Technical field

The present invention relates to an input device that displays a mixed state of a plurality of video signals, a touch panel integrated display device, a video signal processing device, an input method, and a display method. Background art

Conventionally, there has been known an audio signal processing device that simultaneously adjusts two types of audio signals by moving a moving member (knob, gripping portion) within a moving range having both ends of A and B as both ends. (For example, Patent Document 1). This type of audio signal processing apparatus is generally called a “cross-feeder”, and the volume of the first audio signal increases as the moving member moves to the A end B end, and conversely from the B end A The volume of the second audio signal is increased as the moving member moves toward the end. In other words, the mixing ratio of the two types of audio signals can be determined according to the position of the moving member.

Patent Document 1: Japanese Patent Laid-Open No. 2004-5987

On the other hand, in recent years, it has been known that the above-mentioned audio signal processing device can be applied to a video signal to determine a mixing ratio of two types of video signals. This type of video signal processing device is used for video performance by VJ equipment (visual jockey or video jockey (VJ)) that is used to project images in clubs and other venues with many changes. It is desired to be able to skillfully express a variety of images that are often applied to equipment. For this reason, various methods for mixing three or more types of video signals have been proposed. Disclosure of the invention

Problems to be solved by the invention

[0004] By the way, it is indispensable for the operator (VJ) to grasp the mixing state (mixing ratio) of each video signal in order to express various images by mixing multiple video signals. In this case, since the mixed state cannot be confirmed by the ear like voice, a means for indicating the mixed state is required. If you are mixing two types of video signals, Depending on the position of the moving member, the operator can grasp the approximate mixing state, but this is not applicable when mixing three or more types of video signals.

[0005] Therefore, it is conceivable to provide as many faders as the number of video signals and indicate the mixed state of the video signals depending on the position of the moving member of each fader. However, as the number of video signals increases, it becomes difficult to separate the force. End up. However, when the mixing force is indicated by the fader, it is not practical because of physical limitations such as the placement area of the fader. In particular, in devices that require various operations such as the above-mentioned VJ devices, it is inevitable that the area for indicating the mixed state of each video signal with a large number of operators is limited.

In view of the above problems, the present invention provides an input device, a touch panel integrated display device, a video signal processing device, an input device that can more easily understand a mixed state of a plurality of video signals and save space. It is an object to provide a method and a display method.

Means for solving the problem

[0007] The input device of the present invention is configured such that, for a plurality of input video signals, one axis end of a plurality of coordinate axes indicating a mixing ratio of the video signals is aggregated near the center so that the plurality of coordinate axes are radially Place on each coordinate axis! And a display means for displaying the index point of the mixing ratio, and a mixing ratio changing means for changing the mixing ratio of each video signal by moving the position of each index point on each coordinate axis of the display means. It is characterized by reciting.

[0008] Further, in the input method of the present invention, with respect to a plurality of input video signals, one end of a plurality of coordinate axes indicating a mixing ratio of the video signals is aggregated near the center to obtain the plurality of coordinate axes. The mixing ratio of each video signal is changed by moving the index point of the mixing ratio on each coordinate axis.

According to these configurations, the input device for changing the mixing ratio of a plurality of video signals can function as a display unit that indicates the mixing ratio of each video signal. In addition, multiple coordinate axes that indicate the mixing ratio of each video signal are arranged radially, and the mixing ratio of each video signal is indicated by the index point on each coordinate axis. It can be shown easily. Furthermore, by arranging each coordinate axis radially, even if there are many video signals to be mixed, the number of coordinate axes and index points can be increased. Therefore, it is possible to save space (no need to increase the display space).

[0010] In the above input device, the display means displays a radar chart in which each index point on each coordinate axis is connected by a line, and deforms the radar chart as the index point is moved by the mixing ratio changing means. U, prefer to display.

According to this configuration, a mixed state of a plurality of video signals can be shown by deformation (shape and area) of the radar chart having a polygonal force corresponding to the number of input video signals. In this way, by using a radar chart that is one of the commonly used (familiar) graph shapes, it is possible to show a mixed state of a plurality of video signals that are easier to distribute.

[0012] In the above input device, the display means preferably displays an image of each video signal corresponding to each coordinate axis in the vicinity of the axis end opposite to the one axis end of each coordinate axis.

[0013] According to this configuration, the video of each video signal corresponding to each coordinate axis is displayed near the outer radial end of each coordinate axis, so the user confirms the video whose mixing ratio is to be changed. And operability can be improved.

