Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an anti-vibration camera provided with an anti-vibration system which detects vibration applied to a camera and corrects image deterioration due to the vibration by a correction optical means.

[0002]

2. Description of the Related Art The prior art to which the present invention is applied will be described below.

In modern cameras, all the important operations for photographing such as exposure determination and focusing are automated, so that even a person who is inexperienced in operating the camera is unlikely to make a mistake in photographing. However, it was difficult to automatically prevent only shooting failures due to camera shake.

Therefore, in recent years, a camera capable of preventing a photographing failure due to the camera shake has been actively researched, and in particular, a camera capable of preventing the photographing failure due to a camera shake of a photographer. Is under development and research.

The camera shake at the time of photographing is usually a vibration of 1 Hz to 12 Hz as a frequency. However, at the time of shutter release, even if such a camera shake occurs, it is possible to take a photograph without image shake. As a basic idea, it is necessary to detect the vibration of the camera due to the hand shake and displace the correction lens according to the detected value. Therefore, in order to be able to take a picture that does not cause image shake even if camera shake occurs, first it is necessary to accurately detect the camera vibration and secondly correct the optical axis change due to camera shake. Becomes

In principle, this vibration (camera shake) is detected by a vibration sensor for detecting angular acceleration, angular velocity, angular displacement, etc., and an output signal of the sensor is integrated electrically or mechanically to determine the angle. This can be done by mounting a camera shake detection unit that outputs displacement on the camera. Then, based on this detection information, the correction optical means for decentering the photographing optical axis is driven to suppress the image blur.

The drive direction (polarity) of p and 79y is the position detection element 78p,
When the output of 78y is set to be small (negative feedback), the driving force of the coils 79p and 79y causes the support frame 7 to be at a position where the outputs of the position detection elements 78p and 78y become substantially zero.

FIG. 23 is a block diagram showing the schematic arrangement of a camera equipped with the above-mentioned image stabilization system.

In FIG. 23, reference numeral 11 is a vibration detecting means composed of a shake detecting sensor such as the angular velocity detecting means of FIG. 19 and a sensor output arithmetic circuit for integrating the output of the shake detecting sensor and converting the output into shake and performing a predetermined amplification. Is. Reference numeral 12 denotes an image stabilization switching means composed of a sample hold circuit 12a and a differential circuit 12b. Since the sample hold circuit 12a is always sampling, the differential circuit 12b calculates the difference between two same outputs, and The output is zero. Reference numeral 17 denotes a release means provided in the camera body, and when the release button is half-depressed (switch SW1 is turned on), the exposure preparation means 42 for driving the lens for photometry, distance measurement and focus focusing is activated to release the release button. Press off (switch SW2 is on)
Then, the exposure means 116 for performing mirror up / down and shutter opening / closing operations.

Here, a switch SW is attached to the release means 17.
When the ON signal of 1 is generated, this signal is input to the sample hold circuit 12a of the image stabilization switching means 12 to put the sample hold circuit 12a in the hold state. Then, the differential circuit 12b sets the time to zero and starts continuous output of shake detection output (hereinafter, target value). This target value is input to the buffering means 13 including a known filter circuit composed of a resistor and a capacitor, and the buffering switching means 14 via the image stabilization sensitivity changing means 46 described later. The buffer switching means 14 normally connects the switch piece 14a to the terminal 14c. That is, the buffering means 13 is not interposed during the vibration isolation (the terminal 14b is in the non-connection state).

Reference numeral 15 is a drive means having the circuit configuration shown in FIG. 22, which receives the position detection output of the correction optical means 16 (outputs of the position detection elements 78p and 78y) and the coil 79.
Drive power is applied to p and 79y. The target value is input to the drive means 15 as a command signal, and the correction optical means 16 is driven and controlled faithfully to the target value.

Reference numeral 46 denotes an image stabilization sensitivity changing means for changing the amplification of the output of the buffer switching means 14 (first ratio setting). This amplification factor is changed by receiving the outputs of the zoom information output means 111 and the focus information output means 110.

In order to perform sufficient image stabilization, it is necessary to change the driving amount of the correction optical means 16 according to the focal length of the lens. That is, it is necessary to change the correction amount of the correction optical unit 16 with respect to the amount of camera shake according to the focal length.

