Description

  The present invention relates to an imaging system, and more particularly to an imaging system in which an imaging device and a demand for controlling the imaging device are connected by wireless communication.

  Conventional television lens devices (hereinafter referred to as lens devices) have movable optical parts such as a zoom lens, a focus lens, and an iris. The lens device is connected to a zoom demand, which is a zoom driving command device, or a focus demand, which is a focus driving command device, and drives the movable optical unit. Normally, the lens device and the demand are connected via a cable connection using a multi-pin connector, but a technique for connecting the lens device and the demand by wireless communication has been proposed (Patent Document 1). . In recent years, local wireless communication systems such as Bluetooth (registered trademark) and wireless LAN using 2.4 GHz band wireless radio waves that can be used without a wireless license have been widely used. In order to make devices compatible with these wireless communication systems communicable with each other by wireless communication, communication information can be communicated by manually inputting and registering each other's device identification information into each device. Has realized a state. This registration process is called pairing. When pairing is completed, a connection between desired devices is established by calling a connection destination using the registered recognition information. Furthermore, for devices that do not have a key input unit or a display unit, a technology has been proposed in which peripheral wirelessly connectable devices are searched, a desired connection destination is selected from the search result, and recognition information is registered ( Patent Document 2).

  For example, in Patent Document 1, a signal conversion unit is connected to a lens device and a demand, and wireless communication is performed between the signal conversion units, so that the connection between the devices can be easily performed even when the lens device and the command device are separated. A lens system is disclosed. Patent Document 2 discloses a wireless connection device that executes a registration process for wireless connection and establishes wireless communication with a simple operation even in a device that does not have a key input unit or a display unit.

JP 2007-293070 A Japanese Unexamined Patent Publication No. 7-46671

  In the prior art disclosed in Patent Document 1, a pair of wireless devices connected to a lens device and a demand are used. However, in photographing such as television broadcasting, a plurality of photographing devices are used. There may be multiple sets. A device such as Bluetooth (registered trademark) or a wireless LAN is assigned a unique address represented by a 48-bit length for wireless communication, and it is necessary to register a connection destination address. Since communication connection between wireless devices is performed by designating a registered connection destination address, the connection destination is inevitably fixed. When there are multiple sets of wireless devices, it is more convenient for the user to specify a desired connection destination than to fix the connection destination. Therefore, it is possible to switch by registering a plurality of addresses, assigning the address of the connection destination to be called to a switch, etc., and selecting a desired connection destination from a plurality of connection destinations at one connection source and performing wireless connection Conceivable. However, since wireless devices that connect these lens devices and demands do not have a user interface such as a key input unit or a display unit, it is extremely difficult for a user to register a plurality of connection destination addresses. is there. Furthermore, since the wireless device can be easily detached from the lens device, the combination of the wireless devices connected to the lens device may change or the number of wireless devices used may change depending on the shooting situation. Imagine. For example, as one of the uses of the wireless device, it may be used for a lens device installed in a crane. However, a crane is often used for shooting a music program, and is rarely used for shooting a news program. . Therefore, if the program to be photographed changes, the number of wireless devices also changes. Therefore, the user may not be able to recognize the connection destination assigned to the switch.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an imaging system that facilitates registration of a plurality of connection destinations by a user and allows the user to easily know a plurality of selectable connection destinations.

The photographing system includes a photographing device 1, a slave unit 2 that is a wireless device connected to the photographing device 1, a demand 3, and a master unit 4 that is a wireless device connected to the demand 3.

  The photographing apparatus 1 includes a lens unit that includes an optical system including a movable optical member such as a focus lens, a zoom lens, and an iris (not shown), and a camera unit that includes an image sensor including a CCD sensor, a CMOS sensor, or the like. In this embodiment, an imaging device in which a lens unit and a camera unit are integrated will be described. However, the lens unit and the camera unit are separate bodies, and the lens unit can be attached to and detached from the camera unit. It may be. The photographing apparatus 1 includes a serial communication unit 11 that receives a command signal for instructing driving of the movable optical member, and drives the movable optical member.

