Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an anti-vibration camera which detects low-frequency vibration generated in a camera and corrects an image blur.

[0002]

2. Description of the Related Art In the current camera, all the important operations for photographing such as exposure determination and focusing are automated, so that even a person unskilled in the operation of the camera has a very low possibility of photographing failure.

Further, recently, a line-of-sight input focus adjusting means for focusing on a place (subject) on which the photographer gazes in the viewfinder has been developed, and a system for preventing camera shake applied to the camera has been studied. The factors that cause shooting mistakes are almost gone.

Here, a system for preventing camera shake will be briefly described.

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, it is possible to take a photograph without image shake even if such a camera shake occurs. 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 achieve the ability to take a picture without causing 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. Will be needed.

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 mechanism that decenters the photographing optical axis is driven to suppress the image blur.

An outline of a vibration isolation system using the vibration detection means will be described with reference to FIG.

When input to y, the support frame 72 is driven and the outputs of the position detection elements 78p and 78y change. Coil here 79
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.
2 is stable. The adder circuits 731p and 731y are circuits that add the output from the position detection elements 78p and 78y and the command signals 730p and 730y from the outside, and the compensating circuits 728p and 728y are circuits that further stabilize the control system. Circuits 729p and 729y are coils 79p and 79

FIG. 22 is a circuit diagram showing details of the drive control system of the correction means shown in FIG. 21. Here, only the pitch direction 725p will be described (yaw direction 726y.
Is also the same).

Current-voltage conversion amplifiers 732pa and 732

The output of the adder circuit 731p is the compensation circuit 7
It is input to the drive amplifier 735p via 28p, the drive signal of the pitch coil 79p is generated here, and the correction means is displaced. The drive amplifier 735p, the resistor 737p, and the transistors 736pc and 736pc form a drive circuit 729p in FIG.

The addition amplifier 741pa obtains the sum of the outputs of the current-voltage conversion amplifiers 732pa and 732pb (total amount of light received by the position detection element 78p), and the drive amplifier 742pb receiving this signal drives the light projecting element 76p accordingly. . Above, the addition amplifier 732a, the drive amplifier 742

The light projecting element 76p is extremely unstable in temperature and the like, and its projecting amount changes, and accordingly the differential amplifier 73p.
Although the position sensitivity of 3p changes, if the light projecting element 76p is controlled by the drive circuit so that the total amount of received light is constant as described above, the change in position sensitivity is reduced.

Here, the support frame 7 shown in FIG. 20 and FIG.
The locking means for locking 2 will be described.

The mechanical lock chassis 7 described with reference to FIG.
18, the plunger 719, the spring 720, the mechanical lock arm 721, and the shaft screw 722 constitute a locking means, and the locking means is viewed from the direction of arrow 718a in FIG.
23 (a), and a sectional view of the plunger 719 is shown in FIG. 23 (b).

In FIG. 23B, the plunger 719
Is a slider 719a, a stator 719b, a coil 719c provided on the stator 719b, and a permanent magnet 71.
It is composed of 9d. Then, as shown in FIG. 23A, the slider 719a is hooked in a hole 721b of a mechanical lock arm 721 rotatably supported by a shaft 722, and the mechanical lock arm 721 is rotated by a spring 720 in the direction of an arrow 720a. It is energized. Therefore, the force F with which the slider 719a is pulled out from the stator 719b is
Always receive out. However, since the slider 719a is in contact with the permanent magnet 719d, its attractive force is large and is not moved by the force of the spring 720 (Fmg> Fou).
t: Fmg is the attractive force of the permanent magnet). In this state, the projection 721a at the tip of the mechanical lock arm 721 is fitted in the hole 72d of the support frame 72, and the support frame 72 is locked.

Next, when a current is applied to the coil 719c in a desired direction, the flow of magnetic flux in the magnetic circuit formed by the permanent magnet 719d, the slider 719a and the stator 719b changes, and the slider 719a and the permanent magnet 719d are attracted. The power weakens. Then, the mechanical lock arm 7 is driven by the force of the spring 720.
21 rotates in the direction of arrow 720a, the protrusion 721a is separated from the hole 72d of the support frame 72, and the locking is released (Fout.
> Fmg-Fi Fi is current repulsive force). At this time, the slider 719a is also pulled out of the stator 719b at the same time, and a gap δ is generated between the slider 719a and the permanent magnet 719d.

As is well known, since the attraction force is inversely proportional to the square of the distance between the permanent magnet 719d and the opposing object, the attraction force becomes extremely small due to the gap δ. Therefore, the coil 71
Even if the power supply to 9c is cut off, the support frame 72 is pressed by the urging force of the spring 720.
The unlocked state of can be maintained.

Next, when a current is applied to the coil 719c in the opposite direction, the resultant force of the absorption force of the slider 719a and the attraction force of the permanent magnet 719d by this current becomes larger than the force of the spring 720, and the slider 719a moves into the stator 719b. Pulled in (Fmg + Fi> Fout) Once, slider 719
When a starts to be drawn into the stator 719b, the absorption force of the permanent magnet 719d is increased due to the decrease in the gap δ, and the slider 719a moves to the permanent magnet 7a.
While contacting 19d, the projection 721a enters into the hole 72d of the support frame 72 and locks the support frame 72 again.

As described above, a current is passed through the plunger 719 only at the time of locking and unlocking, so that a bistable structure for holding each state is realized, and a compact and power-saving locking means is realized. ing.

FIG. 24 is a block diagram showing the outline of the image stabilization system.

In FIG. 24, reference numeral 91 denotes the vibration detecting means 83p and 83y shown in FIG. 19, which is a shake detection sensor for detecting the angular velocity of a vibration gyro and a DC output of the shake detection sensor.
It is composed of sensor output calculation means for obtaining the angular displacement by integrating after cutting the component.

The angular displacement signal from the vibration detecting means 91 is input to the target value setting means 92. This target value setting means 9
2 is a variable differential amplifier 92a and a sample hold circuit 9
2b, and a sample hold circuit 92b
Is always being sampled, the two signals inputted to the variable differential amplifier 92a are always equal and the output thereof is zero. However, when the sample-hold circuit 92b is brought into the hold state by the output from the delay means 93 which will be described later, the variable differential amplifier 92a sets the time to zero and starts outputting continuously.

The amplification factor of the variable differential amplifier 92a is variable by the output of the image stabilization sensitivity setting means 94. The reason is that the target value signal of the target value setting means 92 is a target value (command signal) that causes the correction means to follow, but the correction amount (anti-vibration sensitivity) of the image plane with respect to the drive amount of the correction means is
This is because it changes depending on the optical characteristics based on the change in focus such as focus, and thus compensates for the change in the image stabilization sensitivity. Therefore, the image stabilization sensitivity setting unit 94 receives the zoom focal length information from the zoom information output unit 95 and the focus focal length information based on the distance measurement information of the exposure preparation unit 96, and sets the image stabilization sensitivity based on the information. The target value setting means 9 extracts the image stabilization sensitivity information preset based on the calculation or the information.
The gain of the variable differential amplifier 92a of No. 2 is changed.

