announced the S5K4EA, a new quarter-inch optical format, 5-megapixel system-on-chip
(SoC) image sensor that will bring high quality digital still camera
functionality to high-end mobile phones. This imager combines a CMOS image
sensor with an image signal processor to give mobile handset designers a cost
effective and size efficient solution.
The S5K4EA SoC imager offers adaptive dynamic range
expansion capabilities to help brighten shadowed areas of a picture and
intensify brighter regions. The imager also has an anti-shake control feature
and the ability to process 1080p resolution images at 30 frames-per-second for
high quality video capture.
Although it will be a little while before you and I see the
benefits of this new imager in our phones, mass production of the imager is slated
for the first quarter of 2010.
5-Megapixel SoC Image Sensor Brings Digital Still Camera
High-end Mobile Phones
)--Samsung Electronics Co., Ltd., a world leader in advanced
semiconductor solutions, announced its newest quarter-inch optical format,
5-megapixel (Mp) system-on-chip (SoC) image sensor, the S5K4EA, which brings
digital still camera functionality to high-end mobile phones. The chip was revealed
at the sixth annual Samsung Mobile Solutions Forum held at the Westin Taipei
Hotel. Targeted at smart phones and advanced handsets, the S5K4EA SoC imager
combines a CMOS image sensor with an image signal processor, giving mobile
handset designers a cost effective and size efficient solution.
“Mobile phones today allow us to stay in contact with
friends and family not only by voice and text but also with high resolution
images,” said Dr. Lee Yun Tae, senior vice president, image development team,
System LSI Division, Samsung Electronics. “To meet the current demand for
slimmer, sleeker mobile phones with digital still camera capabilities, Samsung
brings 1.4-micron (um) pixel technology to this state-of-the-art imager
Samsung’s S5K4EA imager has regionally adaptive dynamic
range expansion to brighten shadowed areas of a picture and intensify the
clarity of brighter regions. In addition, its fast frame capture with
anti-shaking control feature enables sharp pictures by reducing blur caused by
jitter from unsteady hands. Capable of processing 1080p resolution images at 30
frames-per-second, the S5K4EA supports high quality video capture on advanced
To meet the current trend of ever smaller mobile devices
with HD capabilities, Samsung’s advanced pixel shrink technology was utilized
to achieve a tiny, ultra-sensitive 1.4um pixel size. Samsung’s proprietary
pixel technology, the Samsung Enhanced Energy Steering (SEES), integrates more
light into an optimized pixel structure to present clear, high resolution
images. Advanced noise removal logic is also used to further improve image
Samsung’s S5K4EA also offers auto focus, Xenon flash,
mechanical or electronic rolling shutter. For designers, this new imager has a
YUV output interface over MIPI2 or parallel. It also has JPEG with thumbnail
output to speed up picture browsing on the phone.
The S5K4EA imager is available in an auto focus 8.5x8.5x6mm
or smaller module. Samples are currently available with mass production slated
for the first quarter of 2010.
According to market research firm, Techno Systems Research,
camera phones are forecast to rise from 750 million units sold in 2009 to 1.23
billion units in 2013. The sales volume of 5Mp and higher high resolution
camera phones is expected to reach 98 million units in 2009 and grow to 660
million units in 2013, at a compound annual growth rate of 61 percent.
