Color image correction device for correcting phase and resolution characteristics of a copy image using different color signal components

A color image reading and compensating device comprising:

• image reading means including a color image sensor unit having three line sensors arranged in parallel and corresponding to at least three colors R, G, and B, each of said line sensors being formed of a number of pixels arranged in a line, said image reading means reading a color image for outputting a color image signal having a plurality of color signal components corresponding to the colors R, G, and B and forming a pixel;
• first compensating means for compensating phase and resolution characteristics of the color image signal, by use of not only one color signal component selected from the color signal components of the color image signal but also the other color signal components, said one color signal component and said the other signal components being output from a pixel of interest and pixels near thereto;
• conversion means for converting the color image signal output from said first compensating means into a plurality of color code signals corresponding to the colors R, G, and B forming of the color image;
• and second compensating means for converting a color code signal corresponding to a specific pixel into the other color code signal in accordance with a predetermined rule.
