APC
APC (formerly known as Arithmos Perfect Color) dithers an input 10 bit video stream down to 4-8
output bits. The dithering is done in space and time in such a way that the eye does not perceive
objectionable artifacts such as:
q Fixed dither patterns
q Contours
q Flickering pixels
q Phase correlated flickering, which creates wave patterns known as “swimming”
