Abstract

PROBLEM TO BE SOLVED: To enable a photographer to take intended photograph by deciding the driving or the stopping of a shake correction mechanism, based on the movement of the line of sight of the photographer and the detected value of the shake of an optical axis. SOLUTION: This photographing device is constituted of a shake detection part consisting of a shake correction head amplifier 13, a line-of-sight detection mechanism consisting of an illumination light source 29, a condensing lens 30, a photoelectric converter 31 and the like and the shake correction mechanism consisting of a microcomputer 3 for correcting shake, a shake correction driving part and the like. Then, the line-of-sight detection mechanism detecting the movement of the line-of-sight of the photographer is combined with the photographing device provided with the shake correction mechanism so as to judge whether vibration detected by the shake detection part is the shake or a panning action when the vibration is generated or immediately after it is generated. That means, when the vibration is generated in an almost identical direction to the moving direction of the line of sight after the line of sight is moved in certain direction, it is judged to be the panning action. Then, this result is applied for controlling the driving of the shake correction mechanism.

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, an AF mechanism has been generally used in a photographing device represented by a camera. In recent years, it has been proposed to add a shake correction mechanism for correcting camera shake to this image capturing apparatus.

This blur correction mechanism is incorporated in a photographing device to detect an angular variation of the optical axis due to camera shake or the like, and corrects a photographed image by this. For example, Japanese Patent Laid-Open No.
An example applied to a single-lens optical system is disclosed in Japanese Patent No. 66535, while a captured image is corrected by shifting a part of a photographing optical system of an internal focusing type telephoto lens in Japanese Patent Laid-Open No. 2-183217. Examples of doing so are known.

[0004]

However, in a conventional image pickup apparatus having a shake correction mechanism, when vibration is detected in the shake detection unit, the shake is corrected by assuming that all the vibration is due to camera shake. It was not distinguished whether the vibration detected by the detection unit was due to camera shake or an intentional pan operation (follow shot) by the photographer.

Therefore, even when the shake correction control should not be performed due to the pan operation by the photographer, the shake correction mechanism is moved in the direction opposite to the moving direction of the optical axis,
There was a problem that it was not possible to accurately capture the subject to be photographed.

It should be noted that it is possible to distinguish between hand shake and pan motion by utilizing the fact that the frequencies of vibrations of hand shake and pan motion are significantly different.
However, this means recognizes the camera shake or pan motion for the first time by measuring the frequency of this vibration after the vibration actually occurs, and at the time of recognition, the camera shake to be corrected has already converged. It has been closed and cannot be applied to blur correction control.

[0007]

SUMMARY OF THE INVENTION In view of the above problems, the present invention combines an image pickup apparatus having a shake correction mechanism with a line-of-sight detection mechanism for detecting the movement of the line of sight of a photographer, and the shake detection section detects the movement. At the time of or immediately after the occurrence of the vibration, it is judged whether the motion is a shake or a pan motion, in other words, when the line of sight moves in a certain direction and then the vibration occurs in substantially the same direction, it is a pan motion. Therefore, the result is applied to the drive control of the shake correction mechanism.

According to a first aspect of the present invention, there is provided a shake correction mechanism for relatively moving all or a part of the photographing optical system and a photographing screen based on a detection value of blurring of an optical axis in the photographing optical system, and a photographer. Line-of-sight detection mechanism for detecting movement of the line-of-sight of the camera, and a blur determining mechanism for driving or stopping the blur-correction mechanism based on the movement of the line-of-sight output by the line-of-sight detection mechanism and the detected value of the blur of the optical axis. And a correction control unit.

According to a second aspect of the present invention, in the image pickup apparatus including the blurring correction mechanism according to the first aspect, the blurring correction control unit causes the line of sight at a predetermined speed or more in a crossing direction with respect to the optical axis direction. After the movement of a predetermined amount or more, if the optical axis shake occurs in the same direction or substantially the same direction as the cross direction within a predetermined time from the time of this movement, the shake correction mechanism is stopped, or It is characterized in that the drive in the suppressed state is determined.

That is, the shake correction control microcomputer 3 compares the sensor output change amount obtained in S601 with a preset limit sensor change amount, and the sensor output change amount is a preset predetermined amount. If it is larger than that, it is determined that a large sensor output change has occurred, and the process proceeds to S603. On the other hand, when the sensor output change amount is smaller than or equal to the preset limit sensor change amount, it is determined that the sensor output large change has not occurred, and the process proceeds to S604.

