Description

  The present invention relates to an imaging system, an imaging apparatus, and an information transmission apparatus.

  Conventionally, in order to illuminate the subject in three dimensions, wireless flash photography that emits a signal from a master flash built in or attached to the camera at the time of shooting and synchronously emits at least one slave flash arranged at a position away from the camera. Has been done.

  In wireless communication by flash emission, the master flash on the camera side emits light, the slave flash receives this flash light as signal light, and the slave flash that receives this signal light emits light with a predetermined light emission amount according to the signal light , Done by.

  A calculation unit provided in the camera body performs a calculation related to the light emission amount of the slave flash. The light emission amount data calculated by the camera body is sent to the slave flash by the signal light emitted from the master flash.

  At this time, the same channel is set between the master flash and the slave flash so as not to malfunction due to other signal light. The master flash emits channel identification start signal light before emitting signal light. The slave flash receives the channel identification start signal light. If the channel is the same channel as the channel that is identified and set as the slave flash, the slave flash receives the subsequent signal light and emits light with a predetermined light emission amount according to the signal light. To do. Thus, the master flash and slave flash must be set to the same channel.

  The channel is set first for the slave flash channel. Also, setting is made with the operation member of the slave flash, such as setting of the guide number of the flash.

  Next, a slave flash is attached to the camera with a master flash, and the camera obtains channel information, guide number information, etc. set via contacts, and sets the master flash channel and guide number. .

  Such a wireless flash photographing system is disclosed in Patent Document 1, for example. (For example, refer to Patent Document 1).

  Similarly, peripheral devices that communicate with the camera wirelessly include remote controllers and metering meters. Before starting wireless communication, set the channel on the peripheral device and set the same channel on the camera side. There was a need.

  On the other hand, human body communication has been proposed in which data communication between two different devices is performed via a human body.

  In human body communication, a human body is used instead of a cable, and a signal is transmitted by a change in the current flowing through the human body. Therefore, there is an advantage that there is no need to use a cable compared to wired communication using cables. In addition, since the transmission distance is short compared to the case of wireless transmission, signals can be transmitted with less power consumption, and the circuit scale can be reduced.

For example, a method has been proposed in which a measuring instrument for measuring a pulse, a heart rate, etc. in training is worn on the ear, and data is exchanged with a display means such as a wrist watch worn on the arm via the human body (for example, , See Patent Document 2). In addition, a method has been proposed in which data is transmitted via a human body by wearing a transmitter shaped like a wristwatch and swinging to a terminal equipped with a receiver (see, for example, Patent Document 3). Furthermore, a method of performing data communication using another high-speed communication means after specifying a partner device by performing communication via a human body and specifying a partner to communicate with is proposed (for example, Patent Documents). 4).

  FIG. 17A is a flowchart for explaining a general procedure for transmitting setting information by the peripheral device according to the embodiment of the present invention. FIG. 17B is a flowchart illustrating a transmission procedure of an information transmission routine that is a subroutine that is activated when the peripheral device transmits setting information.

  In the present embodiment, the human body communication transmission control unit 325 can monitor the state of the communication monitoring switch 302 at regular time intervals using an internal timer, and can receive a transmission signal via the human body when the communication monitoring switch 302 is turned on. Then, communication shall be started.

  In step S100 of FIG. 17A, it is assumed that the human body communication transmission control unit 325 detects that the communication start switch 302 is ON (step S100). The human body communication transmission control unit 325 activates an information transmission routine which is a subroutine (step S101). When the information transmission routine ends, the transmission of the setting information is completed.

  Next, an outline procedure of the information transmission routine will be described with reference to FIG.

  When the information transmission routine starts, the human body communication transmission control unit 325 turns on a power supply (not shown) of the transmission unit 300 and transmits a data transmission start signal including information on peripheral devices and information on the number N of setting information via the human body. (Step S102). When the peripheral device is the flash 5, the setting information includes channel setting information, guide number setting information, device information, and the like, and each data is transmitted as 2-byte data. In order to identify each data, a unique number N is assigned in the order of transmission. For example, data 1 is channel setting information, data 2 is guide number setting information, and data 3 is device information.

  In step S103, the human body communication transmission control unit 325 reads the data 1 in the flash RAM 322 as the first internal storage unit, and transmits the modulated signal from the transmission unit 300 via the human body (step S103). Until the step S104, data 2 to N are sequentially transmitted (step S104).

  When the transmission to the data N is completed, the human body communication transmission control unit 325 transmits a data transmission end signal (step S105). This completes the transmission of data 1 to N, returns to the main routine, and ends.

  In the present embodiment, the communication start switch 303 is provided, and data is transmitted when the communication start switch 303 is ON. However, the communication start switch 303 is omitted, and step S101 is omitted, and data is always repeated. You may make it transmit.

