The Industry’s First Digital Copier CCD Linear Sensor

with RGB Adjacent 3-Line Plus Monochrome 1-Line 7600-Pixel Sensors

ILX146K

Color RGB adjacent 3-line CCD +

monochrome (green) CCD

At the same time as demand for digitizing documents is increasing, there

is also rapid progress being made in switching from analog to digital in

copiers. The increasing performance in this area is remarkable.

Due to this background, there is now strong demand for CCDs that can

provide the performance to scan documents with high quality at even

faster speeds.

High-speed transfer

Maximum data rates:

100 MHz (monochrome)

150 MHz (color)

To respond to these needs, Sony has now developed the ILX146K CCD

linear sensor in which the RGB sensor lines are directly adjacent to each

other.

Device Structure

Since the ILX146K also provides a mono-

chrome (green) CCD, the ILX146K can

support high-speed black-and-white

scanning of documents and wide range of

signal processing.

High-Speed Transfer

Maximum Data Rates:

100 MHz (Monochrome),

150 MHz (Color)

Figure 1 shows the ILX146K block dia-

gram and figure 2 shows the structure of

the vertical transfer block of the color

RGB adjacent 3-line CCD.

Figure 3 shows the structure of the mono-

chrome CCD vertical transfer block.

While the color RGB adjacent 3-line CCD

has a 2-stage horizontal register structure

for each color, the monochrome CCD

adopts a 4-stage structure in the horizon-

tal registers for even faster processing.

Sony applied further refinements to the

color CCD vertical transfer structure, to

allow the signal charge to be divided

among 4 horizontal registers. The signal

charge transferred by the horizontal reg-

isters is transferred a maximum distance

of 7 cm (9.325 µm × 7,500 pixels) to the

charge to voltage conversion block. Each

of these horizontal registers has a maxi-

mum transfer rate of 25 MHz. This allows

the ILX146K to achieve a maximum data

rate of 100 MHz.

The color RGB adjacent 3-line sensor pro-

vides a vertical transfer gate adjacent to

the blue sensor and reads out the charge

collected at the green sensor. By carefully

controlling the drive timing of the read

gate and the vertical transfer gate, the read-

out charge is transferred to individual hori-

zontal registers without any mixing of the

blue and green charge. This allowed Sony

to create an adjacent RGB sensor and

made the following two features possible.

Suppression of Incorrect Color

Registration During Scanning

Mechanical motion is required for docu-

ment scanning using a CCD linear sen-

sor. When spatial read errors (variations

in the read position) in the scan direction

occur during this mechanical motion,

color registration errors occur. Since con-

ventional CCD linear sensors have a wide

spacing between the RGB sensors, the

possibility for read errors to occur is high,

especially during high-speed scanning.

Since the ILX146K, in which the RGB

sensors are adjacent, is resistant to the in-

fluence of spatial errors during scanning,

color displacement is suppressed and it

can support high-quality high-speed scan-

ning.

The ILX146K adopts a CCD trans-

fer structure that differs from

conventional sensors. We came

up with a lot of new ideas, for

example, in the drive timing, and

as a result were able to create a

CCD linear sensor that features

the 3 RGB lines being adjacent,

which was previously unknown.

This device is optimal for copiers

and other scanner-based end

products that need to operate at

high speed. I strongly recommend

that you consider this device.