  In the slave unit 2, the serial communication unit 21 is connected to the serial communication unit 11 of the photographing apparatus 1 and transmits / receives digital data. The camera number setting SW 22 serving as an identification number acquisition unit is a selection switch for setting the camera number (identification number) of the photographing apparatus 1 to which the slave unit 2 is connected, and is set by the user. In television broadcasting, shooting is performed using a plurality of shooting devices. Therefore, in order to identify the photographing apparatus, each photographing apparatus is numbered and operated. The camera number setting SW 22 is for setting the number of the numbered photographing device (camera number). The camera number setting SW 22 is, for example, a rotary switch having a sufficient number of contacts for setting the number (number) of imaging devices that can exist. In the present embodiment, the identification number is exemplified and described as information for identifying a plurality of photographing apparatuses. However, the present invention is not limited to this, and is not limited to the number, and various characters and the like can be used. The identification information can be used in place of the identification number.

  The wireless communication unit 23 has an antenna and transmits / receives data by wireless communication. The CPU 24 controls the serial communication unit 21 and the wireless communication unit 23 to perform data transmission / reception.

  The demand 3 includes an operation unit that is operated by a user (not shown), and generates a command signal that instructs driving of the movable optical member included in the photographing apparatus 1 according to the operation direction and the operation amount of the operation unit. The demand 3 includes a serial communication unit 31, and the serial communication unit 31 transmits a command signal for the movable optical member to the master unit 4.

  In the master unit 4, the serial communication unit 41 is connected to the serial communication unit 31 of the demand 3 and transmits / receives digital data. The connection destination selection SW 42 (connection destination selection means) is a switch that alternatively selects the slave unit 2 that performs wireless connection. For example, a rotary switch having a sufficient number of contacts (the same number of contacts as the camera number setting SW 22) to select the number (number) of imaging devices that may exist. The wireless communication unit 43 includes an antenna and transmits / receives data by wireless communication.

  The CPU 44 controls the serial communication unit 41 and the wireless communication unit 43 to transmit / receive data. Further, the CPU 44 performs processing (pairing) for registering an address unique to the slave unit 2 for wireless communication. The pairing instruction SW 45 (pairing instruction means) is a switch for instructing execution of pairing. When instructed by the user, pairing processing is executed. Details of the pairing process will be described later.

  In this embodiment, a pairing mode, which is a processing mode for registering the address of a slave unit in the master unit, and a processing mode for establishing a wireless connection between the master unit and the slave unit and transmitting / receiving command signals of the movable optical member. Has normal connection mode.

  The flowchart in FIG. 2 shows the flow of wireless communication processing in the normal connection mode. The CPU 24 and the CPU 44 control these processes according to a computer program stored in a memory (not shown).

The processing of the CPU 44 of the master unit 4 is shown in FIG. 2A, and the processing of the CPU 24 of the slave unit 2 is shown in FIG. 2B. Dotted arrows indicate the flow of wireless communication. The CPU 44 performs wireless communication via the wireless communication unit 43 and the CPU 24 performs wireless communication via the wireless communication unit 23.
When the slave unit 2 enters the normal connection mode, the processing of the CPU 24 proceeds to step S21 and waits for reception of a connect command from the master unit 4.

  When the master unit 4 enters the normal connection mode, the processing of the CPU 44 proceeds to step S11, reads the switch number that is the selected position selected by the connection destination selection SW 42, and registers (stores) it corresponding to the switch number. Reads the address of the slave unit 2 being The pairing process for registering addresses and associating them with switch numbers will be described later. When the address reading is completed, the process proceeds to step S12, and a connect command is transmitted to the slave unit. The connect command is transmitted with the address read and specified in step S11 and an authentication code set in advance. In the wireless device, an authentication code is used to ensure security, and a wireless connection is established when the authentication code preset in each wireless device matches. When the transmission of the connect command is completed, the process proceeds to step S13 to wait for reception of the connect OK command from the slave unit 2.

  Next, when the CPU 24 of the slave unit 2 receives the connect command in step S21, the process proceeds to step S22, in which it is determined whether the address and the authentication code accompanying the connect command are correct. In the address, it is determined whether or not the received address matches its own address, and if it matches, it is recognized that the command is for itself. In the authentication code, it is determined whether or not it matches the preset authentication code. If they match, it is recognized that the connection is normal. If both the address and the authentication code match, the process proceeds to step S23, and if either one is different, the process returns to step S21 and waits for the reception of the connect command again. In step S23, a connect OK command is transmitted to the master unit 4 that has transmitted the connect command. When the connect OK command is transmitted, the process proceeds to step S24 to wait for reception of a command signal.

