JP 2002-262179 A

  In a conventional video processing apparatus, for example, when switching the above scene data in synchronization with music, it is necessary to switch manually. Moreover, even if this switching is performed automatically, it is difficult to change the switching timing in accordance with the change in the music tempo. Furthermore, when switching scene data, the switching speed (tempo speed) is changed without using the original speed as a reference. Therefore, the relationship between the beat position of the music and the switching timing of the scene data may be slightly shifted due to the change in speed. Therefore, even when the original speed is restored, the scene data switching timing may not match the beat position.

  An object of the present invention is to provide a video processing device capable of always synchronizing the beat position of music played simultaneously with the video switching timing.

Conversion ratio setting means for setting a conversion ratio to be converted; second tempo setting means for converting the first switching tempo at the set conversion ratio to set a second switching tempo; and the pattern data The scene data is switched and reproduced according to the first or second switching tempo based on the switching order represented by And reproducing means, based on the scene data to be the reproduction, with respect to data that is the input, and a data processing means for performing data processing.

In the present embodiment, a plurality of setting operators 9 are arranged on the panel of the video processing device 1, and the user uses these setting operators 9 to select, set, and save scene data and arpeggio pattern data. Various settings and operations such as playback are performed.

  The trigger switch (timing adjustment button) 8 is a switch arranged on the panel of the video processing apparatus 1 as with the setting operator 7, and the user operates (presses) the trigger switch 8 to arpeggio pattern. Instructs the adjustment of the data reproduction timing.

  The setting operator 7 and the trigger switch 8 may be a soft switch or the like displayed on a display unit (display) 9 that is operated using another operator such as a mouse.

Combine (add) and send to output terminal OUT.

  The output terminal OUT is a video output terminal that can be connected to an external display device, and outputs a synthesized video signal (channel addition signal) sent from the video synthesis unit 12 to the outside.

The video signal input to the video processing apparatus 1 of the present embodiment may be any signal as long as it can be displayed on a display device such as a moving image, a still image, or text data. In addition to the video signal, for example, an audio signal or automatic performance data such as a MIDI signal can be input and processed.

Further, the communication interface 13 may have a function capable of being connected to a communication network 13 such as a LAN (local area network), the Internet, or a telephone line.

  FIG. 2 is a schematic plan view showing a part of the operator panel installed on the upper surface of the video processing apparatus 1 according to the present embodiment.

  The operator panel installed on the upper surface of the video processing apparatus 1 includes a setting operator 7 including at least a change time setting switch 71, a main tempo setting switch 72, a tempo tap 73, a sub tempo setting switch 74, a tempo selection switch 75, and the like. A trigger switch 8 and a beat position display device (LED) 9L are arranged. Although not shown, on the operation panel, in addition to the above-described operators, for example, the video composition unit 12, the input selection switch 14, the image quality control unit 15, the display control unit 16, and the level control unit 17 in FIG. In addition, an operator group for setting the on / off switch 18 and the output selection switch 19, a liquid crystal display device, and the like are arranged.

  The change time setting switch 71 is an operator that performs settings for switching scene data by cross-fading. For example, when the change time is set to “100%”, a crossfade with the next scene data starts one beat before the switching timing, and when it is “50%”, one beat and one beat at the switching timing. Start a crossfade from the middle point. When the setting is “0%”, the scene data is switched at the switching timing without performing the cross fade.

  The main tempo setting switch 72 is an operator for setting the playback tempo of the arpeggio pattern data. For example, when this operator is turned to the left, the playback tempo is slowed (the main tempo speed is reduced), and when it is turned to the right, the playback tempo is fastened (the main tempo speed is increased).

  The tempo tap 73 is an operator for adjusting the playback tempo of the arpeggio pattern data. The user can set the main tempo based on the average time interval between the taps by tapping (tapping) the tempo tap 73 a plurality of times (for example, four times).

  In addition to the main tempo setting switch 72 and the tempo tap 73 described above, the main tempo can be numerically input using, for example, a normal cursor switch, numeric keys, a keyboard, and the like. Also, for example, tempo clock (F8), performance position information (measure / beat / clock, elapsed clock from the beginning of the song, elapsed time from the beginning of the song, etc.) etc. are received from the external device via the communication I / F 13. It can also be used.

  A sub-tempo setting switch (tempo conversion ratio setting switch) 74 is a switch for setting a conversion ratio for converting the main tempo. As the conversion ratio, for example, the main tempo such as “0.125”, “0.25”, “0.5”, etc. is fractionated, that is, a value for generating a sub-tempo speed slower than the main tempo speed, Values for multiplying the main tempo such as “2”, “4”, “8”, etc., that is, for generating a sub-tempo speed faster than the main tempo speed are prepared. The conversion ratio can be set to any numerical value, but the value for multiplication is preferably an integer, and particularly preferably includes “4”. Moreover, it is preferable that the value for fractionation is the reciprocal of the value for the multiple.

