Abstract
A grey image value expansion method or system enables a receiving system to convert image data having a lower bit resolution to the higher native bit resolution of the receiving system. The conversion or expansion produces a new pixel byte which is a compilation of the received pixel byte wherein the received pixel byte has been repeated at least two times in the compilation. More specifically, a pixel byte having a bit resolution equal to A is converted to a new pixel byte having a bit resolution equal to B wherein the new pixel byte is a compilation of the received pixel byte. The received pixel byte is a unit of the new pixel byte such that the received pixel byte is repeated N times in the compilation wherein N being an integer equal to or greater than two. The number of repeating received pixel byte can be varied so long as N times A is less than or equal to B.
