Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote control device for remotely controlling a controlled device, such as a television camera, which is placed apart from a console, and sequentially controlling the device to a desired setting mode.

Conventionally, various devices have been known that are remotely controlled based on operation signals from an operation console. However, when a controlled device is remotely controlled in advance into multiple desired modes, the operation console has a control panel that is configured to have a control panel that corresponds to each mode. In most cases, a large number of potentiometers and the like are used and preset, and each potentiometer is sequentially selected and used as a remote control signal during remote control.

Since the potentiometer itself is inherently high resolution,
Although the signal accuracy of the control signal itself is good, if there are many desired settings to be made, a number of potentiometers will be required for each setting, and even more so, multiple potentiometers will be required to specify each setting. In such cases, the number of potentiometers increases dramatically, making it difficult to configure the potentiometers on the console side and each setting mode, which is the main cause of lower operability. Yet another drawback of conventional remote control devices using such potentiometers is that when the conditions set for each aspect are modified, the preset settings are lost, and it is difficult to restore the settings. This is something that cannot be done. A case of a remote control device for a television camera to which such a known remote control device is applied will be specifically explained. Normally, the six main control elements of a television camera are panning, telemetry, zooming, focusing, aperture D (iris), and camera height. Therefore, when operating the camera from a console that is separate from the TV camera, these different types of control signals are sent from the console, and the potentiometer is adjusted while watching the monitor on the console. Each control element of the television camera is adjusted so that the monitor image becomes a predetermined image, and the television camera is adjusted to a desired setting mode. If there are multiple settings, further adjust the other potentiometers, and while monitoring the TV camera's imaging situation, send a control signal to the camera's control element, and adjust the potentiometer. Set the group. After completing such a setting operation, when sequentially selecting camera images (hereinafter referred to as shots) based on the setting mode of each television camera, each potentiometer group is sequentially selected. In other words, the above-mentioned conventional device mechanically stores the setting mode of the television camera by the amount of adjustment of the potentiometer.
The television camera is remotely controlled based on this storage amount. Therefore, as the number of setting modes and control elements that define each mode increases, the number of potentiometers increases accordingly.1) The area occupied by the potentiometer knob on the console increases, resulting in an increase in the number of shots. do not have.

2. Since a large number of potentiometers are listed on the operation console, it is unclear which knob corresponds to the control element of the television camera, and operability is poor.

3. Since each control element is independently and remotely operated by a potentiometer, each control element is driven independently, resulting in an extremely unsightly captured image.

4 After adjusting the potentiometer, if it is readjusted for correction, the original setting position will be lost and it will not be possible to reproduce the shot with the original setting mode again.

5. Since it is controlled by analog signals, it is impossible to link with an external computer.

? Since it becomes unclear which shot is the shot that was being regenerated when the power supply was stopped due to a power outage or failure of the operating power supply, it is necessary to search for the desired shot by resetting the start setting mode.

and various other runners-up. The purpose of the present invention is to
This device attempts to solve the above-mentioned drawbacks of the conventional remote control device, and its feature is that it generates an amount of electricity corresponding to the setting state of each cut of the controlled member of the camera, such as aperture, focus state, etc. A storage circuit having a plurality of storage sections storing data for each cut (Example, MS in FIG. 3B)
corresponds to

), a stepping circuit (corresponding to 406 in FIG. 3C in the embodiment) that sequentially steps through the contents when driving the controlled member of the camera for each cut; Selection for selectively selecting a predetermined storage section and transmitting the amount of electricity in the selected storage section to a drive circuit of the controlled member to drive the controlled member based on the amount of electricity in the selected storage section. Circuit (Example, corresponds to 416, 452 in Figure 3C)
The controlled member is sequentially driven to the set state for each cut, and is connected to the stepping circuit to step in accordance with the stepping operation of the stepping circuit, and to adjust the contents of the stepping circuit. an electro-mechanical step switch (embodiment, corresponding to 609 in FIG. 3D) indicating the step state according to the step; and a transfer circuit (corresponding to 609 in FIG. 3D) for transferring the step state of the switch to the step circuit upon restart. (corresponding to 614 in FIG. 3D) is provided, and after an interruption due to a power cut, etc. during driving of the controlled member for each cut to the set state, upon restart, the contents of the step-by-step circuit are changed at the time of interruption. The present invention resides in that the setting state of the controlled member at the time of restarting the device is reproduced by returning to the stepping state. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a case in which a specific embodiment of the present invention is applied to a remote control device for a television camera will be described with reference to the drawings.

