Abstract

PURPOSE:To perform camera shake correction and opening/closing a shutter only when the voltage value of a batery is equal to or above a specified value by measuring the voltage value of the battery before performing the camera shake correction. CONSTITUTION:This invention is applied to a camera shake correction camera provided with a CPU 2, motor driving circuits 8 and 9, an LCD 13, angular velocity detection circuits 20 and 21, and a correction lens 102. When a release button is half depressed, the CPU 2 drives a motor to move the correction lens 102 toward a reset position and simultaneously performs battery-check in a state where the motor is driven in a direction where the shutter is closed. When the result of the battery-check is NG, the LCD 13 is totally turned off and photographing is inhibited. On the other hand, by fully depressing the release button when the result of the battery-check is OK, the shutter is opened/closed and photographing is performed while performing the camera shake correction. Since the camera shake correction is not performed in a state where the voltage is low, accuracy in the camera shake correction is kept constant.

FIG. 2 is a flowchart showing the main processing of the CPU 2. When the main switch 14 is turned on, C
PU2 starts the process of this flowchart. In step S1 of FIG. 2, it is determined whether the half-push switch 15 is on. If the determination is denied, the process stays in step S1,
If the determination is positive, the process proceeds to step S2. Step S2
Then, the battery check process of FIG. 3 described later is performed. In step S3, the flag B indicating the battery check result is displayed.
It is determined whether C is "0". The flag BC is "0" when the power supply voltage supplied from the battery (not shown) is equal to or lower than the predetermined voltage, and is "1" when the power supply voltage is higher than the predetermined voltage. In the following, when the flag BC is "1", the battery check is called OK, and when it is "0", it is called NG.
If the determination in step S3 is affirmative, the process proceeds to step S4, the LCD 13 is all turned off, and the process ends. In this case, shooting is prohibited even if the release button is fully pressed, and once the release button is returned to its original position and half-pressed again, the processing of FIG. 2 is started. The main switch 14 may be turned off in step S4.

On the other hand, if the determination in step S3 is negative, the process proceeds to step S5 to send a signal to the angular velocity detection circuits 20 and 21 to instruct the start of angular velocity detection. As a result, the angular velocity detection circuits 20 and 21 operate the shake detection sensor (not shown) to detect the angular velocity caused by the shake. In step S6, a signal is sent to the photometric circuit 11 to start the photometric processing. Then, the exposure calculation is performed based on the photometric result, and the aperture amount and the shutter opening time required for photographing are obtained. In step S6, a signal is sent to the focus adjustment information detection circuit 12 to start focus detection processing. Then, the focus lens 101 is moved to the focus position.

In step S7, it is determined whether or not the release button has been fully pressed depending on whether or not the release switch 16 is on. If the determination is negative, the process proceeds to step S8, and whether or not the release button is half-pressed. Is determined by whether the half-push switch 15 is on. If the determination is negative, it is determined that the shooting has been stopped, and the processing ends, and if the determination is positive, the process returns to step S7.

On the other hand, if the determination in step S7 is affirmative, the flow advances to step S9 to start moving the correction lens 102. Specifically, the movement amount of the correction lens 102 is calculated based on the outputs of the angular velocity detection circuits 20 and 21, and the drive direction signal and the drive duty signal are sent to the motor drive circuits 8 and 9. As a result, the correction lens 102 is responsive to the angular velocity due to camera shake detected by the angular velocity detection circuits 20 and 21.
Move in two orthogonal directions. In step S10, the shutter 105 is opened to start the exposure process. Then, when the shutter open time calculated in step S6 has elapsed, the process proceeds to step S11, the shutter 105 is closed, and the exposure process ends. In step S12, the motor drive circuit 8,
A signal is sent to 9 to stop driving the motors 4 and 5. In step S13, the supply of the power supply voltage to the angular velocity detection circuits 20 and 21 is stopped, and in step S14, the film is wound up for one frame and the process is ended.

FIG. 3 is a flow chart showing details of the battery check process in step S2 of FIG. In step S51 of FIG. 2, a signal is sent to the motor drive circuits 7-9 to drive the motors 3-5. Here, the correction lens 10
The motors 4 and 5 are driven in the direction in which the motor 2 is moved to the reset position, and the motor 3 is driven in the direction in which the shutter 105 is closed. In this way, when checking the battery, the motor 3
The reason why ~ 5 is driven is that accurate voltage measurement cannot be performed even if the battery is checked without driving the load. In step S52, the motors 3 to 5 are driven until the predetermined time elapses. Waiting in step S52 is because the power consumption of the motors 3 to 5 fluctuates for a while after the driving of the motors 3 to 5 is started,
This is because accurate voltage measurement cannot be performed even if the battery check is performed in such a state.