  FIG. 18 is a flowchart illustrating an outline procedure of data reception performed by the imaging apparatus 10 according to the embodiment of the present invention. At this time, for example, the operator holds the grip portion 205 of the imaging apparatus 10 with the right hand and is in a state where the finger is touching the electrode A 301, and the other hand is the flash 5 or the remote controller 6 as a peripheral device. Alternatively, it is assumed that the metering meter 7 or the information transmission device 8 is held and the communication start switch 303 is pressed. In the present embodiment, the main microcomputer unit 79 monitors the state of the shutter button 112 at regular time intervals by an internal timer, and when the shutter button 112 is half-pressed (SW1 181 ON), transmission via the human body. The signal can be received and communication is started.

  In step S301, it is assumed that the human body communication reception control unit 73 detects that the shutter button 61 is half-pressed (SW1 181 ON). The human body communication reception control unit 73 activates an information reception routine which will be described in detail later (step S302). When the information receiving routine is executed, the RAM 75 stores peripheral device setting information. In the case of the flash 5, the setting information is channel setting information, guide number information, and device information.

  In the case of the remote controller 6 and the metering meter 7, it is channel setting information, guide number information, and device information. The device information is unique information indicating each peripheral device such as the flash 5, and the channel setting information is stored in a predetermined location in the RAM 75 for each device. In the case of the information transmission device 8, setting information of peripheral devices other than the information transmission device 8 is transmitted.

  The wireless communication control unit 71 reads channel setting information for each peripheral device stored in the RAM 75, and sets a wireless communication channel for each peripheral device (step S303). This completes information reception via the human body. The main microcomputer unit 79 performs predetermined control based on the setting information received thereafter.

  In this embodiment, when the operator presses the shutter button 61 halfway (SW1 181 ON), the reception unit 200 starts reception. However, the operation member that starts reception is the shutter button 61. It is not limited, and other switches and buttons may be used. Further, the electrode C201 may be formed on the surface of an operation member such as the shutter button 61. Furthermore, the reception unit 200 may always receive regardless of the operation of the switch or button.

  In step S350 of FIG. 19, the human body communication reception control unit 73 determines whether or not the reception switch 503 is ON (step S350). When the reception switch 503 is ON (step S350; Yes), the information reception routine is started (step S302), and when the process is completed, the process returns to step S350.

When the reception switch 503 is OFF (step S350; No), the human body communication transmission control unit 325 determines whether the communication start switch 303 is ON (step S351). When the communication start switch 303 is ON (step S351; Yes), the information transmission routine is started (step S101), and when the process is completed, the process returns to step S350. When the communication start switch 303 is OFF (step S351; No), the process returns to step S350.

Next, the variable M is acquired (step S402), and it is determined whether M = 3. (Step S403). When M <3, that is, when the number of reception failures is less than 3, the process proceeds to step S405 (step S403; No).

  When the information transmission start signal cannot be received within the predetermined time (step S405; No), M = M + 1 is set, and the process returns to step S402 (step S413).

  When the information transmission start signal is received within the predetermined time (step S405; Yes), the information of the type and number of information included in the information transmission start signal is obtained and data 1 is received (step S406). Data 1 is, for example, channel setting information.

  When the data 1 cannot be received within the predetermined time (step S407; No), M = M + 1 is set, and the process returns to step S402 (step S413).

  When the data 1 can be received within the predetermined time (step S407; Yes), the received data, that is, the data 1 is stored in the RAM 75 (step S408).

  Similarly, data N is received in the same procedure and stored in the RAM 75.

  Data N is received (step S409), and when data N cannot be received within a predetermined time (step S410; No), M = M + 1 is set, and the process returns to step S402 (step S413).

  When the data N can be received within the predetermined time (step S410; Yes), the received data is stored in the RAM 75 in order (step S411).

  Next, a data end signal is received (step S412). When the data end signal cannot be received within the predetermined time (step S414; No), M = M + 1 is set, and the process returns to step S402 (step S413).

  When the data end signal can be received within the predetermined time (step S414; Yes), the process is terminated and the process returns to the original main routine. At this time, the main microcomputer unit 79 receives all the data 1 to N as the setting information, and each information is stored in the RAM 75 as the second storage means.

  In step S403, when M = 3, that is, when reception fails three times (step S403; Yes), it is determined that reception is impossible, and the main microcomputer unit 79 performs error processing (step S404). For example, the main microcomputer unit 79 records information indicating that reception is impossible in a predetermined location of the RAM 75 as error processing.

  As described above, according to the present embodiment, when a person touches the peripheral device and the camera, the setting information of the peripheral device can be transmitted to the camera body and the setting on the camera side can be performed. An imaging system can be provided.
