Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remotely controllable image capturing apparatus which operates a camera from a remote position to capture an image.

[0002]

2. Description of the Related Art As a photographing device which enables a photographer to change the framing and determine the framing while the photographer is away from the camera, the signal light from the transmitter of the optical remote controller is detected,
An imaging device has been proposed that estimates the position of the transmission device based on this and follows the direction of the camera accordingly (for example, Japanese Patent Laid-Open No. 2-280129).

[0003]

However, shooting is performed by detecting the signal light from the transmitter of the optical remote controller, estimating the position of the transmitter of the optical remote controller, which is the light source, and controlling the orientation of the camera accordingly. As a matter of course, the apparatus does not perform framing as the photographer intends until the signal from the transmitter of the optical remote controller is detected, the signal is driven to change the direction according to the signal, and the signal is stopped. If shooting is performed before that, the framing will not be as intended, and it may be an image flowing in the driving direction.

An object of the present invention is to provide an improved photographing apparatus which solves the above-mentioned problems in the prior art.

[0005]

The photographing device of the present invention has a "following" function of detecting the signal light from the transmitter of the optical remote controller, estimating the position of the transmitter, and pointing the camera in that direction. The apparatus is provided with means for detecting the end of the "follow-up" operation and starting photographing, and automatically taking the picture in conjunction with the end of the "follow-up" operation.

When the switch 50, which is the shutter release switch of the remote controller, is turned on, the command encoder 55, which has received the signal, generates a signal pulse train ((b) in FIG. 3) instructing shutter release and applies it to the modulator 54.

As shown in (e), the modulated signal is input to the buffer amplifier 56.

The switching means 57 is turned on / off based on the modulation signal given through the buffer amplifier 56 to make the light emitting element 58 blink according to the modulation signal, and the modulation signal is output from the transmitting device 11 as signal light. It

At 6, 17, 18, and 19, frequency components other than the direct current component and the carrier signal due to external light are deleted, and only the signal component is output. Next, the demodulator 20 demodulates the sum of the signal components of the optical sensor 4 as a modulation signal to obtain the original signal pulse train. This demodulated signal pulse train is decoded by the instruction decoder 21, and when the switch 50 is on, the shutter release operation signal is given to the camera body 22 via the OR gate 61.

When turned on, the command encoder 55 provides the modulator 54 with the signal of (f) of FIG. 3 as a command signal. The modulator 54 receives the command signal from the command encoder 55 (FIG. 3 (f)),

This output is given to the switching means 57 via the buffer amplifier 56, the light emitting element 58 blinks according to the modulation signal by the switching means 57, and the modulation signal is output as signal light. By the way, switch 5
When all of 0, 51 and 52 are in the off state, the output of the command encoder 55 is as shown in FIG. 3 (h), and accordingly, the output of the modulator 54 is in the off state as shown in FIG. 3 (i). Will remain. Therefore, the light emitting element 58 also remains off, and no signal light is output.

The signal light emitted from the remote control transmitter 11 is imaged on the optical sensor 4 via the optical lens 3 in the remote control receiver 2.

Since the optical axes are approximately coincident with each other, they are located in the center of the optical sensor 4, and the respective outputs S _RUP , S _LUP , S _LIO , and S of the sensor divided into upper, lower, left, and right
_RIO is equal. When the image of the signal light is formed on the left side of the optical sensor, that is, when the remote control transmission device 11 is on the right side of the optical axis when viewed from the camera, each output of the divided sensors is (S _RUP + S _RIO ) <(S _LUP + S _LIO ), the direction in which the remote control transmitter 11 is present can be detected based on the magnitude relation between the outputs of the divided sensors. Next, after the outputs S _RUP , S _LUP , S _LIO , and S _{RIO of} the sensor 4 are amplified by the amplifiers 12, 13, 14, and 15, respectively,
The bandpass filters 16, 17, 18 and 19 remove noises other than the direct current component and the carrier signal frequency due to external light, respectively, and further, the integrators 23, 24, 25 and 26 integrate the respective signals, respectively. It is given to the position determination means 27. On the other hand, the bandpass filters 16, 17, 18, 19

If it is, the output of the upper sensor is compared with the output of the lower sensor, and if the output of the upper sensor is large, the camera body is driven upward, and if the output of the lower sensor is large, the camera body is driven downward. Generate a drive signal to cause the left sensor output to compare with the right sensor output,
If the sensor output on the left side is large, to the left side, if the output from the right side sensor is large, to the right side, a drive signal is generated to drive the camera body 22, respectively, and drive circuits 28 and 2 are generated.
Give to 9. The drive circuits 28 and 29 are position determining means 27.
The actuators 8 and 5 are respectively driven according to the output control signal of FIG.

The output of 5 controls ON / OFF of the light emitting element 67.
Reference numeral 67 is a light emitting element that displays from the completion of "following" to the execution of photographing.

