Description

  The present invention relates to an imaging system, and more particularly to an imaging system that simultaneously drives a plurality of lens devices.

  2. Description of the Related Art Conventionally, a lens demand used for television broadcasting or the like uses a zoom demand or a focus demand that enables a zoom or focus servo drive operation from a remote location. These demands are equipped with various functions, and are equipped with a switch that directs the operation of the shot function (hereinafter referred to as a shot switch) and a switch that instructs ON / OFF of the vibration isolation function (hereinafter referred to as an anti-vibration switch). It has been.

  The lens apparatus and the demand are connected by serial communication, and the zoom and focus servo drive or the shot function can be operated by bidirectionally transmitting and receiving control commands. A control command transmitted from the demand is referred to as a command command, and a control command transmitted from the lens apparatus corresponding to the command command is referred to as a send back command.

  The shot function is a function that can store the lens position in the demand in advance and drive the lens from the arbitrary position to the stored lens position by pressing a switch. FIG. 8 is a diagram illustrating a sequence of control commands between the lens device of the shot function and the demand. First, in S801, when the demand detects that the shot switch has been pressed, the lens position stored in advance (hereinafter, shot position) is transmitted as a command command to the lens apparatus (S811). In S812, upon receiving the shot position command command, the lens apparatus holds the shot position and transmits the current lens position to the demand as a return command.

  In step S821, the demand transmits a preset speed (for example, the highest speed) to the lens apparatus as a command command. In S822, the lens apparatus drives the lens toward the shot position based on the received speed command, and transmits the current lens position to the demand as a return command. The transmission / reception of the control commands in S821 and S822 is repeated until the lens reaches the shot position. When the lens reaches the shot position, the lens apparatus transmits a shot completion return command to the demand in S832, in response to the speed command command transmitted in S831. Upon receiving the shot completion, the demand ends a series of shot functions.

  FIG. 9 is a diagram illustrating a control command sequence between the lens apparatus and the demand when the image stabilization switch is operated. First, in S901, when the demand detects that the image stabilization switch has been pressed, a command command for image stabilization ON is transmitted to the lens device (S911). In step S912, when the lens apparatus receives the image stabilization ON, the lens apparatus activates the image stabilization function of the lens apparatus, and transmits the image stabilization ON as a return command to the demand. When the demand receives anti-vibration ON as a send back command, the LED is turned on to clearly indicate to the user that the anti-vibration function is effective.

  Further, in S902, when it is detected that the image stabilization switch has been pressed while the image stabilization function is enabled, the demand transmits image stabilization OFF as a command command to the lens apparatus (S921). When receiving the image stabilization OFF, the lens device invalidates the image stabilization function of the lens device, and transmits the image stabilization OFF to the demand as a return command (S922). When the demand receives anti-vibration OFF as a send back command, the LED turns off the LED and clearly indicates to the user that the anti-vibration function is invalid.

  In addition, if the lens apparatus is not equipped with an image stabilization function, the lens apparatus transmits a vibration isolation OFF return command even if an image stabilization ON command command is received from the demand. Therefore, the validity / invalidity of the image stabilization function and the lighting / extinguishing of the LED are always matched.

  Furthermore, in recent years, there have been many disclosures of photographing systems using compound eye lenses for photographing stereoscopic images.

  For example, in Patent Document 1, of the two zoom lenses arranged in a pair on the left and right, the first zoom lens is directly driven according to the operation of the smooth switch, while the second zoom lens is photographed by the first zoom lens. A drive device that drives to match the magnification is disclosed.

  Further, in Patent Document 2, a lens controller that can eliminate an operation shift for each operation direction between the left and right lens devices by correcting and storing the operation states of the drive mechanisms of the two lens devices for each operation direction. Demand).

Japanese Patent No. 3278667 JP-A-8-223607

  However, in the prior art disclosed in the above-mentioned patent document, in order to construct a photographing system for photographing a stereoscopic video, a dedicated lens device or a demand is required, and it is easy to construct a stereoscopic video photographing system. There wasn't.

