Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an independent finder type camera system in which the finder is independent of the camera and the camera does not have to be set up, and in particular, the field of view of the independent finder and the field of view of the camera are surely matched. Regarding the three-dimensional link mechanism.

[0002]

2. Description of the Related Art In a conventional camera, a camera body and a finder are integrally structured, and a photographer usually holds the camera and looks through the finder to take a picture.

From this form, as an improved type depending on the application,
As disclosed in JP-A-3-289893, the camera is supported by a camera rotation driving unit that rotates left and right so that the camera faces the headline of the photographer's head, and the camera is attached to a temple or hat of glasses and fixed. There is a system in which the camera rotation drive unit is driven by the output from the head angle detection switch mechanism so as to rotate the camera by a predetermined angle (angle difference between the headline and the line of sight).

Further, as disclosed in Japanese Patent Laid-Open No. 61-24386, there is a planar shape above the oscillator mounted on the helmet worn by the operator, in which the reception output of the radio wave changes according to the movement of the helmet. Provide an antenna. And
There is a system that detects the movement of the operator's head from the received output of this antenna and transmits a control command signal for controlling the orientation of the visual sensor.

Further, as in Japanese Patent Laid-Open No. 62-271691, a gyro on a helmet worn by an operator detects an angular velocity when the helmet is moving, and the attitude of the helmet is calculated using the angular velocity signal. . From these calculated attitude signals of the helmet, which change from moment to moment,
There is a system in which the TV camera control device controls the attitude of the TV camera to change the screen of the monitor TV according to the movement of the head of the operator.

As disclosed in Japanese Patent Laid-Open No. 4-86906, output signals of eye movements in the vertical and horizontal directions of the eye movement detector are introduced into the control device to calculate a control amount for the TV camera. There is a method in which a wireless signal is emitted from the calculation result, and is received by the unmanned vehicle side to control the direction of the equipped TV camera.

[0007]

However, in the conventional camera integrated with the finder, it takes time to hold the camera when the scene to be photographed is encountered, and misses the photo opportunity. A video camera or the like that takes a long time to take a picture gets tired because it is necessary to maintain a shooting posture held all the time. With a still camera, the subject becomes so nervous that I can't take a picture with a natural look. If both hands are blocked, such as when carrying sports or luggage, the camera cannot be held and shooting is impossible. Also, when fixing the camera to a helmet with sports etc., the optical axis of the shooting lens is aligned with the direction where the face is roughly facing, but since the finder cannot be seen, the accurate shooting range is not known and the target object is captured. There was a problem such as a high failure probability.

Further, in the case of the improved type, in the method of mounting the camera on the head, the camera must be mounted so as to face the head line of the photographer's head, and therefore the degree of freedom of the mounting position is small and a considerable part of the system is provided. Since it is attached to the head, it is not suitable for long-term shooting because it causes fatigue.

In a helmet equipped with an oscillator,
Since a planar antenna is installed overhead, the device becomes large and the portability is poor, and it is not suitable for outdoor shooting.

In the method of detecting the angular velocity of movement of the helmet worn by the operator, the helmet equipped with a gyro must be mounted, and it is necessary to confirm the photographing field of view of the camera on the monitor TV. It is not suitable for still cameras because it is large and complicated and consumes a lot of power.

The device using the eye movement detector also has a problem that the device is large and complicated and is not general.

The present invention has been made in view of the above-mentioned problems, and it is possible to free the photographer from the photographing operation of holding the camera near the face and looking into the finder provided integrally with the camera, and to simplify the construction. With the 3D link mechanism of the optical device, the influence of the high-brightness subject such as the sun is blocked and the field of view of the finder, which is independent of the camera, and the field of view of the camera are made to follow each other so that they can respond quickly and reliably. The purpose is to provide.

