Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sorting device suitable for, for example, a video special effects device that combines a plurality of television images to generate one television image.

Examples of such video special effects include wipes and montages.

A video special effects device that obtains such special effects will be described. In FIG. 1, S,, S2, S3, .

Here, the main special effects will be explained with reference to FIG. 2, illustrating, for example, a case where a floor image and a bright image are combined.

That is, A is a composite screen of a fat image a appearing from the upper left and a bright image b of another section, and the part of the fat image a expands in the direction of the arrow with time, and finally becomes the clear image a. A special effect is displayed in which a portion occupies the entire area.

In addition, B, C, and D have the same effect as A, but the enlargement direction of the fat image a is different by 900 degrees as shown in the figure.

Further, E and F indicate a special effect in which the floor image portion a appearing from the left or above gradually expands in the direction of the arrow.

The above special effects A to F are all changes in the linear direction, but G to J are visual effects in which the floor image portion a expands in the circumferential direction like an arrow, and G to J are simply changes. The lengths are different for women.

Further, K, the current floor image portion a initially occupies both left and right ends or both upper and lower ends, and these floor image portions a move in the direction of the arrow. Among the various video special effects described above, if you want to obtain the video special effect shown in FIG. 2 E, for example, switch S, which corresponds to the desired special effect among the switches shown in FIG. Close the circuit. When this switch S is closed, the DC power supply DC voltage is supplied to the circuit corresponding to the switch S of the fundamental wave selection device 11. This fundamental wave selection device I1 selects the output waveforms of the horizontal fundamental wave generator 12 and the vertical fundamental wave generator 13 so as to obtain a special effect corresponding to a closed switch, for example, switch S. . The horizontal fundamental wave generator 12 is configured to be able to generate, for example, a triangular wave, a sawtooth wave, a parabolic wave, or a high frequency wave thereof having a repeating period of one horizontal scanning period of a television image, and the fundamental wave selection Under the control of the device 11, a fundamental wave having a waveform that provides the desired special effect is derived.

Further, the vertical fundamental wave generator 13 is configured to generate, for example, one of the television images.
Triangular waves and key-tooth waves with a repeating period of vertical scanning period,
It generates a parabolic wave or the like, and similarly to the horizontal fundamental wave generator 12, it derives a fundamental wave with a waveform that matches a required special effect under the control of the fundamental wave selection device 11.

The horizontal fundamental wave and the vertical fundamental wave derived from the horizontal and vertical fundamental wave generators 12 and 13 are sent to the slice circuit 1, respectively.
4.15 and sliced at a preset level.

The respective fundamental waves sliced by the slicing circuits 14 and 15 are combined by a combining circuit 16 and converted into a key signal for generating a combined video signal. Note that the key signal can also be generated by combining the horizontal fundamental wave and the vertical fundamental wave in the mixing circuit M, and then slicing them in the slicing circuit 14.

The key signal generated in the manner described above is applied to the switching mixing amplifier 17, which controls, for example, the bet image signal V and the bright image signal V2, and outputs a fat image and a bright image to the output device. A composite image signal to which a special effect has been added such that the images are composited is outputted to the output terminal 0.

As described above, in a video special effects device, one special effect corresponds to one switch, so as the types of special effects increase, the number of switches also increases. Therefore, there is a drawback that the control board on which these switches are provided also becomes large.

In order to solve the problem of the large size of a single control board, switches for frequently used video special effects are arranged on the main control board, while switches corresponding to less frequently used video special effects are arranged on the main control board. Switch Sn. ... A configuration has been proposed in which Sn2 is arranged on the auxiliary control board 18 as shown in FIG.

Each switch Sn.・・・
. . . Among the video special effects corresponding to Sn2, for example, when it is desired to obtain a special effect as shown in FIG. 2K, the switch Sn is closed in advance.

Next, when obtaining the special effect, the auxiliary switch Sn on the main control board 19 is closed, and the DC voltage is applied to the fundamental wave selection device 1 via the switch Sn on the auxiliary control board 18.
1 to realize the special effect image.
According to the above configuration, switches corresponding to special effects that are used less frequently can be arranged on the auxiliary control board, so that the number of switches arranged on the hand control slope that is frequently operated by the operator can be reduced.

Therefore, although the shape of the main control board can be made smaller, since one switch corresponds to one special effect, the overall size of the control board cannot be avoided.

Furthermore, in order to reduce the structure of the control board, insertion holes 221, 222, 223 are provided on the control board 21 as shown in FIG. There is a method of inserting such a block 23 to obtain a desired special effect.

That is, several blocks corresponding to the required types of special effects are prepared in advance, and the blocks corresponding to the special effects actually used in one program are inserted into the insertion holes on the control board 21.
For example, this block is placed in 222 and is controlled when obtaining special effects.

According to this method, each block can be replaced, so that only the blocks corresponding to the required special effects need be inserted into the control board, and the shape of the control board can be made smaller.

However, even in this method, one sorting device is required for each special effect, so as the number of types of special effects increases, the number of sorting devices also increases accordingly.