[0014] In the above input device, the video is preferably displayed at a luminance rate corresponding to the mixing ratio of each video signal.

[0015] According to this configuration, each video signal is displayed at a luminance rate corresponding to the mixing ratio of each video signal (the position of the index point on the coordinate axis). The user can confirm whether or not

[0016] In the above input device, the display means preferably displays the video of each video signal and the video of the mixed video signal obtained by mixing the video signals based on the change by the mixing ratio changing means.

[0017] According to this configuration, since the video of the mixed video signal obtained by mixing the video signals is displayed on the same display device on which the video of each video signal is displayed, it is easy for the user to check each video. In addition, the image of the mixed video signal that is output can be recognized without the need for a monitor or the like.

[0018] In the above input device, the mixing ratio changing means shifts the position of the line connecting the index points. When the position of the line is moved, it is preferable to move the positions of the two index points located at both ends of the line.

[0019] According to this configuration, by moving the position of the line connecting the index points, the positions of the two index points located at both ends can be moved simultaneously, so that the operability is good (operation load) Can be reduced).

[0020] When the position of an arbitrary index point is moved to the input device! /, The mixing ratio changing means may enlarge and reduce the radar chart in a similar shape with the movement. In addition, it is preferable to move the positions of all other index points.

[0021] According to this configuration, it is possible to change only the luminance rate (brightness impression) while keeping the mixing ratio of the plurality of video signals constant.

[0022] In the above input device, the mixing ratio changing means can move the position of the line connecting the index points in parallel, and when the position of any line is moved, At the same time, it is preferable to move the positions of all the index points so that the radar chart is enlarged and reduced in a similar manner.

[0023] According to this configuration, since the positions of all the index points can be moved simultaneously by translating the positions of the lines connecting the index points, the operability is good. In addition, it is possible to change only the luminance ratio (brightness impression) while keeping the mixing ratio of multiple video signals constant.

[0024] In the above input device, when at least two of the plurality of coordinate axes are arranged on a straight line, the mixing ratio changing means may change the position of each index point with each video signal. It is preferable to move the position of the index point on the same line as the index point so that the total of the mixing ratio does not change.

[0025] According to this configuration, two related videos are arranged so that the coordinate axes of the video signals are positioned on a straight line, so that a crossfade between the two videos (one of the two videos can be fed). It can fade out and fade in other images to gradually connect the images.

[0026] The input device further includes target index point designating means for designating a target index point to be automatically moved among a plurality of index points, and the mixing ratio changing means includes any index When the position of the point is moved, it is preferable to move the position of the target index point so that the total mixing ratio of each video signal does not change with the movement.

[0027] According to this configuration, for example, when an arbitrary index point corresponds to a video signal of telop display and the target index point is a video other than the telop, crossfading between the telop display and another video is performed. Can be realized. In other words, while fading in one video, Z-fading out other videos, it is possible to fade out Z-fading in at the same time.

[0028] The input device further includes target index point designating means for designating a target index point to be automatically moved among a plurality of index points, and the mixing ratio changing means determines a position of an arbitrary index point. When a fixed amount is moved, it is preferable to move the position of the target index point to the plus side or minus side by a predetermined amount.

[0029] According to this configuration, it is possible to move the position of the target index point by a predetermined amount to the plus side or the minus side as the predetermined index point moves. In other words, it is possible to change the mixing ratio of other video signals by the same amount by operating only one main video signal.

[0030] A touch panel integrated display device of the present invention is characterized by comprising each means in the above input device.

[0031] According to this configuration, since it is a touch panel integrated display device, an arbitrary number of video signals can be input. In other words, since it is not necessary to physically arrange coordinate axes (such as a feeder), the number of coordinate axes to be displayed can be changed according to the number of input video signals.

[0032] The video signal processing apparatus of the present invention is a mixing unit that mixes each video signal based on a change by each unit in the input device, a video signal input unit that inputs a plurality of video signals, and a mixing ratio changing unit. And a mixed video signal output means for outputting a mixed video signal mixed by the mixing means.

[0033] According to this configuration, it is possible to provide a video signal processing device equipped with an input device that can more easily indicate the mixed state of a plurality of video signals and save space.

[0034] In the display method of the present invention, one axis of a plurality of coordinate axes indicating the mixing ratio of the video signal. The plurality of coordinate axes are arranged radially with the ends gathered near the center, and the mixing state of each video signal is displayed by the index point of the mixing ratio on each coordinate axis.

