Description

Detailed Description of the Invention (Field of Application of the Invention) The present invention is mounted on a camera to detect vibrations (camera shake) at a frequency of about IH2 to 121 (Z), and use this as information to prevent image blurring. This invention relates to an improvement of a camera anti-shake device that prevents camera shake.

(Background of the invention) The prior art to which the present invention is applied will be explained below.

In modern cameras, important tasks such as exposure determination and focus adjustment are completely automated, so even those who are inexperienced in operating the camera are less likely to make a shooting mistake. It was considered difficult to automatically prevent failures in shooting due to camera shake.

Therefore, in recent years, there has been active research into cameras that can prevent shooting failures caused by camera shake, and in particular, the development of cameras that can prevent shooting failures due to camera shake. Research is underway.

The camera shake mentioned above during shooting is usually at IH2 as a frequency.
This is a vibration of 12Hz to 12Hz, but in order to be able to take pictures without image blur even if such camera shake occurs at the time of shutter release, the basic idea is to reduce the camera vibration caused by the camera shake. It is necessary to detect this and displace the correction lens according to the detected value. Therefore, in order to achieve the above purpose (i.e., to be able to take photographs that do not cause image blur even if camera movement occurs),
First, it is necessary to accurately detect camera vibration and correct optical axis changes due to camera shake.

In principle, this vibration (camera pre-detection) is detected using a vibration sensor that detects angular acceleration, angular velocity, etc., and a camera pre-detection system that electrically or mechanically integrates the sensor signal and outputs the angular displacement. This can be done by installing it on the camera. Then, based on this detection information, a correction optical mechanism that decenters the photographing optical axis is driven to suppress image pretension.

Here, an outline of an image pre-suppression system (vibration isolation system) using an angular velocity meter will be explained using FIG. 17.

The example in FIG. 17 shows the vertical camera shake 71 in the direction of the arrow 71 in the figure.
FIG. 7 is a diagram of a system for suppressing image blur caused by camera shake 71y and horizontal camera shake 71y. In the figure, 72 is a lens barrel, 73
p and 73y are angular velocity meters that detect the camera vertical angular velocity and camera lateral angular velocity, respectively, and the respective angular velocity detection directions are indicated by 74p and 7'4y. 75p, 75. y is a known analog integration circuit, and angular velocity meters 73p, 73
The signal of y is integrated and converted into an angular displacement of the hand, and the signal drives the correction optical system 76 (77p and 77y are respective drive units thereof, and 78p and 78y are correction optical position detection sensors), and the image plane 79 is ensure the stability of

Incidentally, it is also possible to provide the correction optical mechanism itself with a mechanical integration function and omit the above-mentioned analog integration circuit.

In the above system, the angular velocity meters 73p and 73y, which are the vibration detection means, detect the angular velocity of camera shake, and integrate this output to obtain the pre-displacement angle, and adjust the correction optical system accordingly. 76 must be driven.

Figure 18A shows the Bode diagram of the integral characteristic to be found, and the gain 81 is from 0.182 or more to the integral characteristic (20C
It has a first-order integral characteristic of dB/decE).

As mentioned above, camera shake has a frequency of about 1) IZ to 12H2, so it seems to be sufficient to integrate over 1i (Z) as an integral characteristic, but as shown in Figure 18B, 187
If the above is made into an integral characteristic, regardless of the gain 83, the phase 84 does not have a sufficient integral characteristic (phase delayed by 90 [d+4] with respect to the input angular velocity) near IHz, which is the target of an anti-shake camera. “Using 300mm lens, l
In order to prevent image blur in /8sec slow shutter, accurate vibration isolation cannot be achieved with such a large phase shift.When the shift of phase 82 in the radiated blur frequency band is small, as shown in Fig. 18A. A characteristic with a large constant (the time constant is larger as the bending point of the gain 81 curve in the Bode diagram is on the lower frequency side) is used.

FIG. 19 shows a circuit that creates such a characteristic, in which a resistor 87 and a capacitor 86 are negatively fed back to an operational amplifier 85 in parallel. The above-mentioned time constant increases as the resistance value of the resistor 87 and the capacitance of the capacitor 86 increase.

In FIG. 19, when the angular velocity signal is input to the terminal 88, the pre-displacement angle is output from the terminal 89, and the 18th
As shown by phase 82 in Figure A, 1) Precision of angles greater than or equal to IX is guaranteed, but when a circuit with such a large time constant is used, the following problems occur.

A large time constant means that it takes a long time for the output to stabilize. For example, the bending point in FIG. 18A is 0.
When it is at 1H2, the time constant is 1.59, and it is necessary to wait 2 seconds until the output stabilizes to some extent.