This is a correction optical means 16 according to the focal length.
Eccentricity sensitivity (correction amount on the image plane with respect to the driving amount of the correction optical unit 16) is changed. For example, when the zoom is set to the tele side, the correction optical unit 16 with respect to the camera shake amount for sufficient image stabilization is performed. If the ratio of the driving amount is "1", sufficient vibration isolation cannot be performed unless the ratio is set to "1/4" when the zoom is wide. If this ratio is left at "1", the image stabilization amount becomes excessive when the zoom is wide, and conversely the image is vibrated.

Reference numeral 47 is a ratio changing means, which further amplifies and changes the amplification of the target value from the image stabilization sensitivity changing means 46 (drops the amplification rate to 2/3) (second ratio setting).
A differential circuit 47b for obtaining the difference between the output of the amplifier 47a and the target value of the image stabilization sensitivity changing means 46, and a sample hold circuit 47c and a sample hold circuit 47c for holding the output of the differential circuit 47b when the switch SW2 is on. The differential circuit 47d for obtaining the difference between the output and the target value of the image stabilization sensitivity changing means 46, the switch means for connecting the switch piece 47e to the terminal 47g only when the switch SW2 is turned on (usually connected to the terminal 47f, ratio change inhibiting means). When the output of 114 is input, it is always connected to the terminal 47g), and the driving means 15
The target value of the second ratio is switched until the switch SW2 is turned on, and the target value of the first ratio is switched while the switch SW2 is turned on. The differential circuits 47b and 47d and the sample hold circuit 47c hold the output of the sample hold circuit 47c when the switch SW2 is turned on, and store the difference between the output of the amplifier 47a and the target value (the output of the image stabilization sensitivity changing means 46). , The difference between the difference and the target value
Then, the continuity before and after the switching by the switch piece 47e at the time of the switch SW2 is maintained by obtaining the new target value.

The amplification factor of the amplifier 47a is further determined by the zoom information output means 111 and the focus information output means 110.
The output is variable when the zoom is tele, for example, the first ratio output is amplified to "2/3", and when the zoom is wide, it is amplified to "1/3".

That is, until the switch SW2 is turned on (until shooting), the target value is set to "2/1 /" of the true target value (first ratio).
3 ", the driving amount of the correction optical means 16 is reduced to save power, and the vibration proof accuracy is also reduced to enable fine framing (fine framing change does not prevent vibration. ing). Then, only during exposure (when the switch SW2 is on), sufficient image stabilization is performed to prevent image deterioration due to shake on the film surface.

Here, the switch SW2 is used when the zoom is tele.
If the second ratio is set to "1/3" of the first ratio until the ON state, the photographer cannot sense the image stabilization performance. However, when the zoom is wide, small camera shake cannot be felt from the beginning, so when looking through the viewfinder (from turning on the switch SW1 to turning on the switch SW2), only large shake should be prevented. May reduce the second ratio to "1/3" of the first ratio.

With the above structure, power saving can be expected.

The ratio change prohibiting means 114 has a function of prohibiting the change of the image stabilization based on the first ratio to the image stabilization based on the second ratio by the operation of the photographer. That is, the switch SW
Even when 1 is turned on, sufficient image stabilization is performed at the first ratio, and it is used when the subject is sufficiently observed.

The output of the ratio change prohibiting means 114 is input to the switch means 47e of the ratio changing means 47,
The switch means 47e is fixed to the terminal 47g. or,
The output of the ratio change prohibition means 114 is input to the ratio change prohibition display means 112, and displays that the ratio change is prohibited. The timer 2 (113) outputs for a fixed period after the switch SW2 of the release means 17 is turned on, and resets the ratio change prohibition means 114 at the falling edge. Therefore, the prohibition of changing the ratio is lifted for each shooting. Of course, the prohibition of changing the ratio can also be canceled by the operation of the photographer.

Next, how to stop the image stabilization will be described.

In FIG. 23, when the switch SW1 of the release means 17 is turned off, the sample hold circuit 12
a becomes the sampling state again, the output of the amplifier 12b becomes zero, and the image stabilization stops.