In this case, the yellow lamp in the button corresponding to the shot position to be read out next among the information sequentially read out by operating the change button described later is constructed so as to light up. 9 is a cut memory button. When the presetting operation for each shot is completed by operating the shot memory button 5, press this button and press the shot buttons 61 to 61 in the desired order.
When 616 is pressed, the desired shot order is stored in a storage device, which will be described later, together with the time element set by the time setting knob 8.

If the knob 8 is set to AuTO, the shot will be automatically shifted to the next shot at a preset time in the self-memory device. Reference numerals 131 to 1320 indicate display devices which are lit up sequentially to display the next storage section corresponding to the address to be stored in the memory device, which will be described later, when the shot order is stored in the storage device; 141 to 1420, during shot reproduction; A display device for displaying the current reproduction position, 15 a button for clearing the contents of the storage device, 16 a power switch, 18 and 19,

25 is a fine adjustment/coarse adjustment changeover switch, and when the knobs 1 to 4 are turned to change to the fine side, the output signal of the rotary encoder is gradually decreased to change the setting amount widely, and it is used for fine adjustment. It is something.

In addition, each of the above buttons 5, 9, 11, 12, 21, 22

204F outputs A-D are connected to its inputs and are time-divided into each output and sent out from its output 206 in parallel.

20T is a selection circuit that selects each of the counter outputs A to D using a sampling signal from the sampling signal generation circuit 208S, and sequentially selects each of the outputs A to D from D to A.
This is what is sent to the converter 208.

209G to 212G are sample and hold circuits and D-
The analog signal from the A converter 208 is selected by the sampling signal from the sampling signal generation circuit 208s, and each output from each of the counters 201F to 204F is held in each circuit after DA conversion.

Each sample and hold circuit has a comparison circuit 21 at its output.
The 2H and amplification drive circuit 2161 and the servo motor M1 are connected, and each servo motor adjusts the tailing, panning, focusing, and zooming operations of the television camera. Each motor is coupled to a respective potentiometer, which is fed back to the comparator circuit 212H input to insert the adjusted amount of each controlled element into the servo circuit. .

Control elements on the television camera side, ie, tailing, panning, focusing, and zooming, are set in accordance with the setting amounts of knobs 1 to 4. Therefore, the operator, while looking at the monitor 102 on the console side, sets the television camera to a desired mode and enables the camera to take an image of a predetermined shot. Above up/down counters 201F to 204F
has a preset input terminal I, which is connected via an OR gate 220J to a reference position digital signal generator, described below, via a line 2291, while the other input to the OR gate 220J is connected via an AND gate 224K. and is connected to the current location memory of the arithmetic and control circuit section, which will be described later.
Therefore, in the cycle in which the control signal GSB14 is input to the gate 224K, the counter 201F is set to a constant count value by the reference signal from the reference position digital signal generator, and the servo motor M1 for setting the tailing of the camera is set to a predetermined position. is set to The same applies to other control elements, and each counter 202F to 204F
An OR gate and an AND gate circuit (not shown) are connected to the preset input of the circuit and perform similar operations. Arithmetic control circuit configuration (see Figure 3B) This circuit unit allows the television camera to be configured in a desired manner (shot).
Set and store the desired time (cut desired time) for transitioning from one mode to the next mode, and set the set time to a time that allows each control element of the TV camera to move linearly based on this set time during playback. It is provided to change the settings of the camera-side control elements directly.

This necessity is due to the fact that the servo motors M1 (~M4) that drive each control element of the television camera need the maximum speed, that is, the minimum time necessary to adjust each control element, and the control In the case of this embodiment in which the elements are driven and controlled separately and independently, since the adjustment amounts of each control element are different, each control element operates separately, resulting in an image that is extremely difficult to see when captured by a television camera. That's why. In order to eliminate this drawback, this circuit section calculates the set amount of each control element using the maximum speed of the servo motor as a function based on the required cutting time, and calculates the set amount of the cut as necessary. It is used to modify the required time so that each control element is adjusted linearly. In FIG. 3B, 8 is a second illustrated time setting knob, by which the required time for cutting is set, and by rotating the knob,
A time-dependent pulse signal is generated. Note that the time set by the time setting knob is adjusted to a possible integer value that is an integral multiple of the pulse repetition time TO generated from the update pulse generation circuit described later. SWl is a switch that is switched in conjunction with a knob, and is selectively switched between the AutoO position and the M position. These "AutO" and "M" position display indexes are displayed on the knob 8 and are selectively switched in conjunction with the adjustment of the knob. 301 is a timer register, which is controlled by the time setting knob via an AND gate 302. A time coded signal corresponding to the adjusted time is input and temporarily stored.

