2. Description of the Related Art In a conventional electronic image pickup camera, an image signal picked up and generated by an image pickup device is converted into a predetermined compressed / compressed data and then stored in a semiconductor memory device arranged inside the camera. However, since the semiconductor memory element is used, the storage capacity of image data is limited.

Further, since the semiconductor memory element is expensive, a plurality of semiconductor elements are not always held, and image data stored in the semiconductor memory element is externally stored in a personal computer (hereinafter referred to as a personal computer) or the like. It is being transferred to a storage device and stored.

When the image data stored in the semiconductor memory device of this electronic image pickup camera (hereinafter referred to as an electronic camera) is transferred to a personal computer, the electronic camera and the personal computer are connected using a data transmission connection line. The electronic camera is driven and controlled by the personal computer to read the image data stored in the semiconductor storage element and store it in the personal computer storage medium.

When transferring image data from the electronic camera to the personal computer, it is necessary that the electronic camera and the personal computer exist within a range where they can be connected by a data transmission connection line. If you use an electronic camera away from your computer and the image data taken by that electronic camera exceeds the storage capacity of the semiconductor memory device, you can shoot with the electronic camera unless you replace it with a new semiconductor memory device. Disappear.

Therefore, there is a method of transferring image data of an electronic camera in which the image data taken by the electronic camera is transferred to the personal computer by using a telephone line even if the place where the electronic camera is used and the personal computer for storing and saving the image data are distant from each other.

When a power switch (not shown) of the input means 5 is turned on, drive power is supplied from the power supply means 7 to the image pickup means 1, the CPU 2, the display means 3 and the first wireless communication means 6 in step S1. Is supplied and C
PU2, based on the input of the power switch ON, drives the photographing optical system (not shown) from the retracted position of the main body of the electronic image pickup camera to the wide-angle end position where the image can be picked up,
An initializing operation is performed so that the electronic image pickup camera can take an image.

When the initializing operation in step S1 is completed, in step S2, the CPU 2 starts a timer function (not shown) built in the CPU 2 and measures the elapsed time. This timer sets the electronic image pickup camera to the power saving mode in order to save the drive power supplied from the power supply means 7 when the input means 5 is not operated for any switch within a predetermined time after the timer is started. Therefore, when any switch of the input means 5 is operated, the electronic image pickup camera is brought into a standby state in which the electronic image pickup camera can be quickly returned to the image pickup ready state.

Upon completion of the timer start in step S2, the CPU 2 checks the charge of a power supply capacitor for strobe light emission (not shown).
If a charge check function (not shown) is driven and the result of the check by the charge check function is that the charge charge of the charging capacitor is less than a predetermined charge, the charge function (not shown) is driven to perform the charging operation. To do.

In step S3, when the charge stored in the charging capacitor has a predetermined value, or when the charging function is driven to charge the charging capacitor to a predetermined value,
In step S4, the CPU 2 determines whether a zoom up or down switch (not shown) provided in the input means 5 has been operated.

When it is determined in step S4 that the zoom up or down switch has been operated, the CP
U2 drives and controls a zoom drive function (not shown) to drive the photographing optical system to zoom up or down in step S5. That is, when the zoom up switch is turned on, the zoom drive function is driven so as to extend the photographing optical system from the wide-angle end side toward the telephoto end side, and when the zoom down switch is turned on, the photographing optical system is moved to the telephoto side. The zoom drive function is driven so that the zoom drive function is retracted from the end side toward the wide-angle end side.

When it is determined in step S4 that neither the zoom up switch nor the down switch is operated, or when the zoom drive in step S5 is completed, the release switch of the input means 5 is turned on in step S6. Determine whether or not.

This release switch is a switch that can be operated in two steps. When the release switch is half pressed, the first release switch (1
R) is turned on, and the second release switch (2R) is turned on in the fully pressed state. When the first release switch (1R) in the half-pressed state is turned on, the CPU 2 drives and controls a photometric function (not shown) for measuring the subject brightness and a distance measuring function for measuring the distance to the subject. When the second release switch (2R) in the fully pressed state is turned on, C
The PU 2 adjusts the focus of a photographing optical system (not shown) on the basis of the result of the distance measurement, sets the aperture value of the photographing optical system on the basis of the result of the photometry, and electronic shutter time of the image pickup device of the image pickup means 1. Setting, and driving the image pickup means 1,
Generation and drive of an electronic image signal and image data of a subject image exposed on the image sensor are performed.

If it is determined in step S4 that the first release switch (1R) is turned on, step S7
Then, the CPU 2 drives a photometric function (not shown) to measure and drive the subject brightness. A known photometric measuring method is used for the photometric function, and a method of calculating a brightness value from a subject image signal photoelectrically converted by the image sensor of the image pickup means 1 and a photocurrent generated by the subject light incident on the photometric element are used. There is a method of calculating the subject brightness value based on.