Here, the case where the buffer means 13, the buffer switching means 14 and the timer 3 (117) in FIG. 23 are not provided, that is, the case of the configuration of FIG. 24 will be described.

In the case of this configuration, the output of the image stabilization switching means 12 suddenly becomes zero from the shake target output when the switch SW1 is turned on. Therefore, the correction optical means 16 is rapidly driven toward the zero target value.

In FIG. 25, the time when the switch SW1 is turned off indicates the drive position of the correction optical means 16 in this rapid drive state, and such rapid drive causes an abrupt framing change and is uncomfortable for the photographer. is there. Therefore, the buffer means 13 is used as shown in FIG.

In FIG. 23, when the switch SW1 is turned off, the output of the image stabilization switching means 12 becomes zero. This zero output is also input to the buffer means 13, and the buffer means 13
The output of is gradually reduced to zero from the shake target when the switch SW1 is on (because the filter circuit is included).
Then, the timer 3 (11
Switch piece 14 of buffer switching means 14 only for a certain period of 7)
A is connected to the terminal 14b, and the output from the buffer 13 is set as the drive target value of the correction optical unit 16. That is, the correction optical means 16 slowly moves toward zero from the drive position immediately before the switch SW1 is turned off, as shown after the switch SW1 is turned off in FIG.

With such a configuration, the switch SW1
It also eliminates the discomfort when the power is off and saves power.

[0055]

However, as shown in FIG.
In the example of (b), after the switch SW1 is turned off, there is a period 61 in which the correction optical unit 16 is slowly driven to the center without performing image stabilization, and during this period, the correction optical unit 16 is driven without image stabilization. There is also a problem that it is a waste of electricity and that it does not give a good impression that only the framing flows after the vibration control is finished.

(Object of the Invention) The first object of the present invention is to shorten the time until the stop of the image stabilization and to achieve the power saving, and also to prevent the photographer from feeling the shaking of the screen when the image stabilization is stopped. It is to provide an anti-vibration camera.

A second object of the present invention is to provide an anti-vibration camera capable of further reducing image deterioration due to shake.

[0058]

According to the present invention, the image stabilization is continued even after a signal for stopping the image stabilization operation by the image stabilization system is input, and a constant drive range variable according to the focal length of the photographing lens,
Alternatively, an anti-vibration control means is provided to stop the anti-vibration when the correction lens of the correction optical means is inserted within a certain period of time, and the anti-vibration is continued even after the signal is input to stop the anti-vibration operation by the anti-vibration system. An anti-vibration control means for decreasing the anti-vibration suppression ratio of the anti-vibration system in a predetermined period, and a constant drive range variable by the focal length of the photographing lens after inputting a signal for stopping the anti-vibration operation by the anti-vibration system, or Is provided with anti-vibration stopping means for stopping anti-vibration when the correction optical means is turned on within a certain period of time, and the anti-vibration is continued even after a signal is input to stop the anti-vibration operation by the anti-vibration system. Anti-vibration control means for changing the anti-vibration frequency characteristic of the anti-vibration system within a predetermined period, and a constant drive range that is variable depending on the focal length of the taking lens after inputting a signal for stopping the anti-vibration operation by the anti-vibration system, or , Enter the correction optical means within a certain time. And when, providing a vibration damping stop means for stopping the anti-vibration, after antivibration stop signal input also will continue the anti-vibration during image stabilization, the correction optical means is within a predetermined drive range,
The image stabilization is stopped, or the image stabilization precision is gradually decreased within a fixed time after the image stabilization stop signal is input, so that the period in which only the correction optical unit is driven after the image stabilization is stopped is eliminated. Further, the constant drive range or the constant time is variable depending on the focal length of the photographing lens, that is, the range is widened or the time is lengthened when the zoom is wide.

Further, according to the present invention, the image stabilization control means for re-controlling the exposure control means within a predetermined time from the start of the exposure is provided, and when the deterioration of the image stabilization accuracy is predicted, the shutter is closed, the aperture is narrowed down, and the flash light is emitted. For example, the exposure control means is re-controlled.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on the illustrated embodiments.