  For example, when playing an arpeggio pattern that switches scene data for each measure in accordance with a music of 4 beats, if the subtempo converted at the conversion ratio “4” is adopted, the scene data is switched for each beat. However, the scene data switching timing is the beat position. Also, for example, when playing an arpeggio pattern that switches scene data for each beat in accordance with a 4-beat song, if a subtempo converted at a conversion ratio of “0.25” is used, the scene data is stored for each measure. However, the scene data switching timing is the beat position.

  Thus, by generating the sub-tempo by converting the main tempo with an integer and its reciprocal, the beat position and scene data switching timing can be matched even when the arpeggio pattern is reproduced using the sub-tempo.

  In the above example, a conversion factor of a multiple of 2 and its reciprocal number is prepared in order to match 2-beat and 4-time music, but a multiple of 3 and its reciprocal are required to match a 3-time music. A conversion ratio may be prepared. Further, various conversion ratios may be prepared to match other time signatures. Regardless of the time signature, even if the main tempo is generated by converting the main tempo based on the number of beats of one measure and its multiples and their reciprocals, and the arpeggio pattern is played back, Scene data switching timing and beat position can be matched.

  The tempo selection switch 75 is a switch for selecting a tempo to be adopted as a reproduction tempo of the arpeggio pattern data as one of a main tempo and a sub tempo.

  The beat position display device 9L is a light emitting diode that lights up at each beat position of the playback tempo of the set arpeggio pattern and visually informs the user of the beat position.

  FIG. 3 is a conceptual diagram for explaining the scene data SN and the arpeggio pattern data ARP in the present embodiment.

  The scene data SN records settings of the video composition unit 12, the input selection switch 14, the image quality control unit 15, the display control unit 16, the level control unit 17, the on / off switch 18 and the output selection switch 19 shown in FIG. For example, the above settings at the time of recording the scene data SN are recorded, and the recorded settings can be instantaneously restored by reproducing the recorded scene data SN. The scene data SN can be edited later as well as recording the above settings at the time of recording the scene data SN. Alternatively, preset scene data SN may be recorded in the recording unit 6 in advance.

  For example, in the scene data SN1 shown in the drawing, the size of four video images is set to a quarter of the display screen, and settings are arranged so as to be displayed side by side on the display screen. In the scene data SN2, settings for displaying the other two videos whose sizes are reduced so as to overlap the video displayed on the entire display screen are recorded. In the scene data SN3, settings are recorded so as to overlap the video displayed on the entire display screen so as to reduce the size and transmit the lower video. In the scene data SNn, an image reduced to about one-fourth the size of the display screen is displayed on the upper right of the display screen, and about half the size so as to cover the lower right quarter of the image. Settings that are displayed are recorded. The scene data SN1 to SNn include image quality settings for each video in addition to the display mode settings described above.

  The arpeggio pattern ARP is composed of a combination of scene data. For example, the arpeggio pattern ARP is sequence data in which a plurality of scene data SN1 to SNn are recorded together with their reproduction order and reproduction timing (switching timing) Ctim. That is, “scene data SN1” → “scene data SN2”... “Scene data SNn” is recorded. Note that the arpeggio pattern ARP may be recorded in the form of “scene data SN1” → “scene data SN1 + difference between the scene data SN2 and the scene data SN1”.

  For example, as shown in FIG. 3, the arpeggio pattern ARP designates scene data SN1 to be reproduced at the head, and thereafter designates switching to the scene data SN2 to start reproduction at the switching timing. At the switching timing, it is specified to start playback by switching to the scene data SN3, and then, at the switching timing from the scene data SNn-1 to the scene data SNn, it is specified to start playback by switching to the scene data SNn. .

  The switching timing can be specified by a relative time (seconds) from the start of reproduction of the arpeggio pattern ARP, or can be specified by combining the number of measures and the number of beats.

  FIG. 4 is a flowchart showing the main processing of this embodiment.

  In step SA1, main processing is started, and in step SA2, various flags, registers, buffers, etc. are initialized.

  In step SA3, it is determined whether or not a main tempo / subtempo selection operation has been performed. For example, it is determined whether or not the tempo selection switch 75 shown in FIG. 2 has been operated. When the main tempo / subtempo selection operation is performed, the process proceeds to step SA4 indicated by an arrow of YES, and when the selection operation is not performed, the process proceeds to step SA5 indicated by an arrow of NO.

