[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement in an optical apparatus with an image blur correction function that is used by being held or supported by a support member.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there has been proposed an apparatus for performing image stabilization by suppressing vibration due to camera shake correction, that is, camera shake or the like, including a camera. A typical one of the shake correction methods used in cameras and the like is that an imaging surface is driven by driving part or all of the photographing optical system based on camera shake information detected by a shake detection sensor. The above image blur is suppressed. As this type of image blur correction apparatus, for example, JP-A-9-43658 can be cited.
[0003]
However, the conventional image shake correction device generally selects a shake detection sensor or a shake correction optical system corresponding to the shake vibration having a frequency distribution similar to that of the hand shake vibration, or the above-described sensor, The response frequency band of the drive mechanism is set. Accordingly, when such an image blur correction apparatus is used while attached to a support member such as a tripod, the following drawbacks occur.
[0004]
1) Even when shake correction is almost unnecessary, the shake correction mechanism operates and power consumption increases.
[0005]
2) In a still camera, a quick return mirror or shutter mechanism at the time of release causes a high-frequency impact although it is a minute displacement amplitude, which may cause an erroneous output of the shake detection sensor.
[0006]
In this case, the shake correction mechanism performs shake correction that is not related to camera shake, and promotes image shake.
[0007]
3) Even when there is no shake, the low-frequency drift signal (fluctuation) output from the vibration detection means causes the shake correction mechanism to perform shake correction that is not related to camera shake, thereby promoting image shake. End up.
[0008]
In order to eliminate these drawbacks, if it is detected that the image blur correction device is attached to a support member such as a tripod, image blur correction drive is prohibited, or the characteristics of image blur correction control are changed. A technique for improving the above-mentioned disadvantages 1) to 3) is disclosed. For example, JP-A-4-56831 discloses a method for prohibiting image blur correction driving, and JP-A-4-328534 discloses a method for changing the characteristics of image blur correction control.
[0009]
Here, the correction for the shake of the high frequency minute amplitude caused by the mechanical action of the shutter member at the time of the release described in the above 2) will be described.
[0010]
Usually, the camera shake frequency band of the photographer is about 1 to 15 Hz, and if this frequency is within this range, the current sensor (for example, vibration gyroscope) and the correction optical system (for example, shift correction optical system) can sufficiently follow. is there. However, in a camera having a focal plane type shutter or the like, a frequency of about 100 to 200 Hz is generated by the traveling of the front curtain and the rear curtain, and the current sensor and correction system can sufficiently follow this frequency. I can't say that.
[0011]
FIG. 5 shows the state of the shake waveform during the shutter running when the camera is held by hand, and the original shake waveform shown in (c) at the timing of the start of the front curtain running shown in (a). Decreases rapidly in the downward direction, and this waveform increases rapidly in the upward direction at the timing when the first curtain travel is completed.
[0012]
On the other hand, the motion output of the actual sensor and the correction system is delayed with respect to the original shake as shown in (d), and the resulting shake on the actual image plane is shown in (e). As described above, it becomes very large until a predetermined time elapses from the start of traveling of the front curtain. Similarly, in the case of rear curtain travel, shake occurs in synchronization with the start of rear curtain travel and the end of rear curtain travel shown in FIG. Since it is close to completion, the impact is less than that of the front curtain.
[0013]
The effect of such shutter shake is reduced when a low-speed shutter is used, since the proportion of time during which this effect occurs is reduced compared to the overall exposure time, and the problem is eliminated. In the case of a higher-speed shutter, the exposure time itself is reduced. There is no problem in this case because it is short. Therefore, it becomes a big problem with a medium-speed shutter whose shutter speed is about 1/60 to 1/250 seconds.