FIG. 1 is a block diagram showing a schematic structure of an image stabilizing camera according to the first embodiment of the present invention, and blocks having the same functions as those in FIG.

In FIG. 1, the vibration-proof strength-off means 1 (11
In 8), counting is started from the ON input of the switch SW1 from the release means 17, and the output is stopped (the output falls) at time t ₄ (for example, 10 seconds). Also, the release means 17
The count is reset by the ON input of the switch SW2 from. That is, from the ON input of the switch SW1 to t
_{4 '(t 4'<t} 4) If there is on the input of the switch SW2 in between, will stop the output after the "t ₄ '+ t _4" (output falls) it.

A signal from a target value input stop means 122, which will be described later, is also input to the image stabilization strength off means 1 (118), and is reset by this signal input. The output of the image stabilization strength off means 1 (118) is input to the sample hold circuit 12a and the image stabilization forced off output means 123.

As a result, the sample hold circuit 12a
Becomes a hold state, and the target value starts to be output from the image stabilization switching means 12. When the output of the anti-vibration strength OFF means 1 (118) disappears after t ₄ (or t ₄ ′ + t ₄ ) has elapsed from the ON input of the switch SW1, the sample hold circuit 12a becomes the sampling state again, and the target value is reached. The output becomes zero and the correction optical means 16 is returned to the zero point. Further, the image stabilization strength OFF output means 123 outputs the output from the falling edge of the output of the image stabilization strength OFF means 1 (118), and the timer 1 (1
24) and this is input to the timer 3 (126). The timer 1 (124) stops the output after t ₁ (for example, 0, 3 seconds) time (a time sufficient for the correction optical means 16 to return to the zero point) from this input.

That is, the output of the timer 1 (124) is the locking means 125 (mechanical lock chassis 718, plunger 719, spring 720, mechanical lock arm 721, FIG. 20).
It is input to the locking screw 125).
Is the plunger 7 due to the falling output of timer 1 (124).
19 to drive the mechanical lock arm 721 protrusion 721a.
Is fitted into the hole 72d of the support frame 72 to lock the support frame 72. The locking means 125 is a switch SW1.
The plunger 719 is driven in response to the input of ON to release the lock. Further, the timer 3 (126) receives the output of the anti-vibration strength OFF output means 123, and t ₃ (for example, 1 second).
After a lapse of time (t ₃ > t ₁ ), the output to the drive coil interrupting means 130 is stopped.

The drive coil connecting / disconnecting means 130 uses the timer 3 (1
26), the coil of the correction optical means 16 and the drive means 15 are disconnected due to the output fall [the switch piece 130a and the terminal 130c are disconnected, and the switch 130a and the terminal 13 are disconnected.
0b (the other end of the coil) is connected to make the coil short-circuited].

That is, t ₄ (t
₄ '+ t ₄₎ while, if continued to vibration isolation, stop strong sexually antivibration for power saving, it engages a correcting optical unit 16, a short circuit coil. Here, it is the switch S that the anti-vibration strength OFF means 1 is reset by turning on the switch SW2.
The time just before exposure is t ₄ hours after W1 is turned on,
This is to prevent the anti-vibration from failing during exposure.

The vibration-proof strength OFF means 2 (119) outputs t ₈ hours (t ₈ <t ₄ ) from the ON input of the switch SW2 of the release means 17. Then, this output is input to the narrowing means 127 and the flashing means 128.

The above-mentioned t ₈ time is set to, for example, 1 second, and when the exposure time is longer than 1 second, the exposure means 11
From 6 to the flashing means 128 and the narrowing-down means 127, the in-exposure information and the trailing edge information of the vibration-proof strength off means 2 are used to narrow down the flash and emit the strobe light.

Here, the reason why the strobe light is emitted is to compensate for insufficient exposure due to narrowing down.

It is difficult to maintain the vibration isolation precision with high precision for a long time (for example, 1 second) (to the extent that the blur is not noticeable in the photograph).
This is because the output stability of the shake detection sensor and the limit of the sensor output calculation circuit. Therefore, in the case of t ₈ hours or more, the aperture is narrowed down to prevent the camera shake from being captured.

