01 to determine whether or not the image data has been read (that is, whether or not image data exists in the digital camera 14). Further, the data transfer instructing means 22 c
When a captured image is read by D201, an instruction to transfer the image data obtained thereby to the external device 16 is issued.

Next, the operation of the imaging system 10 having the control configuration shown in FIG. 6 will be described with reference to the flowchart shown in FIG. The flowchart shown in FIG.
The operation of the external device 16 is performed by starting a communication program with the digital camera 14 when the external device 16 is activated.
Whether the digital camera 14 is mounted on the digital camera 20 is determined by the camera mounting determining unit 22a (step S).
1).

If this determination is affirmative, the release button 143 is turned on and the photographed image is
The data presence / absence determination means 22 determines whether or not the data has been read by
b (step S3). If this determination is affirmative, the image data obtained by reading the captured image by the CCD 201 is transmitted to the data transfer instructing means 2.
2c, the image data is directly transferred to the external device 16, and the transferred image data is received and stored in the hard disk 221 (step S5).

Thereafter, the flow shifts to step S3, and the subsequent operations are repeatedly executed. If the determination in step S1 is negative, the digital camera 14
Wait until it is set to 0. If a negative determination is made in step S3, the process proceeds to step S1 and the subsequent operations are repeatedly executed.

As described above, the photographing system 1 according to the present invention
0, the image data is not directly loaded into the flash memory 205 of the digital camera 14 but is directly loaded into the hard disk 221 of the external device 16 when shooting is performed with the digital camera 14 attached to the camera loading unit 120. Therefore, the image data is temporarily fetched into the flash memory 205 of the digital camera 14 and the image data is
5, the hard disk 221 of the external device 16
The image data obtained by the digital camera 14 can be stored in the hard disk 221 of the external device 16 easily and in a short time without the complicated step of transferring the data to the digital camera 14. Further, since the image data is not taken into the flash memory 205, the work of erasing the image data in the flash memory 205 becomes unnecessary, and
5 is easy to maintain.

Next, the operation of the imaging system 10 having the control configuration shown in FIG. 6 will be described with reference to the flowchart shown in FIG. The flowchart shown in FIG.
The operation of the digital camera 14 is performed when a main switch (not shown) of the digital camera 14 is turned ON. The external device 16 is first mounted on the digital camera 14 by mounting the digital camera 14 on the camera mounting unit 120. Is determined by the device connection determining means 20a (step S21).

If this determination is affirmative, the data presence / absence determination means 20b determines whether or not image data is stored in the flash memory 205 (step S2).
3). If this determination is affirmative, the image data stored in the flash memory 205 is transferred to the external device 16 in accordance with an instruction from the data transfer instruction means 20c based on the key operation of the keyboard 163 (step S25), and the data is subsequently erased. The image data stored in the flash memory 205 is erased according to the instruction from the instruction means 20d (step S27). Thereafter, the process proceeds to step S23, and the subsequent operations are repeatedly executed.

If a negative determination is made in step S21, whether or not the release button 143 has been turned on is determined by the switch-on determining means 20e (step S29).
If this determination is affirmative, an instruction to capture image data is issued by the data capture instruction means 20f, and shooting is performed (that is, the captured image is read by the CCD 201) (step S31). When the photographing is performed, the subject is projected on the liquid crystal display unit 145 at the same time. If the determination is negative in step S23, step S2
Move to 9.

Next, whether or not the digital camera 14 is connected to the external device 16 by being mounted on the camera mounting portion 120 is determined again by the device connection determining means 20a (step S33). If this determination is affirmative (that is, if this determination is affirmative,
This is the case where the determination is affirmative in step S21 and negative in step S23. ) Data compression instruction means 20
The compression of the image data is executed according to the instruction from g (step S35), and the compressed image data is transferred to the external device 16 according to the instruction from the data transfer instruction means 20c (step S37). Thereafter, the process proceeds to step S21, and the subsequent operations are repeatedly executed. Note that the compression in step S35 is performed at a low compression rate because the image data is stored in the large-capacity hard disk 221.

On the other hand, if the determination is negative in step S33 (that is, the case where this determination is negative is the case where the determination is negative in step S21), an instruction from the data compression instruction means 20g is issued. The image data is compressed (step S39), and the compressed image data is stored in the flash memory 205 according to an instruction from the memory storage instruction unit 20h (step S41). Thereafter, the process proceeds to step S21, and the subsequent operations are repeatedly executed. Note that the compression in step S39 is executed at a high compression rate because the image data is stored in the small-capacity flash memory 205.

As described above, the photographing system 1 according to the present invention
In the case of 0, the image data is stored in the flash memory 205 when shooting is performed in a state where the digital camera 14 is not mounted on the camera mounting unit 120. When the digital camera 14 is mounted on the camera mounting unit 120 in this state, the image data is transferred from the flash memory 205 to the hard disk 221 and thereafter the image data in the flash memory 205 is deleted. Therefore, the image data obtained by the digital camera 14 can be easily transferred to the hard disk 221 of the external device 16 and stored without requiring complicated transfer work as in the related art. Further, since the image data in the flash memory 205 is automatically deleted, maintenance of the flash memory 205 is facilitated.
