Since it is described in, for example, JP-A-148730, description thereof is omitted here.

The X-axis wedge prism 14 can deflect a light beam passing through the prism in the X-axis direction by a drive signal from an X-axis wedge prism drive circuit 27. Similarly, the Y-axis wedge prism 15 is controlled by a Y-axis wedge prism drive circuit 28.

This camera has an X-axis shake detection gyro 2 for detecting the camera shake angle in the X-axis direction.
9 and a Y-axis shake detection gyro 30 for detecting a shake angle of the camera in the Y-axis direction.

As a gyro usable for a camera, a vibrating gyro is typical and has already been commercialized. This type of gyro outputs an angular velocity signal. Therefore, it is necessary to integrate the angular velocity signal in order to obtain the blur angle. For this purpose, an X-axis integration circuit 31 and a Y-axis integration circuit 32 exist.

The outputs of the integrating circuits 31 and 32 for the X and Y axes are input to an A / D converter 34 through an analog multiplexer (hereinafter simply referred to as a multiplexer) 33. By switching the multiplexer 33 as needed, the system controller 20 can input a two-axis blur angle signal as a digital signal with one A / D converter. The reset circuit 3

The image display circuit 39 is for displaying the image data taken from the image sensor 16 on the liquid crystal monitor 40. The camera user can observe the subject through the liquid crystal monitor 40.

Further, a liquid crystal 45 provided in a finder optical system 44 is connected to the system controller 20 via a finder liquid crystal drive circuit 43, and a distance measuring circuit 46, a photometric circuit 47, and a temperature measuring circuit. 48,
Power switch (SW) 51 and release switch (S
W) 52 is connected.

A liquid crystal panel as shown in FIG. 2 is arranged inside the finder as a display means for indicating the position of the subject. By using the viewfinder, the camera user can check the subject similarly to the liquid crystal monitor. The liquid crystal panel 45 includes a plurality of segments (Seg)
_00, Seg _01, ..., and a Seg _nm). Each segment is driven by a control signal of a liquid crystal drive circuit 43 in the finder. System controller 20
, It is possible to change the transmittance of an arbitrary segment based on the command from.

At the center of the liquid crystal panel 45, a focus area 61 is drawn. The user can focus on the subject by holding the camera and operating the release switch 52 so that the subject enters the focus area 61. Further, the focus area 61 and the photometry area of the photometry circuit 47 are located at substantially the same position.

As shown in FIG. 3, on the liquid crystal monitor 62, the image data and the focus area 63 are combined and displayed.

The distance measuring circuit 46 is a circuit for measuring the distance to the subject, and based on the measured distance,
The photographing lens 11 is driven. Also,
The photometry circuit 47 is a circuit for measuring the brightness of the subject. Based on the information on the measured luminance, the set value of the aperture 12 and the shutter time (integration time) of the image sensor 16 are determined.

The temperature measuring circuit 48 is for measuring the temperature when the camera is operating. It is necessary to correct the drive voltage of the wedge prism in the blur correction optical system 13 according to the temperature.

The nonvolatile storage memory (EEPROM)
A driving parameter 50 required for driving the blur correction wedge prism is stored in 50.

The power switch 51 is an operation switch for determining the operation and non-operation of the camera. Operation is possible while the power switch 51 is on.

Further, the release switch 52 includes a first release switch 53 and a second release switch 5.
4 switches. When the release switch 52 is half-pressed, the first release switch 5
3, the first release switch 53 and the second release switch 54, which are fully pressed, are turned on.

Next, referring to the flowcharts of FIGS. 4 and 5, the system controller 2 according to the present embodiment will be described.
The operation of 0 will be described.

When the power switch 51 is turned on, power is supplied to the system, and the operation is started by the system controller 20. Then, in step S1, an initial setting operation is performed. The initialization operation includes initialization of an I / O port, initialization of a memory, and initialization of a circuit connected to the system controller 20. Then
In step S2, the current camera temperature data is input from the temperature measurement circuit 48.

In step S3, data indicating the voltage applied to the wedge prism from the EEPROM 50 is read. The EEPROM 50 stores, for example, a data table as shown in Table 1 below. Table 1 shows that X
5 is a data table showing applied voltages necessary for controlling the axial wedge prism 14.

