[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a music playback apparatus having a function of displaying an opening screen for introducing the contents of a song such as the song name when the song is played.
[0002]
[Prior art and problems to be solved by the invention]
  2. Description of the Related Art Conventionally, a music playback device having a function of displaying an opening screen that introduces the content of a song such as the song name when playing the song is known, and a karaoke device is a typical example. The karaoke apparatus stores music data in a storage means such as a hard disk. The song data is stored as one file for each song, and is composed of, for example, a song name, genre information, opening image data, opening image display time, MIDI data, subtitle data, and the like.
[0003]
  As basic operation in this karaoke device,
  1: Standby state
  2: Song number input by the operation panel (song selection)
  3: Music performance and singing,
The operations 2 and 3 are repeated according to the user's request, and when there is no user request, the operation is 1.
[0004]
  FIG. 8 illustrates details of the transition of contents (screen transition) displayed on the monitor in accordance with the basic operation. In FIG. 8 (A), the karaoke apparatus is in a standby state, and as a part of screen use in the standby state, for example, a latest music announcement display called a new music guide is performed. Here, when the music selection operation is performed by the user, the screen transitions to the screen mode shown in FIG. 8B, and the input song number and the song name corresponding to the song number are confirmed and displayed. Since the music number input is performed by a several-digit number key input and a music selection key, the display of the music number reception screen shown in FIG. 8B continues until the music selection operation by the user is completed.
[0005]
  When the music selection operation is completed, the screen transitions to the screen mode of FIG. 8C, and the opening screen is displayed simultaneously with the performance of the selected music. The opening screen announces the start of the performance of the music, presents information such as the name of the music, the name of the singer, the composer, etc., and displays a design drawing or a jacket photo created exclusively for the music. This opening screen is displayed using the opening image data D3 in the music data shown in FIG. 2, and the substance of the opening image data D3 is still image data.
[0006]
  The opening screen is erased after a predetermined time according to the opening image display time D4 in the music data shown in FIG. Then, a transition is made to the screen mode of FIG. 8D, and a performance screen that is the main subject of the karaoke performance starts. On the performance screen, a background image that matches the karaoke song and a superimposed caption are displayed, and the content proceeds in synchronization with the song performance. The time required for playing the music varies depending on the target music, but when the performance ends, the screen transitions to the standby screen in FIG. 8A, and thereafter this operation is repeated.
[0007]
  As described above, since the opening screen merely displays the opening image data D3 that is still image data, it naturally becomes a screen display that does not move, and is an expression for presenting information such as a song name, singer name, and composer. It will be poor.
[0008]
  Of course, it is possible to configure the opening screen using moving image data instead of still image data, but when moving image data is included in the music data of each song, the amount of data is considerably large because it is moving image data. turn into. In a situation where the number of songs that can be played by one karaoke device is enormous, such as tens of thousands, if the song data for each song becomes large, the total data of the song data to be stored in the entire karaoke device The amount will be enormous.
[0009]
  In addition, the opening screen is displayed by switching from a standby screen (song number reception screen (B) in the case of FIG. 8) showing predetermined information displayed before the opening screen. However, the person who sees the impression that the switching to the opening screen is too sudden will have. Similarly, after the opening screen is displayed, the background video associated with the karaoke performance will be displayed. In particular, on the still image opening screen, the impression that the transition to the background video screen associated with the subsequent karaoke performance is too sudden is seen. People have it.
[0010]
  In addition, it is not interesting to display only the requested song name and song number using the operation panel switch at the time of the request, so there are known techniques to display this with various animations and entertain the user. (For example, refer to Patent Document 1). However, this is a response at the time of request, and an operation panel is provided with an LCD matrix display, for example, and animation is displayed on the display. This is related to the karaoke performance itself such as when the opening screen is displayed on the monitor. Is not a coping.
[0011]
  Therefore, an object is to realize a more effective opening screen display while using still image data.
[0012]

[0013]
[Means for Solving the Problems and Effects of the Invention]
  In the music reproducing apparatus according to claim 1 made to solve the above-described problem, the storage means stores still image data for the opening screen. The still image data for the opening screen is prepared for each song and is used for displaying an opening screen that introduces the content of the song, such as a song name. Then, when the performance of the selected music starts, the control means displays the opening screen for a predetermined time using the still image data for the opening screen read from the storage means. At least one of the appearance effect process and the erase effect process is executed.
[0014]
  Effect processing at the time of appearance: This is executed when the display of the opening screen is started, and the still image data for the opening screen is processed so that the contents of the opening screen are gradually and clearly visible.
  Effect processing at the time of erasure: This is executed when the display of the opening screen is finished, and processing is performed on the still image data for the opening screen so that the contents of the opening screen are gradually seen indefinitely.
[0015]
  In this way, the image data for the opening screen is prepared for each music piece. However, in the present invention, since it is still image data, the data capacity of the storage means is smaller than when moving image data is used. Also good.
