DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0015]
FIG. 1 is a block diagram showing the overall configuration of a signal processing apparatus according to an embodiment of the present invention. This apparatus is configured as, for example, a video mixer apparatus.
[0016]
The CPU 12 uses the operation program and various setting data stored in the ROM 13 and controls the video mixer apparatus using the RAM 14 as a work area. The RAM 14 temporarily stores various data including flags.
[0017]
More specifically, by detecting an operation event of various operators on the operation panel 16 via the bus 11, the parameter value is transmitted to the video signal processing unit 21 in order to apply a video effect and perform a mixing operation. Make settings (device settings). The storage unit 15 is configured by a flash memory or the like. Scene data (processing content setting information) to be described later is generated by this apparatus, or downloaded from an external apparatus via the interface (PC / IO) 18 and stored in the storage unit 15.
[0018]
Reference numerals 19 (1) to 19 (n) denote analog / digital conversion units (digital video decoders), which are connected to the video signal processing unit 21 via frame buffers 20 (1) to 20 (n). The analog / digital converters 19 (1) to 19 (n) convert an analog composite signal (video signal, color burst, composite synchronization signal) format video signal into a digital data composite signal. At this time, the video signal is separated into a luminance signal (Y signal), a color difference signal (Cb signal), and a color difference signal (Cr signal).
[0019]
Since the video signals of the plurality of input channels 1 to n are not synchronized, the video signals of the input channels 1 to n are captured in the respective frame buffers 20 (1) to 20 (n), and the synchronization timing is adjusted. To the video signal processing unit 21.
[0020]
The video signal processing unit 21 is realized by, for example, a DSP (Digital Signal Processor). The video signal processing unit 21 is operated by the CPU 12 to arbitrarily select an input video signal in which parameter setting values, mixing signal paths, and the like are set, and to mix and output in real time.
[0021]
A video output circuit (digital video encoder) 22 generates an analog composite signal from the Y signal, Cb signal, and Cr signal of the video signal output from the video signal processing unit 21, and outputs the analog composite signal to a video display device (not shown). A screen corresponding to the output video signal is displayed. In the above video display device, when the video display position overlaps between channels, the video with the younger channel number is controlled to be displayed above (front).
[0022]
The interface (PC / IO) 18 is connected to an external personal computer or the like. The external personal computer can display the operation element on the display screen of the display device and can control the video signal processing unit 21 in the same manner as the CPU 12. The display unit 17 displays various types of information such as parameter value setting states and scene data contents. A timer 23 is connected to the CPU 12, and the timer 23 measures the interrupt time and various times in the timer interrupt process.
[0023]
Here, the scene data is data that defines the content of signal processing relating to each of signal processing parameters (processing elements) such as image quality adjustment and image position adjustment, and is a group of operators related to signal processing at a certain setting timing. The setting state is defined collectively. In the present embodiment, a plurality of types of scene data are stored in the storage unit 15 and desired scene data are individually read out at an arbitrary timing, or read in a predetermined order by an arpeggiator stream function described later. By doing so, it is possible to easily reproduce the setting state of the operator group related to the signal processing or to control a complicated video effect that changes with time.
[0024]
FIG. 2 is a diagram showing a part of the operation panel 16. In the operation panel 16, processing elements (parameters) that are similar / related items are grouped and grouped.
[0025]
For example, the group 31 includes an operator group that assigns input ports to input channels. In the group 31, the operator group is divided into four corresponding to each of the four channels, and they are arranged in parallel in the horizontal direction as shown in FIG. The vertical lines connected between the following groups 32 to 36 indicate that they correspond to the same input channel. In the group 31, two or more input channels can be associated with one input port.
