Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an optical apparatus such as a camera and binoculars capable of correcting camera shake of a subject, an inspection system and an inspection method for a correction lens driving system thereof.

[0002]

2. Description of the Related Art Generally, in a drive system using a motor and a gear, there are individual differences in drive characteristics due to meshing of gears and the like. In particular, position control and drive control of the shake correction lens are greatly affected by individual differences in the drive system. Therefore, it is necessary to adjust the correction lens drive system in order to exhibit a certain or more shake correction performance in an optical device with a shake correction function.

For example, in the conventional method of adjusting a correction lens drive system of an optical device with a shake correction function described in Japanese Patent Application Laid-Open No. 7-261228, the optical device is fixed to a shaking table,
The shaking table is driven while the optical device and the external inspection device are connected. Then, various adjustments are made while monitoring the drive characteristics of the correction lens drive system with an external inspection device in a state where the SIN waveform is applied to the optical device.

[0004]

In practice, however, there are waveforms, such as discontinuous waveforms, which are extremely difficult or impossible to realize with a shaking table. Even if such a vibration waveform could be realized as a drive signal, it would be reproduced in a form that was transformed into a smooth waveform by the intervening shaking table, and the optical equipment would be given a blunt waveform. Become. When the optical device is not firmly fixed to the shaking table, driving the shaking table may cause the optical device to vibrate with a waveform different from the vibration waveform of the shaking table. In either case, the drive characteristics of the correction lens drive system may not be inspected correctly and may not be adjusted correctly. Therefore, in the inspection and adjustment method actually performed by applying vibration to the optical device, there is a limit to the inspection and adjustment of a part requiring high accuracy such as a correction lens driving system.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and it is possible to easily and accurately inspect and adjust a correction lens drive system without actually applying vibration to optical equipment. It is an object of the present invention to provide a possible optical device with a shake correction function, a shake correction function inspection system and an inspection method.

[0006]

In order to achieve the above object, a shake correction function inspection system according to the present invention comprises: a shake correction means for correcting a shake; a driving means for driving the shake correction means; Control means for controlling the correction means, position detection means for detecting the position of the shake correction means,
Inspection means for inspecting the driving characteristics of the driving means; a pseudo-oscillation signal between the inspection means and the control means; a communication means for communicating a detected position signal between the inspection means and the position detection means; Storage means for temporarily storing the shake signal and the detected position signal.

That is, instead of giving vibration to the optical device itself, a pseudo shake signal (equivalent to the case where vibration is actually given to the optical device) is sent from the inspection means outside the optical device to the control means via the communication means. Target position data) is transmitted, and the driving unit is controlled based on the pseudo shake signal, and the correction unit (correction lens) is actually driven. Furthermore, the position of the correction lens actually driven is detected by the position detection means, and a detection position signal (detection position data) corresponding to the position of the correction lens is transmitted to the external inspection means via the communication means. By comparing the pseudo shake signal transmitted by the external inspection means with the received detection position signal, it is possible to know the drive characteristics of the drive means. As a result, the inspection and adjustment of the correction lens drive system can be performed without actually applying vibration to the optical device, and the inspection and adjustment can be made extremely simple and easy. Further, since no vibration is given to the optical device, there is no error caused by improper fixing of the optical device to the vibration table.

In general, the signal communication speed between the external inspection means and the control means and between the external inspection means and the position detection means by the communication means depends on the signal communication speed between the control means and the driving means. Although the speed is lower than the speed, once the signals to be communicated are stored in the storage means (RAM or the like), it is possible to adjust the difference between these signal communication speeds.

In the above configuration, the inspection means may be configured to generate a signal corresponding to an arbitrary vibration waveform.
That is, since the inspection and adjustment of the correction lens drive system are performed without actually applying vibration to the optical device, the inspection and the vibration waveform cannot be realized by the method of actually applying vibration to the optical device using the conventional vibration table. Adjustment is also possible.

