PR95088
SHANGHAI, Mar. 21, 2022 /PRNewswire=KYODO JBN/ --
According to the latest research by Counterpoint, mobile phones are expected to
account for 71.4% of the total global CMOS image sensor (CIS) market revenue in
2022. Flagship smartphones are chasing DSLR-like shooting performance. Image
sensors as core imaging components have become the key area of focus for
mobile phone camera performance breakthroughs, with 50MP CIS being the most
popular. As the current mainstream configuration for flagship phone main
cameras, the 50MP image sensors are forecast to have a solid life cycle for a
long time in the future.
Recently, SmartSens, an advanced CMOS image sensor supplier, launched its first
50MP ultra-high resolution 1.0ìm pixel size image sensor new product ¯SC550XS.
The new product adopts the advanced 22nm HKMG Stack process as well as
SmartSens' multiple proprietary technologies, including SmartClarity(R)-2
technology, SFCPixel(R) technology and PixGain HDR(R) technology to enable
excellent imaging performance. In addition, it can achieve 100% all pixel all
direction auto focus coverage via AllPix ADAF(R) technology and is equipped
with MIPI C-PHY 3.0Gsps high-speed data transmission interface. The product is
designed to address the requirements of flagship smartphone main camera in
terms of night vision full-color imaging, high dynamic range, and low power
consumption.
Innovative technologies enable premium imaging performance
SC550XS has a 50-megapixel ultra-high resolution with a small pixel size at
just 1.0 µm. Based on the advanced 22nm HKMG Stack process, the sensor combines
SmartSens' unique SFCPixel(R) technology and High Gain in PixGain technology
with 2x2 SmartQCell(TM) micro-lens design to further improve the light
acquisition rate of a single pixel, making it to have superior sensitivity
performance under the same specifications. These technologies, coupled with low
noise reading circuit design and upgraded color process allow the sensor to
present a movie-like image quality in night shooting.
Multiple HDR technologies such as PixGain HDR(R) are supported
The SC550XS integrates SmartSens' innovative PixGain HDR(R) technology through
the combination of High Gain (high conversion gain) and Low Gain (low
conversion gain) dual images under the same frame exposure, achieving
artifact-free motion capture with high-quality HDR imaging. Additionally, the
SC550XS also supports 4K 30fps video in 3-exposure Staggered HDR with up to
120dB and 60fps video in two-exposure Staggered HDR of 100dB. Hence, by means
of the combination of various high dynamic range technologies, the camera can
capture richer detail in the highlights and shadows of a scene.
AllPix ADAF(R) technology provides 100% all pixel all direction auto focus
coverage
Compared with the technology that uses part of the pixels for shooting on the
sensor as phase focus, AllPix ADAF(R) technology utilized on the SC550XS
features full pixel 2x2 SmartQCell(TM) micro-lens design—a combination of
horizontal and vertical pixel binning to reach 100 percent all pixel all
direction auto focus coverage. Therefore, it is capable of offering accurate
and fast autofocus in dark scenes, while optimizing autofocus performance on
objects with blurry outlines.
Better performance comes with lower power consumption
The SC550XS uses an advanced 22nm HKMG Stack process that offers faster device
speed and operates at a lower voltage than the 40nm process employed in the
industry's previous generation of main camera CIS, allowing image sensors to
operate at higher frame rate and lower power consumption. At the same
performance level, the power consumption of the 22nm process can be reduced by
30%. Furthermore, benefited from SmartSens' innovative low power consumption
circuit design, the operating power consumption of SC550XS attains a
significant 43% decrease compared with similar products in this industry,
providing extended battery life for high-end smartphones. 2x2 SmartQCell(TM)
micro-lens design fused with the upgraded pixel process enables the QE (quantum
efficiency) of the SC550XS to reach 82%, resulting in excellent low-light scene
shooting performance.
Additionally, beside similar products in the industry, the SC550XS obtains 20%
increase in FWC, and 20% and 40% reduction in read noise and FPN, respectively,
which further advances the delicate texture of imaging while maintaining
premium low-light performance.
Dr. Yaowu Mo, Co-Founder and Chief Technology Officer at SmartSens said:
"SC550XS is our high-resolution, high-performance milestone product for
flagship mobile phone applications which incorporates several SmartSens core
patented technologies for high-end image sensors including SFCPixel(R)
technology, SmartQCell(TM) micro-lens design, AllPix ADAF(R) technology and
multi-row parallel readout technology, and also takes advantage of advanced
22nm HKMG process, allowing it to support up to 50MP/8K 30fps Bayer RAW high
speed output with excellent dark light results as well as color reproduction
and realize ultra-low power consumption. Multiple hardware-level image
processing and phase focus algorithms are also integrated on-chip, enabling
high quality 50MP/8K/4K video output with high dynamic range and real-time
phase focus.
"In terms of high-speed transmission interface circuit design, we have broken
through the voltage limit under 0.9V power supply, and innovatively achieved
full compatibility with the C-PHY/D-PHY interface protocol to meet the needs of
high-resolution, high-frame-rate video transmission. In addition, as the
current 5G radio frequency interference in mobile phones is becoming more and
more serious, we not only reduce the radiation of the image sensor itself
through spread spectrum technology to obtain better EMI performance, but also
support the C-PHY output swing to be greatly adjustable, further improving its
own anti-interference capability to ensure normal data reception at the module
end.
"We hope that this ingenious work that integrates multiple core technologies of
SmartSens can provide customers with better photo and video results and create
an imaging system with optimized performance."
X represents both the unknown mystery and the infinite possibilities of the
future, as well as the Roman numeral 10. As a landmark product for the tenth
anniversary, SC550XS strives to empower high-end mobile phone camera
applications with advanced product performance. It will start sampling in Q2
2022, and is expected to achieve mass production in Q3 2022. Customized
specification products based on the same process and technology platform are
also welcomed. For more information on SmartSens SC550XS, please contact
