Filed: 2004-03-19
Abstract: <P>PROBLEM TO BE SOLVED: To prevent the separation of an elastic layer from an underlayer caused by air retained in a pavement structure with the elastic layer coated on the underlayer comprising an asphalt mixture.  <P>SOLUTION: A subbase course 1, a base course 2, a foundation course 3 consisting of a permeable asphalt mixture, a surface layer 4 consisting of an impermeable asphalt mixture, an unevenness adjustment layer 5 for adjusting the surface of the surface layer 4 levelly, and the elastic layer 6 formed of resin plate members, are sequentially layered.

IPC: H04N1/58
Filed: 2004-03-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a video signal processing system for uniformly correcting a contour in the whole area of an image, while correcting shading, and to provide an electronic video apparatus.  <P>SOLUTION: A noise reduction filter circuit 14 uses a numerical value, which is changed in proportion to gain g to be used for correcting shading, i.e., a distance from the center of a screen, for a noise reduction filter processing. Consequently, the noise reduction filter processing is not performed in the center part of the image without noise by shading correction, so as not to affect image quality. On the contrary, the gain value of the shading correction is larger in the peripheral part of the image. Then the effect of a noise reduction filter becomes larger in an emphasized noise, so as to sufficiently remove the noise.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