When the photometric operation in step S7 is completed, in step S8, the CPU 2 drives a known distance measuring function for measuring the distance to a subject (not shown),
Measure the distance to the subject. As the distance measuring function, a triangulation method, which is a known distance measuring method, is mainly used.

The triangulation method includes a passive method and an active method. The passive method is configured to have a pair of line sensors that separate and receive light from a subject and convert it into respective subject image signals. ing. Further, an auxiliary light source such as a strobe that illuminates the subject with illumination light when the subject has low brightness or contrast may be provided.

In the active system, the infrared light emitting element for projecting the infrared light beam toward the object, the infrared light emitting element and the infrared light emitting element are arranged with a base length, and the object is irradiated with the infrared light beam. And a position detecting element for receiving the reflected light from.

When the distance measurement by triangulation such as the hybrid method in which either the passive method or the active method or the both methods are combined is completed in step S8, the CPU 2 causes the second release switch to operate in step S9. It is determined whether (2R) is turned on. When it is determined that the second release switch (2R) is off, the CPU 2
At step S10, the first release switch (1
R) is turned on, and if it is turned on, the process returns to step S9 and the second release switch (2R) is turned on again. If it is determined that the first release (1R) is off, step S17 and subsequent steps are executed.

When it is determined in step S9 that the second release switch (2R) is on, the CPU2
In step S11, the focus adjusting function of the photographing optical system (not shown) is driven based on the distance measurement value measured in step S8 to adjust the photographing optical system to the focus position.

Next, in step S12, the CPU 2 drives and controls the image pickup means 1, and based on the photometric value measured in step S7, the exposure time of the image pickup element of the image pickup means 1, that is, the electronic shutter. Drive control is performed to photoelectrically convert the subject image exposed on the image sensor to generate an analog subject image signal. When it is determined that the subject is dark as a result of the photometry in step S7, the subject may be exposed by stroboscopic light emission and strobe illumination. This analog subject image signal is converted into a digital subject image signal and is also converted into predetermined compressed digital image data. This compressed digital image data is the image signal compression method JPE.
The G method or the like is used.

When the image pickup operation in step S12 is completed, in step S13, the CPU 2 converts the compressed digital image data generated by the image pickup means 1 into a digital image signal, and the digital image signal is converted into the digital image signal. It is supplied to the display means 3 to display the image of the imaged subject image.

The image of the picked-up subject image is displayed on the display means 3 in step S13, and the CPU 2
The built-in timer is started to measure the image display start time on the display means 3.

When the image display by the display means 3 in step S13 is started, the CPU 2 operates in step S14.
Controls to store the digital compressed image data generated by the image pickup means 1 in the storage means 4. When the image data is stored in the storage means 4, the address data for storing and storing the image data in the storage means 4 and the code data for erasing the stored image data or for not erasing the image data are stored together.

When the storage of the image data in the storage means 4 in step S14 is completed, the CPU in step S15.
2 determines the elapsed time of the timer started when the captured image is displayed on the display unit 3 in step S13, and displays the display time until the display of the captured image displayed on the display unit 3 elapses a predetermined time. Judgment is made and the display means 3
When the display of the captured image of is elapsed for a predetermined time, step S1
In step 6, the CPU 2 controls to stop the display drive of the captured image on the display means 3, and step S17 and subsequent steps are executed.

Step S6 or step S10
Then, when it is determined that the first release switch (1R) is off, or when the display of the captured image on the display means 3 is terminated in step S16, the CPU 2 in step S17 causes the power switch to switch It is determined whether it is in the ON state at the time of initialization in step S1. When it is confirmed that the power switch is turned on in step S17, the CPU 2 determines in step S18 whether or not a predetermined time set in advance has elapsed since the timer was started in step S2. If not, the process returns to step S3, the strobe charging check and subsequent steps are executed again, and the imaging operation of subject imaging that is continuously performed is executed.

When it is determined in step S17 that the power switch is off, or when it is determined in step S18 that a preset predetermined time has elapsed from the timer start, the CPI 2 causes the electronic image pickup in step S19. Performs camera termination processing.

In the ending process of step S19, the photographing optical system is retracted to the retracted position, and the power supply means 7 is used.
To stop the driving power supply to the image pickup means 1 and the display means 3 and read at least the image data stored in the storage means 4 by the CPU 2 and the read image data as the first image data. Only the power supply for driving the function of transmitting to the external storage means 8 by using the wireless communication means 6 is performed.