The correction drive means 97 is the drive control circuit shown in FIG. 22, and the target values from the target value setting means 92 are input as command signals 730p and 730y.

The correction starting means 98 is the driving circuit 7 of FIG.
29p, 729y and the coils 79p, 79y are connected to each other.
By connecting it to 8c, both ends of each of the coils 79p and 79y are short-circuited, and when the signal of the logical product means 99 is input, the switch 98a is connected to the terminal 98b and the correction means 910 is in the control state (still Although shake correction is not performed, power is supplied to the coils 79p and 79y, and the position detection elements 78p and
The correction means 910 is stabilized at the position where the 78y signal becomes substantially zero). At the same time, the output signal of the logical product means 99 is also input to the locking means 914, whereby the locking means unlocks the correction means 910.

The correcting means 910 is the position detecting element 7
Input the position signals of 8p and 78y to the correction driving means 97,
Position control is performed as described above.

The logical product means 99, when both the release half-press SW1 signal of the release means 911 and the output signal of the image stabilization switching means 912 are input, the AND gate 99a, which is a component thereof, outputs the signal.

That is, when the photographer operates the anti-vibration switch of the anti-vibration switching means 912 and the release means 911 presses the release half-way, the correction means 910 is unlocked and enters the control state.

The SW1 signal of the release means 911 is input to the exposure preparation means 96 to perform photometry, distance measurement, and lens focusing drive, and as described above, output focus focal length information to the image stabilization sensitivity setting means 94. .

The delay means 93 receives the output signal of the logical product means 99, outputs it after one second, for example, and causes the target value setting means 92 to output the target value signal as described above.

Although not shown, the vibration detecting means 91 also starts to operate in synchronization with the SW1 signal of the release means 911. As described above, the sensor output calculation including a large time constant circuit such as an integrator requires a certain amount of time from the start to the stable output.

The delay means 93 plays a role of outputting a target value signal to the correction means 910 after waiting until the output of the vibration detection means 91 stabilizes, and prevents vibration after the output of the vibration detection means 91 stabilizes. It is configured to start.

The exposure means 913 performs the mirror-up by the release push-off SW2 signal input of the release means 911, opens and closes the shutter at the shutter speed obtained based on the photometric value of the exposure preparation means 96 to perform the exposure, and the mirror-down. Then, the shooting ends.

After the photographing, the photographer releases the shutter 911.
When the hand is released and the SW1 signal is turned off, the logical product means 99 stops the output, the sample hold circuit 92b of the target value setting means 92 enters the sampling state, and the output of the variable differential amplifier 92a becomes zero. Therefore, the correction means 91
0 returns to the control state in which the correction drive is stopped.

Since the output of the logical product means 99 is turned off, the locking means 914 locks the correction means 910, and then the switch 98a of the correction starting means 98 is connected to the terminal 98c, and the correction means 910 becomes Get out of control.

The vibration detecting means 91 continues to operate for a fixed time (for example, 5 seconds) after the operation of the release means 911 is stopped by a timer (not shown), and then stops.
This is because it is complicated for the photographer to continuously perform the release operation after stopping the release operation. Therefore, it is possible to prevent the vibration detection means 91 from being activated each time at such a time, and to shorten the waiting time until the output is stabilized. Vibration detection means 9
When 1 is already activated, the vibration detecting means 91 sends an activated signal to the delay means 93 to shorten the delay time.

[0057]

In the image stabilization system described above, image stabilization is started when the SW1 signal is output from the release means 911. In this way, the image stabilization is started by the half-pressing operation of the release means 911 for the preparatory operations such as the photometry and the distance measurement of the camera (the structure also serving as the switch). It does not require any special operation for the purpose, and the handling of anti-vibration operation is extremely simple.

However, in actuality, there is a case where the image stabilization is not required when the SW1 signal is generated, that is, at the time of preparation for photographing, and the image stabilization may be performed only during the exposure. For example, when performing anti-vibration while following a moving subject, such as during sports photography, frequent camera work is required, but the anti-vibration function also works when changing pan and framing at that time. There is also a problem in that it is impossible to instantaneously determine a composition.

On the other hand, if the operation member for image stabilization is a switch different from the release switch, the operation becomes complicated, and even if the image stabilization is attempted only during exposure, the photographer operates the image stabilization switch in synchronization with the start of exposure. It was extremely difficult to do.

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 main structure of an image stabilizing camera according to the first embodiment of the present invention. The same parts as those in FIG. 24 are designated by the same reference numerals.

First, release release (SW2 signal generation)
The "real-time exposure mode" in which the release time lag from exposure to exposure is shortened will be described.

In FIG. 1, the mode switching means 11 is for selecting "normal exposure mode" or "real-time exposure mode". When the "real-time exposure mode" is selected by the photographer, The switch pieces 12a, 12d of the mode control means 12 are connected to the contacts 12e, 12h,
The switch pieces 12b and 12c are disconnected from the contacts 12f and 12g. In the "normal exposure mode", the switch piece 12
The a and 12d are disconnected from the contacts 12e and 12h, and the switch pieces 12b and 12c are connected to the contacts 12f and 12g.

After that, when the SW1 signal is generated in the release means 911, the exposure preparation means 96 performs photometry, distance measurement, and lens focusing drive, and the exposure preparation completion signal from the exposure preparation means 96 is the contact point of the mode control means 12. It is input to the aperture control means 13 via 12e and the switch piece 12a. The aperture control means 13 responds to this input by the exposure preparation means 96.
The diaphragm is driven based on the photometric value from. When the SW2 signal is generated in the release means 911, the signal is input to the exposure means 913-1 via the contact 12h of the mode control means 12 and the switch piece 12d, so that the exposure means 913-1 prepares for exposure. Exposure is performed by opening and closing the shutter based on the photometric value from the means 96.

In the "normal exposure mode", the SW1 signal generated in the release means 911 is similarly the exposure preparation means 96.
However, at this time, even if an exposure preparation completion signal is sent from the exposure preparation means 96 to the mode control means 12, the connection between the switch piece 12a and the contact 12e is cut off, so the aperture control means 13 It is not input to, and diaphragm drive is not performed. After that, when the SW2 signal is generated in the release means 911, the signal is the contact 12 of the mode control means 12.
f, it is input to the aperture control means 13 via the switch piece 12b, the aperture is driven based on the photometric information from the exposure preparation means 96, and the drive completion signal is output to the release time lag adjusting means 14 after the aperture drive is completed. It

The release time lag adjusting means 14 receives the drive completion signal as it is from the mode control means 12 as it is.
However, in the later-described "second mode (mode for starting image stabilization by generating SW2 signal)", the drive completion signal of the aperture control means 13 is delayed and sent to the mode control means 12.
The signal from the release time lag adjusting means 14 is input to the exposure means 913-1 via the contact 12g of the mode control means 12 and the switch piece 12c, and the shutter is opened / closed based on the photometric information from the exposure preparation means 96 to perform the exposure. To do. That is, in the "second mode", the release time lag from generation of SW2 to exposure is lengthened by the delay time of the release time adjusting means 14 (for example, 0.3 seconds) (the image stabilizing operation stabilizes as will be described later). To wait for).

