ABSTRACT:
A starburst processor for providing dot flare and for use with a system having a means for generating graphic data for a set of logical pixels to be displayed on a display having a set of physical pixels. The starburst processor receives a set of commanded intensity values which has a one-to-one correspondence with the set of logical pixels. The system provides the set of commanded intensity values for the graphic data to be displayed. The starburst processor provides a set of actual intensity values which have a one-to-one correspondence with the set of physical pixels, each selected actual intensity value being a function of commanded intensity values for a predetermined neighborhood of logical pixels including a selected logical pixel corresponding to the selected actual intensity value. The neighborhood is a set of logical pixels which correspond to the set of commanded intensity values. For example, the neighborhood can include a selected logical pixel and all logical pixels adjacent to the selected logical pixel. Other neighborhoods can be defined depending upon the type of dot flare which is desired. From the neighborhood of commanded intensity values the starburst processor provides a selected actual intensity value for a selected physical pixel in the display which corresponds to a selected logical pixel. This actual intensity value is assigned a value from a predetermined plurality of different values.
