows a recording state (Shot) or a pause state (Pause) by operating the trigger switch 64. Here, every time the trigger switch 64 is pressed, the recording state (Shot) and the pause state (Pause) are alternately changed. For the sake of explanation, the Pause state is represented by P and the shot state is represented by the letter S, and numbers such as 1_1 and 1_2 are assigned as subscripts. Since there are two REC states in FIG. 8A, the number of the REC state is associated with the number on the left side of the subscript.
[0040]
The number on the right side at the time of attachment corresponds to the number of times of the push state or the shot state in each of the first REC state and the second REC state. For example, P1_2 indicates the second puas in the first REC state. FIG. 8C shows a recording state on the card in conjunction with the Shot / Pause state, and in the recording mode, a moving image is written on the card in the Pause state. The file created at this time is a PT (Pause_tmp) file. The subscript after the character PT is made to correspond to the meaning at the time of subscript in FIG. That is, PT1_2 indicates that the file is generated in the first REC state and in the second pose. FIG. 8D shows a recording state on the disc linked to the Shot / Pause state, and shows that a moving image is written on the disc at the time of Shot.
[0041]
The generation of a Pause file will be described in detail with reference to FIG.
When recording one cut scene (from recording mode start to recording mode end), when the number of pauses is large, when the pause time is long, or when the recording capacity to the card is small, the recording capacity of the card is insufficient. It is not possible to record all Pause images. Therefore, deletion is overwritten in order from the oldest one.
[0042]
FIG. 9A shows a state in which the N-1th Pause file is recorded and the recording area of the card is full. When the N-1th Pause file is continuously written, the PT1_1 and PT1_2 portions are overwritten as shown in FIG. 9B. When further adding the Pause file for the Nth time, the hatched portion of FIG. 9B is overwritten on the portions PT1_3 and PT1_4 as shown in FIG. 9C.
[0043]
Returning to FIG. 7, if the determination in S3 is Shot, the recording medium disk 33 is rotated in S7, the image data is recorded on the recording medium disk in S8, and the process returns to A. If the determination in S3 is Pause, it is checked in S4 whether the card 200 has a recording capacity sufficient for recording a predetermined amount of data. If there is no free space exceeding the predetermined amount, the card is in the first state. Return to A. That is, although it is in the Pause state, recording on the card is not performed. If there is free space of a predetermined amount or more in S4, the card is assumed to be in the second state, and the rotation of the recording medium disk 33 is stopped in S5, the image data is recorded on the card recording medium 2 in S6, and the process returns to A.
[0044]
Next, the case where the playback mode is determined in S1 will be described with reference to FIG.
In step S20, the card 200 is read, and it is checked whether there is a newly created pause file. If there is no new pause file, the basic function for normal playback is operated in S21. Specifically, it is confirmed that the state of the power source 86 is normal and the reproduction conditions such as the presence or absence of the recording medium (disc) 33 are met. Then, the recording medium (disk) 33 is rotated according to the operation 70 of each part of the operator, and a desired image is read from the recording medium 33. Since the read data is compressed, it is expanded via the compression / decompression circuit 32 and displayed on the image display unit 28.
[0045]
If there is a new Pause file at S20, the operator is prompted to determine whether or not to restore and write the file created at the time of pause, that is, at pause, to the disk at S22. In this case, a message to that effect is displayed on the display unit 28, and the operator's intention is determined by operation using the operation unit 70 or the like. If the restore operation is not necessary, the basic reproduction operation is performed in S21 and the process returns to B.
[0046]
If a restore operation is required in S22, a representative screen of a new Pause file is displayed in a list on the image display unit 28 in S23. An example of this screen is shown in FIG. Here, the operator selects a Pause file image to be restored.
[0047]
FIG. 11 is an example of a screen for selecting a necessary recording scene by reducing and displaying a plurality of temporarily stopped moving image files stored on the card. An image surrounded by a thick frame is a selection frame indicating a selection state. The selection frame is moved left and right and up and down by operating the operation unit 70 (FIGS. 1 and 6), and a desired image is selected and determined (decision key pressed).
[0048]
The representative screen may be an image at the beginning of each Pause file, or may be a relatively small image called a thumbnail image attached to the file. These are read from the card 200 as data, and are decompressed by the compression / expansion circuit 32 as necessary and displayed on the image display unit 28. In S24, the display of the selected file is switched as shown in FIG. 12, and a representative image of the file is displayed.