The drive coil control means 120 has a switch S.
T ₅ hours from the ON input of W1 (t ₅ ≧ t ₄ : for example, 15
Second), and this falling output is input to the drive coil disconnecting means 130, and the switch piece 130a connected to the terminal 130b is connected to the terminal 130c to drive the shorted coil. Connect to means 15,
The driving of the correction optical means 16 is started. That is, the drive coil control means 120 has a role of driving the correction optical means 16 after the switch SW1 is turned on.

The signal of the switch SW1 of the release means 17 is input to the image stabilization off command means 121, and the output continues for t ₆ hours (for example, 4 seconds) after the switch SW1 is turned off. Then, this output is input to one end of the AND gate 122a of the target value input stop means 122. A position detection signal of the correction optical means 16 is input to the drive range detection means 129, and this signal is output when it is within a certain range (that is, within a certain drive range), and this signal is output by the target value input stop means 1.
22 is input to the other end of the AND gate 122a.

The above "fixed range" of the drive range detecting means 129 is variable by the input zoom information output means 111 and focus information output means 110 signals, and when the zoom is wide or close to the focus. , Expand this range.

Then, the target value input stopping means 122 is provided with the signal from the image stabilization off command means 121 and the drive range detecting means 12.
It outputs only when there are both outputs of 9 and inputs the signal to the anti-vibration strength OFF means 1 (118) and the timer 3 (126). This input resets the image stabilization strong off means 1 (118), but since the switch SW1 has already been turned off at this time, the image stabilization strong off means 1 (118) does not output. That is, the output of the target value input stopping means 122 causes the vibration proof strength OFF means 1 (118) to stop the output, the sample hold circuit 12a returns to the sample state, and the target value becomes zero. Therefore, the correction optical means 16 returns to the zero point,
As described above, the correction optical means 16 is locked and the coil is short-circuited.

The "control operation for stopping the image stabilization" in the first embodiment of the present invention having the above-mentioned structure will be described.

FIG. 2 shows the driving position of the correction optical means 16. For example, when the zoom is tele, the image stabilization continues even after the switch SW1 is turned off, and both the image stabilization off command means 121 and the drive range detection means 12a are shown. Is output (reference numeral 133 in FIG. 2)
At the time point (), the correction optical means 16 is returned to the zero point and locked.

When the zoom is wide, the output of the signal of the drive range detecting means 129 is quick (the range is widened from the tele 131 to the wide 132), so that the correcting optical means 16 returns to the zero point early as indicated by reference numeral 134. To be done. Here, since the range is widened when the wide angle is set, a sharp framing change is performed when the correction optical unit 16 is returned to the zero point, which seems to make the photographer feel uncomfortable. Since the amount of eccentricity of the optical axis due to the driving amount of the correction optical means is small, no discomfort is felt.

Next, the exposure control by the image stabilization strength off means 2 (119) will be described.

FIG. 3 shows an example in which vibration is applied in a sinusoidal manner for image stabilization during exposure.

FIGS. 3B and 3C are shakes actually applied to the camera, and the sine wave shake is slightly weighted by the low-frequency shake to the right. However, since the vibration detection means 11 cannot detect low-frequency shake, the drive position of the correction optical means 16 performs a sinusoidal drive without low frequency, as shown in FIG. Therefore, the remaining correction on the actual image plane is as shown in FIG.
As shown in (d) and (e), the shake of δ ₁ is usually reflected.

However, as explained in FIG. 1, by narrowing down after t ₈ hours, the shake of δ ₁ is not reflected, and
It is reduced to the unsettled amount δ ₂ until t ₈ hours. Then, the strobe is made to emit light in order to make up for the underexposure, but since the light emission time is extremely short, the amount of remaining shake during this period is extremely small and there is no reflection.

(Second Embodiment) FIG. 4 is a block diagram showing the schematic arrangement of an image stabilization camera according to the second embodiment of the present invention.

The difference from FIG. 1 is that the ratio change control means 21
Is added. It should be noted that in FIG. 4, the vibration damping strength OFF means 2 (119), the narrowing means 127 and the flashing means 128 of FIG. 1 are omitted for the sake of simplicity.

The purpose of this second embodiment is to switch SW1.
After turning off (after the output of the image stabilization off command means 121), the correction optical means 16 is returned to a certain range at an early stage and locked to further save power.