The present invention solves the above-mentioned drawbacks and is suitable for, for example, video special effects equipment, for example, the shape of the control board can be reduced,
Furthermore, the present invention provides a sorting device that can reduce the number of blocks for special effect operations.

An embodiment of the present invention will be described below with reference to FIG.

41 is a cylindrical block, the upper cover 42 is made of a material that transmits light, and a pattern 43 as shown in FIG. 2A, for example, is displayed on its upper surface.

The inside is a hollow portion 44 having a square cross section, for example. Therefore, the four side surfaces around the block 41 are thin cylindrical walls 45. these four walls 45
A through hole 46 is formed in one of the walls as identification information corresponding to a special effect, for example. These through holes 46 are
The position is appropriately selected so as to have a corresponding relationship with the type of special effect. Therefore, there is a one-to-one relationship between the combination of positions where the through holes 46 are formed and the type of special effect. In addition, the other walls of the block 41 are formed with a different arrangement of through holes from the arrangement of the holes in the wall to correspond to other special effects.

On the other hand, 47 is a board, and a base 48 is supported by spring pieces 49 on this board 47.

The base 48 is formed with an insertion hole 50 into which the wall 45 of the block 41 is inserted. The base 48 also has a protruding portion 5 that fits into the hollow portion 44 of the block 41.
1 is provided, and a lamp 52 is placed at the end of this protrusion 51 as a light source.

When the block 41 configured as described above is pressed downward, the magnet 53 on the bottom surface of the block 41 approaches the magnetic switch 54,
Magnetic switch 54 is activated.

As a result, control circuit 55 enters the active state. Due to the action of this control circuit 55, the lamp 52 is turned on, and the block 41
The pattern 43 on the top surface is irradiated from inside to clearly indicate the block in the operating state. On the other hand, a plurality of light emitting diodes 56 for detecting identification information are also turned on, and their light rays are incident on a forward diode 57 through a through hole 46 formed in a side wall 45 of the block 41. Note that the through holes provided in the side walls of one of the blocks are provided at positions corresponding to the types of special effects as described above, so that the photodiode's hole in each wall depends on which light beam has arrived. The attached identification information can be read.

Furthermore, if the block 41 arranged as described above is rotated, for example, 90 degrees to the right, the pattern on the top surface of the block will be oriented as shown in FIG. 2B.

In this positional relationship, the light emitting diode 57
As the cylindrical block 41 rotates, another adjacent wall will be located between them. A through hole is formed in this wall at a position corresponding to the special effect shown in Figure 2B.
This information will be read. In the example described above, the control circuit 55 is activated by pressing the block 41 downward, but for example, as shown in the figure, the control circuit 55 can be activated by pressing the push button 58 provided near the block. , the control circuit 55 may be operated.

If it is difficult to express one piece of identification information with only one side wall due to restrictions on the size of each block, for example, two sides facing each other or three predetermined sides may be used. It is also possible to attach one piece of identification information.

In addition, the above-mentioned blocks have all been explained in the case where special effects are obtained in one block, where the patterns on the special effect screen are the same, but only the orientation is different.
It is also possible to obtain special effects with one block, even if the design itself is different. FIG. 5 is a diagram illustrating a state in which the blocks having the above-mentioned configuration are assembled into a control board. 311
, 312, 313 are blocks, 32 is a control plate, and each block 311, 312, 313 is inserted into an insertion hole 331, 332, 333 formed in the control plate 32.

As described above, each insertion hole 331, 332,
To obtain a special effect as shown in FIG. 2A with the blocks 311, 312, and 313 inserted into the block 333, for example, the block 311 is pressed downward.

This pressing activates the control circuit 36 as described above, and the identification information of the block 311 detected by the detection element 351 such as a photodiode is supplied to the fundamental wave selection device 11 via the control circuit 36. On the other hand, the fundamental wave selection device 11 controls the horizontal fundamental wave generator 12 and the vertical fundamental wave generator 13 so as to obtain a special effect corresponding to the identification information sent from the control circuit 36, as explained in FIG. It is possible to select the fundamental wave generated from each generator 12, 13, and adder M and synthesis circuit 16 as will be explained later.
It controls the

That is, the horizontal fundamental wave generator 12 generates, for example, a triangular wave or a sawtooth wave whose repetition period is one horizontal scanning period, and the vertical fundamental wave generator 13 generates a triangular wave or a sawtooth wave whose repetition period is one vertical scanning period. This generates chain tooth waves, etc.

The operations below the fundamental wave selection device 11 are the same as those shown in FIG. 1, so the same parts as in FIG. 1 are given the same numbers and their explanation will be omitted. As described above, the present invention uses blocks with multiple types of identification information attached to their sides, so when applied to a video special effects device, for example, one block can be easily connected to each other by simply changing its orientation. Since a plurality of different special effects can be set, the number of control blocks to be prepared in advance can be significantly reduced.

As explained above, the sorting device of the present invention has the advantage that, for example, it is possible to reduce the number of necessary blocks that are suitable for use in video special effects bags, and that the shape of the control board can also be made smaller.

In addition, each block is removable, so the block is removable.

The racks can be arranged freely, and the arrangement can be convenient for the operator who operates the control board.
