Embodiments of a lighting device, a camera, and a camera system according to the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of a camera system 10 according to the present embodiment. The camera system 10 of this embodiment includes a camera 30 and a lighting device 20 that can be attached to and detached from the camera 30.

  As illustrated, the illumination device 20 includes a light emitting unit 21 including a protector, a xenon tube, a reflector, and the like (not illustrated) therein, a light receiving unit 22 that receives subject light when the light emitting unit 21 emits light, And an MCU 23 for controlling the respective units. Although not shown, the light emitting unit 21 is connected with a capacitor, a charge control circuit, and a flash circuit.

  The lighting device 20 includes a memory 24, a communication unit 25, a lighting side operation unit 26, and a liquid crystal monitor 27. In the memory 24, in addition to a program for controlling the MCU 23, data necessary for executing this program, information on the light emission function that can be set in its own lighting device 20, and information on the light emission function input from the illumination side operation unit 26 The setting information, the setting information of the light emitting function to be set by the lighting device 20 of itself is stored. In addition, data necessary for the MCU 23 to execute arithmetic processing is temporarily stored.

  The communication unit 25 is a communication unit for performing wireless communication with the camera 30. The illumination-side operation unit 26 includes an operation member for inputting information on a light emission function that can be set for the illumination device 20. The liquid crystal monitor 27 is a display unit for displaying the light emission function setting information input from the illumination side operation unit 26 and the light emission function setting information to be set by the lighting device 20 received from the camera 30.

  Here, the specific example of the illumination side operation part 26 is demonstrated easily. FIG. 2 is an external view of the illumination device 20 when viewed from the back. A liquid crystal monitor 27 is disposed in the center of the back surface of the lighting device 20. Below that, various dials and buttons are arranged as the illumination side operation unit 26. The photographer can input information on the light emitting function by operating the selector dial 26a, the OK button 26b, the mode button 26c, and the function button 26d. In this case, the photographer presses the mode button 26c or the function button 26d to display icons or setting values (not shown) on the liquid crystal monitor 27, and then turns the selector dial 26a to change the desired light emission mode or dimming correction. By selecting an amount or the like and pressing the OK button 26b, the selected content can be input.

  Further, as will be described later, in this embodiment, the photographer can input information on the light emitting function in the illumination device 20 from the camera 30. Further, the photographer can directly change the content of the light emitting function with respect to the illumination device 20, and in this case, information regarding the content change of the input setting information is sent to the camera 30 via the communication unit 25.

Control is performed to set the light emission function setting information to be set. The MCU 23 controls the light emitting operation of the light emitting unit 21 based on the set setting information. Note that the setting information of the set light emission function is stored in the memory 24. Then, when the lighting device 20 and the camera 30 cannot communicate, or after the lighting device 20 is turned off, the lighting device 20 and the camera 30 can communicate again. The information is read from the memory 24 and transmitted to the camera 30 as setting information of the light emitting function in the lighting device 20.

  In addition, when the illumination device 20 becomes communicable with the camera 30, the MCU 23 responds to the model confirmation signal from the camera 30 and uses the light emitting function information input from the camera 30 as setting information. Control is performed to transmit a model information signal indicating whether or not the lighting device can be set from the communication unit 25 to the camera 30. In response to the function confirmation signal from the camera 30, the MCU 23 sends information on the light emitting function that can be set by itself (settable mode, upper limit value, lower limit value, etc.) from the communication unit 25 to the camera 30. Control to transmit.

  On the other hand, the camera 30 includes an imaging unit 31 on which subject light is incident, an image data processing unit 32 that performs various processes on the image signal output from the imaging unit 31, and a recording unit 33 that records the processed image signal.

  The recording unit 33 records the image signal subjected to various processes by the image data processing unit 32 on a recording medium such as a CF card or an SD card (not shown).

  The camera side operation unit 35 is an input means for the photographer to perform various operations, and includes a release switch for starting shooting, an operation member for inputting setting information of the light emitting function of the lighting device 20 that is a communication destination, and the like. It is configured. Here, a specific example of the camera side operation unit 35 will be described. FIG. 3 is an external view of the camera 30 as viewed from the back. A dot display type liquid crystal monitor 38 capable of displaying arbitrary information, which will be described later, is disposed on the back of the camera 30, and various dials and buttons that serve as the camera side operation unit 35 are disposed on the right side thereof. Yes. In addition to displaying various types of shooting information related to the setting contents of the camera 30, the liquid crystal monitor 38 displays an image in which a through image captured by the imaging unit 31 has been captured (a captured image recorded on a recording medium by the recording unit 33 is displayed). It is also possible to display read-out reproduced images) and information on the function of the lighting device described later. The dot display type liquid crystal monitor 38 is not particularly limited in the contents that can be displayed, and the degree of freedom with respect to the display contents is relatively large. In the present embodiment, the photographer can input information on the light emitting function of the illumination device 20 by operating the selector dial 35a, the OK button 35b, and a function button (not shown). Since the method of input operation is the same as that of the illumination side operation unit 26, description thereof is omitted.

