Description

Specification

Slide operation device, information processing apparatus and method, and computer program

The present invention relates to an optical disc playback device used by a DJ, a slide operator such as a slide fader provided in a mixer or an effector, and an information processing device and method such as an optical disc playback device used by a DJ, a mixer or an effector. The present invention also relates to a computer program that causes a computer to function as such an information processing apparatus.

Background art

In recent years, recording media capable of recording and reproducing data using digital signals, such as CDs and DVDs, have become widespread. Along with this, information reproduction devices that perform specific reproduction processing due to digital signals are being developed.

[0003] For example, on a CD or DVD, a plurality of music (that is, content data) forces are recorded in association with each other. More specifically, for example, it is recorded as a plurality of data groups distinguished by each music power track number having a predetermined reproduction time. For this reason, the DJ optical disc playback apparatus can perform cue playback that searches and plays back the start address of each music, random playback that arbitrarily changes the playback order of each music, and the like. You can also change the volume of the music to be played and change the tempo. In recent years, an optical disk reproducing apparatus that can reproduce not only music but also video has appeared.

[0004] Furthermore, by using a mixer, it is possible to mix music and the like to be played back by a plurality of optical disk playback devices. For example, a case is assumed in which music played by another optical disc playback device is mixed when music played by one optical disc playback device is flowing from a speaker. In this case, for example, while lowering the volume of music being played by one optical disk playback device and increasing the volume of music being played by another optical disk playback device, it is possible to smoothly connect two different music, Music playback can be continued.

[0005] In addition, various effect effects can be imparted to music played back by using an effector. Depending on the function of the effector, for example, a delay sound can be generated, You can generate a single sound, shake the sound left and right, give the effect that the jet machine periodically rises and falls, or cut the sound periodically.

Disclosure of the invention

Problems to be solved by the invention

However, as described above, for example, an operation button for giving a playback instruction for a video, for example, can only give a playback instruction for the video. Similarly, an operation button for giving a reproduction instruction for music can only give a reproduction instruction for music. Alternatively, an operation button for giving the same reproduction instruction or the like for each of video and music can only give the same reproduction instruction for both video and music. That is, there is a technical problem that it is not possible to separately issue a playback instruction to video and music using a single operation button.

[0008] Not only the above-described video and audio, but also a similar technical problem may occur when an instruction is given for a plurality of pieces of information.

[0009] Examples of problems to be solved by the present invention include the above. It is an object of the present invention to provide a slide operator, an information processing apparatus and method, and a computer program that can suitably give instructions to a plurality of pieces of information. Means for solving the problem

[0010] (Slide controller)

In order to solve the above-mentioned problem, the first slide operator of the present invention is operated so as to slide and move in both directions on a prescribed trajectory, and at least of a plurality of element information included in the predetermined target information First defining means for defining one parameter according to the position on the orbit, and (0 defining the parameter of the first element information of the plurality of element information, or GO the plurality of element information Different from the first element information

Switching means for switching the operation of the first defining means so as to define the parameter of the second element information.

[0011] According to the first slide operator of the present invention, the user defines the first defining means bidirectionally on a predetermined trajectory (for example, in the left-right direction or the up-down direction when viewed by the user force). slide Operated to move. The operation of the first defining means defines at least one parameter of a plurality of element information included in the predetermined target information or specifying the target information according to the position of the first defining means on the trajectory. . Here, the target information is intended to indicate the information to be operated by the first defining means, for example, content information including video content information and music content information, and fragrance including perfume A and perfume B. Specific examples include scent information and character information indicating characters that can be transformed into form A and form B, respectively. In this case, for example, video content information, music content information, fragrance A, fragrance B, form A, and form B are examples of element information.

[0012] In particular, in the first slide operator, the operation of the first defining means is the operation of defining the parameter of the first element information of the plurality of element information and the plurality of element information by the operation of the switching means. Of the second element information can be switched to the operation that defines the parameter of the second element information.

[0013] Thereby, the user can also define each parameter of the plurality of element information when defining the parameter by operating one first defining means. Specifically, in other words, it can be said that one different first function has two different functions. Thus, it is possible to suitably instruct each of a plurality of pieces of information such as video data and music data.

[0014] In particular, in an information processing apparatus that requires quick operation, such as a DJ player or mixer, a plurality of first defining means are operated to define each parameter of a plurality of element information. There is no need. This leads to an advantage that each parameter of a plurality of element information can be defined if the user operates the first defining means with one hand. In other words, the first slide operator has a great advantage that a quick operation can be performed with one hand.

[0015] Furthermore, the above-described configuration can be employed using the i-th defining means such as a slide fader (for example, a volume fader, which is described later). For this reason, it is possible to enjoy the above-described various benefits without impairing the user's operational feeling.

[0016] In order to solve the above-described problem, the second slide operator of the present invention is operated so as to slide in both directions on a specified trajectory, and includes a plurality of elements included in predetermined target information. First defining means for defining at least one parameter of information according to a position on the orbit, and (0 individually specifying the parameter of the first element information of the plurality of element information, Or GO of the first defining means so as to collectively define the first element information of the plurality of element information and the second element information different from the first element information. Switching means for switching the operation.

[0017] According to the second slide operation element of the present invention, the first defining means is provided in the same manner as the first slide operation element.

[0018] In particular, in the second slide operator, the operation of the first defining unit is caused by the operation of the switching unit, the operation of individually defining the parameter of the first element information among the plurality of element information, and the plurality of operations. The operation is switched between the first element information of the element information and the operation that collectively defines the parameters of the second element information different from the first element information. That is, the operation of the first defining means is to individually specify the parameter of any one element information of a plurality of element information and each of two or more element information of the plurality of element information. It is possible to switch between operations that collectively define parameters.

[0019] Thereby, the user can define each parameter of the plurality of element information at the same time or simultaneously when defining the parameter by operating one first defining means. The parameter of one element information among the element information can be individually specified. Specifically, in other words, it can be said that one first defining means has two different functions. Thereby, for example, it is possible to suitably instruct each of a plurality of pieces of information such as video data and music data.

[0020] In particular, in an information processing apparatus that requires quick operation, such as a DJ player or mixer, each parameter of a plurality of element information is defined and the parameter of one element information It is no longer necessary to operate a plurality of first defining means in order to define each individually. This is an advantage that if the user operates the first defining means with one hand, the parameters of one element information can be individually defined as appropriate while the parameters of the plurality of element information are collectively defined. Leads to. In other words, the second slide operator has a great advantage if it can be operated quickly with one hand.

Operated by the user in each of the first mode sliding on the road and the second mode different from the first mode, the first defining means is the first defining unit in the first mode. The parameter is defined according to the operation, and the switching means switches the operation of the first defining means according to the operation of the first defining means in the second mode.

[0022] According to this aspect, in addition to the first aspect (that is, the first operation aspect), the first defining means is operated by the user in the second aspect (that is, the second operation aspect). Is done. The first mode is a mode of operation in which the first defining means is slid on the track. The second mode is a mode in which the first defining means is operated in a mode different from the first mode, and details thereof will be described later. Then, the operation of the first defining means is switched according to the operation of the first defining means in the second mode.

[0023] Thereby, the user can specify the parameters of two or more element information of a plurality of element information at the same time or simultaneously by operating one first specifying means. It is possible to individually manipulate the parameter of one element information desired in the information. In other words, it can be said that two different types of functions are given to one first defining means.

Indicates. VJ performs the performance of switching and outputting the video to the screen etc. mainly at events and club parties, selecting the appropriate video on the spot according to the music and planning progress at the venue, and streaming it at the right time Take on that.