[0014]
Therefore, there is a method as described in JP-A-9-33971 for such a problem. This includes a storage unit that stores a signal corresponding to a predetermined vibration state of the device when the mechanical action unit of the device is in a predetermined state, an output of the vibration detection unit, and a predetermined vibration stored in the storage unit. A signal forming unit for adding a signal corresponding to the state to form a signal for preventing the image blur correction operation, and adding the signal stored in the storage unit and the output of the vibration detecting unit to An appropriate signal that can properly operate the shake correction means is formed. Specific control of the method will be described below.
[0015]
First, the state of the shake, the state of the shake signal, etc. when driving the shutter will be described with reference to the timing chart of FIG. The timing chart of FIG. 6 shows fluctuations in the actual shake state, shake sensor output, and the like accompanying the shutter front curtain and rear curtain drive. In this figure, (a) is the shutter front curtain drive status, (b) is the shutter rear curtain drive status, (c) is the actual camera shake status, (d) the shake sensor output and the displacement of the correction system, ( e) is correction data to be described later, (f) is a result of adding the shake sensor output and the correction data, and displacement of the correction system operating in response thereto, and (g) is the correction system as shown in (f). The remaining image plane amounts on the image plane when operated are shown.
[0016]
As shown in FIG. 6 (c), when the driving of the front curtain is started, the camera body has a shake that is much faster than the camera shake downwards. Shake occurs. This is due to the fact that the camera body is moving due to the reaction of the front curtain running and stopping.
[0017]
On the other hand, as shown by the solid line in (d), the actual shake sensor output is the occurrence timing and peak timing of the shake (the delay t from the original shake peak to the sensor output peak).₁ ) Are delayed due to the deterioration of the high frequency performance of the vibration sensor itself. Furthermore, the drive displacement when the correction optical system is driven based on the output of the shake sensor, that is, the output of the correction optical system position detection means (not shown) is as shown by the dotted line in FIG. This waveform is more delayed than the shake sensor output.Has occurredHowever, this is due to the deterioration of the high frequency performance of the correction system itself.
[0018]
Therefore, consider adding an arbitrary waveform that maintains the level after a certain monotonous increase as shown in FIG. 6E to the sensor output. The result of adding this waveform to the shake sensor output is shown in FIG. 6 (f). As is apparent from the comparison with FIG. 6 (d), during the period Δt from the completion of the leading curtain travel, (c In the case of (d), the correction is made in the reverse direction with respect to the original waveform shown in (), whereas in the case of (f), the actual fluctuation of (c) is not followed completely. Correction in the same direction asHas been doneI understand that. The final shake amount on the image plane obtained by such a correction operation is shown in FIG. 6G. Compared with FIG. 5E, the final shake amount is shown at the timing before the shutter is fully opened. Although the amount of correction remains large, the ratio that contributes to the actual exposure during this period is small compared to the fully opened state, whereas after the shutter is fully opened,FIG. 5 (e)Compared to the above, the remaining amount of image blur correction is much smaller, and the blur in actual exposure can be reduced.
[0019]
In the case of the rear curtain travel, the shake waveform as shown in FIG. 6C is generated as in the case of the front curtain travel. However, since the shutter curtain is in the closing direction, the influence on the actual exposure is Therefore, the effect on the shooting result is small.
[0020]
By performing the shake correction as described above, a proper image can be obtained even when a shake that cannot be properly detected and corrected by a normal sensor or a correction system, for example, a high-frequency shake as described above occurs. This means that shake correction can be performed.
[0021]
[Problems to be solved by the invention]
However, the high-frequency vibration generated by the action of the mechanical action part of the equipment as described above is slightly different depending on whether the equipment is supported by hand or installed on a support member such as a tripod. I understand.
[0022]
FIG. 7 simply shows an example of a shake waveform before and after exposure that occurs in the direction of gravity when a single-lens reflex camera is held by hand at a normal shooting position and when a tripod is supported as an example of an optical apparatus with an image shake correction function. FIG.
[0023]
According to this, at the time of hand-held support, first, shake due to mirror up (about 30 Hz) occurs, then shake due to shutter front curtain travel (about 100 to 200 Hz) occurs, and shake due to shutter rear curtain travel after the exposure time ( About 100 to 200 Hz) occurs, and finally, shake due to mirror down (about 30 Hz) occurs. In addition, since it is in a hand-held support state, hand shake (about 1 to 15 Hz) is further added.
