Abstract: At a smoothing spectrogram calculation portion, a triangular interpolation function having a frequency width twice that of the fundamental frequency of a signal is obtained based on information on the fundamental frequency of the signal. The interpolation function and a spectrum obtained at an adaptive frequency analysis portion are convoluted in the direction of frequency. Then, using a triangular interpolation function having a time length twice that of a fundamental period, the spectrum interpolated in the frequency direction described above is further interpolated in the temporal direction, in order to produce a smoothed spectrogram having the space between grid points on the time-frequency plane filled with the surface of a bilinear function. Using the smoothed spectrogram, a speech sound is transformed. Therefore, the influence of periodicity in the frequency direction and the temporal direction can be reduced.

Abstract: An input/output control mechanism receives facial image information of different facial expressions of a plurality of human beings to provide control so that a normalization processing mechanism normalizes each facial image information. A facial expression generation mechanism converts the normalized facial image information into facial expression components, and averages the facial expression components for each facial expression to store the same as average facial expression components. The input/output control mechanism has the facial expression component converted by the facial expression generation mechanism after the applied facial image information is normalized.

Abstract: A number of cells each having a state storage mechanism and a state update mechanism are arranged in the form of a grid. The state storage mechanism includes parts opening and closing information to the remaining cells, and the state update mechanism includes open and closed update parts. The state update mechanism decides the next state on the basis of its own cell state and open states of neighboring cells.

Abstract: A speech signal input from a microphone is distributed by a distribution amplifier. Using output signals of a filter group of cos phase having cut-off frequency moderate on low frequency side and steep on high frequency side and of similar filter group of sin phase, stability index is calculated based on magnitude of amplitude modulation and magnitude of frequency modulation of the signals, by stability index calculating portion and fundamental frequency extracting portion. Based on the result of calculation, approximate value of fundamental frequency is calculated based on an output of a channel indicating maximum stability, and based on the approximate value of fundamental frequency, instantaneous frequency extracting portion extracts precise instantaneous frequency as fundamental frequency, interpolating value of instantaneous frequency from adjacent frequency channels.

Abstract: When right and left images are presented on a projection plane which is a display plane with binocular disparity, an object located in front of projection plane P.sub.s can be perceived at the right position by accurately calculating the corresponding points while avoiding vignetting due to the picture frame of projection plane P.sub.s or by making it appear as if an occluding object at the frontmost plane (i.e. virtual frame VF) were present.

Abstract: In an adaptive cross correlator apparatus, a first receiving section receives a signal and outputs the received signal as a first signal, and a second receiving section receives a further signal and outputs the received further signal as a second signal, wherein the second receiving section is provided at a position different from that of the first receiving section. A first filter filters the first signal with a first changeable transfer function and outputs a filtered first signal, and a second filter filters the second signal with a second changeable transfer function and outputs a filtered second signal.

Abstract: When information representing an application problem is entered from an input unit, a hardware specification interpretation unit calculates an operation result representing how the consequent hardware operates with respect to the application problem according to the information representing the application problem and the hardware specification description provided from the hardware specification description unit. A fitness calculation unit calculates a fitness representing how much the calculated operation result fits the application problem. A description modification unit modifies the current hardware specification description on the basis of a fitness evaluation which is the calculation result.