[0086] On the other hand, "DJ" indicates that music is selected from the atmosphere of the place and played without a break or the subject. In particular, it is common practice to perform improvisational or predetermined live performances using turntables that can change the pitch (speed) of music, and perform performances such as DJ mixes and scratches. In a mix, the current playing music and the next playing music are smoothly connected, and the floor tension is often maintained by eliminating breaks in the sound.

[0087] In this way, when discriminating between DJ and VJ, devices such as an optical disk playback device, mixer, and effector used by DJ to play music are called "DJ devices". It is preferable that the devices such as the optical disk playback device, the mixer, and the effector used by the VJ to play back the images are referred to as “VJ devices” to distinguish between the two devices.

[0088] However, both DJ and VJ are common in that the atmosphere of the venue is the act of switching and outputting music and video at a good tempo in accordance with the performer's own feeling. Since it is necessary to match the provided music and video, it is also desirable that one person performs both. Even VJ, which is originally good at video, can easily handle music with video if the music changes following the changes in the video. Conversely, even DJs who are primarily music specialists can handle music and video more naturally if the video changes following changes in sound.

[0089] Therefore, in the embodiments described below, a device that can handle video and music by one person at the same time that cannot be handled by one person at the same time (in the following examples, the description is simplified). This is referred to as “DJ equipment” for Light up. In other words, a specific example in which the present invention is applied to a device that provides a simple and comfortable operation for a person who wants to handle both music and video will be described. However, it goes without saying that the present invention may be applied to a device that handles music alone or a device that handles video alone.

[0090] (1) Basic configuration

First, the basic configuration of the DJ playback system 1 according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram schematically showing the basic configuration of the playback system 1 for DJ according to the present embodiment.

As shown in FIG. 1, a DJ playback system 1 according to the present embodiment includes a plurality of optical disk playback devices 2 (specifically, 2a and 2b) and a mixer 3.

The optical disc playback apparatuses 2a and 2b have a function of playing back video data and music data recorded on the optical discs 100a and 100b, respectively. The reproduced video and music are output to mixer 2. The detailed configuration of the optical disc reproducing apparatus 2 will be described later in detail (see FIG. 2).

[0093] The mixer 3 constitutes a specific example of the "information processing apparatus" in the present invention, and combines video data and music data reproduced by the optical disk reproducing apparatuses 2a and 2b, respectively. It has a function (mixing function) to combine it into a single video data and music data. Further, the mixer 3 has a function of giving a predetermined video effect effect and music effect effect to the video data and music data reproduced by the optical disc playback devices 2a and 2b, as necessary. The video data and music data to which the video effect effect and the music effect effect are added or combined into one by the mixer 3 are output to an external output device such as a display or a speaker. As a result, the video and music are played back on the external output device.

[0094] Subsequently, the basic configuration of the optical disc playback apparatus 2 according to the present embodiment will be described with reference to FIG. FIG. 2 is a block diagram conceptually showing the basic structure of the optical disc reproducing apparatus 2 in the example.

As shown in FIG. 2, the optical disc playback apparatus 2 includes an optical pickup (PU: Pick Up) 210, R

F (Radio Frequency) amplifier 211, spindle motor 212, servo mechanism 213, Backup servo circuit 214, content data decoding unit 215, decoding unit 216, control data decoding unit 217, spindle servo circuit 218, external output terminal 260, system controller 220, memory 221, and operation unit 240 and a display unit 250 are provided.

The optical pickup 210 is for reading content data including video data and music data and control data from the optical disc 100, and includes a semiconductor laser device, various lenses, an actuator, and the like. More specifically, the optical pickup 210 irradiates the optical disc 100 with the laser beam LB with a predetermined power. In addition, a PD (Photo Detector) sensor for receiving the reflected light of the laser beam LB from the optical disk 100 is provided, and the received reflected light is output to the RF amplifier 211 as a read signal.

The optical pickup 210 is configured to move in the radial direction of the optical disc 100 according to a tracking error signal by an actuator, a slider, etc. (not shown) driven by the control of the servo mechanism 213. The focus is controlled by changing the focus of the laser beam LB in accordance with the focus error signal under the control of the servo mechanism 213.

The RF amplifier 211 generates an RF signal based on the read signal output from the optical pickup 210, and outputs the generated RF signal to each of the content data decoding unit 215 and the control data decoding unit 217. The RF amplifier 211 also has a focus error signal and an optical pickup 210 for controlling the focus when the optical pickup 210 irradiates the optical disc 100 with the laser beam LB based on the read signal from which the optical pickup 10 is also output. Generates an error signal such as a tracking error signal for controlling tracking when the optical disc 100 is irradiated with the laser beam LB. The generated error signal is output to the pickup servo circuit 214.

The spindle motor 212 is configured to rotate the optical disc 100 at a predetermined speed while receiving spindle servo from the spindle servo circuit 218.

The servo mechanism 213 moves the optical pickup 210 in the radial direction of the optical disc 100 based on the tracking servo control signal output from the pickup servo circuit 214. In addition, based on the focus servo control signal output from the pickup servo circuit 214, the objective lens included in the optical pickup 210 is moved along the optical axis of the laser beam LB. Let

The pickup servo circuit 214 generates a focus servo control signal and a tracking servo control signal for controlling the servo mechanism 213 based on the error signal output from the RF amplifier 211. The generated focus servo control signal and tracking servo control signal are output to the servo mechanism 213. In other words, the servo mechanism 213 is feedback controlled based on the error signal output from the RF amplifier 211 that suppresses the occurrence of a focus error or tracking error.

[0102] The content data decoding unit 215 generates a stream signal including a video stream and an audio stream by decoding the RF signal output from the RF amplifier 211. The generated stream signal is output to the decoding unit 216.

[0103] Decoding unit 216 decodes the stream signal and generates a reproduction signal. The generated reproduction signal is output to the mixer 3 via the external output terminal 260.

The control data decoding unit 217 generates control data for controlling the reproduction of content data by decoding the RF signal output from the RF amplifier 211. The control data includes, for example, TOC data recorded in the lead-in area of the optical disc 100, synchronization data recorded in the stream signal, and subcode that includes time lapse information when content data is played back. Data is an example. The generated control data is output to the system controller 220 and used to control the reproduction of the content data.

[0105] The spindle servo circuit 218 detects an error in the synchronous data with respect to the rotation speed of the spindle motor 212 instructed by the system controller 220, and feedback-controls the rotation of the spindle motor 212 to suppress the occurrence of the error. .

The system controller 220 includes a microprocessor (MPU), and centrally controls the operation of the entire optical disc playback apparatus 2 by executing a system program (or firmware or the like) that is set in advance.

[0107] The memory 221 includes a RAM area for temporarily storing various data necessary for the operation of the optical disc playback apparatus 2, a ROM area for storing a system program for defining the operation of the system controller 220, and the like. And In addition, an operation unit 240 and a display unit 250 are connected to the system controller 220. Instruction data from various operation keys provided in the operation unit 240 is output to the system controller 220, and the system controller 220 controls the reproduction of the content data according to the instruction data. Further, the system controller 220 controls the display operation on the display unit 250.

The operation unit 40 includes a jog dial 241, a pulse counter 242, and a display unit 250.

[0110] The jog dial 241 is a disk-shaped operation key that is rotatable in both directions. When the user or the like operates the jog dial 241 while appropriately changing the rotation direction and rotation speed, forward playback and reverse playback can be set according to the rotation direction, and further, the speaker or the like can be set according to the rotation speed. Now you can change the tone of music played on headphones!

[0111] Note that the above-described forward reproduction is the same as when the analog record such as LP is rotated in the forward direction to reproduce the image or music, and the content data on the optical disc 100 is recorded in the order in which they are recorded. Say to play. Therefore, as the jog dial 241 is rotated in the clockwise direction, the video is reproduced in the direction along the reproduction time axis, and the music is reproduced as a normal sound. In this embodiment, forward playback is also performed when the jog dial 241 is stopped!

