Abstract

PURPOSE:To prevent a jiggle correction lens from being positioned near the end of a correction range and to surely prevent jiggle from occurring at a releasing time by including the specified jiggle correction lens, a specified jiggle correction lens position detection means and a specified display means. CONSTITUTION:This camera is provided with the jiggle correction lens 17 which can be moved in an in-plane which is vertical to an optical axis, the blurring correction lens position detection means 15 which detects the eccentric amount of the lens 17 from the optical axis and the display means 201 which displays a direction that a camera is jiggled so that the eccentric amount becomes zero. Then, a jiggle preventing action is started under a photographing standby state before releasing (under the state that a shutter button is half depressed and a half-depressing switch is turned on, for example). That means, the lens 17 is moved so as to correct the jiggle and the center thereof is decentered from the center of the optical axis. Besides, since the lens 17 is provided with the largest correction range with respect to top and bottom and left and right when it is positioned at the center of a movable stroke at the releasing time, the jiggle can be sufficiently corrected.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-shake camera.

[0002]

As a conventional technique, for example, before taking a picture,
There has been a display in which the camera shake is displayed together with the allowable range of the camera shake amount by a bar graph or the like proportional to the camera shake amount, and after the shooting, how much the shooting is blurred (Japanese Patent Laid-Open No. 126251/1990). ..

When the amount of blur exceeds the allowable range,
For example, by blinking a bar graph or generating a sound,
Some have warned the photographer of camera shake (Japanese Patent Laid-Open No. 2-1.
26250).

On the other hand, the camera has a shake detection sensor and a shake correction lens, and moves the shake correction lens on a plane perpendicular to the optical axis based on the amount of shake detected by the shake detection sensor to prevent the shake. Cameras are also known.
In the blur correction lens, a correction range is determined by a mechanical or electric stopper means at a position where the optical image quality is not deteriorated or slightly deteriorated.

[0005]

However, in the above-mentioned conventional technique, only the amount of blurring is displayed before shooting, and it is unclear in which direction the center of blurring has moved. .. When the center of blurring moves, the camera shake correction lens may reach the end of the correction range. That is,
If the center of the blur is at the edge of the correction range when the shutter is released, the camera shake correction lens that has moved in the blur correction direction hits the stopper and cannot be fully corrected. However, the photos taken will be blurred.

The object of the present invention is to solve the above-mentioned problems,
An object of the present invention is to provide a camera-shake preventing camera capable of reliably preventing camera shake by preventing the camera shake correction lens from being near the end of the correction range at the time of release.

[0007]

In order to solve the above-mentioned problems, a camera-shake preventing camera according to the present invention comprises a camera-shake correction lens 17 that is movable in a plane perpendicular to an optical axis and a camera-shake correction lens. Camera shake correction lens position detection means 15b to 15h for detecting the amount of eccentricity from the optical axis, and display means 20 for displaying the direction in which the camera is swung so that the amount of eccentricity becomes zero.
1 and 101 are included.

Further, from the optical axis of the camera shake correction lens 17, which is movable in a plane perpendicular to the optical axis, the operation range limiting means 15a which limits the operation range of the camera shake correction lens, and the optical axis of the camera shake correction lens. When the hand shake correction lens position detecting means 15b to 15h for detecting the amount of eccentricity of the hand shake correction lens and the hand shake correction lens approach the working range limiting means, as compared with when the hand shaking correction lens is far from the working range limiting means, It is possible to adopt a configuration including display means 201, 105 for displaying a large direction in which the camera is shaken so that the amount of eccentricity of the blur correction lens becomes zero.

In these cases, the camera shake correction lens position detecting means 15b to 15h detect the neutral position detecting means 15b to 15f for detecting the neutral position of the camera shake correcting lens.
And movement detection means 15g and 15h for detecting the movement amount and movement direction of the camera shake correction lens.

On the other hand, the camera-shake preventing camera according to the present invention is
Image stabilization lens 17 that can move in a plane perpendicular to the optical axis
And an operation range limiting means 15a for limiting the operation range of the camera shake correction lens, and when the camera shake correction lens comes into contact with the operation range limiter, the camera shake correction lens is moved to a setting position of the operation range. Setting position moving means 1
3 to 13i may be included.

