Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a film image recording system for photographing images of silver salt negative or positive films.

[Prior art]

Conventionally, a system is known in which a camera body is attached to a film adapter and film photography is performed.

[Problem that the invention is trying to solve]

However, this type of camera had the disadvantage that the camera body was oriented downward, making it difficult to operate the buttons for recording. Another disadvantage is that if the camera is not attached to a film adapter, the camera may accidentally take a picture while in film shooting mode (negative/positive reversal mode).

[Means to solve the problem]

According to the present invention, a switch for film photography is provided on the film adapter side, so that photography can be easily performed. Additionally, in film shooting mode, the recording trigger switch on the camera body is disabled to prevent erroneous shooting.

A light receiving window provided in the receiver receives an infrared light signal from a wireless remote controller (not shown).

When photographing with film, first connect the camera body 1 to the film adapter 3 as shown in FIG. Then, the film 4 is set and the illumination light source 5 is turned on. As a result, the image on the film 4 passes through a normal photographic lens optical system (not shown) of the camera body, and is converted into an image signal by an image sensor (not shown). Here, lighting is turned on by turning on the switch 6 provided on the film adapter 3, and recording is performed by turning on the recording switch 14.

Next, an example of the circuit configuration of the camera body 1, interface adapter 7, film adapter 3, and power coupler 2 will be described in detail with reference to FIG.

In Figure 2, the block L surrounded by a dotted line is the camera body, the block 2 also surrounded by a dotted line is the gage source coupler, the block 3 also surrounded by a dotted line is the film adapter, and the block 7 also surrounded by a dotted line is the interface adapter. , is.

A signal line cable 8 from the film adapter 3 is connected to the interface adapter 7 via a connector 11.
It is directly connected to the cable 9 to the L side of the camera body. Further, from the video output terminal, the Y/S signal and chroma signal from the cable 9 to the camera body 1 are sent to a mixing circuit 701.
The signals are added together and output as a video signal.

In the power supply converter 2, 21 is a sensor that receives infrared light from an infrared wireless remote control, and 22 is a one-chip microcomputer that has a serial data communication boat, and this boat can be switched between functions as a communication boat and a normal output port. Selectable (for example, NECμPD7
564 etc.). 23 is a regulator that supplies power for the microcomputer. This regulator is controlled by a control signal/CPU0N28 from the camera body. When CPU0N becomes Low, the regulator becomes ENABLE and the microcomputer 22 operates. The microcomputer 22 has switches 14.15.1 for the film adapter 3.
6.36 signals are connected, and the microcomputer 22 can detect the states of these switches. 24 is a light receiving sensor output, which is detected by the microcomputer 22 and identifies the code of the remote control. 25 to 27 are serial communication lines between the camera body I and the microcomputer 22 in the power coupler 2, 25 is a data line for serial communication, 26 is a clock line for serial communication, and 27 is a BUSY line for serial communication.

Next, in the camera body 1, 101 is a microcomputer that controls the camera body, and is a microcomputer (for example, Mitsubishi: M37410) that has a standby mode that operates with low power consumption and an operation mode that consumes more power but operates at high speed. 102 is a serial-parallel converter for converting serial communication data from the microcomputer 22 in the power supply coupler into parallel data and communicating data with the microcomputer 101 in the camera body l. Here, the data line 25 is connected to the microcomputer 10.

103 and 104 are regulators for stably supplying voltage to the microcomputer 101, 103 is for high-speed operation of the microcomputer, 104 is for low consumption mode of the microcomputer, and 10
The regulator voltage output of No. 3 is higher than that of No. 104. A voltage changeover switch 105 changes over the power supply voltage of the microcomputer 101 as necessary. 106 is an Sv left camera imaging recording/reproducing processing system block. A video signal reproduced from a video floppy (not shown) or a video signal from an image sensor film is output as a Y+S signal and a C (chroma) signal. A character generator 107 is an IC for displaying characters, etc. on a television monitor (not shown).