When the end processing of the step S19 is completed, the CPU 2 determines whether or not the image data stored in the storage means 4 is automatically transferred to the external storage means 8 in step S20. The automatic transfer determination operation in step S20 will be described later.

When automatic transfer is to be performed, the CPU 2 reads out the image data stored in the storage means 4 in step S21, drives and controls the first wireless communication means 6, and executes the external storage. The wireless communication is performed with the second wireless communication unit 9 of the unit 8 to transfer the image data. The details of the image data transfer operation in step S21 will be described later.

It is determined in step S20 that the image data is not automatically transferred, or in step S2.
When the automatic transfer of the image data of No. 1 is completed, step S2
In step 2, the electronic image pickup camera is brought into a Halt state.

This Halt state means that the first wireless communication means 6 can receive the image data transfer request signal from the second wireless communication means 9 and the image is sent from the second wireless communication means 9. When the data transfer request signal is received, the CPU 2 reads the image data from the storage means 4,
Further, it is in a standby state in which it is possible to return to the operation of controlling the drive of the first wireless communication means 6 to transfer the image data.

In the Halt state of step S22, the external storage means 8 drives the second wireless communication means 9 to transmit an image data transfer request signal, and the first wireless communication means 6 transfers image data. When the request signal is received and the received information is transmitted to the CPU 2, step S23
Then, the CPU 2 determines whether or not the first wireless communication unit 6 has received the image data transfer request, and if it is determined that the image data transfer signal has been received, step S24.
Then, it is determined whether or not the automatic transfer is performed, and when it is determined that the automatic transfer is performed, the process returns to step S21, and the image data transfer operation is executed. This step S24 performs the same operation as that of step S20, and its details will be described later.

When the CPU 2 determines in step S23 that the image data transfer request signal from the second wireless communication means 9 is not received, the process returns to step S1 and the power switch of the electronic image pickup camera is turned off. The image capturing disabled state is set, and the initialization standby state in step S1 is set.

If it is determined in step S24 that automatic transfer is not to be performed, the process returns to step S22,
Set to Halt state.

That is, when the power switch of the electronic image pickup camera is turned on, the image pickup operation of the image data electronically picked up by the image pickup means 1 and stored in the storage means 4 in accordance with the electronic image pickup operation of steps S1 to S16 is completed. When the power switch of the electronic image pickup camera is turned off and the automatic image data transfer switch is turned on, the first wireless communication means 6 and the second wireless communication means 9 wirelessly communicate with each other, and It is automatically transferred from the imaging camera to the external storage means 8. Further, after the power switch of the electronic image pickup camera is turned off, the image data can be transferred by an image data transfer request from the external storage means 8.

Here, the above step S20 and step S
4 and 5 for the automatic transfer determination processing in 24.
Will be described with reference to.

First, as shown in FIG. 4, step S40.
The open / closed state of the battery chamber lid 10 is detected by
If is open, the battery may be removed, so in step 42 automatic transfer is prohibited (turned off). If the battery chamber lid 10 is closed, step S
In 41, automatic transfer is permitted (turned on).

On the other hand, instead of detecting the open / closed state of the battery chamber lid 10, the state of the power source may be detected as shown in FIG. That is, in step S45, it is detected whether or not the power supply voltage has dropped below a predetermined voltage, and if it has fallen, automatic transfer is prohibited (turned off) in step 47. If the voltage is higher than a predetermined voltage,
In step S46, automatic transfer is permitted (turned on).

Here, it is detected whether or not the power supply voltage has dropped below a predetermined voltage, but the invention is not limited to this, and more generally, when the power supply is below a predetermined power supply capability. It suffices to detect whether or not there is.

Further, in step S41 and step S42 of FIG. 4 or in step S46 and step S47 of FIG. 5, automatic transfer permission and prohibition are switched, but instead of the above, the first transfer is performed. The power supply to the wireless communication means 6 may be switched on / off. In this case, a means for switching the power supply state to the first wireless communication means 6 in accordance with a control command from the CPU 2 may be provided inside the power supply means 7 shown in FIG.

Next, the detailed operation of the image data transfer in step S21 will be described with reference to FIG. In step S25, the CPU 2 checks whether or not untransferred image data is stored in the storage means 4, and if it is determined that there is no untransferred image data, the CPU 2 returns to the process of FIG. If Halt and thereafter are executed and it is determined that there is untransferred image data, step S26.
Then, the CPU 2 determines whether or not the image data transfer request signal from the second wireless communication means 9 of the external storage means 8 is received by the first wireless communication means 6.

If it is determined in step S26 that the first wireless communication means 6 has not received the image data transfer request signal from the second wireless communication means 9, the CPU 2 determines in step S27 Using one wireless communication unit 6 as a master, the image data stored in the storage unit 4 is preliminarily driven to transfer the image data to the external storage unit 8 via the second wireless communication unit 9, and step S28 is performed.
Then, the first wireless communication means 8 is driven, and a request signal for wirelessly communicating with the second wireless communication means 9 is transmitted.

