Abstract
Light beams scans patterns of a subject copy, being reflected therefrom, and being converted into pulsating electrical signals. Color borders between two different colored patterns are detected based on the pulsating signals. On the other hand, a color of a predetermined scanned line following each of the color borders is sensed for determining the sensed color as a color between the adjacent color borders.