The exposure mode display means 15 is for displaying the "normal exposure mode" or the "real-time exposure mode" to the photographer.

As described above, in the "normal exposure mode", the SW
While the diaphragm drive is performed after the two signals are generated, in the "real-time exposure mode", the release time lag can be shortened as much as the diaphragm drive is completed before the SW2 signal is generated.

In the TTL camera, of course, in the "real-time exposure mode", the finder image becomes dark when the photographer is looking because the aperture is driven by the generation of the SW1 signal, but the release time lag is short. On the other hand, in the "normal exposure mode", there is an advantage that the finder image does not become dark due to the generation of the SW1 signal, and the photographer appropriately selects the mode switching means 11
You can operate the to shoot your favorite photos.

FIG. 2 shows a timing chart of each functional operation in the “normal exposure mode” and the “real-time exposure mode”. As is clear from FIG. 2, the “release time lag 1” in the “normal exposure mode” is shown. On the other hand, the "release time lag 2" in the "real-time exposure mode" is shortened by the difference in aperture driving timing.

Returning to FIG. 1, the image stabilization start selecting means 16 is
This is for the photographer to select either "first mode" in which image stabilization is performed by the SW1 signal from the release means 911 or "second mode" in which image stabilization is performed by generating the SW2 signal. When the first mode is selected by the activation selecting means 16, the switch piece 16a is connected to the contact 16b. Therefore, when the SW1 signal is generated in the release means 911, the signal is input to the vibration detecting means 91 via the contact 16b and the switch piece 16a to activate the vibration detecting means 91, and as in the conventional example, the logical product means. Is inputted to the locking means 914 via 99, and the locking of the correction means 910 is released,
Further, the sample hold circuit of the target value setting means 92 is held via the delay means 93 to start image stabilization.

In addition, the anti-vibration activation selecting means 16 causes the "second
When the "mode" is selected, the switch piece 16a is connected to the contact 16c, and the S generated in the release means 911 is generated.
When the W2 signal is generated, the signal is similarly input to the vibration detecting means 91 and the logical product means 99 via the contact 16c and the switch piece 16a, and the image stabilization is started by the generation of the SW2 signal.

The image stabilization mode display means 17 is responsive to the signal from the image stabilization start selection means 16 for the above-mentioned "first mode".
And which of the "second modes" has been selected by the photographer.

Here, the "first mode" is a mode in which the image stabilization is performed from the time when the SW1 signal is generated as in the conventional case.
The "second mode" is a mode in which the image stabilization is performed only during exposure (when the SW2 signal is generated), and it is inconvenient that the image stabilization is performed when the SW1 signal is generated for shooting that requires frequent framing and panning. When shaking is performed, framing and panning vibrations are also prevented, and framing panning cannot be performed.)

When the "second mode" is selected by the image stabilization start-up selection means 16, the second mode signal is input to the mode switching means 11, and the mode switching means 11 causes the "real-time exposure mode". When the selection is disabled and the "real-time exposure mode" is already selected by the mode switching means 11, the mode switching means 1 is selected.
The signal from No. 1 is input to the image stabilization start-up selection means 16, and the image stabilization start-up selection means 16 disables the "second mode" selection.

The RT (real time) warning means 18 is supplied with the output signal of the image stabilization start selection means 16 and the output signal of the mode switching means 11, respectively, and is in the "second mode".
In addition, when the "real-time exposure mode" is set, a warning is displayed to the photographer. (Of course, at this time, it automatically returns to the "first mode" or the "normal exposure mode" as described above.) Here, the "second mode" and the "real-time exposure mode" are compatible with each other. Explain the reason for not allowing it.

In FIG. 3, in the "second mode",
The correction means starts driving at a certain time A (timing slightly delayed from the generation of the SW2 signal) before exposure with respect to the actual shake to cancel the shake, but the drive of the corrector starts. Insufficient response remains in the rising section of
There is a deviation from the ideal drive waveform shown by the dotted line in (b). Since this gap is short, in the "normal exposure mode" it is almost settled within the "release time lag 1" time and sufficient image stabilization can be performed during actual exposure, but in the "real time exposure mode" the "release time lag 2" Exposure is started before the correction means is stable because it is short,
There is a possibility that sufficient vibration isolation will not be possible.

Therefore, the "real-time exposure mode" and the "second mode" are not compatible with each other.

In the "normal exposure mode", the driving of the correction means is almost stable during the "release time lag 1", but strictly speaking, it is not sufficiently stable. Therefore, when the "second mode" is selected by the image stabilization start-up selecting means 16, the second mode signal is output to the release time lag adjusting means 14, and the "normal exposure mode" is set as described above. The release time lag is increased so that the driving of the correction means is sufficiently stable before the exposure is started.

FIG. 4 shows the "" first mode "" for image stabilization.
And "second mode", and "normal exposure mode" and "real-time exposure mode" for exposure, which are operation flow charts showing the operation, which will be described below.

When the image stabilization switching means 912 is turned on, the operation from step 1001 is started by the processing of the microcomputer (not shown).

In step 1001, it is judged which exposure mode is selected, and if "normal exposure mode" is selected.
If so, the process proceeds to step 1002, where the exposure mode is set to the "normal exposure mode". And step 10
03, this time the vibration-proof mode is judged, and if it is the "first mode", the routine proceeds to step 1004 and the "first mode" is selected.
Mode ”is set, and the process returns to step 1001.

On the other hand, if it is determined in step 1003 that the image stabilization mode is not the "first mode", the flow advances to step 1005 to set the "second mode". Then, in step 1006, the exposure mode is checked again,
If it is the "normal exposure mode", step 1007
Go to step 100 and set the "normal exposure mode" to step 100.
Return to 1. Further, if it is not the "normal exposure mode" in step 1006, that is, the "real-time exposure mode", it is problematic to make the mode compatible with the "second mode" as described above. Therefore, the process proceeds to step 1008, where the RT warning means 18 issues a warning ("real-time exposure mode" cannot be set).

If it is determined in step 1001 that the "normal exposure mode" is not set, step 10
In step 09, the exposure mode is set to the "real-time exposure mode". Then proceed to step 1010,
Determine whether the image stabilization mode is the "first mode",
If so, the process proceeds to step 1004, the "first mode" is set, and the process returns to step 1001.

On the other hand, in step 1010, if the image stabilization mode is not the "first mode", the process proceeds to step 1012, and like step 1008,
Since it is problematic to make the "first mode" and the "second mode" compatible with each other, the RT warning means 18 issues a warning ("second mode" cannot be set).

The above flow is always circulated while the image stabilization switching means 912 is on, and each mode is set.

Returning to FIG. 1 again, the stability determining means 19 includes a signal from the vibration detecting means 91, shutter speed information from the exposure preparing means 96, and a lens focal length (zoom) from the image stabilization sensitivity setting means 94. Focus, focal length) information has been input, and here the stability of image stabilization is judged. That is, even if the output of the vibration detecting means 91 is unstable (immediately after the vibration detecting means 91 is started or immediately after a large panning), if the shutter speed is short or the focal length is short and the influence of shake is small, the reverse Even if the output of the vibration detecting means 9 is almost stable, the shutter speed is slow,
Alternatively, it is determined that the focal length is long and the influence of shake is large. Then, the result (vibration stabilization stability information) is input to the vibration isolation propriety display means 20, where the vibration isolation stability information is displayed so that the photographer can be informed whether the vibration isolation was properly performed. There is.

