Abstract

PURPOSE:To attain insert recording efficiently in any case by applying retrieval to be recorded in response to the changeover between the insert mode recording and other recording. CONSTITUTION:A recording means 107 is provided with a changeover means 119 recording of the insert mode recording or the normal mode recording other than the insert mode recording and a means 121 applying the retrieval of a block to be recorded in response to the changeover. Thus, in the case of setting the insert mode, it is possible to find out a free track before all tracks are searched when the insert mode is selected to apply free track search from the outer circumference of a video floppy 108. Thus, the search time is short. When the insert mode is released or the insert mode is set, initializing is applied automatically and free track is retrieved, then the required time till the next recording is decreased. Thus, the complete insert recording is executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording device that records in a plurality of memory blocks of a memory means.

[Conventional technology]

Conventionally, as an example of such a recording device, there is a recording device that records image signals by forming concentric tracks on a magnetic disk in accordance with the still video standard.

[Problem to be solved by the invention]

The above-mentioned apparatus has a recording mode called insert recording mode. This insert recording mode will be explained.

In FIG. 4, I) is 50 formed on the magnetic sheet 9.
FIG. 3 is a diagram illustrating an example of whether or not recording is performed on concentric tracks of FIG. In I), the numbers on the horizontal axis indicate track numbers.

These track numbers are sequentially numbered from the outer periphery of the magnetic sheet 9. In the example shown in ■), 1 to 4, 6 to 9.1
1. Tracks 13 to 15 are recorded tracks on which recording has already been performed; 5, 10. 12. Tracks after 16 are empty tracks on which no recording has been performed yet.

First, a mode other than the insert recording mode, for example, a normal mode, is a mode in which recording is performed on a track that satisfies the following conditions among empty tracks on the magnetic sheet 9, as shown in FIG. 4 (2). That is, this is a mode in which all tracks on the inner circumference side of the track of interest are empty tracks, and recording is performed sequentially on the outermost track among these empty tracks.

That is, as shown in Figure 4 (■), 16 tracks are recorded at first (indicated by (1)), 17 tracks are recorded next (indicated by (2)), and then in the order shown below. This is the mode for recording.

Next, the insert mode refers to a mode in which recording is performed in the sequence shown in FIG. 4 (■). That is, this corresponds to a mode in which recording is performed sequentially from the outermost track among the vacant tracks on the magnetic sheet 9.

That is, the present embodiment provides such an insert mode in order to be able to sequentially record all tracks on a magnetic sheet recorded in a so-called submerged state without leaving any empty tracks.

However, since the access position of the head is different between the normal mode and the insert mode, there is a problem in that insert recording cannot be performed completely even if the normal mode is switched to the insert mode.

The present invention aims to solve this problem.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention includes a recording means for recording in a plurality of memory blocks of a storage means, and a recording means for causing the recording means to perform either insert mode recording or normal mode recording other than insert mode recording. The apparatus includes a switching means, and means for searching for a block to be recorded by the recording means in response to switching of the switching means.

[For production]

In the above configuration, the means for performing the search performs the search in response to switching of the switching means.

The image sensor 104 of this embodiment is composed of a CCD,
The structure is as shown in FIG. 1, and with this structure, the FRAME image cannot be read out when an electronic shutter is used, that is, when COD light is not blocked by a mechanical shutter.

Also, to read the FRAME image, use the VCCD as shown in Figure 6.
This is possible if a COD with twice the number of cells as in Figure 1 is created, but even if a COD with the structure in Figure 2 is used, it requires memory, the configuration is complicated, and the cost is high. It will be up.

In FIG. 1, PD is a photodiode for photoelectric conversion, and VCCD is a vertical transfer COD that vertically transfers the signal obtained by the photodiode PD.

2 is controlled.

Next, the operation of this embodiment will be explained using FIGS. 2 and 3. 2 and 3 show flowcharts.

First, in Sl, check the open/closed state of the door,
If it is open, proceed to SL; if closed, proceed to S2. Next, in S2, the presence or absence of a video floppy is checked,
If there is no such information, proceed to Sl, and if there is, proceed to S3. Next, at 83, if the IN5ERT shown in the first diagram is ON, the process advances to S4, and if the IN5ERT shown in the first diagram is OFF, the process advances to S9. Next, in 84, FIELD
If recording is set, the process advances to S5, and if FRAME recording is set, the process advances to S7. Next, IN5ERT already in S5.