[0112] On the other hand, the reverse playback described above is the reverse of the recorded order of the content data on the optical disc 100, as in the case of playing an image or music by rotating an analog record in the reverse direction. Say to play in order. In other words, since video and music are recorded continuously (analog recording) in analog records, rotating the analog record in the reverse direction will play the video and music in the reverse direction, Unlike the music, onomatopoeia is played, but when the jog dial 241 is rotated counterclockwise, the individual content data digitally recorded on the optical disc 100 is played in the reverse order. As a result, your force will generate the same onomatopoeia as if you were playing the analog record in the reverse direction!

[0113] By providing the same function as reverse playback of analog records in this way, For example, when a user or the like repeatedly rotates the jog dial 241 in the clockwise direction and the counterclockwise direction quickly, a so-called “scratch sound” (a pseudo sound such as “Kyukyu” or “Gashagasha”) can be generated. When a so-called disc jockey player operates the jog dial 241 to generate the above-described scratch sound or the like, it is possible to perform editing for generating rap music or the like using CD or DV D. Yes.

[0114] The pulse counter 242 detects the rotation speed (or angular velocity) of the jog dial 241 by counting the pulse width (or the number of pulses, etc.) of the pulses generated as the jog dial 241 rotates. Power! ] Detect the direction of rotation of the jog dial 241 based on the pulse generated when the jog dial 241 is rotated. The detected rotation direction and rotation speed of the jog dial 241 are output to the system controller 220. As a result, the system controller 220 recognizes the operation amount of the jog dial 24 1 operated by the user or the like.

[0115] The display unit 250 displays various information associated with the reproduction of video and music included in the content data. The display unit 250 includes a display panel such as a liquid crystal display or a fluorescent tube, and displays various types of information under the control of the system controller 220. For example, the display unit 250 displays the track number of the currently played video or music, the elapsed time of the currently played video or music (ie, the current playback time), or the current optical disc playback device 2. The total number of tracks of video and music recorded on the loaded optical disc 100 is displayed. In addition, the display unit 250 displays a wave display of the beat density of music along the playback time axis. Alternatively, the signal intensity for each frequency band of the currently played music may be displayed in waves.

[0116] Of course, the display content in the display 2 section 50 described here is a specific example, and it goes without saying that various other information may be displayed.

Next, with reference to FIG. 3, the basic configuration of the mixer 3 according to the present embodiment will be described. Here, FIG. 3 is a plan view conceptually showing the basic external configuration of the mixer 3 according to the present embodiment.

As shown in FIG. 3, the mixer 3 includes an input terminal 301, an input terminal 302, an equalizer rotary volume 311, an equalizer rotary volume 312, and an equalizer.

[0120] The input terminal 302 is a terminal for inputting video and music output from the optical disc playback apparatus 2b. Hereinafter, the video data and music data input to the mixer 3 via the input terminal 302 are referred to as CH2 (channel 2) video data and music data.

[0121] The equalizer rotary volume 311 is operated by the user to adjust the level of the high frequency range of the music data of CH1. For example, turning the equalizer rotary volume 311 clockwise (ie, to the right) can increase the high-frequency range of the CH1 music data. On the other hand, turning the equalizer rotary volume 311 counterclockwise (that is, to the left) can reduce the high frequency level of the CH1 music data.

[0122] The equalizer rotary volume 312 is operated by the user to adjust the mid-range level of the CH1 music data. For example, turning the equalizer rotary volume 312 clockwise (that is, to the right) can increase the mid-range level of CH1 music data. On the other hand, turning the equalizer rotary volume 312 counterclockwise (that is, to the left) can reduce the midrange level of the CH1 music data.

[0123] Rotary volume for equalizer 313 is the low frequency level of CH1 music data Is operated by the user to adjust. For example, if the equalizer rotary volume 313 is turned clockwise (ie, clockwise), the bass level of the CH1 music data can be increased. On the other hand, if the equalizer rotary volume 313 is turned counterclockwise (that is, leftward), the low frequency level of the CH1 music data can be reduced.

[0124] The equalizer rotary volume 314 is operated by the user to adjust the level of the high frequency range of the music data of CH2. For example, if the equalizer rotary volume 314 is rotated clockwise (ie, clockwise), the high frequency level of the CH2 music data can be increased. On the other hand, if the equalizer rotary volume 314 is turned counterclockwise (ie, leftward), the high frequency level of the CH2 music data can be reduced.

[0125] The equalizer rotary volume 315 is operated by the user to adjust the mid-range level of the CH2 music data. For example, turning the equalizer rotary volume 315 clockwise (ie, in the right direction) can increase the mid-range level of the CH2 music data. On the other hand, turning the equalizer rotary volume 315 counterclockwise (that is, to the left) can reduce the level of the midrange of CH2 music data.

[0126] The equalizer rotary volume 316 is operated by the user in order to adjust the bass level of the CH2 music data. For example, if the equalizer rotary volume 316 is turned clockwise (ie, clockwise), the bass level of the CH2 music data can be increased. On the other hand, if the equalizer rotary volume 316 is turned counterclockwise (that is, leftward), the bass level of the CH2 music data can be reduced.

[0127] The slide fader 321 constitutes a specific example of the "slide operator" in the present invention. The output level of at least one of the CH1 video data and music data (in other words, the brightness or volume etc.) ) To be adjusted by the user. For example, if the knob 321a (an example of “first regulating means” in the present invention) provided in the slide fader 321 is powered upward, the output level of the video data and music data of CH1 is increased. Can be made. On the other hand, if the knob 321a of the slide fader 321 is moved downward, the output level of the video data and music data of CH1 can be reduced. The operation of sliding the knob 321a provided in the slide feeder 321 in the vertical direction corresponds to a specific example of “operation in the first mode” in the present invention. Further, when the slide fader 321 is a specific example of the “slide operator” in the present invention, each of the CH1 video data and music data is a specific example of the “element information” in the present invention. The output level force is a specific example of the “parameter” in the present invention.

[0128] As will be described later, the slide feeder 321 is configured to be operable in a mode different from the mode of sliding in the vertical direction in FIG. Depending on the operation in a mode different from the vertical sliding mode, the output level of each of CH1 video data and music data is increased, the output level of CH1 video data alone is increased or decreased, or CH1 The output level of a single music data can be increased or decreased.

The slide fader 322 constitutes one specific example of the “slide operator” in the present invention, and is operated by the user to adjust the output level of the video data and music data of CH2. For example, if the knob 322a of the slide fader 322 (a specific example of the “first defining means” in the present invention) is powered upward, the output level of CH2 video data and music data can be increased. Can be made. On the other hand, if the knob 322a provided in the slide fader 322 is driven downward, the output level of the video data and music data of CH2 can be reduced. The operation of sliding the knob 322a included in the slide fader 322 in the vertical direction corresponds to a specific example of “operation in the first mode” in the present invention. Further, when the slide fader 322 is a specific example of the “slide operator” in the present invention, a specific example of the “element information” in the present invention is configured. The output level constitutes one specific example of the “parameter” in the present invention.

[0130] As will be described later, the slide feeder 322 is configured to be able to be operated in a mode different from the mode of sliding in the vertical direction in FIG. Depending on the operation in a mode different from the vertical slide mode, the CH2 video data and music data output levels may be increased or decreased, or the CH2 video data unit output level may be increased or decreased. Or increase or decrease the output level of CH2 music data alone.

