Further, the camera shake amount is detected by the angular velocity sensor, and the output of the angular velocity sensor is minute.

Next, the configuration of each part of the blur correction camera of this embodiment will be described in more detail. 2 and 3 are sectional views showing the blur correction optical system of the present embodiment. The shake correction optical system 54 is held by the shake correction optical system barrel 2, and the shake correction optical system barrel 2 is driven by an electromagnetic actuator 61. The actuator 61 is composed of the coil 6, the magnet 7, and the yokes 9 and 10, and two sets are arranged in directions orthogonal to each other.
The structure is such that a force is generated in each of the axial direction and the Y-axis direction.

FIG. 3B shows a movable state. Since FIG. 3 is a sectional view, only two flexible support rods 3a and 3b are visible.

Blur detection unit, B.
Position detector, C.I. Blur correction controller, D.I. It is roughly classified into a shake correction drive unit.

(Blur Detection Section) FIG. 4 is a perspective view showing the blur detection section according to the present embodiment. Shake detection element 13, 1

The release button 15 is a button for taking a picture with the camera.

FIG. 5 is a circuit block diagram showing the blur detection unit according to this embodiment. The blur detection elements 13 and 14 are
It is an angular velocity sensor that detects the angular velocity generated in the camera,
For example, a vibrating gyro that uses the principle of converting the Coriolis force generated by rotation into an electric signal using a piezoelectric element or the like is used. The LP filter 22 is a third-order active high frequency cut filter for removing high frequency noise from the outputs of the shake detection elements 13 and 14, and removes the influence of the resonance frequency of the shake detection elements 13 and 14 themselves. The HP filter 23 includes the blur detection element 1
A primary passive low-frequency cut filter whose main purpose is to remove low-frequency drift components on the surfaces 3 and 14.

The blur detection circuit initialization signal is a signal for initializing the blur detection circuit, and turns on / off the voltage of the output side terminal of the capacitor forming the HP filter 23 by turning on / off the analog SW (not shown). Is a signal which is controlled by and initializes the output of the shake detection circuit. The timing of this initialization is controlled by the blur correction CPU 20 based on the data that stores the time corresponding to the rising characteristics of the blur detection elements 13 and 14.

The gain section 24 is a voltage amplifying section for multiplying the output of the HP filter 22 by a predetermined gain and outputting it to the shake correction MCU 20. The reference voltage generation circuit 25 is a circuit that generates a reference voltage for operating the shake detection elements 13 and 14 and each circuit, and is configured to suppress voltage fluctuations by an independent DC / DC converter or the like.

(Position Detection Unit) FIG. 6 is a perspective view showing the position detection unit according to the present embodiment. The position detection element 56 is
An element that monitors the movement of the image stabilization optical system 54,
It is installed separately in the X-axis direction and the Y-axis direction. The position detecting element 56 is a PSD (Position Sensit).
It is composed of an iv device 5, an slit 4, and an infrared light emitting element (IRED) 8. PSD5a,
Reference numeral 5b denotes an IRED 8 whose total length of the detecting portion will be described later, a positional relationship between the slits 4, a slit width, and a shake correction optical system 54.
Is determined from the movable range of. The slits 4a and 4b are attached to the shake correction optical system barrel 2, and are made of a material whose surface reflectance is suppressed to be low. The slit 4a for detecting the X-axis direction has a long hole in the Y-axis direction. The slit 4b for detecting the Y-axis direction has a long hole in the X-axis direction. IRED8a, 8b
Are attached to the circular printed circuit board 17.

FIG. 7 is a schematic diagram showing the position detecting element of the position detecting portion according to this embodiment. The light projected from the IRED 8a passes through the slit 4a attached to the shake correction optical system barrel 2 and enters the one-dimensional PSD 5a for position detection. Due to the movement of the slit 4a, that is, the movement of the shake correction optical system 54, the incident position of the spot light passing through the slit 4a moves on the light receiving element surface of the one-dimensional PSD 5a, and the bipolar terminal is operated according to the known principle of the PSD 5a. The value of the current flowing from changes depending on the position where the current enters.

FIG. 8 is a circuit block diagram showing an arithmetic circuit for calculating the position of the light incident from the slit from the output current of the one-dimensional PSD of the position detector according to this embodiment. The PSD 5 is supplied with the reverse bias voltage from the reverse bias voltage circuit 65, and the photocurrent determined by the slit position is divided into I1 and I2 and flows out. In this case,
The current increases as the slit approaches the current extraction electrode. This state is as shown in FIG.

The photocurrents I1 and I2 are converted into voltages by the current-voltage conversion circuit 68. Output voltage V
1 and V2 are R1 × I1 and R2 × I2, respectively. Further, these outputs are output to the voltage amplifier circuits 67a and 6a.
It is amplified by 7b, and V1 and V2 are multiplied by α.

