ABSTRACT:
The present invention is situated in the presence of an image source having an image and a display device having an image alignment register, a pixel address, and a pixel signal, the display device coupled to the image source. The apparatus of the present invention preferably comprises a pixel level comparator, a computer, and a pixel detection unit. The pixel level comparator is for setting a pixel detect signal to true if the pixel signal exceeds a threshold. The pixel level comparitor is coupled to the display device. The computer has a selected address and is coupled to the image alignment register. The pixel detection unit is for setting a pixel data signal to true if, while the pixel address and the selected address are equivalent, the pixel detect signal is set to true. The pixel detection unit is coupled to the display device, the pixel level comparitor and the computer. The method of the present invention is situated in the presence of a system including an image source having an image comprised of a plurality of image columns and a display device having a plurality of display screen columns. The method preferably comprises the steps of collecting pixel column address pixel presence signal data corresponding to the plurality of image columns and aligning the plurality of image columns within the plurality of display screen columns.
