Title: Luminance signal/chrominance signal separation filter with correlative correspondence of image
Inventor: KASEZAWA TADASHI
IPC: H04N9/78
Filed: 1987-05-28
Abstract: PURPOSE:To reduce the influence of the leakage of a luminance signal and a chrominance signal to mutual channel at an area where an image changes remarkably and to reduce dot disturbance, by using a luminance signal/chrominance signal separation filter appropriately based on the correlation of a composite video signal in a vertical and a horizontal directions. CONSTITUTION:A composite color TV signal supplied to an input terminal 1 is sampled at an A/D converter 4. And in the sampled signal, a sample value at a remarked sampling point and the sample values at the sampling points at a picture one line above and one line under are extracted simultaneously by passing through delay circuits 5a and 5b. And extracted sample values are supplied to a vertical direction chrominance signal extraction filter 6a, a horizontal direction chrominance signal extraction filter 6b, a horizontal and vertical direction chrominance signal extraction filter 6c, and an image correlation decision circuit 7. The decision circuit 7 detects the correlation of the image with respect to the remarked sample point in the vertical and horizontal directions, and a switch circuit 8 is switched so that the output of the filter 6a can be selected when the correlation in the vertical direction is large especially, and the output of the filter 6b can be selected when correlation in the horizontal direction is large, and the output of the filter 6c can be selected in other cases.

Title: Wavelength control system in communication network, and wavelength multiplex communication network
Inventor: MAJIMA MASAO
IPC: H04B10/07
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To shorten the time needed to reach specific wavelength from the start of light emission by deciding that tentative light emission start wavelength at a non-zero wavelength distance from the other end of a wavelength range is a vacant wavelength free of interference with light signals of other optical nodes having already emitted light and allowing an optical node which makes a communication request to newly start emitting light with the tentative light emission start wavelength. SOLUTION: Wavelength arrangement is controlled to arrangement having prescribed wavelength intervals Δλ in the order of optical transmitters OT3, OT7,..., of an optical node, having started emitting light on the short-wavelength side (left side) of the wavelength range of a wavelength multiplex communication system, and when vacant wavelength (having an interval twice as large as Δλ) is generated owing to a stop of light emission, the light emission wavelength of its long wavelength side (right side) is shifted to the short-wavelength side to obtain arrangement from the short-wavelength side. Thus, the free wavelength can be controlled to the long wavelength side.  An optical transmitter OT5 of the optical node starts emitting light first in the center of the wavelength range of the wavelength multiple communication system and starts emitting light on the long-wavelength end, when the wavelength is not a free wavelength.