  In order to use the existing lens device and demand, the serial signal line for transmitting the command command may be branched into two and respectively connected to the two lens devices. However, since only one serial signal line for receiving a return command from the lens apparatus is provided in the existing demand, it can be connected to only one of the lens apparatuses. Therefore, as described above, there is a problem that a function that performs processing by using a return command such as ON / OFF of a shot function or a lens mounting function does not operate normally.

  Specifically, for example, in the shot function, the timing at which the shot operation is completed may differ between both lens apparatuses. In this case, if a shot completion return command transmitted by the lens apparatus completed earlier is transmitted to the demand, the demand terminates the shot function and does not transmit a command command for the speed command. Therefore, the other lens device in which the shot operation is not completed has a problem that the shot operation is interrupted and the lens stops before reaching the shot position. In addition, for example, in the ON / OFF operation of the image stabilization function, there is a case where a stereoscopic video shooting system is constructed by using lens devices having different function mounting and non-mounting functions in both lens devices. In this case, when a command command for turning on the image stabilization function is transmitted from the demand, the image stabilization function is enabled in the lens device equipped with the image stabilization function, and the image stabilization function is disabled in the lens device not equipped with the image stabilization function. Therefore, there is a problem that a difference occurs in the images obtained by both lens devices.

  Accordingly, an object of the present invention is to make it easy to use an existing lens device and a demand for a photographing system that drives a plurality of lens devices with one demand, and to further operate functions mounted on the demand normally. It is to provide a photographing system that enables it.

In order to achieve the above object, the present invention is an imaging system for simultaneously driving a plurality of lens devices by one operating member,
Serial communication means for transmitting and receiving serial communication with the operating member and the plurality of lens devices;
Command signal generating means for generating command signals to be transmitted to the plurality of lens devices, respectively, according to a command signal received from the operation member;
A return signal generating means for generating a return signal to be transmitted to the operation member by a return signal received from each of the plurality of lens devices;
An alignment state determination means for determining an alignment state between the plurality of lens devices or between the lens device and the operation member based on the return signal;
Based on the result of the matching state determination unit, the command signal generation unit and the return signal generation unit generate the command signal and the return signal.

  According to the present invention, an imaging system for driving a plurality of lens devices with one demand is facilitated by using an existing lens device and a demand, and further, functions mounted on the demand can be normally operated. An imaging system can be provided.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a configuration diagram of a photographing system according to an embodiment of the present invention.

[Example 1]
The imaging system according to the first embodiment of the present invention will be described below with reference to FIGS.

  FIG. 1 shows a configuration of an existing lens apparatus according to a first embodiment of the present invention and a stereoscopic video shooting system using a demand. The photographing system includes a first lens device 1 (hereinafter referred to as a lens device 1), a camera 5 to which the lens device 1 is attached, a second lens device 2 (hereinafter referred to as a lens device 2), and the lens device 2 attached thereto. The camera 6 is configured. Two photographed images obtained by the photographing device including these two lens devices and a camera are displayed on a monitor after being synthesized by, for example, a video mixer, and the monitor image is viewed through dedicated glasses. A stereoscopic image can be observed. The photographing device is not a dedicated device for stereoscopic video photography, but is constituted by a photographing device that performs normal 2D photographing. The photographing system includes a demand 3 for instructing driving of the lens device 1 and the lens device 2, and a matching device 4 connected to each of the lens device 1, the lens device 2, and the demand 3 by serial communication. .

  The lens device 1 and the lens device 2 incorporate an optical system that includes a movable optical member such as a focus lens, a zoom lens, and an iris (not shown). Further, the camera 5 and the camera 6 incorporate an image pickup device composed of a CCD sensor, a CMOS sensor, etc. (not shown). In this embodiment, a description will be given of an imaging device in which the lens device is detachable (replaceable) with respect to the camera. However, an imaging device in which the lens device and the camera are integrated may be used. The lens device 1 and the lens device 2 receive a command command for instructing driving of the movable optical member through serial communication, and drive the movable optical member.