  In step SA4, the adopted tempo in arpeggio pattern playback is switched based on the selection operation detected in step SA3. For example, the selected tempo (main tempo MT or sub tempo ST) is stored in the register SLT. Thereafter, the process proceeds to step SA11.

  In step SA5, it is determined whether or not a main tempo setting operation has been performed. When the main tempo setting operation is performed, for example, when the main tempo setting switch 72 or the tempo tap 73 of FIG. 2 is operated, the process proceeds to step SA6 indicated by an arrow of YES. The process proceeds to step SA8 indicated by an arrow.

  In step SA6, the tempo speed of the main tempo (main tempo speed) MTS is set according to the setting operation detected in step SA5. For example, the value of the tempo speed set here is recorded in the register MTS.

  In step SA7, the sub tempo speed STS is changed according to the setting of the main tempo speed MTS in step SA6. Here, since the main tempo speed MTS that is the reference of the sub tempo speed STS is changed in step SA6, the sub tempo speed is changed in accordance with the change. The change of the subtempo speed STS is performed by the same process as in step SA10 described later. Thereafter, the process proceeds to step SA11.

  In step SA8, it is determined whether or not a sub-tempo setting operation has been performed. When the sub tempo setting operation is performed, for example, when the sub tempo setting switch 74 of FIG. 2 is operated, the process proceeds to step SA9 indicated by an arrow of YES, and when not operated, the process proceeds to step SA11 indicated by an arrow of NO. move on.

  In step SA9, the tempo conversion ratio is determined in accordance with the subtempo setting operation detected in step SA8. The subn tempo setting switch 74 is, for example, a value for fractionating the main tempo such as “0.125”, “0.25”, “0.5”, etc., that is, a value for generating a subtempo speed slower than the main tempo speed, And “2”, “4”, “8”, the position information corresponding to any one of the values for multiplying the main tempo, that is, generating a sub-tempo speed faster than the main tempo speed, is output. A tempo conversion ratio (TCR) is determined based on the position information.

  In step SA10, the subtempo speed (STS) is obtained by multiplying the tempo speed (MTS) of the main tempo set in step SA6 or preset by the tempo conversion ratio (TCR) determined in step SA9. Calculate (STS = MTS × TCR) and set as sub-tempo. Thereafter, the process proceeds to step SA11.

  In step SA11, it is determined whether or not the current adopted tempo (SLT) is the main tempo (MT) (SLT = MT). If the adopted tempo selected in step SA3 is the main tempo, the process proceeds to step SA12 indicated by a YES arrow, and if it is a sub tempo, the process proceeds to step SA13 indicated by a NO arrow.

  In step SA12, it is determined whether or not the current timing is the main tempo timing (beat position). This determination is made based on whether or not the main timing signal output in step SB6 of FIG. If the current timing is the beat position of the main tempo, the process proceeds to step SA14 indicated by a YES arrow. If it is not a beat position, the process proceeds to step SA18 indicated by a NO arrow.

  In step SA13, it is determined whether or not the current timing is sub-tempo timing (beat position). This determination is made based on whether or not a sub-timing signal output in step SB12 of FIG. If the current timing is the sub-tempo beat position, the process proceeds to step SA14 indicated by a YES arrow. If it is not a beat position, the process proceeds to step SA18 indicated by a NO arrow.

  In step SA14, the beat position display device (LED) 9L on the operation panel shown in FIG. This is to make the user recognize that the current timing is the beat position, for example. Therefore, not only the blinking of the beat position display device (LED) 9L but also the beat position may be notified to the user by a method such as making a sound like a metronome.

  In step SA15, it is determined whether or not the arpeggio pattern ARP is currently being reproduced. If it is being reproduced, the process proceeds to step SA16 indicated by a YES arrow. If not, the process proceeds to step SA18 indicated by a NO arrow.

  In step SA16, it is determined whether or not the current timing is a scene switching timing. If it is the scene switching timing, the process proceeds to step SA17 indicated by an arrow of YES, and the next scene data SN recorded in the currently reproduced arpeggio pattern ARP is read and reproduced. If it is not the scene data switching timing, the process proceeds to step SA18 indicated by the NO arrow.

  In step SA18, video signal processing is performed on the input video signal based on the current scene data SN or the setting of the operator on the panel. For example, the video signal processing is performed by setting the video composition unit 12, the input selection switch 14, the image quality control unit 15, the display control unit 16, the level control unit 17, the on / off switch 18 and the output selection switch 19 in FIG. This is a process for controlling the display mode of the video signal based on these settings recorded in the scene data.

