Abstract

PROBLEM TO BE SOLVED: To prevent number of times of rewrites of a recording means from easily reaching number of limit times due to the service life or the like, even when the adjustment content is stored in a form of manipulated variable data obtained from an output of a variable resistor or the like by recording manipulated variable data to the recording means, when the operation of the operating knob is finished. SOLUTION: A control section 85 of a camera adaptor 8A discriminates whether or not any output from A/D converter circuits 87A-87D have changed. When the discrimination indicates an affirmative result, the control section 85 sets a value '10' to a count, having a function of a timer. In the case that any of operating knobs HP, HW, VP, VW is continuously operated for a continuous operating period, the control section 85 keeps the count of the counter to be the value 10. When the operation of the knobs is finished, the control section 85 gradually reduces the count and clears the count to be zero. Then coordinate data are updated, in response to the changed data, and a corresponding content of a memory 88 is rewritten by updated coordinate data.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation amount recording device and a camera device, and can be applied to, for example, a broadcast camera system. According to the present invention, when the operation of the operating element is completed based on the operation amount data obtained from the variable resistor output or the like, the operation amount data is recorded in the recording unit, so that the number of times of rewriting of the recording unit is limited by the life or the like The number of adjustments is not easily reached, so that adjustment contents and the like can be held.

[0002]

2. Description of the Related Art Conventionally, a broadcast camera system is configured so that various adjustment items such as black level and gamma adjustment can be finely adjusted, thereby providing a high quality image to a viewer. ing.

[0003] Such adjustment items are recorded in, for example, a battery backup memory, so that, for example, the adjustment contents set the day before can be reproduced, and continuous scenes can be imaged.

[0004]

However, when the adjustment contents are stored in such a memory for battery backup, attention must be paid to the consumption of the battery, and there is a drawback that the management becomes complicated accordingly.

As one method for solving this drawback, it is conceivable to use an electrically erasable read only memory (EEPROM) instead of a battery backup memory. In this case, when the power is turned off, the contents of adjustment of each circuit block and the like are recorded in this EEPROM, and then the power is cut off, so that this kind of adjustment can be held.

However, in this case, if the power supply is cut off due to running out of the driving battery, power outage, or the like, it becomes difficult to record the adjustment details in a record.

It is considered that such unpredictable shutoff of the power supply can be dealt with by updating the contents of the memory every time the adjustment contents are changed. However, if the contents of the memory are updated each time the contents of the adjustment are changed, the contents of the memory will be updated very frequently, for example, with respect to the contents of the adjustment by a variable resistor or the like. There is a problem that the service life is reached in a short time.

The present invention has been made in consideration of the above points, and even when the adjustment contents are held by the operation amount data obtained from the output of the variable resistor, the number of times of rewriting of the recording means is reduced to the number of times limited by the life or the like. It is an object of the present invention to propose an operation amount recording device and a camera device which can be prevented from being easily reached.

[0009]

According to the present invention, in order to solve the above-mentioned problems, the present invention is applied to an operation amount recording device and a camera device, and operates based on operation amount data that changes according to the operation amount of an operation element. When the operation of the child is completed, the operation of the recording means is controlled to record the operation amount data.

If the operation amount data is recorded in the recording means after the operation of the operation element is completed based on the operation amount data, the operation amount data can be recorded without frequently updating the contents of the recording means. Can be. Therefore, the present invention can be applied to recording of operation amount data by a variable resistor, a rotary encoder, or the like, and an adjustment amount or the like by these operations can be recorded.

FIG. 2 is a schematic diagram showing a camera operation system according to an embodiment of the present invention. The camera operation system 1 is configured so that a plurality of camera systems can be connected as needed. In this embodiment, three camera systems 2A, 2B, and 2C are connected. Here, since these three camera systems 2A, 2B, and 2C have the same configuration,
In the following description, the first camera system 2A will be mainly described, and other camera systems 2B and 2C will be denoted by the corresponding reference numerals, and redundant description will be omitted.

