The data of the lyric image file and the illustration image file are transmitted from the personal computer 10 to the MT.
The data is output to the data tape 50, recorded on a data tape, and supplied to a synchronous editing apparatus described below using the data tape.

FIG. 2 is a block diagram of the synchronous editing apparatus according to the embodiment, and has the same CPU 1 as the image file generating apparatus of FIG.
0a ', a memory 10b', an I / F 10c ', and a peripheral device 10d'. Then, a synchronous editing process is performed based on the program installed on the hard disk of the memory 10b '. The data of the lyrics image file and the illustration image file to be synchronously edited are supplied from the MT 50 'connected to the I / F 10c'.

The personal computer 10 'includes a time code decoding circuit 4 for decoding a time code from the output signal of the DAT 6 into time code information.
A sub-code encoding circuit 5 for encoding sub-code information into a sub-code is connected, and a DAT tape on which a karaoke song and a time code are recorded is prepared in advance in the time code decoding circuit 4 so that it can be used for synchronous editing. A DAT 6 for reproducing a karaoke song (accompaniment and the like) and a time code is connected to the DAT 6, and an audio system 7 for monitoring the karaoke song is connected to the DAT 6. Further, a sub-code decoder 8 is connected to the sub-code encoding circuit 5, and a CRT 9 used as a monitor at the time of synchronous editing is connected to the sub-code decoder 8.

A synchronous editing console 1 is provided with a lever 11 operated by an editor to input a timing for changing the color of the lyrics image.
And a screen output switch 12 operated when outputting a lyric image and an illustration image. The lever 11 and the screen output switch 12 are connected to the A / D conversion circuit 2 and the I / D
It is connected to a personal computer 10 'via the O board 3.

FIG. 1 is a top view of the synchronous editing console 1.
An operation knob 11a of the lever 11 and a button 12a of the screen output switch 12 are provided on the panel surface. The operation knob 11a of the lever 11 is connected to a slide volume 11b disposed inside the operation console, and the operation knob 11a is capable of reciprocating movement between an end A and an end B shown in the drawing. Then, the editor operates the color change position by moving the operation knob 11a of the lever 11 back and forth.

The resistance value of the slide volume 11b changes according to the position of the operation knob 11a. The resistance value of the slide volume 11b is converted into a voltage value by a circuit (not shown) and output to the A / D conversion circuit 2. This A /
The CPU 10a 'outputs the output value of the D conversion circuit 2 to the operation knob 11.
It is taken in as position information of a. Note that the displacement amount of the operation knob 11a and the output voltage value have a linear relationship.
Further, since the voltage value at the end A and the voltage value at the end B are known in advance, the CPU 10a 'can operate the operation knob 11
It can be detected that a 'has become the end A or the end B of the reciprocating section.

FIG. 3 is a diagram for explaining the functions of the main parts of the synchronous editing apparatus. First, the DAT 6 performs audio reproduction of a karaoke song and also performs time code reproduction, and the time code decoding circuit 4 decodes the reproduced time code into time code information and outputs it to the CPU 10a '. Note that synchronous editing is performed while listening to the audio reproduction sound by the DAT 6 with the audio system 7.

On the other hand, the A / D conversion circuit 2 detects the position of the lever 11 of the synchronous editing console 1 (the position of the operation knob 11a) and outputs the position information to the CPU 10a '. It detects that the screen output switch 12 of the synchronous editing console 1 has been pressed and outputs it to the CPU 10a '.

The hard disk of the memory 10b 'has MT
The data of a lyric picture file and an illustration picture file for one tune supplied and reproduced at 50 'are stored.
10a 'selects the next screen in the memory 10b' to be output each time the screen output switch 12 is pressed. Also,
Based on the position information of the lever 11, a color change position, that is, a coordinate on a screen of a pixel which is a boundary of the color change on the screen is calculated, and a cursor is set at the position. Further, it is determined whether the lever 11 has reached the end portion A or the end portion B, and the timing of the line change of the lyrics image is set, and the cursor position is set to the position of the head of the next line of the lyrics. Furthermore, CPU
10a 'converts the image data of the screen on which the color change position is specified to the subcode information in order to display the image for the monitor. In addition, a time table is automatically generated and stored at the timing of screen output switching and the timing of color change, which are the operation results of the synchronous editing console 1.

