Abstract
Upon production of a reproduced picture from an original picture having a standard or non-standard, tonal conversion of the original picture is conducted based on pictorial information from the original picture. The information is processed in such a way that the base density information datum of a desired control point on the original picture and the halftone intensity at a corresponding control point on the reproduced picture are correlated in accordance with a specific conversion formula.