Reference numeral 303 denotes a time reference value signal generation circuit, which generates a reference timing signal TO.

A multiplication circuit 304 multiplies (n-TO) the output TO of the reference value signal generation circuit 303 inputted to its input AlB by the output n of the timer register 301.

This multiplication result indicates the amount by which each control element is driven in the time code n set by the time setting knob 8 when each servo motor is driven at its maximum speed. Note that the multiplication circuit executes an arithmetic cycle in response to a control signal GSBl8 from a CPU circuit, which will be described later. 305 and 306 are AND gates, and the control signal G from the CPU circuit described later is
Gates are opened by SB2 and GSB3, respectively.

) is transferred, the counted value is temporarily stored. Since the respective count values of the counters 201F to 204F correspond to the amount by which the servo motors M1 to M4 should be driven immediately, each control element on the television camera side is adjusted in accordance with the count values of the counters 201F to 204F. has a defined current location. Destination memory Md transfers information from shot memory 1, which will be described later, to gate 308.
A part of the information stored in the shot memory 1 is temporarily stored in a cycle in which a control signal GSB9 from a CPU circuit, which will be described later, is applied via the CPU circuit. The shot memory will be described in detail later, but when setting the TV camera in the desired mode in advance and setting the shot, the values stored in the counters 201F to 204F necessary for the setting mode are transferred via lines 2061 to 2064. , the control element setting amount required for each setting mode of each shot is stored in advance. Therefore, when the gate 308 is opened and the stored information from the shot memory 1 is stored in the memory Md, the control element settings necessary for the next shot, ie, the destination, are held in the memory Md. Mc indicates an update data memory for holding the calculation results of the calculation circuit described later. A subtraction circuit 309 subtracts information stored in the current location memory Mp and information stored in the destination memory.

Now, set values from the reference position (center) of the control elements on the television camera side, that is, tailing, panning, focusing, and zooming, respectively. f. z, and the current location setting value is Tm. pm. fn]. Zm. If the destination setting values are Tm+1, Pm+1, Fm+1, Zm+1, the subtraction circuit calculates Tm+1-Tm, . pm+1 pm
、． fm+1- Fm,. This is to sequentially calculate Zm+1-Zm. Reference numeral 310 denotes a magnitude determination circuit, which determines whether the output is greater than or equal to the output of the multiplication circuit 304.

ANSI is generated by the determination signal of the determination circuit 310, and when the output of the multiplication circuit 304 is larger than the output of the subtraction circuit 309, it is generated and applied to the CPU circuit, which will be described later, as a control signal GSBl2.
, and starts execution of the arithmetic circuit. In addition,
When the output of the multiplication circuit 304 is smaller than the output of the subtraction circuit 309, the output of the magnitude discrimination circuit 310 is output from the doubling circuit Sh(
Since the processed signal is a digital code signal, it is applied to the up input side of the timer register 301 through the circuit (which consists of a right shift circuit), so the content of the timer register 301 is doubled and the multiplication circuit 304
is input. Subtraction circuit 309 and size discrimination circuit 310
Also, the calculation steps of the calculation circuit 311 are shown in FIG. In Figure 5, the destination is loaded into the destination memory Md (Am+1={ Tm+1, Pm+

After m) is performed, when the voltage is applied to the input of the discrimination circuit 310, since NTO is applied to the other inputs of the discrimination circuit 310, discrimination between the two is started. L is servo motor M

It is repeated until x is reached. This determination time change is sequentially performed for the other control elements P)f)Z as well. Each control element t)P, . f. As a result of the above determination regarding z, the set time n is set for the control element with the largest difference between the destination and the current location.
If there is a time change in , the amount of time change is the maximum, and other control elements are adjusted according to this maximum change time.