[0041]

[Table 1]

In consideration of the temperature characteristics of the material constituting the prism, the data table needs to be changed according to the temperature. In the example shown in Table 1, the temperature range in which the camera is used is temporarily divided into three regions.
For example, if the temperature measured in step S2 is 20 ° C., the data table indicated by * 1 in Table 1 is an EEP
It is read from the ROM 50. In the EEPROM 50, Y
A data table for the axial wedge prism is also stored,
Since it is the same as the data table for the X-axis wedge prism,
Here, the description is omitted.

In step S3, 20 ° C.
Is read out. Then, the read data is stored in a memory in the system controller 20. In step S4, the centering voltage indicated by * 2 in Table 1 is changed to the X-axis wedge prism 1
4 and the Y-axis wedge prism 15.

In a system for performing image stabilization by shifting or tilting a part of a lens group of the photographing optical system, prior to the image stabilization operation, this lens group is moved to a neutral position (the center of the shift or tilt range). ). This operation is called a centering operation.

In the case of performing the image stabilizing operation using the wedge prism, an operation corresponding to the centering operation is required. This is the operation of step S4. Due to the application of the centering voltage, the light passing through the prism passes without swinging.

By changing the voltage applied to the prism on the basis of the centering voltage, it is possible to correct the subject image on the image pickup device which is displaced due to blur.

In step S5, the state of the position measurement flag is determined. This flag is set when the first release switch 53 is turned on. In conjunction with the operation of setting the flag, the photometric value is locked (AE
Locked). Therefore, if the flag is "1", the process proceeds to step S8, and the operations of steps S6 and S7 are not executed. On the other hand, if the flag is “0”, the flow shifts to step S 6, where luminance information is input from the photometry circuit 47. Then, the shutter time (the integration time of the image sensor 16) and the set value of the aperture 12 are determined.

The exposure parameters determined in step S6 are transferred to the image data controller 18 in step S7. Then, in step S8, an image capturing operation is instructed to the image data controller 18. In the image data controller 18, the imaging device 1
6 is controlled to input image data. Then, the image data and the exposure parameters are displayed on the liquid crystal monitor 40.

Next, in step S9, the state of the first release switch 53 is detected. here,
If the first release switch 53 is off, the process proceeds to step S10. If the first release switch 53 is on, the process proceeds to step S15.

In step S10, the position measurement flag is cleared (← “0”). Next, in step S11, the image data controller 18 is instructed to display the marker mark (the position where the AE lock or the AF lock is performed) on the liquid crystal monitor
0) is instructed to be erased.

In step S12, the finder optical system 4
The position segment (segment indicating the position of the AE lock or the AF lock) of the liquid crystal panel 45 in 4 is erased. With this operation, the liquid crystal panel 45 of the finder optical system 44 is in a state of transmitting the entire surface.

Then, in step S13, the state of the power switch 51 is detected. Here, if the power switch 51 is on, the process proceeds to step S5, and if it is off, the process proceeds to step S14.

In step S14, an operation for stopping the system is performed, and the system controller 20 is stopped.

If it is determined in step S9 that the first release switch 53 is ON, the process proceeds to step S1.
The process proceeds to 5, where the status of the position measurement flag is determined.
Here, if the position measurement flag is “0”, it indicates that immediately after the first release switch 53 is turned on. On the other hand, if the flag is “1”, the distance measurement operation and the photometry operation are completed, and the position measurement operation (AF lock or A
(Operation of measuring the position on the shooting screen where E lock is performed).

If the flag is "0" in step S15, the process proceeds to step S16, and the position measurement flag is set (← "1"). Next, in step S17,
The reset circuit 35 is controlled, and the X-axis integration circuit 31 and the Y-axis integration circuit 32 are initialized. With this operation, the position measurement operation has been started.

In step S 18, distance data of a subject existing in the focus area is input from the distance measuring circuit 46. This distance measurement operation is not performed again while the first release switch 53 is on due to the action of the position measurement flag. That is, the AF lock is performed.

The operations in steps S19 and S20 are the same as those in steps S6 and S7 described above, and a description thereof will be omitted. Like the distance measuring operation, the light measuring operation is not executed again while the first release switch 53 is on. That is, the AF lock has been achieved.

Next, in step S21, the initial position data is transferred to the image data controller 18. Then, in step S22, the image data controller 18 is instructed to display the sign mark. By these two operation steps, a marker mark is displayed together with the image data already displayed at the center of the liquid crystal monitor 40.

