Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device and method for displaying a character string on the screen of a display device, and more particularly to a device suitable for a karaoke device and a lyrics display device.

[0002]

2. Description of the Related Art In a karaoke device as one of music reproducing devices, when reproducing a music, generally, a music title, a singer, a composer,
The lyrics of the song are displayed in sequence along with the information of the lyricist,
For the convenience of the user. Video disc or CD-
In a karaoke device using a package medium such as G (CD graphics), lyrics (character strings) recorded as analog images or image data are displayed.
Further, as a supplementary means for the user, that is, the karaoke singer to match the lyrics to the melody and sing at the correct timing, the display color of the displayed lyrics is sequentially changed along the character string indicating the lyrics. It is done like this.

In this case, when the karaoke data is created, the color change of the lyrics is caused by the person in charge who manually operates the manual lever of the display color changing encoder according to the performance while listening to music while listening to the music. Is changed to match the timing of the original lyrics. That is, a character string whose color is sequentially changed by the display color change information (color change data) of the characters of the lyrics obtained by such a manual operation is recorded as it is as image information and is reproduced, so that the karaoke is used. Even when the lyrics are displayed, the display color of the lyrics is changed as in the recording.

In the conventional general karaoke apparatus, there is no particular problem because the display color of the characters of the lyrics is changed when the data is recorded by such a system and reproduced. However, in recent years, a system called "communications karaoke" has been developed and is already in use, and the circumstances have changed. In online karaoke, SMF (standard MID) is sent from the host (station) to the terminal installed at the karaoke performance reproduction site.
The performance data and the lyrics data are transmitted as digital signals by a MIDI signal of the (I file) format.
In order to change the color of the lyrics in such a communication karaoke device, it is necessary to also send color change data for changing the color of the lyrics in accordance with the speed of the song.

FIG. 10 is a block diagram showing a terminal side of such a communication karaoke apparatus, that is, a reproducing apparatus. The contents of each data constituting the music database in this figure are as follows. Performance data: MIDI data that controls the sound source. For example, note-on, pitch bend, program change, etc. Lyrics data: Data about lyrics displayed on the display. A character code of the characters that make up the lyrics, a character display position, a character / outline color, a typeface, a tag that specifies the range of ruby, etc. Color change data: In the lyrics display, the part where the song is finished and the part where the song is going to be performed are displayed in different colors, but the data indicating the position of the boundary. The color change data is passed to the color change control unit and the actual processing is performed. There are two methods of describing the color change data: (a) describe when the color change position changes by one pixel (b) describe at an appropriate time interval (for example, every 1/60 seconds). The above (a) faithfully describes the change in pixel color. For example, if the number of pixels constituting the screen in the horizontal direction is 640 pixels, one line of lyrics (one column or one
A message is generated 640 times instead of changing the color of the column character string to one line). However, the display is
Since the screen cannot be rewritten for less than / 60 seconds, it is meaningless to describe the change in color change data at a shorter interval than that. Therefore, the scanning interval of the display (for example, 1 /
There is a method to describe the current color change position every 60 seconds. This is the method of (b). In the case of this method, if it takes, for example, 3 seconds to change the color of one line of lyrics, a message is generated 180 times.

Further, in the conventional communication karaoke apparatus, since characters such as lyrics are transmitted as code information, the display mode is limited, and the character strings are simply displayed and the character strings are sequentially displayed in accordance with the performance. The content of was only updated.

