Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera equipped with a line-of-sight detection device, and more particularly to a still camera and an electronic still camera capable of detecting camera shake by the line-of-sight detection device and reducing the influence of the camera shake. .

[0002]

2. Description of the Related Art As a conventional technique of a camera equipped with a visual axis detection device, for example, Japanese Patent Laid-Open Nos. 2-5 and 1-241 are known.
There is an example described in No. 511. The principle of line-of-sight detection in this conventional technique will be described with reference to FIGS.

Four bright spots are usually observed in the intraocular optical system. These bright spots are images of reflected light from the corneal surface to the back surface of the crystalline lens, which are called Purkinje images, and are called 1, 2, 3, and 4 images in order from the corneal surface.

The line-of-sight detection device detects the line-of-sight position using the Purkinje 1 image and the Purkinje 4 image among the Purkinje images. As shown in FIG. 4, the Purkinje 1 and 4 images are changed and observed by the rotation of the eyeball 41. For example, when looking at the center, as shown in FIG. 4A, the Purkinje 1 image and the Purkinje 2 image overlap. When viewing the right side and the left side, two images are separately observed as shown in FIGS. 4 (B) and 4 (C).

The movement amounts of the Purkinje 1 image and the Purkinje 4 image are as shown in FIG. 5 in the pupil center coordinates, and if the rotation angle of the eyeball is about ± 30 °, the movement amounts of both images are rotated. It is known that the angle changes almost linearly. Therefore, the rotation angle of the eyeball can be known by measuring these movement amounts.

The line-of-sight detection device is usually incorporated in the finder section of a camera, and these bright spots are detected by a light receiving element such as a two-dimensional CCD to obtain the barycentric position of each bright spot. Therefore, as shown in FIG. 5, the eyeball rotation angle at that time can be known from the relationship between the predetermined pupil center relative movement amount and the eyeball rotation angle, and the obtained positions of the respective bright spots. Therefore, it is possible to detect which position in the finder the photographer is looking at, that is, the line of sight of the photographer.

In the above-mentioned prior art, the Purkinje 1 and 4 images are used, but in addition to this, there is a case where the visual axis detection is performed by using a method using the Purkinje 1 image and the center of the pupil, a scleral reflection method, or the like. .

On the other hand, Japanese Patent Laid-Open No. 59-222823 discloses an example of a camera which detects a camera shake of a photographer and corrects the blur of a photographed image based on the detection result. In a camera shake correction method according to the related art, for example, a vibration detecting device such as an acceleration pickup using a piezoelectric element or a capacitance type displacement pickup detects a vibration amount of a camera caused by a shake, and based on the vibration amount. Then, the program line is shifted to the high speed side to reduce the influence of camera shake.

Further, by providing a camera shake correction lens movable in a direction orthogonal to the photographing optical axis of the camera, and moving the correction lens so as to cancel the vibration according to the detected vibration amount. , A method of performing camera shake correction is also performed.

[0010]

SUMMARY OF THE INVENTION In a camera equipped with a conventional line-of-sight detection device, in order to perform camera shake correction, a vibration detection device such as an acceleration pickup or a capacitance type displacement pickup using the piezoelectric element is used. As described above, it is necessary to provide a means for detecting the amount of vibration of the camera, which causes a problem that the number of parts and the manufacturing cost increase.

In the above conventional camera, the visual axis detection by the visual axis detection device is mainly used in the autofocus operation. For example, in the single mode autofocus used when the subject is a stationary object, an arbitrary focus position is selected by the photographer's line of sight until the focus is reached at the selected point.
In the continuous mode autofocus used when the subject is a moving object, the autofocus follows the line of sight of the photographer while the half-press SW is pressed, and the line-of-sight detection is performed until the full-press SW is pressed. The device is in use.

On the other hand, camera shake affects shooting.
Generally, it is a photographing operation period from the state of pressing the full-press SW to the opening / closing of the shutter.

The present invention has been made in view of the above points, and it is an object of the present invention to detect a camera shake that occurs when a photographing operation is performed by operating a shutter by using a line-of-sight detecting device. An object of the present invention is to provide a camera equipped with a line-of-sight detection device.

A further object of the present invention is to provide a camera capable of reducing the influence of camera shake by utilizing the detected camera shake amount.