The RAM of the memory 10b 'has a time table area for storing screen output timing and color change timing as time-series data in which one frame of a display image corresponds to one step, and a sub-code buffer. The area has been set. The MT 50 'reproduces the data of the lyrics image file and the illustration image file supplied to the memory 10b', and records the data of the time table which records the timing of the screen output switching and the color change timing.

The subcode encoding circuit 5 converts the subcode information generated by the CPU into a subcode format, and the subcode decoder 8 decodes the subcode and outputs a video signal. Then, the image on the monitor screen is reproduced on the CRT 9 and used for checking the contents at the time of editing.

The time table is composed of a storage area corresponding to each step in which one frame (1/30 second) of a display image is defined as one unit time, and stores a screen number of an output screen and data of a color change position. It is. That is, when screen output is performed by operating the screen output switch 12, the screen number of the output screen is written in the storage area of the step corresponding to the timing at that time. Also, in response to the operation of the lever 11, the color change width (the number of pixels) from the head of the lyrics to the color change position (cursor position) is written together with the line number. Furthermore, lever 11
When the operation knob 11a is at the end A or the end B, if there is a next line on the screen, line feed information indicating that a line feed has been performed is written. As described above, the operation result is stored in the time table, and after the editing of one piece of music is completed, the subcode information of the image data is generated from the data in the time table and is stocked in the MT 50 'for CD mastering.

FIG. 6 is a diagram showing an example of a lyrics screen on the CRT 9 during synchronous editing. In this example, the character string of the lyrics has two lines, a character string L1 on the first line and a character string L2 on the second line, and the current color change position is the fourth character “sake” of the character string L1.
At the position of the cursor C which overlaps with. The cursor C is a red vertical line, and the character string L1 on the first line is displayed.
Is orange at the beginning of the line from the cursor C and is white at the end of the line from the cursor C. The color of the character string L2 on the second line is white from the beginning to the end of the line.
That is, when actually playing karaoke, the cursor is not displayed, but the part that has already been sung is orange,
The part to be sung will be displayed in white.

The screen shown is a screen output switch 12
This is a screen in which the color change is performed by operating the lever 11 by outputting the lyrics screen by the operation of. That is, when the lyrics screen is output by operating the screen output switch 12, the character strings L1 and L2 are both white, and the operation knob 11a of the lever 11 is moved to the end A by the end of the operation input for the screen before this. Or, because it has reached the position of end B,
First, a cursor C is displayed at the beginning of the line of the character string L1 (the left end of the character ""). Then, by moving the operation knob 11a of the lever 11 in accordance with the progress of the music, the cursor C moves to the end of the line following the character string L1, and the white characters are sequentially changed to orange characters.

Here, the maximum movement range of the cursor C in the horizontal direction of the screen is set to the maximum span (range from FIG. 6) that can be displayed by one line of the character string, and the operation knob 11a of the lever 11 is set. Movement range (end A and end B
Is set to correspond to the maximum movement range of the cursor C. Then, the CPU 10a 'moves the cursor C based on the position of the operation knob 11a of the lever 11.
Is controlled as follows.

For example, when the operation knob 11a is moved from the end A to the end B, the cursor C is moved to the character string L1 in FIG.
When the operating knob 11a is moved to the end B, the cursor C is moved to a position past the end of the line of the character string L1. At this time, the operation knob 1
When 1a reaches the end B, the cursor C is set to (the position of) the next line. When the operation knob 11a is moved from the end B to the end A, the cursor C is moved from the head of the character string L2 to the end of the line.

In the case where the beginning of the line is located after the position, that is, the character string L2, the operation knob 11a is still at the end (in this case, even if the cursor C is at the end of the line). Does not reach the end A), and the cursor C is stopped and displayed at the end of the line (position) even if the operation knob 11a is moved as it is. Then, the operation knob 11a
Is positioned at the end (end A), the cursor C is set at the position of the next line head (in this case, the line head of the next screen).