[0026]
The group 32 includes an operator group for setting, for each channel, whether or not to assign an input effect such as negative / positive, black and white inversion, and presence / absence of input. The group 33 includes an operator group for performing setting for each channel such as offset gain (Trim), hue adjustment (Hue), and color gain (Color). The group 34 includes an operator group for performing setting for each channel such as image position movement (Position), image size (Size), and distortion effect (Dist). The group 35 includes an operator group for performing setting for each channel such as frame multi-division (Div) (sheets), color reduction effect (Reduce), and frame rate (FL.Rate) (sheets / second). The controls in the group 36 are faders (sliders) that set a gain (reflection level) common to Y and C for each channel. The group 37 includes a change time operator 48.
[0027]
The groups 31 to 37 are grouped together so as to be intuitively easy to use. For example, the groups 32, 33, and 35 are related to image quality adjustment, and the group 34 is related to image arrangement adjustment. It has become a thing. Moreover, the range of the group is surrounded by a predetermined frame line so that it can be easily understood visually. In addition to the identification by the frame line, the identification may be facilitated by unifying the mark, the color of the panel surface, the shape of the operation element, and the like.
[0028]
Each group is provided with an operator (EKB) to which no processing element is assigned, and a desired processing element (which may overlap with an element in another group) can be arbitrarily assigned to it. It can be done. Note that grouping is an example, and other groupings are possible. Further, processing elements not included in any group (other elements in the operator groups 51 and 52, etc.) may be included in any group.
[0029]
In addition, the operation panel 16 includes a main fader 53 for adjusting the output level of the mixed video signal, a scene data button 38 to which scene data is assigned, an arpeggiator stream button 39 to which data of an arpeggiator stream is assigned, and other control elements. 52 is provided. Further, a rotary operator 50, a tempo operator 49, and other operator groups 51 are also provided. It should be noted that the push type operators such as the scene data button 38 and the arpeggiator stream button 39 have built-in LEDs so that the selection state can be visually recognized.
[0030]
Here, the data of the arpeggiator stream is data that defines the order of reading a plurality of types of scene data stored in advance. When the scene data button 38 is turned on, the corresponding single scene data is read out, and parameter value setting (update of the device setting state) in the video signal processing unit 21 is performed based on the read out scene data. ) In real time. When the arpeggiator stream button 39 is turned on, the scene data is read out in a predetermined order, and the device setting state of the video signal processing unit 21 is updated every time accordingly.
[0031]
The change time operator 48 sets the switching time between successive scene data in the arpeggiator stream. The scene data reading speed can be adjusted by the tempo operator 49 by switching the mode. For example, the reading speed is determined by an average value of a plurality of times (for example, four times) when the tempo operator 49 is tapped with the hand and is hit most recently.
[0032]
Also, the scene data in the arpeggiator stream can be read out by the rotary operator 50 by switching the mode. In the case of the rotary operator 50, the rotation of the rotary operator 50 can be replaced with the passage of time, and read control can be performed. For example, the rotary operator 50 progresses with time in the clockwise direction and takes time with the rotation in the counterclockwise direction. The scene data can be read in the reverse order. In addition, scene data can be assigned to each rotation position of the rotary operator 50 and used instead of the scene data button 38.
[0033]
Although not shown individually, the other operator group 51 includes a crossfader, sync, and the like, and the other operator group 52 includes operators for performing playback, stop, preview, various mode settings, and the like. It is. Although not shown, a display such as an LCD for performing simple display corresponding to the images of channels 1 to 4 and LEDs for indicating various setting states is disposed on the operation panel 16.
[0034]
The various modes set by the other operator group 52 include at least a “scene data creation mode”, an “arpegator stream creation mode”, a “playback mode”, and a “group correspondence mode”. As will be described later, scene data can be newly created and recorded in the scene data creation mode, and arpeggiator stream data can be newly created in the arpeggiator stream creation mode.
[0035]
When creating scene data, after selecting a certain scene data button 38, set values (parameter values) for each processing element (parameter) in the groups 31 to 37, and press the store button 38 (S). Thus, one scene data is created. As a recording mode, the parameter value is overwritten for the same processing element of the same channel, but a configuration may be adopted in which the result is rewritten to the addition result with the new parameter value or the subtraction result. After setting the parameter values for all the processing elements, pressing the store button 38 (S) associates the setting state at that time with the selected scene data button 38. That is, it is stored in the storage unit 15 as scene data.
