[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a karaoke apparatus that displays an image in synchronization with a karaoke performance.
[0002]
[Prior art]
Currently, many karaoke apparatuses are connected to a monitor, and in synchronization with the karaoke performance, video and lyrics suitable for the song are displayed on the monitor. Such a karaoke apparatus is provided with a changer incorporating a plurality of optical disks storing video data of a moving image, and selects and reproduces an image corresponding to a song to be played from the optical disk.
[0003]
[Problems to be solved by the invention]
However, the karaoke apparatus provided with the above changer has a drawback that the price is high, and the apparatus becomes large and heavy, so that it is not suitable for a portable karaoke apparatus. In addition, the number of mechanisms for exchanging / reproducing optical disks increases, so that there is a disadvantage that failures increase.
[0004]
In addition, currently portable karaoke devices have been commercialized to store still images on a hard disk and display them on a monitor during karaoke performance, but the video is extremely monotonous and can boost karaoke performance. There was a drawback that could not be done.
[0005]
An object of this invention is to provide the karaoke apparatus which can implement | achieve the image display rich in change even if it is a still image.
[0006]
[Means for Solving the Problems]
The invention of claim 1 of this application is a karaoke that plays karaoke songs based on music data. Playing means, Image storage means for storing a plurality of background still image data and a plurality of foreground still image data, and a time series of image specifying data for simultaneously specifying one background still image data and one or a plurality of foreground still image data Image sequence data storage means for storing a plurality of image sequence data arranged in the image data, and image designation data is read from the image sequence data in parallel with the performance of the karaoke song, and background still image data designated by the image designation data And image synthesis means for synthesizing the foreground still image data to create display still image data and supplying it to the monitor In the karaoke apparatus, the image synthesizing unit is configured to provide one or both of the background still image data and the foreground still image data so that the background still image data and the foreground still image data to be synthesized have the same color tone. Correction means for correcting the color tone, the correction means comprising an average value for each of the three elements (hue, saturation, brightness) of the color of the background still image data, and the color of the foreground still image data Is a means for determining one or both of the background still image data and the foreground still image data by calculating a correction value for the three elements of the color based on the average value of each of the three elements. It is characterized by that.
[0009]
Claims in this application 2 According to the invention, an average value of three elements of each background still image data and each foreground still image data is stored in the image storage means in advance, and the correction means uses the average value to calculate the correction value. It is characterized by being indexed.
[0011]
this In the invention, background still image data and foreground still image data are stored, and these are combined to create display still image data. As a result, various types of still image data for display can be created with a small number of still image data, and a variety of display can be performed with a small storage capacity. Furthermore, since the still image data is sequentially switched by switching the display based on the sequence data, the karaoke song can be excited.
[0012]
Also this According to the present invention, when the color tone of the background still image data to be synthesized and the foreground still image data are greatly different from each other, one or both of the color tones are corrected before being synthesized and brought close to each other. Thus, even when completely different background still image data and foreground still image data are combined, the foreground does not float from the background.
[0013]
Claim 2 In the invention, since the average values of the three elements of the above colors are stored in each of the background still image data and the foreground still image data, when calculating the correction value, these are obtained from the still image data body of the bitmap. Since it is not necessary to determine this, work becomes very efficient.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram of a karaoke apparatus according to an embodiment of the present invention. This karaoke apparatus is a small karaoke apparatus in which the entire apparatus including the monitor 26 and the amplifier / speaker 22 is housed on a wagon movable by a caster. This karaoke device drives the sound source device 18 and the like by the music data selected by the karaoke singer to perform karaoke performance, and displays video and lyrics on the monitor 26. In this karaoke apparatus, the video is not a moving image but a display still image composed of a plurality of still images is switched and displayed. Still image data includes background still image data and foreground still image data, each of which stores a plurality of data. Display still image data is created by combining foreground still image data on one background still image data. The display still image data is switched in accordance with the progress of the music so that an effect close to that of a moving image can be produced. Further, in order to prevent an unbalance between the color tones (hue, saturation, brightness) of the foreground still image data and the background still image data as the background, it is possible to correct the two tones closer.
