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

  The optical apparatus according to the first embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a functional block diagram of the lens apparatus in the present embodiment. In FIG. 1, reference numerals 100 and 200 denote lens devices. In the present embodiment, it is assumed that the setting data is copied from the lens apparatus 100 to the lens apparatus 200 (hereinafter, inter-lens copying). Hereinafter, a copy source lens at the time of copying between lenses is described as a copy source, and the same copy destination lens is described as a copy destination.
The lens device 100 mainly includes a focus lens 101, a zoom lens 102, an iris 103, a calculation unit (control unit) 110, a storage unit (storage unit) 111, a communication unit (communication unit) 112, and a transmission determination unit 113. .

  The focus lens 101 is a lens that changes the object distance, the zoom lens 102 is a lens that changes the focal distance, and the iris 103 is a diaphragm unit that adjusts the amount of light.

  The focus lens 101 is connected to a focus drive unit 104 that drives the focus lens 101 and a focus position detection unit 105 that detects the position of the focus lens 101. A zoom driving unit 106 that drives the zoom lens 102 and a zoom position detection unit 107 that detects the position of the zoom lens 102 are connected to the zoom lens 102. The iris 103 is connected to an iris driving unit 108 that drives the iris 103 and an iris position detection unit 109 that detects the position of the iris 103.

  In this embodiment, encoders are used for the position detection units 105, 107, and 109, but the present invention is not limited to this, and a potentiometer may be used. The focus position detection unit 105 outputs a position signal to the calculation unit 110 as the focus lens 101 is driven. Similarly, the zoom position detector 107 outputs a position signal to the calculator 110 as the zoom lens 102 is driven, and the iris position detector 109 is driven as the iris 103 is driven.

  The calculation unit 110 outputs a drive signal to the focus drive unit 104 in order to drive the focus lens 101. Similarly, a drive signal is output to the zoom drive unit 106 for driving the zoom lens 102 and to the iris drive unit 108 for driving the iris 103. Further, the communication data is output to the communication unit 112 and the communication data from the communication unit 112 is input. Further, a request for lens specification information is output to the communication unit 112, and an inter-lens copy execution request is output to the transmission determination unit 113.

The storage unit 111 is a memory, and details of data to be stored will be described with reference to FIG.
The communication unit 112 communicates with the lens device 200.
The transmission determination unit (control unit) 113 determines whether or not the data in the storage unit 111 may be transmitted from the communication unit 112 to the lens apparatus 200 when an inter-lens copy execution request is input from the calculation unit 110. . For the determination, lens specification information described later with reference to FIG. 2 is used.
Also, a switch (not shown) is provided, and it is assumed that copying between lenses can be performed by switch input.
The lens device 200 has the same configuration as the lens device 100.

  FIG. 2 is an example of lens specification information (specification information), which is a table of specification information for four types. As shown in the figure, the lens specification information includes zoom ratio, presence / absence of image blur correction function, presence / absence of extender and magnification, information on presence / absence of field angle correction function, focus lens drive specification (servo / manual type), zoom Information unique to the device (lens specific information) relating to hardware specifications such as lens type information such as whether or not an electromagnetic clutch is connected between the lens and the zoom driving means is included. In addition, the information includes software information such as the type and version of the control software and the configuration specifications in the ROM, and a plurality of pieces of information such as the current settings and adjustment states (lens setting information). In this embodiment, the specification information of the lens device 100 is the specification information of the lens indicated by “A” shown in FIG. 2, and the specification information of the lens device 200 is the specification information of the lens indicated by “B”.

FIG. 3 is a flowchart showing processing at the time of copying between lenses of the lens apparatus 100 as a copy source in the present embodiment.
When an inter-lens copy execution request is input from the calculation unit 110, the process proceeds to S301.

In S301, the communication unit 112 requests the lens specification information shown in FIG. 2 from the lens apparatus 200, and the process proceeds to S302.
In S302, it is determined whether lens specification information has been received from the lens apparatus 200. If received, the process proceeds to S303, and if not, the process returns to S302.
In S303, any number of setting data for performing inter-lens copying is read from the storage unit 111, and the process proceeds to S304. In this embodiment, setting data is read one by one.

  In S304, for each setting data read in S303, the transmission determination unit 113 determines whether or not the inter-lens copy can be executed based on the comparison result between the lens specification information acquired in S302 and the lens specification information of the lens apparatus 100. The process proceeds to S305. In this embodiment, the copy source has an image blur correction function, whereas the copy destination has no image blur correction function. Therefore, in the determination process according to the present exemplary embodiment, it is determined that the copy execution is not performed for the setting related to the image blur correction. By performing the determination in S304, it is possible to prevent a malfunction in the copy destination, such as signal output related to a non-mounted function and influence on other functions.