[0011]

In the present invention, the camera shake prevention operation is started in a shooting standby state before release (for example, in a state where the shutter button is half-pressed and the half-press switch is turned on). That is, the camera shake correction lens moves so as to correct camera shake, and its center is decentered from the optical axis center. This camera shake correction lens has the largest correction range vertically and horizontally when it is in the center of the movable stroke during release.
The blur can be corrected sufficiently.

The display means of the present invention displays in which direction the camera is moved, the eccentricity of the camera shake correction lens becomes zero, and the camera shake correction stroke becomes maximum. As a display method, for example, a bar graph or the like can be displayed in the peripheral portion of the screen in the finder.

As the eccentricity of the camera shake correction lens increases,
When approaching the operating range limiting means (stopper), for example, a large long arrow is displayed to inform the photographer that the camera shake correction lens is near the operating range limiting means. In other words, the photographer is urged that the camera should be shaken in a large display direction of the display means to make the amount of eccentricity of the camera shake correction lens zero.

By changing the direction of the camera according to the instruction of the display means, the camera shake correction lens is always in the vicinity of the center of its movable stroke and the eccentricity is close to zero. Therefore, the blur correction range becomes the widest, and the probability that the correction lens comes into contact with the operation range limiting means during the exposure of the camera and the blur correction cannot be performed is reduced.

On the other hand, when the camera shake correction lens comes into contact with the operation range limiting means, the set position moving means moves the camera shake correction lens to the set position of the operation range, for example, the neutral position, so that the vicinity of the center of the movable stroke. Therefore, the eccentricity is set back to zero.

7 is for limiting the operation on the left side of the camera shake correction lens 7, and the operation of the camera shake correction lens 17 on the left side in the X direction in FIG. 2 is brought into contact with the reference surface 18c for detecting the position of the camera shake correction lens 17. It is a limit. Stopper 1

The stopper 15'a is the camera shake correction lens 1
7 for limiting the upper operation of the camera shake correction lens 17, and by contacting the reference surface 18d for detecting the position of the camera shake correction lens 17, the operation of the camera shake correction lens 17 on the upper side in the Y direction in FIG. It is a limit. Stopper 13
g is the bottom surface of the square hole 13h, and is a protrusion 1 having a square cross section.
By contacting the end surface 18e of 8b, the operation of the camera shake correction lens 17 on the lower side in the Y direction in FIG. 2 is restricted. The stoppers 15a, 15'a have a hole in the center for passing the brushes 15f, 15'f.

(Explanation of camera shake correction lens position detection means)
The brush 15f is for detecting that the eccentricity of the camera shake correction lens 17 in the X direction is zero, the base side is fixed to a part of the lens frame 18 (the reference surface 18c side), and the tip side is It is divided into a contact portion 15b and a contact portion 15c. The insulating substrate 15i has conductor portions 15d, 1 on its surface.
5e is provided. The conductor A is connected to the conductor 15e, and the conductor B is connected to the conductor 15e.

In FIG. 2, when the eccentricity of the camera shake correction lens 17 is on the left side of the optical axis, the contact portion 15b comes into contact with the conductor portion 15d, and the conductors A and B are brought into conduction. When the eccentricity of the camera shake correction lens 17 is on the right side of the optical axis, the contact portion 15b comes into contact with the surface of the insulating substrate 15i, and the conduction between the conductor A and the conductor B is cut off. When the contact portion 15b is switched from conducting to non-conducting between the conducting wires A and B or when conducting is switched from non-conducting to conducting, it is possible to detect that the eccentricity of the camera shake correction lens 17 in the X direction is zero. In FIG. 2, the contact portion 1 is provided at the right end of the conductor portion 15d.
The position where 5b contacts is the X-axis direction, and the image stabilization lens 17
When the eccentricity of is zero. With the above configuration, it is possible to detect whether or not the eccentricity of the camera shake correction lens 17 in the X direction is zero (neutral position detection means).

