Change the monomer of camera lens 100 title, for example " manufacturer's name M.40-150mm F2.8 " show in this wise manufacturer's name, focal length,
F-number etc..In the case where converter camera lens 300 is installed on the replacing camera lens 100, such as " M.40-150mm F2.8+
M.EC-14 " adds replacing camera lens 100 in this wise and is installed on the title of the converter camera lens 300 of the replacing camera lens 100, and to
Camera body 200 sends the title.
As described above, camera body 200 change camera lens 100 identification when used " member id ", " camera lens ID ",
" H/W_Ver ", " shot sequence number ", " F/W_Ver ", in addition, also using above-mentioned " camera lens title " and " substrate sequence "
As camera lens identification information.Wherein, shot sequence number and camera lens title are changed in mounting converter camera lens 300.
Next, the adjustment data to converter camera lens 300 illustrate.The converter camera lens 300 of present embodiment is not
With the control units such as CPU and memory etc..Therefore, converter camera lens can not have the intrinsic adjusted value of converter camera lens in itself.
In addition, " the adjustment data of converter camera lens " refer to " change each individual adjustment data+converter camera lens during lens monomer
Design load ".Here, the design load of converter camera lens refers to " design load obtained in design or optical simulation " or " passes through examination
The value (average value etc.) that system etc. obtains ".
Because converter camera lens there can not be adjusted value in itself, carried out such as so changing camera lens 100 in the present embodiment
Lower processing：To the design load of the adjustment data addition converter camera lens of each replacing camera lens individual, to generate converter camera lens
Adjust data.In addition, " addition " is not meant to imply that the add operation on counting, but mean to implement some computings, such as
Mean to be multiplied by " design load of converter camera lens " or be added the calculation process of 2 times of " design load of converter camera lens " etc..
When generating the adjustment data of converter camera lens 300, to the converter mirror do not sold when camera lens 100 is changed in sale
For head, the firmware of camera lens 100 is changed by being updated when the converter camera lens is sold, the converter can be suitably used
Camera lens.In this case, in order to change ensuring and optimizing for the data area in camera lens 100, mainly with 3 following numbers
Classified according to form.
DaTa form 1：It is identical with changing lens monomer
DaTa form 2：It is exclusive data, and calculated with changing lens monomer data × coefficient
Data mode 3：It is exclusive data, stores special initial data
Above-mentioned DaTa form 1 is the data identical with changing lens monomer, will not cause to count because of converter camera lens
According to increase.DaTa form 2 is the data of coefficient type, is then by primary mirror for example, if 1.4 times of converter camera lens
The data of head (the replacing camera lens of installation) are multiplied by 1.4, (1.4)2The type that such coefficient can calculate.Data mode 3 is not
It is simple coefficient, but by the formula or the optical design that can not be formulated of complexity come the data that determine, more
During new firmware, data storage is in itself.
Moreover, according to the frequency using data, classification is 3 following data types.
Data type 1：The data type being used in control process
Data type 2：Batch sending data type
Data type 3：State sends data type
Above-mentioned data type 1 is the data being used in control process, such as is driven changing the actuator in camera lens 100
The data constantly used in dynamic, calculation process etc..It is in the case where needing restoring data, deploys in ram region etc., in advance
The data of first operational data and the type deployed in storage region.
Data type 2 is Batch sending data type, and camera lens 100 and camera body 200 are being changed when being to turn on power supply
Between the lens data that carries out send in the data that use.As long as when switching on power can use, fortune can also be passed through
Try to achieve.
Data type 3 is that state sends data type, is to change the moment between camera lens 100 and camera body 200 same
The data used in the case of step in state transmission.If easily carrying out computing, computing is carried out as needed, is answered in computing
In the case of miscellaneous, deploy in the storage region for changing the CPU41 in camera lens 100.
In the present embodiment, when generating the adjustment data of converter camera lens 300, data type is divided into 3 types,
Thus, it is possible to the optimization for the calculation process for seeking firmware.
Next, the size of data of image planes speed (Defmm/s) is illustrated.From camera lens 100 is changed to camera
The data that main body 200 is sent include the data of image planes speed, the movement of the image planes when image planes speed is focus lens movement
Speed.For example, image planes speed Def is the maximum of image planes speed, 1Byte size of data is distributed image planes speed Def.Logical
1Byte size of data is enough in normal replacing camera lens, but due to installing the converter camera lens 300 of increment mirror-type, institute
Become faster with image planes speed, so that 1Byte size of data is inadequate sometimes.Then, turning for increment mirror-type is being installed
In the case of parallel operation camera lens 300, as long as image planes speed Def (mm/s) size of data is changed into 2Byte.
Next, the flow chart shown in using Fig. 6 and Fig. 7, the converter mirror performed to the CPU41 for changing camera lens 100
First 300 detection and its processing illustrates.According to the program stored in storage part 37, CPU41 is each in camera lens 100 to changing
Part is controlled, and thus performs the flow.In addition, converter camera lens 300 is abbreviated as teleconverter in figure.
In the flow of converter Shot Detection shown in Fig. 6, first if switch on power supply (S1), then reset releasing is carried out
(S3), and carry out camera lens CPU initialization process (S5).Here, in the time point to switch on power, temporarily make the mirror of replacing camera lens 100
Head CPU41 etc. changes circuit in camera lens 100 etc. and resetted.
If having carried out camera lens CPU initialization process, followed by the inspection (S7) of converter Shot Detection terminal.
Here, CPU41 utilizes I/O45, I/O46, detection terminal A55a and terminal B55b state.The detection as a result, CPU41 energy
Enough detect whether that converter camera lens 300 is installed, in the case where being provided with converter camera lens 300, CPU41, which can be identified, to be turned
The species of parallel operation camera lens 300.
If being converted the inspection of device Shot Detection terminal, next determine whether it has received ResetLens and refer to
Make (S9).If switch on power supply, then from camera body 200 to the instruction for changing the transmission reset request of camera lens 100.In the step
In, ResetLens instructions are determined whether it has received, in the case where not receiving, wait ResetLens to be received to instruct.
It is if judgement as a result, receiving ResetLens instructions, the step after step S11 in step S9
In, handled according to the presence or absence of converter camera lens 300 and species.First, determine whether converter camera lens 300 is installed
(S11).Here, the result of the converter Shot Detection terminal inspection in step S7 is judged (reference picture 4).
It is judgement as a result, in the case of non-mounting converter camera lens 300 in step S11, (S11 → no), change
For the camera lens title of camera lens (replacing camera lens) monomer, shot sequence number (S21).In this case, in non-mounting converter mirror
First 300 and be provided with change the monomer of camera lens 100 state.In this case, camera lens title and shot sequence use and replacing
The related camera lens title of the monomer of camera lens 100 and shot sequence number.
Then, camera lens identification data (S23) is responded to camera body.It is used for if received from camera body 200
Request sends the AskDataS instructions of the identification data of camera lens, then sends camera lens identification data to camera body 200.
Then, the shot information batch data for carrying out camera lens (replacing camera lens) monomer sends (S25).If from photograph owner
Body 200 is received for asking the AskDataM for sending lens data to instruct, then Batch sending is changed in camera lens 100 as former state
The shot information stored in storage part 37.
Return to step S11, it is judgement as a result, in the case where being provided with converter camera lens 300 in the step, connect down
