Low resolution raster images

摘要: The present invention enhances the resolution and quality of characters a system receiving information initially in form video display pixels providing hard copy output. This is accomplished by storing at least three successive lines data successive, parallel connected shift registers, applying outputs registers to decoder, generating driving signals for printer head. decoder compares on same line as well preceeding succeeding that surround each specific input pixel generate head according whether straight or curved segments are be formed. In effect, increases density elements simultaneously provides rounding off character edges smoothing diagonals.