  Next, the processing of the CPU 44 of the master unit 4 proceeds to step S14 when the connect OK command is received in step S13. Thus, wireless communication between the master unit 4 and the slave unit 2 is established. In step S14, a command signal for the movable optical member is received via serial communication with the demand 3. When the reception is completed, the process proceeds to step S15. In step S15, the command signal received in step S14 is transmitted to the slave unit 2 that has established communication. When the transmission is completed, the process proceeds to step S16 and waits for reception of an answer command from the slave unit 2.

  Next, when the CPU 24 of the slave unit 2 receives the command signal in step S24, the process proceeds to step S25. In step S25, the command signal received in step S24 is photographed via serial communication with the photographing apparatus 1. Transmit to device 1. The imaging device 1 drives the movable optical member by receiving the command signal. When the transmission of the command signal is completed, the process proceeds to step S26, and the answer signal from the photographing apparatus 1 is received. The answer signal is, for example, a position signal indicating the position of the movable optical member. When reception of the answer signal is completed, the process proceeds to step S27, and the answer signal received in step S26 is transmitted to the master unit 4. When the transmission of the answer signal is completed, the process returns to step S24, and the processes from step S24 to step S27 are repeated again.

Next, when the answer signal is received in step S16, the process of the CPU 44 of the master unit 4 proceeds to step S17. In step S17, the answer signal received in step S16 is transmitted to the demand 1. When the transmission is completed, the process returns to step S14, the processes from step S14 to step S17 are repeated, and transmission / reception of the command signal and the answer signal is repeated.
As described above, the wireless connection between the master unit 4 and the slave unit 2 is established, and the command signal of the demand 3 is transmitted to the photographing apparatus 1 by wireless communication, thereby realizing the driving of the movable optical member.

  The flowchart of FIG. 3 shows the flow of pairing processing for registering the address of the slave unit 2 in the master unit 4. The CPU 24 and the CPU 44 control these processes according to a computer program stored in a memory (not shown).

  Similar to FIG. 2, the processing of the CPU 44 of the master unit 4 is shown in FIG. 3A, and the processing of the CPU 24 of the slave unit 2 is shown in FIG. 3B. Dotted arrows indicate the flow of wireless communication. The CPU 44 performs wireless communication via the wireless communication unit 43 and the CPU 24 performs wireless communication via the wireless communication unit 23.

  When the power is turned on to the slave unit 2, the pairing mode is set, and the processing of the CPU 24 proceeds to step S41 and waits for reception of a command from the master unit 4. The slave unit 2 is always in the pairing mode when the power is turned on, and transitions to the normal connection mode when address registration is completed or a connect command is received.

  When the power is turned on to the master unit 4, the processing of the CPU 44 proceeds to step S31, reads the pairing instruction SW (search instruction means) 45, and determines whether the switch is turned on. If the switch is turned on when the power is turned on, the pairing mode is set, the process proceeds to step S32, and the pairing process is started. When the power is turned on with the switch turned off, the normal connection mode is set, the process proceeds to step S39, and the wireless communication process described in FIG. 2 is performed. In the pairing mode, in step S32, a search command is transmitted to search for surrounding wireless devices, and the process proceeds to step S33. In step S33, reception of a response to the search command is awaited.

  Next, the processing of the CPU 24 of the slave unit 2 proceeds to step S42 when a command is received in step S41. In step S42, it is determined whether the received command is a search command. If the received command is a search command, the process proceeds to step S44. If it is not a search command, the process proceeds to step S43 to determine whether it is a connect command. If it is a connect command, the process proceeds to step S49 to enter the normal connection mode, and the wireless communication process described with reference to FIG. 2 is performed. If it is not a connect command, the process returns to step S41 to wait for command reception again. When a search command is received and the process proceeds to step S44, a response command is transmitted. The response command is accompanied by a unique address that the slave unit 2 has. When the transmission is completed, the process proceeds to step S45.

  Next, the processing of the CPU 44 of the master unit 4 proceeds to step S34 when a response command is received in step S33. In step S33, as a flow (not shown), if a response command is not received even after a predetermined time has elapsed, the process proceeds to step S39 as a time-out process to enter the normal connection mode. In step S34, a connect command is transmitted based on the address of the slave unit 2 included in the response command, and communication is established with the slave unit 2 having the address. When communication is established, the process proceeds to step S35.

  Next, in step S45, the CPU 24 of the slave unit 2 receives a connect command from the master unit 4, transmits a connect OK command, and establishes communication. When communication is established, the process proceeds to step S46, where the switch number is read from the camera number setting SW 22 and the camera number is acquired. If a camera number is acquired, it will progress to step S47 and will transmit this camera number. When the transmission is completed, the process proceeds to step S48 and waits until the communication is disconnected.

