[Imaging Operation According to First Embodiment] First,
The imaging operation according to the first embodiment will be described with reference to the flowcharts of FIGS. The system control unit 22 performs the following processing according to the program stored in the memory 23. In the first embodiment, the image stabilization ON / OFF is set.
The switch 31 does not necessarily need to be provided.

When the power is turned on, the system controller 22 first initializes flags, control variables, and the like, and moves the shake correction lens 4 to the initial position (step S10).
1) The image display of the image display unit 13 is set to the OFF state (step S102). Next, it is determined whether or not the power supply unit 102 is normal (step S103). This determination is made by, for example, checking by the power supply control unit 32 whether the power supply unit 102 has a problem such as the remaining capacity of the battery of the power supply unit 102 when the digital camera 1 operates normally. As a result, when the power supply unit 102 is not normal,
A predetermined warning is displayed by image or sound using the display unit 24 (step S104), and the process returns to step S103.

On the other hand, if the power supply unit 102 is normal, it is determined whether or not the recording unit 203 is normal (step S1).
05). This determination is made by checking whether or not the state of the recording unit 203 does not particularly hinder the recording and reproduction of image data.
If is not normal, a predetermined warning is displayed by image or sound using the display unit 24 (step S104), and the process returns to step S103. If the recording unit 203 is normal, various setting states of the digital camera 1 are displayed on the display unit 24 using images and sounds (step S106).

Subsequently, the system control unit 22 checks the setting state of the image display ON / OFF switch 28 (step S107). When the image display ON / OFF switch 28 is set to ON, the image display of the image display unit 13 is turned ON. And set
The digital camera 1 is also displayed on the image display unit 13 by using images and sounds.
Are displayed (step S108), and a through display state for sequentially displaying captured image data is set (step S110), and the process proceeds to step S111.

In the through display state, the image data sequentially written to the image display memory 11 via the image pickup device 6, the A / D converter 7, the image processing unit 9, and the memory control unit 10 is stored in the memory. An electronic finder function is realized by sequentially displaying images on the image display unit 13 via the control unit 10 and the D / A converter 12.

On the other hand, the image display ON / OFF switch 28
Is set to the image display OFF, the image display of the image display unit 13 is set to the OFF state (step S1).
09), the process proceeds to step S301. In addition, image display OF
In the case of F, the photographing can be performed while confirming the photographed image using the optical finder 34 without using the electronic finder function of the image display unit 13. In this case, it is possible to reduce power consumption by the image display unit 13 and the D / A converter 12 that consume a large amount of power.

If there is no problem in the live view display, the shake detecting section 20 starts a shake detection process for detecting a shake (step S111). Then, since a shake detection signal is input from the shake detection unit 20 to the system control unit 22, the system control unit 22 starts an optical shake correction process based on the shake detection signal (step S112). This shake correction processing is performed by driving and controlling the actuator 4a by the image stabilization control unit 19 to move the shake correction lens 4 in a direction orthogonal to the optical axis direction.

Next, the switch S of the shutter switch 27
It is determined whether or not W1 is ON (step S20).
1) If the switch SW1 is in the OFF state, the process returns to step S103. On the other hand, if the switch SW1 is in the ON state, the distance measurement processing is performed by the distance measurement control unit 17 so that the focus of the focus lens 2 is focused on the subject, and the light measurement processing is performed to determine the aperture value and the shutter time (step). S202). In addition, in the photometric processing, the setting of the flash is performed if necessary. This distance measurement / photometry process will be described later in detail with reference to FIG.

Next, the switch S of the shutter switch 27
It is determined whether W2 is in the ON state (step S2).
03). As a result, if the switch SW2 is ON, the process proceeds to step S205. In step S205, the memory control unit is directly connected to the A / D converter 27 via the image sensor 6, the A / D converter 7, the image processing unit 9, the memory control unit 10, or without passing through the image processing unit 9. 10, an exposure process for writing the captured image data in the memory 14 via the memory 10, and using the memory control unit 10 (the image processing unit 9 as necessary) to read out the image data written in the memory 14. A photographing process including a developing process for performing various processes is executed. This photographing process will be described later in detail with reference to FIG.

When the photographing process is completed, the system control unit 2
2 reads out the photographed image data written in the memory 14 and reads out the image data written in the memory 14 using the memory control unit 10 (the image processing unit 9 as necessary) to perform various processes. At the same time, the compression / decompression unit 15 is used to perform a compression process of performing an image compression process according to the mode related to the setting (step S206). And interface 3
5 or 201, via the connector 36 or 202,
A recording process of writing image data to the recording unit 203 such as a memory card or a CompactFlash (registered trademark) card is executed (step S207), and the process ends.