In step S53, the power supply voltage supplied from the battery is detected, and the value obtained by A / D converting the voltage value (hereinafter referred to as voltage detection value) VE is read. Step S5
4 sends a signal to the motor drive circuits 7 to 9 to drive the motor 3
Stop the driving of ~ 5. In step S55, it is determined whether or not the voltage detection value VE is equal to or lower than the predetermined voltage VBC. If the determination is negative, it is determined that the battery check is OK, the process proceeds to step S56, the flag BC is set to "1", and the process returns. To do. On the other hand, if the determination is positive, the battery check is N
When it is determined to be G, the process proceeds to step S57, the flag BC is set to "0", and the process returns.

As described above, in the first embodiment, the battery check is performed with the release button half-pushed, and the photographing is prohibited when the power supply voltage supplied from the battery is equal to or lower than the predetermined voltage. The problem that camera shake correction control and shutter opening / closing control are not performed correctly due to low voltage is solved. Further, since the battery check is performed while driving the motor for moving the correction lens and the motor for opening / closing the shutter, the power supply voltage supplied from the battery can be accurately detected. Moreover, at that time, since both motors are driven in a direction that does not hinder shooting, battery checking can be performed without adversely affecting shooting.

Second Embodiment In the first embodiment, photographing is prohibited when the battery check is NG, whereas in the second embodiment described below, the battery check is NG. In this case, only the camera shake correction process is not performed, and shooting can be performed normally. Since the second embodiment has the same configuration as that of the first embodiment shown in FIG. 1, the description of the configuration will be omitted and the processing of the CPU will be described based on the flowchart of FIG. The CPU starts the process of FIG. 4 when the main switch is turned on.

The processing from steps S101 to S103 in FIG. 4 is common to the processing from steps S1 to S3 in FIG. If the determination in step S103 is affirmative, the process proceeds to step S104, and all the LCDs 13 provided in the camera blink. LCD 13
Blinking indicates that the power supply voltage supplied from the battery has dropped. When the process of step S104 ends, the angular velocity detection circuits 20 and 21 are not operated and the process proceeds to step S106 to perform the photometry / focus detection process.
Therefore, when the power supply voltage is low, the shake detection is not performed. The processes of steps S105 to S108 are common to steps S5 to S8 of FIG.

In step S109, it is determined whether or not the battery check is NG. If the determination is negative, the process proceeds to step S110, and the movement of the correction lens 102 is started.
When the process of step S110 ends and step S1
If the determination of 09 is affirmative, step S111 is performed.
Then, the shutter 105 is opened to start the exposure process.
Then, after a lapse of a predetermined time, the process proceeds to step S112 to end the exposure process. Next, in step S113, it is determined whether or not the battery check is NG. If the determination is negative, the process proceeds to step S114 to stop the movement of the correction lens 102, and then the process proceeds to step S115 to send a signal to the angular velocity detection circuits 20 and 21 to stop the operation of the shake detection sensor. When the determination in step S113 is affirmative and after the process of step S115 is completed, the process proceeds to step S116 to wind the film and end the process.

As described above, in the second embodiment, the battery check is performed while the release button is half-pushed, and when the battery check is NG, the image pickup is performed without the camera shake correction. It is possible to continue shooting even if the value decreases. Further, since the image capturing is performed without the camera shake correction, the power consumption can be saved. Further, when the voltage is low, the camera shake correction is forcibly stopped as in the first embodiment, so that the accuracy of the camera shake correction can be kept constant. Furthermore, when the battery check is NG, the image is taken while the LCD 13 blinks, so that the photographer can visually recognize whether or not the battery voltage has dropped.

In each of the above embodiments, the battery check is N
In the case of G, all the LCDs are turned off or blinking, but instead of turning off or blinking, the fact that the power supply voltage of the battery is lowered may be notified by a character display or a warning sound. In the above embodiment, the example in which the shake detection sensor detects the angular velocity caused by the shake is shown. However, the angular velocity detection circuit 2
Instead of 1 and 22, acceleration other than angular velocity, position change, etc. may be detected. As the focus detection method of the focus adjustment information detection circuit of the above embodiment, various methods such as a method based on a distance measuring method for measuring a subject distance and a method based on a focus detection method for examining the state of the focal plane of the photographing lens are available. Applicable.

In the embodiment constructed as described above,
The battery serves as a power supply voltage supply means, the shutter 105, the motor 3
The motor control circuit 7 serves as the exposure control means, the angular velocity detection circuits 20 and 21 serve as the camera shake detection means, and the correction lens 10
2, the motors 4 and 5 and the motor drive circuits 8 and 9 serve as camera shake correction means, the processing of FIG. 3 serves as voltage measurement means, step S3 of FIG. 2 serves as determination means, and step S4 of FIG. 2 serves as shooting prohibition means. Step S104 in FIG. 4 corresponds to the correction-prohibited photographing means, the motor 3 and the motor drive circuit 7 correspond to the shutter drive means, and the motors 4, 5 and the motor drive circuits 8 and 9 correspond to the correction lens drive means.