[0131] The crossfader 323 constitutes one specific example of the "slide operation element" in the present invention, and the ratio of combining the video data of CH1 and the video data of CH2 and the music data of CH1 and CH2 It is operated by the user to adjust the ratio of synthesizing with the music data. For example, when the knob 323a (one specific example of the “first defining means” in the present invention) provided in the crossfader 323 is moved to the leftmost side, the video data and music data of CH1 and the video data and music data of CH2 are Synthesized at a ratio of 100%: 0%. That is, only the CHI video data and music data are output to the external output device connected to the mixer 3. After that, as the knob 323a of the crossfader 323 moves to the right side as well, the CH1 video data and music data ratio decreases and the CH2 video data and music data ratio increases. For example, when the knob 323a provided in the crossfader 323 is moved to the middle position, the video data and music data of CH1 and the video data and music data of CH2 are combined at a ratio of 50%: 50%. In other words, CH 1 video data and music data and CH 2 video data and music data are combined at a ratio of 1: 1, and then output to an external output device connected to the mixer 3. For example, when the knob 323a of the crossfader 323 is moved to the rightmost side, the CHI video data and music data and the CH2 video data and music data are combined at a ratio of 0%: 100%. Is done. In other words, only the video data and music data of CH2 are output to the external output device connected to Power Mixer 1-3. The operation of sliding the knob 323a included in the crossfader 323 in the left-right direction corresponds to a specific example of “operation in the first mode” in the present invention. When the crossfader 323 is a specific example of the “slide operator” in the present invention, each of the video data and the music data constitutes a specific example of the “element information” in the present invention. The synthesis ratio constitutes one specific example of the “parameter” in the present invention.

[0132] As will be described later, the cross feeder 323 is configured to be operable in a mode different from the mode of sliding in the left and right directions in FIG. Depending on the operation in a mode different from the mode of sliding in the horizontal direction, the ratio of combining the video data and music data of CH1 with the video data and music data of CH2 respectively can be adjusted, or C You can adjust the ratio of combining the video data of H 1 and the video data of CH 2 alone, or adjust the ratio of combining the music data of CH 1 and the music data of CH 2 alone. .

The indicator 324 and the indicator 325 constitute a specific example of “display means” in the present invention, and include, for example, an LED. The indicator 324 and the indicator 325 indicate, for example, the power of the crossfader 323 that is the operation target force of the video data and the music data, or the power of the video data alone or the music data alone. Specifically, for example, when the crossfader 323 adjusts the ratio of combining the video data and music data of CH1 with the video data and music data of CH2, respectively, the indicator 324 and the indicator 325 Each of these lights up. For example, if the ratio of combining the crossfader 323 power CH1 video data and CH2 video data alone is adjusted, the indicator 324 goes off and the indicator 325 lights up. For example, when the crossfader 323 adjusts the ratio of synthesizing the CH1 music data unit and the CH2 music data unit, the indicator 324 is turned on and the indicator 325 is turned off.

[0134] The hold button 326 constitutes a specific example of "second defining means" in the present invention.

For example, when the crossfader 323 is selected as an operation target, it is operated by the user in order to define the playback mode of video data or music data. For example, when the operation target of the crossfader 323 is a single video data, it is operated by the user in order to define the playback mode of the music data. On the other hand, for example, when the operation object of the crossfader 323 is a single piece of music data, it is operated by the user in order to define the playback mode of the video data.

In FIG. 3, the indicator 324 and the indicator 325 and the hold button 326 described above are the force provided to the crossfader 323. In addition to or in place of this, the slide fader 321 and the slide Needless to say, a similar configuration could be provided for fader 322.

The effect rotary volume 331 is operated by the user in order to set the type of the video effect effect to be added to the video data. For example, the image periodically blinks The video effect effect that causes the image to swell and the video effect effect that periodically swells the image are set. Of course, various other video effect effects may be set.

[0137] The effect rotary volume 332 is operated by the user in order to set a channel of video data to which a video effect is applied. In other words, it is operated by the user to select whether to apply the video effect effect to the CH1 video data or to apply the video effect effect to the CH2 video data.

[0138] The effect rotary volume 333 is operated by the user to set a first parameter indicating the degree of the video effect effect to be added to the video data (for example, the intensity or periodicity of the effect outside the video effect). . For example, the first parameter may be set larger by rotating the effect rotary volume 333 clockwise. On the other hand, the first parameter may be set smaller by rotating the effect rotary volume 333 counterclockwise.

[0139] The effect rotary volume 334 is operated by the user to set the second parameter indicating the degree of the video effect effect to be added to the video data (for example, the strength or periodicity of the effect outside the video effect). . For example, the second parameter may be set larger by rotating the effect rotary volume 334 clockwise. On the other hand, the second parameter may be set smaller by rotating the effect rotary volume 334 counterclockwise.

[0140] The cue button 336 displays the video effect effect set by the effect rotary volume 331, the effect rotary volume 332, the effect rotary volume 333, and the effect rotary volume 334, as actual video data. It is operated by the user in order to indicate the timing to be given. When the cue button 336 is pressed, the video effect set by the effect rotary volume 331, the effect rotary volume 332, the effect rotary volume 333, and the effect rotary volume 334 is actually displayed as video data. The video with the video effect added is displayed on the display.

[0141] Rotary volume for effects 341 is a music effect effect to be added to music data The user operates to set the type. For example, a music effect effect that generates a delay sound, a music effect effect that generates an echo sound, a music effect effect that generates an echo sound according to the pitch, and the like are set. Of course, other music effects can be set, of course.

[0142] The effect rotary volume 342 is operated by the user to set a channel of music data to which a music effect effect is applied. In other words, it is operated by the user to select whether to apply the music effect effect to the CH1 music data or to apply the music effect effect to the CH2 music data.

[0143] The effect rotary volume 343 is operated by the user to set a third parameter indicating the degree of the music effect effect to be added to the music data (for example, the intensity or periodicity of the effect outside the music effect). . For example, the third parameter may be set larger by rotating the effect rotary volume 333 clockwise. On the other hand, the third parameter may be set smaller by rotating the effect rotary volume 333 counterclockwise.

[0144] The effect rotary volume 344 is operated by the user to set the fourth parameter indicating the degree of the music effect effect to be added to the music data (for example, the intensity or periodicity of the effect outside the music effect). . For example, the fourth parameter may be set larger by rotating the effect rotary volume 334 clockwise. On the other hand, the fourth parameter may be set smaller by rotating the effect rotary volume 334 counterclockwise.

[0145] The cue button 346 is the actual music data set by the effect rotary volume 341, the effect rotary volume 342, the effect rotary volume 343, and the effect rotary volume 344. It is operated by the user in order to indicate the timing to be given. When the cue button 346 is pressed, the music effect set by the effect rotary volume 341, the effect rotary volume 342, the effect rotary volume 343, and the effect rotary volume 344 is actually converted into music data. Music with music effect effect flows from the speaker. [0146] The display unit 361 includes a liquid crystal display, for example, and displays an operation state in the mixer 3. For example, information related to video data and music data input to the mixer 3 (for example, BPM, performance time, etc.) and information related to added video effect effects and music effect effects may be displayed. ,.

[0153] Specifically, the channel fader 374 is controlled by the AV interlocking selection unit 382 according to the operation of the slide fader 322 in a mode other than the slide movement in the left-right direction in FIG. Adjust the output level of each video data and music data, (ii) Adjust the output level of the single CH 2 video data, or (iii) Adjust the output level of the single CH2 music data. The video data or music data whose output level has not been adjusted by the fader 322 is determined depending on whether or not a hold button (not shown) provided for the slide fader 322 is pressed, for example, a predetermined value described later. Preferably, the AV interlocking selection unit 382 constitutes one specific example of the “switching means” in the present invention.

Then, the video data and music data of CH2 whose output level is adjusted are output to channel selection section 375.

