Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a still camera having video camera means for photographing a moving image and recording it on a first recording medium, and still camera means for photographing a still image and recording it on a second recording medium. It is related to the video camera with.

[0002]

2. Description of the Related Art Conventionally, at an event such as an athletic meet or an arts and crafts event, while a moving image is recorded on a recording medium such as a magnetic tape by using a video camera, a still image is recorded by using a silver salt film or the like. There are times when you want to shoot with a still camera that records.

There are some people who say that it is troublesome to carry both a video camera and a still camera separately when carrying them on a trip or the like. Therefore, a video camera with a still camera which responds to these is integrated with a still camera. Have been devised.

For example, in US Pat. No. 3,546,375, a movable mirror is arranged in the optical path of a photographing objective lens,
There is disclosed a compound camera capable of recording a still image and a moving image on different recording media by selectively switching the position of the movable mirror.

Alternatively, Japanese Utility Model Laid-Open No. 57-96444 discloses a video camera main body integrally provided with an optical photographing section for photographing on a silver salt film, or as a detachable body. Has been done.

Further, Japanese Patent Application Laid-Open No. 1-185533 discloses a camera with a confirmation function for displaying on a monitor an image signal from a photoelectric conversion image pickup device corresponding to an image formed on a silver salt film in a composite camera.

[0007]

However, in the above-described conventional example, the operability is prevented from becoming complicated by originally integrating the device for separately handling the moving image and the still image, and the photographing or reproducing intended by the user is prevented. It didn't have enough solutions to make it easy to do.

In the above-mentioned conventional apparatus, the first recording medium in which a moving image is photographed and the second recording medium in which a still image is photographed are
It is desirable that a one-to-one correspondence be made, that is, for example, when watching a video, you can immediately search for the corresponding still image, or when watching a still image, you can easily view the corresponding video at that time. It is desirable to be able to find it.

Further, at the time of photographing, the temporal relationship between the first recording medium for newly recording a moving image and the temporal relationship for the second recording medium for newly recording a still image is the same. The same is easier to understand. For example,
When recording a moving image on a videotape and a still image on a silver halide film at the same time, if the information just before recording is irrelevant temporally in each medium, it will be very troublesome to retrieve it later. It will take.

Here, in Japanese Patent Laid-Open No. 4-128730, in a camera using a film with a magnetic storage unit,
A configuration is disclosed in which a predetermined individual identification code is stored, the individual identification code written in the magnetic storage unit provided in the film is read, and it is determined whether or not they match. .

[0011] According to this, it is possible to manage the film personally, and it is possible to prevent photography except for the film of oneself. However, in this case, since two different recording media for moving images and still images are not handled at the same time, even if the film is identified by itself, it cannot be compatible with the recording medium on which the moving image is recorded.

The present invention has been made to solve the above problems, and when the first recording medium for recording a moving image or the second recording medium for recording a still image is taken out from the apparatus, It is an object of the present invention to provide a video camera with a still camera capable of keeping the same temporal connection of information recorded on both media.

[0013]

Therefore, in the video camera with a still camera according to the present invention, the video camera means for recording the moving image information in the first recording medium and the still image information in the second recording medium. A still camera-equipped video camera, comprising: a still camera unit for recording; and a control unit for controlling the video camera unit and the still camera unit in a main body of the apparatus, each of the first recording medium and the second recording medium. A first discharging means and a second discharging means for discharging the recording medium from the apparatus main body, a mode in which only one of the first recording medium and the second recording medium can be discharged, or both recording media can be discharged. And a mode selecting means for setting the mode, and when the mode capable of ejecting both recording media is set by the mode selecting means, the control means is the first recording medium or With the configuration and controls so as to discharge both the recording medium when performing any of the discharge operation of the second recording medium, it is intended to achieve the above object.

[0014]

With the above construction, when the mode in which both recording media can be ejected is set, the control means automatically makes an attempt to eject either the first recording medium or the second recording medium. Since both recording media are ejected to the first recording medium, the first recording medium in which the moving image information is recorded by the video camera means and the second recording medium in which the still image information is recorded by the still camera means at the same time are always paired. Can be handled as

An eject button 39 or the like for instructing is arranged.