This is illustrated graphically. In FIG. 20, with respect to the center 810a of camera shake 810 shown by a sine wave. The angular velocity meter detects the hand angular velocity from arrow 811, and the output is set to a time constant of 1.
At the center 812a of the waveform 812 obtained by integrating the camera shake using the No. 59 integrating circuit, a low frequency error is superimposed. This is the error until the output stabilizes, and if you shoot when this error occurs (from the point of arrow 813), the amount of image blur indicated by diagonal line 814 will remain as image blur within the exposure time. become. Therefore, in order to obtain a photograph with accurate image blur correction, the photographer must wait until the output stabilizes.

However, if the photographer does not know how long it takes for the output to stabilize, he or she may end up taking a picture before the output stabilizes, resulting in a photo that has not been corrected for blur, or conversely, waiting too long and missing a photo opportunity. Things also happen.

(Objective of the Invention) An object of the present invention is to solve the above-mentioned problems and to provide a camera anti-shake device that eliminates the risk of failing to take a picture or missing a photo opportunity.

(Known of the Invention) In order to achieve the above object, the present invention provides a detection means for detecting the stability of the vibration isolation output of the vibration detection means, and a notification means for notifying the stability state detected by the detection means. The present invention is characterized in that the present invention is characterized in that the present invention is characterized in that it is configured to notify the photographer of the stability state of the image stabilization output.

(Embodiments of the Invention) Hereinafter, the present invention will be described in detail based on illustrated embodiments.

"Step 203" Here, it is also waited for the count value of the timer 103 to exceed a for a predetermined time (the time during which the output from the anti-vibration system 102 becomes stable (for example, 10 times the integral time constant)). Then, after the predetermined time, a is set to the timer 103.
When the count value exceeds, the timer 103 outputs “
A signal of H'' is output, and the process advances to step 204.

With this configuration, it is possible to prevent failures caused by photographing before the anti-vibration output stabilizes, or "missed photo opportunities" caused by waiting too long.

In this first embodiment, the anti-vibration status display unit 105 lights up after the anti-vibration output is stabilized, but the invention is not limited to this. ) and turns off after stabilization" or "Flashes before stabilization, turns on after stabilization J, U Warning sound before stabilization, no sound after stabilization"
Various other methods are possible.

FIG. 4 is a block diagram showing a second embodiment of the present invention, and the same parts as in FIG. 1 are given the same reference numerals. In addition, the above-mentioned first embodiment refers to the time it takes for the anti-vibration output to stabilize;
That is, the difference is that the time until photography becomes possible is displayed in stages.

In FIG. 4, 111 is a timer that starts counting when the timer switch TIMESW, which operates in synchronization with the anti-vibration switch JSSW, is turned on and outputs a timer time t that constantly changes. 2. te3
(There is a relationship of 1 < 2 < 3, where 3 is the previous predetermined time equal to a) and the timer time t input from the timer 111. in.

7. The comparator 113 outputs an "H" signal every time the value exceeds 3, and each time a trigger signal is input from the trigger means 104, it is possible to take a photograph as shown in FIGS. This is an anti-vibration state display section that displays the state of vibration reduction in stages.

Next, the operation will be explained using the flowchart shown in FIG.

``Step 4o1'' First, the photographer sets the anti-shake switch l.
Wait for the 5SW to be turned on, and then proceed to step 402.

"Step 402" Since the timer switch TIMESW is also turned on in synchronization with the anti-vibration switch l5SW, the timer 111 is activated.

"U step 403" Here, it is also waited for the count value of the timer 111 to exceed 1 in the first predetermined time. Then, when the count value of the timer 111 exceeds 1 for the predetermined period of time, the timer 111 outputs an "H" signal, and the process proceeds to step 404.

"Step 404" The trigger means 104 is activated because the "H" signal is input from the timer 111, and a trigger signal is output from the trigger means 104 to the anti-vibration state display section 113, and the process proceeds to step 405.

"Step 405" Since a trigger signal is input from the trigger means 104, a part of the display section of the image stabilization state display section 113 arranged in the finder 301 lights up as shown in FIG. 6(a).

"Step 406" Here, it is also waited for the count value of the timer 111 to exceed 2 in the second predetermined time. Then, when the count value of the timer 111 exceeds 2 for the predetermined period of time, the timer 111 outputs a signal of "H", and the process proceeds to step 407.

"Step 407" The trigger means 104 is activated because the "H" signal is input from the timer 111, and a trigger signal is output from the trigger means 104 to the anti-vibration state display section 113, and the process proceeds to step 408.