The second mode signal of the image stabilization start selection means 16 is input to the image stabilization enable / disable display means 20, and the image stabilization enable / disable display means 20 is in the "second mode" (SW2 signal generation). The above information is displayed only in the mode to start image stabilization with. This is because, in the "first mode", the photographer can confirm the state of the image stabilization on the viewfinder when the SW1 signal is generated, and the display allows the photographer to re-take the photograph as necessary. Is.

According to the first embodiment described above, the following effects are obtained.

1) Change the image stabilization start (change from the SW1 signal generation to the image stabilization start or the SW2 signal generation to the image stabilization start)
Therefore, the photographer can arbitrarily change the image stabilization start depending on the shooting situation, and the operability (camera work) when there are many panning and framing operations is improved.

2) "Real-time exposure mode" and "second
The mode (the image stabilization mode in which the image stabilization is started from the generation of the SW2 signal) ”is not compatible, it is possible to prevent shooting while the image stabilization is unstable.

3) In the "second mode", since the release time lag is lengthened, it is possible to prevent photographing during unstable image stabilization.

4) "Real-time exposure mode" and "second
When the "mode" is selected, a warning to that effect is displayed (by the RT warning means 18), and the photographer recognizes it and pays attention to the photographing (at the time when the SW1 signal is generated). (You can know that it will be the image stabilization from, or that it will be in the "normal exposure mode", and perform camera work accordingly)
It is possible to eliminate the failure of shooting.

5) "Real-time exposure mode" and "second
When the "mode" is selected, the previously selected mode is prioritized, so that the photographer can arbitrarily select the "real-time exposure mode" or the "second mode".

6) Since the image stabilization mode display of the "first mode (image stabilization mode in which image stabilization is started from SW1 signal generation)" or "second mode" is performed (image stabilization mode display means) (17), the photographer eliminates the failure of mode selection.

7) In the "second mode", since it is displayed whether or not the image stabilization has been properly operated during image capturing (by the image stabilization enable / disable display means 20), the photographer can obtain the information. You can redo the shooting based on.

(Second Embodiment) FIG. 5 is a block diagram showing the main structure of an image stabilizing camera according to the second embodiment of the present invention. The same parts as those in FIG. Details are omitted.

FIG. 5 differs from FIG. 1 (first embodiment) in the following points.

<< First Difference from First Embodiment >> The AND signal means 21 including the AND gate 21a outputs the output signal of the image stabilization switching means 912 and the output of the release means 911 (SW).
1) Since signals are input, a high level signal is input from the logic means 21 to the vibration detection means 91, the correction activation means 98 and the locking means 914 when both signals are generated.

Therefore, at this time, the vibration detecting means 91 is activated, the locking means 914 unlocks the correction means 910, and the correction activation means 98 drives the correction means 910 in the drive control state (as described in the conventional example). Electromagnetically stabilizes to the neutral position.The target value signal is not generated because the sample hold circuit of the target value setting means 92 is still in the sampling state,
Vibration isolation is not done). That is, the image stabilization switching means 91
Release means 9 by turning on 2 (anti-vibration main switch)
When 11 is pressed halfway, regardless of the above-mentioned “first mode” and “second mode”, the correction means 910 is brought into the ready state for activation, and the time from the start of the image stabilization until the driving of the correction means 910 is stable. The vibration detection means 91 is already in a stable state while being shortened.

Therefore, even in the mode such as the "second mode" in which the time lag between the image stabilization and the exposure is short, the time until the stabilization of the image stabilization becomes faster, and the release time lag adjusting means 1
The delay time of 4 can be shortened, which is convenient for shooting.

<< Second Difference from First Embodiment >> An image stabilization stop means 22 is newly provided, and the output of the image stabilization start selection means 16 is logically output via the image stabilization stop means 22. It has been input to the product means 99. The switch piece 22a of the image stabilization stop means 22 can be controlled only when the second mode signal of the image stabilization start selection means 16 is output.
2a is connected to the contact 22b (always in the "first mode"). In the "second mode", the image stabilization determination unit 23 (shutter speed information from the exposure preparation unit 96, zoom focal length information from the zoom information output unit 95, and shake information from the vibration detection unit 91 are input, and based on them. The switch piece 22a and the contact point 22b are turned on and off based on the output of (a means for determining whether or not vibration isolation is required). That is, when the image stabilization determination unit 23 determines that the image stabilization is not necessary, the switch piece 22a is disconnected from the contact 22b, and the S of the release unit 911 in the "second mode" is pressed.
Even if the W2 signal is generated and the signal reaches the image stabilization stop means 22 via the image stabilization start selection means 16, the logical product means 99
The image stabilization is not performed because it is not input to.

Here, when it is determined that the image stabilization is not necessary, the image stabilization is not performed, so that there is an advantage that the power is saved.

The image stabilization / non-activation display means 24 displays to the photographer that no image stabilization is to be performed, and prompts the photographer to carry out camera work in accordance therewith. In other words, let us know that by not performing image stabilization, it is also possible to take panning shots (when anti-vibration is performed, even panning shots are shaken and cannot be panned).

Now, the determination of whether or not the image stabilization is required by the image stabilization determination means 23 will be described with reference to the flowchart of FIG. 6 (a). This sequence is stored in the ROM in the microcomputer (not shown) of the camera.

This flow starts when the vibration detecting means 91 is started. First, in step 2001, the shutter speed Tv is input, and in next step 2002,
Enter the zoom focal length f. And next step 2
At 003, the product a of the shutter speed Tv and the zoom focal length f is calculated. In the following step 2004, it is determined whether or not the value of a is smaller than a ₀ .

In general, a photograph with no shake is 1 / focal length
Since it can be obtained by shooting at a shutter speed of (1 / f) or higher, the product a is "1" when the shutter speed is "1/300" and the zoom focal length is "300 mm". In this case, a ₀ Since it is the same as (= 1), there is no fear of shake, and when the shutter speed becomes “1/60”, “a =
5 "is larger than a ₀ , and there is a possibility of shake, and conversely, even at a shutter speed of" 1/60 ", the zoom focal length is" 60 mm ".
At the time of, “a = 1”, and there is no fear of shake.

Therefore, in step 2004, "a≤
In the case of "a ₀ ", there is no fear of shaking, so step 200
5, the image stabilization deactivating display means 24 is made to display that effect, and in the next step 2006, the connection between the switch piece 22a and the contact 22b in the image stabilization stop means 22 is cut off, and the processing returns to step 2001. .

On the other hand, when "a> a ₀ " in the above step 2004, the image stabilization is necessary, and at this time, it is determined whether or not the image stabilization system is stable. That is,
In step 2007, the shake amplitude θ of the vibration detecting means 91 is input, and in the next step 2008, it is determined whether the amplitude is equal to or less than the constant amplitude θ ₀ .

