Smart Eye and STMicroelectronics
demonstrate high-sensitivity,
lower-cost, 1-LED Driver
Monitoring System
- Demonstration, at AutoSens (Sept 12-14) and InCabin (Sept 15)
events in Brussels, highlights power and cost improvements
Geneva, Switzerland,
and Gothenburg, Sweden –
September 13,
2022 – Smart
Eye, a world leader in using artificial intelligence (AI)
to build technology that understands, supports, and predicts human
behavior in complex environments, and STMicroelectronics
(NYSE: STM), a global semiconductor leader serving
customers across the spectrum of electronics applications, today
announced their cooperative development of a high-sensitivity,
1-LED Driver Monitoring System (DMS). Combining Smart Eye’s
expertise in driver monitoring algorithms and optical system design
with ST’s high-sensitivity automotive-grade global-shutter VB56G4A
imager, the new DMS reduces power consumption and system cost by
using only one illumination LED. Current systems typically require
two or more LEDs to adequately illuminate the driver. The
high-sensitivity DMS is demonstrated at this week’s AutoSens and
InCabin exhibitions in Brussels.
“The excellent performance and high sensitivity of ST’s
automotive-grade global-shutter imaging sensor is an excellent
match for Smart Eye’s industry-proven driver-monitoring
algorithms,” said Eric Aussedat, Executive Vice President, Imaging
Sub-Group General Manager, STMicroelectronics. “In developing a
sensor with 2.6µm pixel size and double the quantum efficiency of
previous-generation sensors, we’ve simplified DMS development,
reduced its power consumption, and lowered costs without
compromising performance.”
“Building on our two decades of automotive experience proven by
nearly 100 design wins from leading car manufacturers, we’ve worked
with ST to combine our technology with ST’s advanced image sensor
to eliminate at least half of the expensive LEDs/lenses,” said
Martin Krantz, CEO and Founder of Smart Eye. “Even with this
smaller and more economical design, we’ve created an exceptional
no-compromise DMS demonstrator that shows how automakers can
significantly improve road safety with reduced cost of ownership.
We are happy to support our partners and customers with our HW and
SW reference design and expertise for flawless product
integration.”
The high-sensitivity DMS developed by Smart Eye and ST is being
unveiled and demonstrated at the ST stand (#21) at AutoSens on
September 12-14 at the Autoworld Museum in Brussels and in the same
location at InCabin on September 15. For demonstrations after
AutoSens and InCabin, please contact Smart Eye or ST sales.
Notes to
EditorsThe VG56G4A, announced earlier this year, is ST’s
second generation automotive-grade global-shutter sensor for driver
monitoring systems. This sensor leverages ST’s in-house investment
in manufacturing advanced 3D-stacked back-side illuminated (BSI-3D)
image sensors. These sensors are more sensitive, smaller, and more
reliable than the conventional front-side illuminated (FSI) sensors
typically being used in first-generation DMSs.
The sensor achieves high Quantum Efficiency (QE), reaching 24%
at 940nm near-infrared (NIR) wavelength, with linear dynamic range
up to 60dB. This enables a simple low-power, non-visible LED
emitter to provide adequate illumination for the sensor. Operating
outside the visible spectrum also ensures consistent response in
day or night driving and in bright or overcast conditions, while
minimizing potential driver-fatigue issues.
In addition to the sensor’s high QE, it implements a
global-shutter approach that offers big advantages over
rolling-shutter imagers. The global shutter simultaneously exposes
all pixels to the scene, allowing simple synchronization with NIR
illumination. This lowers the illumination-subsystem power budget.
Combining a pixel size of just 2.6µm with the high QE and global
shutter helps optimize total power consumption and camera size. In
addition, integrated automatic exposure control eases use and
simplifies the application-software design by minimizing system
interaction with the sensor.
The sensor also provides flexible operating modes that help
optimize system features and performance. These include
programmable sequences of 4-frame contexts, illumination control
outputs synchronized with sensor integration periods, and an input
for an external frame-start signal. Additional features include
automatic dark calibration, dynamic defective-pixel correction,
image cropping, and a mirror/flip-image readout.
External connections include eight programmable general-purpose
I/O (GPIO) pins and a dual-lane MIPI CSI-2 transmitter interface
operating up to 1.5 Gbps per lane. The sensor can operate at up to
88 frames per second (fps) at full resolution and typical power
consumption is 145mW at 60 fps.
