Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention incorporates a vibration detecting sensor for detecting the vibration of a camera body, and corrects the vibration of a photographed image to be stored based on the detection result of the vibration detecting sensor. The present invention relates to a camera having a device.

[0002]

2. Description of the Related Art In describing conventional technology, a camera will be described as an example. Recent cameras are remarkably lightweight,
Even if the photographer shoots for a long time, heaviness is becoming less noticeable. However, as cameras have become lighter in weight, many blurred photographs have been seen in the photographs as a locus in which a subject image vibrates due to vibration caused by camera shake of a photographer. Further, there are cases where a slow shutter speed must be used due to various factors such as the brightness of the subject, the sensitivity of the film used, and the brightness of the lens used. In such cases, the photographer should be trained to prevent camera shake, attach the camera to a tripod for shooting, and increase the sensitivity of the film used.
There were restrictions and difficulties such as using an expensive lens with a large aperture.

Under these circumstances, recently, for example, while the camera is firmly fixed to a tripod, the camera shakes unintentionally due to the wind, or the camera shake that occurs when the camera is held by hand. Attempts have been made to reduce the influence of the vibration of the camera on the photograph in the camera or the taking lens. Conventionally, as this type of vibration correction device, there is known a device in which an angular velocity sensor is incorporated in a camera body or a photographing lens as a vibration detection sensor for detecting the above-mentioned vibration. Here, an example in which the vibration detection sensor is built in the camera body will be described. The angular velocity sensor detects the vibration of the camera body and outputs the detection result as an electric signal. Based on this output signal, an arithmetic circuit built in the camera calculates a deviation amount and a deviation direction in which direction and how much the object image on the photographing screen of the photographing film shifts due to vibration. Based on the result of this calculation, an actuator built in the lens and capable of driving a part of the photographing optical system in the direction perpendicular to the optical axis of the photographing optical system cancels the deviation amount and deviation direction of the subject image. To drive a part of the photographing optical system. This drive can reduce the vibration of the subject image on the shooting screen during exposure.

Further, this angular velocity sensor outputs a relative value such as how much a certain detection value and the next detection value change. When calculating the shift amount and the shift direction of the subject image using the relative detection value, the calculation circuit converts the relative detection value into an absolute amount from a reference value (hereinafter referred to as angular velocity = 0). I do. The detection output immediately after the start of detection by the angular velocity sensor has an unreliable output value because the angular velocity sensor itself is not in a stable state.
Therefore, it is necessary to start the calculation of angular velocity = 0 after the time when the detection output of the angular velocity sensor itself becomes stable.

Angular velocity = 0 is the average value of the detected values within a preset time from the start of the detection of the angular velocity to the end of the detection. This set time is the time obtained by adding the time required for the detection output of the angular velocity sensor itself to be in a stable state and the time required for the calculation of angular velocity = 0. The time required to perform the calculation of angular velocity = 0 is the time determined when the above-described calculation circuit calculates the shift amount and the shift direction of the subject image.

The longer the set time, the greater the detected value of the angular velocity, and the higher the accuracy of the angular velocity = 0 calculated as the average value of these values. However, if the set time is set too long, there will be a problem in that it takes a long time before shooting becomes possible. If the set time is set to a short time immediately after the detection of the angular velocity sensor, angular velocity = 0
Will be less accurate. Since the detection output of the angular velocity sensor itself is not in a stable state immediately after the detection of the angular velocity sensor is started, the detection value becomes unreliable.

As described above, when the photographer takes a picture by correcting the vibration with the camera having the built-in vibration correction device,
Compared with the case where vibration is not corrected, a series of operation time (hereinafter referred to as release time lag) until exposure is started on the shooting screen with full-press operation of the release button
In the case of using the vibration correction device for photographing, the time required for the vibration correction to operate is longer.

[0008]

When using a camera incorporating the above-mentioned conventional vibration correction device, for example, the photographer wants to take a photograph aiming at the moment when a moving subject crosses the front of the camera. And intended. Here, when shooting with and without operating the vibration compensator, the release time lags are not the same time, so it is difficult to understand when the release operation should be performed, and it is a feeling that a release operation is performed. Will be different. For this reason, not only is it difficult to obtain a photograph as intended, but there is also a problem that it is necessary to take a number of times to get a sense of it until an intended photograph is obtained.