[0035] According to this configuration, a plurality of coordinate axes indicating the mixing ratio of each video signal are arranged radially, and the mixing ratio of each video signal is indicated by the index point on each coordinate axis. The state can be shown intuitively and easily. Furthermore, by arranging each coordinate axis radially, even if there are many video signals to be mixed, it is only necessary to increase the number of coordinate axes and index points (no need to increase the display space).匕 can be planned.

Hereinafter, an input device, a touch panel integrated display device, a video signal processing device, an input method, and a display method according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 (a) is a system configuration diagram of a video signal processing system SY to which the video signal processing device 20 of the present invention is applied. The video signal processing system SY generates one or more DVD players 10 (only one is shown in the figure) that generates a plurality of video signals to be input to the video signal processing device 20, and inputs from the DVD player 10. The video signal processing device 20 that mixes the plurality of video signals thus generated and generates a mixed video signal, and the monitor 30 that displays the mixed video signal output from the video signal processing device 20 also have power.

Note that the device that generates the video signal to be input to the video signal processing device 20 is not limited to the DVD player 10, and may be other devices (such as various video devices and a personal computer). . Further, the function of the DVD player 10 may be built in the video signal processing device 20. Furthermore, the video signal may be a moving image or a still image.

[0040] Further, as an example of the video signal processing device 20, there is a VJ device used for video performance in a club or the like. VJ devices are operated by video performers called visual jockeys or video jockeys (VJs). Responsible for selecting appropriate videos on the spot and playing them in a timely manner in accordance with the progress of music and projects. Therefore, the type of video signal input to the video signal processing device 20 is not limited to a natural image, and it is also preferable to use computer graphics or animation. In addition, it is also preferable to use a video obtained by applying various video effects to these videos (a more diverse and curious mixed video can be obtained). In this case, examples of effective video effects include monochromeization, partial extraction of video, extraction of color components (R, G, B), contour extraction, and the like.

FIG. 1 (b) is a simplified block diagram of the video signal processing device 20. Here, description will be made assuming that four types of video signals (video signals A to D) are input as video signals. The video signal processing device 20 has a touch panel integrated display device (input device) as its main component. ) 21, CPU 22, video signal input interface (video signal input means) 23, mixing means 24, and video signal output interface (video signal output means) 25.

[0042] The touch panel integrated display device 21 has a touch panel on a display device such as an LCD.

(A touch pad) is arranged and integrated, and comprises a mixing ratio changing means 26 and a display means 27. The mixing ratio changing means 26 is for the user to change (specify operation, input operation) the mixing ratio of each video signal input via the video signal input interface 23. The display means 27 displays the video of each input video signal and the video of the mixed video signal mixed by the mixing means 24 in a predetermined area on the touch panel integrated display device 21, and Radar chart 29 (see Fig. 2 etc.) showing the mixing state (mixing ratio) of the signal is displayed.

[0043] "Radar chart" refers to a graph in which the origins of the vertical axes (axis ends on the minimum value side) of a line graph are aggregated in one place and each axis is arranged radially, and the area of the closed line It is possible to grasp the characteristics in the situation of a protrusion (indentation). In the present embodiment, the coordinate axes Z of the number of input video signals are arranged radially, and the mixing ratio of each video signal is indicated by the position of the index point P on each coordinate axis Z. Details will be described later.

The CPU 22 generates a control signal for instructing mixing of each video signal based on the touch position signal generated in response to the operation by the mixing ratio changing unit 26, and outputs this to the mixing unit 24. . Further, the mixed video signal mixed by the mixing unit 24 is output to the display unit 27. Further, the CPU 22 performs overall control of the video signal processing device 20 such as information management based on other user operations and input / output of signals with external devices.

The mixing unit 24 is realized by, for example, a video control device, and determines a mixing ratio of each input video signal based on a control signal input from the CPU 22. Further, based on the determined mixing ratio, a mixed video signal is generated by mixing each video signal, and is output to the video signal output interface 25 and the CPU 22.

Next, the display configuration of the touch panel integrated display device 21 will be described with reference to FIG. 2 and FIG. As shown in both figures, the touch panel integrated display device 21 displays a radar chart 29 indicating the mixed state of the input video signals A to D and a video display for displaying the video of each video signal A to D. Parts Da to Dd and video signals A to D are fader systems And a mixed video display unit Dm for displaying the video of the mixed video signal mixed in.

[0047] The radar chart 29 includes four coordinate axes Za to Zd corresponding to the video signals A to D, and index points Pa to move on the coordinate axes Za to Zd and index the mixing ratio of the video signals A to D. It consists of Pd and the line Lab-Lda connecting each index point Pa-Pd. When the number of input video signals is n (where n is an integer such that n≥2), the number of coordinate axes Z and the number of index points P are n, and the number of lines L is (n-1).