  The demand 3 has an operation unit operated by a user (not shown), and commands driving of the movable optical member of the lens device 1 and the lens device 2 according to the operation direction and the operation amount of the operation unit. A command command is generated, and the command command is transmitted by serial communication. In addition, a switch (hereinafter referred to as a shot switch) for instructing an operation of a shot function (not shown) and a switch (hereinafter referred to as an anti-vibration switch) for instructing ON / OFF of an anti-vibration function are provided, and the switch is pressed. Thus, a command command corresponding to each function is transmitted.

  The matching device 4 has a CUP 41. The CPU 41 receives a command command transmitted from the demand 3, and transmits the command command to the lens device 1 and the lens device 2, respectively. Furthermore, the sending back command transmitted from the lens apparatus 1 and the lens apparatus 2 is received, respectively, and when the contents of the sending back command are different, the sending back command to be sent to the demand 3 is selected. Further, the control command is transmitted so as to correct the mismatch between the lens apparatuses or between the lens apparatus and the demand.

  FIG. 2 is a diagram illustrating a sequence of control commands for driving the lens device 1 and the movable optical member of the lens device 2 by operating the operation unit of the demand 3. In this figure, a zoom lens will be described as an example of the movable optical member.

  First, in S201, the demand 3 takes in the operation amount of the operation unit, and generates a speed command value for driving the zoom lens according to the operation amount. In S211, the demand 3 transmits the generated speed command value to the matching device 4. In S212, when receiving the speed command value, the matching device 4 transmits the speed command value to each of the lens device 1 and the lens device 2. When the lens device 1 and the lens device 2 receive the speed command value, the lens device 1 and the lens device 2 generate a drive signal from the speed command value and drive the respective zoom lenses. In S214, the lens device 1 transmits the zoom lens position of the current lens device 1 to the matching device 4 as a return command for the speed command value received in S212.

  Similarly, in S215, the lens apparatus 2 transmits the current zoom lens position of the lens apparatus 2 to the alignment apparatus 4. When the matching device 4 receives S214 and S215 which are return commands of the lens device 1 and the lens device 2, the matching device 4 selects a return command to be transmitted to the demand 3 according to the contents of the respective return commands. In the case of the control command example described with reference to FIG. 2, since the return commands of the lens device 1 and the lens device 2 are the same, either the lens device 1 or the lens device 2 is selected, and the demand 3 is directly selected. (S216). As described above, by repeating S201 to S216, when the operation unit of the demand 3 is operated, the lens device 1 and the zoom lens of the lens device 2 can be similarly driven accordingly.

  In addition, although an example in which a speed command is transmitted to the lens device based on the operation amount of the demand 3 has been described in this figure, when there is a torque difference between the zoom lens of the lens device 1 and the lens device 2, each zoom lens It is conceivable that a deviation occurs in the position of. Therefore, the alignment device 4 may be configured to convert the speed command value transmitted from the demand 3 into a position command value and transmit it to the lens device 1 and the lens device 2.

  Furthermore, although the zoom lens has been described as an example of the movable optical member in the drawing, the same applies to a focus lens or an iris.

  FIG. 3 is a diagram showing an example of a control command sequence for instructing a shot function by a shot switch operation of demand 3. As described in the background art, the shot function terminates a series of shot functions when a shot completion is transmitted from the lens device. When the shot function is operated in a plurality of lens devices, the timing at which the shot is completed may be different in each lens device, and it is necessary to continue the shot function until the shot is completed in all the lens devices. In this figure, an example in which the timing of completing a shot is different in each lens device will be described. Also in this drawing, a zoom lens is described as an example of the movable optical member.

  First, in S301, when the demand 3 detects that the shot switch has been pressed, the demand 3 transmits a preset shot position to the alignment device 4 (S311). In S <b> 312 and S <b> 313, when the alignment device 4 receives the shot position, the alignment device 4 transmits the shot position to each of the lens device 1 and the lens device 2. When receiving the shot position, the lens device 1 and the lens device 2 hold the shot position. In S314, the lens apparatus 1 transmits the current position of the zoom lens to the alignment apparatus 4 as a return command for the shot position received in S312. Similarly, in S315, the lens apparatus 2 transmits the current zoom lens position to the alignment apparatus 4. When the matching device 4 receives S314 and S315 which are return commands of the lens device 1 and the lens device 2, the matching device 4 selects a return command to be transmitted to the demand 3 according to the contents of the respective return commands. Since S314 and S315 are commands at the current position similar to the return command described with reference to FIG. 2, either one of the lens device 1 or the lens device 2 is selected and transmitted to the demand 3 as it is (S316). .

