摘要： PROBLEM TO BE SOLVED: To maintain angular velocity detecting accuracy of a laser gyro, even if ambient temperature and humidity fluctuates and a driving condition changes. SOLUTION: Semiconductor lasers 61a and 61b of this vibration detection device are serially connected and driven by a constant current. When angular velocity is added to the lasers 61a and 61b, beat signals whose phases are adjusted are generated and outputted via an arithmetic amplifier 66e. Then, bias frequencies included in the beat signals are different every semiconductor laser based on several factors, for example, manufacturing variance, temperature, humidity and changes due to time passage, after a power source is turned on. However, since the bias frequencies are averaged, the fluctuation factors of the detecting time of the angular velocity are also averaged. Thus, detecting accuracy is maintained stable.

摘要： PROBLEM TO BE SOLVED: To maintain the detection accuracy of angular velocity even when the internal impedance of a semiconductor laser is changed due to temperature or the like. SOLUTION: When the internal resistance of a semiconductor laser 61 is changed due to a cause other than the generation of a beat frequency, an error is generated in the detection of angular velocity. Then, before the angular velocity is detected, the internal resistance of the semiconductor laser 61 is checked. When the internal resistance is not changed at this time, the angular velocity is detected as it is. When the internal resistance is changed, its change is corrected. Even in a state that the angular velocity is input whenever the angular velocity is detected, in which state the output signal of an operational amplifier 66e is with reference to an initial value is detected, For this, an excitation signal is used. An excitation signal 11b from a camera microcomputer 11 is an alternating signal at a set high frequency, Thereby, an alternating voltage is generated from the operational amplifier 66e, The amplitude of the alternating voltage is changed when the internal resistance of the semiconductor laser 61 is changed, Thereby, a change in the internal resistance of the semiconductor laser 61 can be detected.

摘要： PROBLEM TO BE SOLVED: To accurately detect the defective actuation of an optical axis decentering means or a driving means for driving the optical axis decentering means by detecting electromotive force induced in the driving means in the midst of the optical axis decentering operation and detecting the propriety of the normal operation of the optical axis decentering means. SOLUTION: By detecting the electromotive force induced in the driving means in the midst of the optical axis decentering operation of the optical axis decentering means, whether the optical axis decentering means is normally operated is detected. Namely, when a main switch 13 is turned on, a camera microcomputer 11 energizes coils 68pa and 68pb so as to start shake correction, A 1st signal is superimposed on the coil 68pa together with a shake correction target value. Next, the electromotive force generated on the coil 68pb side is detected. Then, the state of an output signal from a window comparator 15p is decided. When the signal from the comparator 15p is inputted, superimposing the 1st signal is stopped and only the shake correction is performed. When the signal from the comparator 15p is not inputted, energizing the coils 68pa and 68pb is stopped to stop the shake correction, and a display device 16 is driven to perform abnormality display.

摘要： PROBLEM TO BE SOLVED: To obtain an optical equipment where accurate vibration-proof stable display is executed so as to prevent photographing from being executed in a shaken state in advance and which achieves a vibration-proof effect by controlling the operation condition of the optical equipment based on an arithmetic time constant. SOLUTION: A camera microcomputer 11 allows a display device 112 to display the information of plural devices 16 to 19 and means 110 and 111, and allows a flashing device 113 to emit light so as to compensate light quantity at the time of photographing if necessary. Namely, when the time constant of an arithmetic means consisting of a vibration detection means 111 and an integrator 114 and the like is large within a variable range, the vibration-proof stable display is executed or shake correction is started. When the time constant of the arithmetic means is small within the variable range, photographing is inhibited or a shutter release time lag is prolonged. Such control is executed not only by depending on the time constant of the arithmetic means but also by tinging it with output from the means 111 and the arithmetic means and information on the shutter speed and the focal distance of the optical equipment having a photographing function.