If it is ON, the camera 1 is facing upward, and the camera platform μ-COM 44 sends a signal from the Pk port to the vertical swing motor drive circuit 47 to drive the motor 48 by a predetermined unit amount in the downward swing direction. , The motor 48 drives a predetermined unit amount in the lower swing direction (S
119). If it is OFF, the camera 1 is not facing upward, and the camera platform μ-COM 44 moves from the Pk port to the vertical swing motor drive circuit 47 by a predetermined unit amount in the upper swing direction.
A signal is sent to drive 8 and the motor 48 drives a predetermined unit amount in the upper swing direction (S120). Then, again the platform μ-COM 44 inputs the signal of the encoder 50 through the Pm port, and the terminal 5 of the vertical swing encoder 50.
It is determined whether 0b is in the ON state with the movable terminal (S12).
1). If it is ON, the camera 1 is at the neutral position in the vertical swing direction, and the vertical swing motor 48 is stopped as it is (S122). On the other hand, if OFF, S again
Repeat steps 118 and thereafter.

After passing through S122, the camera platform μ-COM 44 transmits a signal indicating that the camera 1 is facing the front from the Pi port to the Ph port of the camera μ-COM 31 (S1).
23). The camera μ-COM 31 performs the determination of S3 again and confirms that the camera 1 faces the front.

The Pb port of the camera μ-COM 31 sends a visual field index illumination lighting signal to the visual field index illumination drive circuit 35, and the four camera visual field index illuminations 6 are turned on (S).
5).

At this time, the photographer faces a vertical white wall or the like at a predetermined distance (for example, about 2 m) and projects the camera visual field index illumination 6 on the white wall. Looking at the camera visual field index illumination image projected through the meniscus half mirror lens 10 of the independent finder 9, the super-imposed visual field frame 1
The four corners of the image of No. 1 are matched with the camera field index illumination image. If they do not match, the distance to the white wall is different from the predetermined distance (predetermined distance), so that the standing position is changed to match the four corners of the illumination image and the field frame image 11.

A timer (not shown) of the camera μ-COM 31 starts counting from the time when the visual field index illumination lighting signal is output, and the illumination image and the four corners of the visual field frame image 11 are counted by the time the timer is up. Match the remote control 18
When the field-of-view calibration SW19 is turned on, the remote control drive circuit 41 sends a pattern projection signal corresponding to the ON signal of SW19 from the signal transmission iRED 21 to the remote control receiver 5 of the camera 1 and the camera μ. -COM
It is transmitted to the Pc port of 31 (S6).

A distance measuring start signal is sent from the Pd port of the camera μ-COM 31 to the distance measuring means 36, and the distance measuring result by the distance measuring of the active auto focus is inputted from the Pd port. A distance D0 between the camera 1 and the white wall at the time of field-of-view calibration (hereinafter referred to as a reference distance) is calculated (S7).

At this point, the field indicator illumination 6 of the camera, which is no longer needed, is set to P of the camera μ-COM 31 in order to save power.
A turn-off signal is sent from the b port to the visual field index illumination drive circuit 35 to turn off the four camera visual field index illuminations 6 (S
8).

From the Pe port of the camera μ-COM 31, a camera top surface index illumination lighting signal is sent to the camera top surface index lighting drive circuit 37, and the camera top surface index lights 7 and 8 are turned on by the current supply from the drive circuit 37. (S9).

Then, the Pf port of the camera μ-COM31 is displayed.
The area sensor drive control signal is transmitted from the camera to the area sensor drive circuit 38, and the area sensor 15 receives an image of the upper surface index illuminations 7 and 8 of the camera as shown in FIG. First, an image output signal for capturing the image of the index illuminations 7 and 8 on the sensor light-receiving surface is created by capturing the light at the center of the light-receiving surface of the area sensor 15 (S10).

The index illumination 7 obtained by the area sensor 15,
The image output signal of No. 8 is transmitted to the Pg port of the camera μ-COM 31 (S11).