[0016]
In this karaoke apparatus, the CPU 10 that controls the operation of the entire apparatus is connected to a ROM 11, RAM 12, hard disk storage device (HDD) 17, remote control receiver 13, display panel 14, panel switch 15, sound source device 18, audio, via a bus. A data processing unit 19, an effect DSP 20, a character display unit 23, and a display control unit 25 are connected.
[0017]
The ROM 11 stores an activation program necessary for activating this apparatus. System programs, application programs, and the like that control the operation of the apparatus are stored in the HDD 17, and are read into the RAM 12 by the above-described activation program when the apparatus is turned on. In addition to the program storage area, the RAM 12 is provided with an execution data storage area for reading music data for performing karaoke performance. Further, the HDD 17 has a storage capacity of about 700 to 800 MB, and as shown in FIG. 2, in addition to the program storage area 53, the music data file 50 for storing music data for 3000 to 4000 songs and the music data are matched. A BGP script file 51, a still image file 52, and the like that store a sequence of still images to be combined and displayed are provided.
[0018]
The remote control receiving unit 13 receives an infrared signal sent from the remote control 31 and restores the data. The remote controller 31 includes a command switch such as a music selection switch, a numeric keypad switch, and the like. When a user operates these switches, the remote controller 31 transmits an infrared signal modulated with a code corresponding to the operation. The display panel 14 is provided on the front face of the karaoke apparatus, and displays the currently playing song code, the number of reserved songs, and the like. The panel switch 15 is provided in the front operation unit of the karaoke apparatus, and includes a song code input switch, a key change switch, and the like.
[0019]
The tone generator 18 forms a tone signal based on the tone track data of the music data. The music data is read by the CPU 10 during karaoke performance. The tone track is composed of a plurality of tracks as shown in FIG. 2B, and the tone generator 18 simultaneously forms a plurality of part tone signals based on this data. The audio data processing unit 19 forms an audio signal having a specified length and a specified pitch based on the audio data included in the music data. The audio data is obtained by storing a signal waveform that is difficult to be generated electronically by the sound source device 18 such as a back chorus as ADPCM data as it is. The musical tone signal formed by the tone generator 18 and the voice signal formed by the voice data processing unit 19 are karaoke performance sounds, which are input to the effect DSP 20. The effect DSP 20 gives effects such as reverb and echo to the karaoke performance sound. The karaoke performance sound to which the effect is given is converted into an analog signal by the D / A converter 21 and then output to the amplifier / speaker 22. The amplifier / speaker 22 amplifies the input karaoke performance sound and the singing voice signal input from the microphone 27, and gives an effect such as echo to the singing voice signal and then emits the sound from the speaker.
[0020]
The character display unit 23 generates a character pattern such as a song title and lyrics based on the character data read from the song data (see FIG. 2) during the karaoke performance. Further, during the karaoke performance, the CPU 10 reads out and synthesizes predetermined background still image data and foreground still image data from the HDD 17 and inputs them to the display control unit 25 as display still image data. The character pattern and display still image data are combined by the display control unit 25 and displayed on the monitor 26. The still image data composition function will be described in detail later.
[0021]
2 to 4 are diagrams showing the contents stored in the HDD 17. In FIG. 2, the music data file 50 has an area of about 400 MB, and music data for 3000 to 4000 music is stored. Each piece of music data has a header as shown in FIG. 5B, and a music number and a genre code are written in this header. In a BGP (Back Ground Picture) script file 51, a plurality of song-corresponding BGP script data and a plurality of genre-corresponding BGP script data are stored. The BGP script data has the configuration shown in FIG. 3, and describes a procedure for synthesizing and displaying the background still image Bn and the foreground still image Fn. The song number is written in the header portion is the song-corresponding BGP script data, and the genre code is written in the header portion is the genre-compatible BGP script data. The song-corresponding BGP script data is read when the song data of the song number is played, and a still image is displayed on the monitor 26 in this procedure. In addition, as for the genre-corresponding BGP script data, when there is no tune-corresponding BGP script data corresponding to the music data (song number) to be played, data corresponding to the genre of the music is read. That is, the song-corresponding script data is not stored corresponding to all the song data, and this genre-corresponding BGP script data is used when existing song data such as an old song is played. The image data file 52 has an area of about 260 MB and stores a plurality of the above-described background still image data and foreground still image data. The number of stored still image data is about 2000 to 3000.
