20110188583 | PICTURE SIGNAL CONVERSION SYSTEM - A reverse filter operates for adding noise n(x,y) to an output of a deteriorated model of a blurring function H(x,y) to output an observed model g(x,y). The blurring function inputs a true picture f(x,y) to output a deteriorated picture. The reverse filter recursively optimizes the blurring function H(x,y) so that the input picture signal will be coincident with the observed picture. In this manner, the reverse filter extracts a true picture signal. A corresponding point is estimated, based on a fluency theory, on the true input picture signal freed of noise contained in it by the reverse filter ( | 08-04-2011 |

20110153704 | Filter - Provided is an FIR filter capable of obtaining predetermined characteristics with a small number of input taps, delay circuits, and multipliers and achieving an improved response and low cost. In a low-pass filter, a band-pass filter, and a high-pass filter based on an FIR filter, a basic filter is configured that gives a basic impulse response function and has a filter coefficient determined from the impulse response function. Filters having different frequency characteristics are configured by changing the time scale or frequency scale of the basic filter. These filters having different frequency characteristics are combined in a cascade form or a step form, thereby constructing an FIR filter having a small number of taps. | 06-23-2011 |
