Patent ID: 7079143

Claim:
A method for waveform drawing to reduce waveform flicker arising from drawing a successor image after a drawn predecessor image, comprising: receiving an array of predecessor image data points, the array of predecessor image data points containing a predecessor high end point and a predecessor low end point, defining an upper bound of a predecessor line and a lower bound of the predecessor line, respectively, wherein each element of a domain of the predecessor array corresponds to a horizontal displacement and each element of a range of the predecessor array corresponds to a vertical displacement; receiving an array of successor image data points, the array of successor image data points containing a successor high end point and a successor low end point, defining an upper bound of a successor line and a lower bound of the successor line, respectively, wherein each element of a domain of the successor array corresponds to a horizontal displacement and each element of a range of the successor array corresponds to a vertical displacement; comparing the high end point and low end point of the successor line to the high end point and low end point of the predecessor line, respectively; and maintaining portions of the predecessor line on a display that are determined in the comparing step to intersect with the successor line.