Here, FIG. 6B shows a shake amplitude waveform from the start of the vibration detecting means 91, which is equal to or larger than the amplitude θ ₂ until time t ₃ . Such a state occurs in an excessive state until the vibration detecting means 91 is stable, and accurate shake detection is not performed. Then, after t _3, the amplitude is within θ ₁ or less and is stable.

In step 2008, the shake amplitude is θ.
_When it is determined that the vibration is within ₀ or less and the correct image stabilization can be performed, the process proceeds to step 2009, the image stabilization enable display (by the image stabilization enable / disable display unit 20) is performed, and then the process returns to step 2001. When θ> θ ₀ in step 2008, the image stabilization display is not performed and the process immediately returns to step 2001.

The image stabilization determination means 23 is the image stabilization stop means 2.
Unlike 2, it works in the "first mode",
Even in this mode, the image stabilization display is displayed (the image stabilization stop is not performed).

According to the second embodiment described above, the following effects are obtained.

1) Even in the "second mode", the vibration detecting means 91 is activated in advance, and the locking of the correcting means 910 is released so as to be in the drive control state. Therefore, the response of the vibration isolation start becomes faster. , There is no need to lengthen the release time lag.

2) Since the correction means is electromagnetically and stably held at the neutral position of the correction stroke by the generation of the SW1 signal, it is possible to arbitrarily perform the correction drive in either direction according to the shake.

3) In the "second mode", when it can be determined that the image stabilization is not necessary, the image stabilization is not performed, so that the power is saved.

4) In the "second mode", when the image stabilization is not necessary, a message to that effect is displayed, so that the photographer can recognize it and perform the desired camera work, and widen the range of camera work. You can

5) Since the image stabilization display is provided, it is less likely that an image will be taken by mistake when image stabilization is not possible.

(Third Embodiment) FIG. 7 is a block diagram showing the main structure of an image stabilizing camera according to the third embodiment of the present invention. The same parts as those in FIG. The description is omitted.

FIG. 7 differs from FIG. 5 (second embodiment) in the following points.

<< First Difference from Second Embodiment >> The distance measurement information of the exposure preparation means 96 is also input to the image stabilization determination means 23, and the change in focal length due to distance measurement (focus) is prevented. Add to the material for making a judgment. Further, the vibration detecting means 91 inputs the shake angular velocity information instead of the shake amplitude.

With the above, more accurate image stabilization determination can be performed.

FIG. 8A is a flow chart showing the operation of the image stabilization judgment means 23, but it is basically the same as the flow chart of FIG. 6B.

First, in step 3001, the shutter speed Tv is input, and in the next step 3002, the zoom focal length f ₁ and the focal length variation due to focus are input. Then, in the next step 3003,
The shake angular velocity ω of the vibration detecting means 91 is input, and in the subsequent step 3004, the shutter speed Tv and the focal length f ₁
And the shake angular velocity ω are obtained.

In this case, the product a is the amount of shake actually recorded on the image plane. This is because the product of the shutter speed Tv and the shake angular velocity ω becomes the shake displacement during the exposure period, and this amount is proportional to the focal length f ₁ .

Therefore, in the next step 3005, this product a is compared with the allowable shake amount a ₀ ′.

In FIG. 6A, the product of the shutter speed Tv and the focal length f is used to judge the necessity of image stabilization, but in reality, even if the shutter speed is slow, if the shake is small, there is no need for image stabilization.
With this FIG. 8A, it is possible to more accurately determine the necessity of image stabilization.

In step 3005, "a≤a ₀
In case of '”, there is no fear of shaking, so step 3006
Then, in step S3007, the switch piece 22a in the image stabilization stop means 22 is disconnected from the contact 22b, and the process returns to step 3001.

On the other hand, when "a> a ₀ '" in the above step 3005, the process proceeds to step 3008 to input the shake amplitude θ of the vibration detecting means 91, and then the step 3
In 009, the product b of the shake amplitude θ and the product a obtained in the above step 3004 is obtained. This is determined in step 3005 that the image stabilization is necessary, and when the process proceeds to the next step 3008,
If the vibration isolation instability is not determined only by the vibration amplitude θ, but the vibration amount (product a) at that time is small and vibration of a small vibration amount is sufficient (b ≦ b ₀ ′), This is because it is determined in step 3010 that image stabilization is possible even if is slightly unstable. As a result, if the image stabilization is possible, the process proceeds to step 3011 and a message to that effect is displayed. As a result, it becomes possible to more accurately display whether or not the image stabilization is possible.

FIG. 8B shows the relationship between the shake angular velocity ω and time.

With the above flow, it becomes possible to more accurately determine whether or not the image stabilization is necessary and whether or not the image stabilization is possible.

<< Second Difference from Second Embodiment >> A time constant setting means 31 is newly provided, and the time constant setting means 31 receives the input from the image stabilization sensitivity setting means 94. From the zoom focal length information, the shutter speed information from the exposure preparation unit 96, and the focus focal length information obtained from the distance measurement,
It has a function of changing the time constant of the sensor output calculation means of the vibration detection means 91 so that the image stabilization characteristic suitable for correcting the shake expected on the image plane at that time is obtained.

FIG. 9 shows the above-mentioned vibration isolation characteristics.
This will be described with reference to the Bode diagram of (a).

The sensor output calculation means is composed of a high-pass filter for removing (DC cutting) the DC component (offset) superimposed on the shake angular velocity of the shake detection sensor, and an integrating circuit for integrating the shake angular velocity to make a shake displacement. Ordinarily, at the time of normal vibration isolation, as shown in Fig. 9 (a), 0.1 Hz
The lower component has characteristics of a high-pass filter that regards it as a DC offset component and attenuates it, and the component that has a component higher than 0.1 Hz as a shake angular velocity has an integrator characteristic of integration.
(DC cut band 2, integration band 2) When the shutter speed is fast and the focal length is short, the time constant setting means 31 DC cuts 1 Hz or more, for example, as shown in FIG. The above characteristics are integrated (DC cut band 1, integration band 1).

Specifically, as shown in FIG. 9B, the angular velocity ω of the shake detection sensor is input to the terminal a, and DC cut is performed by the high-pass filter 31 (composed of the resistor R1, the capacitor C1, and the operational amplifier). Then integrator 32 (resistor R
1, a capacitor C1, an operational amplifier, and a sensor output calculation means for integration, the resistances R1 and R1 'are reduced, the band in FIG. 9A moves from 0.1 Hz to 1 Hz.

Although FIG. 9B shows an example of an analog circuit, there are various variations of the high pass filter and the integrator in the analog circuit and the configuration other than that shown in FIG. 9B. Even when a digital high-pass filter and an integrator are digitally configured (the shake detection sensor output is A / D input to the microcomputer), the band can be similarly changed.