[0015]

In order to achieve the above object, according to the present invention, in a camera provided with a line-of-sight detection device for detecting the line-of-sight of a photographer, the line-of-sight detection device is a light-receiving surface for detecting the line-of-sight. And a determination unit that determines a shift amount of the line of sight in the light receiving unit when performing a shooting operation by a shutter operation as a camera shake.

[0016]

In the present invention, it is assumed that the shift of the line of sight that occurs during the photographing operation is due to the camera shake, and the shift amount of the line of sight detected by the light receiving unit of the line of sight detection device at this time is determined as the camera shake amount.

For example, detected by the line-of-sight detection device,
The final focus position immediately before the release switch is pressed is the reference position, and the amount of displacement between the reference position and the subsequent line-of-sight position when the line-of-sight detection position deviates from the reference position due to camera shake during shooting ( The amount of deviation and the amount of camera shake are determined.

Further, by using the detected amount of camera shake, it is possible to perform control for reducing the influence of the camera shake and issue a warning indicating occurrence of camera shake.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a camera equipped with a line-of-sight detection device to which the present invention is applied will be described below with reference to FIGS. It should be noted that in the present embodiment, the description will be made assuming that the camera is capable of shooting with automatic exposure control (program mode).

The camera of the present embodiment, as shown in FIG.
CPU 1, aperture control circuit 2, shutter control circuit 3
, The line-of-sight detection device 4, the display unit 5, and the lens ROM 6
An exposure control circuit 7 and a release switch (SW) 8. In this embodiment, the camera body is provided with a lens ROM.
It is assumed that the replaceable lens barrel including 6 is connected.

Lens ROM 6 built in the lens barrel
Is information about the lens such as the focal length of the photographing lens provided in the lens barrel, and C
The information is output to the CPU 1 according to an instruction from the PU 1.

The exposure control circuit 7 executes automatic exposure control corresponding to a selected photographing mode, for example, a well-known program mode, and sets a shutter speed and an aperture value according to the photographing mode. , Shift the program diagram.

The CPU 1 detects the ON state of the release SW 8 and executes a series of controls relating to the photographing operation, as well as a control operation for detecting the hand shake and reducing the effect thereof which are the features of this embodiment.

As shown in FIG. 1, the CPU 1 includes a calculation unit 111 for calculating a permissible value for camera shake, a conversion unit 112 for converting the amount of shift of the line of sight detected by the line-of-sight detection device 4 into the amount of camera shake, and the camera shake. A shift control section 113 for controlling the shift operation of the program diagram performed by the exposure control circuit 7 in order to reduce the influence of the exposure control circuit 7; and a warning section 114 for displaying a warning on the display section 5 when camera shake is large. Have.

The calculation unit 111 calculates the permissible value of the blur amount from the shutter speed set by the exposure control circuit 7 and the focal length of the lens stored in the lens ROM 6. Generally, the shutter speed at which camera shake is likely to occur is determined by the focal length f of the lens, and 1 / f thereof is said to be a measure of the speed at which camera shake is less likely to occur.
That is, in the shooting in the program mode, the program line is changed so that the shutter speed becomes higher for a lens having a long focal length. Also, if the focal length is the same, camera shake is likely to occur when the shutter speed is low. Here, the permissible value of the blur amount is the limit of the amount of camera shake that does not affect shooting.

In this embodiment, the permissible blur value is determined based on the shutter speed and the focal length.
The method of setting the permissible value is not limited to this. For example, the shutter speed and the aperture value of the taking lens may be considered together, or, as in other embodiments described later, when a correction lens is provided, the correction capability of the correction lens It may be determined according to.

As shown in FIG. 6A, the line-of-sight detection device 4 is provided in the finder section 60 of the camera of this embodiment, and is provided between the optical paths of the eyepiece lens 64 and the pentaprism 66, for example. An optical path splitter 63, an area sensor 61 composed of an optical element having a two-dimensional light receiving surface, and an imaging lens 62 for forming an image of the light split by the optical path splitter 63 on the light receiving surface of the area sensor 61. Have. In this figure, 65 indicates the position of the eyeball of the photographer, and 100 indicates the optical path corresponding to the line of sight of the photographer.

In the following description, the case where the line-of-sight detection device 4 is provided with the area sensor 61 having a two-dimensional light receiving surface will be described, but the structure of the line-of-sight detection device that can be used in the present invention is not limited to this. For example, the configuration is not limited as long as the line of sight can be detected by the line-of-sight detection method described in the section of the above-mentioned related art.

