Abstract

PROBLEM TO BE SOLVED: To obtain a camera by which photographing timing is not missed, which does not require large-scale system and which is prevented from receiving erroneous satellite information by inhibiting the reception of position survey information from a satellite when the specified operation of the camera is performed. SOLUTION: A position survey mode setting switch 4 sets a position survey mode in which position survey is performed by using a position survey means mounted on a position survey part 13 and the position survey information is recorded on film when photographed. The part 13 receives radio wave from a GPS satellite and develops the signal into the information, analyzes the necessary information, deduces latitude, longitude and altitude information, calculates positional information from the deduced information and transfers it to a control part 7. When photographing operation is started in the midst of position survey, the position survey is interrupted and photographing is prioritized. In the case of periodically performed charge, the position survey is prioritized. Thus, the photographing timing is not missed and further the position survey information is periodically updated, so that the camera excellent in handleability is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera for recording positioning information, and more particularly to a camera capable of receiving positioning information transmitted from a satellite and recording positioning information based on the received signal on a recording medium. It is about.

[0002]

2. Description of the Related Art In recent years, among cameras using a film having a magnetic recording section for recording photographing information, cameras capable of recording positioning information indicating a photographing position in the magnetic recording section have been developed.

[0003] For example, Japanese Patent Application Laid-Open No. 6-67282 discloses a CPU and a GPS (Global Position).
Positioning means for performing positioning by receiving position information via a system such as a ping system, and reception state determining means for determining whether or not the position information has been received, that is, whether or not positioning has been performed. A position information recording device including a storage unit for storing positioning information and a magnetic recording unit for recording on a magnetic recording unit of a film is disclosed. Then, the positioning information stored in the storage means is read and recorded.

[0004] Japanese Patent Application Laid-Open No. 7-84308 discloses that
There is disclosed a technique in which a camera does not have a system for receiving positioning information from a GPS satellite, and once received by a relay station, transmits positioning information, and receives information from the relay station by the camera.

[0005]

However, according to the technique described in Japanese Patent Application Laid-Open No. 6-67282, if a long time elapses without receiving the positioning information and the apparatus moves during that time, an incorrect positioning is performed. There is a risk of being recorded with information.

In addition, the technology described in Japanese Patent Application Laid-Open No. 7-84308 has a problem that a relay station must be set up in order to obtain positioning information, which requires a large-scale system. are doing.

On the other hand, if the flash capacitor is charged after flash shooting, oscillation noise during charging is superimposed inside the camera circuit, or a large amount of current flows from the power supply to the charging circuit immediately after the start of charging. There is a phenomenon that the power supply of the entire circuit becomes unstable.

Also, depending on the circuit configuration of the camera, the charge of the strobe capacitor is lost due to leakage, so that the camera is charged intermittently when the camera is in a shooting standby state so as to maintain a charging voltage so as not to miss the shooting timing. There is also.

Further, since the positioning information of the photographing place needs to be constantly updated in consideration of the fact that the photographer moves, it is necessary to periodically receive a signal from a satellite. If a weak radio wave from the satellite is received by the small antenna inside the camera during the above charging, the signal from the satellite may be erroneously received due to the influence of noise or unstable power supply. It was lacking in sex.

The present invention has been made in view of the above situation, and provides a camera which does not miss the photographing timing and does not receive erroneous satellite information without requiring a large-scale system. With the goal.

[0011]

That is, the present invention relates to a camera capable of receiving positioning information transmitted from a satellite and recording positioning information based on the received signal on a recording medium.
During the specific operation of the camera, reception of positioning information from the satellite is prohibited.

According to the present invention, there is provided a camera capable of receiving positioning information transmitted from a satellite and recording positioning information based on the received signal on a recording medium. It is characterized in that periodic replenishment charging of the strobe main capacitor is prohibited.

According to the camera of the present invention, the positioning information transmitted from the satellite is received, and the positioning information based on the received signal can be recorded on the recording medium. Reception of the positioning information is prohibited.

In the camera according to the present invention, positioning information transmitted from a satellite is received, and positioning information based on the received signal can be recorded on a recording medium. When the positioning information is received from the satellite, the supplementary charging of the strobe main capacitor, which is performed periodically, is prohibited.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a camera according to a first embodiment of the present invention.