The ratio change control means 21 has a function of inputting the signal of the image stabilization off command means 121 and gradually decreasing the amplification factor of the image stabilization sensitivity change means 46.

The ratio change control means 21 is reset by turning on the switch SW1 of the release means 17.

In the above construction, when the switch SW1 is turned off and the image stabilization off command means 121 outputs, the ratio change control means 21 gradually reduces the amplification factor of the image stabilization sensitivity change means 46. In other words, the effectiveness of anti-vibration is gradually deteriorated. Then, the movement amount of the correction optical unit 16 gradually decreases.

FIG. 5A shows the driving position of the correction optical means 16 when the zoom is telescopic, and the correction optical means 16 when the ratio change control means 21 shown by the broken line is not used since the switch SW1 is turned off. The drive amount of the solid line becomes smaller than the drive amount of No. 1, and when the drive amount enters the constant drive range 131, the target value of the image stabilization switching unit 12 is set to zero and the correction optical unit 16 is set as in FIG. Locks back to the zero position and shorts the coil.

Therefore, the constant drive range 131 in the case of the broken line
The time can be shortened by τ compared to the timing of entering. When the zoom is wide, the constant drive range 132 widens, so that it is possible to stop the image stabilization earlier, as shown in FIG.

(Third Embodiment) FIG. 6 is a block diagram showing the schematic arrangement of an image stabilizing camera according to the third embodiment of the present invention.

In this embodiment, sensor output arithmetic circuit control means 22 is provided instead of the ratio change control means 21 of FIG. 4 in the second embodiment.

The sensor output arithmetic circuit control means 22 inputs the signal of the image stabilization off instruction means 121 and receives the vibration detection means 11 as a signal.
Change the frequency characteristics of the sensor output calculation circuit. For example, the attenuation of the low frequency side of the output of the vibration detection means 11 is gradually increased from the output of the image stabilization off command means 121 (a frequency of 0.1 Hz or less was attenuated gradually to 0.5 Hz, Widen the frequency band to be attenuated at 1 Hz.)

The vibration displacement due to camera shake is large on the low frequency side and becomes smaller on the high frequency side. Therefore, the sensor output calculation circuit 22 is designed to increase the attenuation on the low frequency side.
As is the case with FIG. 4, the target value on the low frequency side where the driving amount of the correction optical means 16 is large becomes smaller as is changed.
This is explained in detail.

FIG. 7A shows the structure of the vibration detecting means 11. The vibration detecting means 11 calculates a shake detecting sensor (angular velocimeter such as a vibration gyro) 11a which outputs an angular velocity ω and calculates this output (low speed). It is composed of a high-pass filter that attenuates the frequency and a sensor output calculation circuit 11b that integrates the angular velocity and converts it into an angle θ.

When the sensor output arithmetic circuit 11b is, for example, an analog circuit, as shown in FIG.
3, the variable resistor 24 and the operational amplifier 25 constitute a high pass filter, and the capacitor 27, the resistor 26 and the operational amplifier constitute an integrator.

The frequency characteristic of the circuit is shown in FIG.
As shown in (a), the low frequency is attenuated at 0.1 Hz (solid line 29) and the high frequency is integrated (solid line 210) (attenuating the high frequency at a constant ratio is equivalent to integration). Has become.

Here, the sensor output arithmetic circuit control means 22
Changes the resistance value of the variable resistor 24 and decreases the resistance value (reduces the time constant).
The characteristic of (a) is 0.5 H as shown by broken lines 211 and 212.
The characteristic is changed to attenuate the angular velocity output of z to 1 Hz or less.

FIG. 8B shows the output of the sensor output calculation circuit 11b before the frequency characteristic is changed, and shows the low-frequency large shake 213.
The high-frequency small shake 214 is heavy on a and forms a shake output 215a.

Here, the sensor output arithmetic circuit control means 22
When the low-frequency large shake is attenuated by, the amplitude of the shake output 215a becomes smaller as shown in FIG. 8C. Therefore, the correction optical means 16 enters the constant drive range at an early stage, and the same effect as in FIGS. 5A and 5B can be obtained.

