ABSTRACT:
A method for centering and dimensioning an image on a cathode ray tube receiving display signals supplied by a display calculator includes measuring durations of vertical black edges of the image, and modifying adjustment values for a horizontal centering of the image to obtain equal lateral vertical edges. The method further includes measuring the durations of the vertical black edges of the image to calculate adjustment values for a horizontal dimension of the image to cause the vertical black edges to disappear. Durations of the horizontal black edges of the image are measured to calculate adjustment values of a vertical dimension of the image, and to calculate adjustment values of a vertical centering of the image to cause the horizontal black edges to disappear for centering the image vertically. The adjustment values obtained are recorded in a memory of the display calculator.