  In addition to the master lighting device, FIG. 3 shows a display form example in the case where three remote lighting devices can be controlled. That is, on the liquid crystal monitor 38, the setting states of the master lighting device (M), the remote lighting device (A), the remote lighting device (B), and the remote lighting device (C) are displayed in order from the top of the screen. The master lighting device is a lighting device directly attached to the camera 30 or a lighting device connected to the camera 30 via a dedicated light control cord. The remote lighting device is a lighting device that is disposed at a position away from the camera 30 and is wirelessly controlled.

  In the liquid crystal monitor 38, “TTL” indicates TTL light control, “aperture icon + A” indicates external automatic light control, and “M” indicates manual light emission as light emission modes. Further, as the light adjustment correction value, + O. Numerical values from 3 EV to -0.7 EV are shown. “Ch1” in the upper right corner indicates a channel (number) for communication. Further, the lower part shows the focal length “24 mm” and the F value “F5.6” of the taking lens. The camera 30 can input light emission function information to both the master lighting device and the remote lighting device.

The camera 30 includes a memory 36, a communication unit 37, a liquid crystal monitor 38, and a lighting device detection unit 39. In the memory 36, various setting information input by the photographer, a program for controlling the MCU 34, data necessary for executing this program, and each lighting device 20 (M ), 20 (A) to 20 (C) (hereinafter also referred to as “each lighting device 20”), and information on the light emitting function received from each lighting device 20 (A) to 20 (C). And information related to the content change of the setting information. In addition, data necessary for the MCU 34 to execute arithmetic processing, an image signal captured by the imaging unit 31, and the like are temporarily stored. The communication unit 37 is a communication unit for performing wireless communication with each lighting device 20 (M), 20 (A) to 20 (C). In the present embodiment, the camera 30 is described as performing information communication with the master lighting device 20 (M) by wireless communication. However, the master lighting device 20 (M) is attached to the hot shoe of the camera 30. In some cases, when the hot shoe has an electrical contact capable of communicating information with the lighting device, information communication may be performed via the electrical contact.
The liquid crystal monitor 38 is a display unit for displaying information on the light emitting function of each lighting device 20 received from the lighting device 20, setting information on the light emitting function of the lighting device 20 input from the camera side operation unit 35, and the like. . The illumination device detection unit 39 is for detecting whether or not each illumination device 20 (M), 20 (A) to 20 (C) is in a state where communication with the camera 30 is possible.

  When the photographer presses a release button (not shown) of the camera-side operation unit 35 halfway and the execution signal of the autofocus (AF) operation is transmitted, the MCU 34 automatically based on the output of the imaging unit 31. AF control for focusing on a main subject and AE (automatic exposure) control for automatically adjusting exposure are performed. Then, when a photographing start signal is transmitted by the photographer fully pressing the release button, a diaphragm mechanism or a shutter (not shown) is driven at a predetermined timing, and control for causing the imaging unit 31 to image subject light is performed. It is carried out.

  Further, the MCU 34 displays information on the light emitting function of the lighting device 20 received from each of the lighting devices 20 (M) and 20 (A) to 20 (C) on the liquid crystal monitor 38 in a state where the MCU 34 can communicate with the lighting device 20. At the same time, control is performed to transmit information on the light emitting function input through the camera side operation unit 35 to each lighting device 20 as setting information on the light emitting function to be set on each lighting device 20. Further, when the MCU 34 receives information related to the content change of the setting information from each lighting device 20, the MCU 34 performs control to update the display content displayed on the liquid crystal monitor 38 based on the information. As described above, in the camera system 10 of the present embodiment, the information on the light emitting function input through the camera side operation unit 35 is set as the setting information of each lighting device 20 (M), 20 (A) to 20 (C). Can do. In addition, the display content on the camera 30 side can be updated in conjunction with the change in the content of the light emitting function information input on each lighting device 20 side. That is, in this embodiment, since the setting information of the light emission function of each lighting device 20 can be input bidirectionally between each lighting device 20 and the camera 30, the photographer can set the camera 30 side or each lighting device 20 side. The setting of the light emission function can be changed on either side. For example, when three remote lighting devices (A) to (C) are connected as shown in FIG. 3, only the item of the remote lighting device whose display contents are updated is changed.