While the image data is being written into the recording unit 203, a display such as "BUSY" is displayed on the image display unit 13 to indicate that the writing operation is being performed. In the unit 24, for example, the LED is blinked.

If it is determined in step S203 that the switch SW2 is OFF, the switch SW1 is turned off.
Is determined whether or not is ON (step S20)
4). As a result, if the switch SW1 is in the ON state,
That is, if the switch SW1 is still ON and the switch SW2 is not yet ON, the process proceeds to step S20.
Return to 3. On the other hand, if the switch SW1 is in the OFF state, that is, the switch SW1 is once turned on, but the switch SW1 is turned off without turning on the switch SW2.
If the answer is F, the process returns to step S103.

In step S107, image display ON / O
If it is determined that the FF switch 28 is set to the image display OFF, the image display of the image display unit 13 is set to the OFF state in step S109 as described above. Is determined to be in the ON state. As a result, the switch SW1
Is OFF, the process returns to step S103.

On the other hand, if the switch SW1 is ON, a shake detection process for detecting a shake by the shake detection section 20 is started (step S302). Then, since a shake detection signal is input from the shake detection unit 20 to the system control unit 22, the system control unit 22 starts an optical shake correction process based on the shake detection signal (step S30).
3). This shake correction processing is performed by moving and controlling the shake correction lens 4 in a direction orthogonal to the optical axis direction by controlling the drive of the actuator 4 a by the image stabilization control unit 19.

The following distance measurement and photometry processing (step S30)
The processes from 4) to the recording process (step S309) are as follows.
Since the processing is exactly the same as the above-described steps S202 to S207 in FIG. 3, the description is omitted here.

As described above, in the first embodiment, when it is confirmed that the image display on the image display unit 13 is ON, the shake detection and shake correction processing is started at that time, and
When the image display on the image display unit 13 is OFF, the shake detection and the shake correction process are started after the switch SW1 of the shutter switch 27 is turned ON.

In other words, in the first embodiment, when an image is displayed on the image display unit 13, the user displays the captured image, that is, the shake correction result, on the image display unit 13 before shooting. In consideration of the fact that the display can be confirmed, the shake detection and the shake correction processing are started immediately after confirming that the display is in the ON state, and when the image is not displayed on the image display unit 13, the user is required to perform the operation before photographing. Image display unit 13 in advance
Because the result of the shake correction cannot be confirmed, the processing time of the shake detection and the shake correction processing can be shortened by waiting for the switch SW1 of the shutter switch 27 to be turned on, and starting the shake detection and the shake correction processing. It is trying to save power consumption.

Therefore, even in the digital camera 1 using a battery as a power source, photography can be continued for a long time, and usability is improved.

Next, in step S202 in FIG. 3 (the same applies to step S304 in FIG. 4 and step S403 in FIG. 8), the distance measurement and measurement performed under the control of the system control unit 22 are performed.
Details of the photometric processing will be described with reference to the flowchart of FIG.

The system control unit 22 reads out the charge signal from the image pickup device 6 and sends the charge signal through the A / D converter 7 to the image processing unit 9.
The captured image data is sequentially read (step S501).
The image processing unit 9 uses the sequentially read image data.
Performs predetermined calculations necessary for TTL (through the lens) AE (auto exposure) processing, EF (flash pre-emission) processing, and AF (auto focus) processing. In each of the processes, a specific portion of the total number of photographed pixels, which is necessary, is extracted by extracting necessary portions, and the extracted portions are used for calculation. As a result, the TTL A
In each processing of E, EF, AWB, and AF, it becomes possible to perform an optimal calculation for each of different modes such as a center-weighted mode, an average mode, and an evaluation mode.

Next, the system control unit 22 uses the calculation result of the image processing unit 9 to perform AE control using the exposure control unit 18 until the exposure (AE) is determined to be appropriate (step S502). Is performed (step S503). Further, the system control unit 22 determines whether or not the flash is necessary, using the measurement data obtained by the AE control (Step S).
504). As a result, if a flash is required, the flash flag is set and the flash 21 is charged (step S505).

If it is determined that the exposure (AE) is appropriate (step S502), the measurement data and / or the setting parameters are stored in the internal memory or the memory 14 of the system control unit 22. Then, using the calculation result in the image processing unit 9 and the measurement data obtained by the AE control, the color processing is performed using the image processing unit 9 until it is determined that the white balance (AWB) is appropriate (step S506). AWB control is performed by adjusting processing parameters (step S50).
7).

If it is determined that the white balance (AWB) is appropriate (step S 506), the measurement data and / or setting parameters are stored in the internal memory of the system control unit 22 or the memory 14.
