Title: Ultralow frequency sound compensation system and acoustic device using it
Inventor: INAGAKI RYOSUKE
IPC: H04R3/12
Filed: 2000-03-01
Abstract: PROBLEM TO BE SOLVED: To solve the problems that a conventional ultralow frequency sound compensation system is limited in low frequency sound reproduction quality with a small-sized speaker or the like whose low cut-off frequency is high because only a gain at a low sound frequency is amplified and causes a reproduction sound apart from the substantial ultralow frequency sound when the entire low sound frequency is uniformly amplified. SOLUTION: In the ultralow frequency sound compensation system, an LPF 13 extracts a low frequency component of a sound signal received from a sound source, a harmonic tone circuit section 14 shifts the low frequency component to a frequency band being a multiple of 2n of the original frequency band and the amplitude is increased to a multiple of 2n of the original amplitude and the resulting signal is added to the original sound signal. Furthermore, the harmonic tone circuit section 14 is a series connection circuit consisting of n-sets of analog multipliers 14a.

Title: Scene characteristic detection type moving picture coder
Inventor: NAITO HITOSHI
IPC: H04N19/134
Filed: 2000-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a scene characteristic detection type moving picture coder that can reduce deterioration in image quality on the occurrence of a scene change point as much as possible. SOLUTION: A time space area filter 4 updates a filter characteristic (that is, a filter coefficient) on the basis of scene attribute information (a) outputted from a scene change point detection section 3a and coding difficulty information (b) outputted from a coding difficulty estimate section 3b. When the coding difficulty is high through this updating, a high frequency component of an image signal can be reduced. A rate control section 5 decides an object code quantity on the basis of the scene attribute information (a) and the coding difficulty information (b). The object code quantity of the image signals within a prescribed distance from the scene change point is weighted by a weight coefficient Wsc (>1.0) depending on the coding difficulty.  As a result, the code assigned quantity with respect to the image signals is increased to suppress deterioration in the image quality at the scene change point.

Abstract: PROBLEM TO BE SOLVED: To provide an azimuth measuring apparatus in which a phase detection of good linearlity is executed by processing a digital signal, in which an azimuth can be measured by a simpler calculation and in which a sinusoidal signal can be regenerated precisely. SOLUTION: An azimuth antenna 2 scans a plurality of antenna elements arranged at equal intervals on the circumference of a circle sequentially at a prescribed rotation frequency. An A/D converter 17 converts signals from the respective antenna elements into digital signals. An A/D converter 16 converts a reference signal from a receiving antenna 1 into a digital signal. A phase detector 18 multiplies the signals, from the respective antenna elements, to be output from the A/D converter 17 by the reference signal to be output from the A/D converter 16 so as to be phase-detected, and it obtains the rotating sinusoidal signal containing a rotation frequency. An FFT processing part 21 performs a fast Fourier transform processing operation while an azimuth reference signal is used as a frame starting point with reference to the rotating sinusoidal signal.  An azimuth-angle calculation part 23 finds the arrival direction of received radio waves based on the azimuth angle of a frequency component vector corresponding to the rotation frequency within a spectrum in an FFT output.