  Note that the MCU 34 of the camera 30 has received an operation input for invalidating the content change of the setting information transmitted from each of the lighting devices 20 (M) and 20 (A) to 20 (C) by the camera side operation unit 35. When the content change information is received from each lighting device 20, the display content displayed on the liquid crystal monitor 38 is not updated. In other words, even when the photographer directly inputs the content change of the light emitting function to each lighting device 20, the operation for invalidating the content change of the setting information transmitted from each lighting device 20 as described above If an input has been made, priority is given to the setting information of the light emitting function input on the camera 30 side.

  Further, the MCU 34 performs control to end the information display of the light emitting function on the liquid crystal monitor 38 when the lighting device detection unit 39 detects that each lighting device 20 is not in a state where it can communicate with the camera 30. . At this time, a message such as “Remote lighting device A has been removed” may be displayed on the liquid crystal monitor 27. Moreover, when detecting the communication state between each illuminating device 20 and the camera 30 by the illuminating device detection unit 39, a time lag of about several hundred msec to about 1 second may be provided in order to avoid malfunction. In other words, even if the lighting device 20 and the camera 30 are temporarily unable to communicate, the information display of the light emitting function is not immediately terminated.

  In addition, the MCU 34 emits light from each lighting device 20 that is previously input through the camera-side operation unit 35 when the lighting device 20 (M) and 20 (A) to 20 (C) can communicate with each lighting device 20. When there is information on the function, control is performed to read the information on the light emitting function from the memory 36 and transmit the information to the lighting devices 20 via the communication unit 37. That is, even when the camera 30 is not communicable with each lighting device 20, the photographer can make a reservation setting for the camera 30 with information on the light emitting function of each lighting device 20. At this time, a message such as “can be reserved” may be displayed on the liquid crystal monitor 38.

  FIG. 4 is a plan view showing a specific arrangement example of the camera system 10. As shown in FIG. 4, a master illumination device 20 </ b> M is attached to the camera 30, and remote illumination devices 20 </ b> A and 20 </ b> B are arranged at positions away from the camera 30. The master lighting device 20M and the remote lighting devices 20A and 20B are arranged so as to emit illumination light from three directions toward the subject 40. As described above, the lighting device 20 of the present embodiment can be set to either a master lighting device or a remote lighting device. When the lighting device 20 of the present embodiment is set as the master lighting device 20M and attached to the camera 30, communication between the remote lighting devices 20A and 20B and the camera 30 is performed via the communication unit 25 of the master lighting device 20M. Will be done. In this case, the master lighting device 20M functions as a communication device that can be attached to and detached from the camera 30. In addition to the master lighting device 20M, communication between the remote lighting devices 20A and 20B and the camera 30 can be performed via a dedicated communication device that is detachable from the camera 30.

  Further, when the master illumination device 20M is not attached to the camera 30, communication can be performed directly with the communication unit 37 of the camera 30 via the communication unit 25 of the remote illumination devices 20A and 20B. Also in this case, information on the light emitting function in each of the remote lighting devices 20A and 20B can be input from the camera 30 side. Note that the number of remote lighting devices that can communicate with the camera 30 (or via the master lighting device 20M) is not limited to the example of the present embodiment, and may be larger.

  Next, in the camera system 10 configured as described above, a processing procedure when setting the light emitting function of the lighting device 20 set as the remote lighting device from the camera 30 will be described with reference to the flowchart shown in FIG. In FIG. 5, the left side shows a flowchart of the camera 30, and the right side shows a flowchart of the lighting device 20.

  First, the MCU 34 of the camera 30 transmits a model confirmation signal to the illumination device 20 when the illumination device detection unit 39 detects that communication with the illumination device 20 is possible (S101). (S102). This model confirmation signal is for confirming whether or not the illumination device 20 is a model capable of transmitting information on the light emitting function from the camera side. On the other hand, when the MCU 23 of the lighting device 20 receives the model confirmation signal from the camera 30 (S201), the lighting device can itself set the light emitting function information input from the camera 30 as setting information to the camera 30. Is transmitted to the camera 30 (S202).

  Subsequently, when receiving the model notification signal from the lighting device 20, the MCU 34 of the camera 30 transmits a function confirmation signal to the lighting device 20 (S104). This function confirmation signal is for confirming what light emitting function the illumination device 20 has. When the MCU 23 of the lighting device 20 receives the function confirmation signal from the camera 30 (S203), the MCU 34 of the camera 30 transmits the information on the light emitting function that can be set to the camera 30 (S204). Information on the light emitting function that can be set by the lighting device 20 is received (S105).