The storage means transmits the pseudo shake signal transmitted from the inspection means to the drive means sequentially from each address at a predetermined timing, and transmits the detected position signal from the position detection means sequentially to the pseudo shake signal. You may comprise so that it may memorize | store sequentially in the corresponding address. Since the pseudo shake signal is stored by the external inspection means or can be generated at any time, it is no longer necessary to store it by the storage means after transmitting to the correction lens driving means. Further, since the detection position signal is generated by transmitting the pseudo shake signal, the total number of the pseudo shake signals and the total number of the detection position signals are the same. Therefore, this configuration makes it possible to reduce the required storage capacity of the storage means. Further, if there is room in the capacity of the storage means, more position signals may be detected than the total number of pseudo shake signals.

[0011] Also, an optical apparatus with a shake correction function according to the present invention includes a shake correction lens inserted into a part of an imaging optical system;
Driving means for driving the shake correction lens, position detection means for detecting the position of the shake correction lens, communication means for communicating a predetermined signal between inspection means provided outside the optical device, and communication means The driving unit is driven using the pseudo shake signal input from the inspection unit, and the detection unit outputs a detection position signal corresponding to the position of the shake correction lens that is driven by the driving unit and detected by the position detection unit. Control means.

[0012] In the above configuration, a storage means for temporarily storing the pseudo shake signal and the detected position signal may be further provided.

Further, the pseudo shake signal may be a signal corresponding to an arbitrary vibration waveform.

Further, the storage means transmits the pseudo shake signal transmitted from the inspection means to the driving means sequentially from each address at a predetermined timing, and transmits the detected position signal from the position detection means sequentially to the pseudo shake signal. You may comprise so that it may memorize | store sequentially in the corresponding address.

As described above, by connecting the optical apparatus with the shake correction function of the present invention to the shake correction function inspection apparatus of the present invention via the communication means, the shake correction can be performed without actually applying vibration to the optical apparatus. The operating characteristics of the mechanism can be adjusted.

Further, the method for inspecting a shake correction function according to the present invention comprises:
A device having a shake correcting unit for correcting shake, a driving unit for driving the shake correcting unit, a control unit for controlling the shake correcting unit, and a position detecting unit for detecting a position of the shake correcting unit. The shake signal is input, the shake correction means is driven by the drive means using the pseudo shake signal, the position is detected by the shake correction means by the position detection means, and the drive characteristics of the drive means are inspected using the detected position signal. .

In the above method, the pseudo shake signal may be a signal corresponding to an arbitrary vibration waveform.

As described above, according to the method for inspecting the shake correction function of the present invention, it is possible to inspect the shake correction function, particularly the drive characteristics of the shake correction lens and the like without actually vibrating the device having the shake correction function. It is possible to make inspection and adjustment extremely simple and easy. Further, since no vibration is given to the device such as the optical device, there is no error caused by improper fixing of the device to the vibration table.

The image data dump section 511a dumps the image data from the signal processing section 44 to a memory 56 (RAM). The memory 56 stores the dumped image data. The image comparison / calculation unit 511b extracts an image corresponding to the reference image from the latest image data stored in the memory 56 as a reference image, and calculates a reference image position change amount with respect to the initially set reference image position. The shake amount in pixel units is obtained. Further, the image comparison calculation unit 511b sends the obtained shake amount to the coefficient conversion unit 52, obtains the shake inclination between the obtained shake amount and the previous shake amount, and calculates the shake amount at predetermined time intervals. The calculated value is sent to the coefficient conversion unit 52. The shake amount is obtained for each of the horizontal and vertical directions, is temporarily stored in the memory 56, and is sent to the shake display unit 12. The data selection unit 512 selects and extracts a plurality (for example, four) of shake amounts including the latest shake amount from the memory 56 using, for example, a predetermined reference time interval.
The predicted shake amount calculation unit 513 calculates the predicted shake amount using the selectively extracted shake amount in each of the horizontal and vertical directions.

Returning to FIG. 1, the coefficient conversion unit 52 uses the conversion coefficients stored in the memory 56 for the horizontal and vertical directions to output the output from the shake amount detection unit 51 to the correction lens unit 3. It is converted to the target angle position (drive amount).
Further, the coefficient conversion unit 52 calculates a correction coefficient according to the environmental temperature detected by the temperature sensor 55, and corrects the horizontal and vertical target angle positions using the correction coefficient. However, no temperature correction is necessary for the output of the deceleration processing unit 52.

