2.2.4.4 Scan
1) Pictorial signal input part: output signal of CIS passes through MP Cap change to ADC at LAFE1001, and
defined signal between LAFE1001 and JUPITER5 processes the Image signal. When AFE accepts each
pixel, CDS (Correlated Double Sampling ) technique which samples arm-level twice is used on each pixel
by the CIS signal.
2) The image processing portion is read by CIS Pixel data in 1200dpi Line and processed using an Error
Diffusion Algorithm on Text mode and Photo mode. When scanning at machine and/or on PC Scan, the
data is stored in a Scan Buffer without algorithm.
Shading and Gamma Correction are executed immediately in every mode, then processing is executed
later.
