Median Filter Interpolator

Standard Resolution Mode

The median filter interpolator converts RGB triplets received from the frame buffer to an 800 x 600
(standard resolution for the PDC-2000) RGB image by arranging the pixels and averaging
adjacent horizontal pixels as shown in Figure 2-2. It sends the reconstructed pixel data to the
SCSI interface.