[0007]

In the above-mentioned conventional communication karaoke apparatus, a considerable amount of data has to be transmitted as character string color change data, resulting in an increase in communication cost and an increase in communication time. Furthermore, when compared with a conventional system for reproducing an optical disc on which a video signal is recorded, which is a general karaoke apparatus, the mode of character display in conventional communication karaoke is limited to a simple one. Fade in that becomes clearer over time, fade out that gradually fades, and further, for example, when singing duet, the color change of the lyrics of the male and female displayed in two lines alternates according to the singer's alternate charge part. It was not possible to realize various expressions such as changing the color of two lines at the same time. Therefore, the present invention provides a character string display color change signal generation device capable of reducing the amount of color change data of a character string displayed in an image, and an accurate display color change of a character string with such color change information having a small amount of data.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a preferred embodiment of a character string display color change signal generation device of the present invention. In the character string display color change signal generation device of FIG. 1, the sequencer 22 reads out from the storage device 24 in which the performance data and the lyrics data are stored in advance and is reproduced and displayed. That is, the audio data output from the sequencer 22 is given to the sound source section 30, an analog signal is generated, amplified by an internal amplifier, and given to the speaker 32. Further, the lyrics data from the sequencer 22 is given to the lyrics display section 26, and the corresponding character is selected from the internal character generator and displayed on the display 28 as a character string. In this state, the operator changes the color and operates the input device 10 while monitoring the screen and sound. The color change input device 10 is a device having a movable lever, for example, and generates a signal for changing the color change position on the screen according to the moving position of the lever. That is, the position information of the lever is given to the color change control unit 14 as a digital signal by the A / D converter 12. When the sequencer 22 reproduces a performance, a reference time is required. Therefore, the timer 20 inputs time data at regular intervals to the sequencer 22 to perform at a predetermined tempo.
The output of the timer 20 and the position information from the color change input device 10 supplied via the A / D converter 12 are processed by the data collection unit 16 to collect the color change position information at regular intervals, and the color change primary Generate data. This method can generate the data in (b) above. The above configuration is the same as the conventional one. In the present invention, the color change primary data is post-processed by the calculator 18 to obtain the acceleration data as the color change secondary data.

FIG. 2 is a flowchart showing a procedure for obtaining acceleration data (color change secondary data) from color change primary data. That is, the arithmetic unit 18 has a CPU, a memory and the like, and this CPU operates according to the flow of FIG. 2 to obtain acceleration data. The color change primary data is data describing color change position information s for each time Δt at equal intervals. First, the difference data of s (t) is calculated from this data (step S1). This becomes velocity data v (t). Next, the v data is smoothed (step S2) and the tendency of the change in speed is obtained. Further, the time at which the v data can be approximated to a straight line, that is, the time interval (for example, 1/60 seconds) that can be regarded as the uniform acceleration motion is calculated (step S3). For this section, the acceleration of this section is calculated from the speed v (ti-1) of the start point of the section calculated from the acceleration one section before and s (t) of the end point of the section (step S4).
~ S6). After this processing is performed for all sections (steps S6 to S8), the difference from the original s data is calculated for all t values (step S9), and if a certain allowable value is exceeded (step S10). Returning to the section calculation section, the section of the section necessary for improving the resolution is subdivided (step S1).
1) is performed and the above processing is repeated.

FIG. 3 is a graph showing the timing of color change of "a star falls on a cold night" as an example of a character string indicating lyrics, and graph A showing position information with respect to time and speed data obtained therefrom. Graph B showing
Further, a graph C showing the acceleration data obtained from the speed data is also shown side by side. Generally, in a part where the change in speed is discontinuous, the human perception has a dynamic sense of “bounce, bounce, kick”. It is difficult to sing unless the color change position of the lyrics moves smoothly. Therefore, by describing the color change with acceleration instead of speed, it is possible to describe color change data that is easy to sing and has a small amount of data.