If FIELD mode has been initialized, SL
In S7, if the initialization of IN5ERT and FRAME mode has been completed, the process goes to Sll, and if not, the process goes to S8. Next, in S9, if normal initialization (when not in INSERT mode) has been completed, the process advances to Sll; if not, the process advances to SIO.

Next, if SWl is ON in Sll, go to S12, and O
If it is FF, proceed to Sl shown in FIG.

Next, in S12) if it is ICONT mode, 313
If the mode is other than HCONT, the process advances to S15.

Next, in 313, if the IN5ERT mode was set at S3, the process goes to S14, and at S3, IN5ERT mode is set.
If the ERT mode is not set, proceed to 515. Then, set the ICONT mode (which was set in S14) to L.
Change to CONT mode and proceed to S15. And S1
In step 5, AE, AF, AWB, etc. are detected, photographing parameters are set, and the process proceeds to S16. Next, 516i,
: If SW2 is ON, proceed to S17; if SW2 is OFF, proceed to S16. Next, in S17, if HCONT or LCONT is set, the process goes to S18;
If GLE or 5ELF is set, the process advances to S23 and recording is performed. If the process advances to S18, the process advances to S19 after photographing, and if the process advances to S23, the process advances to Sl after photographing. Next, in 319, if the mode is IN5ERT at S3, the process goes to S21, and if it is not the INSERT mode at S3, the process goes to S20.

Then, in S21, the head is moved by searching for an empty track that is innermost and outermost than the recording track that the head is currently on and that has finished recording, and then proceeds to S22. Then, in S20, 1
The head is advanced by the number of tracks (however, in the case of shooting in frame mode when using the frame head, the head is advanced by two tracks), and the process advances to S22.

Next, in S22, if SW2 is ON, the process advances to 318, and if SW2 is OFF, the process advances to Sl.

Note that S6 is initialization in the field of the insert mode, and initialization is started from the outer circumferential side (1) rack side of the video floppy and the head is sent to the outermost empty track.

S8 is initialization for the frame in the insert mode, in which an empty track search is performed from the outer circumferential side of the video floppy 108, and the head 107 is sent to a location where two empty tracks are lined up.

SIO is a normal initialization that is not in insert mode, and searches from the inner side to the outer side of the video floppy 108, and sends the head 107 to the track one track inside the first recorded track found (
However, the above example is for a field, and for a frame, the head 107 is sent to two tracks: a track one track inside the recorded track and a track one track inside the recorded track. Note that the head 107 is a frame head. ).

Also, S6. S8. If there is no free track on the video floppy 108 in SIO, this is displayed on the display LCD and swi and SW2 are not accepted. Also, S20. The same situation as described above occurs when there is no empty track in S21 and after recording is performed on the innermost track (the 50th track) where recording and playback is possible. Note that S18. S
23, in the case of HCONT, high-speed continuous shooting of field images using an electronic shutter, LCONT
is low-speed continuous shooting in either field recording mode or frame recording mode using mechanical shutter 102, 5INGL
E is single shooting of a frame or field image by the mechanical shutter 102, and 5ELF is self-timer shooting of field recording or frame recording by the mechanical shutter 102.

[Other Examples]

HCO only when FRAMH occurs at S14 in the first embodiment
NT may be automatically changed to LCONT and left as IC0NT during FIELD.

Also, if the S3 is in insert mode, the S3
4, automatically F without branching at FIELD and FRAME
As an IELD, S14 may not be performed.

As explained above, according to this embodiment, even if the ICONT mode is set (during the insert mode), the photographer can wait for a photo opportunity by switching to LCONT without accepting the ICONT mode. You can shoot the intended field and frame images without removing the image.

Furthermore, in this embodiment, as explained above, when the insert mode is set, an empty track search (initialization) is performed from the outer circumferential side of the video floppy, so an empty track can be found before all tracks are searched ( if there are free tracks). Therefore, the search time is short. Furthermore, when the insert mode is canceled or the insert mode is set, initialization is automatically performed and a search for an empty track is performed, so that the time required before the next recording can be shortened. Further, since a storage device such as a RAM is not required, cost reduction and size reduction can be achieved.

〔Effect of the invention〕

As explained above, according to the present invention, a search for recording is performed in response to switching between insert mode recording and other recording, so that recording can be efficiently performed in each block of the storage means in any case. can be done.
