Abstract
Distortion is minimized in displaying a waveform on a television display where the wave is identified by sequential magnitude points. The midpoint between consecutive magnitude points is determined, and raster line points in the television display are illuminated along the vertical axis from each magnitude point to the adjacent midpoint thereby minimizing the box-like image of complex waves.
Claims6
In a television display system in which video magnitude data is stored as digital data in a display memory for control of the television display, a method of controlling raster line display illumination for interconnecting first and second points identified by coordinates along two axes comprising the steps of
- identifying the midpoint along one axis between said first and second points,
- storing midpoint data for illuminating raster line points extending along said one axis between said first point and said midpoint, and
- storing data of said second point for illuminating raster line points extending along said one axis between said midpoint and said second point.
In a television display system in which video magnitude is stored as digital data in a display memory, apparatus for controlling raster line illumination for interconnecting two points identified by coordinates along two axes of a television display comprising a first memory for receiving and storing data identifying sequential points of a curve, first means interconnected with said first memory means for deriving the midpoint along one axis between adjacent points, a second memory, and second means interconnecting said first means and said second memory for storing raster line illumination data for raster line points extending along said one axis between a first of said two points and said midpoint and storing raster line illumination data extending along said one axis between the other of said two points and said midpoint.
