Diagonal 6.4 mm (Type 1/2.8) 2.38M-Effective Pixel Color and
Black-and-White Full HD CMOS Image Sensor for Industrial
Applications Achieves a High Frame Rate and a High S/N Ratio
IMX136LQJ/LLJ
The release of the IMX136LQJ (color) and the IMX136LLJ (black and white) CMOS image sensors brings a high frame
rate, high signal-to-noise ratio and full HD to Sony's CMOS image sensor lineup for industrial applications.
With the same diagonal 2.8 µm square pixels as the IMX122LQJ*1, it maintains the same high signal-to-noise ratio
while capturing HD 1080p video at 120 frame/s.
A versatile interface means that the sensor can be tailored to different applications.
These new ICs are pin compatible with the HD capable IMX104LQJ*2, which simplifies making additions to the lineup.

"Exmor" is a trademark of Sony Corporation.
The "Exmor " is a ver sion 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 Frame Rate and High Signal-to-Noise Ratio Characteristics |
|
As the demand for the high resolution of full
HD grows in the industrial field, there is
an increasing demand for 60p output and
high frame rates for functions that compose
multiple frames.
These new ICs, the IMX136LQJ and the
IMX136LLJ, that Sony are now releasing
deliver 120 frame/s in 10-bit A/D conversion
mode in the HD 1080p format and 60 frame/s
in 12-bit A/D conversion mode.
To ensure both high speed and high signalto-noise ratio, the pixel readout system and circuits have been optimized to give them a
signal-to-noise ratio that equals that of the
IMX122LQJ.

| A Variety of Operating Modes |
|
In addition to the all 2.38M-pixel scan mode
and HD 1080p/720p modes, the IMX136LQJ
and the IMX136LLJ also provide a window
cropping mode.
They also support the multiple frame set
output mode to take better advantage of the
high-speed frame rate. In this mode, separate
exposure time and gain can be set in advance
for 4 or 2 consecutive frames and sets of 4 or
2 frames can be set as a shooting condition
to automatically output consecutive images.
(See photograph 1.)
This mode can generate a picture with a wide
dynamic range as a result of the combination
of multiple frames. |
| Versatile Interface |
|
The output interface has been expanded
to include a high-speed low-voltage LVDS
parallel output in addition to the existing
CMOS parallel output.
For output of HD 1080p at up to 60 frame/s,
a low-voltage LVDS serial 4-channel output
(594 Mbps/channel) is provided.
Also the control interface has been modified
to include a general-purpose I2C interface
besides the existing 4-wire serial interface,
which in combination with the output interface provides customers with options to
suit their operating conditions.
Since these new ICs are pin compatible with
the IMX104LQJ, it is easy to use common
designs. |
| Lineup |
|
This development project adds the
IMX136LQJ, a primary color filter model and
the IMX136LLJ, a black-and-white model, to
the lineup. (See photograph 2.)
The sensitivity of the black-and-white model
(the IMX136LLJ) is 1.5 times greater than that
of the color model (the IMX136LQJ). (See
table 2.) For greater anti-flare characteristics,
the shielding between pixels has been
improved.
And both image sensors are provided in
packages that can withstand high-temperature
reflow soldering (peak temperature: 240°C). |

With its high frame rate and high-speed
features, the IMX136 maintains
the picture quality required of a CMOS
image sensor for industrial applications.
We are convinced the united efforts of
all project members have managed to
develop two new products that will satisfy
customer requirements. Customers are
strongly recommended to take a closer
look at the full HD world that IMX136
makes possible. |