[0192] Changing the band in this way is called "changing the time constant", and decreasing the frequency band on the low frequency side from 0.1 Hz to 1 Hz means "decreasing the time constant". I will go. "

When the time constant is reduced as described above (for example, 1 Hz or less is DC cut and 1 Hz or more is integrated), there is an advantage that the time from the start of stabilization to stabilization can be shortened. Strictly speaking, in order to DC cut the frequency of 0.1 Hz or less, the component of 0.1 Hz cannot be discriminated until 10 seconds have passed, and this time is required for stabilization. Similarly, it takes 10 seconds for the integrator to stabilize. Seconds are required, but D with a frequency of 1 Hz or less
This is because 1 second is required for both C-cut and integration over 1 Hz.

However, DC with a frequency of 1 Hz or less
In the case of the characteristic of cutting and integrating 1 Hz or more, the low frequency component in the camera shake is cut, and the image stabilization characteristic deteriorates. Therefore, it is not suitable for confirming the image stabilization on the finder like the "first mode" (the mode in which the image stabilization is started from the generation of the SW1 signal), and the time constant setting means 31 is the image stabilization start selecting means. Only when the "second mode" signal is input from 16 (the mode in which the image stabilization is performed only during the exposure and the image stabilization is not confirmed on the finder), the time constant of the sensor output calculation unit of the vibration detection unit 91 is changed.

As described above, when the time constant is made smaller, the low frequency component in the camera shake is cut and sufficient image stabilization cannot be achieved. However, when the shutter speed is fast, that is, when the exposure period is short, the amount of shake that is originally recorded on the image surface is small, so there is no need to perform sufficient image stabilization, and similarly when the focal length is short Since there are few, sufficient vibration isolation is not required, but instead the time until stabilization of vibration isolation is shortened.

FIG. 10A is a flow chart showing the operation of the time constant setting means 31. This operation starts at the same time as the start of the image stabilization, and the vibration detecting means 9 only in the "second mode".
The time constant of the sensor output calculation unit 1 is changed.

In step 4001, "second mode"
It is judged whether or not, and only in the "second mode", step 4
Proceed to 002. Then, in the next step 4002, the shutter speed Tv is input, and then in step 4003, the focal length f ₁ by the focus zoom is input. In the following step 4004, the product a of the shutter speed Tv and the focal length f ₁ is obtained.

In the next step 4005, the product a and the constant value a ₁ (= 5) are compared, and if the product is smaller than a ₁ (that is, the product of the shutter speed Tv and the focal length f ₁ is less than a constant). When the time goes to step 4011, the fourth time constant [in FIG. 10 (b), the time constant τ when a is 5 to 1]
(0.16)] is set. If it is larger than a ₁ , the process proceeds to step 4006, where it is compared with a _2, and as a result,
If it is smaller than a ₂ , the process advances to step 4010 to set the third time constant. If a ₂ or more, step 400
Advances to 7, wherein compared to a _3, to step 4009 if less than a _3, step 4008 if a ₃ or more
Proceed to and set the second time constant or the first time constant.

Here, when the image stabilization determination means 23 determines that the image stabilization is unnecessary, the image stabilization is not performed even if the time constant is set.

With the above-mentioned structure, the time of unstable image stabilization can be shortened in the "second mode", and quick shooting can be endured.

The third embodiment described above has the following effects.

1) As the judgment material of the image stabilization judgment means 23,
Since the focal length variation due to focus and the shake angular velocity information are also taken into consideration, it becomes possible to more accurately determine whether or not the image stabilization is necessary or not.

2) By providing the time constant setting means 31,
When the shutter speed is fast in the "second mode" (for example, 1 /
60 or more) or when the focal length is short (for example, 100 m
In the case of (m or less) etc., it is possible to shorten the waiting time until stabilization of image stabilization and improve the quick-shooting property.

(Fourth Embodiment) FIG. 11 is a block diagram showing the arrangement of the essential parts of an image stabilizing camera according to the fourth embodiment of the present invention. The same parts as those in FIG. 7 are designated by the same reference numerals. .

The difference from the above-mentioned third embodiment (FIG. 7) is that the "first mode" and "second mode" described so far are not selected by the photographer but are set automatically. There is a point to do.

In the "second mode", that is, in the mode in which the image stabilization is performed only during the exposure, the image stabilization is not performed in the framing before the photographing, which is suitable for the frequent framework and panning ( If you use vibration isolation during framing, you will not be able to use framing as it will even framing. Further, when shooting is performed with frequent framework and panning, shooting is not performed at a slow shutter speed. This is because a proper photograph cannot be taken even if the slow shutter photographing is performed on a moving subject that requires frequent framework and panning, and such photographing is not generally performed. Therefore, when the shutter speed is equal to or higher than a certain level, the "second mode" is automatically changed to improve the operability.

Further, when the focal length is short, the actual shake becomes difficult to understand, so that it is difficult to understand the effect even if the vibration is prevented. In such a case, it is possible to save power by automatically setting the "second mode" and performing image stabilization only during shooting.

In FIG. 11, shutter speed information is input from the exposure preparation means 96 to the image stabilization start judgment means 41, and zoom focal length information is input from the image stabilization sensitivity setting means 94. The image stabilization start judgment means 41 selects the "first mode" or the "second mode" based on these two pieces of information.

FIG. 12 is a flow chart showing the "first mode" and "second mode" selection operations of the image stabilization start judgment means 41. This flow starts at the same time when the image stabilization switching means 912 is turned on.

In step 5001, the shutter speed Tv is set, and in the next step 5002, focus,
Enter the lens focal length f ₁ by zooming,
In the following step 5003, their product a (Tv ×
f ₁ ) is calculated, and the product a is a constant value a ₁ or more (that is,
When the shutter speed is slow or the focal length is long), the process returns to step 5001 and the flow is circulated. At this time,
The switch piece 16a of the image stabilization start selecting means 16 is a contact 16b.
Anti-vibration is the "first mode" because it remains connected to
become.

If the product a is a constant value a ₁ or less (when the shutter speed is fast or the focal length is short), step 5005
Then, it is determined whether or not there is an output from the activation determination canceling means 42. The activation determination canceling means 42 (the signal of which is input to the image stabilization activation determining means 41) is a switch ("second mode" for forcibly fixing the image stabilization "first mode" by the photographer's operation.
If you do not want to switch to the mode of "), and if this output is output, step 5005 to step 500 again.
Return to 1. If there is no output, step 5006
Then, the process proceeds to step 5001 to connect the switch piece 16a of the image stabilization start selecting means 16 to the contact 16a to set the image stabilization to the "second mode", and the process returns to step 5001.

Note that in FIG. 12, the product (logical product) of the shutter speed Tv and the lens focal length f ₁ is the "first mode",
While making a selection decision of the "second mode" is not limited to this, Tv, when one of f ₁ is suitable for "second mode" (or shutter speed is high, the focal point The "second mode" may be selected and determined when the distance is short), or the selection and determination may be performed based only on information on either the shutter speed or the focal length.

The above-mentioned fourth embodiment has the following effects.

1) "First mode", "Second mode"
Since not only the operation of the photographer but also the camera can be automatically selected, it is possible to concentrate on the photography without forcing the photographer to perform a troublesome operation.