  In step SA19, processing according to other operations is performed. The process here is a process corresponding to the operation of the various setting operators 7, for example, scene data selection operation, arpeggio pattern selection operation, crossfader operation, input selection, image quality control operation, display control operation, fader operation, This is a process corresponding to an operation for a playback / stop operation or the like. Processing such as recording of scene data SN and recording of arpeggio pattern ARP is also performed here.

  In step SA20, it is determined whether or not there is an instruction to end the video processing apparatus 1. If there is an end instruction, the process proceeds to step SA21 indicated by a YES arrow, and the main process is ended. If there is no end instruction, the process returns to step SA3 indicated by the NO arrow and the subsequent processing is repeated.

  FIG. 5 is a flowchart showing interrupt processing according to this embodiment. This interrupt process is a process for confirming in real time an instruction by the user operating the operation element, and is started with a very short interrupt period (for example, 1 μs to 4 ms).

  In step SB1, interrupt processing is started. In step SB2, it is determined whether or not the trigger switch 8 of FIG. 1 has been operated. When the operation of the trigger switch 8 is detected, the process proceeds to step SB5 indicated by a YES arrow. If the operation of the trigger switch 8 is not detected, the process proceeds to step SB3 indicated by a NO arrow.

  In step SB3, a reference time is detected. For the measurement of the reference time, for example, the relative time count value PTim is set to PTim + α. Here, for example, the value α is set to a value equal to the interrupt cycle of this interrupt process. By setting in this way, the relative time count value can be incremented by a time approximately equal to the actual time every time the interrupt process is activated.

  In step SB4, it is determined whether or not the measurement of the reference time performed in step SB3 has reached the main tempo timing. If the main tempo timing has been reached, the process proceeds to step SB5 indicated by a YES arrow, and if not reached, the process proceeds to step SB7 indicated by a NO arrow.

  In step SB5, the reference time measurement is cleared. For example, the relative time count value PTim is set to “0”. Thereafter, in step SB6, a main tempo timing signal indicating the beat position based on the main tempo is output.

  In step SB7, it is determined whether the sub tempo speed STS is equal to or higher than the main tempo speed MTS (STS ≧ MTS), that is, whether the sub tempo speed STS is the same as or faster than the main tempo speed MTS. If the sub-tempo speed STS is equal to or higher than the main tempo speed MTS, the process proceeds to step SB8 indicated by an arrow of YES. If the sub-tempo speed STS is smaller than the main tempo speed MTS, the process proceeds to step SB10 indicated by an arrow of NO. This determination may be made based on whether or not the tempo conversion ratio TCR is “1” or more. In this case, if the tempo conversion ratio TCR is “1” or more, the process proceeds to step SB8, and if it is less than “1”, the process proceeds to step SB10.

  In step SB8, it is determined whether or not the measurement of the reference time performed in step SB3 has reached the subtempo timing. When the sub tempo timing is reached, the process proceeds to step SB9 indicated by an arrow of YES, and a sub tempo timing signal indicating the beat position by the sub tempo is output. If the sub-tempo timing has not been reached, the process proceeds to step SB14 indicated by a NO arrow, and the interrupt process at the current interrupt timing is terminated.

  In step SB10, the number of outputs of the main timing signal is counted, and in step SB11, it is determined whether or not the counted number has reached a set number (for example, 1 / tempo conversion ratio). When the set number of times has been reached, the process proceeds to step SB12 indicated by a YES arrow. If the set number of times has not been reached, the process proceeds to step SB14 indicated by a NO arrow, and the interrupt process at the current interrupt timing is terminated.

  In step SB12, a subtempo timing signal indicating a beat position based on the subtempo is output. In step SB13, the count of the number of output times of the main timing signal counted in step SB10 is cleared. Thereafter, the process proceeds to step SB14, and the interrupt process at the current interrupt timing is terminated.

  As described above, according to the embodiment of the present invention, it is possible to generate the sub tempo (second tempo) by converting the reference main tempo (first tempo) by the conversion ratio. The main tempo and the generated sub tempo can be switched alternately to be used for reproducing an arpeggio pattern or the like.

  Since the sub-tempo is always generated based on the main tempo, even when the tempo is switched and used, the switching timing of scene data or the like can always be matched to the beat position. Therefore, the beat position of the music that is playing at the same time and the timing of video switching are always matched, and effective video change processing can be performed.

  In the above-described embodiment, the description has focused on inputting a video signal and processing the video signal. However, in this embodiment, any signal can be used as long as it can be played back based on the playback tempo. Is also applicable. For example, the present invention can also be applied to audio signals and performance signals such as MIDI.

  In addition to inputting the generated signal in real time by streaming, the input signal may be input by reading data or signals stored in advance in various storage media or the like.