The encoder plate 15g is fixed to a shaft mounted coaxially with the output shaft of the motor 13. Also,
Two photo couplers 15h are provided around the encoder plate 15g. The encoder plate 15g and the photocoupler 15h allow the photointerrupter (15g, 15g
h) is configured. With the rotation of the motor 13, a pulse is generated from the photo interrupter (15g, 15h). Two photocouplers 15h are provided around the encoder plate 15g, and the forward and reverse rotations of the motor 13 can be recognized from the outputs of the two photocouplers 15h. Therefore, by counting this pulse, the movement amount and movement direction of the camera shake correction lens 17 can be known (movement detection means).

The contact portion 15b of the brush 15f shows the time when the eccentricity of the camera shake correction lens 17 in the X direction is zero, and the pulse from the photointerrupter (15g, 15h) shows the amount of displacement from that point. A, B

From 15e, 15f, 15g, and 15h, the camera shake correction lens position detecting means 15 in the X direction shown in FIG. In addition, the camera shake correction lens position detection means 1 in the Y direction
5'is also similar to the case of the X direction, the conductive wires A ', B', the members 15'b, 15'c, 15'd, 15'e, 15 '.
It is composed of f, 15'g, 15'h and the like.

In this embodiment, the camera shake correction lens 17
Is, for example, 1.5 mm to the left from the neutral position,
1.5 mm to the right, 1.5 mm up, 1.5 m down
Eccentricity is possible by m. Therefore, when the camera shake correction lens 17 is in the neutral position, the stopper 15
Distance between a and reference surface 18c, stopper 13'g and end surface 18
The distance of f, the distance between the stopper 15′a and the reference surface 18d, and the distance between the stopper 13g and the end surface 18e are 1.5 m, respectively.
It becomes m. If it is eccentric by this amount, the above-mentioned stopper 15
a, 15'a or the stoppers 13g, 13'g. As described above, during exposure, the camera shake correction lens frame 18 is moved to the stoppers 15a, 15'a or the stoppers 13g,
If it comes in contact with 13'g, the image stabilization lens 17
Will not move anymore, and it will not function as an anti-shake function, and the pictures taken will be blurred. The present invention has been made to minimize the probability of such a failure.

(Explanation of Main Flow) FIG. 3 is a flow chart showing the main operation of the anti-shake camera according to the embodiment, FIG. 4 is a flow chart showing a subroutine of display processing, and FIG. 5 is a flow chart showing a subroutine of processing during exposure. is there. The flow of FIG. 3 is the same as that of the CPU 201 or the shake control means 8 shown in FIG.
Controlled by 8 '. Here, only the X direction will be described. When the main switch (not shown) is turned on, the power of the camera is turned on and the flow starts (S1). When the photographer looks through the viewfinder to compose the image, presses the shutter button halfway, and the halfway switch SW1 is turned on (S
3), the AF device, the camera shake prevention device, the display device, etc. start operating, and the preparation for photographing is started.

Next, in step S5, display processing is performed to indicate in which direction the camera should be shaken to bring the camera shake correction lens 17 to the neutral position of the optical axis. This step S5 is
When the full-press switch SW2, which will be described in detail in FIG. 4, is turned on (S6), the shutter is opened and exposure is started (S7).

Next, in step S9, it is detected by the camera shake correction lens position detection means 15 whether or not the camera shake correction lens 17 has come into contact with the stopper, and the result is displayed on the display section 35 around the finder for several seconds. .. This in-exposure process (S9) will be described in detail with reference to FIG. When the shutter is closed and the exposure is completed (S11), the film is wound up and the mechanical section is charged (S1).
3) One shooting operation is completed (S15).

(Explanation of Display Processing Subroutine) Next, the subroutine of the display processing (S5 of FIG. 3) will be described with reference to FIG. The flow below is for the CPU 20
1 or shake control means 8, 8 '. First,
In step S55, the position of the camera shake correction lens 17 is measured by the camera shake correction lens position detection means 15 for display. In the following description, with respect to the optical axis center 0 in FIG. 2, the left side of the X axis is positive and the right side is negative. Further, with respect to the optical axis center 0, the eccentricity is positive on the Y axis and negative on the lower side.