As information in a state where the field of view of the camera 1 and the field of view of the independent finder 9 are matched, the distance D0 between the camera 1 and the white wall obtained in S7 is stored in the camera μ-COM 31 and detected in S10. The image positions of the index illuminations 7 and 8 on the light receiving surface of the area sensor 15 are set to the camera μ-COM 31.
It is stored by the area sensor output storage means 32 (S1).

In order to notify the photographer that the field-of-view calibration has ended, the camera μ-COM 31
A signal for turning on the blinking finder illumination 40 is sent from the Pa port to the finder illumination drive circuit 39 of the independent finder 9 to turn on the finder illumination 40 (S13).

On the other hand, if the visual field calibration SW 19 of the remote controller 18 is not turned on from the start of counting the timer in S6 until the timer goes up, it is determined that the photographer has no intention of performing the visual field calibration. Proceed to S14. Here, in order to save the power consumption of the camera visual field indicator illumination 6 which is no longer needed, Pb of the camera μ-COM 31 is reduced.
A visual field index illumination turn-off signal is sent from the port to the visual field index illumination drive circuit 35 to turn off the light (S14). Then S again
Go to 2.

When the field-of-view calibration is completed, the power consumption is saved. Therefore, the index lights 7 and 8 on the camera upper surface are not always turned on, and the index lights 7 and 8 are synchronized with the sampling frequency of the area sensor 15 as needed. , 8 are blinked (S15).

The photographing operation is started, and the indicator illumination 7 in the current state,
The image position on the light receiving surface of the area sensor 15 of No. 8 is obtained (S15a). Whether the image positions of the index illuminations 7 and 8 currently being detected are changed with respect to the image positions of the index illuminations 7 and 8 on the light receiving surface of the area sensor 15 stored by the field-of-view calibration are determined by the area sensor. The output comparing means 33 makes a comparison, and if it changes within a predetermined time, it judges that there is a visual field movement, and proceeds to S17. If there is no field of view movement, S2
Go to 6. The area sensor outputs of the images of the index illuminations 7 and 8 currently detected are stored in the storage means 32 (S16).

As shown in FIG. 10, when the peak of the image signal output of Sn is sharper than that of Sm (contrast is large), the direction in which the motor 48 is moved in the upper swing direction by a small predetermined amount in S19. However, it is determined to be in the correct direction in which the contrast of the index image on the upper surface of the camera is increased (the photographer moved his / her head upward as shown in FIG. 9E), and the process proceeds to S21. On the other hand, if not, it is determined that the direction in which the motor 48 is moved is in the wrong direction in which the contrast of the index becomes small (the photographer moved the head downward or did not move the head vertically). Then, the process proceeds to S23 (S20).

Assuming that the direction in which the motor 48 is driven in S19 is the correct direction, the camera μ-COM 31 moves the camera μ-COM 31 to drive the motor 48 in the same direction.

Then, the process proceeds to S25.

On the other hand, if they are not equal, the process returns to S23 and the operation is repeated (S24).

If the contrasts of the indexes 7 and 8 are equal, a signal is transmitted from the Ph port of the camera μ-COM 31 to the Pi port of the camera platform μ-COM 44 so as to stop the motor 48 ( S25).

Regarding the processing of the camera platform μ-COM 44, referring to FIG. 7 (e) of the subroutine chart, the camera platform μ-COM 44 is operated by the camera μ-C from the Pi port.

The distance D obtained in S29 is compared with the reference distance D0 at the time of field calibration obtained in S7, and D
If it is equal to = D0, there is almost no parallax between the field of view of the camera 1 and the field of view of the independent finder 9, and it is determined that no correction is necessary, and the process proceeds to S32. On the other hand, if D ≠ D0, parallax has occurred, and it is determined that the field of view needs to be corrected, and the process proceeds to S31 (S30).