However, the shape of the light receiving portion for detecting the line of sight in the area sensor 61 needs to detect a change in the position of detecting the line of sight which may occur due to camera shake during the photographing operation. For example, as shown in FIG. 6B, when the photographer pushes the release SW, a force is applied to the camera body in the direction of the arrow 600 to push the camera body downward or obliquely downward. It often happens because of it.

In such a case, the relative positional relationship between the eyeball 65 of the photographer and the viewfinder section 60 of the camera changes, and the new photographer's line-of-sight optical path 100 'is relative to the line-of-sight optical path 100 before the release. Will move upwards. Therefore, the area sensor 61 controls the change Δx in the line-of-sight optical path.
Is detected as the shift amount of the line of sight. The detected shift amount of the line of sight is output to the CPU 1 and converted into the amount of camera shake by the conversion unit of the CPU 1.

In the present embodiment, since the area sensor 61 is used, the shape of the light receiving portion of the line-of-sight detecting device 4 can be directly detected although the change Δx of the line-of-sight detecting position which occurs when the release SW 8 is pushed. May have other shapes. For example, a line sensor having a one-dimensional light receiving portion as a light receiving portion may be combined in a cross shape to detect changes in the line of sight in the vertical direction and in the horizontal direction.

The release SW 8 is usually provided at the right or left end of the upper part of the camera body. For this reason, most of the downward shifts that occur when the release SW is pushed in occur diagonally downward. Therefore, a configuration is provided in which only the line sensor extending in the lateral direction is provided as a light receiving unit, and only the lateral shift amount of the diagonally downward shift amount is detected to estimate the overall amount of camera shake. Also good.

The aperture control circuit 2 controls the aperture according to an instruction from the CPU 1. The shutter control circuit 3 is CP
The drive of the shutter is controlled according to an instruction from U1. The display unit 5 has a display screen 67 (see FIG. 6) provided in the finder unit 60, and under the control of the CPU 1, various displays such as a warning display indicating the occurrence of camera shake are displayed.

Next, the photographing operation including the camera shake correction control operation in this embodiment will be described with reference to the flow chart of FIG. The shooting operation of this embodiment is performed by the release SW8.
It is started by turning on. In the present embodiment, turning on both the half-press SW and the full-press SW is expressed as turning on the release SW8.

In step 201, the arithmetic unit 1 of the CPU 1
Reference numeral 11 sets a permissible value of the amount of camera shake (hereinafter referred to as a blur amount) based on the shutter speed set by the exposure control circuit 7 and the focal length of the photographing lens read from the lens ROM 6. In step 202, the shift amount of the visual line output from the visual line detection device 4 at this time is converted into a blur amount by the conversion unit 112. Here, the shift amount of the line of sight detected by the line-of-sight detection device 4 is, for example, the release SW.
It is calculated from the difference between the line-of-sight positions detected before and after 8 is turned on.

In step 203, it is determined whether the converted blur amount is less than or equal to the calculated allowable value. If it is less than the allowable value, the process proceeds to step 208, and if it is more than the allowable value, the process proceeds to step 204.

In step 204, the shift controller 113
Controls the exposure control circuit 7 to shift the program line set at that time to a higher speed side. Specifically, an allowable shutter speed that is larger than the allowable value calculated in step 201 and that can be ignored for the blur amount calculated in step 202 is calculated, and the calculated shutter speed is calculated. The program line corresponding to the shutter speed is set.

Considering, for example, EV12, the aperture is F5.6 and the shutter speed is 1/125 in FIG. 3A, and the aperture is F4 and the shutter speed is in FIG. 3B. It is 1/250. Before the release SW8 is turned on, the program line of FIG. 3A is set, and the shutter speed of the allowable limit according to the camera shake amount detected by the line-of-sight detection device 4 is 1/250. If calculated, then FIG.
The program line in (a) is shifted to the program line in FIG. 3 (b).

In step 205, the arithmetic unit 111 sets the shutter speed reset in step 204,
The allowable value of the blur amount is reset based on the focal length of the lens. In step 206, the line-of-sight detection device 4
The conversion unit 112 obtains the blur amount from the shift amount of the line of sight output from the.

