STMicroelectronics sets the scene for
advanced in-car safety and comfort with new hybrid sensor for full
interior monitoring
- Hybrid rolling and global-shutter image sensor extends basic
driver monitoring to enable more adaptive and convenient vehicles
for all occupants
- Driver monitoring market is growing at more than 10% per
year
Geneva, September
8,
2022 –
As leading automotive markets start to mandate driver-monitoring
systems (DMS), STMicroelectronics (NYSE: STM), a
global semiconductor leader serving customers across the spectrum
of electronics applications, is already equipping carmakers with
the required technologies. While DMS promises greater road safety
by assessing driver alertness, the next-generation dual image
sensor ST announced today monitors the full vehicle interior
covering both the driver and all passengers. New applications
enabled by ST’s new image sensor include passenger safety-belt
checks, vital-sign monitoring, child-left detection, gesture
recognition, and high-quality video/picture recording.
“The DMS market is growing at a double-digit pace. ST’s new
image sensor is set to push that forward by enabling brands to
create new services and deliver even greater value for vehicle
users, leveraging complete in-cabin monitoring that covers multiple
occupants,” said Eric Aussedat, Executive Vice President, Imaging
Sub-Group General Manager, STMicroelectronics. “Our market-leading
DMS sensor provided the perfect launchpad to take the technology
further and empower new innovations.”
The new sensor, the VD/VB1940, delivers a cost-effective
solution that combines the sensitivity and high resolution of
infrared sensing with high dynamic range (HDR) color imaging in a
single component. It can capture frames alternatively in
rolling-shutter and global-shutter modes. With 5.1-megapixels, it
captures the high-dynamic-range (HDR) color images needed for an
occupant monitoring system (OMS) in addition to the high-quality
near-infrared (NIR) images typically captured by standard DMS
sensors. DMS uses NIR imaging to analyze driver head and eye
movements in all lighting conditions.
Offered in both bare wafers (VDB1940) and packaged in BGAs
(VB1940), samples are available now and mass production is planned
to meet demand for the model-year 2024 vehicles being designed now.

Further Technical Information
The new automotive image sensor uses ST’s second-generation
3D-stacked back-side illuminated (BSI) wafer technology, which
maximizes the optical area and on-chip processing in relation to
die size. This lets the sensor perform sophisticated algorithms
locally for optimal performance in both color and NIR imaging,
saving power and relieving demand for an external co-processor.
Algorithms performed on-chip include Bayer conversion and HDR
merging for optimal image-quality and frame rate. On-chip
Bayerization processing enables the user to reshuffle the color
pixels of the RGB NIR 4X4 pattern into RGGB format compatible with
a wide range of SoCs. In addition, local processing also handles
independent color and NIR pixel-exposure optimization for optimum
image quality in both modes, as well as smart upscaling to maximize
NIR image resolution by capturing extra NIR information from RGB
pixels.
The embedded processor also manages enhanced cybersecurity to
ensure privacy in connected-vehicle applications, including mutual
authentication and pairing of camera and electronic control unit
(ECU), as well as video-stream authentication.
The sensor captures NIR images in global-shutter mode, which
permits synchronizing with the infrared LED emitter to capture
fast-moving scenes without motion blur. By also supporting
rolling-shutter mode, which reads pixel data row by row, the
VD/VB1940 provides optimum color-imaging performance. Leveraging
the on-chip HDR-merge feature in rolling-shutter mode, the
VB/VD1940 produces a 100dB full-resolution color image.
Qualified to AEC-Q100, the VD/VB1940 is ISO 26262 compliant to
facilitate use in functional-safety systems up to ASIL-B.