Reference distance D0 during field-of-view calibration
And the angle between the finder optical axis and the photographic lens optical axis of the camera obtained from the standard dimensions with the camera attached is β0, and the distance between the photographic lens optical axis at the camera and the finder position and the finder optical axis is Lc.

At the Pc port of the camera μ-COM31,
The input state of the SW2 signal from the remote controller 18 is detected for a predetermined time, during which the SW243 of the remote controller 18 is turned on.
By doing so, the remote control drive circuit 41 outputs a pattern projection signal corresponding to the ON signal of SW2 to the signal transmitting iRE.
It is sent from D21 to the remote control receiver 5 of the camera 1 and inputted to the Pc port of the camera μ-COM 31 to be detected, and S
Proceed to 33. When SW2 is OFF, the process proceeds to S34 (S32).

The process of S34 is the same as that of S15. S35 is S
Same as 10. Then, the process proceeds to S15a.

After the exposure in S33, it is determined whether the photographing is continued or the power is turned off and the photographing is finished.
When the power is not turned off and the photographing is continued, the process proceeds to S34. If the power is off, the process proceeds to S37 (S36).

If the signals 9 and 250 are input through the Pl and Pm ports (S263) and both terminals 249b and 250b are electrically connected to the movable terminals, the camera 201 is in the neutral position in both the left and right directions and the up and down directions (S264). It is determined that the camera faces the front and the camera μ-COM 231 is notified (S265).
If NO is determined in S264, the camera μ-COM23
A signal indicating that the camera 201 is not facing the front is transmitted to the camera 1 (S266).

Upon receiving these signals, the camera μ-COM
231 determines whether or not the camera 201 is facing the front, and if it is facing the front, the process proceeds to step S205. When not facing the front, the process proceeds to S204 (S20
3).

The camera μ-COM 231 sends a command signal for directing the camera 201 to the front from the Ph port, and then receives a signal from the camera platform μ-COM 244 (S2).
04).

Now, the processing by the camera platform μ-COM 244 will be described with reference to the program chart of FIG. 18, which is a subroutine of the program chart of FIG.

First, the command signal from the camera is received (S
271), and confirms the communication content, which is a command for the camera to face the front (S272). Pan head μ-COM which received order
244 inputs the signal of the encoder 249 through the Pl port, and determines whether the terminal 249a of the left / right swing encoder 249 is in the ON state with the movable terminal (S273). O
If it is N, the camera 201 is facing left and the camera platform μ-
The COM 244 sends a signal from the Pj port to the left / right swing motor drive circuit 245 to drive the motor 246 in the right swing direction by a predetermined unit amount, and the motor 246 drives in the right swing direction by a predetermined unit amount (S274). If it is OFF, the camera 201 is not facing left and the camera platform μ-COM
244 is a left / right swing motor drive circuit 245 from the Pj port
A signal is sent to drive the motor 246 by a predetermined unit amount in the left swing direction, and the motor 246 drives the left swing direction by a predetermined unit amount (S275). And again, the platform μ-
The COM 244 inputs the signal of the encoder 249 through the Pl port and outputs the signal to the terminal 249 of the left and right swing encoder 249.
It is determined whether or not b is in an ON state with the movable terminal (S27).
6). If it is ON, the camera 201 is in the neutral position with respect to the left and right swing direction, and the left and right swing motor 246 is stopped as it is (S277). On the other hand, if it is OFF, the steps after S273 are repeated again.

