ABSTRACT:
Corrective line quantities for compensating for differences between reading positions in an auxiliary scanning direction of linear image sensors of a 3-line image sensor are determined, and the determined corrective line quantities are divided into integer-part corrective line quantities and decimal-part corrective line quantities. The decimal-part corrective line quantities are interpolated in real-time by a hardware arrangement from preceding image data and presently read image data, using line buffer memories. The integer-part corrective line quantities are changed in addresses when they are stored as a file in a hard disk or the like, thus providing image data which are equalized in reading positions.
