* "EXview HAD CCD II" is a trademark of Sony
Corporation. The "EXview HAD CCD II" is a
CCD image sensor that realizes sensitivity
(typical) of 1000 mV or more per 1 µm2
(Color: F5.6/BW: F8 in 1 s accumulation
equivalent) and improves light efficiency by
including near infrared light region as a basic
structure of Sony's "EXview HAD CCD".

The ICX694ALG and ICX694AQG are
diagonal 15.99 mm (Type 1) 6.09M-effective
pixel CCD image sensors designed for use
in industrial and scientific instrumentation
cameras.
They include multichannel output switching
and an extensive set of drive modes. |
 Extensive Set of Drive Modes |
|
Like the current Sony products, the
ICX674ALG and the ICX674AQG, by
changing the vertical and horizontal transfer
register drive timing according to the
required frame rate, the ICX694ALG and
the ICX694AQG achieve multichannel output switching, that can switch between single-channel
output, horizontal division 2-channel
output, vertical division 2-channel output,
and horizontal and vertical division 4-channel
output. (See figure 1.)
When 4-channel output is used, these
devices are capable of 25 frame/s output in
progressive scan method, and of 46 frame/s
output in vertical 1092-line cropping mode.
These image sensors can support a wide
range of customer needs by combining these
diverse drive modes with multichannel output
switching.
For example, in vertical 1092-line cropping
mode, a single camera can handle the multiple
lanes that traffic monitoring requires. |
| Both High Sensitivity and High
Resolution |
|
So far diagonal 11 mm (Type 2/3) were the
upper optical limit of Sony lineup of image
sensors for industrial cameras.
The problem with this configuration is that
in attempts to achieve high pixel counts, high
sensitivity, a characteristic valued in security
applications, had to be sacrificed for high
resolution.
However, large optical sensors with a diagonal
15.99 mm (Type 1) provide equivalent or
better sensitivity and high resolution
compared to the current ICX674ALG and
ICX674AQG.
And since they employ the "EXviewHAD
CCD II" structure, they also offer high
sensitivity in the near infrared region. (See figure 2 and table 2.) |
Compatibility with ICX674ALG
and ICX674AQG
|
|
For ease of use, the ICX694ALG and
ICX694AQG have the same package size
as and share the pin configuration of the
ICX674ALG and ICX674AQG, the current
Sony products.
Taking advantage of their high sensitivity
in the near infrared region, they can be used
not only for industrial applications, but as a
black and white high-sensitivity camera for
day and night security camera applications by
removing the IR cut-off filter at night time.
These sensors will be able to meet diverse
customer needs since they can be used in a
wide variety of camera applications. |

In addition to the extensive set of drive
modes that multichannel output switching
permits, the large optical sensors used in
the ICX694ALG and ICX694AQG allowed
us to create a commercial product lineup
that offer both high resolution and high
sensitivity.
Maintaining backward compatibility with
the ICX674ALG and ICX674AQG, the
current Sony products, was one of the
design goals to make the product user
friendly.
Be sure to consider these image sensors
for your next product. |
