ABSTRACT:
A color image pickup apparatus has one line sensor which sequentially reads a document through different color filters to generate different color signals. Either the line sensor or the document is mechanically moved in a sub-scanning direction by a mechanical device. A rotary encoder coupled to the mechanical device generates pickup pulses which drive the line sensor each time the line sensor or document is moved a predetermined distance. In an alternate embodiment, two or more line sensors having different color filters each read a different line on the document to generate different color signals having shifted timings. Frame memories, shift registers, memories with a capacity of a plurality of lines, or buffer registers may be used to correct for the shifted timings of the color signals.