The operation of the above configuration will be described below.
Remote control release switch 50 of remote control transmitter 11
When is operated, the command encoder 70 outputs the signal shown in FIG. 9B as a signal pulse train. Modulator 54
Generates a carrier signal (Fig. 9 (a)) output from the timing generator 53 and a signal pulse train (Fig. 9 (b)) from the command encoder 70 as a modulation signal, and creates a buffer 56, This modulated signal is output as an optical signal from the light emitting element 58 via the switching means 57.

This signal light is imaged on the sensor 4 by the optical lens 3 and converted into an electric signal, and the amplifiers 12, 13,
Bandpass filters 16 and 1 amplified by 14 and 15
Frequency signals (ie, noise) other than the signals are removed at 7, 18, and 19 and are given to the demodulator 20.
Are demodulated by and input to the instruction decoder 68. Since the signal at this time is the signal when the switch 50 is operated ((b) in FIG. 9), the instruction decoder 68 generates a remote control release signal, which is given to the camera body 22 via the OR gate 61. The camera body 22 executes shooting. At this time, neither the "follow-up" release mode signal of the instruction decoder 68 nor the "follow-up" release time signal after a predetermined time has been generated. Therefore, the enable signal is given to the position determination circuit 27 via the OR gate 71. No
The actuators 5 and 8 for "following" are not driven at all.

When the release switch 52 is operated after "following" in the remote control transmitter, the command encoder 7 is operated.
0 outputs the signal of FIG. 9 (f) as a signal pulse train.
The modulator 54 uses the carrier signal output from the timing generator 53 ((a) in FIG. 9) and the signal pulse train from the command encoder 70 ((f) in FIG. 9) as the modulation signal based on the output in FIG. 9 (g). That is, the modulated signal is output as an optical signal from the light emitting element 58 via the buffer 56 and the switching means 57.

The signal light emitted from the remote control transmitter 11 is imaged on the optical sensor 4 via the optical lens 3 in the remote control receiver 2. In this case, for example, if the remote control 11 is located at the center of the shooting screen, the image of the signal light (the image of the light source of the remote control transmitter) will be the optical axis of the shooting optical system of the camera body and the lens 3.
Since the optical axes of the unit including the optical sensor 4 and the optical sensor 4 are approximately coincident with each other, the outputs S _RUP , S _LUP , S _LIO , and S of the sensor located at the center of the optical sensor 4 and divided vertically and horizontally.
_RIO is equal. If the image of the signal light is formed on the left side of the optical sensor (that is, if the remote control transmitter 11 is on the right side of the optical axis when viewed from the camera), each output of the divided sensors is (S _RUP + S _RIO ) <(S
_The direction in which the remote control transmitter 11 is present can be detected based on the magnitude relation between the outputs of the divided sensors, such as _LUP + _SLIO ).

Next, the amplifiers 12, 13, 14, and 15 amplify the respective outputs S _RUP , S _LUP , S _LIO , and S _RIO of the divided sensors, and then the band pass filters 16, 17, 1 are amplified.
At 8 and 19, noises other than the direct current component and carrier signal frequency due to external light are removed, and integrators 23, 24 and 2 are provided.
The signals are integrated at 5 and 26, and the position determination circuit 27
Given to. On the other hand, a signal is also applied to the demodulator 20 from the bandpass filters 16, 17, 18, and 19, and after being demodulated by the demodulator and applied to the instruction decoder 68, a "following" post-release mode signal is output.

As a result, the enable signal is given to the position judging circuit 27 via the OR gate 71, and the position judging circuit 27 generates outputs corresponding to the inputs S _RUP , S _LUP , S _RIO and S _LIO . That is, when the sum of the integrated signals reaches a predetermined value, the position determination circuit 27 compares the output of the upper sensor with the output of the lower sensor as shown in FIG. Is generated in the upward direction, and if the output of the lower sensor is large, a drive signal for driving the camera body in the downward direction is generated. If the outputs of the upper and lower sensors are substantially equal, a vertical drive stop signal is generated and the left sensor output is compared with the right sensor output. If the output of is large, a drive signal for driving each is generated to the right. If the outputs of the left and right sensors are substantially equal, a drive stop signal in the left and right direction is generated and given to the drive circuits 28 and 29. The drive circuits 28 and 29 drive the actuators 8 and 5, respectively, as shown in FIG. 6, according to the output control signal of the position determination circuit 27.

By repeating the integration of the signals and the position determination as described above, the photographing optical axis of the camera is directed to a certain direction of the remote control transmission device and stopped.

When all the outputs of the position judgment circuit 27 become "0" and the camera body stops, the output of the NOR gate 40 becomes "1" and the state of the switch 38 is input AN.
The output of the D gate 62 becomes "1" accordingly, and A
The ND gate 63 outputs "1" by this output and the release mode signal after "following" of the instruction decoder 68, and the output becomes "1".
Give to 2. As a result, when the switch 52 is operated, photographing is performed immediately after the completion of the "follow-up" operation.