The lens 31 and the vertical shake correction lens 32 are driven.

FIG. 4 shows a block configuration of a drive control circuit 61 constituting a part of the servo circuit. First, the setting data SDGH and SDGV set in the drive control circuit 61 will be described. When the environmental temperature of the camera 1 changes, various characteristics of the drive system for shake correction change.
For example, the torque constant of each motor (see the motor 632 in FIG. 2) in the drive unit 6, the backlash of the drive system (movable mechanism) in the correction lens unit 3 and the drive unit 6 and the gear of the drive system in accordance with the environmental temperature change. (Gear part 322 in FIG. 2)
And the gear 631).

FIG. 5 shows a temperature characteristic of the motor torque which is one factor of this change. As is clear from the figure, when the ambient temperature deviates from the reference temperature (for example, 25 ° C.), the motor torque shows a value different from the value at the reference temperature. As a result, drive characteristics related to shake correction change. Thus, the basic gain in the horizontal and vertical directions (the drive gain at the reference temperature)
The driving characteristics vary when the environmental temperature obtained by the temperature sensor 55 deviates from the reference temperature.

Therefore, the correction gain setting section 54 generates a gain correction amount for correcting a change in drive characteristics due to each of the basic gains in the horizontal and vertical directions according to the environmental temperature obtained by the temperature sensor 55. In the present embodiment, a function (environment temperature is used as an argument) for obtaining a gain correction amount for individually correcting each variation such as motor torque, backlash, and gear hardness that occurs when the environment temperature deviates from the reference temperature. )But,
It is determined in advance for each of the horizontal and vertical directions. Then, for each of the horizontal and vertical directions, the environmental temperature detected by the temperature sensor 55 is input to each correction function, and the total value of the obtained values is obtained as a gain correction amount. These gain correction amounts in the horizontal and vertical directions are respectively set in the setting data SD.
The signals are output to the drive control circuit 61 as GH and SDGV.

A difference voltage between V and the output voltage VV from the vertical position detection unit 72 is obtained. The output voltages VH and VV are configured to be negative in a horizontal position detection unit 71 and a vertical position detection unit 72, which will be described later, so that in the addition circuits 606 and 607, the horizontal position detection unit 71 and the vertical position detection unit 72 Output voltage VH,
The difference voltage is obtained by adding VV.

The V / V 609 amplifies the input voltage into a voltage as a vertical proportional gain at a preset ratio with respect to the reference temperature. Here, the lateral proportional gain is the target position of the lateral vibration correcting lens 31 and the lateral vibration correcting lens 31 detected by the lateral position detecting unit 71.
The gain is proportional to the difference from the position. The vertical proportional gain is a gain proportional to the difference between the target position of the vertical shake correction lens 32 and the position of the vertical shake correction lens 32 detected by the vertical position detection unit 72.

The differentiating circuit 610 performs a differentiation by a preset time constant with respect to the reference temperature to the difference voltage obtained by the adding circuit 606 to obtain a voltage as a differential gain in the horizontal direction. The voltage obtained by the differentiating circuit 610 is the difference in speed in the horizontal direction (the difference between the target drive speed and the current drive speed).
Is equivalent to Similarly, the differentiating circuit 611 calculates the differentiation by the time constant set in advance with respect to the reference temperature,
The differential voltage obtained in step 7 is applied to obtain a voltage as a differential gain in the vertical direction. The voltage obtained by the differentiating circuit 611 corresponds to a vertical speed difference (difference between a target driving speed and a current driving speed).

As described above, the V / V 608 and 609 and the differentiating circuits 610 and 611 set the proportional and differential gains as the basic gain with respect to the reference temperature in each of the horizontal and vertical directions.

A memory 103 composed of an AM or the like, and C for displaying the calculated target position data and the detection position data of the correction lenses 31 and 32 stored in the memory 56 of the camera 1 described later.
A display unit 104 such as an RT, a read command generation unit 105 for outputting the detected position data stored in the memory 56 to the external connection unit 13 of the camera 1, and the external connection unit 100 of the camera 1 , A transmission / reception unit 106 for communicating digital signals such as target position data, read commands, and detected position data at a predetermined communication speed.