[0048] The user determines an index point P or line L to be operated (moved) by pressing an arbitrary index point P or line L with a pointing device such as a touch pen or a finger. Then, the position of the index point P or line L is changed by moving (dragging) the pressed position in an arbitrary direction. That is, the touch panel integrated display device 21 changes the radar chart 29 in accordance with the position change of the index point P or the line L by the user, and depending on the shape and area, a plurality of input video signals are input. Indicates mixed state.

[0049] In coordinate axes Za to Zd, coordinate axis Za and coordinate axis Zc, coordinate axis Zb and coordinate axis Zd are arranged on a straight line, and the intersection O of these two straight lines is the origin of each coordinate axis Z (the axis on the radial center side) Edge, mixing ratio 0%). However, in this embodiment, if the origin position of each coordinate axis Z overlaps with the intersection point O, it is difficult to move the index point P at the origin position, so the position slightly moved on each coordinate axis Z from the intersection point O is It is the origin of each coordinate axis Z (see Fig. 3). In other words, radar chart 29 in FIG. 3 shows that video signals A to D are all mixed at 0%. In each coordinate axis Z, the end opposite to the origin indicates the mixing ratio of each video signal 100%. That is, the radar chart 29 in FIG. 2 shows that the video signals A to D are all mixed at 100%.

[0050] The video display sections Da to Dd are displayed near the end of each coordinate axis Za to Zd on the maximum value (100%) side so that the user can check the video corresponding to each coordinate axis Z at a glance. Yes. Each video display area Da to Dd is always displayed with a luminance rate of 100%, regardless of the set mixing ratio of each video signal (position of index point P).

[0051] The mixed video display unit Dm displays a video of a mixed video signal obtained by mixing each video signal at a mixing ratio based on the position of the index point P on each coordinate axis Z. Therefore, the example in Figure 2 In the case of, the video signals A to D are all mixed and displayed with a luminance rate of 100%. In addition, as shown in FIG. 3, when the index point P on each coordinate axis Z is at the origin position (indicating 0%), the video signals A to D are all mixed at a luminance rate of 0%. (Fully black screen) is displayed (hidden).

[0052] Next, with reference to FIG. 4 and FIG. 9, a method of changing the mixing ratio of the video signals A to D and a modification of the radar chart 29 accompanying the change will be described. In each figure, (a) shows before the change of the mixing ratio of each video signal, and (b) shows after the change. In addition, for the sake of easy understanding, illustration of the video display parts Da to Dd and the mixed video display part Dm is omitted.

[0053] Fig. 4 (a) shows a radar chart 29 when the video signals A to D are mixed at a mixing ratio of V and a deviation of 100%. When the index point Pb is moved to the left (minus side) in the figure, and the movement end point is at the position shown in (b), the video signal B mixture ratio is changed to 50%. . At this time, the mixing ratio of the video signal B gradually decreases in the mixed video signal display section Dm (see FIG. 2 etc.) as the index point Pb moves (the video B becomes gradually thinner). H) Video is displayed.

[0054] In the mixing ratio changing method shown in FIG. 5 and subsequent figures, the display of the mixed video signal display section Dm naturally changes with the movement of the index point Pb (change of the mixing ratio). In order to avoid explanation, reference to the display of the mixed video signal display section Dm is omitted below.

[0055] Thus, according to the mixing ratio changing method shown in FIG. 4, an arbitrary index point P can be freely moved. In other words, the mixing ratio of any video signal can be freely changed between 0% and 100%. Further, the radar chart 29 is deformed as the index point P is moved, so that the user can intuitively grasp the mixed state of each video signal in a short time. For example, as shown in (a) of the figure, if the radar chart 29 is a well-balanced diamond, it can be recognized that each video signal is mixed at a well-balanced mixing ratio. On the other hand, when a rhombus that is partially indented as shown in (b) of the figure is displayed for a well-balanced rhombus as shown in (a) of the figure, this corresponds to the indented part. It can be recognized that the mixing ratio of video signals is low. In this way, the user can display the radar signal without numerical confirmation (100%, 50%, etc.) and checking the mixing ratio of each video signal. The mixed state of multiple video signals can be grasped at a glance by using only the shape and area of Yart 29.

