µPD8875
Color(A4)
(5400+5400) Pixels × 3 Color + (5400+5400) Pixels B/W
Overview
The µPD8875CY-A is a color CCD (Charge Coupled Device) linear image sensor that changes optical images to electrical signal. It has 3 rows of (5400 + 5400) staggered color pixels and (5400 + 5400) staggered pixels of black and white, and each row has dual-sided readout type of charge transfer register. And it has reset feed-through level clamp circuits and voltage amplifiers. Therefore, it is suitable for 1200 dpi / A4 color image scanners.
