Method and system for compensating the non-linearities in a reproduction process

摘要: A method of calibrating a reproduction apparatus having sensor device for generating signals by optically scanning picture original and recording controlled the on film, comprising steps: set first said to produce sample gray scale film predetermined range values; storing second corresponding respectively signals; third substantially values recorded scale; correlating fourth representing reference group at least some obtaining in storage addresses group, whereby generated signal given value can be used select from stored correlated suitable duplicate value. The invention also relates system apparatus.