[0022]
FIG. 2B is a diagram showing the configuration of the music data. The music data is composed of a header, a musical sound track, a lyrics track, an audio track, an effect control track, and an audio data section. The header is a portion in which various data relating to the music data is written, and in addition to the music number and genre code, data such as a music title, a release date, and a performance time (length) of the music are written.
[0023]
Each track from the musical tone track to the effect control track is composed of a plurality of event data and sequence data including duration data Δt indicating a time interval between the event data. The CPU 31 reads the data of all tracks in parallel based on the sequence program during karaoke performance. The sequence program is a program that counts Δt with a predetermined tempo clock, reads the event data that follows when Δt is counted up, and outputs the event data to a predetermined processing unit.
[0024]
The musical sound track is formed with various parts such as a melody track and a rhythm track. The lyrics track is a track that stores sequence data for displaying lyrics on the monitor 26. In the data description of the lyrics track, one line of lyrics is normally handled as one lyrics display data. The lyric display data includes lyric character data (character code and display coordinates of the character) of one line, display time (usually around 30 seconds) of the lyric, and wipe sequence data. Wipe sequence data is sequence data for changing the display color of the lyrics as the song progresses. The timing for changing the display color (time after the lyrics are displayed) and the change position (coordinates) ) Is data sequentially recorded over the length of one line.
[0025]
The audio track is a sequence track that designates the generation timing of audio data n (n = 1, 2, 3,...) Stored in the audio data portion. The voice data section stores voices such as back chorus and harmony singing that are difficult to synthesize with the sound source device 18. In the audio track, audio designation data and duration data Δt for designating the timing at which the audio designation data is read out, that is, the timing at which the audio data is output to the audio data processing unit 19 to form an audio signal are written. The voice designation data includes a voice data number, pitch data, and volume data. The audio data number is an identification number n of each audio data recorded in the audio data part. The pitch data and volume data are data for instructing the pitch and volume of audio data to be formed. In other words, back choruses such as “Ah” and “Wawa Wawa” without words can be used many times by changing the pitch and volume, so one data is stored at the basic pitch and volume. The pitch and volume are shifted based on the above and used repeatedly. The audio data processing unit 19 sets the output level based on the volume data, and sets the pitch of the audio signal by changing the reading interval of the audio data based on the pitch data. On the effect control track, DSP control data for controlling the effect DSP 20 is written. The effect DSP 20 imparts reverberation-type effects such as reverb to the signals input from the sound source device 18 and the audio data processing unit 19. The DSP control data is composed of data for specifying the kind of effect and its variation data.
[0026]
FIG. 3 is a diagram showing a configuration example of BGP script data, and FIG. 4 is a diagram showing a configuration of still image data. FIG. 5 is a diagram showing an example of switching display still image data based on the BGP script data.
[0027]
In FIG. 3A, BGP script data includes a header and a plurality of script lines. The corresponding music number or the corresponding genre code is written in the header. The data to which the corresponding music number is written is the music corresponding BGP script data, and the data to which the corresponding genre code is written is the genre compatible BGGP script data. It should be noted that both the corresponding song number and the corresponding genre code may be written so that the song-corresponding BGP script data and the genre-corresponding BGP script data are also used. A script line is described every time display still image data is switched. The description content of the script line is as follows.
[0028]
tn: switching time: indicated by elapsed time from start of performance
En: Effect type: Screen switching mode
Specify the type of (effect)
xe, ye: center point of the effect: specify the start point or end point of the switching mode
Tn: Time required for effect: Designates the time from the start to the end of video switching.
Bn: background still image number: designating still image data for background
Fn: Foreground still image number: Designate foreground still image data
xf, yf: foreground display coordinates: display coordinates of upper left corner of foreground still image data are designated Ha, Sa, La: color tone correction value: correction value for matching the color tone of background image data and foreground image data
It is.
[0029]
tn, is described in units of 1/30 second, which is one frame of the NTSC system. In addition, as a switching mode of the screen,
Cut-in: Switch instantaneously
Dissolve: Randomly switch the section that finely divides the screen.