2) Automatic selection of "first mode" and "second mode" because a switch for forcibly fixing to "first mode" is provided to prevent automatic selection. It was also possible to stop the shooting and accurately convey the will of the photographer to the camera.

(Fifth Embodiment) In the first to fourth embodiments, the release means 911 of the camera is the switch S.
It is a two-step switch of W1 and SW2 (switches for generating SW1 and SW2 signals), and the image stabilization timing is changed depending on which switch is used to perform the image stabilization.

In the fifth embodiment shown in FIG. 13, this is used as a release means 911-1 consisting of a three-step switch, and a switch SW1 for shooting preparation (corresponding to SW1 up to now) is provided. A dedicated switch SW2 for exposure and a switch SW3 for exposure (corresponding to SW2 up to now) are configured. Then, if the switches SW1 and SW2 are pushed in advance, the image stabilization is started at the time of preparation for shooting as in the first mode so far, and if only the switch SW1 is pressed, the image stabilization start is delayed (SW2 and SW3 are simultaneously pressed. And it will be the same as the second mode up to now).

The release means 911-1 shown in FIG.
As shown in FIG. 4, when the button 52 is pushed in, the contact piece 53 moves the terminal 5
4 is connected to generate SW1 signal, and when pushed further, contact piece 5
3 is connected to terminals 54 and 55 to generate SW1 and SW2 signals, and when pushed down, the contact piece 53 is connected to terminals 54, 55 and 56 to generate SW1, SW2 and SW3 signals.

With the above arrangement, the release means 911-
Although the photographer can freely control the start timing of the image stabilization by pressing 1, SW2 (start image stabilization)
When and SW3 (exposure) are pressed almost at the same time, exposure will be performed from the start of image stabilization until the image stabilization is stable.

Therefore, as shown in FIG. 13, a switch speed detecting means 51 is provided to monitor the time between the SW2 signal generation and the SW3 signal generation, and the time is shorter than a certain value, and the image stabilization is unstable. When there is a possibility of being exposed in the middle, a signal is output to the release time lag adjusting means 14-1,
The release time lag (time from SW3 to exposure) is lengthened to perform exposure after stabilization of image stabilization.

The above-mentioned fifth embodiment has the following effects.

1) By making the release means the same member in three stages, the photographer can freely control the image stabilization start time only by operating the release means (without operating a special switch), and the operability is improved. Is improved.

2) In the case where the switches SW2 and SW3 are simultaneously pressed, the release time lag is lengthened, so that exposure can be prevented before the image stabilization is stable.

In the fifth embodiment, the SW1 signal is generated to prepare for exposure, the SW2 signal is generated to start image stabilization, and the SW3 signal is generated to start exposure. However, when the SW1 signal is generated, image stabilization is started and SW2 is started.
Exposure preparation may be performed by signal generation, and exposure may be started by SW3 signal generation.

(Sixth Embodiment) FIG. 15 shows an image stabilizing camera according to a sixth embodiment of the present invention. The same parts as those in FIG.

The difference from FIG. 13 is that in the fifth embodiment, the vibration detecting means 9 is activated at the same time when the SW2 signal is generated, the locking means 914 releases the locking of the correcting means 910, and the correcting means is released. Fig. 1 shows that the camera was driven for shake correction.
In the sixth embodiment shown in FIG. 5, when the SW1 signal is generated, the vibration detecting means 91 has already been activated to stabilize the output, the locking of the correcting means 910 is also released, and the correcting means 910 is in the drive control state (electromagnetic wave). Keep it in the neutral position) to speed up the responsiveness.

In FIG. 15, the SW1 signal is input to the vibration detecting means 91, and the vibration detecting means 91 is activated at the same time when the SW1 signal is generated. Further, the SW1 signal is also input to the logical product means 21, and when there is an output of the image stabilization switching means 912 (when the image stabilization system is used), the AND gate 21.
a outputs a high-level signal, causes the locking means 914 to unlock the correction means 910, turns on the correction activation means 98, and puts the correction means 910 in a drive control state (no shake correction drive is performed).

With such a structure, the image stabilization can be directly performed when the SW2 signal is generated.

Incidentally, when the switches SW1, SW2 and SW3 are simultaneously pressed, there is a possibility that the exposure may be performed before the image stabilization is stable. Therefore, the switch speed detecting means 51
Monitors the time from the generation of the SW1 signal to the generation of the SW3 signal, and instructs the release time lag adjusting means 14-1 to lengthen the release time lag when the time is less than a certain value.

In the example of FIG. 15, activating the vibration detecting means 91 by generating the SW1 signal does not consume much power, but driving the correcting means 910 by generating the SW1 signal requires some power. . Therefore, in order to save power, the vibration detection means 91 is activated by the generation of the SW1 signal, but the lock release and drive control of the correction means 910 may be performed by the generation of the SW2 signal.

FIG. 16 shows such an example. What is different from FIG. 15 is that the locking means 914 and the correction starting means 98 are the logical product means 9
9 and the logical product means 99.
Is output when the SW2 signal of the release means 911-1 and the signal of the image stabilization switching means 912 are being generated, the correction means 910 generates the SW2 signal when the image stabilization system is used (when the image stabilization switching means 912 is on). The lock is released by and the shake correction drive is performed. With such a configuration, power saving can be achieved.

The sixth embodiment described above has the following effects.

1) Since the vibration detection means is activated by the SW1 signal generation and the correction means is driven and controlled, the time from the generation of the SW2 signal to the stabilization of the image stabilization can be reduced.

2) Since the vibration detection means is activated by the SW1 signal generation and the correction means is driven by the SW2 signal generation, power is saved.

(Seventh Embodiment) FIG. 17 shows an anti-vibration camera according to the seventh embodiment of the present invention. The same parts as those in FIG. 15 are designated by the same reference numerals.

A difference from FIG. 15 is that the release means 911.
The role of -1 is "second mode" of "SW1: exposure preparation, SW2: image stabilization start, SW3: exposure", and "SW1:
"Image stabilization start, SW2: exposure preparation, SW3: exposure"
There is a point that it can be switched to the "mode".

In FIG. 17, release means 911-1.
The SW1 signal of is input to the vibration detection means 911 to activate the vibration detection means 91, and at the same time, the vibration isolation start selection means 71.
And the SW2 signal is also input to the image stabilization start selection means 71.
Has been entered in. Then, the image stabilization start selection means 7 is normally used.
The first switch piece 71a is connected to the contact 71c, and the switch piece 71b is connected to the contact 71f.

Therefore, the SW1 signal is the switch piece 71a,
When input to the logical product means 99 via the contact 71c and the image stabilization switching means 912 is on (main switch of the image stabilization system), the logical product means 99 outputs a signal and the target value setting means. The target value is output from 92 to start the image stabilization (the logical product means 21 outputs the SW1 signal and the signal of the image stabilization switching means 912 regardless of the state of the image stabilization start selection means 71, and the locking means 914 The correction means 910 is unlocked, and the correction start means 98 brings the drive control state. That is, the image stabilization is started by the generation of the SW1 signal.

The SW2 signal is a switch 71b and a contact 71f.
It is input to the exposure preparation means 96 via (1) to perform photometry and focus measurement drive.