[0155] In response to the operation of the effect rotary volume 332, the channel selection unit 375 designates the channel of the video data to which the video effect is to be applied, and outputs the video data of the designated channel to the effect selection unit 376 To do. For example, if the effect rotary volume 332 is selected to apply the video effect effect to the CH1 video data, the channel selection unit 375 converts the CH1 video data output from the channel fade unit 373 into the effect selection unit. Output to 376. On the other hand, if the effect rotary effect 332 has been selected to be applied to the CH2 video data by the rotary rotary volume 332, the channel selector 375 will select the CH2 video data to which the channel fader 374 output will be output. Output to part 376.

[0156] Similarly, the channel selection unit 375 designates a music data channel to which a music effect effect should be applied in accordance with the operation of the effect rotary volume 342, and effects selection is performed on the music data of the designated channel. Output to part 376. For example, if it is selected to apply a music effect effect to the CH1 music data by the rotary rotary volume 342, the channel selector 375 sends the CH1 music data output from the channel fader 373 to the effect selector Output to 376. On the other hand, the effect rotary volume 342 is used to convert music effects to CH2 music data. If it is selected that the effect is to be applied, the channel selector 375 outputs the CH2 music data output from the channel fader 374 to the effect selector 376.

The effect select unit 376 outputs the video data and music data output from the channel select unit 375 to the video / music effect unit 378. At the same time, the video effect effect to be applied is set according to the operation of the effect rotary volume 331. In addition, according to the operation of the effect rotary volume 341, the music effect effect to be applied is set.

[0158] The parameter setting unit 377 sets the first parameter and the second parameter of the video effect effect to be added to the video data in accordance with the operation of the effect rotary volume 333 and the effect unitary volume 334. The set first parameter and second parameter are output to the video “music effect unit 378”.

[0159] Similarly, the parameter setting unit 377 sets the third and fourth parameters of the music effect effect to be added to the music data in accordance with the operation of the effect rotary volume 343 and the effect rotary volume 344. To do. The set third and fourth parameters are output to the video 'music effect unit 378.

[0160] The video 'music effect unit 378 displays the video effect effect set by the effect selection unit 376 in a manner corresponding to the first parameter and the second parameter set by the parameter setting unit 377. Give to data. Similarly, the video / music effect unit 378 applies the music effect effect set by the effect selection unit 376 to the music data in a manner corresponding to the third parameter and the fourth parameter set by the parameter setting unit 378. To do. The video data to which the video effect effect is applied and the music data to which the music effect effect is applied are output to the crossfader unit 380.

[0161] Note that the timing at which the video effect effect is actually added to the video data is the timing at which the cue button 337 is pressed. Similarly, the timing at which the music effect effect is actually added to the music data is the timing at which the cue button 347 is pressed.

[0162] The crossfader unit 380 is composed of at least one of CH1 video data and music data at a composition ratio corresponding to the operation of the crossfader 323 in the vertical direction in FIG. Are combined with at least one of the video data and music data to form one video data and music data. The video data and music data formed into one are output to an external output device such as a display or a speaker, and output as video or music.

[0163] The cross-fader unit 380, in particular, is controlled by the AV interlocking selection unit 383 according to the operation of the cross-fader 323 in a mode other than the slide movement in the vertical direction in FIG. Set the composition ratio of each of music data and CH2 video data and music data, set the composition ratio of G0CH1 video data and CH2 video data alone, or (iii) CH1 video data alone Set the composition ratio of the music data of CH2 alone. At this time, it is preferable that the video data or music data for which the synthesis ratio is not set by the cross-fader 323 is synthesized at a predetermined ratio described later, for example, depending on whether or not the hold button 326 is pressed. . The AV interlocking selection unit 383 constitutes a specific example of “switching means” in the present invention.

[0164] This allows the user to operate the single slide fader 321 to actually select the output level while selecting at least one of the video data and music data of CH1 as the target for adjusting the output level. Can be adjusted. In other words, the user operates one slide fader 321 to output the output level of CH 1 video data and music data, the output level of CH 1 video data alone, or the output level of CH 1 music data alone. However, the output level can be appropriately adjusted so as to obtain a desired level. In other words, the user operates one slide fader 321 to adjust the output level by linking the video data and music data or without linking the video data and music data, respectively. The output level can actually be adjusted while appropriately selecting whether to adjust the output level alone. As described above, the user operates the single slide fader 321 to select the data to be operated by the slide fader 321 and to actually perform the operation on the selected data (in other words, Play command).

[0165] Similarly, by operating one slide fader 322, the user actually adjusts the output level while selecting at least one of the video data and music data of CH2 as the target for adjusting the output level. can do. In other words, the user can By operating Idfader 322, the output level of CH2 video data and music data, the output level of CH2 video data alone, or the output level of CH2 music data alone is output to the desired level. The level can be adjusted as appropriate. In other words, the user operates one slide fader 322 to adjust the output level by linking the video data and the music data, or without linking the video data and the music data, respectively. The output level can actually be adjusted while appropriately selecting whether to adjust the output level alone. In this way, the user operates the single slide fader 322 to select the data to be operated by the slide fader 322 and to actually perform the operation on the selected data (in other words, Play command).

[0166] Similarly, the user operates one crossfader 323 to select at least one of video data and music data as an object for which a composition ratio is to be set, and to actually set the composition ratio. Can be synthesized. In other words, the user operates one kufu swader 323 to combine the CH1 video data and music data respectively, the H2 video data and music data composition ratio, the CH1 video data alone, and the CH2 video. Video data and music data can be actually synthesized while appropriately setting the composition ratio with the data alone or the composition ratio between the music data of CH 1 and the music data of CH2. In other words, the user operates one crossfader 323 to set the composition ratio by linking the video data and music data, or by itself without linking the video data and music data. It is possible to actually synthesize video data and music data at the set composition ratio while appropriately selecting whether to set the composition ratio. In this way, the user operates the single crossfader 323 to select the data to be operated by the crossfader 323, and actually operates the selected data (in other words, playback) Give instructions).

[0167] Thereby, the user can relatively easily instruct the video data and the music data separately for the video data and the music data while linking the video data and the music data. Can do.

[0168] In particular, the user operates the DJ mixer 3 that requires quick operation. It is not necessary to operate a different operator different from the fader in order to change the operation target of the current fader (in other words, the slide operator). This leads to the advantage that if the user operates the fader with one hand, the operation target of the fader can be changed! That is, the mixer 3 according to the present embodiment has a great advantage when a quick operation can be performed with one hand.

[0169] Furthermore, the above-described configuration can be adopted using slide operators such as the slide fader 321, the slide fader 322, the crossfader 323, and the like. For this reason, it is possible to receive the above-described various benefits without impairing the operational feeling of the user who is familiar with the operational feeling of the existing mixer 3.

In the above-described embodiment, the example in which the present invention is applied to the mixer 3 has been described. If the optical disk reproducing device 2 includes a slide operation element, the present optical disk reproducing device 2 is also subjected to the present invention. The invention may be applied. Alternatively, the present invention may be applied to other information devices as long as the information device includes a slide operator.

[0171] In the above-described embodiment, the operation for selecting the operation object of the slide fader has been described. However, the present invention is not limited to this. For example, use one slide fader to set the type of video effect or music effect to be added to video data or music data, and to set the video effect or music effect to video data or music data. The first parameter, the second parameter, the third parameter, and the fourth parameter may be set to indicate the degree. Even when such a configuration is employed, the same configuration as that of the slide fader 321, the slide fader 322, and the crossfader 323 described above may be employed. In addition, the configuration described above may be applied to the rotary volume.

[0172] Specifically, for example, the slide fader described above may be used when adjusting the parameters of a single piece of video data. Thus, by operating the slide fader in the second mode (for example, the mode shown in FIGS. 5 to 14 described later), for example, the brightness, saturation, RGB ratio, size, Which parameter to adjust, such as effect rhythm, effect change mode, flash effect frequency, and playback speed And operating the slide fader in the first mode (for example, the normal mode, for example, the mode of sliding in the left-right direction), the selected at least

One parameter can be adjusted. For example, using one slide fader, only one parameter can be adjusted, or any two or more parameters can be adjusted together.