  Nevertheless, the appearance effect process executed by the control means processes the still image data so that the contents of the opening screen are gradually and clearly visible, and the effect process at the time of deletion is the contents of the opening screen gradually. The still image data is processed so as to be seen indefinitely. Since the display contents are varied in this way, the appeal effect to the viewer who sees the opening screen is improved and the entertainment is also improved.
[0016]
  Further, the display time of the opening screen is not always constant. Therefore, the display time information of the opening screen is stored corresponding to the still image data, and control is performed so that the opening screen fits within the display time based on the display time information when executing the effect processing at the time of appearance or the effect processing at the time of deletion. To do.
[0017]
  Assuming that the ratio of transition screens by the effect process at the time of appearance and the effect process at the time of erasure and the ratio of the complete display screen not by those effect processes with respect to the entire display time of the opening screen are determined respectively, Take control. That is, when executing the effect process at the time of appearance or the effect process at the time of erasure, the display time based on the display time information is set to the display time of each screen based on the ratio of the transition screen to the entire display time of the opening screen and the ratio of the complete display screen. The transition screen and the complete display screen are displayed according to the determined time.
[0018]
On the other hand, there are cases where it is desired to change the ratio of the transition screen to the entire display time of the opening screen and the ratio of the complete display screen per se. In that case, a device as shown in claim 2 may be devised. That is, the ratio of the transition screen to the entire display time of the opening screen and the ratio of the complete display screen itself are stored corresponding to each piece of music, and are stored when executing the effect process at the time of appearance and the effect process at the time of deletion. Each ratio is read to determine the display time of each screen, and the transition screen and the complete display screen are displayed according to the determined time.
[0019]
In addition, the ratio of the transition screen by the effect process at the time of appearance and the effect process at the time of erasing with respect to the entire display time of the opening screen may be expressed by a non-dimensional value such as ○%, ○%, for example, As shown in claim 3, it may be expressed as the display time of each screen relative to the standard display time of the opening screen. For example, assuming that the standard display time is 8 seconds, the transition screen by the effect process at the time of appearance is 2 seconds, the complete display time is 4 seconds, the transition screen by the effect process at the time of deletion is 2 seconds, etc. It may also be a value that is indicated. If the display time of the opening screen is 8 seconds of the standard time, the stored display time of each screen may be used as it is in the actual display control, or the opening screen display time is shorter than the standard time. If it is 6 seconds, for example, the display time obtained by multiplying the stored display time of each screen by three-quarters may be used for display control.
[0020]
In addition, as shown in claim 4, if the performance image related to the performance of the music is displayed when the display of the opening screen is completed, the contents of the opening screen are gradually visually recognized by the effect processing at the time of erasure. In this way, the performance image is switched, so that the uncomfortable feeling caused by the sudden switching of the screen can be alleviated. Also, before switching to the opening screen, nothing is displayed, or a standby screen for performing a new music guide or a song number reception screen is often displayed. Therefore, even when the screen is switched from the screen without any display or the standby screen to the opening screen, if the contents of the opening screen are gradually and clearly seen by the effect processing at the time of appearance, the screen switching is too sudden. Can alleviate the sense of discomfort.
[0021]
  When executing the effect process at the time of appearance or the effect process at the time of erasure, as shown in claim 5, it is conceivable that any one of a plurality of process patterns can be selected and executed. In this way, the effect content at the time of switching the screen does not become one pattern, and it is effective in terms of appealing to the viewer of the opening screen and improving entertainment. In selecting this processing pattern, for example, it is conceivable to select in order or randomly. However, depending on the processing pattern, there may be a thing that matches the opening screen more or less. Therefore, as shown in claim 6, when storing the genre information corresponding to the still image data for the opening screen in the storage means and executing the effect process at the time of appearance and the effect process at the time of deletion, the genre information The processing pattern may be selected based on the above.
[0022]
  In addition, there is a so-called medley song in which a plurality of songs are partially incorporated in one song. In the case of this medley song, it is desirable to display an opening screen that introduces the contents of the song, such as the song name, when playing the plurality of songs. At present, for example, the title of a song is introduced as a part of subtitle telop data indicating lyrics, but the content is very inconspicuous. Therefore, as in the present invention, if the opening screen of each constituent song in the medley song can be varied, it is more effective in terms of appealing to the viewer of the opening screen and improving entertainment. .
[0023]
  Such a music playback device is, for example, a claim8It can be realized as a karaoke device as shown in FIG. In other words, the music playback apparatus is a karaoke song and a performance image is a background image. Of course, a device in which the music is not a karaoke music but a normal music music may be used.
[0024]
  Claims 1 to8When the control means in the music playback device described in any of the above is realized by a computer, it can be provided as a program executed by the computer, for example. Such programs are, ExampleFor example, it is recorded on a computer-readable recording medium such as a flexible disk, magneto-optical disk, CD-ROM, hard disk, ROM, RAM, etc., and loaded into a computer for execution as necessary, or loaded through a network for execution. By doing so, the function as a scoring means can be realized.