  Next, the processing of the CPU 44 of the master unit 4 receives the camera number from the slave unit 2 in step S35, and proceeds to step S36. In step S36, the address of the slave unit 2 is registered (stored) in association with each other so that the received camera number matches the switch number (selected position) of the connection destination selection SW42. If registration is completed, it will progress to step S37 and communication will be cut | disconnected. When the communication is cut off, the process returns to step S32 again, and steps S32 to S37 are repeated to sequentially register the addresses of the other slave units.

Next, in step S48, when the communication is disconnected in step S48, the process of the CPU 24 of the slave unit 2 proceeds to step S49 to enter the normal connection mode, and performs the wireless communication process described in FIG. In the normal connection mode, the response is made only to the connect command, so that the slave unit for which address registration has been performed does not return a response command for the search command. Therefore, surrounding slave units with unregistered addresses are sequentially registered in the master unit 4, and when the address registration of all the slave units is completed, the master unit transitions to the normal connection mode by the time-out process in step S33.
The present invention can be applied to an imaging system including one or more slave units, and the configuration diagram of FIG. 4 shows a configuration example of an imaging system including a plurality of slave units.

  An imaging device (1 turtle) assigned camera number 1 is a slave unit 2a, an imaging device (2 turtles) assigned slave unit 2b, and an imaging device is assigned slave units 2b and 3 The slave unit 2c is connected to (3 turtles). The slave unit 2a is assigned a unique address of “1234”, 2b is “2345”, and 2c is “3456”. An example in which the master unit 4 is connected to the demand 3 and the addresses of the slave units 2a, 2b, and 2c are registered in the master unit 4 will be described.

  The camera number setting SW 22 of the slave unit 2a connected to one camera is set to 1 by the user. Similarly, No. 2 is set in the slave unit 2b and No. 3 is set in the slave unit 2c. When the power of all the slave units is turned on, and the power of the master unit 4 is turned on while turning on the pairing instruction SW 45 configured in the master unit 4, pairing processing is performed. In the pairing process, as described with reference to FIG. 3, the master unit 4 searches for peripheral slave units, and the address registration of the slave units 2a to 2c is automatically performed sequentially.

FIG. 5 shows a correspondence table between the registered addresses and the connection destination selection SW 42.
In the switch number (selection position) 1 of the connection destination selection SW 42, the address (“1234”) of the slave unit 2a connected to one camera is registered. Similarly, the address (“2345”) of the 2 turtle slave unit 2b is registered in the switch number 2 of the connection destination selection SW42, and the address (“3456”) of the 3 turtle slave unit 2c is registered in the switch number 3. The Therefore, if you select No. 1 in the connection destination selection SW 42, you will be connected to 1 turtle, 2 if you select 2, 2 turtles, if you select 3, you will be connected to 3 turtles. A device can be selected. Further, since the imaging device and the slave unit are easily connected, it is imagined that the combination of the imaging device and the slave unit is changed, or the number of slave units to be used is changed according to the imaging situation. Even in such a case, as described above, the user can easily perform address registration in a state where the switch number of the connection destination selection SW 42 and the camera number match as shown in FIG.

  Thus, in this embodiment, address registration by the user is easy, and by performing address registration in which the camera number and the selection number of the connection destination selection SW 42 match, a plurality of selectable connection destinations can be easily obtained. I can know.

  In this embodiment, the master unit 4 is in a pairing mode flow when the pairing instruction SW 45 is turned on when the power is turned on, but the present invention is not limited to this. For example, it may be configured to always start up in the pairing mode when the power is turned on, or when the power is turned on, it starts up in the normal connection mode, and when the pairing instruction SW45 is turned on, the flow may transit to the pairing mode. good.

  Further, the example in which the slave unit 2 enters the pairing mode when the power is turned on has been described. However, the switch number of the camera number setting SW22 is stored, and when the camera number setting SW22 is switched, the pairing mode is set. It may be a flow to start up.

  Furthermore, in this embodiment, the connection between the photographing device and the slave unit and the connection between the demand and the master unit are configured by serial communication. However, the present invention is not limited to this, and the command signal is transmitted by an analog signal. Is also good.

