DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera system having a function of notifying a subject of a photographing timing by using a remote control device of the camera.

[0002]

2. Description of the Related Art Conventionally, a self-timer function is often used when photographing a group photograph or the like, but a light-emitting device such as an LED provided at the front of a camera is used as a notification to a subject when the self-timer operates. There are many proposals by flashing or by sound (for example, JP-A-62-222228). In these inventions, the subject is notified by emitting light or sound from the camera body.

[0003]

However, considering the actual use situation, it is assumed that the distance between the camera and the subject is about several meters, and for example, the subject recognizes the sound emitted from the camera. This is very difficult, and it is considered impossible without using a loudspeaker instead of a mere speaker. Further, even if it has these functions, it is completely irrational as a camera that emphasizes portability.

[0004] The present invention is to solve such a problem.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a transmitter for transmitting a predetermined signal from a remote position of a camera body, and transmits a predetermined signal from the transmitter to the camera. A camera system for controlling the operation of the camera body in response to the received signal, comprising: a receiver for receiving the signal in the body, wherein the transmitter has a sound recording / reproducing function on the transmitter side. .

[0006] With this, the transmitter itself notifies by voice when shooting by remote control operation from the photographed person instead of notifying from the camera far away, so that the photographed person can easily recognize the photographing timing. Since the transmitter is equipped with an audio function, the portability of the camera is improved.

[0007] Further, a configuration may be adopted in which a predetermined signal is sent from the transmitter to the camera body after the notification sound is emitted from the reproduction function of the transmitter, and operation control of the camera body is started. Thereby, since the voice notification function and the camera operation function are linked, erroneous photographing can be easily prevented.

Further, a configuration may be provided which has a function of checking whether or not the signal from the transmitter is within a range in which the receiver of the camera body can receive the signal. In other words, even if a signal is transmitted from the transmitter to the camera body, it is difficult for the subject to understand whether or not the signal can be received by the camera body, which may cause erroneous photographing. Therefore, by providing a function that allows the user to easily check whether or not reception was possible on the transmitter side, if the result can be reported on the transmitter side, erroneous shooting can be prevented.

B is a camera body, 10 is a light receiving circuit for receiving a signal from a transmitter, 11 is a transmitting circuit for transmitting a signal to a signal transmitting / receiving circuit of the transmitter, 12 is a CPU, and 13 is an operation of the camera body. (For example, a release switch is turned ON).

As shown in FIGS. 1 and 2, by pressing a reproduction switch 7 for reproducing sound, the CPU 2 instructs to reproduce the sound previously recorded in the sound recording / reproducing apparatus 3 through the speaker 4, and starts reproduction. At the same time, a reproduction signal is transmitted to the camera body B. The signal received by the light receiving circuit 10 is identified by the CPU 12 and output to the sequence circuit 13 so as to blink or light an LED 14 which is a light emitting body disposed on the front of the camera until a release signal described later is received. Then, it has a function of notifying the subject both visually and visually by the user.

Next, after the reproduction is completed, a release signal is transmitted to the camera body B by the signal transmission / reception circuit 1. When the release signal enters the light receiving circuit 10 of the camera book B, it is input to the sequence circuit 13 via the CPU, performs a shooting operation in the same manner as normal remote control shooting, and switches such as a shutter are turned on. A function of interrupting photographing by turning on a reproduction switch 7 or a separately provided SW (not shown) during reproduction of audio may be provided.

After the photographing is completed, the CPU 12 of the camera body B outputs the signal to the transmitter A through the transmission circuit 11, and the CPU 2 of the transmitter A outputs the voice of “photographed” via the audio recording / reproducing device 3 to the subject. To notify the end of shooting. Further, in this case, the sequence circuit 13 on the camera B side may emit the strobe light (soft light emission may be used) even when the strobe is unnecessary, so as to notify the subject of the end photographing timing.

The transmitter A is provided with a recording switch 8 so that the photographer can freely record a unique voice such as "I will take a picture" or "High cheese" while the switch 8 is ON. it can. In addition, if the recording time is set to be the reproduction (timer) time, it is possible to reduce the time during which the subject is silent and still. Also, multiple voices can be recorded, and a function that can be selected at the time of shooting (playback) may be provided, and basic phrases such as countdown and “take a picture” “high, cheese” are set in advance by the manufacturer It may be recorded. Further, when the recording time is shorter than a certain time (for example, 10 seconds), it can be set so that the end of the certain time and the end of the reproduction are controlled so as to be synchronized with each other. good. A confirmation switch 6 is provided on the transmitter A side, and has a function of checking whether or not the reception range of the receiver of the camera body is within a range. Therefore, the confirmation signal is transmitted from the signal transmission / reception circuit 1 by turning on the confirmation switch 6 from the place where the transmitter A is arranged before photographing. When this confirmation signal is received by the light receiving circuit 10, the CP
U12 checks in a sequence circuit 13 whether the device is operable.
1 and transmits the signal to the transmitter as within the receivable range. The signal is received by the signal transmission / reception circuit 1, and the CPU 2 is configured to output the signal to the audio recording / reproducing device 3 and notify the user with a voice saying "It is in a photographable range".

In another embodiment for performing the confirmation signal, when the confirmation signal is received by the light receiving circuit 10, the CPU 12 causes the light emitting body of the LED 14 disposed on the front of the camera in the sequence circuit 13 of the camera to emit light or blink. The function may be such that whether or not the signal transmitted from the remote control device is in the receivable area can be confirmed by the camera. L
The light emitting body of the ED 14 may also serve as an LED (light emitting body) for notifying the subject of the photographing timing of the self-timer, an AF (ranging) auxiliary light, or the like.

The transmitter A is easy to hold and operate when used as a normal remote controller that does not emit sound.
Since it is conceivable that the camera is put on the ground when using it to emit sound, a mechanical mechanism (tilt mechanism) that can be installed stably and tilted to make it easier for the camera body to receive signals Etc.) may be provided.

On the other hand, the transmitter A has a plug 9 for connection to an external speaker (sound generating device), and by using the external speaker, it is possible to notify the subject with a clearer and louder sound. it can.

As another embodiment, as shown in FIG. 3, when a reproduction switch 7 is turned on, a time signal having time information of a reproduction signal and a sound reproduction time is transmitted to the signal transmitting device 1.
Send more. This signal is received by the light receiving circuit 10 and
It is output to the sequence circuit 13 via U12. At this time, the camera body B is configured to enter a shooting sequence after waiting for the time. Also, during this standby time, the CPU 2 of the transmitter A generates sound from the speaker 4 by the sound recording / reproducing device 3, and notifies the subject of the shooting timing.

According to this method, after the switch 7 is turned on, it is possible to prevent the transmitter from having to be turned to the camera side until the release signal is transmitted again. There is an advantage that it may be faced.

[0020]

According to the structure of the present invention, a transmitter such as a remote controller informs the photographing timing by voice.
It is easy for the user to understand the shooting timing. In addition, since the user can freely arrange the sound to be generated before shooting, and can clearly notify the subject of the sound, there is an effect that a more unique shooting can be performed.