"Step 408" Since a trigger signal is input from the trigger means 104, some of the display parts (more than the number of displays in step 405) of the anti-vibration state display part 113 are displayed as shown in FIG. 6(b). lights up.

"Step 409" Here, it is also waited for the count value of the timer 111 to exceed 3 at the third predetermined time. Then, when the count value of the timer 111 exceeds 3 for the predetermined period of time, the timer 111 outputs an "H" signal, and the process proceeds to step 410.

"Step 410" The trigger means 104 is activated because the "H" signal is input from the timer 111, and a trigger signal is output from the trigger means 104 to the anti-vibration state display section 113, and the process proceeds to step 411.

"Step 411" Since a trigger signal is input from the trigger means 104, all the display sections of the anti-vibration state display section 113 light up as shown in FIG. 6(c). With all the lights on, the photographer can know that the camera is ready to take pictures.

With this configuration, the photographer is informed of the remaining waiting time, which reduces the mental burden on the photographer.

In addition, in this second embodiment, FIG. 6(a) fb)(
As shown in c), an incremental display format is used, but it may also be a subtractive format, a step-by-step single color tone, or a combination thereof.

FIG. 7 is a block diagram showing a third embodiment of the present invention, and the same parts as in FIGS. 1 and 4 are given the same designations. Note that this embodiment differs from the above embodiment 1.2 in that the image stabilization state is displayed only when the release button is pressed halfway.

In FIG. 7, 121 is a timer 1 at the time when the switch SWI is turned on by pressing the release button halfway.
Timer time t from 11 (anti-vibration switch l5SW is ON)
A sample and hold circuit 122 that holds the elapsed time since the sample and hold circuit 121 compares the sample time tsH output from the sample and hold circuit 121 with the predetermined time a, and while the relationship tg14<τa holds, " This is a comparison circuit that outputs a signal of "H".

Next, the operation will be explained using the flowchart shown in FIG.

"Step 501" First, the photographer sets the anti-shake switch l.
Wait for the 5SW to be turned on, and then proceed to step 502.

"Step 502" Since the timer switch TIMESW is also turned on in synchronization with the anti-vibration switch l5SW, the timer 111 is activated.

"Step 503" Here, the release button is pressed halfway and the switch SWI is turned on. When the switch SWI is turned on, the process proceeds to step 504.

"Step 504" Since the switch SWI is turned on, the sample hold circuit 121 immediately starts the timer 1.
Sample the current timer time t from 11 to the sample time ts)l
hold as.

"Step 505" Here, the sample time tiH held by the sample and hold circuit 121 is compared with a at a predetermined time, and while the result is in the relationship tsH<τa, the comparator 122 outputs "H". A signal is output and the process proceeds to step 506.

On the other hand, if the relationship tsH>a holds true, that is, if the image stabilization output is stable, this operation is ended without displaying the image stabilization state (display that photography is not possible).

"Step 506" The trigger means 104 is activated because the "H" signal is input from the comparator 122, and a trigger signal is output from the trigger means 104 to the anti-vibration state display section 105, and the process proceeds to step 507.

"Step 507" Since a trigger signal is input from the trigger means 104, the image stabilization state display section 105 lights up, and a state in which photography is not possible (that photography accuracy is low) is displayed to the photographer.

With this configuration, the image stabilization status is displayed only when the photographer presses the release button halfway, and is not displayed at other times, which not only eliminates inconvenience, but also dramatically reduces the display period. It can prevent battery consumption.

FIG. 9 is a block diagram showing a fourth embodiment of the present invention, and the same parts as in FIG. 7 are given the same reference numerals.

Note that this embodiment differs from the third embodiment in that the release switch SW2 is not turned on until the anti-vibration output is stabilized, and the release operation is prohibited. To explain in more detail, the third
In the above embodiment, while the relationship tie < te a, a display indicating that shooting is not possible (indicating that the shooting accuracy is low) is displayed, but even in this state, the release switch SW2 is not turned on.
However, in this fourth embodiment, the receiver is not attached when the release switch SW2 is turned ON unless the relationship a is established at t118>.

In FIG. 9, 131 is a sample and hold circuit 121.
The sample time tsH output from and the predetermined time τ
A comparison circuit 132 outputs an "H" signal to the trigger circuit 104 and exposure control means to be described later while the relationship t88<τa holds.
While the signal `` is being input, even if the release button is pressed all the way down, the exposure control means does not turn on the release switch SW2 and prohibits the release operation (exposure operation).

Next, the operation will be explained using the flowchart shown in FIG. 1o, but only the parts that are different from the third embodiment will be explained here.