  Next, in S321, the demand 3 transmits a preset speed (for example, the highest speed) to the matching device 4. In S322 and S323, the alignment device 4 transmits the command command of the speed command received in S321 to the lens device 1 and the lens device 2. The lens device 1 and the lens device 2 each drive the zoom lens toward the shot position at a speed based on the received speed command. In S324, the lens apparatus 1 transmits the current zoom lens position to the matching apparatus 4 as a return command. Similarly, in S325, the lens apparatus 2 transmits the current zoom lens position to the alignment apparatus 4. As in S316, the alignment device 4 selects either one of the lens device 1 or the lens device 2 and sends it to the demand 3 as it is (S326). The transmission / reception of the control commands in S321 to S326 is repeated until the zoom lens reaches the shot position.

  FIG. 3 illustrates an example in which the zoom lens of the lens apparatus 1 reaches the shot position first, and then the zoom lens of the lens apparatus 2 reaches the shot position. S331 to S333 transmit the speed command transmitted from the demand 3 to the lens device 1 and the lens device 2, respectively, similarly to S321 to S323. At this time, it is assumed that the zoom lens of the lens apparatus 1 has reached the shot position. In S334, the lens apparatus 1 transmits a shot completion command to the alignment apparatus 4. In S335, since the lens apparatus 2 has not yet reached the shot position, the lens apparatus 2 transmits the current zoom lens position to the alignment apparatus 4.

  Since the sending back commands received from the lens device 1 and the lens device 2 are different from each other, the matching device 4 performs processing for selecting the sending back command. When a send completion return command is transmitted to the demand 3, the demand ends a series of shot operations. Therefore, in S336, the alignment device 4 selects the current zoom lens position return command received from the lens device 2. , Send to demand 3. When the demand 3 receives the send back command in S336, the demand 3 continues the shot function and transmits a command command for the speed command to the matching device 4 (S341). When the matching device 4 receives the speed command of S341, the lens device 1 has already completed the shot operation. Therefore, the matching device 4 converts the speed command value of S341 into a command command of the speed command value 0 and transmits it to the lens device 1. (S342). The command command of the speed command value of S341 is transmitted to the lens apparatus 2 as it is (S343). Since the lens apparatus 1 receives the command command with the speed command value 0, the movable optical member is not driven.

  In step S <b> 344, the lens apparatus 1 transmits the current zoom lens position to the alignment apparatus 4. The lens device 2 drives the zoom lens toward the shot position. At this time, it is assumed that the lens device 2 has also reached the shot position. In step S345, the lens apparatus 2 transmits a shot completion return command to the alignment apparatus 4. Since the sending back commands received from the lens device 1 and the lens device 2 are different from each other, the matching device 4 performs processing for selecting the sending back command. Since the shot completion return command has already been received from the lens device 1, the alignment device 4 selects the return return command from the lens device 2 and transmits the shot completion return command to the demand 3 (S346).

  Since demand 3 receives the completion of the shot, a series of shot operations are terminated. As described above, the alignment device 4 transmits a shot completion return command to the demand 3 for the first time by receiving a shot completion return command from each of the lens device 1 and the lens device 2. Therefore, even if the shot is completed early with one lens device, the demand 3 can continue the shot operation until the other is completed. It never ends.

  FIG. 4 is a diagram showing an example of a control command sequence for commanding ON / OFF of the image stabilization function by operating the image stabilization switch of demand 3. As explained in the background art, the lens device activates the image stabilization function by receiving an anti-vibration ON command, but naturally the image stabilization function is effective for lens devices that are not equipped with the image stabilization function. I can't. In such a case, an inconsistency occurs in that the anti-vibration function is effective in one lens device, and the anti-vibration function does not operate in the other lens device. In this figure, an example of controlling the lens device and a state in which the demand is matched in the case where the anti-vibration function is mounted on only one of the lens devices will be described.