In step S23, an initial position is displayed on the liquid crystal panel 45 in the finder. By this operation, the segment located at the center of the liquid crystal panel 45 enters a semi-transmissive state.

Then, in step S24, the state of the second release switch 54 is determined. here,
If the second release switch 54 is off, the process proceeds to step S5, and if it is on, the process proceeds to step S31.

In step S15, if the position measurement flag is "1", it indicates that the AE lock and the AF lock have been completed. In addition, since the first release switch 53 is in the ON state, the camera user shakes the camera and changes the composition while watching the subject on the viewfinder or the liquid crystal monitor 40 after the lock operation ends. ing.

At this time, if the amount of camera shake is determined by a gyro, it is possible to determine where in the shooting area the subject is located.

Therefore, in step S15, when the position measuring flag is "1" and the process proceeds to step S25, the shake angle in the X-axis direction is measured. The output of the X-axis integration circuit 31 is subjected to A / D conversion through the multiplexer 33, so that the shake angle (θ _x ) in the X-axis direction can be detected.

Next, in step S26, the blur angle in the Y-axis direction is measured. Through multiplexer 33,
The output of the Y-axis integration circuit 32 is subjected to A / D conversion, whereby Y
The shake angle (θ _y ) in the axial direction can be detected.

Then, in step S27, the two angles (θ _x , θ _y ) obtained are converted into position data on the photographing area.

As shown in FIG. 6, the X-axis and the Y-axis are set with the center of the photographing area 65 as the origin (0, 0). The center is used as the origin because the focus area exists in the center.

The position of the subject locked by the user is obtained by the following equation. _{X = f · tan θ x Y} = f · tan θ y ... (1) f is the focal length of the taking lens 11.

Next, in step S28, the position data obtained by the above equation (1) is
8 is transferred. In step S29, display of a sign mark is instructed to the image data controller 18 based on the position data. Then, in step S30, only the segment of the liquid crystal panel 45 corresponding to the position data obtained by the above equation (a) is set to the semi-transmissive state.

While the first release switch 53 is on, the operations of steps S25 to S30 are periodically performed. Therefore, the user who observes the liquid crystal monitor 40 can observe the sign mark indicating the subject position moving on the monitor in conjunction with the framing change operation. The user observing the viewfinder
In conjunction with the framing change operation, it is possible to visually recognize how the position segment (semi-transparent portion) indicating the subject position moves.

FIG. 7 shows the movement of the marker on the liquid crystal monitor 40 and the position segment of the finder liquid crystal.
This will be described with reference to FIGS.

As shown in FIG. 7, it is assumed that the user turns the camera 66 to the position indicated by the mark 67 and half-presses the release switch 52. At this time, a bird that is the subject 68 exists in the focus area. By this half-pressing operation, a focus lock operation and an AE lock operation are performed on the subject. At this time, the integration circuit is initialized, and measurement of the position of the subject is started.

It is assumed that the user has shaken the camera 66 to the position indicated by the mark 67 'while keeping the release switch 52 half-pressed. At this time, if the user is operating the camera 66 while looking at the viewfinder,
Scenes as shown in FIGS. 8A, 8B, 8C, 8D and 8E are observed.

FIG. 8A shows a state immediately after the release switch 52 is half-pressed. When the focus lock operation and the AE lock operation are completed, the focus area 6
The position segment 69 located at 1 is translucent. When the semi-transmissive position segment 69 appears, a display indicating the end of the focus lock operation and the AE lock operation is displayed.

After confirming this, the user shakes the camera 66 in the direction indicated by the arrow A in FIG. As a result, the composition is changed from the sign mark 67 to the position indicated by the sign mark 67 '. In conjunction with this operation, the semi-transparent position segment 69 becomes
It moves as shown in (a) → (b) → (c) → (d) → (e). Since the moving position segment 69 overlaps with the subject, it is possible to know what the focus locked and the AE locked subject are.

When the user operates the camera 66 while observing the liquid crystal monitor 40, FIGS. 9A, 9B, 9C,
Scenes as shown in (d) and (e) are observed.

