Diagonal 6.08 mm (Type 1/3) 1.39M-Effective
IMX035LQR Pixel Color CMOS Sensor for Industrial Applications
Achieves a High Frame Rate and a High S/N Ratio
Sony has now developed the IMX035LQR CMOS sensor for industrial applications, a device that achieves both a
high frame rate and a high signal-to-noise ratio.
The IMX035LQR provides the resolution of a 1.3M-pixel sensor and can produce a maximum frame rate of 120
frame/s (in 10-bit A/D conversion mode). Using pixel technologies fostered in Sony's CCD development work, the
IMX035LQR achieves high signal-to-noise ratio and high sensitivity characteristics that are not available in existing
industrial CMOS sensors.
Sony has also developed a black-and-white version (IMX035LLR) in the same package and a package variant color
product (IMX035LQZ) at the same time.
■ High sensitivity (460 mV typ.)
■ High signal-to-noise ratio (+3 dB
compared to existing Sony products)
■ Extensive set of drive modes
■ Switchable I/O interface
■ Built-in 10 and 12-bit A/D converters

“Exmor” is a version of Sony’s high performance
CMOS 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
possible to image subjects in low light using
a lower gain setting, and even when the gain
is increased, noise is suppressed. As a result,
this device produces high signal-to-noise ratio
video.

Extensive Set of Drive Modes
In addition to the all 1.3M-pixel scan mode,
the IMX035LQR also provides a horizontal
and vertical 2/2-line addition mode, a vertical
1/2 elimination mode, and a window cropping
mode. Furthermore, Sony has newly added
an HD720p mode that supports 720p high-
definition TV readout. Thus the IMX035LQR
provides the functions required to support
a wide range of user needs as a high-speed
CMOS sensor for industrial applications.
that can be switched between 10 and 12-bit
operation so that customers can select the
desired A/D converter bit depth.
IMX035LLR and IMX035LQZ
Sony has developed two other related
products: the IMX035LLR (a black-and-
white device) that includes a black filter
(functions as a mask) and achieves a peak
sensitivity value about twice that of the
IMX035LQR, and the IMX035LQZ (a color
device) that adopts the QFN package for
easier mounting.
All three products are provided in packages
that can withstand high-temperature reflow
soldering (peak temperature: 260°C).
To achieve a high signal-to-noise ratio
in the IMX035LQR, Sony adopted their
unique column-parallel A/D conversion
method*1 in this device. This technology is
highly respected since it aims at reducing
circuit noise and furthermore achieving
high sensitivity even during high-speed
operation using the sensitivity increasing
pixel technologies developed in Sony's work
on CCDs.
Compared to Sony's existing IMX012, the
IMX035LQR achieves a sensitivity 1.5 or
more times higher at an operating frame rate
of 30 frame/s (Ta = 60°C). This makes it
I/O Interface Switching Function
The IMX035LQR adopts a low-voltage
LVDS 1-port DDR output method for small-
signal data output, and thus achieves both
high frame rate readout and low I/O noise
levels. This device's high frame rate readout
mode can acquire video images at up to 120
frame/s (in 10-bit A/D conversion mode) in
all 1.3M-pixel scan mode. The IMX035LQR
also provides a CMOS 1-port SDR output for
the all 1.3M-pixel scan mode at 30 frame/s.
This mode can be selected according to the
application or mounting conditions. Other
features include internal A/D converters
In developing the IMX035, our group
consisted of designers from several
related divisions and it was a pleasure
to proceed with this development while
sharing our various experiences and
specialized areas of expertise. While
there were several issues to be solved,
including signal-to-noise ratio and
sensitivity characteristics under low
ambient light levels and high-speed
operation, we took the time to solve
these one at a time and as a result
created a product that will respond to
our customers' desires. We strongly
recommend that you take a look at the
images produced by this device.