[0173] Alternatively, for example, the slide fader described above may be used when adjusting parameters of a single piece of music data. Thus, by operating the slide fader in the second mode, for example, parameters such as music volume (in other words, output level), tempo, key and effect (delay sound, echo sound, flanger, etc.) In addition to selecting whether to adjust the deviation, it is possible to adjust at least one selected parameter by operating the slide fader in the first mode.

[0174] Of course, the same applies to a combination of video data and music data. For example, one slide fader can be used to adjust at least one of the multiple parameters of the video data, to adjust at least one of the multiple parameters of the music data, or to the video data At least one of the plurality of parameters and at least one of the plurality of parameters of the music data can be adjusted together.

[0175] As described above, when appropriately switching the parameters to be adjusted between the video data parameters and the music data parameters, for example, the video data parameters and the music data parameters are changed as follows. You may adjust while making it cooperate.

[0176] For example, when the video size and the music volume are selected as adjustment targets, each parameter may be adjusted so that the video size increases as the volume increases. For example, when the slide fader is moved in the left direction, the volume may be reduced and the image size may be reduced. On the other hand, for example, if you move the slide fader to the right, increase the volume and the size of the video.

[0177] For example, if the degree of the effect that the video blinks and the music tempo are selected as adjustment targets, adjust the parameters so that the faster the music tempo, the faster the video blinking tempo May be. For example, move the slide fader to the left When moving, the music tempo may be slowed and the flashing tempo of the video may be slowed. On the other hand, for example, when the slide fader is moved in the right direction, the music tempo may be accelerated and the blinking tempo of the video may be increased.

[0178] For example, when the degree of effect for dividing a video and a music key are selected as adjustment targets, each parameter may be adjusted so that the video is further divided as the key is raised. For example, when the slide fader is moved in the left direction, the key may be lowered and the number of divided images may be reduced. On the other hand, for example, if you move the slide fader in the right direction, raise the key and reduce the number of divided images.

[0179] For example, when the degree of video effect and the volume of music are selected for adjustment, each parameter is adjusted to increase the degree of video effect as the volume is increased. May be. For example, when the slide fader is moved in the left direction, the volume may be reduced and the degree of video effect may be reduced. On the other hand, for example, when the slide fader is moved in the right direction, the volume may be increased and the degree of video effect may be increased.

[0180] For example, when the video effect level and the music tempo are selected as adjustment targets, each parameter may be adjusted to change the video effect level as the volume is increased. Good. For example, in the case of an effect that rotates an image, the volume of the image may be reduced and the rotation speed of the image may be decreased by moving the slide fader in the left direction. On the other hand, for example, by moving the slide fader in the right direction, the volume may be increased and the rotation speed of the image may be increased. Alternatively, the slide fader may be moved in the left direction to reduce the volume and slow down the video playback speed. On the other hand, for example, by moving the slide fader in the right direction, the volume may be increased and the video playback speed may be increased. Of course, other effects may be adjusted in various ways.

[0181] For example, when the video effect level and the music effect level are selected as adjustment targets, each parameter is set so that the higher the music effect level, the higher the video effect level. May be adjusted. For example, the rest of video and music In the case of effects that leave reverberation, the reverberation level remaining in the music may be reduced and the reverberation level remaining in the video may be reduced by moving the slide fader in the left direction. On the other hand, for example, by moving the slide fader in the right direction, the reverberation level remaining in the music may be increased and the reverberation level remaining in the video may be increased. Of course, other effects may be adjusted in various ways.

[0182] Note that, as described above, by moving the slide fader in the second mode, the force configured to select at least one selected parameter has a relative number of selected parameters. In the case where the number increases, a selection operator for selecting a parameter may be provided separately. In this case, for example, by operating the slide fader in the second mode, one of video data and music data is selected as the parameter adjustment target, and adjustment is performed by operating the selection operator. It may be configured to actually adjust the parameters by further selecting the parameters to be controlled and operating the slide fader in the first manner.

[0183] Further, the operation target of the slide fader is not limited to video data or music data.

[0184] Specifically, for example, when a slide fader is used in an illumination device, the position of the illumination to be turned on and the color of the illumination are selected using the slide fader, and the brightness of the illumination is also selected. You may comprise so that a height etc. may be adjusted. For example, the position of the lighting to be turned on by operating the slide fader in the second mode and the color of the lighting at that time are selected, and the selected lighting is operated by operating the slide fader in the first mode. Configure it to adjust the brightness.

[0185] Alternatively, for example, when a slide fader is used in an air conditioner, the slide fader may be used to adjust temperature, humidity, and other parameters. For example, by operating the slide fader in the second mode, select at least one of temperature, humidity, and other parameters to be adjusted, and select the slide fader by operating in the first mode. May be configured to adjust at least one of measured temperature, humidity and other meters.

[0186] Alternatively, for example, when a slide fader is used in a blending device such as a fragrance The slide fader may be used to adjust the type of fragrance to be blended, the blending ratio, and the like. For example, the type of fragrance is selected by operating the slide fader in the second mode, and the blend ratio of the selected fragrance is adjusted by operating the slide fader in the first mode. You can configure it.

In short, a plurality of elements specified by the settable parameters can be set as the operation targets of the slide fader according to the present embodiment. (2) Specific operation details

Next, with reference to FIG. 5 to FIG. 14, the actual configuration of the slide fader 321 and the slide fader 322 and the actual configuration of the crossfader 323 will be described. Here, each of FIG. 5 to FIG. 14 is a plan view, a side view, or a perspective view conceptually showing an actual configuration of the crossfader 323. In the following explanation, the explanation will be made with attention paid to the cross feeder 323, but it goes without saying that the same explanation can be applied to the slide fader 321 and the slide fader 322.

[0188] As shown in Fig. 5 (a), the knob 323a provided in the crossfader 323 slides along the left and right directions in Fig. 5 (a) (this corresponds to the left and right directions in Fig. 3). Moving. Depending on the operation of the crossfader 323 along the left-right direction in Fig. 5 (a), the composition ratio of at least one of CH1 video data and music data and at least one of CH2 video data and music data is Is set.

[0189] The directional force of L1 in Fig. 5 (a) As shown in Fig. 5 (b) showing the crossfader 323 when observed, the knob 323a is positioned in the vertical direction in Fig. 5 (b) (this is In line with the vertical direction in Fig. 5 (a) and in line with the direction of the near side force in FIG. 3 and the direction of the far side force toward the near side) stepwise or You may comprise so that it can move continuously. In this case, according to the position of the knob 323a in the vertical direction in FIG. 5 (b), at least one of video data and music data is selected as a target for which the composition ratio is to be set.

[0190] For example, as shown on the left side of Fig. 5 (b), when the knob 323a is pushed down to the lowest position, the video data and the music data are selected as targets for setting the composition ratio. Is done.

[0191] For example, as shown in the middle side of Fig. 5 (b), the knob 323a shown on the left side of Fig. 5 (b) is pulled up one step (in other words, in Fig. 5 (b)). The state of knob 323a shown on the right In this state, the video data alone is selected as the target for which the composition ratio is to be set.

[0192] For example, as shown on the right side of Fig. 5 (b), when the knob 323a shown in the middle of Fig. 5 (b) is pulled up one step, the composition ratio is set. A single piece of music data is selected as the target.

[0193] Specifically, the crossfader 323 detects the position of the knob 323a in the left-right direction in Fig. 5 (a) and the position of the knob 323a in the up-down direction in Fig. 5 (b). In order to achieve this, the configuration shown in FIG. That is, as shown in FIG. 3 (c), the cross fader 323 includes a slide position detection unit 323b including a encoder and a pressing stage detection unit 323c, for example.