[0049]
FIG. 12 is an example of a screen display for reproducing the image selected above as a moving image and selecting a portion to be transferred to the disk in the reproduction scene.
Reference numeral 300 indicates a moving image display unit, 301 indicates a time axis display unit, and a cursor 302 indicates where the image reproduced and displayed in 300 is in time for one moving image cut scene. Reference numerals 303 and 304 indicate selected portions in the moving image of one cut scene. The thick line portions 303 and 304 are selected portions, which are transferred and recorded on the disc. Reference numeral 305 denotes an operation state such as playback, pause, or fast forward. It is a general one in which a portion corresponding to an operation is displayed by blinking.
[0050]
During playback display, the trigger switch 64 is operated to designate a portion to be recorded on the disc and a portion not to be recorded. That is, in the restore mode, a necessary image instruction (transfer to disk) and an unnecessary instruction (deleted later) are performed by operating the trigger switch 64 that is a toggle switch.
[0051]
In S25, the recording medium disk 33 is rotated. In S26, it is determined whether or not the reproduction has been performed to the end of the file. If the file has not been reproduced to the end in S26, the moving image is reproduced in S27. In this case, data is continuously read from the card 200 and decompressed. In S28, a determination is made based on the operation state of the necessary image instruction (transfer to disk) and the unnecessary instruction (deleted later) by operating the trigger switch 64 which is the toggle switch described above.
[0052]
FIG. 13 is a timing display of the status regarding the transfer from the card to the disk accompanying the operation of the trigger switch 64 during the restore operation.
FIG. 13A shows whether the operation mode of the main body is in the recording mode (REC) or the reproduction mode (PLAY). Since the restoration is performed in the reproduction mode, the reproduction mode will be mainly described here. FIG. 13B shows a necessary image instruction state (transfer to disk) and an unnecessary instruction state by operation of the trigger switch 64. SEL1_1 and SEL1_2 correspond to necessary image instructions. FIG. 13C shows that in the playback mode, a moving image (here, PT1_2 file) is read from the card regardless of transfer / non-transfer. FIG. 13D shows the transfer recording operation from the card to the disk in conjunction with the state of FIG. That is, in this case, two scenes SEL1_1 and SEL1_2 are partially designated as necessary images in the PT1_2 file and transferred and recorded as P1_2_1 and P1_2_2, respectively. The transferred P1_2_1 and P1_2_2 are erased from the memory card.
[0053]
An unnecessary instruction state is set in the initial state by determining whether the image is in a necessary image instruction state (transfer to disk) or an unnecessary instruction state by operating the trigger switch 64. Then, when S28 is first passed in FIG. 10, since it is an unnecessary instruction state, recording on the recording medium disk 33 is stopped and the process returns to D in S29. When the process proceeds to the determination of S28 again, if the trigger switch has been operated up to that point and the image indication state required for recording on the recording medium disk 33 has been selected, the image reproduced in S30 is transferred to the disk and recorded. To do. Then return to D.
[0054]
If the end of the file is reached while repeating the processing from S26 to S29, 30, the process proceeds from S26 to the end. This completes the restore operation for one Pause file. If another new Pause file exists in the card 200, the process proceeds from S20 to S22, and the restore operation is processed in the same sequence.
[0055]
In this way, when the disc is normally reproduced after the restoration process, the restored image and the image recorded in advance at the time of photographing are sequentially reproduced in the order of time at the time of photographing. The order of files to be reproduced is described in a reproduction control file called a normal playlist. For example, when the P1_2 moving image taken at the timing of FIG. 8 is restored as shown in FIG. 13, files P1_2_1 and P1_2_2 are transferred to the disc and recorded.
[0056]
The subscript here indicates that the necessary image PT1_2 and PT1_2_2 have been transferred to the first recording medium as a result of the necessary image instruction (transfer to disk) and unnecessary instruction in the restore operation. Indicates. Therefore, when this disc is played, the order is S1_1 playback, P1_2_1, P1_2_2 playback, S1_2 playback, and so on. In this example, the subscript of the file name corresponds to the playback order. Actually, however, instead of managing the order by the file name, a management file is created by associating the file name with the playback order. It is something to regenerate. The above is the main operation sequence of this embodiment.