In step 207, it is judged whether or not the obtained blurring amount is less than or equal to the allowable value set in step 205, and if it is less than or equal to the allowable value, the process proceeds to step 208, and if it is more than the allowable value, the process proceeds to step 209. .

In step 208, the aperture control circuit 2 and the shutter control circuit 3 drive the aperture and shutter of the camera to execute the exposure operation, and after the exposure is completed, the flow is ended.

In step 209, the warning unit 114 controls the display unit 5 to display a display warning the photographer of the occurrence of camera shake, and the CPU 1 stops the exposure operation and ends the flow.

According to the present embodiment, the camera shake amount is detected by the line-of-sight detection device 4, and if the detected shake amount is larger than the allowable value, a camera shake warning is issued to warn the photographer. It can be emitted, and the effect of blurring can be reduced by increasing the shutter speed.

Furthermore, according to the present embodiment, the visual axis detecting device can be effectively utilized and the camera shake can be detected in the photographing operation after the release SW is turned on, which has not conventionally been used. It is possible to omit a sensor that detects vibration such as an acceleration sensor that has been conventionally used, and thus, it is possible to reduce the number of camera parts and the manufacturing cost.

In the present embodiment, the exposure operation is not performed when the blurring amount corresponding to the shift amount of the visual line detected by the visual line detecting device 4 does not fall below the set allowable value of the blurring amount. However, if the photographer continues to press the release switch after ignoring the effect of blurring to some extent because the program line has shifted to the high speed side and displaying the camera shake warning, However, regardless of the photographer's intention to shoot, the exposure operation may be started.

Further, in the present embodiment, the warning of the occurrence of camera shake is displayed in the finder section 60. However, instead of displaying the warning, the warning may be generated by voice or the like. Alternatively, both of these warning means may be combined.

Further, although the present embodiment has been described by taking as an example a camera that performs automatic exposure control, the camera to which the present invention is applied is not limited to this. For example, the configuration may be such that only a warning is given without reducing or correcting the influence of camera shake. That is, the blur amount obtained by converting the shift amount of the line of sight detected by the line-of-sight detection device 4 and the permissible value of the blur amount set at that time are compared, and a blur amount larger than the permissible value is detected. Alerts you when
It may be configured to call the photographer's attention.

Further, in the present embodiment, the camera in which the lens can be exchanged has been described, but the present invention can be applied to a camera equipped with a lens-integrated visual axis detection device as in the case of the present embodiment. It is possible to provide a camera capable of detecting the amount of blur and reducing the influence of the blur and issuing a warning according to the magnitude.

Next, another embodiment equipped with the visual axis detection device to which the present invention is applied will be described with reference to FIGS.

In the above embodiment, when the detected blur amount is equal to or more than the allowable value, the program line is shifted to reduce the influence of camera shake, but in the present embodiment, the lens barrel together with the photographing lens is aimed.

Further, the correction lens drive mechanism control circuit 702 is obtained by the CPU 1.
The driving direction and the driving amount of the correction lens are controlled according to the blur amount and the direction in which the blur occurs. Next, the photographing operation including the camera shake correction control operation in the present embodiment will be described with reference to the flowchart of FIG. explain. The photographing operation of this embodiment is started by turning on the release SW8. In this flowchart, steps 801 to 803 are steps 201 to 201 in FIG.
Step 203 and steps 806 and 807 are the same as steps 208 and 209, respectively, and detailed description thereof will be omitted.

In step 801, the arithmetic unit 111 determines the shutter speed set in the exposure control circuit 7 and
The allowable value of the blur amount is set based on the focal length stored in the lens ROM 6. In step 802, the shift amount of the visual line output from the visual line detection device 4 at this time is converted into a blur amount by the conversion unit 112.

In step 803, the CPU 1 determines whether or not the converted blurring amount is less than or equal to the calculated allowable value. If it is less than or equal to the allowable value, the process proceeds to step step 806, and if not, the process proceeds to step 804. move on.

In step 804, the presence / absence of a correction lens is determined by the determination unit 701 of whether or not a correction lens capable of reducing the influence of camera shake is attached to the lens barrel attached to the camera body at this time. judge.
If it is determined that there is no correction lens, step 80
8, the camera shake warning is displayed as in the above embodiment, the exposure operation is stopped, and the flow is ended.