[0194] The slide position detector 323b detects the position of the knob 323a in the left-right direction in Fig. 5 (a). The detected position substantially indicates the synthesis ratio. That is, the detected position defines the composition ratio. For this reason, the composition ratio in the mouth swather unit 380 is set according to the detected position.

[0195] The pressing stage detection unit 323c detects the position of the knob 323a in the vertical direction in FIG. 5 (b). The detected position substantially indicates an object for which the composition ratio is to be set. Under the control of the AV interlocking selection unit 383 according to the detected position, the crossfader part 380 sets (0CH1 video data and music data respectively, and CH2 video data and music data synthesis ratios, (Ii) Set the composition ratio of CH1 video data alone and CH2 video data alone, or (m) Set the synthesis ratio of CH 1 video data alone and CH2 music data alone.

[0196] In FIGS. 6 to 14 below, the crossfader 323 also has the position of the knob 323a in the left-right direction in FIG. 5 (a) and the knob 32 3a in the left-right direction in FIG. 5 (a). Needless to say, it has a configuration for detecting an operation mode of the knob 323a in a mode other than the sliding movement. That is, the crossfader 323 includes a detection unit that detects an operation mode of the knob 323a in a mode other than the sliding movement of the knob 323a in the left-right direction in FIG. 5A in place of the pressing stage detection unit 323c. ing.

[0197] In the configuration shown in Fig. 5 (c), when the operation target of the crossfader 323 is switched. In addition, a signal indicating the position of the knob 323a in the left-right direction detected by the common slide position detection unit 323b and a signal indicating the position of the knob 323a in the up-down direction detected by the pressing stage detection unit 323c are detected. However, a plurality of slide position detectors 323b may be provided corresponding to the position of the knob 323a in the vertical direction instead of the pressing stage detector 323c. In other words, according to the position of the knob 323a, the slide position detection unit 323b to which the knob is connected is mechanically switched (for example, the switch mechanism that connects the knob 323a and the plurality of slide position detection units 323b is switched). It may be configured. In this case, the crossfader unit 380 determines whether each of the slide position detection unit 323b outputs a signal (0CH1 video data and music data, CH2 video data and music data, respectively). Set the composition ratio, (ii) set the composition ratio of the CH1 video data unit and the CH2 video data unit alone, or (iii) set the composite ratio of the CH2 video data unit to the CH2 music data unit. Set.

[0198] Also, as shown in Fig. 6 (a) showing the crossfader 323 when the directional force of L1 in Fig. 5 (a) is observed, the knob 323a can be pushed down in Fig. 6 (a). It may be configured. In other words, the knob 323a shown in FIG. 6 (a) includes a push mechanism that is pressed downward and then returns upward. In this case, at least one of video data and music data is selected as a target for which the composition ratio is to be set according to the number of times the knob 323a is pressed downward.

[0199] For example, as shown in FIG. 6 (b), the number of times the knob 323a is pressed downward is 1, 4 times,

····· 3n—2 times (where n is an integer greater than or equal to 1), the music data alone is selected as the target for setting the composition ratio. When the number of times the knob 323a is pressed downward is 2, 5,..., 3n-1 times, the single image data is selected as an object for which the composition ratio is to be set. When the number of times the knob 323a is pressed downward is 3, 6,..., 3n, video data and music data are respectively selected as targets for setting the composition ratio.

[0200] Further, as shown in Fig. 7 (a) showing the crossfader 323 when the directional force of L1 in Fig. 5 (a) is observed, the knob 323a is configured to tilt with its lower part or the like as a fulcrum. Also good. In this case, the degree of inclination of the knob 323a (that is, the knob 323a in the horizontal direction as viewed from the user) Depending on the degree of inclination, at least one of video data and music data is selected as a target for which a composition ratio is to be set.

[0201] For example, as shown on the left side of Fig. 7 (a), when the knob 323a is inclined to the left side, video data alone is selected as an object for which the composition ratio is to be set. As shown in the middle of Fig. 7 (a), when the knob 323a is not tilted, video data and music data are selected as targets for setting the composition ratio. As shown on the right side of FIG. 7 (a), when the knob 323a is tilted to the right, the music data alone is selected as the target for which the composition ratio should be set.

[0202] Further, as shown in Fig. 7 (b) showing the crossfader 323 when viewed from the direction L3 in Fig. 5 (a), the knob 323a is configured to tilt with its lower part as a fulcrum. Also good. In this case, depending on the degree of inclination of the knob 323a (that is, the degree of inclination of the knob 323a in the front-rear direction or the up-down direction as viewed from the user), the video data and the music data are to be set as targets for setting the composition ratio. At least one is selected.

[0203] For example, as shown on the left side of FIG. 7B, when the knob 323a is inclined to the left side, video data alone is selected as a target for which the composition ratio is to be set. As shown in the middle of FIG. 7 (b), when the knob 323a is not tilted, video data and music data are selected as targets for setting the composition ratio. As shown on the right side of FIG. 7 (b), when the knob 323a is tilted to the right, the music data alone is selected as the target for which the composition ratio should be set.

[0204] Also, as shown in Fig. 8 showing the crossfader 323 when the directional force of L2 in Fig. 5 (a) is observed, the knob 323a is arranged in the horizontal direction of Fig. 8 (that is, the horizontal direction of Fig. 3 ) In a different direction (specifically, the vertical direction in FIG. 8 and coincides with the vertical direction in FIG. 3). May be. In this case, for example, according to the position of the knob 323a in the vertical direction, at least one of video data and music data is selected as a target for which the composition ratio is to be set.

For example, as shown in FIG. 8 (a), when the position of the knob 323a in the vertical direction is at the reference position (in other words, the position force of the knob 323a is at the center position in the vertical direction), Video data and music data are selected as targets for which the ratio should be set. Is done. As shown in FIG. 8 (b), when the position of the knob 323a in the vertical direction is relatively on the lower side, the video data alone is selected as a target for setting the composition ratio. As shown in FIG. 8 (c), when the position of the knob 323a in the vertical direction is relatively higher, the music data alone is selected as an object for which the composition ratio is to be set.

[0206] Further, as shown in Fig. 9 showing the crossfader 323 when the directional force of L2 in Fig. 5 (a) is observed, the crossfader 323 may be configured so that the knob 323a rotates. Good. In this case, according to the degree of rotation of the knob 323a, at least one of video data and music data is selected as a target for which the composition ratio is to be set.

[0207] For example, as shown in Fig. 9 (a), the position of the knob 323a in the vertical direction is at the reference position (in other words, when the knob 323a is not rotating, the composition ratio should be set) As shown in Fig. 9 (b), when the knob 323a is rotated to the left with respect to the reference, the composition ratio should be set. As shown in Fig. 9 (c), the video data alone is selected as the target, and when it is rotating to the right with respect to the knob 323a force reference, the composition ratio should be set as A single piece of music data is selected.

[0208] Further, as shown in Fig. 10 (a) showing the crossfader 323 when the directional force of L2 in Fig. 5 (a) is observed, the knob 323a may have a contact sensor 327 on the outer surface thereof. Good. In this case, at least one of video data and music data is selected as a target for which the composition ratio should be set according to the number of times the user's hand or finger touches the outer surface of the knob 323a.