  First, in S401, when the demand 3 detects that the image stabilization switch has been pressed, the demand 3 transmits an image stabilization ON command command to the matching device 4 (S411). In S <b> 412 and S <b> 413, when receiving the image stabilization ON, the matching device 4 transmits the image stabilization ON command command to each of the lens device 1 and the lens device 2. In FIG. 3, an example in which the lens device 1 is equipped with the image stabilization function and the lens device 2 is not equipped with the image stabilization function will be described. When the lens apparatus 1 receives the image stabilization ON in step S412, the lens apparatus 1 activates the image stabilization function and drives the image stabilization. In step S414, a vibration isolation ON return command is transmitted to the matching device 4.

  When the lens apparatus 2 receives the image stabilization ON in S413, since the image stabilization function is not installed in the lens apparatus 2, the image stabilization OFF is transmitted to the matching apparatus 4 as a return command (S415). Since the sending back commands received from the lens device 1 and the lens device 2 are different from each other, the matching device 4 performs processing for selecting the sending back command. When the anti-vibration ON send back command is transmitted to the demand 3, the lens device 2 turns on the LED indicating that the anti-vibration function is effective even though the anti-vibration function is not operating. End up.

  Therefore, in S <b> 416, the matching device 4 selects the image stabilization OFF send-back command received from the lens device 2 and transmits it to the demand 3. Further, the aligning device 4 transmits an anti-vibration OFF command command to the lens device 1 so that the lens device 1 is also matched (S421). When receiving the image stabilization OFF, the lens apparatus 1 disables the image stabilization function and stops the image stabilization. From the above, it is possible to prevent the inconsistent state that the image stabilization function is invalid in both lens devices, the image stabilization function is valid in one lens device, and the image stabilization function is invalid in the other lens device. Further, the LED indicating the state of the image stabilization function of demand 3 is also turned off, and it can be clearly indicated to the user that the image stabilization function is invalid in both lens devices.

  In FIG. 4, the ON / OFF of the image stabilization function has been described, but the present invention is not limited to this. For example, an inconsistent state can be prevented by the same processing as long as the function setting ON / OFF is instructed, such as a tracking function for limiting the movable region of the movable optical member.

  In the present embodiment, the connection between the lens device 1, the lens device 2, the demand 3 and the matching device 4 has been described as wired serial communication. However, the present invention is not limited to this and may be a wireless connection.

  Furthermore, in the present embodiment, the imaging system using two lens devices has been described. However, the present invention is not limited to this, and two or more lens devices may be used.

[Example 2]
An imaging system according to the second embodiment of the present invention will be described below with reference to FIGS.

  2. Description of the Related Art Conventionally, with regard to an imaging device that includes a detachable lens device and a camera, serial communication is provided for connection between the lens device and the camera, and the lens device is controlled from the camera by the serial communication. A state in which connection is established by the serial communication is referred to as a serial mode, and a state in which communication is not established is referred to as a parallel mode. In the present embodiment, an example in which two lens devices are controlled from a camera by serial communication will be described.

  FIG. 5 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 alignment device 4 of the photographing system is connected to the lens device 1, the lens device 2, the camera 5, and the camera 6.

  The matching device 4 has a CUP 41. The CPU 41 receives a command command transmitted from the camera 5 and the camera 6 and transmits the command command to the lens device 1 and the lens device 2, respectively. Furthermore, the sending back command transmitted from the lens device 1 and the lens device 2 is received, respectively, and when the contents of the sending back command are different, the sending command to be sent to the camera 5 or the camera 6 is selected. Further, the control command is transmitted so as to correct the mismatch between the lens apparatuses or between the lens apparatus and the camera.

  FIG. 6 is a diagram illustrating a sequence in which the lens apparatus and the camera establish serial communication when the camera is powered on.