The camera system 2A is configured by connecting a camera body 5A and a remote control panel 4A via a camera control unit (CCU) 3A. Other camera systems are connected via the camera control unit (CCU) 3A. 2B and 2C, and further to an external device such as a switcher.

Here, the remote control panel 4A
Is arranged on the coordinating desk together with the remote control panels 4B and 4C of the other camera systems 2B and 2C, for example.
In response to an operation of an operator or the like arranged on the operation panel of the remote control panel 4A, data communication is performed with the camera control unit 3A to control the operation of the camera body 5A, and to control other camera systems. The operation of the camera bodies 5B and 5C of 2B and 2C is controlled.
This allows the camera operation system 1 to operate the remote control panel 4A to variously adjust the imaging conditions and the like.

The camera control unit 3A performs data communication with the camera body 5A in response to the operation of an operator or the like disposed on the operation panel of the camera control unit 3A, thereby controlling the operation of the camera body 5A. Control. This allows the camera operation system 1
Thus, even if the camera control unit 3A is operated, various conditions such as imaging conditions can be adjusted.

Further, the camera control unit 3A comprises:
Data communication between the remote control panel 4A and the camera body 5A is relayed, and data communication is performed with the other camera systems 2B and 2C according to the settings of the operator. Thereby, in the camera operation system 1, one remote control panel 4A, 4B,
By operating the camera 4C, the imaging conditions in the camera bodies 5A, 5B, and 5C can be adjusted in conjunction with each other.

Further, the camera control unit 3A includes:
The video signal transmitted from the camera body 5A is output to a predetermined external device, and the video signal of the return image and the video signal for the prompter input from the external device and the like are sent to the camera body 5A.

The camera body 5A is a television camera 6
A, a viewfinder 7A attached to the television camera 6A, and a camera adapter 8A.

The camera adapter 8A has a plurality of controls on the back, and communicates with the television camera 6A in response to the operation of the controls.
The operation of A is switched. Thus, in the camera operation system 1, a predetermined adjustment item can be independently adjusted by the cameraman.

Further, the camera adapter 8A relays data communication between the camera control unit 3A and the television camera 6A,
A sends a video signal output from the camera control unit 3A to the camera control unit 3A.
Then, the return image and the video signal for the prompter transmitted to the television camera 6A are output.

The television camera 6A is controlled by the camera adapter 8A to control the camera adapter 8A.
Under the control of the camera control unit 3A, the remote control panel 4A, and the like via the CPU, imaging conditions are set, a desired subject is imaged according to the set conditions, and a video signal resulting from the imaging result is processed and output. .
At this time, the television camera 6A outputs a video signal for monitoring to the viewfinder 7A.

FIGS. 3 and 4 are block diagrams showing a signal processing system of the television camera 6A. The television camera 6A receives a light beam from a subject by a lens 12 having a built-in aperture 11, and separates the light beam into red, green, and blue light beams by a color separation prism 14. The CCD solid-state imaging devices 13R, 13G, and 13B for red, green, and blue are:
Red, green, and blue light rays are received, and red, green, and blue color signals R, G, and B, which are the light reception results, are output.

At this time, the diaphragm 11 is
The driving conditions of the iris driving unit 16 are controlled by the control unit 15 so that, for example, the amount of light incident on the CCD solid-state imaging devices 13R, 13G, and 13B is controlled to a predetermined value. The CCD solid-state imaging devices 13R, 13G, and 13B are driven by a driving signal generated by the sensor driving unit 17, and the timing of the driving signal is set to change continuously under the control of the control unit 15, Thus, the charge storage time can be continuously varied. Thereby, in the television camera 6A, the so-called electronic shutter speed is continuously variably adjusted so that flicker does not occur in the imaged result even when, for example, a computer display is imaged.

Analog process (AP) 18R, 18
G and 18B switch the operation under the control of the control unit 15, and the CCD solid-state imaging devices 13R, 13G and 13B respectively.
Red, green, and blue color signals R, G, and B output from B
Is corrected and output. At this time, the analog processes 18R, 18G, and 18B switch the gain of the amplifier circuit, and thereby switch the gain of the video signal output from the television camera 6A.