Wipe: Switch left / right or up / down
Door: Switch from the specified line (vertical line including the center point) to the specified line from the left or right or left and right
Shutter: Switch from the designated line (horizontal line including the center point) to the designated line from the top and bottom or from the top and bottom
Cross: Switching from the center point to the outer periphery or from the outer periphery to the center point
PinP: Switching from the center point to the outer periphery or from the outer periphery to the center point
Line: Switch from multiple specified lines up and down
Mosaic: Switching from multiple center points to the outer circumference
Each is assigned an En value. Of these, cut-in is the default, and parameters of En, xe, yes, and Tn can be omitted when the screen is switched by cut-in.
[0030]
The foreground display coordinates xf and yf are values in the range of 0 to 384 and 0 to 240, respectively. The tone correction values Ha, Sa, and La are correction values for the hue, saturation, and brightness of each pixel (bit) of the foreground still image data. The hue correction value Ha takes a value of −180 to 180. The correction is performed so that the hue of each pixel is a hue obtained by rotating the hue on the color circulation (color wheel) clockwise by an angle corresponding to a specified value.
[0031]
The saturation correction value Sa takes a value of −100 to 100. Saturation correction is performed by equally dividing the current saturation value (0 to 100) and saturation 100 by 100 and assigning a value of 1 to 100 to each pixel. A value between −1 and −100 is assigned by dividing 100 between the value and saturation zero. Then, the saturation value corresponding to the value indicated by the saturation correction value is corrected. When Sa = -100, a gray scale image is obtained. The brightness correction value La takes a value of −100 to 100. The lightness correction is performed by equally dividing the lightness value (0 to 100) currently designated for each pixel and the lightness 100 by 100 and assigning a value of 1 to 100, and the lightness value currently designated and the lightness 0 are assigned. And −1 to −100 are assigned. And it correct | amends to the brightness value corresponding to the value which the said brightness correction value shows. When La = 100, the screen is white. When La = -100, the screen is black. These parameters are omitted when tone correction is not performed. If these parameters are all 0, a correction value is calculated based on the average value of the hues (hue, saturation, brightness) of the specified background still image data and foreground still image data. Based on this, the foreground still image data is corrected.
[0032]
FIG. 4 shows an example of background still image data and foreground still image data stored in the image data file 52. In FIG. 5A, background still image data is composed of a background still image number Bn, a genre code, an average HSL, and a data body. The background still image number Bn is a number for identifying the image data, and the image data is designated by this number in the BGP script. The genre code indicates in which genre this image data is used, and is the same type as the genre code written in the header of the music data. Note that by assigning a predetermined range of background still image numbers Bn to each genre, it is also possible to determine the genre of the background still image data based on the background still image number Bn. The average HSL is an average value of the hue H, saturation S, and brightness L of all the pixels of the data body. By calculating and storing this in advance, it is possible to increase the efficiency of color tone correction work during image composition. The data body is 384 × 240 dot 16-bit image data. Each image data is composed of a landscape or city image suitable for the genre code.
[0033]
On the other hand, the foreground still image data includes a foreground still image number Fn, an average HSL, and a data body. The foreground still image number Fn is a number for identifying this image data in the same manner as the background still image number Bn, and the image data is designated by this number in the BGP script. The average HSL is an average value of the hue H, saturation S, and brightness L of all the pixels of the data body. The data body can be set to an arbitrary size of 384 × 240 dots or less, and is 16-bit or 8-bit image data. The foreground still image data is defined by a rectangle of the number of vertical bits × the number of horizontal bits, but an image having a substantially arbitrary shape can be formed by making the bits in the image data transparent.
[0034]
FIG. 5 is a diagram showing a switching procedure of display still image data created by synthesizing background still image data and foreground still image data according to the BGP script data example shown in FIG. It is assumed that the first still image is displayed superimposed on a title still image displaying a song title or the like, or merged after the title still image.
[0035]
First, in the first line of the script line, the background still image data with the number B1 is designated, and the foreground still image data with the number F1 is designated. Since the tone correction value is omitted, display still image data is created by combining the coordinates of x1 and y1 without correction. Since the effect parameter is omitted, the display switching is cut-in, and this display still image data is immediately displayed at the time t1.
