Abstract: PROBLEM TO BE SOLVED: To provide a device for the filtering of video images for effectively performing image filtering following the problems of noise attenuation, space/ time resolution and wide luminance change. SOLUTION: This device is provided with first input terminals PFy and PFuv, second input terminals DFy and CFuv and output terminals corresponding to the output terminal of the device respectively. Further, the device is provided with first and second circuit parts 3 and 4 provided with mutually cascade- connected first filter 5, second filter 6, third filter 8 and forth filter 9 and the first filter 5, the second filter 6 and the third filter 8 are provided with a calculation circuit means for processing a digitized luminance element Y by using a fuzzy theory. Further, the forth filter 9 is provided with the calculation circuit means for processing digitized chrominance elements U and V based on a parameter knr supplied from the second filter 6.

Abstract: PROBLEM TO BE SOLVED: To provide a method for recognizing a geometrical shape in an image by using the fuzzy logic. SOLUTION: This method includes decision of edges and gradation of the edges in an image. The gradient is corrected by a 1st fuzzy logic process and number of points included in a curve is decided by a 2nd fuzzy logic process. A fuzzy device to recognize a geometrical shape in the image to realize this method includes an edge detector 3, a fuzzy gradient correction device 5 to correct the gradient and a fuzzy boat attributer 6 to decide number of points included in a curve.
