ABSTRACT:
Apparatus and method for calibrating a display, such as a raster display, copier, liquid crystal display (LCD) or a printer is disclosed. The processor, under the control of an algorithm, generates adjustment images with a symbol that appears light on dark when misadjusted in one direction; dark on light when misadjusted the other way; and disappears at the point when the display is adjusted correctly. The invention can be used to calibrate brightness, color, gamma and sharpness.