The acceleration data and the like obtained by the above method are given to the karaoke player together with the lyrics data. M
In the case of a communication karaoke device using an IDI signal, performance information and character information by a MIDI signal are transmitted as a code from the host (station) to the terminal according to the SMF data format. Further, image information and the like can be added as needed. As the color change data, acceleration data, its change time data, and initial speed data are sent as a control change code of a SMF MIDI event or a system exclusive event. As is well known, each of the above events is paired with a delta time (Δt), and the timing control during reproduction is accurately performed. The initial velocity data is, for example, the first character of the one-line character string arranged in the horizontal direction (“cold” in the example of FIG. 3).
Is velocity data at a reference position such as a start position such as a left end portion of the. Velocity data, if you know this initial velocity,
After that, since it can be obtained one after another from the acceleration data and the change time data thereof, it is sufficient to send the velocity data only for the first reference position. The configuration of the terminal has the same block configuration as that shown in FIG. 10, but the color change control unit 62 is configured to generate speed data and control the color change of the character string using the initial speed, the acceleration, and the change time thereof. It is different from the conventional terminal in that it is performed.

Next, a first embodiment of a character string display device and a character string display method capable of controlling a display mode of a character string for each row of the present invention will be described. FIG. 4 is a block diagram of the first embodiment of the character string display device of the present invention. The character string display device shown in FIG. 4 shows a part of the terminal side of the communication karaoke device, and this terminal is connected to a host (station) not shown via a high-speed digital line such as ISDN or a general public line. The performance information in the form of a MIDI signal is sent from the host as needed, as in the previous example. In addition to performance information, character information and its control information, image information, etc. are transmitted.

FIG. 5 is a diagram showing the data format of the control information of the character information, and FIG. 6 is a diagram showing how the display mode of the character string displayed on the screen is controlled and changes over time. In the block diagram of FIG. 4, the music database 40 is composed of a large-capacity memory such as a hard disk device, and stores lyrics data for thousands of songs, its color change data, and fade data.
Also, if necessary, new music data can be added from the host via a communication line (not shown). The sequencer 42 sends the lyrics data, the color change data, and the fade data to the lyrics display section 46, the color change control section 62, and the fade data generation section 48, respectively, based on the time information from the timer 44.

The character generator 50 sends a character font to the lyrics display section 46. The line block buffer 52 temporarily stores a plurality of lines of character data for each line, and the output data for each line is the line block brightness control unit 5.
6, where the line-by-line control signal from the line block intensity register 54 controls the intensity of the characters for each line. The color change control unit 62 changes the display color of the character string, and its output signal is given to the lyrics display unit 46. The fade data generation unit 48 receives the control data in the format shown in FIG. 5, creates a control signal for each row to perform control for each row, and sends the control signal to the row block brightness register 54. The display row block selection circuit 58 receives the output signal of the row block brightness control section 56, determines the display position on the screen and creates a video signal, and this video signal is sent to the display 60, either alone or. Characters are displayed by being superimposed on an image formed by a signal from a video signal circuit (not shown).

FIG. 6 shows that the character string is displayed in three lines as shown in the image P1, and the first line (line block 1) at the top of the lines is faded out. That is, when the fade-out is started in the image P2, the characters of the row block 1 are gradually faded as shown in the image P3, and then the row block 1 is completely erased as shown in the image P4. The one shown in FIG. 6 is merely an example. As shown below, one of modes 1 to 4 is designated by 2 bits, and the speed of luminance change is set by 3 bits as shown in the data format of FIG. It is possible to specify any of up to 8 lines by using the 8-bit stage mask. Such data is S as in the case described above.
It can be sent as a control change code of MF MIDI event or as a system exclusive event.

Although the method of changing the color of the character string is not specified in this embodiment, the acceleration data shown above can be used or the same method as the conventional method can be used. Next, the above four modes will be described. Mode 1: Switch page Switch to the page defined most recently in this message. If there is one currently displayed, it will be cut out (disappearing momentarily). Rows with a row block mask of 1 are immediately displayed (cut in), and those with 0 are not displayed. The color change data of each line is the initial value. Mode 2: Page restart The page currently displayed is initialized. It is the same as the mode 1 except that the pages are not switched. In this mode, the same character data is displayed again, and the color change position becomes the start position. Mode 3: Fade in The specified line on the currently displayed page fades in.
Nothing happens when it is already displayed. A line block mask is used to specify the line. The row where 1 stands is faded in. Color change data does not change. The fade-in speed is specified in 8 steps. Mode 4: Fade out The specified line on the currently displayed page fades out. If it has already disappeared, nothing happens. A line block mask is used to specify the line. The row where 1 stands is faded in. Color change data does not change. The fade-in speed is specified in 8 steps.