This is a great obstacle to the photographer's familiarity and the intention of photographing when photographing with the same camera having the vibration correcting device function. The present invention has been made to solve the above-described problems, and a camera having a vibration correction device that controls the release time lag to be the same time regardless of the operation of the vibration correction device is provided. The purpose is to provide.

The processing shown in FIGS. 2 and 3 below is a photographing processing which is started by the half pressing operation S1 of the release button in the control circuit 10 of the first embodiment of the present invention. When S1 is turned on, program processing of the control circuit 10 including the CPU is started. As described above, the blur detection sensor 25 uses an angular velocity sensor. Below, the half-pressing operation of the release button will be abbreviated as S1, the full-pressing operation as S2, and the steps as S.

Go to 0. If NO, the process returns to S209. Where N
In case of O, it waits until t5 time is reached, so S1
Even if S2 is performed immediately afterward, the angular velocity = 0, which is the reference of the shake correction drive, is surely detected, so that the shake correction drive can be surely performed. Further, in the case of YES, when the time of S1 is sufficiently long and the time until the next S2 signal is performed has passed t5 hours or more, the shake correction start signal is output immediately after S2. . Next, S2
In 10, the shake correction start command for starting the shake correction is output, and the process proceeds to S211. In step S211, it is determined whether t6 hours, which is the time required to start the shake correction, has elapsed from the shake correction start command. If YES, the process proceeds to S212. If NO, the process returns to S211. Next, in S212, the driving of the blur correction lens 3 is started via the blur correction lens drive unit 29. Then, the exposure calculation circuit 15 starts the exposure by driving the diaphragm 6 and the shutter 7 so as to have a predetermined value based on the exposure calculation result, and proceeds to S213. S21
In 3, the elapsed time from the start of exposure (hereinafter referred to as t)
, It is determined whether the total exposure time (hereinafter referred to as t1) has been reached. If YES, the process proceeds to S214. If NO,
Return to S213. In S214, the exposure calculation circuit 1 is immediately executed.
In No. 5, the diaphragm 6 and the shutter 7 are driven again to end the exposure, and the process proceeds to S215. In step S215, the shake correction calculation circuit 27 outputs a stop signal for stopping the shake correction to the shake correction lens drive circuit 28, and the shake correction lens drive unit 2
The vibration reduction lens group 3 is stopped via 9, and the process proceeds to S216. In S216, the blur detection sensor (angular velocity sensor)
The power supply to 25 is turned off, the blur detection is stopped, and the process proceeds to S217. In S217, the shake correction lens group 3 is reset, and a series of operations related to shooting ends (END).

If the VR is not turned on (NO in S208), the following operation of FIG. 3 is performed. In the following, in S301, t2 time as the elapsed time from S1 of the release button is the above-mentioned t5 time and VR.
When is turned on (in the case of YES), it is determined whether the total time of t6 hours or more has been reached. If YES, S
Proceed to 302. If NO, the process returns to S301. Here, the release time lag from S2 of the release button to the start of exposure is when VR is ON (YES
In the case of), it is the same time as the release time lag. As a result, since the time is the same regardless of whether the VR is turned on or off, it is possible to start shooting with the same release time lag.

Next, in S302, the exposure calculation circuit 1
5 starts the exposure by driving the diaphragm 6 and the shutter 7,
Proceed to S303. In S303, it is determined whether the elapsed time t from the start of the exposure has reached the total exposure time t1.
If YES, the process proceeds to S304. If NO, S3
Return to 03. In S304, the exposure calculation circuit 1 is immediately executed.
In step 5, the diaphragm 6 and the shutter 7 are re-driven to end the exposure, and the process proceeds to S305. In S305, the blur detection is stopped and the photographing operation is ended (END).

The time t5 is the time until the angular velocity = 0 detected and calculated by the blur detection sensor (angular velocity sensor) 25 and the blur correction arithmetic circuit 27 is detected. Depends on precision, t
It can be changed by the 5-hour setting unit. Therefore, angular velocity =
It goes without saying that the time t5 can be taken sufficiently when the accuracy of 0 is desired to be increased, and vice versa.

