1. Line information is read by CIS (to be used as the reference white
level) via route1, and is input to IC501. Refer to
2. In IC501, the data is adjusted to a suitable level for A/D
conversion in the Analog Signal Processing Section, and via
route2 it is input to A/D conversion (8 bit). After finishing A/D
conversion, the data is input to the Image Processing Section via
route3. Then via route4 and route5, it is stored in RAM as shading
data.
3. The draft's information that is read by CIS is input to IC501 via
route1. After it is adjusted to a suitable level for A/D conversion
via route2, the draft's information is converted to A/D (8 bit), and it
is input to the Image Processing Section. The other side, the
shading data which flows from RAM via route6 and route7, is