The analog processes 18R, 18G, 1
8B sets the black level and the white level of the color signals R, G, and B to predetermined signal levels, respectively, and outputs them. In setting the signal level, when the black level is set by operating the master black, the analog processes 18R, 18R
G and 18B correct the black level in conjunction with the red, green and blue color signals R, G and B. On the other hand, when setting the black level by operating the black balance,
Under the control of the control unit 15, the black level of the red and blue color signals R and B is corrected. When the white level is set by the white balance, the control unit 1
Under the control of 5, the white level is corrected for the red and blue color signals R and B.

Thus, in the television camera 6A,
By controlling the operations of the analog processes 18R, 18G, and 18B, the adjustment items of gain, master black, black balance, and white balance can be adjusted.

Further, a signal level similar to the color difference signal is divided by a signal similar to the luminance signal, whereby the digital color signal D
Two sets of color area detection signals whose signal levels change only according to the hues of R, DG, and DB are generated. Further, the color area extraction unit 24 compares the color area determination reference value set by the control unit 15 with each color area detection signal, and thereby detects a predetermined color area in the digital color signals DR, DG, and DB.

The coefficient supply unit 25 includes a color area extraction unit 24

The digital color signals DR and DG output from R, 21R, 20G and 21G are received, and contour emphasis signals DA and DB are generated by arithmetic processing of these digital color signals. At this time, the image enhancer 27 switches its operation under the control of the control unit 15 and varies the signal levels of the contour emphasis signals DA and DB, thereby varying the degree of contour emphasis. Further, based on the detection result of the color region extraction unit 24, the signal levels of the outline emphasis signals DA and DB are varied so as to reduce the degree of outline emphasis for the skin color portion. Thus, in the television camera 6A, for example, the contour of a person's face or the like is not unnaturally emphasized.

That is, the remote control panel 4A
Are variable resistors 59B1 to 59B1 assigned to various operators (indicated by reference numerals of the corresponding operators in FIG. 7).
The power supply voltage VC is determined by 67B1, 68B, and 69B, respectively.
C is divided, and the divided voltage VD is subjected to analog-to-digital conversion processing by the corresponding analog-to-digital conversion circuits 76A to 76M. As a result, the remote control panel 4A connects the variable resistors 59B1 to 67B1, 68B,
The power supply voltage VC which is the reference voltage according to the manipulated variable of 69B
A divided voltage VD obtained by dividing C is generated, and divided data DV corresponding to the voltage value of the divided voltage VD is generated.

The control unit 75 is constituted by a microcomputer, and each of the analog / digital conversion circuits 76A to 76A
The divided voltage data DV output by the 6M
Monitor with 3A etc.

Here, when the operation mode of the remote control panel 4A is set to a partially locked state or a normal operation state by the operation rotary switch 56A, the control unit 75 accepts the operation of various operators.

As described above, in the partially locked state or the normal operation state and the state in which the slave mode is not set, the manual adjustment of the aperture is selected by operating the switch arranged on the aperture adjustment operation unit 68. Then, the control unit 75 takes in the partial pressure data DV corresponding to the aperture adjustment operation element 68B at a predetermined cycle. Further control unit 7
5 accesses the first conversion table set in the correction table 78 using the data value of the fetched partial pressure data DV as an address, and detects the corresponding operation amount data.

Here, in the correction table 78, the first
To the third conversion table. In the first conversion table, a conversion table of input / output characteristics as shown in FIG. 8 is formed. In other words, the conversion table outputs the data value of the value 00h even if the divided voltage data DV formed of the analog-to-digital conversion value does not completely fall to the value 00h.
Even if V does not completely rise to the value FFh, the input / output characteristic shows a saturation characteristic in the vicinity of the values 00h and FFh so that the data value of the value FFh is output, and the other part AR1 is proportional to the input data value. The characteristic is set so as to output the changed data value.

Thus, the control unit 75 operates the diaphragm operation element 68B due to the impedance of the power supply line, etc., so that even if the divided voltage VD does not change with a sufficient dynamic range in a predetermined range, the data of the divided voltage data DV can be obtained. By correcting the value, the aperture can be opened and closed sufficiently.