In this embodiment, the camera shake correction lens 17 has the stoppers 15a, 15'a, 13g, 13'g.
Approaching to the camera shake correction lens 17 and the stopper 15
a, 15'a, 13g, 13'g is less than 1/3 of the distance when the eccentricity of the camera shake correction lens 17 is zero, and when the distance is far, the distance is It means that the amount of eccentricity is larger than 1/3 of that when it is zero. However, 1/3 is not included.

Next, in step S57, the measured eccentricity of the camera shake correction lens 17 is changed from -0.5 mm to +.
If it is within the range of 0.5 mm, the process proceeds to step S63, and if it is not within the range, the process proceeds to step S59. In step S63, as shown in FIG. 6, the displays 101 and 101 'are displayed on the display section 35 around the finder, and then the process proceeds to step S71.

The displays 101 and 101 'in FIG. 6 show that if the camera is slightly swung to the left and slightly to the upper side, the correction optical system (camera shake correction lens 17) comes to the center of the optical axis. .. Further, the displays 101 and 101 'are shown by a short bar graph because the amount of eccentricity is slight. Note that the direction in which the camera is shaken is determined by the CPU 201 in FIG. 1, and a signal is sent to the display driver 203,
This allows the display of the bar graphs around the screen 101, 10
1 ', etc. are lit up.

In step S59, the camera shake correction lens 1
It is determined whether the eccentric amount of 7 is in the range of -1 mm to +1 mm. Actually, in step S57, −
Since the discrimination in the range of 0.5 mm to +0.5 mm is performed, here, -1 mm to -0.5 mm or +0.
This means that it is determined whether or not the amount of eccentricity of the camera shake correction lens 17 is within the range of 5 mm to +1 mm. If the amount of eccentricity is within this range, the process proceeds to step S65, and if not, the process proceeds to step S61.

At step S65, as shown in FIG.
After the displays 103 and 103 'are displayed on the display unit 35 around the finder, the process proceeds to step S69. Display 10 of FIG.
Reference numerals 3 and 103 ′ show the shape of the tip of the bar graph that the center of the camera shake correction lens 17 comes to the center of the optical axis if the camera is swung slightly to the left and slightly to the upper side.

In step S61, the camera shake correction lens 1
It is determined whether the eccentric amount of 7 is between -1.5 mm and +1.5 mm. For this judgment, the eccentricity is -1.5m.
It is not included when m and +1.5 mm. Here again, in step S59, since the eccentricity amount is already discriminated from -1 mm to +1 mm, the eccentricity amount is actually -1.5 mm to -1 mm or +1 mm to +1.5 m.
It means that it is determined whether or not it is in m. If there is an eccentric amount in this range, the process proceeds to step S67, and if there is no eccentric amount in this range, the process proceeds to step S69. When the amount of eccentricity is in the range of S59, the distance between the stopper and the correction lens is 1/3 or less of that when the amount of eccentricity is zero.

At step S67, as shown in FIG.
After the displays 105 and 105 'are displayed on the display section 35 around the finder, the process proceeds to step S71. Display 10 of FIG.
Reference numerals 5 and 105 'show that the center of the camera shake correction lens 17 returns to the center of the optical axis when the camera is shaken largely to the left and shaken upward. If you shake the camera to the left and not to the top, the frame 18 of the image stabilization lens 17
Comes into contact with the stoppers 15a and 15a ', and the camera shake correction lens 17 moves toward the stoppers 15a and 15a'.
Image stabilization cannot be performed by moving the. In this case, the displays 105 and 10 as shown in FIG. 8 which are longer than the bar graphs as shown in FIGS.
Do 5 '. In order to strongly appeal to the visual sense of the photographer, the displays 105 and 105 'show the direction in which the camera is swung by bar graphs and arrows.

The feature of this embodiment is that, as described above, when the frame 18 of the camera shake correction lens 17 approaches the stopper, the display is enlarged non-linearly to strongly appeal to the visual sense of the photographer. As described above, apart from appealing to the visual sense of the photographer, a method of issuing a warning sound to appeal to the auditory sense of the photographer may be adopted, or both may be used together.