When the second wireless communication means 9 receives the image data transfer request signal from the first wireless communication means 6, the image data transfer request signal received by the second wireless communication means 9 is processed in response to the above. The external storage means 8 determines whether the image data transfer is acceptable or ready for acceptance. If the image data is acceptable, the external storage means 8 drives and controls the second wireless communication means 9, An image data acceptance response signal is output to the first wireless communication unit 6.

In response to the image data transmission request from the first wireless communication means 6 in the step S28, the step S
At 29, based on the drive control of the external storage means 8, the CPU 2 determines whether the image data acceptance response signal is output from the second wireless communication means 9 and is received by the first wireless communication means 6. To do.

If it is determined in step S29 that there is no response to the transmission of the image data from the external storage means 8, the process returns to the process shown in FIG. When there is a response to the transfer acceptance of step S31, steps S31 and thereafter are executed.

When it is determined in step S26 that the first wireless communication means 6 receives the image data transfer request signal from the second wireless communication means 9, the CPU 2 determines in step S30 Using the one wireless communication unit 6 as a slave, the image data stored in the storage unit 4 is transferred to the external storage unit 8 via the second wireless communication unit 9 in response to a request from the external storage unit 8. Prepare to transfer.

That is, the first and second wireless communication means 6,
9 adopts Bluetooth (registered trademark), so that both can become a master and a slave.

When the image data acceptance response is received from the external storage means 8 in the step S29, and the image data transfer preparation is completed by the image data transfer request from the external storage means 8 in the step S30, In step S31, the CPU 2 reads the untransferred image data from the storage unit 4, drives and controls the first wireless communication unit 6, and transfers the untransferred image data to Bluetooth.
The wireless signal is transmitted to the second wireless communication unit 9 as a wireless signal of (registered trademark) specifications and stored in the external storage unit 8.

Next, in step S32, the CPU 2 determines whether or not there is a transfer communication error in the untransferred image data wirelessly transmitted in step S31. This step S3
If it is determined in step 2 that there is a wireless communication error, step S
At 34, the CPU 2 re-transfers and communicates the image data in which the transfer communication error has occurred by controlling the driving of the first wireless communication means 6.

Whether or not there is a transfer communication error in the image data retransfer-communicated in step S34 is checked in step S35.
Re-determine with U2. If it is determined again that there is a transfer communication error in the determination of the transfer communication error in step S35, the CPU 2 in step S36 sets the erase prohibition of the image data in which the transfer communication error has occurred from the storage unit 4 or displays The erasure prohibition warning display or the like is set in the means 3.

If it is determined in the transfer communication error determination in steps S32 and S35 that there is no transfer communication error, the CPU 2 stores it in the storage means 4 in step S33, and transfers it in steps S31 and S34. The settings such as erasure prohibition or erasure prohibition warning display from the storage means 4 of the communicated image data are canceled.

Next, in step S37, the CPU 2 determines whether each image data stored in the storage means 4 can be automatically erased. This automatic erasing determination is made in the step S
In step 33, the settings such as erasure prohibition and erasure prohibition warning display are cancelled, and whether automatic erasure is effective,
Whether or not the erasure prohibition or the erasure prohibition warning display is set in 6 to disable the automatic erasure.

If it is determined in step S37 that the automatic erasure is valid, the CPU 2 determines in step S38 whether the transmission partner is a predetermined external storage device, and the device is a predetermined external storage device. If judged,
In step S39, the image data stored in the storage means 4 is erased. The image data to be erased is stored in the storage means 4, and the step S31 or S is executed.
In step S32 or S35, transfer communication is performed in step S34.
It is the image data for which it is determined that there is no transfer communication error in step S33, and the deletion prohibition or the deletion prohibition warning display setting is canceled in step S33.

The preset external storage device may be a unique external storage device that can be arbitrarily set and is paired with the electronic image pickup camera, or may be a telephone (mobile phone). It may be an external storage device excluding devices such as telephones, car phones, etc.), printers, mice and the like.

If it is determined in step S37 that the automatic erasure is invalid, it is stored in the storage means 4, and transfer communication is performed in step S31 or S34, and a transfer communication error occurs in step S32 or S35. The determination is made, and further, the image data for which the erasure prohibition or the erasure prohibition warning display is set in the step S36 is not erased but remains.

When it is determined in step S37 that the automatic erasure is invalid, or when it is determined that the automatic erasure is valid but it is not the predetermined external storage device in the next step S38, or the image data of the image data is determined in step S39.