The microcomputer 101 of the camera body 1 receives the control signal 28
/CPU0N is set to Low (by this, the regulator 23 in the power coupler 2 becomes ENABLE and the microcomputer 22 operates. In this state, the microcomputer 2 in the power coupler
2 detects the state of the film adapter switch and serially transfers code data based on this to the serial/parallel converter 102 in the camera body.

A microcomputer 101 in the camera body takes in data in a serial-parallel converter 102 and controls the camera body based on this data.

These steps are shown in a flowchart as shown in FIG.

The operation will be explained below.

First, it is checked by Sl whether new data is prepared in the serial/parallel converter 102 (Ready?).

If it is Ready, data is fetched in S2.

In S3, check the data obtained in S2 and switch BLON3.
Check if 6 is on. If it is ON, check whether switch N/P16 is negative or positive in S4. S for NEGA
Step 5 sets the camera's recording mode to NEGA/POS1 inversion mode (NEGA mode). If it is POSI, the recording mode of the camera is set to NEGA/Po5t non-inversion mode (PO3I mode) in S6.

Next, if the recording trigger switch 14 is ON in S7, a film is photographed in S8 and the process ends. switch 14
If it is OFF, it returns to Sl again. If SL is not Ready or switch BLON36 is OFF in S3, the recording trigger switch 108 on the camera body side is set in S9.
If is ON, a normal photographing sequence is performed in SIO. This is a sequence for recording general subjects, not film, so a detailed explanation will be omitted here. If the switch 108 is OFF in S9, the process returns to Sl.

As described above, when the BLON switch 36 is ON, that is, in film mode, the recording trigger switch on the camera body side is ignored, and only the recording trigger by the switch 14 on the film adapter side is valid.

Furthermore, when the BLON switch 36 is OFF, that is, when not in film mode, the recording trigger switch on the film adapter side is ignored, and the switch 10 on the camera body side is ignored.
Only the recording trie by 8 is valid.

[Other Examples]

In the embodiment described above, the illumination switch of the film adapter and the film photographing mode switch are linked together, but they may be linked by a relay or the like.

For example, the 0N10FF of the film photography mode switch may be connected so that it can be detected by a microcomputer as in FIG. 2, and the output of this film photography mode switch may be connected to a relay, which then turns the illumination to 0N10FF.

Further, in the embodiment described above, the illumination of the film adapter is turned on by a switch, but the present invention is also effective even if the illumination is turned on by connecting the cable 8 to the interface adapter 7. That is,
In Fig. 2, the switches 6 and 36 are always ON, that is, normally, (this is the same as the switch part 6 and 36, so you can omit the switch part 6 and 36 and short-circuit that part. By doing this, the microcomputer 22 Connection of the cable 8 and lighting of the lighting can be detected.

In this embodiment, the DATA line is used as a signal for changing the microcomputer of the camera body from standby to operating mode, but this may also be a CLK line necessary for communication.

Alternatively, communication may be made not only in one direction but also in both directions from the microcomputer on the power coupler side to the main body side.

Alternatively, although the communication method is clock synchronous in this embodiment, it may be asynchronous.

In this embodiment, a serial-to-parallel converter is installed in the camera body, but the microcomputer in the camera body and the microcomputer in the power coupler communicate directly in serial, and in the above embodiment, the film mode is set using the switch on the film adapter. The switch for recording was selected accordingly. In the present invention, the recording trigger switch is selected depending on whether the film mode is set or not. Therefore,
The film mode can be set not only in this embodiment, but also by providing a switch on the camera body side, or by using a remote control, etc. The present invention is effective regardless of the setting method.

Further, in this embodiment, it is called a recording trigger switch, but if this switch is used for other functions, the other functions may or may not be restricted depending on the film mode.

[Effects of the Invention] As explained above, by providing the recording trigger switch for film mode on the film adapter side, it is possible to improve the operability for recording when the camera body is attached to the film adapter. It's now possible.

It is also now possible to prevent the mistake of pressing the record button on the camera body while in film mode, resulting in an inverted negative/positive image.
