Abstract
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.

Claim 2
Dependent Claim
181 words
A color image reading and recording apparatus, comprising: three light sources corresponding to blue, green, and red colors disposed at one side opposite to a side of an original to be read; CCD image sensor means for obtaining signals, each signal representing a blue component, green component or red component, said CCD image sensor means sequentially lighting up and driving said three light sources and receiving light reflected from said original only once during a reading and recording operation; memory means for storing said signals representing said blue component, green component and red component; color converter means for converting the stored color component signals into yellow, magenta, cyan and black color signals; means for recording the color signals converted by said color converter means onto a recording paper; first control means for controlling the recording means to record yellow, magenta, cyan and black color images onto a recording paper in response to the color signals; and second control means for controlling the recording means to record single individual color images onto individual recording papers in response to the individual color signals.
Claim 3
Dependent Claim
150 words
A color recording method for a color image reading and recording apparatus, comprising the steps of: (a) selecting light sources corresponding to blue, green, and red colors; (b) positioning said light sources opposite an original to be read; (c) sequentially lighting said light sources; (d) receiving light reflected from said original; (e) obtaining signals corresponding to blue, green, and red components of the light received in said step (d); (f) storing said signals obtained in said step (e); (g) converting said stored signals of said step (f) into color signals corresponding to yellow, magenta, cyan, and black; (h) recording said color signals of said step (g) onto a same recording paper without repeating said steps (a) through (f); and (i) recording each individual color signal of said step (g) onto a separate individual recording paper without repeating said steps (a) through (f), thereby producing five recorded copies of said original.
Claim 4
Dependent Claim