[0056] Next, the mixing ratio changing method shown in FIG. 5 will be described. Here, the index line P is the connecting line L. FIG. 5 (a) shows a radar chart 29 when the video signals A to D are mixed at a mixing ratio of 100%. When the line Lab is moved in parallel to the dotted line in the figure, the index point Pa and the index point Pb positioned at both ends of the line Lab are moved to the minus side at the same rate. Is possible. Therefore, as shown in (b) of the figure, when the index point Pa is changed to a mixing ratio of 50% as the line Lab moves in parallel, the index point Pb is also changed to a mixing ratio of 50%.

[0057] On the other hand, when the line Led is moved from the state shown in FIG. 5A as indicated by the dotted line (the movement trajectory is curved), the index points positioned at both ends of the line Led with the movement. Pc and index point Pd can be moved to the minus side at different rates depending on the curvature. That is, as shown in FIG. 5B, with the curve movement of the line Lab, for example, the index point Pc can be changed to the mixing ratio 30%, and the index point Pd can be changed to the mixing ratio 80%.

As described above, according to the mixing ratio changing method shown in FIG. 5, the movement of the line L allows the two index points P located at both ends thereof to be moved simultaneously. Can be halved and the operability can be improved. In addition, since the index points P located at both ends can be changed at the same rate or at different rates according to the movement trajectory of the line L, various video expressions can be easily realized.

[0059] It should be noted that the mixing ratio changing method shown in FIG. 4 and the mixing ratio changing method shown in FIG. 5 are combined, and the movement target is the line L only, the index point P only, or the line L and the index point P. Both can be set to either one or the other!

[0060] Next, the mixing ratio changing method shown in FIG. 6 will be described. Here, we show a method of changing only the brightness of the output video while keeping the mixing ratio of each video signal constant. FIG. 6 (a) shows a radar chart 29 when the video signals A to D are mixed at a mixing ratio of 50%. When the index point Pa is moved to the dotted line side (plus side) from the state shown in the figure, all other index points Pb, Pc, Pd are moved to the plus side at the same rate. Can do. Therefore, as shown in the figure (b), the index point Pa If the mixing ratio is changed to 100% with movement, the other three index points Pb, Pc and Pd are also changed to the mixing ratio 100%. That is, in the example shown in the figure, the surface shape of the radar chart 29 can be deformed in a similar shape while keeping the angle between the adjacent lines L constant.

As described above, according to the mixing ratio changing method shown in FIG. 6, by moving any index point P, it is possible to move all other index points P at the same ratio. The operation load can be greatly reduced. In addition, with the mixing ratio of each video signal kept constant (without changing the video content), the output screen (mixing ratio display section Dm (see Fig. 2 etc.) monitor 30 (see Fig. 1)) By changing only the brightness of the image, it is possible to realize the video expression when.

Note that the movement of the line L shown in FIG. 5 can be applied to the mixing ratio changing method shown in FIG. In this case, only the index point Pa and index point Pb at both ends of the line L can be moved by moving the line L in parallel (or by configuring the line L so that only translation is possible). In addition, the index point Pc and the index point Pd can be moved at the same rate.

[0063] Next, the mixing ratio changing method shown in FIG. 7 will be described. Here, the cross-fade of two video signals corresponding to two coordinate axes Z arranged on a straight line (the effect of fading out one video and fading in the other video, gradually connecting the video) Show how to achieve FIG. 7 (a) shows a radar chart 29 when the video signals A, B, and D are mixed at a mixing ratio of 100% and the video signal C is mixed at a mixing ratio of 50%. When the index point Pa is moved to the dotted line side (minus side) from the state shown in the figure, the other index points Pc existing on the same straight line are moved to the plus side at the same rate. be able to. That is, a predetermined amount of an arbitrary index point Pa is set so that the sum of the mixing ratios of all video signals does not change (so that the sum of the mixing ratios indicated by two index points P existing on the same line does not change). With another movement (100% → 50%), it is possible to move another index point Pc on the same straight line by a predetermined amount (50% → 100%) to the opposite side of plus Z minus. .

[0064] As described above, according to the mixing ratio changing method shown in FIG. By arranging the coordinate axes Z of each video signal so that they are located on a straight line, it is possible to realize a cross-fade of two videos.

[0065] In the above example, the movement of an arbitrary index point P and the movement direction of another index point P existing on the same straight line are assumed to be opposite to plus Z minus. It is okay. That is, from the state of (a) in the figure, the index point Pc is moved by 50% (50% → 0%) with the movement of any index point Pa minus 50% (100% → 50%). Is also possible. However, in this case, the total mixing ratio of all video signals before the change and the total mixing ratio of all video signals after the change will change.