Further, before and after the middle point click position of the variable resistor, the input / output characteristics are set so that the output data is maintained at a constant value even if the input data value changes.

As a result, the control section 75 also ensures a sufficient dynamic range for the master black operator 69B, and can sufficiently adjust the master black. Also, at this time, even when the operation element 69 is displaced so as to be drawn to the position of the middle point click near the center click of the operation element 69B requiring high-precision adjustment, it is possible to output the data value in the vicinity of the middle point click.

On the other hand, in the state where the normal operation state is set and the slave mode is not set, the manual adjustment of the white balance is selected by operating the switch arranged on the operation unit 66. In this case, the control unit 75 controls the operating elements 66B1, 66B2.
Is acquired in a predetermined cycle, the third conversion table set in the correction table 78 is accessed based on the acquired partial pressure data DV, and the corresponding operation amount data is detected. Further, the detected operation amount data is output to the camera control unit 3A.

Here, the third conversion table is shown in FIG.
, As in the first and second conversion tables,
Even if the divided voltage data DV does not completely change to the value 00h or the value FFh, the input / output characteristics may be saturated near the values 00h and FFh so that the data of the value 00h or the value FFh is output. The input / output characteristics are set, and in the remaining area, the input / output characteristics are set so that the output data value changes in proportion to the input data value. Further, in the remaining area, in a predetermined area inside the saturation area, the input / output characteristics are set so that the output data value greatly changes in proportion to the input data value. The input / output characteristics are set so that the change in the data value is small.

As a result, the control unit 75 ensures a sufficient dynamic range even in white level adjustment, and provides a sufficient resolution for the rotational operation amount in the vicinity of the center of the operators 66B1 and 66B2 for which high-precision adjustment is required. Thus, the operation amount data can be output, whereby the adjustment accuracy can be improved.

As a result, the control unit 80 operates the iris operation element 48B to ensure a sufficient dynamic range, thereby enabling the iris to be sufficiently adjusted. Thus, the control unit 80 outputs the detected operation amount data to the camera adapter 8A.

Further, in a partially locked state or a normal operation state, and in a state where the slave mode is not set, the control unit 80 operates the master black operator 4
The divided voltage data DV corresponding to 9B is taken in a predetermined cycle.

Further, the control unit 80 outputs the detected operation amount data to the camera adapter 8A. Thereby, the control unit 80 sets the camera control unit 3A
Also, in the adjustment of the master black, a sufficient dynamic range and adjustment accuracy can be ensured.

When manual adjustment of white balance or black balance is selected by operating the switches 47A1 to 47A3 in a partially locked state or a normal operation state and the slave mode is not set, the control unit is controlled. Reference numeral 80 similarly inputs the divided voltage data DV from the corresponding analog-to-digital conversion circuit at a predetermined cycle, detects operation amount data from the third conversion table set in the correction table 82, and detects the detected operation amount data. Is output to the camera adapter 8A. Thus, the control unit 80 can ensure a sufficient dynamic range and adjustment accuracy in white balance adjustment and black balance adjustment also in the camera control unit 3A.

In the same state, the control unit 80 fetches the divided voltage data DV corresponding to the gamma adjustment operation element 46B at a predetermined cycle, and uses the fetched divided voltage data DV to generate the second divided data.
And outputs the corresponding operation amount data to the camera adapter 8A. Thereby, the control unit 8

When 1 to 43C2 is pressed, the information is notified to the camera adapter 8A.

When notifying the camera adapter 8A of the operation data in this way, the control unit 85 determines whether or not each variable resistor is continuously operated, and when the operation is completed, the setting is performed by the continuous operation. The contents of the adjustment made are recorded in the memory 83. Thereby, in the camera operation system 1, even after the power is once turned off,
It is designed to be able to reproduce the state immediately before the interruption. Here, the memory 83 is constituted by an electrically erasable read only memory (EEPROM).

As shown in FIG. 11, the camera adapter 8
A notifies the television camera 6A of such a notification from the camera control unit 3A via the control unit 85 having a microcomputer configuration. Further, the camera adapter 8A controls the display of a box cursor on the viewfinder 7A in response to the operation of an operation element arranged on the back.

