With an innovation that could inject new life into the global
digital-camera market, CEA-Leti will demonstrate its new technology for
image sensors at CES 2019 that replicates the curve of the human retina.
This curved image sensor technology breakthrough, called Pixcurve,
requires fewer lens elements in digital cameras, which shrinks camera
size by half and lowers costs – while improving image quality.
“The digital camera market has taken a huge hit from the massive
adoption of smartphones, even though these bigger cameras deliver better
image quality than smartphone cameras,” said David Henry, manager of
packaging and assembling at CEA-Leti. “Pixcurve, which also reduces
camera sizes in smartphones, microdisplays and virtual-reality glasses,
provides camera manufacturers with cost effective, compact,
easy-to-assemble optical components they need to bring their products to
new levels of performance in the digital era.”
Portability is a big factor for many consumers, and smaller, lighter and
less-expensive digital cameras will enable camera makers to increase
their share of the global market. With Pixcurve, CEA-Leti, a French
research institute, has developed an innovative solution for the visible
imaging market and beyond.
Form FactorReducing the number of lens elements in digital
cameras from 10 to six reduces the size of the final compound lens by 60
percent. The overall length of the optical system also is shorter.
Improved PerformanceCurved image sensors reduce—and in some
cases completely eliminate—optical aberrations like curvature of field
and the vignetting effect. They also deliver increased brightness and a
wider field of view.
CostReducing the number of lens elements and eliminating
aspheric lens elements, which will be unnecessary, will lower the cost
of systems integrating Pixcurve technology.
AssemblyFewer components means quicker and easier
assembly—a major advantage for manufacturers.
CEA will host a ‘CEA Tech Village’ at booth 51253 in Eureka ParkVisitors
at the Pixcurve booth at CES will see before-and-after examples on two
tablets, illustrating the substantial size reduction that Pixcurve
curved-sensor technology can bring and proving that there is no decline
in image quality.
Pixcurve also will be featured at CES Unveiled.