[0024]
Next, when focusing on the tripod support, a shake (approximately 10 to 30 Hz) due to the mirror-up is generated in the same manner. However, the shake due to the next shutter front curtain running and the shake due to the shutter rear curtain running after the exposure time are almost the same. It has not occurred. Finally, shake (about 10 to 30 Hz) due to mirror down occurs again. Further, since the camera is in a tripod support state, there is no camera shake (about 1 to 15 Hz), and it exists only during the exposure (even after the exposure) due to the after-effect of the shake caused by the mirror up.
[0025]
Thus, it can be seen that the shake that occurs before and after the exposure slightly differs depending on the support state. In the tripod support state, resonance by the tripod appears clearly due to the mirror-up operation, so the spring property is strong and the viscosity is weak. In the hand-held support state, the spring property is weak and the viscosity is strong. This is considered to be related to the difference in the support state system.
[0026]
Therefore, image shake correction means is provided for high-frequency shake that is generated when the mechanical action part of the equipment acts when the equipment is supported by the photographer's hand and cannot be properly detected by the vibration detection means. If an optical device with an image blur correction function provided with a proper operation control means for controlling the device to operate more properly is installed on a tripod or the like and used, the proper operation control optimized in a handheld support state is performed. In other words, operation control that is not suitable for installation on a tripod or the like is performed, and as a result, there is a problem that image blur may be enlarged. Specifically, correction data optimized during hand-held support as shown in FIG. 6E is added.
[0027]
(Object of invention)
An object of the present invention is to prevent the image blur from being enlarged on the contrary by performing an appropriate operation control when being supported by a hand while being attached to a support member. It is an object of the present invention to provide an optical apparatus with an image blur correction function that can be used.
[0028]
[Means for Solving the Problems]
  To achieve the above object, the present inventionOptical equipmentA vibration detection unit that detects vibration applied to the optical device, a correction unit that corrects image blur due to the vibration, and the optical device.When driving the front curtain and the rear curtain of the focal plane shutterSpecific vibration component generated inStores correction data for correcting image blur caused by, The signal from the vibration detecting means and theCorrection data andImage blur correction control means for controlling the driving of the correction means based on theHave,The image blur correction control means isBased on the signal from the vibration detection means, the support state of the optical deviceJudgment,When it is determined that the support state is support by a photographer, the driving of the correction unit is controlled based on a signal obtained by adding the correction data to the signal from the vibration detection unit, and the support state is determined by a tripod.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on illustrated embodiments. In the present embodiment, a case where the present invention is applied to a single-lens reflex camera and its interchangeable lens will be described as an optical apparatus with an image blur correction function.
[0030]
FIG. 1 is a block diagram showing an electrical configuration of a camera according to an embodiment of the present invention. In FIG. 1, reference numeral 101 denotes various controls such as image blur correction control, support state determination, proper operation control, and operation prohibition. Is a lens microcomputer that receives communication from the camera body through communication contacts 109c (for clock signal) and 109d (for body → lens signal transmission), and according to the command values, the shake correction system 102 and the focus drive system 104 The diaphragm drive system 105 is operated.
[0031]
The shake correction system 102 includes a shake sensor 106 that is an example of a shake detection unit that detects shake, a position sensor 107 for detecting a correction lens displacement, and a lens microcomputer 101 based on outputs of the shake sensor 106 and the position sensor 107. Is a shake correction drive system 108 that performs a shake correction operation by driving the correction lens in accordance with the control signal calculated in (1). Reference numeral 124 (SWIS) denotes an anti-vibration switch for selecting the shake correction operation. When the shake correction operation is selected, the anti-vibration switch 124 is turned ON.