These outputs are input to the calculation unit, that is, the A / D conversion input terminal of the blur correction MPU 20, and converted into a signal V0 indicating the position of the slit. V0 outputs the position signal X of the light incident from the slit 4 on the one-dimensional PSD 5 as the voltage V0 by the arithmetic expression of V1 and V2 shown in FIG. This output V0 is input to the A / D conversion port of the microcomputer, and the incident position X is obtained by the equation (1) in FIG. (I1-I2) / (I1 + I2) = 2X / L-1 (1)

Further, this calculation may be performed by the following method without using the shake correction MPU. For example, either changing the gain of the voltage amplifier circuit or changing the photocurrent of the IRED so that the voltage of α · V1 + α · V2 becomes 1 (V) with respect to the potential of the reference voltage VREF. Using such control, α · V2-α · V1 is output. When the slit is at the end of the I1 side electrode, theoretically, most of the photocurrent flows to the I1 side terminal, and no photocurrent of the I2 side flows. Therefore, the following condition is established, and the voltage V0 indicating the position X is relative to the potential of the reference voltage VREF.
It outputs -1 (V).

Α · V1 + α · V2 = 1 (V) V2 = 0 V0 = (α · V2-α · V1) / (α · V1 + α · V2) =-1 (V)

On the other hand, when the slit is at the end of the I2 side electrode, V1 = 0 (V), and the voltage V0 indicating the position X becomes +1 (V) as shown below. α ・ V1 + α ・ V2 = 1 (V) V1 = 0 V0 = (α ・ V2-α ・ V1) / (α ・ V1 + α ・ V2) = + 1 (V)

FIG. 10 is a diagram showing the relationship between the position information of the light incident from the slit on the PSD and the output voltage of the position information. The X-axis represents the incident position of light that strikes the PSD 5, and the Y-axis represents the output voltage V0 corresponding to the incident position X on the PSD. As can be seen from FIG. 10, the position of the slit light on the light receiving surface of the PSD 5 and the output voltage value are in a proportional relationship, and the position of the slit 4, that is, the blur, can be detected by monitoring the output voltage value from the calculation unit. Correction optical system 54
The position of can be detected.

(Blur Correction Drive Unit) Next, referring to FIG.
A method of supporting the shake correction optical system lens barrel will be described. The shake correction optical system barrel portion 2 includes an elastic support member 3 having high conductivity.
Supports cantileverly. Elastic support member 3
Can be a copper alloy such as beryllium copper or phosphor bronze, or an elastic material other than that subjected to surface treatment with high conductivity such as gold plating. One side of the elastic support member 3 is inserted into the shake correction optical system barrel section 2, and the other side is fixed to the annular printed circuit board 17 by soldering or the like.

The blur correction optical system lens barrel 2 has
A drive range limiting member (not shown) is provided. The drive range limiting member has a structure that limits the movement of the shake correcting optical system 54 at a position close to the coil that drives the optical system 54. Since the shake correction optical system barrel 2 has a structure in which it is difficult to generate a moment when hitting its limiting member, there is no risk of adversely affecting the elastic support member 3 that supports the shake correction optical system 54.

(Blur Correction Control Unit) Next, the calculation unit of the appropriate correction amount of the blur correction lens based on the integral calculation result of the angular velocity will be described. FIG. 11 is a diagram for explaining the operation of the blur correction camera of this embodiment. In this camera, when vibration of a sine wave occurs, the output of the shake detection circuit is as shown in the figure. At t0, the release button of the camera is half-pressed, and the half-press switch 27 is turned on, and at the same time, the step-up switching operation of the DC / DC converter is started and the power source of the shake detection circuit is turned on.

The output of the shake detection element has a lot of noise components immediately after rising, and it takes time to stabilize.
Here, in the case of detecting the zero angular velocity, if the output with the irregular time is detected, the reference zero angular velocity cannot be accurately detected. Therefore, the blur detection output initialization control signal output from the blur correction MPU 20. As a result, the analog SW of the shake detection circuit is turned on for a predetermined time, the angular velocity output is forcibly set to zero, and the output of the amplifier circuit is prevented from greatly shaking. The ON time of the analog SW after the power of the shake detection element is turned on is set to 50 ms or less so that the release time lag does not become long.

After t2, an output obtained by operating the shake detection circuit is obtained. However, due to the circuit configuration, the output of the shake detection unit is irrespective of the angular velocity, the angular velocity sensor, or
The output is an initial voltage that is a predetermined voltage determined by the circuit condition of the shake detection unit, and it is difficult to accurately detect zero angular velocity. A detailed explanation is omitted here,
The analysis of the angular velocity output waveform is performed by the shake correction MPU 20, and the analog switch is turned on again at the timing t3 when the angular velocity is predicted to be zero, and the angular velocity output is corrected to zero. Here, the output of the vibration gyro is amplified as the reference potential of the angular velocity output, and the output is shake compensation MPU.
It is input to the A / D conversion port of 20 and the integral calculation of the angular velocity is performed. As a result, the output of the shake detection unit is corrected to an amplitude such that the approximate angular velocity becomes a predetermined voltage at the timing of zero. Here, the integral calculation is a digital calculation by the blurring correction MPU 20 in this embodiment, and the blurring angle θc is calculated by integrating the calculated angular velocities ω.