As described above, normally, the image stabilization starts when the SW1 signal is generated, and the exposure preparation "first mode" is started when the SW2 signal is generated. In this "first mode", the camera shake is so great that proper framing cannot be performed on the subject, and therefore distance measurement cannot be performed correctly (when the camera shake is too large and the distance measurement frame does not reach the desired point of focus). Sometimes it is a valid mode.

The image stabilization start selection means 71 is operated by the photographer, and the switch piece 71a is connected to the contact 71d and the switch piece 71b is connected to the contact 71f by the operation of the photographer.
Can be connected to.

In FIG. 17, the switch piece 71a and the contact point 71d and the switch piece 71b and the contact point 71f are simultaneously connected by the photographer's operation, but both may be operated individually.

When the photographer operates the image stabilization start selection means 71 in this way, the SW1 signal is input to the exposure preparation means 96 via the switch piece 71a and the contact point 71d to perform photometry,
Focusing drive is performed, and exposure preparation is started. SW2
The signal is input to the logical product means 1 (99) via the switch piece 71b and the contact 71e, and the image stabilization is started.

That is, the same configuration as that of FIG.
The second mode is suitable for framing and panning, in which exposure preparation is performed by signal generation and image stabilization is started by SW2 signal generation.

The contacts 71d of the image stabilization start selecting means 71,
The signal via 71e and the SW3 signal of the release means 911 are input to the switch speed detection means 511. When the time from the start of image stabilization to the exposure is short, the release time lag adjusting means 14-1 increases the release time lag to prevent the exposure. This prevents exposure before the shake is stable.

The signal of the mode switching means 11 is also input to the image stabilization start-up selection means 71, and when the "real-time exposure mode" is selected, the switch pieces 71a, 71 are respectively provided.
b is not connected to the contacts 71d and 71e (the "second mode" is not set) so that the exposure is performed during unstable vibration isolation (the "real-time exposure mode" is the time from the generation of the SW3 signal to the exposure). Because it is extremely short, the vibration control start SW immediately
In 3 operations, it exposes while the image stabilization is unstable).
If the "real-time exposure mode" is selected while the "second mode" is selected by the image stabilization start-up selection means 71, the "second mode" is returned to the "first mode" (switch piece 71a). , 71b are respectively connected to the contacts 71c, 71f).

The RT warning means 18 is the image stabilization start selection means 71.
"Real-time exposure mode", and
When the "second mode" is selected, a warning is given that the "first mode" will be entered.

The anti-vibration mode display means 17 also inputs the anti-vibration activation selection means signal to display the selected mode, and the photographer can judge by the display whether or not it is necessary to select the mode for the next photography. I am doing it.

The seventh embodiment described above has the following effects.

1) "1st mode" in which the image stabilization starts when the SW1 signal is generated, the exposure is prepared when the SW2 signal is generated, the exposure is prepared when the SW3 signal is generated, the exposure is prepared when the SW1 signal is generated, and the image stabilization is started when the SW2 signal is generated. "Second mode" of exposure by signal generation
Since it is possible to select, "first mode" and "second mode" can be selected depending on the case where precise distance measurement is required, framing, panning, etc. improves.

2) "Real-time exposure mode" and "second
It is possible to prevent exposure while the image stabilization is unstable by adopting a configuration that avoids compatibility of both modes.

3) When the time from the start of image stabilization to the exposure is short, the release time lag is set to be long, so exposure can be prevented during unstable image stabilization.

4) By displaying the selected mode,
This makes it easier to respond to the next shooting.

(Eighth Embodiment) FIG. 18 is a block diagram showing the arrangement of the essential parts of an image stabilization camera according to the eighth embodiment of the present invention. The same parts as those in FIG. 17 are designated by the same reference numerals. is there.

The difference from FIG. 17 is that the time constant setting means 81
Is provided.

The focal length information from the image stabilization sensitivity setting unit 94 and the shutter speed information from the exposure preparation unit 96 are input to the time constant setting unit 81, and the image stabilization start selection unit 7 is input.
When 1 is outputting the second mode signal (inputting to the time constant setting means 81), the same flow as in FIG. 10A starts and the sensor output calculation means of the vibration detection means 91 Change the time constant. Therefore, in the "second mode", the SW2 signal is generated to set the time constant in accordance with the shutter speed focal length, so that the time until stabilization of image stabilization is extremely short.

Of course, even in the "second mode", SW2
During the time from the signal generation to the start of the operation of the switch SW3, the photographer can know the anti-vibration effect through the viewfinder, and the photographer recognizes that the anti-vibration effect is low by changing the time constant. However, if it is desired to obtain a greater image stabilization effect, the time constant change prohibiting means 82 may be operated to restore the set time constant of the time constant setting means 81, or to return to the "first mode".

The image stabilization start selection means 71 is not limited to the photographer selection, but the image stabilization start determination means 4 as described in FIG.
1 may be provided and the camera may be automatically selected.

According to the eighth embodiment described above, since the time constant setting means for changing and setting the time constant in the "second mode" is provided, the time until stabilization of image stabilization can be shortened.

The output of the time constant setting means 81 (when the time constant is changed) is input to the release time lag adjusting means 14, and the delay amount of the release time lag is adjusted by this, and the stabilization of vibration stabilization is accelerated. At the same time, the release time lag delay time is also shortened.

(Modification) In the present invention, as the vibration detecting means, an angular accelerometer, an accelerometer, an angular velocity meter, a speedometer, an angular displacement meter, a displacement meter, or a method for detecting the image shake itself is used. Anything that can be detected may be used.

Further, in the present invention, the vibration detecting means and the correcting means can be separately provided in a plurality of devices which can be attached to each other, for example, a camera and an interchangeable lens which can be attached thereto.

Further, in the present invention, each structure or a part of structures of the claims or the embodiments may be provided in a separate device. For example, the vibration detection means may be provided in the camera body, the correction means may be provided in the lens barrel mounted in the camera, and the control means for controlling them may be provided in the intermediate adapter.

Further, in the present invention, as the correcting means, a shift optical system for moving an optical member in a plane perpendicular to the optical axis, a light flux changing means such as a variable apex angle prism, or a photographing surface in a plane perpendicular to the optical axis. Any device that can prevent the shake, such as a device that moves the camera, a device that corrects the shake by image processing, may be used.

Furthermore, the present invention can be applied to any camera such as a single-lens reflex camera, a lens shutter camera, and a video camera.

Further, the present invention may be constructed by appropriately combining the above-mentioned claims, the respective examples, or the techniques thereof.

[0267]

As described above, according to the present invention,
There is provided image stabilization mode setting means for setting either the first mode or the second mode based on the shutter speed information, the lens focal length information, or the calculated values of the shutter speed and the lens focal length. , Lens focal length information, or
The image stabilization start time is automatically set based on the calculated values of the shutter speed and the lens focal length.

Therefore, the operability for setting the image stabilization start time can be improved.

Further, according to the present invention, when the second mode is selected, the release time lag adjusting means for adjusting the time from the turning on of the second switch means to the start of exposure is provided.
