2. Description of the Related Art Conventionally, in an editing apparatus of this type, a time code reproduced from a video tape is taken together with a video / audio signal reproduced from a video tape, and a desired video / audio signal is reproduced based on the time code. A part can be registered as a clip and an edit list can be created.

In video tapes, NTSC
(National Television System Committee) A video / audio signal of 0 to 29 frames per second is recorded / reproduced based on a frame frequency (29.97 [Hz]) specified by the system. However, in this case, since the video and audio signals are recorded and reproduced on the video tape with a shift of 1.8 frames every minute, the time code is advanced by two frames every minute (that is, "59 seconds 29 frames"). There is a so-called drop frame mode in which correction is made to "00 second 02 frame" and the control is stopped so that the correction is stopped every 10 minutes. On the other hand, there is a so-called non-drop frame mode in which the time code is not corrected in the time code control.

[0006]

In this type of editing apparatus, the time code reproduced from the video tape is different between the drop frame mode and the non-drop frame mode. The video / audio signal reproduced from the video tape together with the time code can be captured and edited.

However, in this editing apparatus, when capturing a video / audio signal and a time code reproduced from a video tape, the operator sets a drop processing mode or a non-drop frame mode corresponding to the drop frame mode of the time code. The corresponding non-drop processing mode had to be set, and there was a problem that it was not easy to use.

[0008] The present invention has been made in view of the above points, and it is an object of the present invention to propose an editing apparatus which can greatly improve the usability.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a time code is assigned to each frame image based on a video signal based on predetermined information recorded together with the video signal on a video tape. A detection unit for detecting the mode and a setting unit for setting the processing mode to a mode corresponding to the time code addition mode based on the detection result of the detection unit are provided.

As a result, it is possible to set the processing mode corresponding to the time code addition mode without requiring the operator to set the processing mode unlike the conventional editing apparatus.

Is displayed on the main screen 30 and information of the drop frame mode or the non-drop frame mode is read from the registry and stored in the RAM 22 so that the video tape loaded in the video tape recorders 14A to 14D is read. An operation corresponding to the same drop frame mode or non-drop frame mode is executed.

The CPU 20 displays a preset time code, for example, “00: 00: 00: 00” on the time code display section 66 displayed on the left side of the input time code window 65.
Display the time code consisting of the initial setting value of.

At this time, in the input time code window 65, when the up button 66A or the down button 66B corresponding to the time code display section 66 is clicked or pressed by a mouse operation, the time displayed on the time code display section 66 is displayed. You can change the code.

After the operator changes the time code displayed on the time code display section 66 to a desired value (for example, "00: 59: 59: 00"), the operator changes the time code, for example, to the keyboard 1
By pressing the enter key (5), the time code can be determined.

By the way, at this time, for example, "00: 59: 59: 00" is set between the minute and the second of the time code determined to execute the operation corresponding to the drop frame mode.
To display a colon like When the operation corresponding to the non-drop frame mode is being executed, a dot is displayed between the minute and the second of the time code, for example, "00: 59.59: 00".

The input time code window 65
Then, when the time code of, for example, “00: 00: 00: 00” is displayed on the time code display section 66 as described above, when the deletate (Delete) key of the keyboard 15 is pressed, for example, The time code displayed at 66 can be erased, and a desired time code can be designated and input via the keyboard 15.

When a time code is designated and input via the keyboard 15, an integer of "0" to "9", a colon (":"), a dot ("."), And a plus ("+")
And minus ("-") can be used. However, plus and minus cannot be specified at the same time. If the time code is set to, for example, "00: 59: 5
9:00 ", enter" 00: 59: 59: 00 ",
"59:59:00""59:5900" and "595900" can be specified and input in various forms. Even if such various values are specified and input, the time code is determined after this Then, as described above, in the drop frame mode, "00: 5
9:59:00 "on the time code display section 66 and" 00: 59.5 "in the non-drop frame mode.
9:00 "on the time code display section 66.

The input time code window 65
In the drop frame mode, when a time code that should be corrected, such as "00: 01: 00: 00", is designated and input via the keyboard 15, this is displayed on the time code display section 66. Thereafter, by determining the time code, the time code ("00: 01: 00: 02") corrected according to the drop frame mode can be displayed on the time code display section 66.

Further, the input time code window 6
5, the time code is displayed on the time code display section 66 as "0
0: 59: 59: 00 ”is displayed (before confirmation), for example, if“ +1: 00 ”or“ +100 ”is specified and input via the keyboard 15 and confirmed, the displayed time code is displayed. Add the specified input value and add the result ("01: 00: 0
0:00 ”) can be displayed on the time code display section 66. Incidentally, when the value to be designated and input via the keyboard 15 is indicated by "-", the designated and input value is subtracted from the time code displayed by confirmation, and the subtraction result is displayed on the time code display section 66. Can be done.