In the image stabilization system including the camera with the image stabilization function according to the present embodiment, in order to improve the correction performance, in order to drive the correction lens driving system in an almost ideal state, gain adjustment, specifically, Is the HP shown in FIG.
Gain correction circuit 614, VP gain correction circuit 615, H
D gain correction circuit 616 and VD gain correction circuit 617
Need to be adjusted. In the present embodiment, the shake detection unit 4
The driving unit 6 is driven using a target position data group based on a specific function generated by the external inspection device 100 instead of the shake amount calculated by the shake detection unit 51 using the pixel data from , The positions of the correction lenses 31 and 32 actually driven are detected by the position detection unit 7.
By comparing the detected position data group obtained by the position detecting unit 7 with the target position data group, the driving characteristics of the driving unit 6 can be evaluated.

For example, since human hand movement is a relatively smooth motion, a target position data group based on the SIN waveform is input as a specific function, and the detected position data group obtained by the position detection unit 7 is used. If the reproduced waveform is close to the SIN waveform, the driving characteristics of the driving unit 6 (correction lenses 31 and 3)
2 position control / drive performance) can be evaluated to be quite good.

The target position data calculation unit 102 of the external inspection apparatus 100 calculates a target position data group based on an arbitrary function (waveform) such as a discontinuous step function that does not change smoothly, in addition to the SIN waveform. An arithmetic processing program is prepared so as to obtain. Alternatively, a plurality of types of functions (waveforms) are stored in advance, and the waveform selection unit 101
May be used to select one of the functions (waveforms).

When the target position data group is input from the external inspection apparatus 100, the target position setting unit 53 of the shake correction amount setting unit 5 sends a drive control circuit 61 of the drive unit 6 at a fixed time interval TM (for example, 500 μs). ) And the target position data is 1
Are output one by one. However, in general, the external connection unit 13 of the camera 1 and the transmission / reception unit 106 of the external inspection apparatus 100
Is extremely slower than the communication speed between the target position setting unit 53 of the shake correction amount setting unit 5 and the drive control circuit 61 of the drive unit 6, and requires several times or more. Therefore, it is impossible to directly transmit the target position data from the external inspection apparatus 100 to the drive control circuit 61 of the drive unit 6 via the shake correction amount setting unit 5.

Therefore, as described above, the external connection unit 13
Is configured as an independent third microprocessor unit (μC3) having a different drive clock and mainly for communication with the external inspection apparatus 100. The target position data group transmitted from the transmission / reception unit 106 of the external inspection device 100 is temporarily stored in the memory 56 after being received by the external connection unit 13 of the camera 1. Then, the data is read from the memory 56 at the above-mentioned fixed time interval TM and transmitted to the drive control circuit 61.

When one target position data is output to the drive control circuit 61, either the horizontal actuator 62 or the vertical actuator 63 is driven, and either the horizontal correction lens 31 or the vertical correction lens 32 moves. As a result, the position after movement of either the horizontal correction lens 31 or the vertical correction lens 32 is detected by either the horizontal position detection unit 71 or the vertical position detection unit 72, and the position data input unit 57 outputs A
After the / D conversion, it is stored in the memory 56 as detection position data. The (horizontal) target position data for driving the horizontal actuator 62 and the (vertical) target position data for driving the vertical actuator 63 are output alternately.

The detection position data of the correction lenses 31 and 32 detected by the position detection unit 7 is also used for the predetermined time interval TM.
Therefore, it is impossible to directly transmit to the external inspection apparatus 100 via the position data input unit 57 or the like. Therefore, after being taken in by the position data input unit 57 and subjected to A / D conversion, it is temporarily stored in the memory 56. Then, when the external connection unit 13 receives the read command from the external inspection device 100, it is read from the memory 56 at a communication speed lower than the predetermined time interval TM and transmitted to the external inspection device 100.

