Abstract

PROBLEM TO BE SOLVED: To suppress the consumption of a power source and to continuously and smoothly control a shake correction control action by stopping the action of a shake correction mechanism when at least one power consumption source is actuated. SOLUTION: By a microcomputer for a shake correction control action 3, the driving of a shake correction driving part is controlled based on the output of a microcomputer for a body 25 in a body device 2 and the positional information of an optical system from an X encoder 5, a Y encoder 9, a distance encoder 15 and a zoom encoder 22. When a film feeding motor 30 is actuated, the action of the shake correction mechanism is stopped. The actuating time of the power consumption source means one or both of the actuating time of the motor 30 and the driving time of the lowering of a shutter mirror. By starting the shake correction control action again when the actuating time is finished, the power source voltage is prevented from being dropped in advance without adversely affecting the shake correction control action.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image pickup apparatus having a shake correction mechanism.

[0002]

2. Description of the Related Art Conventionally, in a photographing device such as a camera, A
The F mechanism has become common, and in recent years, it has been proposed to add a shake correction mechanism that further corrects camera shake to such a photographing device.

The shake correction mechanism detects the angle variation of the optical axis due to camera shake and the like, and shifts the shake correction mechanism based on the detection result to correct the shake in the photographed image. As a device, JP-A-2-
In Japanese Patent No. 66535, an example in which a shake correction mechanism is added to a single lens optical system, and in Japanese Patent Laid-Open No. 2-183217, image shake is corrected by shifting a part of a photographing optical system of an internal focusing type telephoto lens. Examples of doing so are known.

However, in a normal case, since the shake correction mechanism is driven by the power supply battery built into the camera, another sequence (for example, strobe charging or film feeding motor drive) is performed at the drive timing of the shake correction mechanism. If so, the shake correction mechanism is a relatively large power consumption source, so the power supply battery will be overloaded, and it will not be possible to supply sufficient power to the shake correction mechanism and other power consumption sources. This causes the power supply voltage to drop and the camera to stop functioning.

Therefore, in Japanese Patent Laid-Open No. 4-113338, the voltage state of the power source battery is detected, and the power supply to the shake correction mechanism or the photographing preparation operation is performed based on the detected value, for example, 50 during normal driving. Inventions that are limited to about 10% have been proposed.

[0006]

SUMMARY OF THE INVENTION However, Japanese Patent Application Laid-Open No.
The invention proposed by Japanese Patent No. 13338 has the problems listed below.

(1) Although the blur correction control is restricted except when the film is exposed, it does not affect the blur of the photographed image. However, when the blur correction control is restricted during the film exposure, the image is captured. It directly affects the blurring of photographs. In the invention proposed by Japanese Patent Application Laid-Open No. 4-113338, the blur correction control is restricted depending on the voltage state of the power supply battery even when the film is exposed, so that the photographed image is blurred.

(2) With the voltage of the power supply battery lowered,
When a large current is instantly consumed, a sharp drop in voltage occurs in accordance with the amount of voltage drop calculated as the product of the internal resistance of the power supply battery and the current. In the invention proposed by Japanese Patent Laid-Open No. 4-113338, since the voltage drop of the power supply battery actually occurs and the value is detected to limit the shake correction control, the voltage drop cannot be prevented in advance. However, it is impossible to eliminate the possibility of control malfunction or control abnormality due to a sudden drop in the voltage applied to the CPU that performs various controls of the imaging apparatus.

(3) In the invention proposed by Japanese Patent Laid-Open No. 4-113338, the shake correction control is limited after the voltage drop of the power source battery actually occurs, so that the life of the battery is shortened and the frequency of battery replacement is reduced. Will increase. for that reason,
It is conceivable that blur correction control may not be normally executed during actual shooting.

According to a second aspect of the present invention, in the image pickup apparatus including the shake correction mechanism according to the first aspect, after the control device stops or suppresses the operation of the shake correction mechanism,
When the power consumption sources are all stopped, the operation of the shake correction mechanism is restored.