[0036]
Further, when creating an arpeggiator stream, a certain arpeggiator stream button 39 is selected, the scene data button 38 is pressed in a desired order, and then the store button 39 (S) is pressed to select the selected arpeggiator stream button 39. Is associated with the order setting state of the scene data at that time, and stored in the storage unit 15 as arpeggiator stream data.
[0037]
Note that the recording method of scene data and arpeggiator stream data is not limited to the above-described mode, and may be stored in the storage unit 15 by any method.
[0038]
The operation panel 16 is further provided with recall cancel buttons 40 to 47. The recall cancel buttons 40 to 47 update device settings for some or all processing elements when certain scene data is read and device settings are updated accordingly. It is a control for prohibiting. The recall cancel buttons 40 to 47 are switched between an on state and an off state each time they are operated, and the on state can be recognized by lighting of a built-in LED. Note that the recall cancel buttons 40 to 47 may be configured as switches that are turned on only when pressed by the user and maintained in the off state when released.
[0039]
The prohibit function of the recall cancel buttons 41, 42, 43, 44, 45, 46, 47 works for the setting of the processing elements in the groups 31, 32, 33, 34, 35, 36, 37, respectively. In this embodiment, when a certain recall cancel button is operated, all four channels are targeted for the prohibited function. In particular, the prohibit function of the recall cancel button 40 works for the setting of all the processing elements in the groups 31 to 37. Also, in the group correspondence mode, it works for the setting of all the processing elements included in each group, and when it is not the group correspondence mode, it works only for the processing elements that are currently selected in each group. Note that any processing element assigned in the group by the operator (EKB) is also subject to the recall cancel button prohibition function.
[0040]
FIG. 3 is a signal path diagram illustrating functions of the video signal processing unit 21. The number of input channels (CH) is four, the number of output channels is one, and the description of the preview output channel is omitted.
[0041]
The image quality adjustment units 61 (1) to (4) adjust the image quality of the video signals of the first to fourth input channels, and read the parameter values (reading values) of the processing elements in the groups 32, 33, and 35 shown in FIG. Control based on the scene data that has been output is also included. The image arrangement adjustment units 62 (1) to (4) adjust the image arrangement and size of the first to fourth input channels, and are controlled by the parameter values of the processing elements in the group 34. The gain adjustment units 63 (1) to (4) are controlled by parameter values set by faders in the group 36.
[0042]
The on / off switch sections 64 (1) to (4) define whether or not to output video signals through the gain adjustment sections 63 (1) to (4). The switch sections 65 (1) to (4) define the allocation path from each input channel 1 to 4 to the cross gain adjustment section 66, and one of “A input”, “B input” or “through” is selected. Selected. Connections of video signal inputs in “A input”, “B input”, and “through” indicate that addition synthesis is performed. The cross gain adjusting unit 66 synthesizes and outputs the two video signals assigned to “A input” and “B input” with weights that change in opposite directions. The on / off switch unit 64, the switch unit 65, and the cross gain adjustment unit 66 are controlled by the other operator groups 51 and 52. The connection of the output of the cross gain adjusting unit 66 and the “through” output of each input channel indicates that addition synthesis is performed. The main gain adjustment unit 67 is controlled by the main fader 53.
[0043]
FIG. 4 is a diagram showing a flowchart of the main processing in the present embodiment. This process is started when the power is turned on. Note that an operator scan for detecting the status of each operator on the operation panel 16 is executed by an interrupt process (not shown).
[0044]
First, initialization is executed, that is, execution of a predetermined program is started, various registers are cleared, and initialization is performed (step S401). Next, control setting operation processing shown in FIGS. 5 and 6 to be described later is executed (step S402), then scene control processing in FIG. 8 to be described later is executed (step S403), and video signal processing and output are performed. (Step S404), the process returns to Step S402. In step S404, as a result of the processing in steps S402 and S403, signal processing and output are performed on input signals of four channels in the device setting state updated in the video signal processing unit 21.