FIG. 3 is a block diagram showing the configuration of the system control of this embodiment.

The structure is roughly classified into a camera microcomputer 40 that receives and controls operation inputs such as zoom, exposure, and AF, a mode microcomputer 41 that controls the release and mode setting of the camera body, and a mechanical microcomputer that drives and controls the tape recording / reproducing servomechanism. 42 and other video signal processing board 4
3, an audio signal processing board 44, a strobe board 45, a power supply board 46, etc. are connected to these.

FIG. 4 is a block diagram showing a portion necessary for explaining the present embodiment in the system control configuration.

When the film discharge switch 50 provided on the main body is pressed, the camera microcomputer 40 instructs the mode microcomputer 41, which controls the operation of the still camera, to discharge the film 5.

The mode microcomputer 41 energizes the motor (not shown) provided in the spool 29 in the rewinding direction, whereby the film 5 is stored in the cartridge 28. Here, the rewinding traveling state of the film 5 is monitored by a photo sensor 52 provided at a position facing the sprocket hole of the film 5.

If there is an unexposed frame on the film 5 when the film discharge switch 50 is input, the film 5 must be set again. Therefore, in this case, the mode microcomputer 41 controls so that the motor is stopped by the monitor of the photo sensor 52 before the leading end of the film 5 is stored in the cartridge 28.

After that, in order to inform that the rewinding of the film 5 is completed, the electronic viewfinder unit 1
Display on 8. At the same time, the mode microcomputer 41
Stores the number of shots of the ejected film 5 in the memory.

In this embodiment, since the number of shot images of a plurality of films can be stored in the memory, it is possible to combine with a plurality of video tapes by recording the corresponding numbers on the film. .

Simultaneously with the rewinding of the film 5, the camera microcomputer 40 instructs the mechanical microcomputer 42 to eject the video tape 47. Mechanical microcomputer 4
2 energizes a motor (not shown) in the video tape cassette storage unit 37 to store the tape wound around a drum (not shown) in the cassette and eject the video tape 47. Then, a display is displayed on the electronic viewfinder unit 18 to inform that the ejecting of the video tape 47 is completed.

The above series of operations have exactly the same effect as the above because the video tape 47 is discharged and the film 5 is discharged even when the user presses the eject button (tape discharge switch) 39.

On the other hand, the mode selection dial 36 is provided with a simultaneous discharge prohibition select switch 51. When the switch 51 is selectively operated, the camera microcomputer 40 controls so that only one of the instructed eject operations of the film or the video tape is ejected.

FIG. 5 is a flow chart of this embodiment.

[S103: Simultaneous discharge prohibition?] If the simultaneous discharge prohibition select switch 51 is turned on, the process proceeds to a sequence (S109) for independently discharging the film 5 or the video tape 47. If it is not ON, the process proceeds to S104.

[S104: Tape end or film end?] If the film discharge switch 50 or the tape discharge switch 39 is input and all the recording media on the input side have already been recorded, simultaneous discharge is not performed. Instead, the process proceeds to the sequence (S109) for ejecting only the recording medium on the side where the switch is input.

This is because when one recording medium is photographed to the end and the recording medium is replaced with a new recording medium, recording is performed on each recording medium without removing the other recording medium having an unrecorded portion. This is because there is no possibility that the time connection will be broken.

In the present embodiment, in the normal standard mode, when the recording of all the recording media ends, the rewinding sequence (S110) or the discharging sequence (S112) is automatically started. There is. However, it is possible to set the mode in which the automatic rewinding is not performed for the purpose of quickly changing the recording medium by saving the rewinding time. In this case, the recording medium is ejected by the film ejection switch. 50 or tape ejection switch 3
Therefore, the S104 sequence is required because the number becomes 9.

[S105: Film rewinding] When the process proceeds from S104 to S105, the mode microcomputer 41 energizes the film winding and rewinding motor (not shown) in the rewinding direction. A reduction gear head is connected to the motor, and the shaft of the film cartridge 29 is rotated to rewind the film 5.

"S106: Tape Eject" The mechanical microcomputer 42 energizes a motor (not shown) in the video tape cassette housing section 37 to house the video tape 47 in the cassette as described above and then eject it.
