PURPOSE:To make it possible to perform autoradiograph analysis with high accuracy and good efficiency, by performing proper signal processing by imparting necessary informations relating to various strains of the digital signal corresponding to an autoradiograph. CONSTITUTION:A mixture of four kinds of base specific DNA segments having radioactive labels applied thereto is separated and developed on a gel support medium by electrophoresis and the positional informations of said segments are obtained as digital signals. When offset strain is generated in separated and developed patterns, the peaks of each band are displayed on a picture as spots in a superposed state and an a cursor point is aligned with the arbitaray band position on a lane generating offset strain to confirm said position and moved upwardly or downwardly along a lane direction with respect to a fundamental lane to be fixed at a proper position. By this operation, correction information to offset strain is inputted.