[0045]
5 and 6 are flowcharts of the control setting operation process executed in step S401 of FIG.
[0046]
First, it is determined whether or not the scene data creation mode is set (step S501). If not, the process proceeds to step S505. If so, each processing element (scene parameter) is set in the scene data (step S505). S502). That is, as described above, in each of the groups 31 to 37, each time the parameter value of each processing element is changed, the parameter value of the processing element is overwritten, and the recording instruction is issued by pressing the store button 38 (S). (Step S503), the parameter setting state at that time is recorded as scene data in association with the selected scene data button 38 (step S504), and the process proceeds to step S517.
[0047]
Note that one of the processing elements is always selected in each group by the initial setting or the operation in step S502. The processing elements in the selected state are not only subject to parameter value change in this step S502, but are also subject to individual recall cancellation processing to be described later (step S704 in FIG. (Described later in S707).
[0048]
In step S505, it is determined whether or not the arpeggiator stream creation mode is set. If not, the process proceeds to step S509. If so, the scene data button 38 is pressed in the order of reproduction of the desired scene data. The order is set (step S506), and when the recording instruction is issued by pressing the store button 39 (S) (step S507), the scene data order set at that time is set to the selected state. The data is recorded as arpeggiator stream data in association with a certain arpeggiator stream button 39 (step S508), and the process proceeds to step S517.
[0049]
In step S509, it is determined whether or not the scene data button 38 or the arpeggiator stream button 39 has been operated. If it is determined that there is no operation, the process proceeds to step S511. If any operation is performed, the contents corresponding to the buttons 38 and 39 selected by the operation are set as processing targets. (Step S510), the process proceeds to Step S517. Here, scene data or arpeggiator stream data to be reproduced is set as a processing target. In addition, the scene data selected by operating the scene data button 38 can be immediately subjected to a recall cancel process described later. It should be noted that the content corresponding to the selected buttons 38 and 39 may be a target to be post-modified by data modification processing (not shown).
[0050]
In step S511, it is determined whether or not there has been a reproduction start instruction (by pressing the reproduction operator of the other operator group 52) instructing the start of scene data or an arpeggiator stream. If there is no reproduction start instruction, the process proceeds to step S513. On the other hand, if there is, a start flag corresponding to that is set (step S512), and the process proceeds to step S517.
[0051]
In step S513, it is determined whether or not the group correspondence mode has been set by the operation of the other operator group 52. If the group correspondence mode is not set, the process proceeds to step S515. If there is, the group flag is set. (Step S514), the process proceeds to Step S517.
[0052]
In step S515, it is determined whether any one of the recall cancel buttons 40 to 47 is operated. If none is operated, the process proceeds to step S517. If any one is operated, the process proceeds to FIG. A recall cancel process is executed (step S516), and the process proceeds to step S517.
[0053]
In step S517, it is determined whether or not there is another instruction. If there is, an appropriate process is executed (step S518), and this process is terminated. Here, other instructions include, for example, instructions for setting the playback tempo, stopping, previewing, setting instructions for various modes that have not appeared until the previous step, such as a scene data creation mode, an arpeggiator stream creation mode, etc. is there.
[0054]
FIG. 7 is a flowchart of the recall cancel process executed in step S516 of FIG.
[0055]
First, it is determined whether or not the recall cancel buttons 40 to 47 operated this time have been in an off state so far (step S701). If the recall cancel buttons 40 to 47 have been in an off state and are in a group correspondence mode (step S702), With respect to the scene data to be reproduced, a prohibition flag (update prohibition information) is set for all processing elements included in the target group (step S703), and this process ends.