[0057]
<Other embodiments>
When one Pause file is played back by the restore operation, playback is performed up to the end of the file, but a cancel operation may be performed during playback. When a pause time is long, it is troublesome to reproduce until the end, and convenience can be improved by enabling cancellation when the necessary part is reproduced.
[0058]
Similarly, if fast forward, rewind, pause, etc. can be performed during playback, the convenience is further improved. However, on the other hand, the operation may be complicated, so that necessary functions may be provided according to the purpose and situation.
[0059]
As shown in FIG. 12, buttons such as buttons corresponding to play, fast forward, rewind, and pause are displayed on the display unit, which are realized by operating the cursor keys of the operation unit (FIG. 6) of the main body. It can be done.
[0060]
In the above embodiment, whether the second recording medium is in the first state or the second state is determined based on whether or not the free space of the card is a predetermined amount as a pause capacity, and the recording operation at the time of pause is performed. Has been decided.
[0061]
However, when a card is used for still image recording, there is not always a predetermined amount of free space. It seems that the operation is often different from when a completely unrecorded card is installed and after recording a large number of still image files, such as when the recorded image at pause can not be secured on the card, It is difficult to understand what the current state is, and the usability is bad. Therefore, a free space on the card may be designated and secured in advance as a pause capacity. In this case, the number of still images to be recorded is reduced by the amount of capacity for pause.
[0062]
However, the operator can select according to the purpose whether to give priority to the number of still images to be taken or to give priority to the restoration of video at the time of pause at the time of moving image recording. In this case, the pause capacity may be specified by a capacity such as “how many megabytes”, but may be specified by the number of recording seconds as a moving picture such as “how many seconds”.
[0063]
As described above, according to the above-described embodiment of the present invention, it is possible to improve the usability of original moving image shooting by attaching a memory card. With conventional systems, etc., usually you can cancel the pause early with a margin of the scene you want to shoot, or even if you want to shoot a little longer without taking a pause immediately after the scene you want to shoot, There was a tendency to make useless records.
[0064]
In the above embodiment, since the moving image at the time of the recording pause is recorded on the memory card, it is possible to easily enter the pause state without fear of missing. As a result, there is an effect that unnecessary recording is not performed on the first recording medium such as a tape or a disk, and the necessity for later editing is reduced. Further, according to the above-described embodiment, when the remaining recording capacity of the memory card is in the first state, it can be used as a normal imaging recording / reproducing device, and in the second state, the convenience is improved as described above. be able to.
[0065]
As described above, according to the present embodiment, the pose is normally canceled with a margin of the scene that the user wants to shoot normally, or the pose is not taken immediately after the scene to be shot is over, and the shoot is made a little longer. It is possible to eliminate the problems in the conventional system that cause unnecessary recording before and after the scene.
[0066]
Furthermore, according to the above embodiment, since it is not necessary to mount a large amount of memory in the main body in advance, the cost of the main body is not increased. Since a memory card is a system that can be mounted in the system in advance as a recording medium for still image data in recent video cameras and the like, a second memory card for recording a moving image at the time of recording pause is used. By using it as a recording medium, an increase in cost due to the addition of the recording medium can be avoided. In the above embodiment, this memory card is used not only for recording still image data but also as a second recording medium for recording a moving image at a recording pause, thereby improving the operability and convenience of the system. It was possible.
[0067]
In addition, according to the above embodiment, the determination as to whether or not to restore the moving image data at the recording pause is inquired when the moving image data at the pause is newly created. There is an effect that it is possible to avoid troublesome operations such as the confirmation operation and to reliably execute the restoration operation.
[0068]
Further, according to the above embodiment, when selecting moving image data during the recording pause, the same operation unit as that in the recording mode is used. There is a sense of unity of operation, and it is easy to remember the operation and has the effect of preventing erroneous operation. Furthermore, since they are the same operation unit, there is an effect that it is easy to realize downsizing and cost reduction of the device without increasing the number of operation members of the main body more than necessary.

Furthermore, according to the above-described embodiment, when a moving image is recorded on the memory card during the recording pause, the rotation of the disk 33 is stopped, so that there is an effect that unnecessary power is not consumed. In the case of a rotating recording medium such as the disk 33, there is a recording head or the like, but there is a possibility that the medium or the head may be damaged when vibration or impact is applied while the medium is rotating.
However, by stopping the rotation, the recording head can also be retracted, so the above problem can be avoided.
