ABSTRACT:
A method for use in a raster-scanned electron beam display for displaying an image signal. The image signal is clocked out of a store at a variable clock rate correlated with beam location. The image signal is impressed on the electron beam in order to control image size, position or geometry. The variable clock rate is developed from stored instructions.
