CCD Linear Image Sensor
MN3672RE
(Preliminary)
Color CCD Linear Image Sensor
with 5000 Bits each for R, G, and B Colors
Overview
The MN3672RE is a high speed high responsivity CCD color linear
image sensor with 5000 pixels for each of the colors R, G, and B.
This device consists of a photodetector region having low dark output
floating photodiodes and a CCD analog shift register in the read out
region.
It is possible to read out an A3 size color document with a high
quality and a high resolution of 400dpi.
Features
5000 floating photodiodes for each color R, G, and B, and an n-
channel buried type CCD shift registers for read out are integrated
in a single chip.
Since the photodiode lines for each color are neighboring (with a
line spacing of 14µm), it is possible to greatly reduce the memory
for compensation between lines.
The configuration of the signal processing circuits such as the
preamplifier, sample and hold circuit, etc., becomes simpler since
the separate signal output pins are provided for the pixels of each of
the colors R, G, and B.
RGB primary colors type on chip color filters are used for color
separation.
The dark signal output voltage has been suppressed to a very low
level due to the use of photodiodes with a new structure. (0.2mV
(typ.) at accumulation time of 10ms.)
Large signal output of typically 1.0V at saturation can be obtained.
Operation with a single +12V positive power supply.
Application
Color graphic read out in color copying machines, color scanners,
and color fax machines.