[0209] For example, as shown in FIG. 10 (b), the number of times that the user's hand or finger touches the outer surface of the knob 323a is once, four times, 3m-2 times (where m is If it is an integer equal to or greater than 1, a single piece of music data is selected as a target for which a composition ratio is to be set. If the user's hand or finger touches the outer surface of the knob 323a 2 times, 5 times, 3m-1 time, the video data is the target for which the composition ratio should be set. A single unit is selected. If the user's hand or finger touches the outer surface of the knob 323a 3 times, 6 times, 3m times, video data and music data should be set as targets for setting the composition ratio. Are selected. [0210] Also, as shown in Fig. 11 (a) representing the crossfader 323 when the directional force of L2 in Fig. 5 (a) is also observed, the knob 323a is provided with a contact sensor on each of a plurality of portions on the outer surface thereof. 327a and 327b may be provided. In this case, at least one of video data and music data is selected as a target for which a composition ratio is to be set according to the position where the user's hand or finger contacts the knob 323a.

[0211] For example, as shown in FIG. 11 (b), when the user's hand or finger touches the upper part of the knob 323a (ie, the upper part in FIG. 11 (a)), the composition ratio is set. The music data alone is selected as the target to be processed. When the user's hand or finger touches the lower part of the knob 323a (ie, the lower part in FIG. 11 (a)), the video data alone is selected as the target for which the composition ratio is to be set. When the user's hand or finger touches both the upper and lower portions of the knob 323a, the video data and the music data are selected as targets for setting the composition ratio.

[0212] Also, as shown in Fig. 12 (a), which represents the crossfader 323 when the directional force of L2 in Fig. 5 (a) is also observed, the knob 323a force two harms ij knobs 323a-1 and 323a- It may be configured so as to divide into two. Specifically, the knob 323a may be divided into two divided knobs 323a-1 and 323a-2 along the left-right direction in FIG.

[0222] In the above-described embodiment, in the operation of the knob 323a in a mode different from the slide movement in the left-right direction in Fig. 3, (0 video data and music data selection and GO video data are selected. In this example, it is possible to configure the system so as to perform more segmentation, or even less segmentation. Even in this case, the position of the knob 323a, the amount of rotation, the degree of tilt, the number of presses, the number of contacts, the contact position, etc., can be set according to the number of cuts. The various benefits described above can be enjoyed.

[0223] (3) Use of hold button

Subsequently, the relationship between the position of the knob 323a and the displayed image when the hold button 326 is used will be described with reference to FIGS. FIG. 15 to FIG. 17 are plan views conceptually showing the relationship between the position of the knob 323a and the displayed image.

[0224] In the following description, when both video data and music data are selected as targets for setting the composition ratio, a single piece of music data is newly selected as a target for setting the composition ratio. An explanation will be given of the operation when it is done. In addition, the video data of CH1 shows the video shown in Fig. 15 (a), and the video data of CH2 shows the video shown in Fig. 15 (b).

FIG. 16 (a) shows a state in which video data and music data are selected as targets for which the composition ratio is to be set. In this case, CH1 video data and CH2 video data are combined into one video data at a composite ratio corresponding to the position of knob 323a in the left-right direction, and the combined single video data is connected to mixer 3. Appears on the displayed display. Specifically, as shown in Fig. 16 (a), knob 323a is at the end of its operating range. Because it is located on the left side, the video data of CH 1 is displayed on the display!

[0226] Here, when the hold button 326 is pressed !, NA! /, In the state (in other words, in the OFF state), the music data alone is newly selected as an object to set the composition ratio. Suppose. In other words, it is assumed that the state in which the composition ratio is set by linking the video data and the music data is switched to the state in which the composition ratio of the music data alone is set without linking the video data and the music data. In this case, the composition ratio of the music data is set according to the position of the knob 323a in the left-right direction. On the other hand, the composition ratio of the video data may be set to a default ratio, for example, regardless of the position of the knob 323a in the left-right direction. Here, for example, the video data of CH1 and the video data of CH2 may be combined at a ratio of 0%: 50%. In other words, the knob 323a may be regarded as having moved near the middle of its operating range. In this case, as shown in FIG. 16 (b), the video data of CH1 is displayed in the right half and the video data of CH2 is displayed in the left half. The default ratio may be set in advance by the user, or may be preset by the manufacturer when the mixer 3 is manufactured.

On the other hand, it is assumed that the music data alone is newly selected as a target for which the composition ratio is to be set in a state where the hold button 326 is pressed (in other words, in the ON state). In this case, the composition ratio of the music data is set according to the position of the knob 323a in the left-right direction. On the other hand, the composition ratio of the video data may be set according to the position of the knob 323a when a single piece of music data is newly selected as a target for which the composition ratio is to be set. In other words, with regard to the composition ratio of video data, the composition ratio at the time when a single piece of music data is newly selected as a target for which the composition ratio should be set may be maintained as it is. In other words, with regard to the composition ratio of video data, the composition ratio of music data alone can be changed without linking the video data and music data from the state where the composition ratio is set by linking the video data and music data. The composition ratio at the time of switching to the setting state may be maintained as it is. Specifically, as shown in FIG. 17B, the video data of CH1 is displayed on the display regardless of the position of the knob 323a.

[0228] Thus, from the state where the composition ratio is set by linking the video data and the music data. Even if it is switched to a state in which the composition ratio is set independently without linking the video data and music data, the video data and music data from the state in which the composition ratio is set independently without linking the video data and music data. Can be switched to a state in which the composition ratio is set in conjunction with, and it is possible to suitably eliminate the inconvenience that video data and music data are reproduced in an unintended manner.

Note that, as shown in FIGS. 18 and 19, the slide fader 321 and the slide fader 322 may be attached, and similarly to the cross fader 323, a hold button may be provided. 18 and 19 are plan views conceptually showing the relationship between the position of the knob 321a (or knob 322a) and the output levels of the video data and the music data.

[0230] In the following explanation, when video data and music data are selected as targets for adjusting the output level, music data alone is newly selected as a target for adjusting the output level. An explanation will be given of the operation when it is done. The video data of CH1 is the video shown in Fig. 15 (a), and the video data of CH2 is the video shown in Fig. 15 (b).

FIG. 18 (a) shows a state in which video data and music data are selected as targets whose output levels are to be adjusted. In this case, as shown on the right side of FIG. 18 (a), the output levels of the video data and the music data are adjusted according to the position of the knob 32la in the vertical direction. It appears on the display.

[0232] Here, when the hold button 326 is pressed,!, NA! /, In the state (in other words, in the OFF state), the music data alone is newly selected as the object whose output level should be adjusted. For example, In other words, it is assumed that the state in which the output level is adjusted by linking the video data and the music data is switched to the state in which the output level of the music data alone is adjusted without linking the video data and the music data. In this case, the output level of the music data is adjusted according to the position of the knob 321a in the vertical direction. On the other hand, the output level of the video data may be adjusted to be, for example, a default level regardless of the vertical position of the knob 321a. Here, as shown on the right side of FIG. 18 (b), for example, adjustment may be made so that the output level force of the video data is obtained.

[0233] On the other hand, in the state where the hold button 326 is pressed and pressed (in other words, in the ON state), Assume that a single piece of music data is newly selected as an object whose output level should be adjusted. In this case, the output level of the music data is adjusted according to the position of the knob 321a in the left-right direction. On the other hand, the output level of the video data may be adjusted according to the position of the knob 321a at the time when a single piece of music data is newly selected as an object whose output level is to be adjusted. In other words, with regard to the output level of the video data, the output level at the time when a single piece of music data is newly selected as an object whose output level should be adjusted may be maintained as it is. In other words, as shown on the right side of Fig. 19 (b), regarding the output level of video data, the video data and music data are linked from the state in which the video data and music data are linked to adjust the output level. The output level at the time of switching to the state of adjusting the output level of the music data alone without changing it will be maintained.

[0234] With this, even if the output level is adjusted by linking the video data and the music data, and the output level is adjusted independently without linking the video data and the music data, Video data and music data are not intended even if the output level is adjusted independently of video data and music data without switching video data and music data. The inconvenience reproduced in the embodiment can be suitably eliminated.
