Title: Magnetic recorder and reproducer
Inventor: HIRAKURI SEISUKE
IPC: G11B20/22
Filed: 1982-01-16
Abstract: PURPOSE:To obtain a sound signal without distortion, by taking a pilot signal as a carrier wave, amplitude-modulating signals with a control signal, recording and reproducing the signals on/from a single track, and eliminating the frequency modulation of sound signals by means of the frequency fluctuation of the pilot signal. CONSTITUTION:A modulated wave of amplitude-modulation reproduced from a control track on a magnetic tape is demodulated at a demodulator 32 and the control signal is outputted from an output terminal 35. On the other hand, the modulated wave is formed into an impulsive pilot signal, about 480Hz in frequency via a switch SW, converted into a pulse, about 80Hz in frequency at a frequency-divider 38 and applied to a PLL40. The frequency fluctuation (wow and flutter) is detected at the PLL40, the result is applied to a VCO41 and a clock pulse is generated. The clock pulse varies a delay time of BBDs 52, 53 to eliminate the fluctuation from the sound signals from terminals 46 and 47.

Title: Image processing method and character recognition method
Inventor: SUINO TORU
IPC: G06T5/00
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To provide an image processing method and a character recognition method by which background data with a high density higher than that of low contrast character data can be removed. SOLUTION: A density conversion section 2 converts image data with a linear reflectance from an image input section 1 into image data with a linear density. In this case, the density conversion section 2 converts the image data into the image data with the linear density, in such a way that a constant output can be obtained with respect to an input range, where the density of background data with a high density is overlapped with the density of low contrast character data. An edge processing section 3 calculates the amount of edge and outputs data, in response to the edge amount so as to give the density difference between the density of the high density background data and the density of the low contrast character data.  A background elimination section 4 sets '0' to the density of the high density background data with a prescribed density or below, and provides a resulting output to remove the background data.