Here, the target position data and the detected position data have a one-to-one correspondence and are the same. If the target position data group and the detected position data group are stored in different areas of the memory 56, the required storage capacity of the memory 56 becomes enormous. On the other hand, since the target position data group is stored by the external inspection device 100 or can be generated at any time, the target position data group is no longer stored in the memory 5 after being transmitted to the drive control circuit 61.
6 need not be stored. Therefore, the required storage capacity of the memory 56 can be halved by storing the A / D-converted detected position data in the area storing the transmitted target position data.

When transmission of all the detected position data stored in the memory 56 is completed, the external inspection apparatus 100
The target position data group transmitted first or the function (waveform) based on the target position data group is displayed on the display unit 104, and the detected position data group transmitted from the external connection unit 13 of the camera 1 is displayed on the same screen. The function (waveform) reproduced based on this is displayed. By comparing the two, the position control and drive performance of the correction lenses 31 and 32 by the drive unit 6 are evaluated. As described above, the closer the two are, the better the drive characteristics of the drive unit 6 are. If the two are so far apart and the error cannot be tolerated,
The gain adjustment volume and the like (not shown) of the HP gain correction circuit 614, the VP gain correction circuit 615, the HD gain correction circuit 616, and the VD gain correction circuit 617 shown in FIG. 4 are adjusted to correct the target position data group again. The data is transmitted to the control circuit 61 to drive the correction lenses 31 and 32, and the obtained detection position data is reevaluated.

Next, the operation of the present embodiment will be described with reference to the flowcharts shown in FIGS. When the main switch (not shown) of the camera 1 is turned on (#
1), the external connection unit 13 (the third microprocessor unit (μC3)) determines whether the switch S3 is on (# 3). As described above, when the connection terminal of the external inspection device 100 or the cable or the like connected to the external inspection device 100 is connected to the external connection terminal 14 of the camera 1, the switch S3 is turned on. Therefore, when the switch S3 is off (NO in # 3), the external connection terminal 1 of the camera 1
Since the external inspection device 100 is not connected to 4, the external connection unit 13 does nothing, and the first and second microprocessor units (μC1 and μC2) execute a normal camera sequence (# 5). Since the ordinary camera sequence is known, the description thereof is omitted.

On the other hand, when the switch S3 is ON (YES in # 3), since the external inspection apparatus 100 is connected to the external connection terminal 14 of the camera 1, the external connection unit 13 (the third microprocessor unit (μC3 )) And the second microprocessor unit (μC2) prepare for execution of the test sequence (# 7).

The external connection unit 13 determines whether the signal transmitted from the external inspection device 100 is a "memory content update command"(# 9). In the case of the “memory content update command”, the external connection unit 13 deletes the data already stored in the memory 56, and thereafter sets the target position data group (the total number of data is n) transmitted from the external inspection apparatus 100. ) Is newly stored in the memory 56 (memory content update (# 1
1)).

If the instruction is not a “memory content update command” in # 9 and if the memory content is updated in # 11, the external connection unit 13 determines whether the signal transmitted from the external inspection apparatus 100 next is the operation of the correction lens driving system. It is determined whether or not it is an “evaluation start command” for starting the evaluation of the characteristics (# 13).
In the case of the “evaluation start instruction”, the external connection unit 13 transmits the “evaluation start instruction” to the second microprocessor unit (μC2).
To the second microprocessor unit (μC

5).

Next, the second microprocessor unit (μC2) waits for a transmission timing at predetermined time intervals (for example, 500 μs) (# 17), and reads (horizontal) target position data from the memory 56 (# 19). ), (Lateral) target position data is output to the drive control circuit 61 (# 2)
1). The drive control circuit 61 drives the lateral actuator 62 based on the input (lateral) target position data (# 2).
3) Yes. The lateral position detecting unit 71 includes a lateral actuator 62
The position of the lateral shake correction lens 31 driven by the above is detected (# 25), and (lateral) detected position data (analog data) corresponding to the position is transmitted to the position data input unit 57 (# 27). The position data input unit 57 transmits the (horizontal)
A / D conversion of the detected position data is performed (# 29), and the memory 56
Is stored in the area where the (horizontal) target position data is stored (# 31).

