Advanced Sensor Technology Marks Evolution in Pixel Structure
SANTA CLARA, Calif., — November 8, 2015 — OMNIVISION Technologies, Inc. (Nasdaq: OVTI), a leading developer of advanced digital imaging solutions, today announced the latest advancement in its portfolio of innovative pixel technologies: PureCel®Plus and PureCel®Plus-S. Utilizing a buried color filter array (BCFA) and deep trench isolation (DTI) technology, PureCel®Plus and PureCel®Plus-S sensors deliver best-in-class pixel performance with significant improvements in low-light performance and crosstalk reduction.
One of the key benefits of PureCel®Plus technology is the reduction of pixel crosstalk, which minimizes color crosstalk and color noise, dramatically improving color reproduction under low-light conditions. Another critical benefit is the angular response of the sensor. With PureCel®Plus technology, OMNIVISION’s sensors can provide higher signal response at a larger incident light angle than the one with predecessor technologies. This technology greatly increases the tolerance of new camera systems to incident light angles. As a result, with PureCel®Plus sensors, module design houses can use brighter lenses and build camera systems with much thinner geometries.
“It has long been an industry-wide presumption that increasing resolution by reducing pixel size may result in the degradation of camera performance, due to low-light sensitivity. However, as we are seeing with PureCel®Plus, that is not always the case,” said Dr. Song Xue, senior manager of sensor technology at OMNIVISION. “Our new 1.0 micron sensors built on PureCel®Plus technology will exhibit the same level of signal-to-noise ratio as 1.12 micron sensors built on our previous generation technologies. Today’s advancement enables us to continue reducing pixel size while maintaining the highest image and video quality standards.”
In addition to PureCel®Plus, PureCel®Plus-S leverages OMNIVISION’s stacked die technology, which separates the imaging sensor array from the image sensor processing pipeline. This configuration supports additional system functionality and improves sensor performance, while enabling a much smaller footprint when compared with non-stacked sensors. As a result, sensors built with PureCel®Plus-S technology can deliver best-in-class image quality and high functionality with minimal chip size.