In the input time code window 65, when the tab (Tab) key of the keyboard 15 is sequentially pressed, an OK button 67, a cancel button 68, a help button 68, and a time code display section 66 are displayed in the window. The focus can be cyclically moved so as to move the focus again to the time code display section 67 via the button 69.

In the input time code window 65, after the time code is determined, the keyboard 1
When the user presses the tab key 5 to focus on the OK button 67, and then presses the enter key on the keyboard 15, the time code is moved to, for example, the top position of the time scale 35A on the main screen 30 to make it an edit list. The input time code window 65 can be closed as well as being registered as a time code representing the start point of the editing process.

The input time code window 65
Then, when the time code displayed on the time code display section 66 is determined as shown in FIG. 10A, it is determined whether or not the time code is an erroneous value at that time, and based on the determination result, the time code value is determined. If an error is made, the display color of the time code display section 66 is inverted as shown in FIG. 10B and the operator can easily recognize the sound by sounding.

Incidentally, when it is determined whether or not the time code is an erroneous value, if the time code is set to hour: minute: second: frame, the time is correct only when the time is larger than 0 and smaller than 23. Is determined to be correct only when the minutes and seconds are greater than 0 and less than 59, and further, the frame is determined to be correct only when the frame is greater than 0 and less than 29.

The input time code window 65
In advance, the time code input range (range) is set to 5
It can be specified as less than a frame or more than 4 hours. If a time code is input beyond this range, it is determined to be an incorrect value.

(4) Frame Control Mode Detection Processing Procedure Here, when the editing apparatus 1 is activated, the CPU 20 actually executes the frame control mode detection processing procedure R shown in FIG.
T1 starts at step SP1 and continues at step S
At P2, it is detected via the system control unit 4 whether or not a video tape is loaded in each of the video tape recorders 14A to 14D, and the video tape is stored in one of the video tape recorders 14A to 14D used for editing processing. When loaded, the video tape recorder 14A-1
By transmitting a mode read signal to the 4D, the time code recorded at a predetermined address of the video tape loaded therein is read from the video tape recorders 14A to 14D.

Next, the CPU 20 proceeds to step SP3, and based on the time code given from the video tape recorders 14A to 14D via the system control unit 4,
It is determined whether the time code is recorded on the video tape loaded in the video tape recorders 14A to 14D in the drop frame mode or the non-drop frame mode.

Incidentally, the time code recorded on the video tape is represented by a bit sequence of 32 bits. In the case of the drop frame mode, for example, the time code of "23: 59: 59: 29" is "Ox23595969". In the case of the non-drop frame mode, the same “23: 59: 59: 29”
"Will be" Ox23595929 ". The lower 8 bits of the time code recorded on the video tape represent the number of frames. In the case of the drop frame mode, for example, 29 frames (Ox69) are "1101001" (Ox6
9), and in the case of the non-drop frame mode, the same 29 frames (Ox29) are represented as “101001” (Ox29).

That is, the same code (29 frames) is compared between the time code recorded on the video tape in the drop frame mode and the time code recorded on the video tape in the non-drop frame mode. The difference is that a bit stands or a bit does not stand at the position of the lower 7 bits.

Therefore, the CPU 20 detects whether or not a bit is set at the lower 7 bits of the time code based on the time code given from the system control unit 4, thereby dropping the video frame onto the video tape. It is possible to determine whether the time code is recorded in the mode or the non-drop frame mode.

Then, the CPU 20 proceeds to step SP4 and stores the same information of the drop frame mode or the non-drop frame mode as the determination result obtained in step SP3 in the registry.

Subsequently, the CPU 20 proceeds to step SP5 to determine whether or not the editing device 1 has stopped. Here, obtaining a negative result in step SP5 means that in the editing apparatus 1, the video tape recorders 14A to 14D
Means that a desired part of the video signal and the audio signal supplied from is registered as a clip, or that various processes such as creating an edit list based on the registered clip are executed. Step SP2
And thereafter, the above-mentioned steps SP5-SP2-SP3-SP4 until a positive result is obtained in step SP5.
-Repeat the loop of SP5.

The CPU 20 then proceeds to step SP
If the editing apparatus 1 obtains an affirmative result by terminating and stopping various processes in step 5, the process proceeds to the next step SP6, where the frame control mode detection processing procedure RT1 is performed.
To end.

(5) Frame Control Mode Processing Procedure In a state where the information of the drop frame mode or the non-drop frame mode is stored in the registry, the CPU 20 displays the screen 30 displayed on the display 12.
When the input time code window 65 is displayed on the main screen 30 by selecting the execution menu 64 by mouse operation, the frame control mode processing procedure RT2 shown in FIG.
Begin at P10.