When sampling of one piece of detected position data for one piece of target position data relating to the lateral shake correction lens 31 is completed, the second microprocessor unit (μC2) waits for transmission timing at predetermined time intervals (# 33), the (vertical) target position data is read from the memory 56 (# 35), and the (vertical) target position data is output to the drive control circuit 61 (# 21). Drive control circuit 61
Drives the vertical actuator 63 based on the input (vertical) target position data (# 39). The vertical position detector 72 detects the position of the vertical shake correction lens 32 driven by the vertical actuator 63 (# 41), and outputs (vertical) detected position data (analog data) corresponding to the position to the position data input unit 57. (# 43). The position data input unit 57 converts the transmitted (vertical) detected position data into an A / D signal.
It is converted (# 45) and stored in the area of the memory 56 where the (vertical) target position data is stored (# 47).

When sampling of one piece of detected position data for one piece of target position data relating to the vertical shake correction lens 32 is completed, the second microprocessor unit (μC2) subtracts two from the number n of target position data (# 4
9) It is determined whether or not n = 0, that is, whether or not the detected position data has been sampled for all target position data (# 51). If n = 0, the flow returns to step # 17 to sample (horizontal) detected position data for the next (horizontal) target position data.

If n = 0 (YES in # 53) and # 1
3, when the signal from the external inspection device 100 is not the “evaluation start command”, the external connection unit 13
It is determined whether the signal transmitted next from 0 is a "memory content read command"(# 55). In the case of the “memory content read command”, the external connection unit 13 sequentially reads the detection position data stored in the memory 56 (# 5).
5), and transmits it to the external inspection device 100 (# 57).

Further, the external connection unit 13 determines whether the signal transmitted next from the external inspection apparatus 100 is an “end command” indicating the end of the inspection sequence (# 5).
9) In the case of the “end instruction”, the test sequence of the second microprocessor unit (μC2) is terminated, and then the test sequence itself is terminated (# 61). On the other hand, if it is not the “end command” (NO in # 59), the external connection unit 13 returns to # 9 and waits for the next signal to be transmitted from the external inspection device 100. As described above, the inspection sequence on the camera 1 side ends.

Next, an inspection sequence in the external inspection apparatus 100 will be described. As described above, the memory 56
Is used for both the storage of the target position data and the storage of the detected position data after the correction lens is driven. Therefore, once the operating characteristics of the correction lens driving system are evaluated, the memory 56 is stored in the memory 56. Indicates a detection position data group. Here, when the operation characteristics of the correction lens drive system are evaluated again, the contents stored in the memory 56 must be updated to the target position data group. Therefore, the inspection sequence must be performed in the order of "update of the contents of the memory 56", "evaluation of the operation characteristics of the correction lens driving system", and "reading of the stored contents of the memory 56". The control program of the external inspection device 100 is also performed according to this procedure.

As shown in FIG. 13, when the inspection sequence is started (# 101), first, a function (waveform) for driving the correction lens driving system is selected (# 103). The selected function preferably includes a SIN function, a step function, and the like. Here, it is assumed that the SIN waveform has been selected.

Next, the external inspection apparatus 100 calculates a target position data group transmitted to the drive control circuit 61 at the predetermined time intervals TM in order to drive the correction lens drive system with the SIN waveform (# 105). ). Each target position data is
For example, the calculation is performed based on lens center position data, lens end position data, and the like stored in a ROM or the like provided in the first or second microprocessor unit (μC1, μC2) of the camera 1. These lens position data are transmitted to the external inspection device 1 via the external connection unit 13 of the camera 1.
Sent to 00. Note that by using the command “memory content read command” in FIG. 11, the data can be read in advance.

When the target position data outside the drivable range limited by the both end positions of the lens is transmitted to the drive control circuit 61, there is a possibility that a load exceeding the standard is applied to the actuators 62 and 63. Therefore, the program is limited so that target position data outside the drivable range is not calculated. The calculated target position data group is
The data is stored in the memory of the external inspection apparatus 100 for comparison with the detected position data group read out from the memory 56 of the camera 1 later (# 107).