In FIG. 1, a power switch 1 for turning on / off a power supply of a camera, a first release switch (1R switch) 2 which is turned on when a shutter release button (not shown) is half-pressed, and the shutter release A second release switch (2R switch) 3, which is turned on when the button is fully pressed, a positioning mode setting switch 4, a back cover switch (BK switch) 5, and a forced rewind switch (RWM switch) 6 are connected to the control unit 7. Have been.

The positioning mode setting switch 4 is a switch for setting a positioning mode in which positioning is performed using positioning means mounted on the camera and positioning information is recorded on a film at the time of photographing. Each time the positioning mode setting switch 4 is pressed, the positioning mode is repeatedly turned on and off.

The back cover switch 5 is a switch that is turned on and off by opening and closing a cartridge cover that opens and closes to load a film into the camera. The back cover switch 5 turns on when the cartridge cover is opened, and turns off when the cartridge cover is closed.

Further, the forced rewind switch 6 is a switch for forcibly rewinding the film being photographed into the film cartridge. When the forced rewind switch 6 is turned on, the camera performs control to rewind the film.

The control section 7 is control means composed of a one-chip microcomputer or the like, and controls the operation of the entire camera. The control unit 7 includes a strobe light emitting unit 8, a charging unit 9, a timer 2 unit 10, an exposure unit 11, a recording unit 12, a positioning unit 13,
The timer 1 unit 14 and the storage unit 15 are connected.

The strobe light emitting section 8 is a strobe light emitting means which is an artificial light source for illuminating a subject at the time of photographing, and includes a light emitting tube, a light emitting circuit and a main condenser for light emission.

The charging section 9 is a charging means comprising a charging circuit for charging the main capacitor. The charging voltage is input to the control unit 7, and the control unit 7 outputs a control signal for charging the charging unit 9 depending on whether the charging voltage is equal to or higher than a predetermined value.

After the main capacitor has been charged once by the charging unit 9, the timer 2 unit 10 reduces the charging voltage due to its own current leak path, and fails to emit strobe light at the time of shooting, so that a chance of shooting is missed. This is a timer means for so-called supplementary charging, in which the charging voltage is periodically monitored in order to avoid charging, and charging is performed as necessary.

The exposing unit 11 is an exposing unit for exposing the film, and the recording unit 12 is a recording unit for recording photographing information and positioning information on the film.
The positioning unit 13 receives a radio wave from the GPS satellite, develops the signal into information, analyzes necessary information,
It is a positioning means for calculating latitude, longitude and altitude information and calculating position information therefrom. The positioning unit 13 includes an antenna, an analog processing unit, and a digital operation unit. The positioning unit 13 receives a radio wave from a GPS satellite according to a control signal from the control unit 7 and transfers position information to the control unit 7.

The timer 1 section 14 is a timer means for periodically performing positioning when the positioning mode is turned on by the positioning mode setting switch 4. In addition, the storage unit 15 includes a nonvolatile memory (for example, EEPROM
M), and stores, in addition to information indicating the camera adjustment value, the number of shot frames, and the state of the camera, positioning cycle time information, charging voltage detection cycle time information, and the latest positioning information.

Next, the processing operation of the control unit 7 of the camera according to the first embodiment of the present invention will be described with reference to the flowcharts of FIGS. First, when the power switch 1 is turned on, initial setting is performed by the control unit 7 in step S1. For example, in addition to information indicating the adjustment value of the camera, the number of shot frames, and the state of the camera from the storage unit 15, positioning cycle time information, charging voltage detection cycle time information, and the latest positioning information are read. (Hereinafter, abbreviated as “microcomputer”) is developed in a memory (not shown) inside the control unit 7.

Next, at step S2, the positioning mode is turned off (in the actual processing inside the microcomputer, it is determined whether the positioning mode flag is "1" or "0". In this case, the flag is set to "0". ").

Next, in step S3, the control section 7 determines whether or not the positioning mode setting switch 4 has been turned on. Here, when turned on, the process proceeds to step S4,
On the other hand, when it is off, the process proceeds to step S14.

In step S4, a process for inverting the positioning mode is performed in order to perform an alternate process of the positioning mode setting switch 4. That is, if the positioning mode is off, the process proceeds to step S7, and the positioning mode is turned on. Then, in order to perform the positioning periodically, the timer 1 is reset and started in step S8. Completion of timer 1 timer
This is possible by detecting the overflow of This overflow is enabled by detecting the setting and reset of the overflow flag inside the microcomputer.