As shown in FIG. 12, in this embodiment, the television camera 6A displays the first and second box cursors W1 and W2 on the display screen of the viewfinder 7A by the selection of the cameraman. These box cursors W1 and W2 are used to confirm the display position of the telop and the like, and to confirm the position of the target subject.

The camera adapter 8A has a switch 86 for switching a box cursor on the rear side and operators HP, HW, VP, and VW using variable resistors. Of these operators, the horizontal operators HP and HW are used to set the horizontal center position and width of the box cursors W1 and W2, respectively. In addition, a vertical control V
P and VW are used to set the vertical center position and width of the box cursors W1 and W2, respectively.
These variable resistors respectively divide the power supply voltage VCC,
The divided voltage VD is subjected to analog-to-digital conversion processing by the corresponding analog-to-digital conversion circuits 87A to 87D, and the resulting divided data DV is output to the control unit 85.

When the mode for displaying the first box cursor is selected by operating the switch 86, the control unit 85 notifies the television camera 6A of this operation, and the first coordinate value stored in the memory 88 The data is loaded and transmitted to the television camera 6A. Here, the memory 83 is a read-only memory (E
EPROM). In this state, the correction table 89 is accessed by each partial pressure data DV, and the operation amount data stored in the correction table 89 is detected. Here, the correction table 89 stores a first conversion table among the correction tables arranged in the camera control unit 3A.

The controller 85 monitors the operation amount data obtained from the conversion table, and when the operation amount data changes, sequentially corrects and outputs the coordinate value data according to the change amount. As a result, the control unit 85 controls the operating elements HP, HW, and V while displaying the first box cursor W1.
The display position and width are changed in response to the operations of P and VW.

When the mode for displaying the second box cursor in place of the first box cursor is selected by operating the switch 86, the control unit 85 operates the memory 88.
Is loaded and transmitted to the television camera 6A. In this state, each partial pressure data DV
To access the correction table 89, and the operation amount data stored in the correction table 89 is detected. Further, when the operation amount data changes, the coordinate value data is sequentially corrected and output according to the change amount. Thereby, the control unit 8
Reference numeral 5 switches the display of the box cursor to the second box cursor W2, and changes the display position and width of the second box cursor W2 in response to the operation of the controls HP, HW, VP, and VW.

When the display position and width of the box cursor are changed in this manner, the control unit 85 changes the coordinate value based on the manipulated variable data whose data value has been corrected by the first conversion table of the correction table 89. As a result, a sufficient dynamic range can be ensured for the operation of the operators HP, HW, VP, and VW, and the position of the box cursor and the like can be sufficiently varied on the display screen of the viewfinder 7A.

When notifying the television camera 6A of the coordinate data of the first or second box cursor in this way, the control unit 85 sets the variable resistors HP and H
It is determined whether or not W, VP, and VW are continuously operated, and when the continuous operations are completed, the coordinate values set by the continuous operations are recorded in the memory 88. This allows the camera operation system 1 to reproduce the state immediately before the power is turned off even after the power is once turned off. Further, even if the display is switched by the first and second box cursors, the immediately preceding display can be reproduced, so that the first and second box cursors can also be used as adjustment operators. .

The television camera 6A inputs the notification from the camera control unit 3A and the notification from the remote control panel 4A input to the control unit 15 through the camera adapter 8A. Further, the control unit 15 outputs control data to each processing circuit,
Thereby, the imaging conditions are switched in response to the operations of the camera control unit 3A and the remote control panel 4A.

That is, when the operation amount data corresponding to the aperture adjustment is input, the control unit 15 outputs control data to the iris driving unit 16 in response to the operation amount data.
The aperture 13 is controlled. When operation amount data corresponding to shutter speed adjustment is input, control data is output to the sensor driver 17 in response to the operation amount data, and C
The charge accumulation time of the CD solid-state imaging devices 13R, 13G, and 13B is controlled.