When all the target position data are calculated and stored, the external inspection apparatus 100 transmits a “memory content update command” to the external connection unit 13 of the camera 1 (# 10).
9). When the preparation for updating the content of the memory 56 on the camera 1 side is completed, the external inspection apparatus 100 collectively sends the external connection unit 13 one group at a time in the order of (horizontal) target position data group and (vertical) target position data group, for example. Transmitted to the user (# 111).
As described above, since the communication speed between the external inspection device 100 and the external connection unit 13 of the camera 1 is much slower than the fixed time interval TM, each transmitted target position data is transmitted from the external connection unit 13. The data is directly written and stored in the memory 56. FIG. 14 shows an example of the target position data format.

When all the target position data are stored in the memory 56, the preparation for evaluating the operating characteristics of the correction lens driving system is completed. Therefore, the external inspection device 100 transmits an “evaluation start command” to the external connection unit 13 of the camera 1 (# 113). When receiving the “evaluation start command”, the second microprocessor unit (μC
2) corresponds to # in the flowcharts shown in FIGS.
Steps 15 to # 51 are executed.

When all the detected position data are stored in the memory 56, the external inspection device 100 transmits a “memory content read command” to the external connection unit 13 of the camera 1 (# 115). In response to the "memory content read command",
The external connection unit 13 connects the external inspection device 100 with the memory 5.
6. Send the detected position data stored in 6 one by one,
The external inspection device 100 receives and stores the detected position data group (# 117).

When all the detected position data are received, the external inspection apparatus 100 compares the target position data group stored in the memory with the received detected position data group (# 11).
9). For comparison, the detected position data group is converted into data at the same level as the target position data group using the design values. First, the center position data of the target position data group and the detected position data group are matched. Then, the range in which the respective data changes is obtained from the end position data, and the two are compared to obtain the change amount (correction coefficient) K of the target position data with respect to the unit change amount of the detected position data.

Here, the center position data of the target position data group is CDA, and both end position data are LPDA and LDA, respectively.
MDA. The center position data of the detection position data group is DAD, and both end position data are LPAD and LAD, respectively.
MAD.

The possible range of the target position data group is LPD
A-LMDA, and the possible range of the detected position data group is LPAD-LMAD (however, all are set to design values). LPDA and LPAD correspond, LMDA and LM
It is assumed that AD corresponds. These two ranges are
There is a relationship between the target position and the current position with the correction lenses 31 and 32 interposed therebetween, and both are the drivable range of the correction lenses 31 and 32. Therefore, the two should originally match. The change amount K of the target position data with respect to the unit change amount of the detected position data is expressed by the following (Equation 4).

[0092]

(Equation 4)

Assuming that certain data in the detected position data group is a PAD, and data obtained by converting the PAD to data at the same level as the target position data group is a PDA, the PDA is expressed by the following (Equation 5).

[0094]

(Equation 5)

As described above, by converting the detected position data group into a signal of the same level as the target position data group, it is possible to directly compare the two. When the conversion of the detected position data group is completed, the external inspection apparatus 100 converts the converted detected position data group and target position data group into C
It is displayed on a display unit such as an RT. Here, the operator compares the displayed detected position data group and the converted target position data group, and adjusts the gain of the drive control circuit 61 and reevaluates the drive characteristics of the correction lens drive system after the gain adjustment. The presence or absence of sex is determined (# 121). If it is necessary to re-evaluate the gain adjustment and drive characteristics, the process returns to step # 103 and the above-described inspection sequence is executed again. On the other hand, if no gain adjustment is required,
The external inspection device 100 transmits an “end command” to the external connection unit 13 of the camera 1 (# 123), and ends the inspection sequence (# 125).

Note that, contrary to the above description, the target position data group may be converted into data at the same level as the detected position data group. In the above calculation, the center position data CAD and the both end position data LPAD and LM of the detected position data group are used.
Although the design value is used as AD, an actual measured value may be used instead. As a method of measuring each data, the correction lenses 31 and 32 are reciprocated a plurality of times between both end positions, and the detection position detection data from the position detection unit 7 is displayed and measured. A method of measuring the output waveform by using an oscilloscope or the like can be considered.

