Abstract: A method for setting up the memory of an electronic controller operates in Fuzzy logic, whereby predetermined membership functions (f(m)) of logic variables (M), defined within a universe of discourse (U) sampled in a finite number of points (m), are subjected to inference operations basically configured by IF/THEN rules with at least one front preposition and at least one rear implication. The controller further comprises a central control unit (3) provided with a memory section (5) for storing predetermined values (l) of the membership functions (f(m)) which appear in the front or IF part of the Fuzzy rules and have a predetermined degree of truth or membership (G). This method provides for storing into said memory section (5) the only values (l) of those membership functions (f(m)) which have a value (l) of the degree of membership (G) other than zero at the points (m) of the universe of discourse (U).

Abstract: The analog processor of this invention can carry out processings independently of the operating temperature and process parameters, in a reliable manner and at high performance levels using fairly simple circuitry. To achieve this independence, the processor is basically implemented and integrated with MOS transistors, has both voltage inputs (AI) and outputs (OUT), and includes a biasing section (BIAS) which supplies voltage bias signals (VG), of which at least one is substantially the sum of a voltage proportional to the threshold voltage of the MOS transistors and a reference voltage. This reference voltage can be extracted from a reference potential which is stable to temperature and process parameters, for example that produced by a bandgap type of generator. A major feature of the processor according to the invention is the linearity of its input-output characteristic relative to that reference voltage. It follows that it may be advantageous to extract that reference voltage by division from a signal indicating the width of the input signal variation range, thereby to achieve compensation for or independence of variations of this range.

Abstract: PROBLEM TO BE SOLVED: To suppress noise affected on a specific area of a field scanned by the unit of lines by replacing a pixel having noise with an average pixel value of a nearby pixel belonging to a prescribed processing window. SOLUTION: A difference calculation circuit calculates a difference Di (D1-D7) between luminance values Xi (X1-X7) of a pixel adjacent to a processing pixel value X of a processing window. Then a Dmax &Dmin detection block identifies a maximum value and a minimum value of a received difference Di. Upon the receipt of the Dmax and Dmin by an adaptive threshold level detection processing block adopting a 1st fuzzy logic, they are referenced as a membership 1 and corresponding values to the threshold levels Th1, Th2 are generated. Then a local adaptive noise smoothing processing block adopting a 2nd fuzzy block generates a set of output values Ki based on the threshold level parameters Th1, Th2 referenced by a membership 2 and generated before. A final filter block generates a pixel Xout as a sum of weighting factors.

Abstract: PURPOSE: To greatly reduce a storage area for storing belonging relation functions from the IF portion of a fuzzy rule and the calculation operation of a THEN portion by providing a conversion block in an input part and providing at least one memory block for storing information relating to the IF conditions of an IF-THEN rule set in the conversion block. CONSTITUTION: The conversion block 5 for forming this input part of an electronic controller operated in a fuzzy logic form is provided with the memory block 6 and the memory block 6 stores data relating to the belonging relation functions relating to the IF portion of the fuzzy rule. The memory block 6 is divided into an imaging area 7 and an activating area 8. The imaging area 7 is provided with the set of the belonging relation functions relating only to the IF conditions in the IF-THEN rule set and the activating area 8 is provided with the data for relating the respective logic variables of a fuzzy type relating to a control process to the corresponding ones of the belonging relating functions in the set.