DETAILED DESCRIPTION OF THE INVENTION
  Embodiments to which the present invention is applied will be described below with reference to the drawings. Needless to say, the embodiments of the present invention are not limited to the following examples, and can take various forms as long as they belong to the technical scope of the present invention.
[0026]
  FIG. 1 is a block diagram illustrating a configuration of a karaoke apparatus 1 according to the present embodiment. The karaoke apparatus 1 according to the present embodiment includes an operation panel 10 for performing a song reservation operation, a CPU 14 for controlling the karaoke apparatus 1 as a whole, a memory for storing system programs, setting data necessary for various settings, and the like. 15. A MIDI sound source unit 18 that performs performance reproduction based on MIDI data (music data), a sound processing unit 19 that performs sound processing appropriately by mixing the reproduced sound from the MIDI sound source unit 18 and the singing voice of the user (singer), etc. , An amplifier 20 that amplifies an electrical signal related to the audio information output from the audio processing unit 19, a speaker 22 that inputs an electrical signal from the amplifier 20 and plays an accompaniment and a user (singer) singing voice, etc. A microphone (hereinafter simply referred to as a microphone) 23 for inputting the singing voice of the performer (singer) to the sound processing unit 19, music data for karaoke ( 2 reference) and image information stores other various data hard disk 13, image processing unit 24 for imaging the image information and the like, and a monitor 26 for displaying the background image and lyric or the like as image information. Among these, the operation panel 10, the hard disk 13, the memory 15, the MIDI sound source unit 18, the audio processing unit 19, and the video processing unit 24 are connected to the CPU 14.
[0027]
  The karaoke apparatus 1 of this embodiment is called a so-called communication karaoke, and although not shown, it can be connected to a host computer via a communication network. And the karaoke apparatus 1 can acquire the music data (refer FIG. 2) regarding karaoke from the host computer connected via this communication network.
[0028]
  Here, the operation panel 10 is operated by the user, and can select an arbitrary song, adjust the pitch of the performance sound, adjust the volume balance between the performance and the song, and perform various adjustments such as echo, volume, and tone. It has switches and buttons for performing.
  The hard disk 13 stores music data, content data such as image information, and the like. When a song is selected via the operation unit of the operation panel 10, the CPU 14 calls the song data from the hard disk 13 and outputs it in synchronization with the video processing unit 24 and the MIDI sound source unit 18. . The composition of music data stored in the hard disk 13 is shown in FIG. The music data corresponds to a music number as identification information, and is stored as one file for each music. As shown in FIG. 2, the music data is composed of a music title D1, genre information D2, opening image data D3, opening image display time D4, MIDI data / subtitle data D5, and the like. The song name D1 indicates the title of the song by text data, and the genre information D2 is information (data) in which attributes of songs such as enka, pops, rock, nursery rhymes, and animation are encoded. The opening image data D3 is one piece of still image data, and the opening image display time D4 is a value indicating the time for which the opening image should be displayed in seconds. The MIDI data / caption data D5 includes sound generation data accompanying reproduction by a MIDI sound source and subtitle text data displayed in synchronization therewith.
[0029]
  The MIDI data output from the CPU 14 is converted into an analog performance sound signal by the MIDI sound source unit 18, and then sent to the sound processing unit 19. Mixed at a rate. The mixed singing sound signal and performance sound signal are sent to the amplifier 20 to be electrically amplified. Furthermore, it is output from the amplifier 20 to the speaker 22 and output as sound and performance sound from the speaker 22 to the outside.
[0030]
  On the other hand, the video processing unit 24 reproduces an image based on image information read from the hard disk 13 under the control of the CPU 14. Thereby, the lyrics data output by the CPU 14 is synthesized with the video data in the video processing unit 24, and the lyrics telop is displayed on the screen of the monitor 26 together with the background video.
[0031]
  Due to such a configuration, the user can sing using the microphone 23 in accordance with the karaoke performance flowing from the speaker 22 while referring to the lyrics telop displayed on the monitor 26.
  This karaoke apparatus 1 has basic operations as follows:
  1: Standby state
  2: Song number input by operation panel 10 (song selection)
  3: Music performance and singing,
The operations 2 and 3 are repeated according to the user's request, and when there is no user request, the operation is 1.
[0032]
  The karaoke apparatus 1 of the present embodiment has a characteristic content in the control relating to the display of the opening screen during this basic operation. Therefore, the contents of display control in the prior art will be compared and the point will be described in detail.
  [Display control of the opening screen in the prior art]
  The screen transition by the conventional display control has been described with reference to FIG. 8 in the description of the prior art, but will be simply repeated.