When operation amount data corresponding to the master black adjustment is input, the corresponding control data is output to the analog processes 18R, 18G, and 18B to correct the black levels of the color signals R, G, and B. When the operation amount data corresponding to the white balance adjustment and the black balance adjustment is input, the analog processes 18R and 18B similarly perform the white level adjustment of the color signals R and B,
Correct the black level.

Further, when the operation amount data corresponding to the contour adjustment is input, the operation of the image enhancer 27 is controlled to correct the signal levels of the outline emphasis signals DA and DB, and the operation amount data corresponding to the gamma adjustment is input. In this case, the operation of the gamma circuits 30R, 30G, and 30B is switched.

On the other hand, when the control unit 15 is notified of the operation of the operating element 52A such as the standard setting, the standard memory 90
The control command is issued to each circuit block according to the setting of the standard value held in the TV camera 6A, thereby setting the television camera 6A to the standard imaging condition. In addition, when the operation of the operation element is notified of automatic aperture adjustment, automatic white balance adjustment, and the like, the aperture and the like are controlled by executing a corresponding processing procedure.

On the other hand, when the selection display of the box cursor is notified, the control unit 15 drives the marker generator 91 based on the subsequently input coordinate value data, whereby the signal level at the box cursor part is obtained. Is generated, and the addition circuit 92 adds the video signal and the video signal YVF for the viewfinder and outputs the result to the viewfinder 7A. Thereby, the television camera 6A displays the box cursor in the display mode specified by the camera adapter 8A.

FIG. 1 and FIG. 13 are flowcharts showing the writing process to the memories 83 and 88 executed in the control units 85 and 80 in this manner. In addition, since this processing procedure is common to the control units 85 and 80, here, the processing procedure will be described focusing on the control unit 85, and redundant description will be omitted.

That is, the control unit 85 executes the processing procedure of FIG. 13 in parallel with other processing procedures, and proceeds from step SP1 to step SP2. Here, the control unit 85 monitors the outputs of the analog-to-digital conversion circuits 87A to 87D and determines whether or not the output value of any of the analog-to-digital conversion processes has changed. If a negative result is obtained here, the control unit 85 returns to step SP2.

On the other hand, if a positive result is obtained, the control section 85 proceeds to step SP3, sets a value 10 to a counter having a timer function, and returns to step SP2. As a result, the control unit 85 controls the operating elements HP, HW, V
When either P or VW is operated continuously, this processing procedure is repeated to always set the value of the counter to the value 10.

Apart from this processing procedure, the control unit 85 executes the interrupt processing procedure shown in FIG. 13 at a constant cycle.
That is, the control unit 85 determines from step SP4 to step S
The process proceeds to P5, where it is determined whether the value of the counter is 0 or not. Here, if a positive result is obtained, the control unit 85 proceeds to step SP6 and ends the processing of this interrupt.

On the other hand, if a negative result is obtained in step SP5, the control unit 85 proceeds to step SP7, decrements the counter by 1, and then proceeds to step SP8. Here, the control unit 85 determines whether or not the value of the counter is 1, and if a negative result is obtained, the control proceeds to step SP6.
Move on to Accordingly, the control unit 85 executes the processing procedure of FIG. 13 to hold the counter at the value 10 during the period in which the operation of the operation element is continued, and performs the processing in steps SP4 to SP4.
The processing procedure of 5-SP7-SP8-SP6 is repeated at an interrupt cycle, and when the operation of the operator is completed, the value of the counter is sequentially reduced. When the count value reaches the value 1,
The process moves from step SP8 to step SP9.

At step SP9, the control unit 85
Resets the counter to a value of zero. In the following step SP10, the coordinate value data is updated according to the changed data value, and the contents of the corresponding area of the memory 88 are rewritten with the updated coordinate value data. Thus, the control unit 85 records the adjusted contents in the memory 88 when a predetermined time elapses after the continuous operation is completed.

On the other hand, in the control unit 80, similarly, the data of the adjustment value by the various variable resistors
1 and 13 are executed on the operation amount data output from the remote control panel 4A, and when a predetermined time has passed after the continuous operation is completed, the adjusted contents are recorded in the memory 83. It has been made like that.