After passing through S277, the pan head μ-COM244
Inputs the signal of the encoder 250 through the Pm port and determines whether the terminal 250a of the vertical swing encoder 250 is in the ON state with the movable terminal (S278). If it is ON, the camera 201 faces upward, and the camera platform μ-CO
M244 is the vertical swing motor drive circuit 24 from the Pk port
A signal is sent to 7 to drive the motor 248 by a predetermined unit amount in the lower swing direction, and the motor 248 drives the predetermined unit amount in the lower swing direction (S279). If it is OFF, the camera 201 does not face upward, and the camera platform μ-COM244
Sends a signal from the Pk port to the vertical swing motor drive circuit 247 so as to drive the motor 248 in the upper swing direction by a predetermined unit amount, and the motor 248 drives in the upper swing direction by a predetermined unit amount (S280). And again, the platform μ-COM
244 inputs the signal of the encoder 250 through the Pm port, and determines whether the terminal 250b of the vertical swing encoder 250 is in the ON state with the movable terminal (S281). O
If the result is N, the camera 201 is at the neutral position in the vertical swing direction, and the vertical swing motor 248 remains in the stopped state (S282). On the other hand, if it is OFF, S2 again
The steps from 78 are repeated.

After passing through S282, the pan head μ-COM244
Transmits a signal indicating that the camera 201 is facing the front from the Pi port to the Ph port of the camera μ-COM 231 (S283). The camera μ-COM231 is S20.
By the processing of S3 and S204, it is confirmed that the camera 201 faces the front, and the process proceeds to S205 (S204).

The Pb port of the camera μ-COM 231 sends a visual field index illumination lighting signal to the visual field index illumination drive circuit 235 to turn on the four camera visual field index illuminations 206. At this time, an operation for matching the camera visual field index illumination image of the independent finder 209 with the four corners of the image of the visual field frame 211 is performed in the same procedure as in the first embodiment (S2).
05).

In S205, the timer is counted from the time when the camera visual field index 206 is turned on, the illumination image and the visual field frame are matched until the timer is up, and the visual field calibration SW 219 of the remote controller 218 is turned on. The light projection signal of SW219ON is sent from the signal transmission iRED 221 to the remote control reception unit 205 of the camera 201 by the 241, is transmitted to the camera μ-C0M 231, and proceeds to S207 (S206).

A distance measurement start signal is sent from the Pd port of the camera μ-COM 231 to the distance measuring means 236, and the distance measurement result is input from the Pd port to the camera μ-COM 231 and S
A distance D0 (reference distance) at the time of field-of-view calibration in 205 is calculated (S207).

At this point, the camera visual field index illumination 206 that is no longer needed is turned off to save power (S208).

A Pe port of the camera μ-COM 231 sends a light emitting element lighting signal to the camera upper surface light emitting element drive circuit 237 to turn on the camera upper surface light emitting element 207.
(209).

Subsequently, an area sensor drive control signal is sent from the Pf port of the camera μ-COM 231 to the area sensor drive circuit 238, and the area sensor 215 is turned on.
Two reflection images from the concavities 227 and 228 of the light projecting element 207 are captured at approximately the center of the light receiving surface of the sensor, and an image output signal for specifying the reflection image position is created (S21).
0).

Projecting element 2 obtained by area sensor 215
The image signals of the reflected images from the concavities 227 and 228 of No. 07 are transmitted to the Pg port of the camera μ-COM 231 (S211).

As information in a state where the field of view of the camera 201 and the field of view of the independent finder 209 are matched, S20
The reference distance D0 detected in 7 is set to the camera μ-COM231.
The position of the reflected image from the conic cubes 227 and 228 on the light receiving surface of the area sensor 215 in S210 is stored by the area sensor output storage means 232 of the camera μ-COM 231 (S212).

In order to notify the photographer that the field-of-view calibration has ended, the P of the camera μ-COM 231 is used.
A lighting signal is sent from the a port to the finder lighting drive circuit 239 of the independent finder 209 to turn on the blinking finder lighting 240 (S213).

On the other hand, if the SW 219 of the remote controller 218 is not turned on before the timer is up in S206,
Assuming that the photographer has no intention of calibrating the visual field, the process proceeds to S214. In S214, a turn-off signal is sent to the visual field index illumination drive circuit 235 to turn off the four camera visual field index illuminations 206, and then the process proceeds to S202.