FIG. 9A shows a state immediately after the release switch 52 is half-pressed. The image data, the mark mark 70, the focus area 63, and the exposure parameter 71 are synthesized by the image data controller 18 and displayed on the monitor. The display of the sign mark 70 is started when the focus lock and the AE lock are completed. The exposure parameter 71 also responds to the AE lock operation,
The display no longer changes.

When the user shakes the camera 66, the marker 70 moves as shown in FIGS. 9 (a) → (b) → (c) → (d) → (e). At this time, the subject image and the mark 70 overlap.

Returning to the flowchart of FIG. 4, in step S24, the state of the second release switch 54 is detected. Here, the second release switch 5
If 4 is off, the process proceeds to step S5, and if it is on, the process proceeds to step S31.

In step S31, the above-described step S18
The amount of movement of the photographing lens 11 is calculated on the basis of the subject distance information obtained in. In the following step S32, the photographing lens 11 is driven by the lens driving circuit 21 and the lens driving mechanism 22 based on the calculated movement amount. Further, in step S33, the aperture value determined in step S19 is added to the aperture driving circuit 23 and the aperture driving mechanism 24.
The aperture 12 is set.

In step S34, the X-axis integration circuit 31 and the Y-axis integration circuit 32 are initialized. By integrating the output of the gyro, the shake angle of the camera can be detected. If a light beam passing through the wedge prism is shaken in a direction to offset the shake angle, the subject image formed by the photographing lens 11 is fixed in space. This is the image stabilization operation by the wedge prism.

At the start of the image stabilizing operation, the X-axis integration circuit 31 and the Y-axis integration circuit 32 are initialized, and the outputs are returned to the reference values. This operation is performed by the reset circuit 3
5 through.

Next, in step S35, the image data controller 18 is instructed to start the integration operation of the image sensor 16. In step S36, the counting operation of the timer counter is started to measure the shutter time.

Then, in step S37, it is determined whether or not the value of the timer counter has reached the shutter time determined in step S19. If the shutter time has not been reached, the process proceeds to step S38.

In step S38, the output of the X-axis integration circuit 31 is input to the A / D converter 34 through the multiplexer 33. Further, the X-axis camera shake angle is measured through the A / D converter 34.

In the following step S 39, the voltage to be applied to the X-axis wedge prism 14 is obtained from the measured shake angle of the camera 66 and the table data already read from the EEPROM 50. For example, if the camera shake angle is-
In the case of 0.4 (degree), it is only necessary to swing a +0.4 (degree) ray by the prism. From * 1 in Table 1 above, the voltage to be applied is 3.0 (V).

Step S is performed so that this voltage is applied.
At 40, the D / A converter of the X-axis wedge prism drive circuit 27 is set. The deflection angle of the camera 66 is -0.45
In the case of an angle that does not exist in Table 1 as in (degrees), an intermediate value may be obtained based on the applied voltage data at +0.4 degrees and +0.6 degrees.

In the following steps S41, S42 and S43, the same operations as those in steps S38, S39 and S40 are performed on the Y axis. Then, after the end of step S43, the process proceeds to step S37 to detect the value of the timer counter.

As described above, since the operations of steps S 38 to S 43 are repeated at a high speed during the integration operation of the image sensor 16, the subject image on the image sensor 16 is fixed irrespective of the camera 66 shake.

In step S37, when the count value of the timer counter reaches the shutter time,
Move to step S44. In this step S44,
The image data controller 18 is instructed to capture image data. The integration operation of the image sensor 16 is stopped by the image data controller 18 and the image sensor 1
The image data is read out from 6. The read image data is stored on the DRAM 38.

Next, in step S45, an instruction to create an image file is issued to the image data controller 18. Here, the image data controller 18 converts the captured image data into a predetermined format.

In step S46, the image data controller 18 is instructed to store an image file. Then, the image file is stored in the image data recording medium 41 by the image data controller 18.

Further, in step S47, the diaphragm 12 is driven to the open position. Thereafter, the process proceeds to step S2.

The above embodiment is based on the assumption that an electronic still camera is used. However, the present invention is not limited to this, and can be applied to a camera system using a silver halide film.

In a silver halide film camera, since there is usually no image pickup device, it is difficult to display the position of a subject using the liquid crystal monitor described in the present embodiment. However, arranging a liquid crystal in the viewfinder and indicating the position using the liquid crystal can be sufficiently used even with a silver halide film camera.