By resetting, the overflow flag of the timer 1 is cleared at the same time. For example,
If the positioning is performed every two minutes, a value that overflows in two minutes is set in the timer 1.
In this case, the value set in the timer 1 is 2 minutes,
Since this value is stored in the rewritable nonvolatile memory, it is possible to change this cycle under various conditions.

For example, in a system that travels a long distance in a short time, it is better to set the cycle to about 30 seconds to about 5 minutes. When it is assumed that the device is used in a limited area such as an amusement park, the current consumption of the circuit system is taken into consideration.
In some cases, it is better to set the cycle to about 30 minutes.
It is necessary to optimize the cycle depending on the usage situation. Since this cycle is stored in the storage unit 15, it can be optimized at the time of shipment from a factory or at a service center or the like according to the user's preference, depending on the use situation.

In step S9, the receiving circuit is turned on to receive the satellite information, and the reception of the positioning information is started. Next, in step S10, it is determined whether the reception of the positioning information has been completed, and it is determined that the reception has been completed with a predetermined number of data. Here, if not completed, the process returns to step S9 and the process is repeated.

On the other hand, if the reception has been completed in step S10, the process proceeds to step S11, where the positioning information is analyzed and converted into position information. Then, the converted position information is developed on a memory (RAM) inside the control unit 7 in step S12. Further, the power supply is shut off, for example, when the battery is detached from the battery section due to some impact during the operation of the camera, or the battery is pulled out, and the RA is disconnected.
In consideration of the fact that the contents of M are lost or destroyed, the position data is also stored in the nonvolatile memory (EEPROM) in step S13.

After that, the routine goes to Step S14. On the other hand, if the positioning mode is on in step S4, the process proceeds to step S5, and the positioning mode is turned off. Thereafter, in step S6, the timer 1 for periodically performing the positioning is stopped. this is,
This is because an overflow of the timer 1 is detected and control is performed, so that a malfunction does not occur later. Thereafter, the process proceeds to step S14.

Further, if the positioning mode setting switch 10 is off in step S3, the process proceeds to step S14. In step S14, it is determined whether the positioning mode is on or off. If it is ON, step S
The process of starting the positioning after 15 is performed, and if it is off, the process proceeds to the processes after step S26.

In step S15, the occurrence of an overflow of the timer 1 for performing the positioning periodically is detected by monitoring the overflow flag. Here, if the overflow of the timer 1 is detected, the process proceeds to step S16, and if the overflow is not detected, the process proceeds to step S26.

In step S16, the timer 1 is reset and restarted. This corresponds to step S described above.
8, the description is omitted. Next, in step S17, the receiving circuit is turned on to receive the satellite information, and the reception of the positioning information is started. Then, during the reception of the positioning information, when the operation shifts to the photographing operation, when the opening / closing of the cartridge lid is detected, or when the RWM switch 6 is pressed, a process of prioritizing the photographing operation is performed.

That is, in step S18, it is determined whether or not the 1R switch 2 has been turned on. If the switch has been turned on, the flow shifts to step S21 to interrupt the positioning reception.
On the other hand, if the 1R switch 2 has not been turned on, the process proceeds to step S19.

In step S19, it is detected that the cartridge lid has been opened to load the cartridge.
That is, it is determined whether the BK switch 5 has changed. When the change of the BK switch 5 is determined, it is known that the cartridge lid is open or closed, so that the process proceeds to step S21 and the positioning reception is interrupted. On the other hand, if there is no change in the BK switch 5, the process proceeds to step S20.

In step S20, it is further detected whether or not the RWM switch 6 has been turned on.
Since it is necessary to rewind the film, the flow shifts to step S21 to interrupt the positioning reception. On the other hand, RWM switch 6
If is not turned on, the process proceeds to step S22.

As described above, the above steps S18 to S21
In this case, when the switch changes, the reception of the positioning information is interrupted. By interrupting the reception of the positioning information, it is possible to execute an operation with a good response to an instruction or the like from the photographer via the switch. As a result, the photographing is not delayed.

Next, in step S22, it is determined whether the reception of the positioning information has been completed, and it is determined that the reception has been completed with a predetermined number of data. Here, if not completed, the process returns to step S17 and the process is repeated. On the other hand, if the reception has been completed, the process proceeds to step S23, where the positioning information is analyzed and converted into position information. Then, the converted position information is developed on a memory (RAM) inside the control unit 7 in step S24.

