(54) Color contact image sensor.
(57)
A color contact image sensor is a device for
sensing a character, a diagram, and a drawing
on a colored document and transmitting a sensed signal. The color contact image sensor
comprises a dot cell array composed of dot
cells having sensing elements for sensing red,
green and blue color components, so as to
sense color information printed on a point of a
document. Red, green and blue color component sensing signals generated by the dot cells
are sequentially supplied to a signal outputting
portion under the control of a driving portion,
and the signal outputting portion converts the
red, green and blue color component sensing
signals into digital data.