As a result of the distance calculation D, the arithmetic circuit 311 calculates the set time n.
, the determination circuit 3 calculates D/n to determine the time update rate and determine to what extent the time change is necessary.
10 causes arithmetic operations to be performed on control elements that require time changes, but since the arithmetic circuit executes the arithmetic operations in binary notation, the arithmetic operations are performed by simply shifting the D signal by R bits. Note that the calculation result is transferred to the update data memory Mc and stored in the memory, but the memory Mc is updated by the calculation output of the calculation circuit 311 when an input signal larger than the stored value is input, and the maximum value among the calculation results is be remembered. 312 is an adder circuit, 313 is an update pulse oscillator,
Reference numeral 314 indicates a large/small discrimination circuit, and the data in the update data memory Mc is transmitted by an update pulse oscillator (period T).
Each time a pulse from O (pulse and oscillation) is generated, it is added to the stored value in the current location memory Mp, and during the cycle period in which the gate 306 is open by the control signal GSB13 from the post-subtraction CPU circuit, the output of the adder circuit 312 is added. is transferred to the current value memory Mp.

Therefore, the contents of the current location memory Mp are updated sequentially, and the current location memory is updated at the updated time every time an update pulse occurs.
Mp increases. This state is shown in the rightmost cycle of the fifth illustrated flowchart. This execution cycle will be explained below with reference to FIG. 5 and FIG. 3B.

In FIG. 3B, the calculation result of the calculation circuit 311 is d=D/
n is stored in the update data memory Mc and is applied to the addition input of the addition circuit 312: arithmetic circuit 311
calculates an updated value, and when the calculation result is given to the adder circuit via the update data memory Mc, the adder circuit 312 updates the current location memory Mp every time a constant periodic pulse from the update pulse oscillator 313 is applied. Update data d is added to the value. When j pulses are input to the adder circuit 312, the cycle at the right end of FIG. 5 is executed j times, and the output of the adder circuit 312 becomes Am+Jd. As a result, the current location register Mp will match the contents of the destination memory Md after a time extended from the time set by the time setting knob 8. During this time, the gates 224K to 227K are open, and each counter 201F to 204F drives each servo motor M1 to M4 according to the contents of the current location register Mp. The determination circuit 314 determines the size of the contents of both memories MnlMd, and when the two match, a match signal A is generated.

The shot memory Ms has a storage capacity of 16 shots, and is formed by rotary encoders 201 to 204 in the address portions of addresses 1 to 16, respectively. The control element settings required to obtain each shot are digitally stored. 316 and 317 are AND gates, respectively, which are opened by control signals from a CPU circuit, which will be described later.

Reference numeral 318 denotes a reference position signal generating section which, when the gate 317 opens in an execution cycle, applies a predetermined number of digital signals to the shot memory Ms, sets all addresses of the memory Ms to predetermined values, and at the same time outputs signals from lines 2291 to 2294.

Each of the above-mentioned memories Mp, . Md. MclMs is a signal PU that clears the memory contents when the device is powered on, as described later.
Since C is applied (not shown), no previous history contents remain at the start of the operation. Setting mode operation control circuit configuration (see Figure 3C) In Figure 3C, 401 and 402 are constant signal generation circuits, 403 and 404 are AND gate circuits, and control signals GCM2 and GRSl from the CPU circuit described later.

413 is a 1 addition circuit, 414 is a 1 subtraction circuit, 415 is an OR gate circuit, and 416 is a cut register for storing a desired shot order.

When you press the cut memory button 9 (Fig. 9),
The gate 403 is opened by the control signal GCM2 from the PU circuit, and the address register 406 is set to "O" by the constant signal generation circuit 401 output.

When any one of the buttons is pressed, the coded signal KSMA corresponding to the number of the pressed shot button is transferred via line 417 to the cut memory 1 via gate 418. At this time, a command signal from address register 406 is applied to cut memory 1 through gate 408 in response to control signal GCM5, and designates the storage address of the encoded signal to be transferred through gate 418 and OR gate 419. As a result, the KSMA signal is stored at address "0" in cut memory 1. At this time, a control signal GSB5 from the CPU circuit, which will be described later, is applied to the gate 420, which opens the gate for the time set by the time setting knob 8. The coded signal n is stored in the cut memory address 1'0' in parallel with the specified number of shots.When this routine is completed, the control signal GSB6 from the CPU circuit is applied to the gate, and the contents of the address register 407 are Transferred to address register 406.