In addition, the control unit 80 records the setting contents in the memory 83 each time each switch is operated. Also, the up / down controls 43C1, 43
Regarding C2 and 61C1 to 62C2, the contents adjusted at the timing when these operators are turned off are stored in the memory 8.
Record in 3. By these processes, the control units 85 and 88
In, the contents of the memory 83 are rewritten at a frequency sufficient for practical use so that the number of times of rewriting of the memory 83 does not easily reach the limit number due to the life.

In the above configuration, in the camera operation system 1 (FIG. 2), the operations of the various controls arranged on the remote control panels 4A, 4B, 4C are performed by the camera control units 3A, 3B, 3C, respectively.
C is notified, and the operation mode of each camera system 2A, 2B, 2C is set. Similarly, the operation mode is set by the direct operation of the operators of the camera control units 3A, 3B and 3C.

That is, the operation switch 40
By operating the buttons A and 56A (FIGS. 5 and 6), a locked state in which the operation of the operation element is not accepted is formed in the camera control units 3A, 3B and 3C and the remote control panels 4A, 4B and 4C, respectively. In addition, a partially locked state is formed in which only the controls 48B and 68B of the aperture adjustment and the controls 49B and 69B of the master black adjustment are received, and a normal operation state in which the operations of all the controls are received is formed. You.

The remote control panels 4A, 4A
By operating the master / slave switches 53A and 54A of B and 4C, the television camera set to the master mode and the slave mode, and the imaging conditions are set in conjunction with the camera system set to the master mode. A switching state is formed.

Furthermore, the remote control panel 4A,
The link mode is set by operating the link switch 71A of the link 4B, 4C, and a state is established in which the adjustment of the aperture and the master black are interlocked between the camera systems set to the link mode.

The setting for such mode switching is as shown in FIG.
11), a remote control panel, a camera control unit, a camera adapter, and data communication between the control units 75, 80, 85, and 15 arranged in the television camera, and the camera systems 2A, 2B, and 2
This is executed by data communication between the camera control units in C.

After the operation mode is set as described above, when the operator selects manual adjustment of the aperture, the divided voltage VD of the variable resistor corresponding to the aperture adjustment operators 48B and 68B is changed to analog-digital. The conversion circuit 81A converts the voltage data into the divided voltage data DV, and the data value of the divided voltage data DV is corrected by the first conversion table of the correction table 82 to generate operation amount data. At this time, the partial pressure data DV is displayed on the aperture adjustment operator 48B,
At both ends of the 68B operation range, the saturation region is set so that the minimum and maximum data values 00h and FFh are obtained (FIG. 9), and the data of the operation amount data is proportional to the data value of the partial pressure data DV. The data value is corrected so that the value changes, and is converted into operation amount data.

Further, the correction value data is notified to the television camera 6A, and the aperture 13 (FIG. 2) is controlled so as to correspond to the correction value data. Thus, even when the power supply voltage and the ground potential are different between the analog-to-digital conversion circuit and the variable resistor, a sufficient dynamic range can be secured and the operation amounts of the operators 48B and 68B can be detected, and the aperture can be sufficiently opened and closed. be able to.

On the other hand, when the manual adjustment of the master black is selected by the operator, similarly, the divided data DV is generated from the divided voltage VD of the variable resistor corresponding to the master black adjustment operators 49B and 69B. The data value of the divided voltage data DV is
The operation amount data is generated by correction using the second conversion table. At this time, a saturation region is set in the partial pressure data DV so that the minimum and maximum data values 00h and FFh are obtained at both ends of the operation range of the master black adjustment operators 49B and 69B (FIG. 10). The data value is corrected so that the data value of the manipulated variable data changes in proportion to the data value of the partial pressure data DV, and is maintained at a constant value before and after the middle point click position. Is converted to

Further, the correction value data is notified to the television camera 6A, and the analog processes 18R, 18G, and 18B correspond to the correction value data.
The black level of each color signal R, G, B is corrected. Thus, even when the power supply voltage and the ground potential are different between the analog-to-digital conversion circuit and the variable resistor, a sufficient dynamic range is secured and the operation amounts of the operators 49B and 69B are detected, and the white balance and the black The balance can be adjusted. In addition, the adjustment accuracy can be improved near the standard level corresponding to the position of the midpoint click.