In S305, based on the determination result in S304, if inter-lens copying can be performed, the process proceeds to S306, and if not, the process proceeds to S307.
In S306, the setting data is transmitted from the communication unit 112 to the lens apparatus 200, and the process proceeds to S307.
In S307, it is determined whether or not the process related to the inter-lens copy has been completed for all the setting items. If completed, the process is completed. If not, the process proceeds to S303.
While the lens apparatus 100 performs the processing of FIG. 3, the lens apparatus 200 stores the setting data received from the lens apparatus 100 in the storage unit 211.

  FIG. 4 is a table showing setting data to be copied between lenses in the present embodiment and setting data of each data item before and after execution of copying between lenses. The italic characters in the table indicate that the setting data of the lens apparatus 200 after the inter-lens copy is not copied. For example, the setting data related to the image blur correction function (ON / OFF of the RET switch function and the image blur correction function) of the lens apparatus 100 having the image blur correction (IS) function does not have the image blur correction function. It is not copied to the lens device 200. On the other hand, the setting data related to the view angle correction function of the lens apparatus 100 that does not have the view angle correction function is not copied to the lens apparatus 200 that has the view angle correction function. That is, by not copying setting data relating to a function from a lens having no function to a lens having the function, it is possible to prevent the function of the copy destination lens from being restricted. Also, setting data for limiting the driving range such as the zoom tracking function is not copied. The zoom tracking function is to limit the driving range of the zoom lens, and a normal zoom lens device is a function. Copying from a lens device for which the zoom tracking function is enabled to a lens device for which it is disabled will limit the zoom movable range of the copy destination lens device. In order not to reduce it, it is controlled not to copy. Data items (for example, function assignment to AUX SW, ON / OFF of angle of view correction function) regarding functions (for example, angle of view correction function) that are not shared between lens apparatus 100 and lens apparatus 200 Is not set to change the setting data. For the data item (for example, changing from zoom tracking OFF to ON) that reduces the drive range of the predetermined function by changing the setting data, the setting data is not changed. Further, data items that do not affect the user's operation even when the setting data is changed (for example, selection of position control / speed control related to the zoom control method) are copied. On the other hand, the common functions are surely copied.

  As described above, based on the comparison result of the lens specification information, it is possible to perform inter-lens copying without automatically affecting the functions specific to the model by automatically determining whether or not copying can be performed for each function.

  In the present embodiment, the lens specification information of FIG. 2 is used in the comparison of the lens specification information. However, the present invention is not limited to this. Lens specification information to be selected may be selected. Further, the setting data is read one by one. However, the present invention is not limited to this, and a plurality of related setting data may be read collectively. Further, in the inter-lens copy, the data items shown in FIG. 4 are set as the target of the setting data. However, the present invention is not limited to this, and various setting data may be the target. In addition, the execution of copying between lenses can be started by a switch provided in the lens apparatus. However, the present invention is not limited to this, and it may be executable from an external device such as a display unit or a PC that can set and check functions. It is also possible to execute automatically by connection of. In addition, a display device may be provided to display a list of inter-lens copy results and a warning display indicating that copying is not possible. Also, in the configuration of the lens device, the copy source and the copy destination for performing the inter-lens copy are the same, but the configuration of the copy destination is not the same as long as it has an inter-lens copy function and can communicate between lenses. May be. The communication method between the lenses may be wired communication or wireless communication, as long as the communication unit can communicate.

  According to the present embodiment, it is possible to provide an optical apparatus that can automatically determine whether copying can be executed for each function based on a comparison result of lens specification information.

  An optical apparatus according to a second embodiment of the present invention will be described below with reference to FIGS.

FIG. 5 is a functional block diagram of the lens apparatus of the present embodiment. The lens apparatus 100 according to the first embodiment is different from the lens apparatus 100 in that a photographing application selection unit 114 is added to the lens apparatus 100. On the other hand, the lens device 200 has the same configuration as the lens device 100 and the point that the lens device 100 performs inter-lens copying from the lens device 100 to the lens device 200 is the same as in the first embodiment. In this embodiment, the specification information of the lens device 100 is the specification information indicated by “C” shown in FIG. 2, and the specification information of the lens device 200 is the specification information indicated by “C”.

  In FIG. 5, a photographing application selection unit 114 is a display unit provided in the lens apparatus 100, and can select a photographing application of the lens apparatus 200 that is an inter-lens copy destination on the display unit.

  FIG. 6 is a list of photographing applications that can be selected by the photographing application selection unit 114. For example, field shooting such as on a stadium or horse racing, TV studio shooting, or tripod shooting can be selected. In this embodiment, it is assumed that pan head photography is selected.

  FIG. 7 is a flowchart showing processing at the time of copying between lenses of the lens apparatus 100 as a copy source in the present embodiment.