[0032]
The focus drive system 104 performs focusing by driving a focus adjustment lens according to a command value from the lens microcomputer 101. The aperture driving system 105 performs an operation of reducing the aperture to a set position or returning to an open state according to a command value from the lens microcomputer 101. The lens microcomputer 101 also communicates information about the state in the lens (focus position, aperture value state, etc.) and information about the lens (open aperture value, focal length, data necessary for distance calculation, etc.) 109e for communication. It is also transmitted from the lens (for body signal transmission) to the body side.
[0033]
The lens microcomputer 101, the shake correction system 102, the focus drive system 104, and the aperture drive system 105 constitute a lens electrical system 110. The lens electrical system 110 is supplied with power from an in-camera power supply 118 through a power supply voltage contact 109a and a ground contact 109b.
[0034]
Inside the camera body, as a camera body electrical system 111, a distance measurement unit 112, a photometry unit 113, a shutter unit 114, a display unit 115, other control units 116, and management and exposure of these operations such as start and stop A camera microcomputer 117 that performs calculation, ranging calculation, and the like is incorporated. The power for the camera electrical system 111 is also supplied from the camera power supply 118. Reference numeral 121 (SW1) is a switch for starting photometry and distance measurement preparation operations, and 122 (SW2) is a release switch for starting a release operation, and these are generally two-stage strokes. The switch is configured such that the switch 121 is turned on by the first stroke of the release button and the release switch 122 is turned on by the second stroke. Reference numeral 123 (SWM) denotes an exposure mode selection switch. The exposure mode can be changed by turning the switch ON or OFF, or by simultaneously operating the switch 123 and other operation members.
[0035]
FIG. 2 is a flowchart showing a specific operation in the lens microcomputer 101, which will be described below.
[0036]
The image blur correction operation is performed by an interrupt process that occurs at regular intervals. Then, control in the first direction, for example, the pitch direction (vertical direction) and control in the second direction, for example, the yaw direction (lateral direction) are alternately performed. When the interruption occurs, the lens microcomputer 101 starts the operation from step # 101 in FIG.
[0037]
In step # 101, it is determined whether the current control direction is the pitch direction or the yaw direction. If it is in the pitch direction, the process proceeds to step # 102, a data address is set so that various flags, coefficients, calculation results, etc. can be read and written as pitch data, and the process proceeds to step # 104. If it is in the yaw direction, the process proceeds to step # 103, and a data address is set so that various flags, coefficients, calculation results, etc. can be read and written as yaw data, and the process proceeds to step # 104.
[0038]
In step # 104, the shake sensor 106 is used.AsThe output of the angular velocity sensor is A / D converted, and the result is stored in the predefined AD_DATA in the RAM. In the next step # 105, it is determined whether an instruction to start image blur correction has been issued. For example, image blur correction is started by a logical product of ON of the switch SWIS and ON of the switch SW1. If a start instruction has been given, the process proceeds to step # 106, and if no instruction has been given, the process proceeds to step # 118. Here, an instruction to start image blur correction is given, and it is assumed that the process proceeds to step # 106.
[0039]
In step # 106, a flag indicating whether or not the determination time for determining the support state has elapsed is determined. If the predetermined time has not elapsed, the determination time elapse flag is L level, so the process proceeds to step # 107, and the support state determination calculation is performed. Details will be described based on a flowchart of FIG. 3 described later. Thereafter, the process proceeds to step # 108. If the predetermined time has elapsed, the determination time elapse flag is H level, so that the support state determination calculation is not performed and the process proceeds from step # 106 to step # 108. Here, it is determined whether or not the support member is detected. Make a decision. If not detected in the calculation of step # 107, the support member detection flag is at L level, so the process proceeds to step # 109. If detected, the support member detection flag is at H level, and the process proceeds to step # 112. .