Further, in step S25, similarly to step S13 described above, the position data is also stored in a non-volatile memory (EEPROM) in consideration of the fact that power is cut off during the operation of the camera. Thereafter, the process proceeds to step S26.

In step S26, step S14 is performed.
When the positioning mode is off in step S15, when the overflow of the timer 1 is not detected in step S15, the processing shifts from step S25 or step S21.

In steps S26 to S32, it is periodically checked that the charged voltage of the main capacitor for flash light emission, which has been charged once, gradually decreases due to leakage in the circuit, and is recharged at any time. This is a process for setting a state in which shooting is possible.

First, at step S26, an overflow of the timer 2 for measuring the charging cycle is detected. Here, if an overflow of the timer 2 is detected, the process proceeds to step S27, and if not, the process proceeds to step S33.

In step S27, first, the overflow flag of the timer 2 is cleared, the cycle for detecting the charging voltage is set in the timer 2 again, and the timer operation is restarted. In the first embodiment, the cycle for detecting the charging voltage is set to about 5 to 10 minutes. Although this period is set to 5 minutes in the first embodiment, since this value is stored in a rewritable nonvolatile memory, the period can be changed according to various conditions.

Next, in step S28, the charging unit 9 starts charging the main capacitor inside the strobe light emitting unit 8. Then, when the timing at which the positioning is performed during the periodic charging is performed, a process of giving priority to the positioning is performed.

First, in step S29, it is determined whether the mode is the positioning mode. If the mode is the positioning mode, the process proceeds to step S30. If the mode is not the positioning mode, the process proceeds to step S30.
Move to 31.

In step S30, it is determined whether or not the timing for positioning has occurred, so that an overflow of the timer 1 is detected. When the overflow of the timer 1 has occurred, the charging is immediately stopped, and the process proceeds to step S32 to execute the positioning, and the charging is stopped. On the other hand, if the timer 1 has not overflown, the flow shifts to step S31.

In step S31, the charging voltage is checked. Here, it is determined whether or not a predetermined charging voltage has been reached, and if so, the process proceeds to step S32 and charging is stopped. On the other hand, if the charging voltage has not reached the predetermined voltage, the process returns to step S28 and the process of continuing charging is repeated.

In step S32, charging is stopped, and thereafter, the process proceeds to step S33. Step S28 and above
In S32, if the timing of receiving the positioning information conflicts during the periodic replenishment of the main capacitor, the replenishment is stopped. By stopping charging, the influence of oscillation noise and unstable power supply voltage is prevented, and highly reliable positioning information is received. Further, since positioning is prioritized over supplementary charging having an auxiliary role, missed satellite information can be prevented.

Steps S33 to S34 are performed when the cartridge is loaded and the cartridge lid is closed. First, in step S33, it is detected whether the BK switch 5 has changed from on to off. By detecting the change of the BK switch 5 from on to off,
The change from the opening to the closing of the cartridge lid is detected. When the change of the BK switch 5 from on to off is detected, the idle feeding operation of the film is executed in step S34 in order to make the loaded film cartridge ready for photographing. On the other hand, when the BK switch 5 does not change from on to off, the process proceeds to step S35.

In step S35, it is detected whether or not the RWM switch 6 has been turned on. If it is detected that the RWM switch 6 is turned on, the loaded film is rewound in step S36.
On the other hand, if the RWM switch 6 is off, the process moves to step S37.

In steps S33 to S36,
The reception of the positioning information is prohibited (that is, the step of “positioning information reception” is not provided in the flowchart). In this way, by prohibiting the reception of the positioning information, it is possible to prevent the influence of the oscillation noise and the unstable power supply voltage at the time of driving the motor, and to prevent the positioning with low reliability.

Next, a photographing preparation operation and a photographing operation in steps S37 to S51 will be described. In step S37, it is determined whether or not the 1R switch 2 is ON, thereby determining whether or not the shutter release button is half-pressed. Here, if the 1R switch 2 is off, the process returns to step S3 and the subsequent processes are repeated. On the other hand, if the 1R switch 2 is on, the process moves to step S38.

In step S38, the 1R switch 2
Only once when is turned on, the process proceeds to step S39 to perform distance measurement and photometry, and then proceeds to step S40. On the other hand, if the 1R switch 2 remains on, the process proceeds to step S40.

In step S40, it is detected whether the 2R switch 3 is on. If it is ON, the flow shifts to step S41 to execute the shutter release operation. On the other hand, if it is off, the process returns to step S37 and the subsequent processing operations are repeated.