  Next, the MCU 34 of the camera 30 displays information related to the light emission function of the illumination device 20 on the liquid crystal monitor 38 as shown in FIG. 3, for example, based on the received information on the light emission function that can be set by the illumination device 20 (S106). ). And the information input of the light emission function of the illuminating device 20 by a photographer is acquired (S107). The photographer can input information on the light emitting function by operating, for example, a selector dial 35a, an OK button 35b, and a function button (not shown) as shown in FIG. The MCU 34 of the camera 30 transmits the input information on the light emission function to the lighting device 20 when the information input of the light emission function by the photographer is completed (S108).

  If there is information on the light emitting function of the lighting device 20 that has been input in advance through the camera side operation unit 35, the information on the light emitting function is read from the memory 36 following step S106, and is transmitted via the communication unit 37. It is transmitted to the lighting device 20. Here, when the information on the light emitting function that has been input in advance does not match the information on the light emitting function of the lighting device 20 that has actually become communicable, only the information on the light emitting function that can be set by the lighting device 20 is used. Is selected and sent to the lighting device 20.

  On the other hand, when the MCU 23 of the lighting device 20 receives the light emitting function information from the camera 30 (S205), the light emitting function information is set as setting information of the light emitting function to be set in its own lighting device 20, and the memory 24 (S206). Subsequently, the MCU 23 of the lighting device 20 displays the set light emission function setting information on the liquid crystal monitor 27 (S207). Thereafter, the MCU 23 of the illuminating device 20 controls the light emission operation of the light emitting unit 21 based on the set light emission function setting information.

According to the said embodiment, there exist the following effects.
(1) Since the display related to the function setting of the lighting device is performed using a dot display type display device set on the back of the camera and capable of detailed display, the display device on the lighting device side is complicated. It is possible to realize a complicated display relating to the function of the lighting device or a complicated display switching without incurring a cost increase.
(2) When setting and inputting information to be set in the illumination device, the illumination device is configured so that an input operation can be performed with the operation unit 35 on the camera side while confirming the set input content on the display device on the camera side. When the camera is a dedicated accessory for the camera according to the present invention, the operation member to be operated by the user to set the illumination conditions can be omitted from the illumination device side, and the illumination device can be further downsized. And cost reduction.
(3) Since the display content on the camera side is updated in conjunction with the content change of the light emitting function information input on the lighting device side, the photographer emits light on either the camera side or the lighting device side. Function settings can be changed.
(4) When a predetermined operation input is made on the camera side, it is possible to prevent the display content to be displayed on the liquid crystal monitor from being updated even if information on changing the content of the setting information is received from the lighting device. Even if the photographer inadvertently touches the button of the lighting device when changing the position of the lighting device, the setting information of the light emitting function is not changed to an unintended content. Therefore, the photographer can move the lighting device without paying attention to the buttons of the lighting device, and even if the button of the lighting device is touched, the light emitting function of the lighting device is not reset, You can continue shooting.
(5) When it is detected that the lighting device is not communicable with the camera, the information display of the light emitting function on the liquid crystal monitor of the camera is terminated, so that the photographer can communicate with the camera. It can be easily recognized that it is not in a state. Further, battery consumption on the camera side for driving the liquid crystal monitor can be suppressed.
(6) Even when the master lighting device 20M is not attached to the camera, it is directly connected to the communication unit 37 of the camera 30 via the communication unit 25 of the remote lighting devices 20A and 20B (without using the master lighting device). Ii) because it is possible to communicate, a remote lighting system can be realized even if a master lighting device is not provided. For this reason, even if two illumination devices are not prepared, remote illumination photography can be performed using only a camera and one illumination device, and the user convenience is good.
(Deformation)

Without being limited to the embodiment described above, the present invention can be variously modified and changed as described below, and these are also within the scope of the present invention.
(1) When the lighting device is mounted on the camera, a model information signal is sent from the lighting device to the camera to notify that the lighting device is capable of setting the light emitting function information input from the camera as setting information. You may control to transmit automatically.
(2) Generally, since the liquid crystal monitor of the camera is a dot display type, detailed information display can be performed on the camera side even if the liquid crystal monitor of the illumination device is a segment display type. For this reason, for example, functions that have been added due to firmware upgrades that cannot be displayed on the liquid crystal monitor of the illumination device can be displayed on the liquid crystal monitor on the camera side. Further, when the illumination device is a dedicated product for the camera according to the present invention, the liquid crystal monitor on the illumination device side can be omitted. According to this, since the liquid crystal monitor, the monitor driving driver, the memory, the operation member, and the like can be reduced or simplified, the cost can be reduced.

  Moreover, although the said embodiment and modification can be used in combination suitably, since the structure of each embodiment is clear by illustration and description, detailed description is abbreviate | omitted. Furthermore, the present invention is not limited by the embodiment described above.