The blur angular velocity ω is theoretically converted into the blur angle θc by the following equation. θc = ∫ωdt [Unit: °] = Σω [Integrates ω at predetermined time intervals (during digital control)] Next, the blur correction MPU 20 periodically repeats the blur amount calculation from the blur angle θc, and releases the release button. Wait for the full press operation of.

Next, the input voltage of the shake correction drive unit 59 and V
The CM applied voltage will be described. Output Vout from blur correction MCU 20 and internal reference voltage Vref (= 2.0V)
Is applied to the VCM (voice coil motor). For example, in the case of the drive voltage of the Y-axis voice coil motor, when the voltage from the MPU 20 to the drive unit 59 is higher than the reference voltage, a current is caused to flow in the direction to drive the shake correction optical system 54 upward, while the reference potential is increased. When a lower voltage is transmitted, the drive circuit is such that a current flows in the opposite direction to the former. The value of the drive voltage and the current flowing through the voice coil motor are in a substantially proportional relationship, and the shake correction optical system 54 also moves the drive amount in proportion to this.

FIG. 12 is a diagram showing the relationship between the voltage applied to the voice coil motor and the position of the correction lens. The horizontal axis is MP
The voltage is a voltage transmitted from U20 to the drive unit 59, and the output is a voltage applied to the voice coil motor. That is, the polarity of the applied voltage on the vertical axis is inverted with the input voltage on the horizontal axis at the reference potential 2 (V), and the current flowing to the coil is inverted. Such a mechanism is provided independently for the X axis and the Y axis.

Next, when the release button is pressed deeply at the timing of t4, the release switch 28 is turned on and the photographing operation is started. The shake correction apparatus controls the drive of the shake correction optical system 54 from this time to t11 when the exposure ends. This control is based on the amount of camera shake, and the amount of drive of the camera shake correction optical system 54 of the camera shake correction device is set so as to suppress the camera shake on the film surface.
In accordance with the output Vout from, the blur correction drive unit 19 drives the VCM so that the blur correction lens 54 shifts in the plane direction orthogonal to the optical axis.

At t4, the focusing lens is driven and the exposure operation is simultaneously performed by the shutter device. In this embodiment, the same stepping motor is used to drive them. The stepping motor drive signals 1 and 2 are known two-phase excitation type motors and are controlled by digital signals. This signal generates a control signal from the blur correction MPU 20 and transmits it to the motor drive circuit shown in FIG.

FIG. 13 is a circuit diagram showing the motor drive circuit according to the present embodiment. The motor drive circuit includes a constant voltage regulator 31 for constantly supplying a constant voltage to the motor.
And a transistor 32, a motor drive IC 30 for driving the motor driving transistors 33 to 40 that are switched by a digital signal from the shake correction MPU 51, and stepping motors 49 and 50. The stepping motor drive transistor is composed of two sets of bridge circuits,
The currents flowing through the two-phase stepping motors are alternately inverted. Moreover, the reason why the voltage regulator is provided in the driving power source of the stepping motor is to stabilize the voltage and thereby reliably control the driving control to stabilize the driving and exposure accuracy of the focusing lens.

Next, stepping motor drive signals 1 and 2 and stepping motor drive control will be described. In FIG. 10, at the timing immediately before t4, the stepping motor drive signals 1 and 2 are both in phase H, and the stepping motor is in a stable state. At this time, the stepping motor driving transistors 33 and 3
Since 7, 35, and 39 are turned on, current flows in the stepping motor coils 49 and 50 in the X direction. Then, the phases of the stepping motors 49 and 50 are alternately changed from the timing of t4. First, the phase of the stepping motor drive signal 1 changes to L. At this time, the transistors 33 and 37 are cut off, and the transistors 34 and 38 are turned on. Then, the current of the stepping motor coil 49 is inverted and flows in the Y direction. Further, the focusing lens 55 is extended for one step.

Next, the phase of the stepping motor drive signal 2 changes from H to L. At this time, the transistor 3
5 and 39 are cut off and transistors 36 and 40 are turned on. Then, the current of the stepping motor coil 50 is reversed and flows in the Y direction. Further, the focusing lens 55 is further extended by one step, and the lens extension for a total of two steps is completed.

In this way, the focusing lens 55 is extended step by step every time the direction in which the drive current of the one-side stepping motor 49 or 50 flows is alternately changed.

Furthermore, the phase of the stepping motor drive signal 1 changes from L to H. At this time, the transistor 3
4 and 38 are cut off, and the transistors 33 and 37 are turned on. Then, the current of the stepping motor coil 49 is inverted and flows in the X direction. Further, the focusing lens 55 further extends one step.
Then, at the timing of t4 ', the energization of the AF magnet (not shown) is cut off, so that the amount of extension of the focusing lens 55 is determined here. Further, a driving ring (not shown) for driving the focusing lens is driven until t5, and energization control of the stepping motor is continued for the exposure preparation process of the shutter. next,
At t6, the exposure operation of the shutter starts.

The shutter opening driving operation is performed from t6 to t9, and the closing operation is performed from t10 to t11.
Further, the operation from t12 to t13 is a stepping motor operation for returning the focusing lens to the initial position.