Only the difference from FIG. 3 described in the first embodiment will be described below.
In S701, the shooting application selected by the shooting application selection unit 114 is read, and the process proceeds to S303.
In S <b> 702, the setting data read in S <b> 303 in the transmission determination unit 113 is based on the lens specification information acquired in S <b> 302, the comparison result of the lens specification information of the lens apparatus 100, and the photographing application read in S <b> 701. Thus, it is determined whether or not the inter-lens copy can be executed, and the process proceeds to S305. In this embodiment, the lens specification information of the copy source and the copy destination is the same, but the pan / tilt shooting is selected as the copy destination shooting application. Therefore, in the specific example of the determination process, it is determined that the copy execution is rejected for the setting related to the pan head. In other words, the lens apparatus 200 at the copy destination may maintain the maximum degree of freedom regarding the function related to the pan / tilt head shooting, or may be intentionally used with the setting intended for the pan / tilt head function. Since it is assumed, control is performed so as not to copy setting data regarding the camera platform from the other lens apparatus 100. By performing the determination in S702, it is possible to prevent a malfunction of the copy destination, such as a signal output related to a non-mounted function or an influence on other functions.
While the lens apparatus 100 performs the processing of FIG. 7, the lens apparatus 200 stores the setting data received from the lens apparatus 100 in the storage unit 211.

  FIG. 8 is a table showing setting data to be copied between lenses in this embodiment and setting data of each data item before and after execution of copying between lenses. The italic characters in the table indicate that the setting data of the lens apparatus 200 after the inter-lens copy is the setting data that is not copied, as in the first embodiment. For example, setting data relating to the pan head setting of the lens device 100 (ON / OFF of the pan head) is not copied to the lens device 200 for which pan head photographing is selected. Further, the image blur correction mode of the lens apparatus 100 in the shoulder holding mode is not copied to the lens apparatus 200 for which the pan / tilt shooting is selected. Also, setting data for limiting the driving range such as the zoom tracking function is not copied. On the other hand, common functions are copied.

  As described above, in addition to the comparison result of the lens specification information, by automatically determining whether copying can be performed for each function based on the shooting application, even if the lens specification information is the same, the desired setting data is obtained depending on the shooting application. It became possible to copy between lenses. In this embodiment, the copy destination shooting application is selected. However, the present invention is not limited to this, and the copy source shooting application may be selectable, or each lens apparatus selects the shooting application of its own device in advance. Anyway. In addition, although the lens device is provided with a selection unit for photographing use, it may be selectable from an external device such as a PC, or may be selected and confirmed anew when copying between lenses.

  According to the present embodiment, it is possible to provide an optical apparatus that can automatically determine whether or not copying can be performed for each function based on a comparison result of lens specification information and a selected photographing application.

An optical apparatus according to a third embodiment of the present invention will be described below with reference to FIGS.
The same functional configurations as those of the first and second embodiments are denoted by the same reference numerals and description thereof is omitted.

  The functional block diagram of the lens apparatus of the present embodiment has the same configuration as that of Embodiment 1 shown in FIG. Further, the point that the lens device 100 performs the inter-lens copy to the lens device 200 is the same as in the first and second embodiments. In the present embodiment, the specification information of the lens device 100 is the lens type D shown in FIG.

  FIG. 9 is a flowchart illustrating processing at the time of copying between lenses of the lens apparatus 100 that is a copy source according to the present exemplary embodiment.

Only differences from the flowchart of FIG. 3 described in the first embodiment will be described below.
In S901, the setting data read in S303 is converted into a value suitable for the copy destination lens based on the lens specification information acquired in S302 by the calculation unit 110, and the process proceeds to S306. In this embodiment, the copy source is a 10x lens device, and the copy destination is a 17x lens device. Therefore, specifically, at the shot position stored in memory (the position of the lens stored in advance), conversion is performed so that the shooting angle of view is the same or similar between the copy source and the copy destination. Further, the shot position stored in memory and the tracking position of zoom are converted so that they do not fall F. By performing the conversion in S901, the shooting angle of view can be reproduced by the shot function, and operations unintended by the user such as F drop due to ON / OFF of the function can be prevented.
While the lens apparatus 100 performs the processing of FIG. 9, the lens apparatus 200 stores the setting data received from the lens apparatus 100 in the storage unit 211.

  FIG. 10 is a table showing setting data to be copied between lenses in this embodiment and setting data of each data item before and after execution of copying between lenses. The italic characters in the table indicate setting data that has not been copied among the setting data of the lens apparatus 200 after copying between lenses, as in the first and second embodiments. In addition, italic bold letters in the table indicate setting data in which values converted by the lens apparatus 100 during inter-lens copying are set. For example, the memory position of the shot is converted to an angle of view that has the same angle of view in the lens device 200 based on the angle of view when the lens device 100 stores the memory. The zoom tracking position is converted to a position where the lens apparatus 200 does not drop F. On the other hand, data items related to common functions are reliably copied.

  From the above, by converting the setting data to a value suitable for the copy destination based on the comparison result of the lens specification information, it is possible to copy between lenses considering the shooting angle of view and F drop position even between different models. . In the present embodiment, data conversion is performed based on the comparison result of the lens specification information. However, the photographing application selection unit described in the second embodiment may be provided, and data may be converted in consideration of the photographing application.