When manual adjustment of white balance or black balance is selected by the operator,
Similarly, the operators 47B1 to 47B4, 66B1, 6
6B2, 67B1 to 67B3, the divided voltage DV is generated from the divided voltage VD of each variable resistor, and the data value of the divided data DV is corrected by the third conversion table of the correction table 82, and the operation amount is adjusted. Data is generated.
At this time, the partial pressure data DV is the operation elements 47B1 to 47B.
4, 66B1, 66B2, 67B1 to 67B3 at both ends of the operation range, the minimum and maximum data values 00h
And FFh are obtained (FIG. 1)
1) The data value is corrected so that the data value of the manipulated variable data changes in proportion to the data value of the partial pressure data DV, and further, the resolution is improved in the center portion of the operation range, and the data is corrected into the manipulated variable data. Is converted.

Further, the correction value data is notified to the television camera 6A, and in the analog processes 18R, 18G, 18B, corresponding to the correction value data.
The black and white levels of the red and blue color signals R and B are corrected. Thereby, even when the power supply voltage and the ground potential are different between the analog-to-digital conversion circuit and the variable resistor, a sufficient dynamic range is secured and the operators 47B1 to 47B
By detecting the operation amounts of B4, 66B1, 66B2, 67B1 to 67B3, white balance and black balance can be adjusted within a sufficient range. Further, the adjustment accuracy can be improved in an area near the center where the setting frequency is high.

When the operator selects manual adjustment of contour emphasis or gamma, similarly, the divided voltage data DV of each variable resistor corresponding to the operator 45B, 61B or 46B, 64B is stored in the correction table 82 in the same manner. The operation amount data is generated after being corrected by the conversion table of FIG.
Further, the correction value data is notified to the television camera 6A, the signal levels of the edge enhancement signals DA and DB generated by the image enhancer 27 are variably controlled to correspond to the correction value data, and the gamma circuits 30R and 30R are controlled.
The input and output characteristics of G and 30B are switched. As a result, a sufficient dynamic range can be ensured to adjust the outline emphasis or the gamma, and the adjustment accuracy can be improved near the standard level corresponding to the position of the middle point click.

On the other hand, when the operator selects manual adjustment of the knee on the remote control panel 4A, similarly, the divided voltage data DV of each variable resistor corresponding to the operation element 65B is stored in the correction table 82 in the correction table 82. The operation amount data is generated after being corrected by the conversion table of No. 3. Further, the correction value data is notified to the television camera 6A, and the input / output characteristics of the knee correction circuits 28R, 28G, 28B are switched so as to correspond to the correction value data. As a result, the knee adjustment can be performed while securing a sufficient dynamic range, and the adjustment accuracy can be improved in a frequently set region near the center.

As described above, the operation of each variable resistor in the remote control panel and the camera control unit is monitored by the control unit 80 of the camera control unit at a constant cycle when the operation of each variable resistor is accepted. 12) When any of the operable variable resistors is operated, the operation is detected by a change in the divided voltage data and the operation amount data, and a value 10 is set to a counter that functions as a timer in each cycle. As a result, the counter is kept set to the value 10 during the period when these operators are continuously operated.

[0125] In addition, by the interruption of a fixed period (Fig. 1),
The control unit 80 decrements the count value of the counter, and when the count value becomes 1, resets the count value and records the adjusted content in the memory 83.

When a predetermined time elapses after the continuous operation is completed, the adjusted contents are recorded in the memory 83, and the contents of the memory 83 are rewritten with sufficient frequency for practical use. The limit is not easily reached.

In the setting operation of the switches, the operation contents are recorded in the memory 83 with the pressing operation of each switch as a trigger, and in the shutter speed and the gamma adjustment on the remote control panel side, the up / down operator is operated. The adjustment contents are stored in the memory 8 at the timing of turning off.
