System, method and apparatus for pattern recognition with application to symbol recognition and regeneration for a caligraphic display

摘要

A display system apparatus comprises: a display device comprising at least a two-dimensional array of display pixels; at least one two-dimensional image memory that stores pixel values that reflect a specific display image; refresh circuitry that refreshes the display device from the pixel values stored in the at least one two-dimensional image memory; a signal input set comprised of at least one input signal; a pattern recognition apparatus that recognizes the symbols of a first symbol set from the signal input set and further comprising an output that identifies recognized symbols of the first symbol set; a rendering circuit that independently renders any of the symbols of a second symbol set into the at least one two-dimensional image memory; a plurality of memory tables residing within at least one physical memory device; addressing circuitry that derives a sequence of address values from the signal input set and applies the sequence of address values to address inputs of a corresponding sequence of memory tables from the plurality of memory tables to perform a sequence of memory table-look-up operations for producing a result that comprises the output that identifies recognized symbols of the first symbol set, and interfacing circuitry that, in response to the output from the pattern recognition apparatus, commands the rendering of symbols from the second symbol set by the rendering circuitry. The variation over time of input values for the signal input set reflects symbols for display on the display device. The signal input set comprises an analog X deflection input, an analog Y deflection input, and at least one video input signal. A recognised symbol of the first symbol set results in the rendering of an associated symbol from the second symbol set. (62) Divided out of 520196