[0036]
Next, in the second line of the script line, the background still image data with the number B1 is designated, and the foreground still image data with the number F2 is designated. Since -30, -50, and 40 are written as tone correction values, the foreground still image data is corrected according to the correction values. The correction method will be described in detail later. Display still image data is generated by combining the corrected foreground still image data with the coordinates of x2 and y2. Since E1 is written as an effect parameter, still image data is switched over time T2 to time T1 with an effect corresponding to this. Since the background still image data is the same (B1), only the foreground seems to be switched from F1 to F2.
[0037]
In the third line of the script line, the background still image data with the number B2 is designated, and the foreground still image data with the number F3 is designated. Since the tone correction value is omitted, display still image data is created by combining the coordinates of x3 and y3 without correction. Since the effect parameter is omitted, the display switching is cut-in, and the still image data for display is displayed immediately at the time t3.
[0038]
Next, in the fourth line of the script line, the background still image data with the number B2 is designated, and the foreground still image data with the number F1 is designated. 0, 0, and 0 are written as color tone correction values. Since this tone correction value is an instruction to calculate and correct the correction value in real time, the correction value is calculated based on the average value of the tone of the background still image data and the foreground still image data, This corrects the foreground still image data. Display still image data is generated by combining the corrected foreground still image data with the coordinates of x4 and y4. Since E2 is written as an effect parameter, still image data is switched over time T4 to time T3 with an effect corresponding to this.
[0039]
The same background still image data and foreground still image data can be used to animate the foreground object as if the foreground still image data is shifted gradually. .
[0040]
6 to 9 are flowcharts showing the image display operation of the karaoke apparatus. FIG. 6 shows the operation at the start of karaoke. When a song is selected by the user, the song data is read from the HDD 17 to the RAM 12 to start karaoke performance (s1). The header of the read music data is checked to read the music number and genre code (s2). BGP script data corresponding to the music number is searched from the BGP script file (s3). If song-corresponding BGP script data corresponding to this song exists (s4), the song-corresponding BGP script data is read (s5), and all still image data used in this BGP script exists in the image data file. It is checked whether or not (s6). If all the still image data exists (s7), the process proceeds to the BGP synthesizing operation of FIGS.
[0041]
On the other hand, if the song-corresponding BGP script data does not exist (s4), the process proceeds to s9 to search for the genre-corresponding BGP script data corresponding to the genre of this song (s9). If some of the still image data used in the BGP script does not exist (s7), the read song-corresponding BGP script data is discarded (s8), and the genre-corresponding BGP corresponding to the genre of this tune The script data is searched (s9). Since the genre-corresponding BGP script data is normally stored corresponding to all genres, the genre-corresponding BGP script data corresponding to the genre of this song is searched (s10). The searched genre-corresponding BGP script data is read (s11), and it is checked whether or not all still image data used in the BGP script exists in the image data file (s12). When all the still image data exists (s13), the process proceeds to the BGP synthesizing operation of FIGS.
[0042]
On the other hand, if there is no part of the still image data used in the genre-compatible BGP script data (s13), this genre-compatible BGP script data cannot be used, and this data is discarded ( s14) The background still image data corresponding to the genre of this song is selected from the image data file (s15). It is assumed that a plurality of selections are selected according to the performance time of the karaoke song. Then, the process proceeds to the background image display operation of FIG.