[0040]
When the process proceeds to step # 109, a high-pass filter (HPF) calculation for normal image stabilization control is performed here. Then, in the next step # 110, integral calculation for normal image stabilization control is performed and converted into an image shake angular displacement signal (BURE_DATA). In the subsequent step # 111, the shake correction system 100 is used for the high-frequency shake that cannot be properly detected by the shake sensor 106 that is generated when the shutter operates when the camera is supported by the photographer's hand. An operation for forming a signal to be controlled so as to operate more appropriately is performed. Details will be described based on a flowchart of FIG. 4 described later.
[0041]
If the support member is detected in step # 108, the support member detection flag is at the H level. Therefore, the process proceeds to step # 112 as described above, where the low-frequency vibration is small and the high-frequency vibration is large. Therefore, the cut-off frequency is set higher than the normal high-pass filter (HPF) calculation, and the low-frequency component is further reduced. Then, in the next step # 113, the image stabilization control at the time of detecting the support member is performed. This is because, for example, in the case of an image shake correction apparatus having a shift optical system, the integral signal is constant in order to perform control with the position of the optical axis eccentricity being constant, or an image in which the high frequency component is corrected more than the low frequency component. To perform shake correction control, the integration time constant is made smaller (integration signal = (BURE1_DATA)).
[0042]
Further, since the support member is being detected after step # 113, the above-described signal formation calculation for correcting the shutter shake in step # 111 is not performed.
[0043]
In the next step # 114, the output of the position sensor 107 that detects the position of the correction lens is captured and A / D converted (after conversion = PSD_DATA). Then, in the next step # 115, feedback calculation {(BURE (1) _DATA) − (PSD_DATA)} is performed. In the subsequent step # 116, phase compensation calculation is performed in order to obtain a stable control system. Although the phase compensation characteristic is kept as it is here, the phase compensation characteristic may be changed according to the support state. In step # 117, the calculation result obtained in step # 116 is output to an output port (not shown). The signal output from the output port is input to the shake correction drive system 108, whereby the correction lens is driven and image shake correction is performed.
[0044]
If the instruction to start image blur correction is not issued in step # 105, the process proceeds to step # 118 as described above, where high pass filter (HPF) calculation and integration calculation are initialized.
[0045]
Next, the support state determination calculation executed in step # 107 of FIG.ofThis will be described based on a flowchart.
[0046]
  First, in step # 201, a time measuring timer for determining the support state is started. In the next step # 202, a high-pass filter operation for quickly removing the DC component is performed in order to form a support state determination signal. However, the input signal is step # in FIG.104AD_DATA. In the subsequent step # 203, a low-pass filter operation is further performed to remove high-frequency noise (output signal = HANTEI_DATA). In step # 204, the peak hold calculation of the HANTEI_DATA signal is performed. That is, the maximum value (pitch: MAXDATAP, yaw: MAXDATAY) and minimum value (pitch: MINDATAP, yaw: MINDATAY) of the HANTEI_DATA signal are held and stored in the RAM.
[0047]
In the next step # 205, it is determined whether or not a predetermined calculation time for detecting the support member has elapsed. If it has not elapsed, the process ends. If it has elapsed, the process proceeds to step # 206, and the predetermined time has elapsed. Therefore, the determination time elapsed flag is set to H level. Here, it is finally determined whether or not the support member is attached. As a determination method, the amplitude is calculated from the maximum peak value (MAXDATA) and the minimum peak value (MINDATA) of the shake signal obtained in the above step # 204, and is compared with the threshold level to be attached to the support member. It is determined whether or not. In the next step # 207, the amplitude in the pitch direction (MAXDATAP−MINDATAP) and the amplitude in the yaw direction (MAXDATAY−MINDATAY) are calculated.
[0048]
In step # 208, it is determined whether the amplitude in the yaw direction is greater than or equal to the threshold level. If it is equal to or higher than the threshold level, it is determined that it is not attached to the support member because the shake amount is large, and the process proceeds to step # 211 and ends with the support member detection flag = L level. On the other hand, if it is less than the predetermined value, the process proceeds to step # 209, and determination is made in the other axial direction. That is, it is determined whether the amplitude in the pitch direction is equal to or higher than the threshold level. If it is equal to or higher than the threshold level, it is determined that it is not attached to the support member because the amount of deflection is large, and the process proceeds to step # 211 described above. It is determined that it is attached to the member, and the process proceeds to step # 210. In step # 210, the support member detection flag is set to H level and the process ends.