[0066] Further, with the movement of an arbitrary index point P, the user can set whether to move another index point P existing on the same straight line in the same direction or in the opposite direction. May be configured.

Further, the movement of the line L shown in FIG. 5 can be applied to the mixing ratio changing method shown in FIG. That is, for example, when the line Lab is moved, as shown in FIG. 7, when the index point Pa is moved from 100% to 50% and the index point Pb is moved from 100% to 100% (the index point Pb does not move). ), The index point Pc existing on the same line as the index point Pa is changed from 50% → 100% (or 50% → 0%), and the index point Pd existing on the same line as the index point Pb is changed to 100 It can be moved from% to 100% (Pd is immobile).

[0068] It is the same whether the index point P or the line L is moved. However, as the index point P moves, another index point P existing on the same line is moved. If it cannot be moved, the other index point P is fixed. That is, for example, as shown in FIG. 7 (a), the index point Pd is changed from the state in which the index point Pb and the index point Pd indicate the mixing ratio of 100% to the minus side of the index point Pb. When moving to the opposite side (plus side), it is not possible to move further from 100% to the plus side. In this case, the index point Pd remains stationary (it remains at 100%).

[0069] Next, the mixing ratio changing method shown in FIG. 8 will be described. Here, a method for realizing crossfading when the video signal to be crossfade is 1: m (where m≥2 is an integer) is shown. Fig. 8 (a) shows the radar chart 29 when mixing video signal A at 100%, video signals B and D at 70%, and video signal C at a mixing ratio of 50%. It is. In addition, the case where the index point Pb and the index point Pd are designated to automatically move with the movement of an arbitrary index point P (indicated by a circle circled on the target index point). (Target index point designation means) The target index point can be specified by any method, such as pressing the index point P twice in succession (double-clicking) or pressing the corresponding video display section Da to Dd (see Fig. 2 etc.).

[0070] If the index point Pa is moved 60% (100% → 40%) to the dotted line side (minus side) from the state of FIG. 8 (a), the index that is the target index point will accompany the movement. Point Pb and index point Pd can each be moved 30% to the plus side (70% → 100%). In other words, the total mixing ratio of all video signals before and after the change does not change with the movement of the arbitrary index point Pa (in the example of Fig. 8, the total remains 290%). The index point Pb and the index point Pd, which are target index points, can be moved. In this case, since two target index points are specified, the movement will move by 30% in increments of minus 60%. However, if there are three target index points, it will move by plus 20%. If there is one target index point, it will move 60%. That is, the movement amount of the target index point is a value obtained by dividing “the movement amount of the main index point to be moved” by “the number of target index points”.

Thus, according to the mixing ratio changing method shown in FIG. 8, for example, when an arbitrary index point corresponds to the video signal of the telop display and the target index point is a video other than the telop, Crossfading between the display and other images can be realized. In other words, while fading in one video and fading out, other video can be faded in and faded in, facilitating operability.

[0072] Also in this example, the movement of an arbitrary index point P and the movement direction of the target index point may be the same direction. That is, from the state of (a), the index point Pb and the index point Pd are shifted by 30% (70%) as the index point Pa moves minus 60% (100% → 40%). (→ 40%). Also in this case, the movement amount of the target index point is obtained by “the movement amount of the main index point to be moved Z the number of target index points”. In this case, however, the total mixing ratio of each video signal will change before and after the change. [0073] Also in this example, the user can set whether to move the target index point in the same direction or in the opposite direction as the arbitrary index point P moves. good.

[0074] In addition, a combination of the main index point and the target index point may be set! That is, when the main index point Pa and the target index point Pb, and the main index point Pc and the target index point Pd are combined, the target index point Pb moves as the index point Pa moves. The target index point Pd does not move. Similarly, the target index point Pd moves as the index point Pc moves, but the target index point Pb does not move.

[0075] Further, it may be configured such that the user can set whether or not the specified target index point can be moved. However, if the target index point is set so that it can be moved, other index points will not move as the target index point moves.

[0076] In addition, if it is configured to be set as a combination of a main index point and a related index point that is not a combination of the target index point, the other index point can be moved along with the movement of either one Is also possible. In other words, if the index point Pa and the index point Pc are set as a combination of related index points, the index point Pc is moved along with the movement of the index point Pa, as in the example shown in FIG. It is possible to move the index point Pa with the movement of Pc.

[0077] Next, the mixing ratio changing method shown in FIG. 9 will be described. Here, we show how to move the target index point by the same amount as the main index point. Fig. 9 (a) shows the radar chart 29 when video signals A to D are mixed at a mixing ratio of 50% for V and deviation. Moreover, the case where the target index point is designated as index point Pb and index point Pd is shown.