[0043]
7 and 8 are flowcharts showing the BGP combining operation. When the performance of the karaoke song starts, first, a title still image is displayed (s20). While the title still image is displayed, the script pointer i is set to 1 (s21), and the i-th script line is read from the BGP script data (s22). The timing data ti described in the script line is set in the timer (s23), and while the ti is measured, the designated background still image data and foreground still image data are read (s24). , S25). Next, it is determined whether or not the correction parameter is included in the script line (s26). If the correction parameter is not included, the process proceeds to s31 as it is. If correction parameters are included, it is determined whether all the parameters are 0 (s27). If not all 0, the process proceeds to s29 to correct the foreground still image data with this value. On the other hand, when all the values are 0, it is an instruction that the correction value should be calculated based on the HSL average value of the background still image data and the HSL average value of the foreground still image data. A correction value is calculated based on the average value of the HSL included in the headers of the background still image data and the foreground still image data (s28). This correction value calculation operation is as follows. First, the HSL average values Hb, Sb, Lb of the background still image data and the HSL average values Hf, Sf, Lf of the foreground still image data are read from the header of the still image data, and these average values h, s, l are obtained. calculate. Then, the difference (h−Hf, s−Sf, l−Lf) between the average value h, s, l of the both and the HSL average value Hf, Sf, Lf of the foreground still image data is set as the correction value Ha, Sa, Let it be La. In s29, the color tone of the foreground still image is corrected based on the correction value. This correction operation is as follows. First, since the foreground still image data is stored as RGB data, it is converted into HSL data. Since the hue correction value Ha takes a value of −180 to +180, the hue value H of each pixel of the foreground still image data is rotated by this angle to obtain a corrected hue value. Since the saturation correction value Sa takes a value of −100 to +100, when the saturation correction value Sa is negative, the saturation between the 0 and the current saturation value S is equally divided into 100 for each pixel. When the saturation value is the corrected saturation value, and the saturation correction value Sa is positive, the saturation correction is performed by dividing the current saturation values S and 100 into 100 equal parts for each pixel. Let the value of the ratio Sa be the corrected saturation value. Since the lightness correction value La takes a value of −100 to +100, when the lightness correction value La is negative, the lightness correction value La is divided into 100 equal parts between 0 and the current lightness value L for each pixel. When the brightness value is corrected and the brightness correction value La is positive, the current brightness value L and 100 are equally divided into 100 for each pixel to correct the brightness correction value La ratio value. Value. After this, the process proceeds to s31.
[0044]
In s31, the foreground still image data is synthesized on the background still image data on the basis of the foreground coordinate values xf and yf. Thus, display still image data is created. After that, the process waits until ti expires (s32). When ti expires, it is determined whether or not the effect parameter En is described in the script line (s33). If there is no effect parameter En, it is switched immediately by cut-in (s34). If there is an effect parameter En, the effect (switching mode) indicated by that parameter is set (s35), and the time of Ti is multiplied. The screen is switched from the previous display still image data to the current display still image data (s36). In this script line, it is determined whether or not the BGP script data is terminated (s37). If not terminated, 1 is added to i (s38), and the process returns to s22. If it is completed, the currently displayed still image is deleted after waiting for the end of the music (s39), and the process ends. The above operation may be performed when ti describes the time from the previous script execution in each script line, and when ti describes the time from the start of the song, the value set in the timer Ti-t _(i-1) And it is sufficient.
[0045]
FIG. 9 is a flowchart showing a still image display operation. This operation is executed when there is no BGP script data corresponding to the music data to be played. First, a title still image is displayed (s41). After the title still image is displayed, i is set to 1 (s42), and the i-th data among the selected background still image data is read and displayed (s43). While the background still image data is being displayed, a predetermined time (about 30 seconds) elapses (s45) or until the music ends (s46). When a certain time has passed. 1 is added to i (s45), and the process returns to s43 to read / display the next background still image. When the music is finished, the display on the monitor 26 is erased (s47), and the operation is finished.
[0046]
In this embodiment, one foreground still image data is combined with the background still image data. However, a plurality of foreground still image data may be combined. The color tone correction may be performed not only on the foreground still image data but also on the background still image data. In the above operation, the HSL average values Hb, Sb, and Lb of the background still image data and the HSL average values Hf, Sf, and Lf of the foreground still image data are read from the header of the still image data, and the average values thereof are obtained. However, if Hb, Sb, Lb and Hf, Sf, Lf are not stored in advance, the hue value H, saturation value S, and brightness value L of each pixel of the still image data are all averaged in real time. The average value of the levers may be obtained.
[0047]
【The invention's effect】
this According to the invention, the background still image data and the foreground still image data are combined to create display still image data, which are displayed while being sequentially switched. However, it is possible to provide a video rich in changes close to a moving image as a monitor display of a karaoke apparatus.
[0048]
Also this According to the invention, when the background still image data and the foreground still image data are combined, by correcting so that the color tone is the same, it is possible to eliminate the uncomfortable feeling that occurs when combining different image data, Natural images can be provided.
[0049]
Claim 2 According to the invention, in addition to the background still image data and foreground still image data, the average values of these three elements of hue, saturation, and brightness are stored in advance, so these are calculated by calculation. Therefore, the correction process can be performed in a very short time as compared with the case where the correction is performed, and the processing time can be shortened.