[0056]
Here, the “scene data to be reproduced next” is the scene data (set in step S510 in FIG. 5) in the case of independent scene data reproduction, and in the case of arpeggiator stream reproduction. This is the scene data next to the scene data currently being reproduced (depending on the operation timing of the recall cancel button). The “target group” is a group corresponding to the recall cancel button operated this time. In particular, when the recall cancel button 40 is newly turned on, all of the groups 31 to 37 are “target target”. "Group". For example, when the recall cancel button 43 is operated and the mode is the group correspondence mode, the prohibition flag is set for all of the offset gain, hue adjustment, and color gain that are processing elements in the group 33 that is the target group. Stands.
[0057]
On the other hand, if the recall cancel buttons 40 to 47 operated this time are in the off state and are not in the group correspondence mode (step S702), the prohibition flag is set only for the processing element currently selected in the target group. Standing up (step S704), the process is terminated. For example, when the recall cancel button 43 is operated, the prohibit flag is set only for the offset gain when the offset gain is selected in the group 33 and not in the group correspondence mode. As described above, since any one of the processing elements is always selected in each group, that processing element is a target for setting the prohibition flag.
[0058]
If it is determined in step S701 that the recall cancel buttons 40 to 47 operated this time have not been turned off so far, and if the mode is the group correspondence mode (step S705), all the processes included in the target group The prohibition flag is lowered for the element (step S706), and this process ends. On the other hand, when the mode is not the group correspondence mode (step S705), the prohibition flag is lowered only for the processing element currently selected in the target group (step S707), and this processing is terminated.
[0059]
If “NO” in the step S701, the prohibition flag may be lowered for all the processing elements included in the target group regardless of whether the mode is the group correspondence mode. In that case, the steps S705 and S707 may be omitted, and the step S706 may be executed immediately if “NO” in the step S701.
[0060]
FIG. 8 is a flowchart of the scene control process executed in step S403 in FIG.
[0061]
First, it is determined whether or not the start flag is set (step S801). If it is not set, the process is terminated. If it is set, whether or not the start flag is a flag for instructing the start of the arpeggiator stream. (Step S802). If not, the flag is an instruction to start scene data. Therefore, the process proceeds to step S805. If so, the current temporal position information is calculated (step S803).
[0062]
Here, the temporal position information is calculated by acquiring data of a timer counter that is operating in an interrupt process (not shown). In the interrupt process, the flow is periodically cycled to count by the addition process, and the beat timing is output at the set tempo. Also, data indicating which position is between the beats is calculated and output. This output data is used to automatically switch the scene data when executing the arpeggiator stream.
[0063]
Next, in step S804, scene data is regenerated according to the calculated temporal position information, and the process proceeds to step S805. That is, when interpolation is not necessary, it is necessary to read out scene data (in this case, one) corresponding to the temporal position information based on the arpeggiator stream data and generate the same scene data as it is, and then perform interpolation. In this case, the scene data (in this case, plural) corresponding to the temporal position information is read, and the setting value (parameter value) is calculated for each processing element from the positional relationship between the beats. New scene data at is generated.
[0064]
In step S805, the parameter value of the scene data processing element is read. Here, when the process proceeds from step S802, the parameter value of each processing element is read for the scene data selected by the scene data button 38. On the other hand, if the process proceeds from step S804, the parameter value of each processing element is read for the scene data regenerated in step S804.
[0065]
Next, it is determined whether or not a prohibition flag is set on the processing element to be read this time (step S806), and if not, as usual, based on the parameter value of the processing element read this time, The device setting state is updated by newly setting the parameter value in the video signal processing unit 21 (step S807). Thereby, the mode of signal processing is changed according to the scene data. Thereafter, the process proceeds to step S808.
[0066]
In step S807, when interpolation is performed between continuous scene data in the arpeggiator stream and a prohibition flag is set for only one scene data of the continuous scene data for a certain processing element, the overlap between the two is performed. In time, the device setting is changed by an amount corresponding to the degree of participation with respect to the interpolation value of the scene data for which no prohibition flag is set. Alternatively, with respect to such processing elements, the interpolation value may be invalidated, and the device setting of the video signal processing unit 21 may be updated based only on the parameter value of the scene data for which no prohibition flag is set.