[0078] From the state of Fig. 9 (a), when the index point Pa is moved 50% (50% → 100%) to the dotted line side (plus side), the index point that is the target index point is moved accordingly. Pb and index point Pd can also be moved by 50% (50% → 100%) respectively. That is, the target index point can be moved with the same movement amount as the arbitrary index point Pa moves. Therefore, when there are three target index points other than Pa, the radar chart 29 is deformed in a similar manner as in the example shown in FIG.

[0079] Thus, according to the mixing ratio changing method shown in FIG. 9, the main index point P is moved. The target index point can be moved by the same amount. Therefore, by designating target index points according to the relevance of video, it is possible to realize effective video expression and reduce the operation load.

[0080] Even in this example, various modifications are possible as described in the above examples.

As described above, in FIGS. 4 to 9, several examples of the mixing ratio changing method have been described. However, it is possible to combine the examples and to specify the changing method by mode setting or the like. Also, the arrangement of the coordinate axis Z may be asymmetry, which is not necessarily symmetrical as in the above example.

[0082] The number of input video signals is not limited to four, and may be plural. For example, Fig. 10 (a) shows a radar chart that is displayed when two video signals A and B are input and the mixing ratios are all set to 100%. . When two video signals A and B are input, if the coordinate axes Za and Zb are arranged on a straight line, the line Lab cannot be displayed. Therefore, it is preferable that the coordinate axes Za and Zb are orthogonal to each other as shown in FIG.

[0083] Fig. 10 (b) shows a radar chart that is displayed when eight video signals A to H are input and the mixing ratio is set to 100%. Is. Thus, when there are a large number of input video signals, the radar chart is preferably expressed in a well-balanced polygon (a regular octagon when the number of video signals is eight).

As described above, according to the video signal processing system SY video signal processing device 20 and the touch panel integrated display device 21 according to the present embodiment, the radar having a polygonal force corresponding to the number of input video signals. Chart 29 shows the mixing ratio of each video signal and the mixed state of a plurality of video signals mixed based on them. In addition, a commonly used deformation (shape and area) of the radar chart 29 can indicate the mixed state of multiple video signals. Can be shown. Even when there are many video signals to be mixed, it is only necessary to increase the number of coordinate axes Z and index points P displayed on the touch panel integrated display device 21 (no need to increase the display space), thus saving space. Can be achieved. Moreover, the touch panel integrated display device 21 has not only a function as the display means 27 but also a function as the mixing ratio changing means 26, so that further space saving is achieved. It can be done.

[0085] Further, in the vicinity of the end opposite to the origin O of each coordinate axis Z (position indicating the mixing ratio 100%), the video of each video signal corresponding to each coordinate axis Z is displayed on each video signal display unit Da ~. Since it is displayed on Dd (see Fig. 2 etc.), the user can check the video that is the target of operation (the target of changing the mixing ratio), and the operability can be improved. Furthermore, on the same touch panel integrated display device 21, the video of the mixed video signal mixed with each video signal is displayed on the mixed video display Dm (see Fig. 2 etc.), making it easy to check the video to be output. It is.

Further, according to the mixing ratio changing method shown in FIG. 5, by moving the position of the line L connecting the index points P, the positions of the two index points P located at both ends thereof are moved simultaneously. Because it can be used, operability is good.

[0087] In addition, according to the mixing ratio changing method shown in FIG. 6, as the index chart P is moved, all other index points so that the radar chart 29 expands and contracts in a similar shape. Since the position of P can be moved, it is possible to change only the luminance ratio (brightness impression) while keeping the mixing ratio of multiple video signals constant.

[0088] Further, according to the mixing ratio changing method shown in FIG. 7, when two coordinate axes (in the example of FIG. 7, coordinate axis Za and coordinate axis Zc) are arranged on a straight line, an arbitrary index is set. The position of the index point P on the same straight line as the index point P can be moved so that the total mixing ratio of each video signal (all video signals) does not change as the position P moves. By arranging two related videos so that the coordinate axis Z of each video signal is positioned on a straight line, crossfading of the two videos can be realized.

Further, according to the mixing ratio changing method shown in FIG. 8, by specifying a target index point to be automatically moved among a plurality of index points P, the position of any index point P can be changed. Therefore, the position of the target index point can be moved so that the total mixing ratio of each video signal does not change, so the related video has a relationship of l: m (where m≥2 is an integer) Even in this case, it is possible to realize crossfading between one video and other video.