[0033]
  In FIG. 8 (A), the karaoke apparatus is in a standby state, and as a part of screen use in the standby state, for example, a latest music announcement display called a new music guide is performed. Here, when the music selection operation is performed by the user, a transition is made to the song number reception screen shown in FIG. 8B, and the input song number and the song name corresponding to the song number are confirmed and displayed. When the music selection operation is completed, the screen transitions to the screen mode of FIG. 8C, and the opening screen is displayed simultaneously with the performance of the selected music. The opening screen is erased after a predetermined time according to the opening image display time D4 in the music data shown in FIG. Then, the screen changes to the performance screen shown in FIG. 8D, and the performance screen that is the main subject of the karaoke performance starts. On the performance screen, a background image that matches the karaoke song and a subtitle superimposed on it are displayed, and the content proceeds in synchronization with the song performance. When the performance is finished, the state transitions to the standby state shown in FIG. 8A, and this operation is repeated thereafter.
[0034]
  FIG. 9 shows these operations as a time chart focusing on the time axis direction. As can be seen from the time chart of FIG. 9, it is “occurrence of key operation” that determines the timing for transition from the standby screen to the song number reception screen, and the timing for transition from the song number reception screen to the opening screen is determined. Is “completion of key operation”, and it can be read that it is the data of the opening image display time that determines the timing of transition from the opening screen to the performance screen.
[0035]
  In the display control of the opening screen according to such a conventional method, as described above, the opening image data D3 that is still image data is simply displayed. , The expressive power to present information such as composers will be poor.
[0036]
  Therefore, in this embodiment, the following display control is performed in order to realize a more effective opening screen display while using the same still image data in the opening screen display.
  [Display control of opening screen in this embodiment]
  In the display control according to the present embodiment, the following appearance effect process and erase effect process are executed when the opening screen is displayed.
[0037]
  Effect processing at the time of appearance: This is executed when the display of the opening screen is started, and the still image data for the opening screen is processed so that the contents of the opening screen are gradually and clearly visible.
  Effect processing at the time of erasure: This is executed when the display of the opening screen is finished, and processing is performed on the still image data for the opening screen so that the contents of the opening screen are gradually seen indefinitely.
[0038]
  FIG. 3 shows screen transitions displayed on the monitor 26 by the display control of this embodiment, and FIG. 4 shows a time chart focusing on the time axis direction.
  3 (C), (D), and (E) correspond to the opening screen in this embodiment. Compared to the screen transition according to the conventional method shown in FIG. 8, FIG. Is different from the display effect (effect process at the time of appearance) shown in FIG. 3 and the deletion effect (effect process at the time of deletion) shown in FIG. That is, in the state shown in FIG. 3D, the contents of the opening screen can be clearly seen, but in the state where the display effect shown in FIG. 3C is applied, the contents of the standby screen are gradually increased. While changing so that it may be visually perceived indefinitely, the content of the opening screen is gradually changed so as to be clearly visible. On the other hand, in the state where the erasing effect shown in FIG. 3E is applied, the contents of the opening screen change so as to be visually recognized gradually, and the contents of the performance screen are gradually visually recognized. Has changed. In this way, the opening screen is superimposed on the standby screen and the performance screen in the video processing unit 24, so that the standby screen shown in FIG. 3B suddenly changes to the clear opening screen shown in FIG. 3D. Instead of switching, an effective screen transition is made such that the opening screen appears gradually from the standby screen. Similarly, instead of suddenly switching from the clear opening screen shown in FIG. 3 (D) to the performance screen of FIG. 3 (E), an effective screen transition is made such that the opening screen gradually disappears and the performance screen appears. .
[0039]
  Further, the time chart in the case of the present embodiment shown in FIG. 4 is compared with the time chart in the case of the conventional method similarly shown in FIG. In the case of the present embodiment, as shown in FIG. 4, the display period of the opening screen is divided into three, and is divided into a display change period a, a complete display period b, and an erase change period c. . As can be seen from FIG. 4, the timing of transition from the standby screen (FIG. 3 (A)) to the song number reception screen (FIG. 3 (B)) is determined by “occurrence of key operation”. When the “ten key” on the operation panel 10 is operated for input, the timing for transition from the song number reception screen (FIG. 3B) to the opening screen is determined by “completion of key operation” That is, when the “tune selection key” or “execution key” on the operation panel 10 is operated, the music data is read from the hard disk 13 to the memory 15 and the performance is started in terms of internal processing. When Further, it is the data of the opening image display time D4 (see FIG. 2) that determines the timing of transition from the opening screen to the performance screen (FIG. 3F). When a song number is input during performance (when there is a reserved song), the transition to the opening screen is when the performance of the previous song is completed and the performance of the next song is started. These are the same as the conventional screen transition timing in FIG. 9, but in the case of the present embodiment, as shown in FIG. 4, the calculation timing 1 at which the display change period a is newly completed and the transition to the complete display period b is performed. In addition, two timing elements of calculation timing 2 that complete the complete display period B and change to the erasure change period C are added.