Then, the CPU 20 proceeds to step SP11, reads out the information of the drop frame mode or the non-drop frame mode stored in the registry from the registry, and stores it in the RAM 22 so that the video tape recorders 14A to 14D. A drop processing mode corresponding to the same drop frame mode or a non-drop processing mode corresponding to the non-drop frame mode as the video tape loaded in the video tape is set, and an operation corresponding to this mode is executed.

Thereafter, the CPU 20 proceeds to step SP12 and determines whether or not the input time code window 65 has been closed. Obtaining a negative result in step SP12 means that the time code setting process is in progress and the input time code window 65 has not been closed yet. At this time, the CPU 20 proceeds to step S12.
Proceeding to P13, it is determined whether an initial set value of the time code to be displayed on the time code display section 66 has been set in advance.

Here, obtaining a negative result in step SP13 means that the time code is not displayed on the time code display section 66 because the initial setting value of the time code is not set in advance. The CPU 20 proceeds to step SP14 and determines whether the up button 66A or the down button 66B corresponding to the time code display section 66 is clicked by operating the mouse.

Here, obtaining a negative result in this step SP14 means that the up button 66A or the down button 66B corresponding to the time code display section 66 has not been clicked or depressed.
In step SP15, the process proceeds to step SP15 to determine whether or not the key designated and input via the keyboard 15 for specifying the time code is valid.

Here, obtaining an affirmative result in step SP15 means that “0” to “0” set in advance as described above.
This means that a key such as an integer “9” has been designated and input via the keyboard 15, and at this time, the CPU 20 causes the time code display section 66 to display the time code designated and input via the keyboard 15, After this step SP
Proceeding to 16, it is determined whether the enter key and / or the tab key of the keyboard 15 has been pressed or the focus has been removed from the time code display section 66.

Here, to obtain an affirmative result in step SP16, the time code is determined by pressing the enter key of the keyboard 15 in a state where the focus is on the time code display section 66, or the tab key of the keyboard 15 is pressed. By being pressed, the focus is removed from the time code display section 66, which means that the time code has been determined. At this time, the CPU 20 proceeds to step SP17 to determine whether or not the determined time code has an incorrect value. I do.

If the CPU 20 obtains a negative result because the value of the time code is correct in step SP17, the CPU 20 proceeds to the next step SP18 and selects the frame control mode set in step SP11 from the drop frame mode or the non-drop frame mode. Is determined.

Here, obtaining a positive result in step SP18 means that the frame control mode is set to the drop frame mode. At this time, the CPU 20 proceeds to step SP19 and displays the time code on the time code display section 66. If a colon is displayed between the minute and second of the time code being displayed, it is replaced with a dot and displayed, and if the time code is supposed to be corrected, this is corrected and displayed, and Display the time code according to the top frame mode.

On the other hand, obtaining a negative result in step SP18 means that the frame control mode is set to the non-drop frame mode. At this time, the CPU 20 proceeds to step SP20 to display the time code. If a dot is displayed between the minute and second of the time code displayed in the section 66, it is displayed by replacing it with a colon, and if the time code has already been corrected, it is displayed by canceling it. Let
Thus, the time code is displayed according to the non-drop frame mode.

Then, the CPU 20 returns to the step SP12, registers the time code and closes the input time code window 65 by pressing the enter key of the keyboard 15 with the focus on the OK button 67. Is obtained, thus proceeding to step SP21 to end the frame control mode processing procedure RT2.

Obtaining an affirmative result in step SP13 means that the preset initial value of the time code is displayed on the time code display section 66. At this time, the CPU 20 proceeds to step SP22. The initial value of the time code is temporarily stored in the main control section 3, and thereafter, the process proceeds to step SP14, where the initial value of the time code is displayed on the time code display section 66.

Obtaining an affirmative result in step SP14 means that the up button 66A or the down button 66B is clicked or pressed by a mouse operation with the time code display section 66 displaying the initial set value of the time code. That is, at this time, the CPU 20 proceeds to step SP23, and performs the up button 66A by operating the mouse from the temporarily stored initial value of the time code.
Alternatively, a time code that is changed when the down button 66B is clicked or pressed is calculated, and the calculated time code is displayed on the time code display unit 66.

Further, obtaining a negative result in step SP15 means that the key designated and input via the keyboard 15 is inappropriate, and the CPU 20
Returns to step SP14.

Further, obtaining a negative result in step SP16 means that the time code displayed on the time code display section 66 has not been determined, and that there is still a change to the time code.
Returns to step SP15.

Further, obtaining a positive result in step SP17 means that the determined time code has a value outside the preset range as described above and is incorrect, and at this time, the COU 20 corrects the time code. Is required, the process returns to step SP15.