Further, according to the mixing ratio changing method shown in FIG. 9, by specifying a target index point to be automatically moved among a plurality of index points P, the position of an arbitrary index point P is set to a predetermined amount. When moved, the position of the target index point is also increased by a predetermined amount along with the movement. Can be moved to the minus side, so only one main video signal operation is required.

The mixing ratio of other video signals can be changed by the same amount, and the operability is good.

[0091] In the above-described embodiment, when the video signals are mixed, they are mixed by the feeder method, but may be mixed by the wipe method. For example, in the method of changing the mixing ratio shown in FIG. 7, the force that can realize crossfading of two images corresponding to two coordinate axes Za and Zc arranged on a straight line is mixed by a wipe method. Explain how to do this. As shown in Fig. 11 (a), the video display units Da and Dc display video A and video C as shown, for example, video signal A: 20%, video signal C: 80% When mixed at, mixed video as shown in (b) of the figure is displayed on the mixed video display section Dm. In this state, if the mixing ratio is set to video signal A: 80% and video signal C: 20% by moving (dragging) the index point Pa or the index point Pc, the mixed video display unit Dm Then, a mixed video as shown in FIG. That is, a mixing method (wipe method) that gradually changes from one end of image A to image C according to the mixing ratio may be adopted in the present invention.

[0092] In the above embodiment, the video displayed on each video display unit Da to Dd is always 100% regardless of the set mixing ratio (the position of the index point P on the coordinate axis Z). Although the display is performed with the luminance rate, it may be displayed with the luminance rate according to the mixing ratio of each video signal. According to this configuration, since each video is displayed at a luminance rate corresponding to the mixing ratio of each video signal, the user can check what video each video signal is mixed. However, if the mixing ratio is set to 0%, nothing will be displayed on each video display section, so if the mixing ratio is set to 10% or less, it will be displayed at a luminance rate of 10%. It is preferable to provide a display luminance rate limit.

[0093] In the above embodiment, the minimum value and maximum value of the force assuming that the minimum value of each coordinate axis Z is set to 0% and the maximum value is set to 100% can be arbitrarily set. . Further, a minimum value and a maximum value may be designated for each user force coordinate axis z. According to this configuration, the range of video expression is expanded, and it is possible to obtain a processing result according to the user's preference.

[0094] In the above embodiment, the radar chart 29 in which the index points P are connected by the line L is displayed. Force to do It is not always necessary to display line L. In other words, only the position of each index point P on each coordinate axis Z may indicate the mixed state of each video signal.

In the above embodiment, a force-mechanical fader that uses the touch panel integrated display device 21 to change the mixing ratio of each video signal may be used. In other words, the mixing ratio of each video signal may be changed by the knob (gripping part) of each feeder. However, in this case, the normal-shaped knob (side grip) is difficult to operate because the movement direction differs for each feeder. Therefore, it is preferable to devise a knob shape so that it can be slid by pressing with a finger from above. According to this configuration, since the fader can be operated without changing the direction of the wrist one by one, the operability is good. Note that the knob shape can be devised by increasing the area of the knob upper surface (to enable pressing from the top), denting the center of the knob upper surface, providing a non-slip, and sliding when pushed to release the lock. And so on.

Further, in the above embodiment, a VJ device is cited as an example of the video signal processing device 20. The present invention can be applied to a DVJ device (disc jockey (DJ) that can handle an audio signal and a video signal as an instrument. The present invention may also be applied to devices that combine DJ equipment and VJ equipment used for performance. That is, in the video signal processing device 20 of the present embodiment, the video signal subjected to the video effect in synchronization with the audio signal may be mixed. According to this configuration, more various video expressions can be realized.

[0097] In addition to the VJ device and DVJ device, the video signal processing device 20 is a device or program (video mixer, video controller, video processing application) that can input a plurality of video signals and blend them. Etc.), the present invention is applicable.

In addition, each unit and each function in the video signal processing device 20 shown in the above example can be provided as a program. It is also possible to provide the program stored in a recording medium (not shown). Recording media include CD-ROM, flash ROM, memory card (compact flash (registered trademark), smart media, memory stick, etc.), compact disc, magneto-optical disc, digital versatile disc, flexible disc and node disc. Etc. can be used.

[0099] The system configuration and video signal of the video signal processing system SY are not limited to the above-described embodiments. The device configuration, operation method, and the like of the signal processing device 20 and the touch panel integrated display device 21 can be appropriately changed without departing from the gist of the present invention.