[0040]
  In this embodiment, the calculation timing 1 and the calculation timing 2 are automatically calculated based on the opening image display time D4 stored in the music data shown in FIG. A specific example of this calculation will be described in the following flowchart.
[0041]
  Note that some supplementary explanation will be given to the data of the opening image display time D4 stored in the music data of FIG. The reason why this data is necessary is that some karaoke songs require singing along with subtitles immediately after the performance starts, that is, a type with a short prelude, but for a while immediately after the performance starts. There is a type in which only accompaniment continues and then singing along subtitles begins, that is, a type with a long prelude, and an intermediate type. Since the length of the prelude differs depending on the music in this way, it is inconvenient if it is not possible to determine for each music how long the opening image is to be displayed. Moreover, if the opening image is displayed, there is an advantage that the song cannot be sung because it overlaps with the caption display.
[0042]
  In this embodiment, the above-described device has been devised in order to prevent such inconvenience and to provide an additional effect on the opening screen.
  Next, the overall operation of the karaoke apparatus according to the present invention in which an additional effect is added to the above-described opening screen will be described in detail with reference to the flowcharts of FIGS.
[0043]
  FIG. 5 is a main flow showing an overall processing sequence of the karaoke apparatus 1. When the operation of the karaoke apparatus 1 is started at the start of the sequence (F01), first, a new music guide process is executed (F02). The guidance of the latest music registered in is displayed. The screen of the monitor 26 in this case is as shown in FIG. The internal details of the new music guide process are not the main points of the present invention, and thus the description thereof is omitted.
[0044]
  In the new music guide process, as long as no key operation is performed (F03: NO), the process (new music guide process) is continued, but when a key on the operation panel 10 is operated to input a music number. (F04: YES), the new music guide process is terminated, and the process proceeds to the music number input process (F04).
[0045]
  In the song number input process (F04), the user waits for input of several digits and a song selection key indicating completion of input via the operation panel 10 and displays the song name corresponding to the completed song number on the screen. . The screen of the monitor 26 in this case is as shown in FIG. This music number input process (F04) is continued until the input operation is completed (F05: NO), and when the input is completed (F05: YES), the process proceeds to a music data reading process (F06).
[0046]
  In the music data reading process (F06), one of a plurality of registered music data in FIG. 2 is selected and read into the memory 5 using the value determined in the previous music number input process. Thereafter, in the karaoke performance process (F15), the reproduction performance by the MIDI sound source unit 18 is started for the read karaoke piece. In terms of internal processing, the starting point of the playback performance is the starting point of time measurement in the opening screen processing described below. The karaoke performance process (F15) is a multitask parallel process, and the reproduction performance by the MIDI sound source unit 18 continues to proceed regardless of the progress of the subsequent flow. Since this reproduction performance processing is not the main point of the present invention, description thereof is omitted.
[0047]
  Thereafter, when the process shifts to the change timing calculation process (F07), the opening image display time D4 in the music data of FIG. 2 is used, and three values necessary for the subsequent opening screen process, that is, the display change time t1, A complete display time t2 and an erase change time t3 are calculated. As this calculation method, for example, if “x seconds” is designated as the value of the opening image display time D4, this “x seconds” is 30% for the display change time t1, 50% for the complete display time t2, and the erasure change. A method of dividing a limited time value such as 20% at time t3 into three at a constant rate is conceivable. For example, if “x seconds” is 10 seconds, the display change time t1 is 3 seconds, the complete display time t2 is 5 seconds, and the erase change time t3 is 2 seconds. The calculation timings 1 and 2 in FIG. 4 are determined by these times.
[0048]
  When this change timing calculation process (F07) is completed, the process proceeds to an opening screen effect selection (F08) process as an opening screen effect selection means, and branches to any of the four types of opening screen processes prepared in steps F09 to F12. .
  Various algorithms for selecting one of the four types are conceivable. For example, the following method of matching the impression of the screen effect with the musical piece to be played is conceivable. That is, in the song data reading process (F06), if the genre information D2 of the song data is “enka”, the opening screen process (water surface) in step F11, which is considered to have a soft impression from the screen effect, or the opening screen in step F12 Select processing (fade). If the genre information D2 of the music data is “pops”, the opening screen process (mosaic) in step F09, in which the impression received from the screen effect is considered pleasant, is selected. If the genre information D2 of the music data is “lock”, the opening screen process (tape) in step F10, which is considered to have a hard impression from the screen effect, is selected. The contents of the processes in steps F09 to F12 will be described later.