Next, the processing shown in FIGS. 4 and 5 is a photographing processing which is started by the half pressing operation S1 of the release button in the control circuit 10 of the second embodiment of the present invention. This S1 is ON
Thus, the program processing of the control circuit 10 including the CPU is started. As described above, the blur detection sensor 25 uses an angular velocity sensor. The control circuit 10 starts the photographing process in START. Then, in S401,
It is determined whether the photographer has pressed the release button S1. If YES, the process proceeds to S402. If NO, return to START. Next, in S402, the shake correction selection device (VR)
Judge whether is turned on. If YES, S4
Go to 03. If NO, go to. Next, S403
Then, the angular velocity sensor 25 is turned on to start the shake detection, and the process proceeds to S404. In S404, the shake correction calculation circuit 27 calculates the reference angular velocity = 0 based on the output of the angular velocity sensor 25, and proceeds to S405. S405
In step 1, the exposure calculation circuit 15 measures the brightness of the subject with the photometric sensor 12 and reads the ISO sensitivity of the photographic film 8 from the DX code written on the cartridge of the photographic film 8 with the DX contact 11. Then, the exposure calculation circuit 15 performs photometry calculation, and proceeds to S406. S4
At 06, it is again determined whether the release button is S1. YE
In the case of S, the process proceeds to S407. In case of NO, STAR
Return to T. Next, in S407, it is determined whether or not the release button is S2. If YES, the process proceeds to S408. If NO, the process returns to S407. Next, in S408, the preset value of t5 time as the time until the calculation of the angular velocity = 0 set in advance is read from the t5 time setting unit 21, and the process proceeds to S409.

Since the operation from S409 to S417 is the same as the operation from S209 to S217 of the above-described first embodiment, the description thereof will be omitted. If VR is not turned on in S402 described above (NO
Case), the following operation of FIG. 5 will be described. In the following, in S501, the exposure calculation circuit 15
The photometric sensor 12 measures the brightness of the subject, and the DX contact 11 reads the ISO sensitivity of the photographic film 8 from the DX code written on the cartridge of the photographic film 8. Then, the exposure calculation circuit 15 performs photometry calculation,
It proceeds to S502. In S502, press the release button again to S1.
Judge whether you have done. In the case of YES, it progresses to S503. N
In the case of O, the process returns to step 401 (S401) in FIG. Next, in S503, it is determined whether the release button is S2. If YES, the process proceeds to S504. If NO, the process returns to S503. Next, in S504, the preset value of t5 time as the time until the preset calculation of the angular velocity = 0 is read from the t5 time setting unit 21 and S5
Proceed to 505. In S505, t2 time as the elapsed time from S1 of the release button is the above-mentioned t5 time and V
If R is ON (YES), it is determined whether the total time of t6 hours or more is reached. If yes,
Proceed to S506. If NO, the process returns to S505. Here, the release time lag from S2 of the release button to the start of exposure is when VR is ON (YES
In the case of), it is the same time as the release time lag. As a result, since the time is the same regardless of whether the VR is turned on or off, it is possible to start shooting with the same release time lag.

Next, in S506, the exposure calculation circuit 1
5 starts the exposure by driving the diaphragm 6 and the shutter 7,
Proceed to S507. In step S507, it is determined whether the elapsed time t from the start of exposure has reached the total exposure time t1.
If YES, the process proceeds to S508. If NO, S5
Return to 07. In step S508, the exposure calculation circuit 1 is immediately executed.
In step 5, the diaphragm 6 and the shutter 7 are driven again to end the exposure, and the photographing operation is ended (END).

Here, the effect of the second embodiment is that the shake correction selection device (V
When R) is not turned on (NO), the operation of the shake detection sensor (angular velocity sensor) 25 is prohibited, so that the power consumption of the power supply battery built in the camera body 1 can be suppressed. As in the first embodiment, the time t5 is the time until the angular velocity = 0 detected and calculated by the blur detection sensor (angular velocity sensor) 25 and the blur correction computing circuit 27. The time depends on the accuracy of angular velocity = 0 and can be changed by the t5 time setting unit. Therefore, it goes without saying that when it is desired to improve the accuracy of angular velocity = 0, the time t5 can be taken sufficiently and vice versa.
