ABSTRACT:
A color image reading and recording apparatus comprises three light source corresponding to blue, green and red colors disposed at one side opposite to the side of the original to be read. A CCD image sensor is used to obtain signals corresponding to the blue, green and red components of the original through the sequential lighting up and driving of the three light sources. The CCD image sensor receives light reflected from the original. A memory device is used to store color component signals corresponding to the blue, green and red components. A color converter then converts the color component signals into yellow, magenta, cyan and black. The apparatus further records the colors converted by the color converter onto a recording paper by controlling the recording of the yellow, magenta, cyan and black color images onto the same recording paper. Also, the apparatus records the single color images obtained by combination of specified color component signals stored in the memory device onto individual recording papers.