  Furthermore, although the example where the slave unit 2 and the master unit 4 are configured as independent wireless devices has been described, they may be incorporated in the photographing device 1 and the demand 3, respectively.

Hereinafter, with reference to FIGS. 6-7, the imaging | photography system by the 2nd Example of this invention is demonstrated.
FIG. 6 shows the configuration of an imaging system that is the second embodiment of the present invention. The components described with the same reference numerals as in FIG.

  The only difference in configuration from the first embodiment is that the camera number setting SW 22 of FIG. 1 is not configured. In the first embodiment, the example in which the camera number of the photographing apparatus 1 is set by the user using the camera number setting SW 22 has been described. In the second embodiment, an example will be described in which a camera number is set in advance in the photographing apparatus 1 and the slave unit 2 acquires the camera number from the photographing apparatus 1 via serial communication.

The flowchart of FIG. 7 shows the flow of pairing processing for registering the address of the slave unit 2 in the master unit 4. The CPU 24 and the CPU 44 control these processes according to a computer program stored in a memory (not shown). Since the processes described with the same reference numerals as in FIG. 3 are the same, the description thereof is omitted.
In step S50, the CPU 24 of the slave unit 2 acquires a camera number from the photographing apparatus 1 via serial communication.

  Therefore, in the second embodiment, when the camera number is set in the photographing apparatus 1 in advance, the camera number is automatically acquired from the photographing apparatus 1, so that the setting by the user is not necessary. Therefore, the user can register an address in which the camera number and the switch number of the connection destination selection SW 42 match only by starting up the master unit 4 in the pairing mode.

  Hereinafter, with reference to FIG. 8, a photographing system according to a third embodiment of the present invention will be described.

In the third embodiment, a pairing process using a tally lamp included in the photographing apparatus will be described. In television broadcasting, photography is performed using a plurality of photographing devices. Therefore, a television broadcasting photographing device may be a notification device that allows a performer or a photographer to recognize a photographing device that currently uses a video. Tally lamp). The tally lamp is used to indicate that the photographing apparatus is being used for television broadcasting, depending on whether the tally lamp is turned on / off or on (notification state).
The configuration of the photographing system according to the third embodiment of the present invention is the same as that shown in FIG.

The flowchart of FIG. 8 shows the flow of pairing processing for registering the address of the slave unit 2 in the master unit 4. The CPU 24 and the CPU 44 control these processes according to a computer program stored in a memory (not shown). Since the processes described with the same reference numerals as in FIG. 3 are the same, the description thereof is omitted.
Communication with the slave unit 2 that has returned a response command to the search command in the processes up to step S34 and step S45 is established.

  Next, in the processing of the CPU 24 of the slave unit 2, in step S70, the lighting of the tally lamp included in the photographing apparatus 1 is instructed via serial communication. In response to the instruction, the photographing apparatus 1 turns on the tally lamp (sets to a notification state).

Next, step S60 of the master unit 4 is a manual process by the user, confirms the camera number of the photographing apparatus whose tally lamp is lit, and sets the switch number of the connection destination selection SW 42 so as to match the camera number. Match. Then, the switch number is determined by turning on the pairing instruction SW45. When the switch number is determined, the process proceeds to step S61. In step S61, the address of the slave unit 2 with which communication has been established is registered in association with the switch number determined in step S60. When the registration of the address is completed, the communication is disconnected, and steps S32 to S37 are repeated again.
When the communication is disconnected, the processing of the CPU 24 of the slave unit 2 proceeds to step S71. In step S71, a command to turn off the tally lamp included in the photographing apparatus 1 is given via serial communication. In response to the instruction, the imaging device 1 turns off the tally lamp (releases the notification state).

  As described above, since the tally lamp of the photographing apparatus that has returned the response command to the search command at the time of the search by the search means is turned on, the user can recognize the photographing apparatus that is the target of address registration by the tally lamp. Therefore, the user can register the addresses sequentially by confirming the camera number of the photographing apparatus whose tally lamp is lit and setting the connection destination selection SW 42 switch. Therefore, the user can easily register an address in which the camera number shown in FIG. 5 and the switch number of the connection destination selection SW 42 coincide with each other only by operating the master unit 4.

In addition, although it illustrated about using a tally lamp as alerting | reporting information to a photographer, this invention is not limited to this, You may use the means to make a photographer recognize by another method.
In the above-described embodiment, the case where only one demand is considered has been illustrated, but the present invention can be similarly applied to a case where there are a plurality of demands.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary.