In the above embodiment, the external connection unit 13
Are connected to an independent third microprocessor unit (μC
Although 3) was used, the present invention is not limited to this, and the second microprocessor unit (μC2) constituting the shake detection unit 4 and the shake correction amount setting unit 5 may have the function of the external connection unit 13. May be configured.

Further, in the above embodiment, a camera, particularly a still camera using a silver halide film as a recording medium, has been described as an example of the optical apparatus using the present invention. However, the present invention is not limited to this. Needless to say, the present invention can be applied to all devices having a shake correction function, such as a camera using a recording medium other than a film, such as a video camera, and binoculars.

[0099]

As described above, according to the shake correction function inspection system of the present invention, the shake correction means for correcting the shake, the driving means for driving the shake correction means, and the shake correction means are provided. Control means for controlling, position detection means for detecting the position of the shake correction means, inspection means for inspecting the driving characteristics of the drive means, and a pseudo shake signal between the inspection means and the control means. A communication means for communicating the detected position signal between the means and the position detecting means, and a storage means for temporarily storing the pseudo shake signal and the detected position signal. Without being transmitted, a pseudo shake signal (target position data) equivalent to a case where vibration is actually given to the optical device is transmitted from the inspection means outside the optical apparatus to the control means via the communication means, and the pseudo shake signal is transmitted to the control means. Base There controls the drive means can drive the actual correction means (correction lens). Further, the position of the correction lens actually driven is detected by the position detection unit, and a detection position signal (detection position data) corresponding to the position of the correction lens is transmitted to the external inspection unit via the communication unit, and the external inspection is performed. By comparing the pseudo shake signal transmitted by the means and the detected position signal received, the driving characteristics of the driving means can be known. As a result, the inspection and adjustment of the correction lens drive system can be performed without actually applying vibration to the optical device, and the inspection and adjustment can be made extremely simple and easy. Further, since no vibration is given to the optical device, there is no error caused by improper fixing of the optical device to the vibration table.

The signal to be communicated is temporarily stored in the storage means (R
AM, etc.), it is possible to adjust the difference in signal communication speed between the external inspection means and the control means and between the external inspection means and the position detection means.

Further, by generating a signal corresponding to an arbitrary vibration waveform by the inspection means, it is possible to perform inspection and adjustment using a vibration waveform which cannot be realized by a method of actually applying vibration to an optical device using a conventional vibration table. It becomes possible.

The storage means sequentially transmits the pseudo shake signal transmitted from the inspection means from each address to the driving means at a predetermined timing, and sequentially transmits the detected position signal from the position detection means to the pseudo shake signal. By sequentially storing the data at the corresponding addresses, the required storage capacity of the storage unit can be reduced. Further, if there is room in the capacity of the storage means, more position signals may be detected than the total number of pseudo shake signals.

According to the optical apparatus with a shake correcting function of the present invention, a shake correcting lens inserted into a part of the image pickup optical system, a driving unit for driving the shake correcting lens, and a position of the shake correcting lens are detected. And a communication means for communicating a predetermined signal between the position detection means for performing the detection and the inspection means provided outside the optical apparatus, and the driving means using the pseudo shake signal input from the inspection means via the communication means. Control means for driving and driving the driving means, and outputting a detection position signal corresponding to the position of the shake correction lens detected by the position detection means to the inspection means. By connecting to the shake correction function inspection device, it is possible to adjust the operating characteristics of the shake correction mechanism without actually applying vibration to the optical device.

Further, according to the shake correction function inspection method of the present invention, a shake correction means for correcting shake, a driving means for driving the shake correction means, a control means for controlling the shake correction means, and a shake A pseudo-vibration signal is input to a device including a position detection unit that detects the position of the correction unit, and the vibration correction unit is driven by the driving unit using the pseudo-vibration signal, and the position is detected by the vibration correction unit by the position detection unit. And
Since the driving characteristics of the driving unit are inspected using the detected position signal, the vibration-correcting function, particularly the driving characteristics of the vibration-correcting lens and the like can be inspected without actually vibrating the device having the vibration correcting function, Inspection and adjustment can be made extremely simple and easy.
