[0047]
FIG. 7 is a flowchart showing a flow of operations in the photographing system shown in FIG.
[0048]
When a power switch (not shown) provided on the grip 4 of the photographing control system 1 is turned on, the processing shown in FIG. 7 is executed until the power switch is turned off.
[0049]
First, the grip 4 is reset in step M1, and then the process proceeds to step M2.
[0050]
In step M2, it is determined whether either the electronic camera unit 3 or the compact camera unit 2 is combined with the grip 4.
[0051]
If it is determined in step M2 that none of them are combined, step M2 is repeated.
[0052]
If it is determined in step M2 that any one of them is combined, the process proceeds to step M3.
[0053]
In step M3, it is determined whether or not the unit combined is the compact camera unit 2.
[0054]
If it is determined in step M3 that the compact camera unit 2 is not combined, the electronic camera unit 3 is the only unit combined with the grip 4, and the process proceeds to step M4.
[0055]
Here, since the subroutine “electronic camera unit processing” executed in step M4 is irrelevant to the present embodiment, details will be described later.
[0056]
If it is determined in step M3 that the compact camera unit 2 is combined, the process proceeds to step M5.
[0057]
In step M5, it is determined whether or not the electronic camera unit 3 is combined.
[0058]
When it is determined in step M5 that the electronic camera unit 3 is not combined, only the compact camera unit 2 is combined with the grip 4, and the process proceeds to step M6.
[0059]
Here, since the subroutine “camera unit processing” executed in step M6 is also irrelevant to the present embodiment, details will be described later.
[0060]
If it is determined in step M5 that the electronic camera unit 3 is also combined, it means that both the electronic camera unit 3 and the compact camera unit 2 are combined in the grip 4, and the process proceeds to step M7, where subroutine ' Execute electronic camera / camera unit processing.
[0061]
In the present embodiment, this subroutine “electronic camera / camera unit processing” is executed.
[0062]
FIG. 8 is a flowchart of the subroutine “electronic camera / camera unit processing”.
[0063]
First, the grip 4 resets the combined electronic camera unit 3 in step A1. Then, it progresses to step A2.
[0064]
In step A2, a drive instruction for the CCD image sensor 32 is sent from the system controller 46 of the grip 4 to the CCD driver 32a. As a result, the CCD image sensor 32 outputs an image signal representing the subject image formed on the image sensor. Then, it progresses to step A3.
[0065]
Here, as will be described with reference to FIG. 6, the image signal output by driving the CCD image sensor 32 is converted into image data by the A / D conversion circuit 34 and then sent to the grip 4. In the image data processing circuit 400 of the grip 4 that receives this image data, processing according to an instruction from the system controller 46 is performed on the image data. When this processing is completed, the processed image data is sent to the D / A conversion circuit 401 and converted into an image signal, and then input to the LCD driver 49a. Thereafter, the processed image is displayed on the LCD 49.
[0066]
However, since the grip 4 is immediately after being reset at the stage of step A3 shown in FIG. 8, the image data processing circuit 400 performs a process according to the initial setting stored in the system controller 46 in accordance with an instruction from the system controller 46. The display on the LCD panel 49 of the image represented by the image data that has been performed on the image data and processed according to the initial setting is performed in step A3. Then, it progresses to step A4.
[0067]
In step A4, it is determined whether or not a zoom operation has been performed on a zoom switch (not shown) provided in the grip 4.
[0068]
If it is determined in step A4 that the zoom operation has not been performed, the process proceeds to step A8.
[0069]
If it is determined in step A4 that the zoom operation has been performed, the process proceeds to step A5.
[0070]
In step A5, it is determined whether the zoom operation is zoom-up or zoom-down, and a signal representing the determination result is sent from the system controller 46 of the grip 4 to the compact camera unit 2. Then, it progresses to step A6.
[0071]
The compact camera unit 2 performs the extension of the lens barrel or the collapse of the lens barrel in step A6 according to the signal representing the determination result. Then, it progresses to step A7.
[0072]
Here, in the image data processing circuit 400 of the grip 4, as described above, the image data sent from the electronic camera unit 3 is processed according to the instruction of the system controller 46. In step A4, the zoom operation is performed. As a result, the system controller 46 instructs the image data processing circuit 400 to perform processing according to the contents of the zoom operation, not the initial setting.
[0073]
The image data processed in accordance with this instruction is converted into an image signal by the D / A conversion circuit 401 and input to the LCD driver 49a, and an image represented by this image signal is displayed on the LCD panel 49 in step A7. Is called. Thereafter, the process proceeds to Step A8.
[0074]
In step A8, it is determined whether or not the shutter button 43 has been pressed.
[0075]
If it is determined in step A8 that the shutter button 43 has not been pressed, the process returns to step A3.
[0076]
If it is determined in step A8 that the shutter button 43 has been pressed, the process proceeds to step A9.
[0077]
When the shutter button 43 is pressed, the system controller 46 of the grip 4 issues a shooting instruction on the loaded photographic film to the compact camera unit 2 in step A9. Thus, in the compact camera unit 2, a shutter mechanism (not shown) is opened and closed to take a picture. Then, it progresses to step A10.
[0078]
As the shutter button 43 is pressed, the system controller 46 receives the image data from the image data processing circuit 400 at the timing of the pressing, and records the image data in the image memory 48 in step A10. Thereafter, the subroutine is exited and the process returns to step M2.
[0079]
As described above, in the photographing system 1 according to the first embodiment, the grip 4 can control the photographing function of the electronic camera unit 3 and the compact camera unit 2 combined with itself. Therefore, according to this photographing system 1, since the subject can be photographed with an electronic camera and a compact camera loaded with a roll-shaped photographic film, the photographed image can be edited or a printed photograph with good image quality can be obtained. Obtainable.