(Fourth Embodiment) FIG. 9 is a block diagram showing the schematic arrangement of an image stabilization camera according to the fourth embodiment of the present invention.

In this embodiment, instead of the sensor output arithmetic circuit control means 22 in FIG. 6, the present position holding means 31, the centripetal force input means 32, the buffer means 33, the reversing means 3 are provided.
4 is equipped.

The current position holding means 31 holds and stores the current position of the correction optical means 16 in the sample hold circuit 31a in response to the signal input from the image stabilization off instruction means 121. The centripetal force input means 32 is normally a switch piece 32a.
Is connected to the terminal 32c (GND, etc.), but the switch piece 32a is activated by the signal input of the image stabilization off command means 121.
Is connected to the terminal 32b to hold the correction optical means 1
The current position of 6 is input to the buffer means 33.

The buffer means 33 is a low pass filter composed of a well-known RC (resistor and capacitor), and gradually increases the output from zero to the current position by inputting the current position. This signal is input to the inverting means 34, and its output gradually decreases from zero to the minus current position.
This output is input to the driving means 15 in addition to the target value from the ratio changing means 47.

Now, as shown in FIG. 10A, the switch S
The current position of the correction optical means 16 when W1 is off is "-d".
At this time, the output of the reversing means 34 gradually changes from zero to "d", so that the correction optical means 16 moves from the current position [-d] to the zero position while continuing the image stabilization (the broken line is described above. Of the current position holding means 31, the centripetal force input means 32, the buffer means 33, and the reversing means 34). Then, when the correction optical means 16 enters the fixed drive range, the correction optical means 16 is returned to zero, locked, and the coil is short-circuited.

With the above-mentioned structure, the image stabilization is completed earlier by τ ′ than in the case of the broken line.

As shown in FIG. 10B, the switch SW1
Even when the current position "-d '" when is off is larger than that in the case of FIG. 10A, the correction optical means 16 is returned with a large centripetal force, so that the image stabilization can be completed early.

(Fifth Embodiment) In the above first to fourth embodiments (FIGS. 1 to 10), the image stabilization is performed when the correction optical means 16 enters the constant drive range after the switch SW1 is turned off. Although the correction optical means 16 is stopped and locked, the correction optical means 16 may be locked by stopping the image stabilization a predetermined time after the switch SW1 is turned off.

FIG. 11 is a block diagram showing the schematic arrangement of the image stabilizing camera according to the fifth embodiment of the present invention.

The difference from FIG. 1 is that the drive range detecting means 12
Instead of 9, the timer 4 (48) is provided, and the AND gate 122a of the target value input stopping means 122 is the OR gate 122.
It is changed to b.

The timer 4 (48) inputs the signals of the zoom information output means 111 and the focus information output means 110 to make the count time t ₇ variable, and, for example, when the zoom is wide or the focus is close, the count time is changed. shorten.

The timer 4 starts counting when receiving the OFF signal of the switch SW1 of the release means 17, and outputs after 2 seconds when the focus is infinite in the zoom tele.
This output is input to one end of the OR gate of the target value input stop means 122, the target value input stop means 122 is output, and the target value of the image stabilization switching means 12 is set to zero.
Is returned to the zero position and locked, and the coil is short-circuited as in FIG.

The target value input stopping means 122 is the OR gate 1.
22b indicates that even if the switch SW1 is not turned off, a certain time t ₄ (t ₄
This is because after ′ + t ₄ ) the image stabilization strength OFF output means 123 stops the image stabilization and the correction optical means 16 is locked.

In FIG. 12, it can be seen that the correction optical means 16 is reset to zero and locked after t ₇ (variable for tele, wide and focus) after the switch SW1 is turned off.

The photographer rarely looks into the finder for a while after the switch SW1 is turned off, and if the count t _{7 of the} timer 4 is set longer than the time (for example, 3 seconds) during which the finder is kept looking, the photographer Does not give discomfort to framing changes.

Another difference between FIG. 11 and FIG. 1 is that
Instead of the flash means 128 and the narrowing means 127, the shutter of the exposure means 116 is controlled by the output of the vibration proof strength OFF means 2 (119).