To save power, the light projecting element 207 is switched to blinking in synchronization with the sampling frequency of the area sensor 215 as needed (S215).

In the photographing operation, the position of the reflected image from the corner cubes 227 and 228 on the light receiving surface of the area sensor 215 in the current state is obtained (S215a). The position of the reflection image of the concavities 227 and 228 which is being detected is changed with respect to the position of the reflection image of the concavities 227 and 228 of the area sensor 215 stored by the visual field calibration. Area sensor output comparing means 233
By comparing, if it changes within a predetermined time, it is determined that the visual field has moved, and the process proceeds to S217. Otherwise, proceed to S219. In addition, the area sensor output of the reflected image that is being detected is stored in the storage unit 232 (S21).
6).

After the field of view is moved with respect to the position of the reflected image of the area sensor 215 stored by the field calibration with respect to the reflected image from the corners 227 and 228, the corner 22 is moved.
The area sensor output comparison means 233 compares the positions of the reflected images from Nos. 7 and 228 to detect the amount of change in the left / right swing direction and the vertical swing direction, and then performs a predetermined calculation by the swing angle calculation means 234. The horizontal swing angle θ and the vertical swing angle ψ are obtained (S217).

The obtained values of θ and ψ are the camera μ-COM2.
It is sent from the 31 Ph port to the platform μ-COM 244. The platform μ-COM244 is a left and right swing motor drive circuit 2
The motors 246 and 248 are appropriately driven through the motor 45 and the vertical swing motor drive circuit 247 (S218).

Here, referring to the swinging subroutine in FIG. 19, the camera platform μ-COM 244 receives the signal from the camera μ-COM 231 from the Pi port (S25).
1). Check the received contents. Here, the drive direction and drive amount for driving the motor 246 up to the value of the angle θ and the motor 248 up to the value of the angle ψ are input (S252). The motor 246 is driven according to the received contents to match the field of view of the independent finder 209 in the left-right direction with the field of view of the camera 201 (S253). The motor 248 is driven according to the received contents to match the vertical field of view of the independent finder 209 and the field of view of the camera 201 (S256). A predetermined amount,
Completion of driving of the motors 246 and 248 is transmitted to the camera μ-COM 231 (S255).

When the motor drive end signal is received, the process proceeds to S215a again (S218a). In this way, the field of view of the camera 201 and the field of view of the independent finder 209 are always matched.

Next, SW1, S from the remote controller 218
The input state of the W2 signal is checked for a predetermined time, and S

Similarly, the light projecting element 207 is turned off via the camera upper surface projecting element drive circuit (S221).

A distance measuring start signal is sent to the distance measuring means 236, the distance measuring result is obtained from the distance measuring means 236, and the distance D between the camera and the subject is calculated (S222).

The obtained distance D is compared with the reference distance D0 at the time of field calibration, and if D = D0, it is determined that no correction is necessary and the process proceeds to S225. If D ≠ D0, parallax has occurred, so it is determined that the field of view needs to be corrected, and the process proceeds to S224 (S223).

As in the case of the first embodiment, the correction of the finder parallax is calculated based on D0 at the time of field calibration, the angle β0 between the photographic lens optical axis and the finder optical axis, and the distance Lc. , Calculation result μ-C0M2
A correction signal is sent to 44 to drive both motors 246 and 248 appropriately so that the fine parallax can be corrected. After that, the process proceeds to S225 (S224).

If the input state of the SW2 signal is detected for a predetermined period of time and the SW2 is turned on during that time, the light emitting signal of the iRED 221 is transmitted to the remote control receiver 205 and the camera μ-C is transmitted.

S227 is the same as S215. S228 is S
Same as 210. Then, the process proceeds to S215a.

After the exposure in S226, the photographing is continued or the power is turned on.
The FF determines whether or not the photographing is finished. If the photographing is continued, the process proceeds to S227, and if the power is off, the process proceeds to S230 (S229).