In step S61, the eccentric amount is -1.5 mm.
Alternatively, if it is determined to be +1.5 mm, the frame 18 of the camera shake correction lens 17 is in contact with the stopper, and camera shake correction in the contacting direction cannot be performed, so the process proceeds to step S69. In step S69, the camera shake correction lens 17 is returned to the neutral position. After displaying steps S63, S65, and S67, the flow proceeds to step S71.
Return to step S7.

In this embodiment, the decentering amount of the camera shake correction lens 17 and the bar length of the bar graph showing the amount of camera shake for returning the camera shake correction lens 17 to the optical axis center are shown in FIG. I changed it in stages. In FIG. 10, the bar length of the bar graph is suddenly increased at the position where the eccentricity shifts from -1.0 mm to -1.5 mm and the position where the eccentricity shifts from 1.0 mm to 1.5 mm, and The camera shake correction lens 17 is notified that it is approaching the stopper.

The eccentricity amount of the camera shake correction lens 17 and the bar length of the bar graph do not have to be stepwise as shown in FIG. 10, and linearly change as shown in FIG. You may do it. Even if it changes linearly, the straight line is bent at the position where the amount of eccentricity goes in the negative direction from -1.0 mm and the part where it becomes larger than 1.0 mm. Suddenly, the length of the bar graph is suddenly lengthened for the same amount of eccentricity change, so that the photographer is notified that the camera shake correction lens 17 is approaching the stopper. ..

(Explanation of In-Exposure Processing Subroutine) Next, the in-exposure processing subroutine of step S9 in FIG. 1 will be described in detail with reference to FIG. Even if the camera shake correction lens 17 is not in contact with the stopper before the exposure, if the camera shake correction lens 17 is in contact during the exposure, the camera shake correction in the contact direction cannot be performed, and the photographed image becomes blurred. .. Therefore, it is configured to detect whether or not the camera shake correction lens 17 contacts the stopper during exposure.

In FIG. 5, in step S91,
During exposure, the camera shake correction lens position detection means 15 detects whether the camera shake correction lens 17 has come into contact with the stopper. If not, the process proceeds to step S93.
If they are in contact, the process proceeds to step S97.

At step S93, as shown in FIG.
As a display 107, a circle mark is lit to inform the photographer that the camera shake correction lens 17 does not come into contact with the stopper during exposure and that the camera shake correction is normally performed. The display 107 is
It is kept on for a few seconds after shooting for confirmation. Step S
After the end of 93, the flow proceeds to step S95.

Next, in step S97, the display 107
The X mark is turned on (at the position indicated by the O mark in FIG. 9), and the camera shake correction lens 17 contacts the stopper during exposure to inform the photographer that normal camera shake correction has not been performed. .. Also in this case, the display 107 of the X mark remains lit for several seconds after the photographing is completed. The above ○ and × marks are
As in this embodiment, it is not necessarily the display section 35 around the finder, but may be the outer peripheral section of the camera. After the end of step S97, the flow is step S95.
Go to. This flow returns through step S95 and returns to step S11 in FIG.

The present invention is not limited to the embodiment described above, and various modifications can be made. For example, as the set position, the camera shake correction lens 17 has been described as an example in which it is returned to the neutral position, but it may be returned to the end portion on the opposite side.

[0056]

As described above in detail, according to the present invention, since the operation range limiting means (stopper) is provided for the movement of the camera shake correction lens, the camera shake correction is not performed until the image deteriorates. Therefore, clear pictures can be obtained. At this time, if you move the camera as shown, the camera shake correction lens will be at the correction stroke setting position (center or the opposite end), so the correction stroke will be large for camera shake in any direction. , The probability of getting a photo without camera shake is improved. Further, when the camera shake correction lens comes close to the operation range limiting means, the photographer is informed by a large display so that the user is not overlooked. Further, when the camera shake correction lens comes into contact with the operation range limiting means, it is returned to the set position, so that a large correction stroke can be obtained.