That is, when the exposure is longer than the time t ₈ when the image stabilization precision is maintained, the shutter is closed to prevent the image deterioration due to the shake.

Similar to FIG. 3, FIG. 13 is a diagram showing image deterioration due to shake, but in FIG. 13 (e), when image deterioration due to shake is predicted after t ₈ hours, the shutter is closed and exposure is performed. It is configured to stop. Needless to say, the underexposure may be corrected by emitting a strobe light immediately before closing the shutter.

(Sixth Embodiment) FIG. 14 is a block diagram showing the schematic arrangement of an anti-vibration camera according to the sixth embodiment of the present invention.

The difference from FIG. 4 is that the drive range detecting means 12
Instead of 9, the timer 4 (48) is provided and the target value input stopping means 122 is changed to an OR gate 122b.

As described with reference to FIG. 4, the image stabilization sensitivity changing means 4
The amplification degree of the target value output of 6 gradually decreases after the switch SW1 is turned off. Therefore, the fact that the correction optical means 16 is within the constant drive range can be substituted by the count time after the switch SW1 is turned off.

Therefore, in FIG. 14, counting may be started after the switch SW1 is turned off, and output after t ₇ (for example, 1 second) to stop image stabilization and lock the correction optical means 16.

The count time t ₇ of the timer 4 is variable even in the zoom and focus states so that the zoom is wide.
Alternatively, when the focus is near, the count time t ₇ is shortened. This is the correction optical means 1 when the focal length is short.
Even if the amount of return to zero of 6 is large, the photographer is not concerned, so the count time is short, and the image stabilization sensitivity changing means 4
In a state where the amplification degree of 6 is not so small, the correction optical means 1
This is because 6 may be returned to zero.

In FIGS. 15A and 15B, the zoom is telephoto,
When the zoom is set to the tele position, which is the driving position of the correction optical unit 16 at the wide angle, t ₇ hours after the switch SW1 is turned off,
Correcting optical means 16 stops vibration isolation when it came to near zero, but for a wide, shorter t ₇ hours from off the switch SW1, to stop the anti-vibration while still correcting optical unit 16 is not in the vicinity of zero ing. By doing this, it is possible to stop the vibration isolation early.

(Seventh Embodiment) FIG. 16 is a block diagram showing the schematic arrangement of an anti-vibration camera according to the seventh embodiment of the present invention.

The difference from FIG. 6 is that the drive range detecting means 12
Instead of 9, a timer 4 (48) is provided.

This is an example in which FIG. 6 is changed to FIG. 16 similarly to the case where FIG. 4 is changed to FIG. 6, and the time constant of the sensor output arithmetic circuit by the sensor output arithmetic circuit control means 22 is set to “large”. Timer 4 (4
The time t _{7 of} 8) is set.

Even with such a configuration, as shown in FIGS.
The same effect as is produced.

(Eighth Embodiment) FIG. 17 is a block diagram showing the schematic arrangement of an image stabilization camera according to the eighth embodiment of the present invention.

This is an example in which FIG. 9 is changed to FIG. 17 similarly to the case where FIG. 4 is changed to FIG.
Corresponding to the time when the correction optical means 16 gradually returns to the zero position while the image stabilization is continued from 1 being off, the timer 4
The time t ₇ of (48) is set.

Even with such a configuration, as shown in FIG.
As shown in (b), since the correction optical means 16 is located near the zero position after a lapse of a certain time (t ₇ ) after the switch SW1 is turned off, the framing change when the image stabilization is stopped is small, and the photographing is performed. Does not cause discomfort to persons.

According to each of the above embodiments, the switch SW1
The image stabilization is continued even after the switch is turned off, and the image stabilization is stopped during the image stabilization when the correction optical means 16 enters a certain range or after a certain period of time passes. It was a vibration-proof system with a good feel that did not cause screen fluctuations after turning off.

Further, by making the above-mentioned fixed range or fixed period variable according to the focal length of the lens, it becomes possible to stop the image stabilization at an early stage.

Further, by re-controlling the exposure means 116 such as stroboscopic light emission, narrowing down, shutter closing, etc. when the deterioration of the image stabilization accuracy is predicted, the image deterioration due to the shake can be reduced.