Next, the operation of the remote control transmission device 11 when the release switch 69 is operated after a predetermined time has passed after "following" will be described. When the switch 69 is turned on, the command encoder 70 outputs the signal shown in FIG. 9D as a signal pulse train. The modulator 54 creates the signal of FIG. 9E as a modulation signal from the carrier signal (FIG. 9A) output from the timing generator 53 and the signal pulse train (FIG. 9D) from the command encoder 70, and buffers it. 5
6. The modulation signal is output as an optical signal from the light emitting element 58 via the switching means 57.

In the remote control receiver 2, the signal light emitted from the remote control transmitter 11 is imaged on the optical sensor 4 via the optical lens 3. In this case, for example, if the remote control 11 is located at the center of the shooting screen, the image of the signal light (the image of the light source of the remote control transmission device) will have the optical axis of the shooting optical system of the camera main body and the optical axis of the unit including the lens 3 and the optical sensor 4 Since they approximately match, each output S _RUP , S _LUP , S _LIO , S of the sensor located at the center of the optical sensor 4 and divided vertically and horizontally
_RIO is equal. Further, if the image of the signal light is formed on the left side of the optical sensor (that is, if the remote control transmitter 11 is on the right side of the optical axis when viewed from the camera), each output of the divided sensors is ( S _RUP + S _RIO ) <(S _LUP
+ S _LIO ), the direction in which the remote control transmitter 11 is present can be detected based on the magnitude relationship between the outputs of the divided sensors.

The outputs S _RUP , S _LUP , S _LIO , and S _RIO of the divided sensors are amplified by amplifiers 12, 13, 14, and 15, respectively, and then band-pass filters 16, 17, 18, and 1.
9 removes DC components due to outside light and noise other than the carrier signal frequency, and integrators 23, 24, 25,
At 26, the signals are respectively integrated and given to the position determination circuit 27. On the other hand, the bandpass filter 1 is also included in the demodulator 20.
Signals from 6, 17, 18 and 19 are demodulated by the demodulator, and when given to the command decoder 68, a release mode signal is output after a predetermined time after "following".

As a result, the enable signal is applied to the position determining circuit 27 via the OR gate 71, and the position determining circuit 27 outputs the signals in accordance with the inputs S _RUP , S _LUP , S _RIO and S _LIO . That is, when the total sum of the integrated signals reaches a predetermined value, the position determination circuit 27 compares the output of the upper sensor with the output of the lower sensor as shown in FIG. If the output of the lower sensor is large, the drive signals for driving the camera body are generated downward. Also, if the outputs of the upper and lower sensors are substantially equal, a vertical drive stop signal is generated. Further, the left sensor output is compared with the right sensor output, and a drive signal for driving the camera body is generated to the left if the left sensor output is large, and to the right if the right sensor output is large. If the outputs of the left and right sensors are substantially equal to each other, a drive stop signal for the left and right directions is generated to drive the drive circuits 28 and 29.
The horizontal movement of the camera body is prohibited via.

The drive circuits 28 and 29 drive the actuators 8 and 5, respectively, as shown in FIG. 6, in response to the output control signal of the position determination circuit 27.

By repeating the integration of the signals and the position judgment as described above, the photographing optical axis of the camera is directed to a certain direction of the remote control transmission device and stopped.

When all of the outputs of the position judgment circuit 27 become "0" and stop, the output of the NOR gate 40 becomes "1", and when the state of this and the switch 38 is input, the output of the AND gate 62 follows it. The output of the AND gate 64 becomes "1" according to this signal and the release mode signal of the instruction decoder 68 after a predetermined time after "follow up" (release start signal after a predetermined time after "follow up"). The timer 60 operates. While the timer 60 is operating,
After the start signal is generated, the timer 6 sends a "predetermined time" clock complete signal.
Until generated from 0, the exclusive OR gate 65 sets the output to "1" and causes the switching means 66 to turn on the light emitting element 67. Timer 60 is "predetermined time"
When the clock is finished, the output of the gate 65 becomes "0" by the completion signal and the light emitting element 67 is turned off. Also, this completion signal is ORed as a release signal after a predetermined time after "following"
It is given to the camera body 22 via the gate 61.

As a result, when the switch 69 is operated, "follow-up" is performed, and after the "follow-up" operation is completed, display is performed by the light emitting element for a predetermined time, and then photographing is performed.

[Embodiment] As described above, in the present invention, the photographing is automatically executed after the "follow-up" operation, so that the photographer can easily perform the photographing without confirming the state of the "follow-up" operation. In addition, I was able to do so that I did not need any new act of release for release.

Further, by displaying the image before photographing, the photographer can use it with more peace of mind.
