Description

[Detailed description of the invention] The present invention relates to an editing device.

Recently, an editing device as shown in FIG. 1 has been proposed.

In Figure 1, 2 is a central processing unit (CPU) as a control unit, 3 is a read-only memory (ROM) that contains software and is used for reading only and outputs to the CPU 2, and 4 is a 128-bit memory, for example. Edit number that stores which one of register B ₁ , register B ₂ , ..., register B ₁₂₈ as data area corresponding to each editor is called or is being called into register A as work area. Indicates a register.

Each of these registers B ₁ , B ₂ , ..., B ₁₂₈ contains the reel number (A
- Edit mode type (assembly mode or insert mode), source type (e.g. VTR, camera), editing start point (IN point) and editing end point (OUT point),
The editing start point (IN point) of the audio signal is memorized to be useful for editing. registers such as
Bi (i=1, 2, . . . , 128) is called to register A as a work area in a predetermined case so as to participate in the editing operation. In other words, these registers store data stored in any register.
It functions as a random access memory that is read or written according to the register specification by the CPU 2.

Reference numeral 5 designates a key block for the editor to issue commands, and the commands from the key block 5 enable desired commands to be transmitted to the CPU 2 via the key interface 6. 7 indicates a display block that displays information necessary for editing such as reel number and time code, and this display block 7 includes a CPU
A display signal is transmitted from the display interface 8 from the display interface 8.

9 indicates a recording VTR, 10, 11,..., 19 indicates a reproduction VTR, and these VRs 9, 10, 1
1,...,19 are VTR interfaces 20,2
1, . . . , 30 to be connected to the CPU 2.

Therefore, by using the reproducing tape cassettes loaded in the reproducing VTRs 10, 11, . . .
By operating the VTR and the recording VTR 9 simultaneously, it is possible to sequentially perform editing operations from a desired editing start point to an editing end point.

However, such tape to
Tape) editing equipment is configured so that the playback VTR and recording VTR operate simultaneously based on the input data during actual editing, so it was not possible to create an edited collection with the playback VTR in still image mode. . In addition, inserting still images from a camera requires a lot of effort, and obtaining still images from a video disk requires a very expensive system, as well as the disadvantage of using so-called tape to tape. There was an inconvenience that this work had to be done separately from the editing work (to Tape). On the other hand, with the advent of VTRs with dynamic tracking and the availability of time base corestas at low cost, the video signal output from the player in still image mode was previously incomplete and impractical. It became possible to create a signal that was sufficient for recording.

In view of the above, the present invention aims to provide an editing device that has the same operation as normal editing and has a function that allows editing in still image mode using the same system.

An embodiment of the editing apparatus of the present invention will be described below with reference to FIG.

When entering execution editing, first compare the editing start point PIN and editing end point POUT data set for the player on the playback side, and if they are equal, it is determined that still image execution is specified. Edit still images by stopping the VTR 10 as a player in the playback state at the editing start point, and stopping the VTR 9 as the recorder at the pre-roll point, then turning it into play mode and advancing the tape to the cut-in point. Make sure to do it.

On the other hand, the above-mentioned editing start point P _IN and editing end point P _OUT
If the data are not equal, it is determined that the execution is not a normal still image, and the player side 10 is stopped at the pre-roll point, and the recorder side 9 is also stopped at the pre-roll point, and then the player side 10 and the recorder side 9 are put into the play state. It operates as a normal editing mode in which the tape advances to the cut-in point.

The operation after determining whether it is the cut-in point or not is the same in both still image editing and normal mode editing.When the cut-in point is reached, the cut-in operation is performed, and when the cut-out point is reached, the cut is made, and then, for example, 2 seconds after that, the operation is the same. Later, the tape will be stopped and editing of the unit editor will be completed. Here, in the normal mode, the editing point data is determined by the data of the editing start point on the playback side and the recording side, and the editing end point on either side, but in the still image mode, the editing point data is determined by the data on the editing start point on the playback side and the editing end point on either side. Since the fact that the end point data are equal is used for determination, the true editing end point is separately defined and used as the designation of the cutout operation point.

As described above, according to the editing device of the present invention, in addition to the normal mode, there is a control routine for the still image mode, and the control routine can be switched at the appropriate time. In addition to editing, you can also edit still images. Therefore, still image editing can be performed easily and inexpensively using the same operations as normal editing.

It goes without saying that the present invention is not limited to the above-mentioned embodiment, and that various other configurations may be adopted without departing from the gist of the present invention.

Claims (1)

[Scope of Claims] 1. A playback device that plays back a video signal from a first recording medium; a recording device that records the video signal played back by the playback device on a second recording medium;
In an editing device including a control device that controls operations of the playback device and the recording device, the control device includes data indicating an editing start point on the first recording medium and editing on the first recording medium. storage means for storing data indicating an end point, data indicating an editing start point on the second recording medium, and data indicating an editing end point on the second recording medium; Comparing means for comparing data indicating an editing start point on a first recording medium with data indicating an editing end point on the first recording medium; control means for controlling the playback device and the recording device based on the data, and data indicating an editing start point on the first recording medium and data indicating an editing end point on the first recording medium. If they are equal, the playback device controls the playback device to play the still image at the editing start point on the first recording medium, and also controls the playback device to play the still image played back by the playback device to the recording device. The editing device is configured to control the recording device so as to record from an editing start point on the second recording medium.
