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 digital 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 implemented based on an earlier
ICX455AQF camera without changing the optical
system. 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 saturation signal of 385 mV. |
|
High Sensitivity |
|
The light collecting
ability of the individual pixels has been improved
by optimization 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 technologies allow the ICX489AQF to achieve
a sensitivity of 168 mV despite a pixel size
of 2.35 µm. |

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. |

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 miniaturization
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 moving picture as well. I hope
you will seriously consider developing new consumer
digital still camera products that take advantage
of the features of this device. |
