DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an editing controller capable of visually and easily setting an effect color used when editing a video.

[0002]

2. Description of the Related Art In a video editing operation, various editing effects are applied. In order to perform editing work, a video device such as a VTR, a switcher that executes editing effects, and a VTR
And an editing controller that controls the switcher and executes and controls the entire editing work.

[0003] FIG. 3 is a configuration diagram showing a connection relationship between devices at the time of editing. 30 is a player V for reproducing the source video
TR, 31 are a player VTR for reproducing the other source video, and 32 are a player VTR 30 and a player VT.
A switcher 33 for applying an editing effect to the video signal output from the R31 and outputting the video signal; 33, a recorder VTR for recording the video signal edited by the switcher 32; 34, a television monitor for displaying effect colors and confirming the editing effect; 35 is a player VTR30 / player VTR31 /
This is a conventional editing controller that controls the switcher 32 / recorder VTR 33 using RS422 communication. The TV monitor 34 includes not only the switcher 32 but also two TV monitors including the switcher 32 and the recorder VTR3.
3 may be connected to both. In FIG. 3, the solid line is the flow of the video signal, and the dotted line is the RS422 control line centered on the editing controller 35.

In the switcher 32, the player VT
An editing effect is applied to the reproduced video output of the R30 and the player VTR 31.
One that gradually switches the player VTR images (for example, switching from the left side of the image of the player VTR 30 so that the image of the player VTR 31 overlaps),
There are various types such as adding a digital effect to the video output of one VTR like mosaic processing. Further, the switcher 32 has an effect color called a matte (MATTE) color. For example, in the case of a wipe effect or the like, a border line using a matte color color called a border line is provided at a boundary where images from two players are switched. It is possible to perform a process of inserting or replacing a specific part of a video with its color.

[0005] Therefore, the switcher 32 has a function of setting the matte color, and the setting can be changed usually by a communication command from the editing controller 35.

In the conventional editing controller 35,
While looking at the television monitor 34 on which the edited video is actually displayed, the brightness of the matte color (also referred to as brightness / color brightness), saturation (also referred to as color saturation / color saturation), hue (hue) (Also referred to as "volume").

[0007]

However, in the above-described conventional configuration, the effect color is set while watching the television monitor on which the edited video is displayed. There has been a problem that the color setting becomes subjective and it is difficult to perform absolute color management, for example, the color may not be as expected.
In addition, there is also a problem that it is difficult to reproduce the previously used effect color again due to individual differences and subjective differences. In particular, in the case of the hue setting, unlike the brightness and the saturation, the size is not set, but the angle is set from 0 to 360 degrees. Therefore, it is not known what color each angle corresponds to. Had the problem of being difficult.

In addition, the operability is not good, for example, since it is necessary to look at a television monitor distant from the place where the editing controller is operated, so that it is necessary to operate at hand while looking far away.

An object of the present invention is to solve the above-mentioned problems and to make it possible to perform absolute value management of the effect color setting performed while watching a television monitor, and also to make it easy and operable visually. .

[0010]

According to the present invention, there is provided an editing controller having a built-in switcher function or capable of controlling an external switcher, comprising a color display and an editing effect color setting value input means. The editing effect color setting value input means is operated and the effect color used for editing is set while checking the display on the color display.

[0011] This makes it possible to objectively and efficiently set the effect color without being affected by the background image, while looking at the color display with the built-in editing controller near the operation unit instead of the TV monitor on which the image is displayed. Becomes possible.

Further, according to the present invention, in the display of the color display according to the present invention, the color can be easily set by displaying the set numerical value and the graphic display together.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention relates to an editing controller which has a built-in switcher function or can control an external switcher.

According to a second aspect of the present invention, for the brightness setting and the saturation setting, a graph representing the set value is displayed on the color display together with the set value, and the value is set by operating the edit effect color set value input means. And the size of the graph changes with the change of the value. This has an effect that the effect color can be absolutely set by using a numerical value, and that it can be set visually and easily.

According to a third aspect of the present invention, in the hue setting, a color graph displaying the entire hue together with a set numerical value and a mark indicating a specific position in the color graph are displayed on a color display, and an editing effect color is displayed. The setting value input means operates to change the numerical value and display the setting color position on the color graph with a mark, so that the effect color can be absolutely set using the numerical value, and the overall color arrangement can be changed. Since the optimum hue angle can be selected while grasping, it is possible to easily and easily set visually.

