Patent ID: 8330758

Claim:
A method for processing waveform information to update an image being displayed on a display device, the method comprising: receiving sampled waveform data to be rendered as an image on a display device; associating at least a portion of the sampled waveform data with a pixel of the display device to form an image of the portion of the sampled waveform data; receiving state information for the pixel, the received state information comprising a value corresponding to one of a finite number of available states, each state defining a parameter for controlling display of the pixel; providing a transition probability vector (TPV) comprising a plurality of predetermined threshold values corresponding to the available pixel states; comparing a substantially random value to the predetermined threshold value that corresponds to the received state information for the pixel; updating the pixel state based on a result of the comparison; and, storing a control signal for controlling the pixel on the display device according to the updated pixel state; wherein the predetermined threshold values in the TPV are defined substantially so as to reduce the probability of a transition as pixel intensity approaches visual saturation.