[0056] In S609, the elapsed time T _dly of up to now from the line of sight very of time T _ct, is calculated by the difference between the line of sight very of time T _ct and the current time _{T now (T now -T ct)} ,

Proceed to 11. On the other hand, the line-of-sight large change time T _ct is the predetermined time T
If it is greater than or equal to _lim1 , the process proceeds to S608.

[0058] In S611, a predetermined period of time calculated line-of-sight very of time T _ct has been set in advance in S609 T
_It is determined whether it is larger than _lim2 . When the large line-of-sight change time T _ct is larger than the predetermined time T _lim2 , S6
Proceed to 12. On the other hand, the line-of-sight large change time T _ct is the predetermined time T
_When it is greater than or equal to _lim2 , the process proceeds to S608.

The predetermined time T _lim1 is set to a value smaller than the predetermined time T _lim2 . In S612, it is determined whether or not the sensor output large change flag is 1. If the sensor output large change flag is 1, the process proceeds to S613. On the other hand, if the sensor output large change flag is not 1, the process proceeds to S608.

In S613, it is determined whether or not the sensor direction is the same as the line-of-sight direction based on the flag information set in S505 of FIG. If the sensor direction is the same as or substantially the same as the line-of-sight direction, the process proceeds to S614. On the other hand, if the sensor direction is different from the line-of-sight direction, the process proceeds to S608. Here, the ranges in substantially the same direction are experimentally calculated by actual measurement values of the movements of the line of sight of many photographers.

In S614, the gain value used for the control duty detailed calculation is set to G as the pan gain value.
Store _small and proceed to S615. In S615,
The detailed calculation of the control duty supplied to the X motor driver 8 or the Y motor driver 12 which is the driver for driving the shake correction control motor is performed using the pan gain value G _small or the normal gain value G _normal obtained in S614.

As described above, in the image pickup apparatus having the shake correction mechanism of this embodiment, after the line-of-sight position of the photographer moves in the horizontal or vertical direction with respect to the optical axis of the lens device at a certain speed or more at a certain amount or more, When a predetermined amount of blurring occurs in the same direction or substantially the same direction as the moving direction of the line of sight after a predetermined time has elapsed from the time of this movement, it is determined that the pan operation is performed, and the normal gain value G _normal Instead of using the pan gain value G _small , the shake correction mechanism is driven in the suppressed state.

Therefore, when the observer decides to start pan photographing, moves the line-of-sight position in the pan direction, and after that, within a certain time, a blur detection output of a certain amount or more is generated by the movement of the photographing optical system in the pan direction. Is determined by intentionally performing the pan photographing operation, and by stopping the blur correction control in the same direction or substantially the same direction as the line-of-sight position moving direction, or by changing the control coefficient of the blur correction control, It is possible to stop the subject in pan shooting and perform panning shooting with the background shaken in the pan direction.

Further, the observer does not move the line-of-sight position in the horizontal direction or the vertical direction with respect to the photographing optical system, and the observer generates a blur detection output of a certain amount or more due to the movement of the line-of-sight position in the photographing optical system. In this case, the shake detection output is not intentionally panned, and it is determined that the detection output is due to camera shake, and the shake correction control is performed as it is, whereby shooting with a shake correction effect can be performed.

FIG. 7 shows a case where panning is performed in the horizontal direction with respect to the optical axis by using the conventional photographing apparatus in both the horizontal and vertical directions with respect to the optical axis of the photographing optical system. FIG. 5 is an explanatory diagram schematically showing a photographed image obtained when normal blur correction control is performed.

As shown in FIG. 7, even though the pan photographing is performed, the blur correction mechanism is activated, so that the panning photographing effect cannot be obtained and the photograph is contrary to the photographer's intention. You can see that it has ended.

On the other hand, FIG. 8 shows a case where when the pan photographing is performed in the horizontal direction with respect to the optical axis using the photographing apparatus of the present embodiment, the blur correction control is stopped only in the horizontal direction with respect to the optical axis. It is explanatory drawing which shows a photograph typically.

As shown in FIG. 8, when pan shooting is performed in the horizontal direction with respect to the optical axis, the follow shot shooting cannot be performed because the shake correction control in that direction is stopped.
I was able to take a picture that matched the photographer's intention.
