Title: Color mixture reducing circuit
Inventor: YAMAUCHI HIMIO
IPC: H04N9/07
Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To suppress signal level difference due to color mixture among adjacent homochromatic pixels and to reduce an alias of a contour signal by adding the signal of a left or right pixel to a certain pixel signal with a desired ratio. SOLUTION: A switching signal generating part 14d outputs an H level switching signal only when an index signal of a timing signal generating part generating a reference timing signal such as the driving of a sensor 11 is green and outputs an L level switching signal when it is a color except it. That is, when a sensor 11 output converted by an A/D conversion circuit 13 is a green pixel, an output of a D-FF circuit 14 becomes a red or blue pixel being a left adjacent one. The switching signal generating part 14d output gates an AND gate 14e so as to apply a constant (2α-2β) to a multiplier 14c at such a time alone. An adder 14a adds an output of the multiplier 14c to a converted output of the sensor 11 to obtain an output undergoing color mixture reduction.  Thus, it is possible to reduce an alias of a contour signal by applying the constant (2α-2β) to the left adjacent pixel of the green pixel.

Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To provide a weaving structure of a webbing in which a woven yarn is not projected to a surface side caused by a bending of a webbing and the phenomenon can be realized without sacrificing a strength and an energy absorbing property. SOLUTION: The webbing 10 is constituted by weaving a warp comprising a core yarn 16 and a ground yarn 18 and a weft. An elongation ratio of the core yarn 16 is smaller than that of the ground yarn 18 and an elongation rigidity of the core yarn 16 is larger than that of the ground yarn 18 and then a twist processing such as 'single twist' is carried out. Thereby, a convex/ concave is generated on a surface of the core yarn 16 and a friction between the core yarn 16 and other ground yarns 18 or the weft 14 is increased. The friction force between the yarns functions as a force for inhibiting a free movement of the core yarn 16 at the time of bending of the webbing 10 and it is prevented that the core yarn 16 is projected to the surface side of the webbing 10.