As a result, both registers 406 and 407 are set to the ``1'' state, and the cut memory 416 is instructed that the next storage address is address ``1''. Gate 410 receives control signal GS from the CPU circuit after such a cycle.
B7 opens the address register 40T, adds 1 to the contents of the address register 40T via the 1 addition circuit 413, and returns the register 40? If the contents of the address register 40T are transferred to the 2'' state, the contents of the address register 40T are set to the 2'' state. According to the above routine, the address command signal is generated by the cooperation of both the address registers 406 and 40T, so when the shot button is pressed again, the next possible shot number to be reproduced during playback will be displayed. The time coded signal is stored at the address "1" of the cut memory 1416 together with the coded signal KSMA corresponding to the time coded signal KSMA.

The gate 410 is also opened by the control signal GSB7 from the CPU circuit when the change button 12 or normal skip button 19 in FIG. 1 is pressed, and the above-mentioned routine is performed. 452 are shot numbers sequentially stored in the cut memory 416. Set the command coded signal to a shot address register that temporarily stores the command coded signal, and press the shot buttons 61 to 61.
When 610 is pressed, the control signal GSB from the CPU circuit
The KSMA signal is transferred and stored through the gate 451 opened by I.

In response to a command signal from the shot address register 452 via the line 323, the shot memory Ms causes the stored information in the specified address section stored in the shot memory Ms to be transferred to the destination memory Md by opening the gate 308. After the above routine is completed, the arithmetic operation described in the circuit configuration section described above is executed by the control signal G from the CPU circuit described later.

Reference numerals 603 and 604 indicate write circuits for the magnetic card, and read circuit 605 indicates a control OR gate.

When the write button 23 is pressed, the motor of the card reader section is activated by a control signal G'CR4 from the CPU circuit, which will be described later, and the card 602 is fed and the control signal GC is activated.
The write circuit 603 is activated by R8, and the cut memory 41 is activated via the third C gate GC and the feed line 606.
The cut information of all addresses stored in 6 and 3B
Setting information for each shot in the illustrated shot memory-MS is transferred and written to the magnetic card 602. On the other hand, when the read button 22 is pressed, the G
The reading circuit is activated by the CR4 and GCR5 signals, and the cut information and shot setting information stored in the card can be transferred to each memory again and stored again. Therefore, if you store the setting information in each memory and then store the same information on a magnetic card, you will not be able to reset the settings even if the power to the device is cut off and the contents of each memory volatize. This is not necessary, and each shot can be easily reproduced simply by transferring the information on the card and distributing it to each memory.

Furthermore, the gate 605 is connected to both circuits 603 and 604, and is used to light up an error lamp LH which indicates a parity check and a write failure. 609

Reference numeral 613 designates an output circuit that decodes and reads out the rest position of the counter, and outputs the signal to the gate 405 (FIG. 3C) via the gate 614 and line 615, which are opened by the PUC signal generated when the power switch is turned on as described later. Connected to gate input.

The magnetic counter 609 mechanically stores the contents of the address register 406 even in the event of a power cut or power outage, so when the device is restarted, the contents of the register 406 will be saved.
As described above, since the cut number is set to the previous history position, the interrupted cut number is immediately instructed to the cut memory 416. ■ Power supply circuit section configuration (see Figure 3E) The power supply circuit section consists of a power supply section 702 and a circuit 703 that turns on/off the power supply lines of the servo motors M1 to M4.The power supply section 702 stores all memories and registers when the power is turned on. It has a circuit section 702R that forms a reset signal PUC that clears the counter.

704 turns the motor circuit ON/OFF by the CPU circuit described later.
It is an FF for F.

■ Central electronic process circuit configuration (see Figure 4) As shown in Figure 4, the CPU circuit basically specifies the address of the built-in microprogram unit 802 using the button input unit 800 on the console 101. The designation circuit 801 is activated, selects a program corresponding to the operated button from the program section, causes the command register 803 to take it out, and outputs a series of command execution control signals GSM, .

As described above, in the present invention, information corresponding to the setting of a desired mode of a controlled device such as a television camera is sequentially pre-stored in a storage device, and at the time of reproduction, the designated address portion of the storage device is sequentially reproduced. The system is configured so that a series of desired settings can be automatically performed. At the same time, an electric/mechanical step switch such as a magnetic counter was installed to mechanically memorize the order of reproduction modes, so even if the device is turned off and stopped, the final order from the previous time will be memorized when the device is used again. Therefore, it is extremely effective for a remote control device equipped with a point storage device that enables reproduction from the same rank.
