Abstract

PROBLEM TO BE SOLVED: To quickly correct a camera-shake by resetting a power supply timer and continuing the supply of power to camera-shake detecting means, when camera-shake detecting signals from the camera-shake detecting means are within fixed ranges where normal camera-shakes, or the like, are shown or it is discriminated that the output of an attitude sensor is not changed. SOLUTION: This camera-shake correcting device is provided with the camera-shake detecting means 15a and 15b, a correcting means 18, a camera- shake control means 16, an operating switch 11, a power supply timer means 13 and a timer control means 17. The timer control means 17 resets the power supply timer 13, to continue the supply of the power to the camera-shake detecting means 15a and 15b, because there is a strong possibility that the correcting means 18 is used again, when the camera-shake detecting signals from the camera-shake detecting means 15a and 15b are within the fixed ranges where the normal camera-shakes, or the like, are shown or it is discriminated that the output of the attitude sensor is not changed. Further, when a periodical frequency component is included, the power supply timer 17 is immediately stopped even before it reaches for a specified time, to stop the supply of the power to the camera-shake detecting means 15a and 15b.

A vibration type angular velocity sensor (hereinafter, referred to as a vibration gyro) is widely used. FIG. 7 shows a circuit configuration until the angular velocity signal output from the vibration gyro is converted into a vibration angular displacement signal. The angular velocity signal output from the vibration gyro 51 is converted by a high-pass filter (HPF) 52.
After the unstable fluctuation in the ultra-low frequency range of 0.01 Hz or less is removed and amplified by the amplifier 53, the integrator 54 converts the fluctuation into a vibration signal having an angular displacement in a camera shake detection frequency band of 0.1 Hz to 50 Hz.

給を停止させる。If the switch IS-SW is not turned on while the power supply timer 13 is counting the predetermined time, the process proceeds from step # 209 to step # 210, where the hand shake control unit 16 detects a repetitive periodic shake. It is determined whether or not it has been performed. As a result, when the repetitive periodic vibration is detected, the process proceeds to step # 213, and it can be inferred that the user is walking or in the vehicle by using the specific frequency range. The timer control unit 17 causes the power control circuit 12 to stop supplying power to all camera shake correction devices including the camera shake detection system power supply in order to prevent useless power consumption (standby current).

From step 211, the process proceeds to step # 212. Here, if the level of the camera shake detection signal from the camera shake detection circuits 15a and 15b is within a predetermined range, that is, if a signal indicating a normal camera shake occurrence state is output, the process proceeds to step # 214. The timer control means 17 operates to predict the switching of the switch IS-SW, resets and extends the count value of the power supply timer 13, returns to step # 207, and repeats the same operation as described above. When the count value of the power timer 13 reaches a predetermined count value (Y in step # 211).

When the shake detection signal from the vibration detection means is within a predetermined range indicating normal camera shake or when it is determined that the output of the posture sensor does not change, there is a high possibility that the correction means will be used again. The power supply timer is updated so that power is continuously supplied to the vibration detecting means, or the shake detection signal from the vibration detecting means can be regarded as a state in which the device body is in an unused state, for example, in a car or walking. When a periodic frequency component is included, the power supply timer is stopped immediately before reaching a predetermined time, and the power supply to the vibration detecting means is cut off. Thus, it is possible to prevent the shake from being immediately corrected immediately after the start of the driving of the correcting unit is instructed, and prevent the power from being wasted unnecessarily.