In order to obtain the position of the cursor C based on the position of the operation knob 11a as described above, the CPU 10a 'performs, for example, the following operation. First, using the flag α indicating the moving direction of the operation knob 11a, α = 0 when moving from the end A to the end B, and α = 1 when moving from the end B to the end A.
And The output voltage at the intermediate position of the lever 11 is X volts, the output voltage of the lever 11 when the operation knob 11a is at the end A is 0 volt, and the output voltage when the operation knob 11a is at the end B is Vmax. The horizontal coordinate of the position of the bolt is 0 (number of pixels), the horizontal coordinate of the position is Pmax (number of pixels), and the coordinate of the beginning of the character string is Y ₀ (from address information stored in advance as data). The horizontal coordinate Y of the cursor is calculated by the following equation (1) or (2).

[0030]

(Equation 1)

[0031]

(Equation 2)

When the calculation result of Y exceeds the coordinate value (maximum coordinate value) of a displayable pixel as shown in the position of FIG. 6, Y is regarded as the maximum coordinate value. From the above calculation, the position of the cursor C, that is, the color change position is obtained, and is converted into image data.

FIGS. 4 and 5 are flowcharts of the main part of the control program executed by the CPU 10a 'of the synchronous editing apparatus according to the embodiment. The operation at the time of synchronous editing will be described based on the flowchart. Prior to the synchronous editing operation, the lyrics image file and the illustration image file generated by the generation device of FIG. 7 are converted to MT5 as data of the lyrics image file and the illustration image file to be synchronously edited.
0 'and stored in the memory 10b'.
Further, the DAT 6 is loaded with a DAT tape on which a karaoke song is recorded, and the operation is started simultaneously with the audio reproduction by the DAT 6.

First, when the operation is started, in step S1, the time code information decoded by the time code decoding circuit 4 is read, and in step S2, it is determined whether or not the current time code has advanced by one frame of the display image. 1
If it has not advanced by one frame, the process returns to step S1, and if it has advanced by one frame, it proceeds to step S3. Step S
At 3, the output of the lever 11, that is, the position information is read,
In step S4, it is determined whether or not the position of the operation knob 11a on the lever 11 has changed from the previous time. If not, the process proceeds to step S13 in FIG. Perform the corresponding processing.

On the other hand, if the position of the operation knob 11a has changed from the previous time, in step S5 the position of the lyric image to be changed from the beginning of the line, that is, the color change lever from which the position where the cursor C is displayed is read. 11 is calculated from the output voltage of the memory 11 by the above-described operation.
The information of the color change position is temporarily stored in an area corresponding to the current frame of the time table b '.

Next, in step S7, the lyric image data is converted into font data composed of data obtained by changing the color of the pixel of the portion where the color is to be changed and the cursor C, and in step S8 the font data is converted into subcode information. After conversion and output to the subcode encoding circuit 5, step S9
Proceed to. By outputting the subcode information to the subcode encoding circuit 5 in this manner, the color-changed lyric image is displayed on the CRT 9 and the operation at the time of editing is confirmed.

Next, in step S9, it is determined whether or not the operation knob 11a has reached the end A or the end B based on the output of the lever 11, and the operation knob 11a has reached the end A or the end B. If not, the process returns to step S1, and if the end A or the end B has been reached, it is determined in step S10 whether or not there is a next line of lyrics on the screen of the current lyrics image. If there is no next line, the process returns to step S1. If there is another line, the flag α indicating the moving direction of the operation knob 11a is inverted in step S11, and the cursor C is set at the beginning of the next lyrics. That is, the data of the lyric image at the beginning of the line of the next lyric is converted into font data composed of data obtained by changing the color of the pixel at the cursor C, converted into subcode information, and output to the subcode encoding circuit 5. . Then, in step S12, the line feed information is stored in an area corresponding to the current frame of the time table in the memory 10b ',
It returns to step S1.

