Abstract

PURPOSE: To read characters while discriminating colors of respective characters by using lightness signals to make signals of binaries and discriminating colors of characters and determining character colors by a count value on a basis of a logic determined previously.
CONSTITUTION: Character 2 on recording carrier paper 1 is scanned by color scanning unit 4 through optical system 3 to obtain color separation signals R, G and B. Chromaticity coordinates r and g on grid points are calculated from these signals by chromaticity coordinate calculation circuit 5, and further, these coordinates are caused to pass through color discrimination circuits 6-1, 6-2 and 6-3 to discriminate a color to which they belong, and output signals CA, CB and CC which become 1 for belonging and become 0 for non-belonging are obtained. Meanwhile, G components out of outputs of the unit are defined as a lightness signal and are caused to pass through quantizing circuit 7 to obtain binary pattern P. Signals CAWCC are masked with pattern P by AND gates 8-1W8-3 to obtain CA'WCC'. These signals are counted by counters 9-1W9-3 for every grid point to obtain NAWNC, and they are compared with one another by color discrimination circuit 10 after the end of scanning for one-character components, and components having a maximum value are discriminated as the color of the character, and color signal S is outputted.
