High-Sensitivity, High-Resolution Camera Systems for
Security Cameras Based on Diagonal 6.0 mm (Type 1/3)
480K/570K-Effective Pixel Color CCD Image Sensors
CXD4127GG,CXD4816GG
ICX672AKA/ICX673AKA
In June 2009, Sony released the "Effio" System (CXD4112GG + CXD4813GG), which achieves the high sensitivity and high
resolution considered critical in security cameras market.
This article introduces the "Effio-E" System (CXD4127GG + CXD4816GG), which is an entry-level model of the "Effio" Series.
By combining this system with the ICX672AKA/ICX673AKA newly-developed CCD image sensors, users can take the lead in the
security camera market, which now requires high sensitivity and high resolution.

"Effio-E" System
CXD4127GG, CXD4816GG
■ Extensive functionality and high
picture quality
■ Built-in OSD functions
"Effio" is a trademark of Sony Corporation. The"Effio" is a signal processor chip from Sony
employing processing modes that deliver high
resolution, high S/N ratio and excellent color
reproduction.
"EXview HAD CCD II"
ICX672AKA/ICX673AKA
■ Horizontal (effective) resolution: 960
pixels (960H CCD image sensor)
■ High sensitivity and high saturation
signal
"EXview HAD CCD II" is a trademark of Sony
Corporation. "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".

 "Effio-E" System
CXD4127GG, CXD4816GG |
|
The "Effio-E" System is an entry-level model
camera system that is designed for easy
introduction into end products from design
through mass production and that inherits
the basic picture quality characteristics that are features of the "Effio" Series, that is,
high sensitivity, high resolution, and excellent
color reproduction. The "Effio-E" System
has a simple, 2-chip structure consisting of
an analog IC (AFE: CXD4816GG) and a
signal-processing IC (DSP: CXD4127GG)
and supports a wide range of CCD image
sensors, including 510H, 760H, and 960H
CCD image sensors. (See figure 1.) These
devices are provided in compact LFBGA
packages and, due to the adoption of a new
process technology generation, achieve a
power consumption of 1/2 that of current
systems. Thus the "Effio-E" System can
contribute to miniaturization and reduced
power consumption in camera products. |
| Extensive Functionality and
High Picture Quality |
|
Even though the "Effio-E" System is an entry-level
model camera system, it includes not
only a noise reduction function, but it also
provides an ATR (adaptive tone reproduction)
function (photograph 1) that improves contrast
in bright/dark areas and a HLC (highlight
compensation) function that suppresses strong
headlights at night and improves visibility
to provide clear images with superb picture
quality.
In addition to the existing static method for
white pixel detection and compensation, it
also includes for the first time a dynamic
method that can handle secondary white
pixels. Furthermore, when combined with the
ICX672AKA/ICX673AKA 960H CCD image
sensors, it can provide the high horizontal
resolution of 650 TV lines or higher. (See
table 1.) |
Built-in OSD Functions
|
|
The "Effio-E" System includes OSD
(on-screen display) functions that allow
camera settings to be made using the display.
This function provides preset menus in eight
languages (English, French, German, Spanish,
Portuguese, Chinese, Russian, and Japanese)
and allows camera settings to be made easily
without using an external microcontroller. |
"EXview HAD CCD II"
ICX672AKA/ICX673AKA
|
|
The newly-developed ICX672AKA/ICX673AKA 960H CCD image sensors
are "EXview HAD CCD II" devices. The
"EXview HAD CCD II" technology is a
further evolved version of the "EXview HAD
CCD" in which "Super HAD CCD II"*1
technology has been incorporated.
Compared to the current ICX638BKA/ICX639BKA, these new devices increase
the number of horizontal pixels and achieve
a high saturation signal level and high
sensitivity that extends into the near infrared.

Under the name Create 960H World with
"Effio" System, Sony now provides the
new standard solution for the security
camera market with the combination of a
960H CCD image sensor (960 pixels in
the horizontal direction) and the "Effio"
family devices. I strongly recommend that
you look into this new world of security
cameras. |
