We developed a new 7M-pixel Type
1/1.8 CCD image sensor to respond
to new demands for high-quality
moving picture in addition to the
higher pixel counts and miniatur-
ization previously demanded by the
digital still camera market. This
new image sensor will allow digital
still cameras to provide not only
still picture, but high-quality mov-
ing picture as well. I hope you will
seriously consider developing new
consumer digital still camera prod-
ucts that take advantage of the fea-
tures of this device.

High-Resolution 7.24M-Pixel Diagonal 9.107 mm (Type 1/1.8) Color CCD
for Consumer Digital Still Cameras Supports VGA Moving Picture Imaging
ICX489AQF
The demands for higher pixel counts and further miniaturization con-
tinue to increase in the rapidly growing digital still camera market.
To respond to these demands, Sony has developed the ICX489AQF
diagonal 9.107 mm (Type 1/1.8) CCD image sensor that features 7.24M
effective pixels.
The ICX489AQF takes full advantage of the latest fine fabrication tech-
nologies to achieve a 2.35
μ
m unit pixel size. This results in both higher
resolution and further miniaturization.
Sony's unique horizontal and vertical pixel addition technology allows
the ICX489AQF to provide both 7M-pixel still picture and 30 frames/s
VGA moving picture imaging.

The ICX489AQF is a 7.24M-effective
pixel diagonal 9.107 mm (Type 1/1.8)
CCD image sensor that was developed for
use in high-resolution consumer digital
still cameras. It provides high-resolution
image capture when a mechanical shutter
is used. Figure 1 presents Sony’s lineup
of CCD image sensors for consumer digi-
tal still cameras. Since the ICX489AQF
is positioned as a higher pixel count
version of the earlier Sony ICX455AQF
(diagonal 9.04 mm (Type 1/1.8), 5.13M
effective pixels) product, it allows a 7M-
pixel digital still camera to be imple-
mented based on an earlier ICX455AQF
camera without changing the optical sys-
tem. Table 1 lists the ICX489AQF device
structure, and table 2 lists the imaging
characteristics.
High Saturation Signal
The ICX489AQF adopts a 5-field readout
method to improve the dynamic range and
resolution in moving picture mode. This
allows the area occupied by the photodiode
block in the unit pixel to be increased and
allows the ICX489AQF to provide a satu-
ration signal of 385 mV.
High Sensitivity
The light collecting ability of the indi-
vidual pixels has been improved by opti-
mization not only of the fine fabrication
technology used for the on-chip
microlenses, but also of the shape of the
microlenses, and by the adoption of thin-
film primary color filters. These technolo-
gies allow the ICX489AQF to achieve a
sensitivity of 168 mV despite a pixel size
of 2.35
μ
m.
Timing Generator IC
Sony also provides the CXD3630GA
timing generator IC that includes built-in
horizontal and vertical drivers for the
ICX489AQF. In addition to a VGA
equivalent moving picture mode, this IC
also supports a high frame rate readout
mode and an AF mode as well.