As described above, in the embodiment shown in FIGS.
Since the fade process can be independently performed for each line, it is possible to perform the fade without synchronizing with the lyrics, such as displaying the song name of the medley, in addition to displaying the lyrics.

Next, a second embodiment of the character string display device and the character string display method capable of controlling the display mode of the character string for each line of the present invention will be described. As shown in the block diagram of FIG. 7, this embodiment has many parts in common with the first embodiment of FIG. 4, and the difference is that the color change control unit 64 simultaneously outputs the color change data for each row. This is the point of outputting to the block buffer 52. With this configuration, it is possible to perform a variety of displays such as performing color changes on a plurality of lines at the same time or changing a color on a part of one line and then changing a part of another line.
As the color change data, acceleration data can be used, or data created by the same method as the conventional method can be used. In this embodiment as well, the brightness of characters can be changed using the fade data as in the first embodiment.

FIG. 8 is a diagram showing a format of color change data in the second embodiment of the character string display device and the character string display method. FIG. 9 is a diagram showing a display example on the screen.
In the data format of FIG. 8, either the velocity or the acceleration is designated by the first first bit. Next, specify one of the character strings on the 1st to 8th lines with 3 bits,
The last 8 bits indicate either speed data or acceleration data.

In the display example of FIG. 9, the images P5 to P7 show the state of color change which changes with the passage of time, and the portion where the display color has been changed is surrounded by a frame for easy understanding. For example, in the case of a duet composed by a man and a woman, the display colors of the character strings in a plurality of lines are simultaneously displayed in a manner as shown in FIG. 9 in order to accurately guide the alternate singing and singing together. Alternatively, it can be changed in various ways such as alternately.

In order to realize the display example shown in FIG. 9 by using the initial velocity and the subsequent acceleration data, for example, the description as shown in the figure is made as the event information of the MIDI signal.

Δt0 color change line 1 speed v1 Δt1 color change line 1 acceleration-α1 Δt2 color change line 2 speed v2 Δt3 color change line 2 acceleration-α2 Δt4 color change line 1 acceleration α3

That is, each time (delta time) Δt0
At Δt4, a line is designated, a velocity or acceleration is designated, and the data (velocity or acceleration) is sent. As described above, the speed data need only be sent at the initial speed at the beginning position of each line, and after that, the color change can be reproduced only by the time information and the acceleration.

[0035]

As described above, according to the character string display color change signal generation device of the present invention and the character string display device and the character string display method using the character string display color change signal generated thereby, the time On the other hand, the color change information can be accurately expressed and reproduced with a considerably small amount of data as compared with the conventional method of transmitting the position information or the speed information which changes every moment. Therefore, if applied to the online karaoke device, the communication time can be shortened and the communication fee can be reduced. In addition, a storage device such as a hard disk,
Even when karaoke data is stored in a storage medium such as an optical disk, the amount of data to be stored can be small, effective use of the memory and medium, and reduction in access time can be achieved. Further, according to the character string display device and the character string display method capable of controlling the display mode for each row of the present invention, the display of various modes such as fade-in and fade-out of the character string can be realized even in the communication karaoke device, and the video signal It is possible to reproduce the same expression form as the conventional various character strings obtained by reproducing. In particular, since the fade process for each line can be performed independently of other lines, for example, when displaying the song name of a medley, an independent character string that is displayed without synchronizing with the lyrics display is displayed. Fade processing can be performed. Further, by performing the color change control independently for each line, it is possible to perform various color change controls such as changing the display colors of the character strings in a plurality of lines partially alternately or simultaneously.
