摘要： An imaging apparatus measures shake of the apparatus using a gyro sensor, performs “a center stop control” until receiving an instruction to start recording the still picture, and performs “a lens correction control” after the start of exposure in the imaging apparatus. The center stop control controls the correction lens position to stop a correction lens at an optical axis center position (position of the correction lens at which an optical axis of the imaging lenses coincides with an optical axis of a correction lens). The lens correction control controls the correction lens position to correct blurring of the image formed on an imaging element based on the measuring result. The imaging apparatus returns the correction lens to the optical axis center position before receiving a next instruction to start a next recording, and then performs the center stop control on the correction lens.

摘要： A spread spectrum signal demodulator receives a received signal including a plurality of spread spectrum signals, and comprises at least one signal strength suppressing means, which reduces a correlation signal outputted from a first correlation detecting means or replica signals until the correlation signal has been traveled through a replica signal generating means, a replica signal subtracting means and a second correlation detecting means. According to the invention, it is possible to improve interference cancellation capacity with a computational effort substantially comparable to that in a prior art replica signal cancellation system and improve interference cancellation performance with increasing number of interference cancellers irrespective of the magnitude of the correlation. With a sufficient number of interference cancellers provided, it is possible to obtain the same effect as obtainable with prior art decorrelation in a real time processing irrespective of the correlation magnitude.

摘要： In radio communication with non-modulated signal at head of receive signal, the non-modulated signal or the head of the receive signal is detected in spite of rather large frequency error of receive signal, and frequency acquisition for coherent detection in a receiver is established during detection operation of the non-modulated signal Discrete Fourier Transform (1) is carried out for an input signal in digital form in every receive sample to provide frequency spectrum of an input signal. Then, the maximum component is selected (2) in the frequency spectrum. Next, a peak detector (3) detects peak value of the selected maximum components on time axis, and recognizes the detection of the non-modulated signal. The frequency (f.sub.e) of the non-modulated signal is estimated through interpolation of the selected component having the peak value and the adjacent component. The receive frequency is adjusted by using said estimated frequency (f.sub.e), and the adjusted frequency is subject to coherent detection.
