ABSTRACT:
A fluctuation stabilizing apparatus is provided in which, in a process of integrating a motion vector to obtain an indication of the amount of image fluctuation, the integration characteristic is controlled in accordance with the magnitude of the integration result of the motion vector. A centering controller attenuates the output signal from the integrator in accordance with the magnitude of the output signal from the integrator. A memory interpolation controller shifts the position at which an image signal is read out of an image storing section which includes a memory for temporarily storing the imamge signal in accordance with the output signal of the integrator, so as to cancel the image fluctuation. The centering controller increases the rate of attenuation of the output signal from the integrator when such output signal corresponds to a value as large as one-half of a variable range of the shift of the read out position of the image signal from the image storing section.