In step 505, the sample hold circuit 1
The sample time taH held by 21 is compared with a at a predetermined time, and as long as the result is in the relationship too<a, an "H" signal is output from the comparator 122, and the third implementation As in the example, proceed to steps 506 and 507,
An image stabilization status display (impossible to shoot) is displayed. On the other hand, t
If the relationship is so > a, that is, if the anti-vibration output is stable, the "H" signal output of the comparator 131 is stopped, so the release switch SW2 is turned ON, and the step By configuring the release operation in this way using 510, even if the photographer performs a release operation carelessly, the release is prohibited until the anti-shake output is stabilized, thereby eliminating failed photographs.

FIG. 11 is a block diagram showing a fifth embodiment of the present invention, and the same parts as in FIG. 9 are given the same reference numerals.

In this fifth embodiment, i is changed at a predetermined time corresponding to a in the above-mentioned predetermined time depending on the set shutter speed. This will be explained again using FIG. 20.

In FIG. 20, as the shutter speed T becomes shorter, the diagonal line error 814 becomes smaller; for example, r300mm J
When the shutter speed of the lens is "1/1.50", the error 814 is not so large even if the time from the anti-shake system activation (arrow 811) to exposure is less than 1 second, and it is not a problem for service size prints. If you try to obtain the same level of precision with shutter speeds r1/60J and rl/8J, the waiting times will be different. Taking this into consideration, i is changed at a predetermined time.

In FIG. 11, 141 is a shutter speed setting unit for setting an arbitrary shutter speed, and 142 is a predetermined time i (1°, 1°, 2.・・・・・・)
A predetermined time setting unit 143 compares the timer time t from the timer 111 with i at the predetermined time, and calculates t and τ.
A comparator circuit that outputs an "H" signal while in a relationship of i, 1
Reference numeral 44 denotes a release lock means for inhibiting the release operation while a trigger signal is input from the trigger means 104.

Next, the operation will be explained using the flowchart shown in FIG.

"Step 601" First, the photographer turns on the anti-shake switch.
Wait for the 5SW to be turned on, and then proceed to step 602.

"Step 602" Since the timer switch TIMESW is also turned on in synchronization with the anti-vibration switch l5SW, the timer 111 is activated.

"Step 603" Here, the shutter speed set by the shutter speed setting section 141 is, for example, r.
1/60J, the predetermined time 1:12 (-ci) set by the predetermined time setting unit 142 is compared with the timer time t, and while the result is in the relationship t<τi, The comparator 143 outputs an "H" signal, and the process proceeds to step 604.

On the other hand, if the relationship is i at t>, that is, if the anti-vibration output is stable, this operation is ended without displaying the anti-vibration state and prohibiting the release.

"Step 604" The trigger means 104 is activated because the "H" signal is input from the comparator 143, and a trigger signal is output from the trigger means 104 to the anti-vibration state display section 105, and the process proceeds to step 605.

"Step 6o5" Since a trigger signal is input from the trigger means 104, the image stabilization state display section 105 lights up, and a state in which photography is not possible is displayed to the photographer.

"Step 606" Since the trigger signal is also input from the trigger means 104 to the release lock means 144,
Here, the release operation is prohibited by the means 144.

With such a configuration, the anti-vibration output stabilization waiting time is made variable depending on the set shutter speed, so at a regular shutter speed (about rl/60J), the waiting time is short, and the chance of missing a photo opportunity is reduced.

FIG. 13 is a block diagram showing a sixth embodiment of the present invention, and the same parts as in FIG. 11 are given the same reference numerals. This embodiment differs from the fifth embodiment in that the shutter speed is replaced with zoom information.

In FIG. 13, 151 is a zoom information setting unit for setting arbitrary zoom information, and 152 is a predetermined time τi, which is a stabilization wait time for the anti-vibration output according to the input zoom information.
(te21+te22...) (for example, when the zoom information is 50mm, it is 300m
i is made shorter by a predetermined time compared to the time of m. This is because the deterioration of the image due to camera shake is greater with a telephoto lens, and the closer the lens is to the wide-angle side, the less the image degradation due to camera shake becomes. ), 153 compares the timer time t from the timer 111 with i at the predetermined time, and while there is a relationship between t and τi, "H" is set.
This is a comparison circuit that outputs a signal of ``.

Next, the operation will be explained using the flowchart shown in FIG.

"Step 701" First, the photographer turns on the anti-shake switch r.
Wait until ssw is turned on, and then proceed to step 702.

"Step 702" Since the timer switch TIMESW is also turned on in synchronization with the anti-vibration switch l5SW, the timer 111 is activated.

