Claims
- 1. A multi-color image reading apparatus comprising:
- photoelectric converting means for providing plural color separation signals corresponding to plural color-separated light beams from a multi-color image;
- color identifying means for forming plural color signals, corresponding to colors of said multi-color image, from said plural color separation signals;
- correcting means for correcting at least one of said color signals, said correcting means being adapted to utilize a color signal of a determined color for correcting other color signals; and
- expanding means for expanding the color signal of said determined color, wherein the expanded color signal of said determined color is utilized for correcting other color signals.

- 4. A multi-color image reading apparatus according to claim 1, wherein said expanding means comprises means for delaying the color signal of said determined color for a determined amount.
- 5. A multi-color image reading apparatus comprising:
- photoelectric converting means for providing plural color separation signals corresponding to plural color-separated light beams from a multi-color image;
- color identifying means for forming plural color signals corresponding to the colors of said multi-color image from said plural color separation signals;
- delaying means for delaying one of said plural color signals formed by said color identifying means; and
- correcting means for correcting at least one of said plural color signals, said correcting means responsive to the delayed color signal to erase an erroneous color signal formed by said color identifying means.
- 6. A multi-color image reading apparatus according to claim 5, wherein said correcting means is adapted to utilize a color signal of a determined color for correcting other color signals.
- 7. A multi-color image reading apparatus according to claim 5, wherein said correcting means erases an erroneous color signal that is formed at level-changing points of said at least one of said plural color signals.