[0049]
In the support state determination calculation process, steps # 201 to # 201 are performed.# 205Is performed for each interruption until the predetermined time is reached, and steps # 206 to # 211 are performed only once for the final determination after the predetermined time has elapsed.
[0050]
Next, the signal formation calculation for high-frequency shake correction at the time of shutter driving executed in step # 111 of FIG. 2 will be described based on the flowchart of FIG. The timing at which the control is performed is as described in the conventional example (see FIG. 6).
[0051]
First, in step # 301, it is determined whether or not the camera switch SW2 (122 in FIG. 1) is turned on. If it is turned on, the process proceeds to step # 302, and if it is off, the process proceeds to step # 310.
[0052]
In step # 302, for example, it is determined whether the shutter speed is 1/60 second or more and less than 1/250 second. Here, the correction is performed only at the middle speed time at which the influence of the shutter shake is likely to occur. If the condition is satisfied, the process proceeds to step # 303, and if not, the process proceeds to step # 310. In step # 303, the timer is reset, and the process proceeds to step # 304.
[0053]
In step # 304, T₀ It is determined whether or not elapses. T₀ If not, the process proceeds to step # 305 where the high-frequency shake correction data output remains cleared to 0, and the data added to the sensor output (here, the integral signal) remains 0. T₀ If it has reached, the process proceeds to step # 306, and this time the timer value is T₁ It is determined whether or not the number is exceeded. T₁ If not, the process proceeds to step # 307, where high-frequency shake correction data is generated as shown in FIG. 6E, and this output is added to the shake sensor output (here, the integral signal). . Here T₀ Correction data that monotonously increases with a certain inclination over time is formed. The timer value is T₁ If it has passed, the process proceeds from step # 307 to step # 308, where the increase in the output of the high-frequency shake correction data generated in step # 307 is stopped, and the value is held thereafter during the exposure period.
[0054]
In the next step # 309, this time the timer value is T_Three It is determined whether or not the number is exceeded. T_Three If it has not elapsed, the process returns to step # 304, but if it has elapsed, the process proceeds to step # 310 to clear the high-frequency shake correction data output to zero. The data added to the sensor output (here, the integration signal) remains 0.
[0055]
According to the above embodiment, when the camera is used by being mounted on a tripod or the like, the photographer tries to correct the high-frequency shake that occurs when the camera's focal plane shutter acts with a handheld support. It is possible to prevent the image blur from being enlarged.
[0056]
(Modification)
In the above embodiment, an example is shown in which an angular velocity sensor is used as a shake sensor. However, any means that can detect shake, such as an angular acceleration sensor, an acceleration sensor, a speed sensor, an angular displacement sensor, or a displacement sensor, is used. It may be something like this.
[0057]
Further, as the correction means of the present invention, a shift optical system that moves the optical member in a plane perpendicular to the optical axis, a light flux changing means such as a variable apex angle, a thing that moves the photographing screen in a plane perpendicular to the optical axis, etc. Any image can be used as long as image blur can be corrected.
[0058]
Further, in the present invention, each component or part of the configuration of the claims or the embodiments may be provided in a separate device. For example, the shake detection device may be provided in the camera body, the shake correction device may be provided in the lens barrel attached to the camera, and a control device for controlling them may be provided in the intermediate adapter.
[0059]
Moreover, although the example applied to the camera is shown, if it is an optical apparatus which has the above subjects, it can apply similarly.
[0060]
【The invention's effect】
As described above, according to the present invention, the image blur is magnified on the contrary by performing an appropriate motion control when being supported by a hand although it is attached to a support member and used. Therefore, it is possible to provide an optical apparatus with an image blur correction function that can prevent the occurrence of the image blur.