[0012] The invention of claim 3 is claim 1 or claim 2.
In a photographing device equipped with the blur correction mechanism described in
The time is one or both of the operation time of the film feeding motor and the down drive time of the shutter mirror.

That is, the operation timing of the film feeding motor and the down drive timing of the shutter mirror are both
It is a time when it is not necessary to drive the shake correction mechanism and a time when power consumption is large. If the shake correction mechanism is stopped only at this time, the power consumption can be suppressed without impairing the shake correction effect. Further, since a complicated device such as a device for detecting power consumption is not required, it is possible to reduce the manufacturing cost.

According to a fourth aspect of the present invention, the photographic optical system and the blur of the optical axis of the photographic optical system are detected, and a part or all of the photographic optical system and the photographic screen are made relative to each other based on the detected blur amount. A shake correction mechanism for moving manually and at least one power consumption source that operates independently or in relation to each other, and a film if the shake correction mechanism is operable. It is characterized by comprising a control device which does not drive two or more of the power consumption sources at the same time after completion of the exposure.

According to a fifth aspect of the present invention, in the image pickup apparatus including the shake correction mechanism according to the fourth aspect, the power consumption source is a drive motor.

According to a sixth aspect of the present invention, in the image pickup apparatus having the shake correction mechanism according to the fifth aspect, the two or more driving motors that are not driven simultaneously are film feeding motors for film winding and rewinding. And a sequence control motor for driving other mechanical members.

According to a seventh aspect of the present invention, in the image pickup apparatus including the shake correction mechanism according to the sixth aspect, the sequence control motor for driving the other mechanical members is a mirror up and mirror down drive motor or a shutter curtain. It is characterized by including a traveling motor.

FIG. 6 is a graph showing an example of the relationship between the photographing timing of the camera and the current consumption of the film feeding motor and the sequence motor. In the graph shown in FIG. 6, when the mirror-up is started at time t ₁ , a large current suddenly flows into the sequence motor, the current value gradually decreases, and at time t ₂ which is the start time of the motor brake section. A large current flows in the opposite direction,
A weak current flows at time t ₃ , which is the end of the motor brake section, and the current value becomes 0 toward time t ₅ .

Subsequently, at time t ₅ , the mirror down is started, a large current flows through the sequence motor, and the sequence motor is temporarily reduced over time t ₆ . A substantially constant value is maintained from time t ₆ to time t ₉ , and at time t ₉ , the motor brake acts and a large current flows through the sequence motor.
_{At 10} , mirror down ends.

That is, a large current flows through the sequence motor immediately after the start of the mirror up, during the motor brake corresponding thereto, at the start of the mirror down and during the corresponding motor brake, but immediately after the start of the mirror up and Corresponding to this, during motor braking, it is immediately before exposure, and in the present invention, suppressing or stopping the operation of the shake correction mechanism may adversely affect the operation of the shake correction mechanism during exposure, which is not desirable.

If the shake correction mode is on, the process proceeds to step S712. If the shake correction mode is not on, the power consumption is low, so the process proceeds to step S715, and the mirror down and mechanical member drive control and the film feeding control are performed at the same time.

FIG. 8 is a time chart of an example of control in S714. As shown in the figure, after the release switch is turned on, mirror up is executed,
Mirror down, mechanical charge, and film feeding are performed, but in this case, since the shake correction mechanism that consumes a large amount of power is in an operating state, in order to suppress a sharp and drastic decrease in power, mirror down, mechanical charge control, etc. After the control of the sequence control motor is completed, the film feeding control is performed.

At S715, at the same time as the control of the sequence control motor such as mirror down and mechanical charge control,
Performs film feed control. FIG. 9 is a time chart of an example of control in S715. As shown in the figure,
In this case, since the shake correction mechanism that consumes a large amount of power is not in the operating state, the film feeding control is performed at the same time as the sequence control motor control such as mirror down and mechanical charge control.