The process of FIG. 5 is a process when the position of the operation knob 11a on the lever 11 has not changed from the previous time. First, in step S13, the state of the screen output switch 12 of the synchronous editing console 1 is read. In S14, it is determined whether or not the screen output switch 12 has been pressed. If the screen output switch 12 has not been pressed, the process directly returns to step S1 in FIG. 4. If the screen output switch 12 has been pressed, it is determined in step S15 whether the next screen data has been prepared. If the next screen data is not prepared, the process returns to step S1.

If the next screen data is prepared, the next screen data is converted into font data in step S16, and the font data is converted into subcode information in step S17 and output to the subcode encoding circuit 5, In step S18, the output screen information is temporarily stored in an area corresponding to the current frame of the time table in the memory 10b ', and the process proceeds to step S19. Then, step S19
Then, it is determined whether or not the output screen is a lyrics image screen. If the output screen is not a lyrics image screen, the process returns to step S1 in FIG.
To set the cursor C at the beginning of the next lyrics,
It returns to step S1 of FIG.

By operating the operation knob 11a of the lever 11 by the above processing, the cursor C moves and the lyrics image is sequentially changed in color and displayed, and the operation knob 11a is moved to the end A or the end B. Then, if there is a line of the next lyrics, the cursor C is moved to the beginning of the line and the color change is displayed therefrom. The time table of the memory 10b 'stores color change position information, that is, color change timing information, and output screen information, that is, screen output timing information, corresponding to the steps of each frame of the display image. You.

When the synchronous editing of one song is completed as described above, subcode information is generated based on the time table stored in the memory 10b ', and the subcode information is recorded on the data tape by the MT 50'. I do. And
When the subcode information of the number of songs for one title is recorded, the subcode information for one title is supplied to the mastering device using the cassette tape, and the digital karaoke software cut on a CD is completed.

As described above, in the synchronous editing console 1, just by reciprocating the operation knob 11a of the lever 11, it is possible to input the color change timing by tracing the lyric image for each one-way direction. Each time the vehicle reaches the end B for one way, it is sufficient to wait at that position until the next line starts, so that the operation becomes extremely easy. Of course, no matter how many lines of character strings exist in one lyric image, it can be input in a reciprocating motion.

In this embodiment, since the next screen can be output by operating the screen output switch 12, both the operation of the lever 11 and the operation of the screen output switch 12 can be performed with one hand, and continuous operation can be performed throughout one song. Can be input to the file, thereby improving the efficiency of editing work.

In the embodiment described above, the moving direction of the operation knob 11a of the lever 11 in the synchronous editing console 1 is arranged to be in the front-back direction, but may be in the left-right direction. In addition,
Since the character strings in different lines are traced from the beginning of the line (left side) to the end of the line (right side) in the forward path and the return path of the operation knob, it is easier to perform the operation by arranging the operation knob in the front-rear direction.

In the above embodiment, since the cursor C is displayed at the color change position, the monitor (CRT 9)
It is not necessary to display a lyric image whose color has been changed as in actual digital karaoke software. When displaying the color-changed lyric image on the monitor screen, the cursor C is not displayed. In other words, it is only necessary that the color change position can be displayed in real time by any index regardless of the presence or absence of the cursor and the shape of the cursor.

Further, in the above embodiment, the present invention
The case where the present invention is applied to editing of karaoke by graphics has been described. However, it is needless to say that the present invention is not limited to the recording medium and format of the digital karaoke software, but can be applied to video karaoke, video disk karaoke, and the like. .

[0047]

As described above, according to the present invention, the display means displays the character string of the lyrics together with the index indicating the position changing in the direction of the character string, and the user can manually reciprocate in a certain section. In conjunction with the movement of the operation knob, the index is moved from the beginning of the character string to the end of the character string, and the display position of the index is stored as the color change position of the lyrics in association with the time information. Since the index is set to the display position of the beginning of the next character string every time it reaches the end of a certain section, the end position of the operation knob always corresponds to the beginning of the line of the lyrics character string, so reciprocating movement The character string can be traced from the beginning of the line for each one-way
It becomes easy to input the data of the color change timing of the lyrics according to the music.