When the steps S37 to S40 are repeated, the 1R switch 2 is turned on and the 2R switch 3
Is turned off, which is equivalent to the case where shooting is to be performed. In this case, the reception of the positioning information is prohibited (that is, the step of “positioning information reception” is not provided in the flowchart). Since the step of “positioning information reception” is not provided, the detection interval of the 2R switch 3 can be shortened, and the photographing operation is not delayed.

In step S41, the above-mentioned step S39 is performed.
The shooting lens is extended so as to focus on the subject based on the information obtained by the distance measurement executed in step (1). Next, step S42
, The shutter is controlled to take a picture.

Then, in step S43, after the photographing is completed, the film mechanism (not shown) is controlled by the control section 7, and the feeding of the film is started. In step S44, the positioning mode is determined. Here, if the positioning mode is on, the process proceeds to step S45, and if it is off, the process proceeds to step S46. In step S45, the recording unit 12 controls the C2 track (not shown) on the film.
The positioning information stored in the storage unit 15 is recorded.

Further, in step S46, the control section 7 records the photographing information on the recording section 12 and the C1 track on the film. Subsequently, in step S47, the control section 7 determines whether or not the feeding of the film has been completed for one frame. If the recording has not been completed, the flow returns to step S44 to continue the recording. When the feeding of one frame has been completed, the flow shifts to step S48.

Next, if the strobe light is emitted at the time of exposure in step S42, the main capacitor of the strobe light emitting unit 8 needs to be charged.
At 51, charging is performed.

That is, time lapse is performed in step S48, and it is determined in step S49 whether charging is completed. Here, if not completed, the above step S4
Returning to step 8, charging is continued. On the other hand, if charging has been completed, charging is stopped in step S50, and
At 51, the timer 2 is reset and restarted.
This is the same process as step S8 described above, and a description thereof will be omitted.

In steps S48 to S50,
Receiving positioning information is prohibited during charging of the main capacitor when a strobe light is emitted at the time of exposure (that is, the step of “positioning information reception” is not provided in the flowchart). By prohibiting the reception of the positioning information, it is possible to prevent the influence of the oscillation noise and the unstable power supply voltage and perform the highly reliable positioning. In addition, since the charging required for shooting is prioritized over positioning, preparation for the next shooting can be completed quickly.

Thereafter, the state of the 1R switch 2 is determined in step S52.
Return to step S3 if it is off. Further, when the 2R switch 3 is kept pressed, transfer becomes possible.

Here, the above steps S37 → S52 → S
Repetition of the steps from 37 to S52... Is a state of continuous shooting. As described above, during continuous shooting, reception of positioning information is prohibited (that is, the step of “positioning information reception” is not provided in the flowchart). Since the step of “positioning information reception” is not provided, the interval between continuous shootings can be increased, and continuous shooting can be performed at short intervals.

As described above, when the photographing operation is started during the positioning, the positioning is interrupted, the photographing is prioritized, and in the charging performed periodically, the positioning is prioritized so that the photographing timing is missed. However, since the positioning information is updated periodically, it is possible to provide an easy-to-use camera.

In the first embodiment described above, a camera having a silver halide film has been described. However, the present invention is not limited to this, and is applied to, for example, an electronic still camera that electronically records images and positioning information in a memory.

37 to S41 and steps S48 to S52 are the same, and a description thereof will be omitted.

Next, the processing of the control unit 7 will be described with reference to the flowcharts shown in FIGS. Step S

The image signal obtained by digitizing the image information on the image sensor is recorded in the image / positioning information recording medium 19 by the image / positioning information recording unit 18 in step S97.

Next, in step S98, after the photographing in which the photographed image is recorded on the recording medium 19, the control unit 7 detects the state of the positioning mode flag. here,
If the positioning mode flag is on, the process proceeds to step S99, and if it is off, the process proceeds to step S100.

In step S99, the image / positioning information recording unit 18 records the positioning information corresponding to the positioning information identification number selected by the positioning mode setting switch 4 on the recording medium 19 in association with the image information. .

On the other hand, when the positioning recording mode flag is off in step S98, the positioning information is not recorded, and as a result, only the image information is recorded.
Subsequently, in step S100, the address of the recording area of the recording medium 19 for recording the image / positioning information is updated by the control unit 7 for the next photographing, and step S101 is performed.