“Step 703” Here, the zoom information setting section 151
If the zoom information set by is rroommJ, for example, 22(tei) is compared with the timer time t at a predetermined time set by the predetermined time setting section 142, and the result is t Comparator 15 while in the relationship i.
3, an "H" signal is output, and the process advances to step 704.

On the other hand, if the relationship is i at t>, that is, if the anti-vibration output is stable, this operation is ended without displaying the anti-vibration state and prohibiting the release.

"Step 704" The trigger means 104 is activated because the "H" signal is input from the comparator 153, and a trigger signal is output from the trigger means 104 to the anti-vibration state display section 105, and the process proceeds to step 7.5. .

"Step 705" Since a trigger signal is inputted from the trigger means 104, the image stabilization state display section 105 lights up, and a state in which photography is not possible is displayed to the photographer.

"Step 706" Since the trigger signal is also input from the trigger means 104 to the release lock means 144,
Here, the release operation is prohibited by the means 144.

With this configuration, the anti-vibration output stabilization wait time can be changed depending on the zoom setting information, so when using a regular zoom lens, the wait time is shorter than when using a long focal length lens, and there are fewer opportunities to miss a photo opportunity. Become.

FIG. 15 is a block diagram showing a seventh embodiment of the present invention, and the same parts as in FIGS. 11 and 3 are given the same reference numerals. This embodiment has a configuration that combines the fifth embodiment and the sixth embodiment, that is, i is made variable over a predetermined period of time, which is the anti-shake output stabilization wait time, taking into account both the shutter speed and zoom information. That's what I do.

In FIG. 15, 161 indicates a predetermined time i (
55. ......) predetermined time setting section for setting 1
A comparison circuit 62 compares the timer time t from the timer 111 with the predetermined time 1, and outputs an "H" signal while the relationship is t x i.

Next, the operation will be explained using the flowchart shown in FIG.

``Step 9o1'' First, the photographer sets the anti-shake switch l.
Wait for the 5SW to be turned on, and then proceed to step 902.

"Step 902" Since the timer switch TIMESW is also turned on in synchronization with the anti-vibration switch l5SW, the timer 111 is activated.

“Step 903” Here, the zoom information setting section 151
A comparison is made between i and the timer time t at a predetermined time set according to the zoom information and shutter speed set by the shutter speed setting section 141 and the zoom information set by the shutter speed setting section 141, and as long as the result is in the relationship t x ci, the comparison is not performed. From vessel 162 “H”
” signal is output, and the process advances to step 904.

On the other hand, if the relationship t>t i, that is, if the anti-vibration output is stable, this operation is ended without displaying the anti-vibration state and prohibiting the release.

"Step 9o4" The trigger means 104 is activated because the "H" signal is input from the comparator 162, and a trigger signal is output from the trigger means 104 to the anti-vibration state display section 105, and the process proceeds to step 905.

"Step 905" Since a trigger signal is inputted from the trigger means 104, the image stabilization state display section 105 lights up, and a state in which photography is not possible is displayed to the photographer.

"Step 906" Since the trigger signal is also input from the trigger means 104 to the release lock means 144,
Here, the release operation is prohibited by the means 144.

With this configuration, for example, the shutter speed is r1/60mmJ and the zoom information is r50mm.
In the case of J, the camera shake is quite small, so the predetermined time setting section 1
61, the predetermined time i is set to an extremely short time,
- During actual regular use (about 1/60mm, 50mm), there is almost no waiting time and you will not be aware that the anti-vibration mechanism is installed.

According to each of the above embodiments, the anti-vibration output (camera shake detection output)
Since the camera is configured so that the photographer can recognize the stable state of the camera by lighting or flashing, or even by making a sound, problems such as failures in shooting and missed photo opportunities are reduced. For locking configurations,
It is possible to eliminate mistakes in shooting.

In addition, with a configuration in which i is variable for a predetermined period of time depending on the set shutter speed and zoom information, during regular use (1760mm, 50mm, etc.), you will not be aware that the anti-vibration system is installed ( It is now possible to operate the camera immediately (without waiting time).

(Modified example) In this example, an angular velocity meter is used as an example of a device that requires time for the vibration isolation output to stabilize, but it is not limited to thermal theory. It is also applicable to cameras having an anti-vibration system using a sensor (for example, a sensor using an inertial coma as disclosed in Japanese Patent Application No. 1-296106).

(Effects of the Invention) As explained above, according to the present invention, there is provided a detection means for detecting the stability of the vibration isolation output of the vibration detection means, and a notification means for notifying the stability state detected by the detection means. Since the photographer is informed of the stability state of the image stabilization output, it is possible to prevent failures in photographing or missing photo opportunities.