[0049]
  When each opening screen process from step F09 to F12 is completed, the process proceeds to karaoke subtitle process (F13), and subtitle display synchronized with the karaoke performance process already in progress is performed in step F15, which is the end of the performance of the target music piece. Will be continued. Note that the karaoke subtitle processing in step F13 is not the main point of the present invention, and thus the description thereof is omitted. If there is no reserved song when the performance of the target song is completed (F14: NO), the sequence ends (F15), and the process returns to step F01. If there is a reserved song (F14: YES), the process returns to step F06 to perform song data reading processing for the next reserved song. In addition, after the performance of the target music is finished in this way, that is, the performance screen display of the music is finished, the music data reading process for the next reserved music is performed and the performance screen for the music is displayed. For example, it may be possible to display a list of reserved songs at that time. In FIG. 3B, in addition to the standby screen, a song number + music name is displayed on the screen. For example, a list of song numbers + music names reserved at that time is displayed. Of course, a standby screen may be displayed.
[0050]
  Next, the details of each opening screen process from steps F09 to F12 described above will be described.
  FIG. 6 is a flowchart showing the contents of the opening screen process (mosaic) in step F09, and FIG. 7 is a flowchart showing the contents of the opening screen process (tape) in step F10. Although the flowcharts of the opening screen (water surface) in step F11 and the opening screen processing (fade) in step F12 are omitted, these are positioned as subroutines called from the entire flow of FIG.
[0051]
  [About opening screen processing (mosaic)]
  As shown in FIG. 6, when the opening screen process (mosaic) corresponding to step F09 in FIG. 5 is started (G01), the display is a parameter for determining the change timing calculated in step F07 in FIG. The change time t1, the complete display time t2, and the erase change time t3 are delivered (G02).
[0052]
  Then, by the repetitive processing in subsequent steps G03 to G06, the downward direction of the up and down arrow indicated by G13 in FIG. 6, that is, the order of (a) → (b) → (c) → (d) → (e) Then, image processing is executed. As shown in FIG. 6, this change is filled with a uniform color and an image with high transparency is gradually reduced as the four sides constituting the mosaic gradually become smaller and the transparency becomes smaller. e), and finally returns to the original image. Therefore, at first, the standby screen can be seen through, but gradually becomes unclear, and finally the opening screen is displayed.
[0053]
  This change is realized by repeatedly executing Step G04 while decrementing the value α from 10 to 0 in the processing of Steps G03 to G06, for example. In step G05, the display change time t1 is set to 1/10. Therefore, the screen process is adjusted to be completed by spending a time equal to the display change time t1.
[0054]
  The process of step G04, which is the center of the mosaic process, can be realized by, for example, a process in which the entire screen is tiled with four sides of a certain size. Specifically, the screen effect as if the resolution of the original image is lowered is obtained by determining the color data of each of the four sides based on the average value of the color data in the vicinity of the coordinates corresponding to the original image. The content of the processing in step G04 is that the size of the four sides is the variable parameter α.
[0055]
  When the processes of steps G03 to G06 are completed, the process proceeds to step G07, and a wait is set for the complete display time t2.
  Next, by repetition processing in steps G08 to G11, this time, in the upward direction indicated by G13 in FIG. 6, that is, (e) → (d) → (c) → (b) → (a). In this order, image processing is executed. As shown in FIG. 6, this change is that the original image (see (e) in FIG. 6) is gradually filled with a uniform color as the four sides constituting the mosaic gradually increase, and the transparency increases. Finally, the entire screen changes to the screen after the transition (see (a) in FIG. 6), so that the performance screen can be gradually and clearly visible.
[0056]
  This change is realized by repeatedly executing the process of step G09 while incrementing the value α from 0 to 10 in the processes of steps G08 to G11. In step G10, since the wait is made for a time that is one-tenth of the erase change time t3, an adjustment is made so that the screen processing is completed by spending a time equal to the erase change time t3. Note that the processing content itself of step G09 is the same as the processing of step G04.
[0057]
  When the processing of steps G08 to G11 is completed in this way, the process proceeds to step G12, and the opening screen processing (mosaic) processing is completed by returning to the overall flow of FIG.
  This makes it possible to achieve a screen effect in which the opening image appears in the mosaic instead of the standby screen, disappears in the mosaic again, and the performance screen appears, and the change time can be adjusted according to the music. .
[0058]
  [About opening screen processing (tape)]
  As shown in FIG. 7, when the opening screen process (tape) corresponding to step F10 in FIG. 5 is started (H01), the display is a parameter for determining the change timing calculated in step F07 in FIG. The change time t1, the complete display time t2, and the erase change time t3 are delivered (H02).
[0059]
  Then, by the repetitive processing in subsequent steps H03 to H06, the downward direction of the vertical arrow indicated by H13 in FIG. 7, that is, the order of (a) → (b) → (c) → (d) → (e) Then, image processing is executed. As shown in FIG. 7, this change is what the original image (refer to (e) in FIG. 7) with low transparency (for example, 0%) is different from the image before transition with high transparency (for example, 100%). The tape is partially transferred in a tape-like form, and all the original images are finally displayed. Therefore, at first, the standby screen can be visually recognized over the entire surface, but a part of it gradually changes to the screen after the transition (as the standby screen) becomes unclear, and finally the opening screen is displayed over the entire surface. Become so.