[0067]
On the other hand, as a result of the determination in step S806, if the prohibition flag is set in the processing element that is the current reading target, the process proceeds to step S808 without updating the device setting state of the video signal processing unit 21. Thus, the parameter value is not changed for the processing element for which the prohibition flag is set, and is maintained.
[0068]
In step S808, it is determined whether or not reading of all the processing elements is completed. If not completed, the process returns to step S805. If completed, the process is terminated.
[0069]
Accordingly, when the user wants to apply the recall cancel process, the user may perform the following operation.
[0070]
First, when scene data is selected and played back, the scene data button 38 is used to select the scene data → the recall cancel buttons 40 to 47 are used to set a prohibition flag for a desired group (in this case, the group correspondence mode is required). The operation is performed in the order of instructing reproduction with the reproduction button of the other control group 52.
[0071]
If the scene data is to be continuously played back with the arpeggiator stream, the scene data playback order is set with the arpeggiator stream button 39, and the playback is instructed with the playback button of the other operator group 52. By operating the recall cancel buttons 40 to 47 while the scene data immediately before the scene data to which the user wants to apply is operated, a prohibition flag is set for a desired group (in this case, the group correspondence mode is set as necessary. Set).
[0072]
According to the present embodiment, for the processing elements for which the prohibition flag is set among the processing elements in the scene data, the update of the device setting of the video signal processing unit 21 is prohibited regardless of the scene data. The usability can be improved by making it possible to determine at any time whether or not the setting state for signal processing can be updated.
[0073]
In addition, processing elements are grouped into multiple groups by grouping similar and related elements, and the recall cancel button can be set in groups, making it easy to grasp the processing elements intuitively, and in the group-compatible mode. For example, in the group support mode, it is convenient to set a prohibition flag for related processing elements at once. In the non-group support mode, a prohibition flag is individually set for each processing element. This is useful when setting up. In addition, since the recall cancel button 40 that functions as all cancel is provided, it is convenient to set a prohibition flag for the processing elements in all the groups 31 to 37 at a time. Therefore, it is easy to use.
[0074]
Further, since the prohibition flag can be set differently for each scene data even for the same processing element, the video signal processing unit 21 only for some of the processing elements in the continuous scene data in the arpeggiator stream. It is also possible to perform control so that the device setting is not updated, and fine-grained video effect control can be realized without impairing the function of the arpeggiator stream.
[0075]
In the present embodiment, for the processing element for which the prohibition flag is set, the device setting update prohibition works for all channels. However, a specific channel can be specified and a specified channel (a plurality of channels) can be specified. It may be configured such that the update prohibition is applied only to the above. Alternatively, not only grouping for each processing element but also grouping for each channel, a recall cancel button may be provided for each channel group.
[0076]
In the present embodiment, the scene data read out by operating the scene data button 38 or the arpeggiator stream button 39 can be subject to device setting update prohibition. However, the present invention is not limited to this. For example, The same may be applied to scene data read by the operation of the rotary operator 50.
[0077]
In the present embodiment, the processing coping signal is a video signal. However, the present invention is not limited to this, and can be applied to an audio signal, for example.
[0078]
In the present embodiment, the case where the recall cancellation process is applied to the scene data read from the storage unit 15 is illustrated, but the present invention is not limited to this, for example, via the interface (PC / IO) 18 or the like. The present invention may also be applicable to scene data read from other connected storage devices.
[0079]
It should be noted that the same effect may be obtained by reading a storage medium storing a control program represented by software for achieving the present invention into the apparatus, in which case the data is read from the storage medium. The program code itself realizes the new function of the present invention, and the storage medium storing the program code constitutes the present invention. Further, the program code may be supplied via a transmission medium or the like, and in that case, the program code itself constitutes the present invention. As a storage medium in these cases, a portable medium such as an optical disk and a floppy (registered trademark) disk can be used in addition to a ROM and a hard disk.
[0080]
