Diagonal 6.4 mm (Type 1/2.8) 2.43M-Effective Pixel HD1080 p CMOS
Image Sensor for Industrial Applications Achieves High Picture Quality
under Low Illumination Due to High Sensitivity and High S/N Ratio
IMX122LQJ
In recent years, there is an increasing demand for HD1080 p capability in CMOS image sensors for industrial applications.
Sony has released the IMX122LQJ, a CMOS image sensor (Type 1/3 optical size) that provides HD1080 p high picture quality
video output under low illumination thanks to high sensitivity and high signal-to-noise ratio.
The sensor features an improved pixel technology using diagonal 2.8 µm square pixels, which has improved the signal-to-noise
ratio by +8 dB over the current Sony products.
The compact and low profile package contributes to space saving when mounting.

The "Exmor " is a version of Sony 's high
performance CMOS image sensor with high-speed
processing, low noise and low power dissipation by
using column-parallel A/D conversion.
High Sensitivity and Signal-to-Noise Ratio Characteristics
In the release of the IMX122LQJ CMOS
image sensor, Sony has created a Type 1/3
highly sensitive CMOS image sensor that
supports high speed operation of HD1080 p
at 30 frame/s for industrial applications. The
IMX122LQJ employs diagonal 2.8 µm square
pixel whose light collecting efficiency has
been improved by better process technology
while optimum pixel design has provided
it with high picture quality due to high
sensitivity and low noise.
In addition, it incorporates internal high-speed
processing and circuit technology to counteract fixed pattern noise to enable HD1080 p at 30 frame/s even in peripheral circuits. As a result, it delivers sensitivity
characteristics of +6 dB and an signal-to-noise
ratio of +8 dB when compared to our
current Type 1/3 HD1080 p sensor. Our
customers especially appreciate new product
high sensitivity under low illumination and
high picture quality due to its low noise .
This sensor also reduces random noise and
fixed pattern noise at high temperatures.
HD1080 p Operation Mode
The demand for HD1080 p in industrial
cameras is growing now and the demand for
CMOS image sensors capable of 30 frame/s
output in HD1080 p is equally strong.
Sony has now developed the IMX122LQJ
image sensor, which achieve HD1080 p
output at 30 frame/s with 10-bit/12-bit A/D
conversion. And WUXGA (Wide Ultra
Extended Graphics Array) resolution is
adopted in an all-pixel scan mode to support
UXGA (Ultra Extended Graphics Array)
resolution at a 4:3 aspect ratio.
Furthermore, this sensor has other various
functions for industrial applications, such as
HD720 p mode or window cropping mode
provide functions for changing the output
pixel area.
Parallel/Serial Interface
The IMX122LQJ has two output interfaces, a CMOS parallel output (max. 74.25M pixels/s)
that is designed for flexible use to connect
DSP and high-speed LVDS serial output
(max. 648 Mbps/port), 1 port or 2 ports,
that can be selected according to their usage
conditions.
Compact and Low-Profile Package
The IMX122LQJ is integrated in a compact
and low-profile LGA package (98-pin LGA)
to meet the need for compact sensors in low-profile
and compact devices.
This has reduced the chip size package by
about 30% compared to the current Sony
products and makes possible the design of
compact devices. And its high temperature
reflow (peak temperature: 240°C) characteristics
facilitates mounting.
•••• Mr. Kudo••••
In the development of the IMX122LQJ,
our development team members
worked together to create a product
with both high sensitivity and low-noise
characteristics.
The sensor enables shooting in low
ambient lighting conditions where objects
are invisible to the human eye, so we
succeeded in our goal of creating a
sensor that could exceed the human eye
despite the small 2.8 µm square pixel
size that it employs.
I strongly recommend that you look into
this image sensor with its high picture
quality in your next product.