[0060]
  This change is realized by repeatedly executing the process of step H04 while incrementing the value x from 0 to 400 every 10 steps in the processes of steps H03 to H06. In step H05, the display change time t1 is multiplied by 1/40. Therefore, a time equal to the display change time t1 is spent, and the screen processing is adjusted to be completed.
[0061]
  In the process of step H04, which is the center of the tape-like screen process, for example, if the number of horizontal pixels of the screen is 400, if the rectangular image is transferred in several times with the horizontal size x of the original image as a band, Good. Since the parameter x increases from 0 to 400 for a while due to the repetition of steps H03 to H06, as a result, a screen effect is obtained in which some tapes that have hidden the screen are gradually peeled off. be able to.
[0062]
  When the processing in steps H03 to H06 is completed, the process proceeds to step H07, and a wait is set for the complete display time t2.
  Next, by the iterative process in steps H08 to H11, in the future, the upward and downward arrows indicated by step H13 in FIG. 7 are moved upward, that is, (e) → (d) → (c) → (b) → (a The image processing is executed in the order of). As shown in FIG. 7, this change is caused by erasing the original image into several tapes, and erasing so that the erased portion gradually becomes larger. (See (a) in FIG. 7), so that the performance screen can be gradually and clearly visible.
[0063]
  This change is realized by repeatedly executing the processing of step H09 while incrementing the value x from 0 to 400 every 10 steps in the processing of steps H08 to H11. In step H10, since the wait is made for the time that is 40 times the erase change time t3, it is adjusted so that the screen processing is completed by spending a time equal to the erase change time t3. In the process of step H09, for example, if the number of horizontal pixels on the screen is 400, the band-shaped filling process may be performed in several times with the horizontal size x. Since the parameter x is increased from 0 to 400 for a while by the operation of the repetitive processing in steps H08 to H11, an effect that the screen is hidden by some tapes can be obtained as a result.
[0064]
  When the processing of steps H08 to H11 is completed in this way, the processing proceeds to step H12, and the processing of the opening screen processing (tape) is completed by returning to the overall flow of FIG.
  This makes it possible for the opening image to appear as if the tapes that were hiding it were peeled off, and then to be hidden under the tape again. Can be adjusted.
[0065]
  In addition, although detailed description about the opening screen process (water surface) corresponding to step F11 of FIG. 5 and the opening screen process (fade) corresponding to step f12 is omitted, only an outline will be described.
  For example, in the case of the opening screen process (water surface), a screen transition in which the original image is greatly undulated and gradually disappears from a state where it cannot be seen and the screen transition, and vice versa, can be considered. For example, a process can be considered in which each line on the horizontal axis constituting the image is shaken by a function such as a sine wave, and the coefficient becomes smaller.
[0066]
  In addition, in the case of opening screen processing (fade), the screen transition (fade-in) that the original image gradually appears clear by simply changing the brightness of the screen, or conversely the original image gradually The screen transition (fade-out) may be considered so as to become unclear. In this case, it is only necessary to change the brightness of the pixel.
[0067]
  Thus, according to the karaoke apparatus 1 of the present embodiment, the following effects can be obtained.
  (1) When displaying the opening screen, the display effect (effect processing at the time of appearance) that applies processing to the still image data for the opening screen so that the content of the opening screen is gradually and clearly visible, and the content of the opening screen are gradually An erasing effect (effect processing at the time of erasing) is executed for processing the still image data for the opening screen so that it can be clearly seen. The opening image data D2 used for this processing is prepared for each music piece, but since it is still image data, the data capacity of the hard disk 13 may be smaller than when moving image data is used. Nevertheless, the display effect processes the still image data so that the contents of the opening screen are gradually and clearly visible, and the erasure effect still image data so that the contents of the opening screen are visually recognized gradually. Since the display content rich in change is obtained by processing, the effect of appealing to the viewer who sees the opening screen is improved, and the entertainment is also improved.
[0068]
  In addition, switching between the screens before and after the opening screen (song number standby screen, performance screen) is not too sudden as in the prior art, and the uncomfortable feeling is alleviated.
  (2) In the case of the present embodiment, the display effect and the erasure effect for the opening screen can be selected and executed from among four types of processing patterns. However, it is effective in terms of appealing to viewers of the opening screen and improving entertainment.
[0069]
  For this selection, for example, based on genre information D2 in the music data shown in FIG. 2, a method of matching the impression of the screen effect with the music to be played can be considered. Depending on the processing pattern, there may be more matches to the opening screen, and conversely, there may be less matches, so this is more effective.
[0070]
  In this embodiment, four types of effects have been proposed. However, this is merely an example, and naturally, more types may be prepared and the selection pattern may be increased. Further, the contents of the effect are not limited to the above example, and various effects can be adopted.