According to a fourth aspect of the present invention, there is provided means for storing and recalling a set value relating to a color, and has an effect that a previously set color set value can be easily reused. Have.

Hereinafter, embodiments of the present invention will be described. FIG. 1 is a configuration diagram showing a connection relationship between devices at the time of editing. Reference numeral 10 denotes a player VTR for reproducing a source video, and 1
1 is a player VTR for reproducing the other source video,
Reference numeral 12 denotes a switcher for applying and outputting an editing effect to video signals output from the player VTR 10 and the player VTR 11, reference numeral 13 a recorder VTR for recording the video signal edited by the switcher 12, reference numeral 14 a television monitor for confirming the editing effect, 15 is a player VTR 10
/ Player VTR11 / Switcher 12 / Recorder V
An edit controller for controlling the TR 13 using RS422 communication, 20 is a liquid crystal color display mounted on the edit controller 15, and 17 is three volumes as edit effect color setting value input means for setting brightness, saturation, and hue. is there.

The television monitor 14 is connected to the switcher 1
Not only two but two TV monitors are switcher 12
And the recorder VTR 13 in some cases.
In FIG. 1, the solid line is the flow of the video signal, and the dotted line is the RS422 control line centered on the editing controller 15.

The functions of the devices other than the editing controller 15 are the same as those of the conventional example shown in FIG. The setting of the matte color in the configuration of FIG. 1 is performed by displaying the setting screen on the liquid crystal color display 20 mounted on the editing controller 15 instead of the TV monitor 14 as in the related art. FIG. 2 shows an example of a color setting screen on the liquid crystal color display 20. In FIG. 2, reference numeral 20 denotes a liquid crystal color display displaying a color setting screen, reference numeral 21 denotes a brightness setting display unit including a setting value and a graph, reference numeral 22 denotes a saturation setting display unit including a setting value and a graph in the same manner as 21, and reference numeral 23 denotes a saturation setting display unit. A hue setting display section comprising a set value and a color graph, 24 is a save button for saving the set value, and 25 is a call button for calling the previously saved set value.

When the liquid crystal color display 20 is compatible with a touch panel, the save button 24 and the recall button 25 can be operated by directly touching the liquid crystal color display 20; May be provided.

The setting of the matte color will be described with reference to FIG. First, regarding the brightness setting, since the magnitude of the brightness is set, the size is set using the volume 17.
By turning one of the volumes 17, the numerical value display of the brightness setting display section 21 of the liquid crystal color display 20 becomes 0%.
The size of the graph changes as it changes between １００100%. Similarly, turning the volume 17 of the saturation setting display section 22 changes the numerical display between 0% and 100% and changes the size of the graph.

However, since the hue is the phase of the color, it is difficult to represent it by the size of the graph. Hue from 0 degrees to 360
The angle gradually changes from blue to magenta to red to yellow to green to cyan to blue. For this reason, it is necessary to actually set the hue while viewing the entire color sample in order to improve operability. In view of this, the hue setting display section 23 displays the phase angle by a number and also displays in advance a color graph showing the state of the overall color change. The color graph displays colors corresponding to angles from 0 to 360 degrees in a gradual manner.
A triangle below the color graph is a mark indicating the current setting value position in the color graph (in FIG. 2, it indicates 210 degrees indicated by the setting value). By doing so, in the hue setting, the entire color change can be grasped, and the current setting can be easily known. On the other hand, in a configuration in which only the color indicated by the set value is displayed, it is not easy to know what other colors are available and which direction the volume can be turned to set the target color.

In the above-described embodiment, the hue setting is such that the color graph is displayed at a fixed angle of 0 to 360 degrees and the triangular mark is moved by the volume setting. A configuration in which the graph moves left and right in a loop by volume setting may be used.

The graphs in the lightness setting display section 21 and the saturation setting display section 22 are fixed colors, but the specification may be such that the colors of the graph change according to the colors set in the hue setting display section 23.

[0025]

As described above, according to the present invention, only the effect colors can be objectively examined without being influenced by the background image while watching the color display built in the editing controller instead of the television monitor on which the background image is displayed. It is possible to obtain a great effect that the color can be easily set by using the absolute value by a numerical value.

Further, since the editing effect color setting value input means and the color display are at the same hand, there is an effect that the editing efficiency is increased.

Furthermore, since the set values relating to the colors can be stored and recalled, there is an effect that the previously set color set values can be easily reused.