  First, in S601, the power supply of the camera 5 is turned on. When the power is turned on, the camera 5 transmits a connection command command to the matching device 4 in S611. When the matching device 4 receives the connection command command, the matching device 4 transmits the connection command command to each of the lens device 1 and the lens device 2 (S612, S613). When the lens device 1 and the lens device 2 each receive a connection command command, the lens device 1 and the lens device 2 shift to a serial mode that permits a command by serial communication from the camera, and send a response return command to the matching device 4 (S614, S615). .

  When the matching device 4 receives a response return command from each of the lens device 1 and the lens device 2, the matching device 4 transmits a response return command to the camera 5 to which the connection command command has been transmitted (S616). When the camera 5 receives a response return command, the camera 5 shifts to a serial mode in which a command is given through serial communication. Next, in S602, the power source of the camera 6 is turned on. When the power is turned on, the camera 6 transmits a connection command command to the matching device 4 in S621. Since the lens device 1 and the lens device 2 are already in the serial mode, the matching device 4 transmits a response return command to the camera 6 (S622). When the camera 6 receives a response return command, the camera 6 shifts to a serial mode in which a command is given through serial communication. From the above, since the lens device 1, the lens device 2, the camera 5, and the camera 6 are all in the serial mode, the lens device can be controlled by serial communication from the camera.

  FIG. 7 is a diagram illustrating a sequence in a case where the lens apparatus 2 is a lens apparatus that does not support the serial mode.

  S701 to S714 are the same as S601 to S614 in FIG. Since the lens apparatus 2 does not support the serial mode, even if a connection command command is received in S713, a response return command is not transmitted. The matching device 4 receives a response return command from the lens device 1, but does not receive a response return command from the lens device 2, and therefore does not transmit a response return command to the camera 5. Therefore, although the camera 5 has transmitted the connection command command, the response return command is not transmitted, and therefore the camera 5 is in the parallel mode.

  Further, the lens apparatus 1 shifts to the serial mode when the connection command command is received in S712. However, since the serial communication command command is not transmitted thereafter, the lens apparatus 1 shifts from the serial mode to the parallel mode. . Next, in S702, the camera 6 is powered on. When the power is turned on, in S721, the camera 6 transmits a connection command command to the matching device 4. The alignment device 4 does not transmit a send back command to the camera 6 because the lens device 1 and the lens device 2 are in the parallel mode.

  Therefore, similarly to the camera 5, the camera 6 is in a parallel mode because a response return command is not transmitted. From the above, since the lens device 1, the lens device 2, the camera 5, and the camera 6 are all in the parallel mode, the lens device cannot be controlled by serial communication from the camera. As described above, when only one lens device is compatible with the serial mode and the serial communication is controlled from the camera, the movable optical member is driven only by one lens device and the other is not driven. Matching can be prevented.

  As described with reference to FIG. 6, when both the lens device 1 and the lens device 2 are lens devices compatible with the serial mode, the lens device can be controlled by serial communication from the camera. In the first embodiment, the command source of the control command is only the demand 3, whereas in the second embodiment, there are two command sources of the camera 5 and the camera 6.

  However, in this case, the sequence of control commands for each function is the same as the sequence described in FIGS. 2 to 4 of the first embodiment, and only the part corresponding to the demand 3 is the camera 5 or the camera 6 and is matched. An excellent state can be realized. In other words, the return command for the command command transmitted from the camera 5 may be transmitted only to the camera 5, and the return command for the command command transmitted from the camera 6 may be transmitted only to the camera 6.

  Further, when command commands are transmitted from both the camera 5 and the camera 6 at the same time, one of the cameras set in advance may be prioritized and the command command of the other camera may be ignored. Furthermore, when the command command transmitted at the same time is a speed command or a position command of the movable optical member, an addition value or an average value of both command values is used as a command value to be transmitted to the lens device. It is good also as control.

  In this embodiment, an example in which a connection command command for establishing serial communication is transmitted when the camera power is turned on has been described. However, the present invention is not limited to this. For example, the connection may be executed by using a serial mode / parallel mode switch or the like as a trigger.

  In this embodiment, the configuration in which both the camera 5 and the camera 6 are connected to the matching device has been described. However, only one of the configurations may be connected.

  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.