[0071]
  (3) The display time of the opening screen is not always constant and may vary depending on the music. Therefore, since the opening image display time D4 is included in the music data shown in FIG. 2 and the display effect and the erasure effect are executed, the opening screen display is controlled within the opening image display time D4. It can cope with the difference in the display time of the opening screen.
[0072]
  In this embodiment, the hard disk 13 corresponds to “storage means” and the CPU 14 corresponds to “control means”.
  Although the embodiments have been described above, the present invention is not limited to the above embodiments and can be implemented in various modes. Some of them will be explained.
[0073]
  (1) In the above-described embodiment, the opening screen erase effect is obtained by reversing the processing progress of the display effect. However, the screen display effect and the screen erase effect do not necessarily have to be paired. A combination is also conceivable. For example, the display effect may be “mosaic” and the erasure effect may be “tape”.
[0074]
  (2) In the above embodiment, for example, if “x seconds” is designated as the value of the opening image display time D4, this “x seconds” is 30% for the display change time t1, 50% for the complete display time t2, A method has been described in which a limited time value such as 20% for the erase change time t3 is divided into three at a constant rate. Therefore, with this method, t1: t2: t3 = 3: 5: 2 is constant. However, there may be a case where it is preferable to change the ratio of these table times according to the music. If it corresponds to such a situation, the ratio of the display change time to the entire display time of the opening screen and the ratio of the erase change time itself are further stored in the music data shown in FIG. When executing the process or the effect process at the time of erasing, it is conceivable to read the stored ratios to determine the display time of each screen and to control the display of the opening screen according to the determined time.
[0075]
  In this case, for example, the display change time t1, the complete display time t2, and the erasure change time t3 may be set as non-dimensional values such as ○% and ○% of the total time, or the standard of the opening screen It may be expressed as the display time of each screen with respect to the display time. For example, assuming that the standard display time is 8 seconds, it may be a value that directly indicates the display time, such as t1 = 2 seconds, t2 = 4 seconds, t3 = 2 seconds. If the opening image display time D4 is 8 seconds of the standard time, the stored display time of each screen may be used as it is in actual display control, and the opening image display time D4 is greater than the standard time. If it is 6 seconds, for example, the display time obtained by multiplying the stored display time of each screen by three-quarters may be used for display control.
[0076]
  In the above embodiment, the opening screen display effect and the erasing effect are executed as a pair. However, for example, only the display effect can be executed or only the erasing effect can be executed. In consideration of application to such a case, as described above, a method of setting each of t1, t2, and t3 as a ratio to the total time or as the time itself is effective. For example, if only the display effect is executed and the erase effect is not executed, t3 = 0 may be set. Conversely, if only the erase effect is executed without executing the display effect, t1 = 0 may be set. Because.
[0077]
  (3) When selecting and executing any one of a plurality of processing patterns as the display effect and the erasing effect for the opening screen, for example, it may be possible to select them sequentially or randomly. If priority is given to increasing visual change, such a measure may be used.
[0078]
  (4) In the above embodiment, the song number is received in a standby state, and an explanation is given with an example of shifting to the performance immediately after the reception. However, in the karaoke apparatus 1, a plurality of song number receptions are reserved, It is possible to adopt a request-type configuration in which the start and end of the performance are repeated as long as the music number is accumulated in the reservation queue. Accordingly, in such a configuration, the opening screen display effect and the erasing effect are performed following the end of the performance of the immediately preceding music piece.
[0079]
  In addition, when the display effect and the deletion effect for the opening screen are selected and executed from among a plurality of processing patterns, matching is based on genre information in the above embodiment, but this is the pattern number stored in the song data. You may specify directly by.
[0080]
  (5) Although the said Example demonstrated the case where it implement | achieved as the karaoke apparatus 1, the apparatus in which a music is not a karaoke music but a normal music music may be sufficient.
  (6) In addition, whether it is a karaoke song or a normal music song, there is a so-called medley song in which a plurality of songs are partially incorporated in one song. In the case of this medley song, it is desirable to display an opening screen that introduces the contents of the song, such as the song name, when playing the plurality of songs. For example, in the current karaoke apparatus, the name of a song is introduced as a part of subtitle telop data indicating lyrics, for example, but the content is very inconspicuous. Therefore, if the above-mentioned display effects and erasure effects are performed on the opening screen of each constituent song in the medley song, and the contents can be varied, the appeal effect to the viewer of the opening screen and the improvement of entertainment It is more effective.
[0081]
  (7) The above embodiment has been described on the premise that the screen before transition and the screen after transition are subjected to the superimposing process at the time of screen transition. However, instead of preparing the screen before the transition and the screen after the transition in the memory of the video processing unit 24, only one drawing screen is prepared in the memory of the video processing unit 24. The same screen transition can be realized by changing a part (pixels) of the screen before transition to the screen state after transition within one screen.
