OmniVision Defines Mobile Imaging Technology
OmniVision’sportfolio of high-performance CMOS image sensors has been driving innovation in digital imaging for more than two decades. With each new generation of pixel technology, OmniVision strives to exceed manufacturer and end-user expectations by developing compact and power-efficient imaging solutions that capture stunning images and video for every product segment.
Its new family of high-performance PureCel™ image sensors was designed specifically with mobile applications in mind, offering best-in-class pixel performance to capture extraordinarily detailed images and video, even in challenging lighting conditions. PureCel™ image sensors also offer significantly reduced power consumption, standing as the most power-efficient products on the market for the mobile segment.
OmniVision is a leading provider of CMOS image sensors to mobile device markets, with well over 5 billion sensors shipped. The company has maintained a solid track record of supplying some of the world’s largest handset manufacturers with innovative, high-performance and cost-effective digital imaging solutions. The company’s understanding of the fast-evolving mobile device markets, combined with its world-class products and expertise, enables its customers to stay at the leading edge of digital imaging trends for mobile devices.
Continuously ranking among the world’s top three suppliers of image sensors to the mobile phone market, OmniVision has constantly stayed ahead of the industry curve, establishing a leading position by commercializing the industry’s first backside illuminated pixel technology products with its OmniBSI™ pixel architecture, and building on it to offer OmniBSI+™ and OmniBSI-2™ next-generation BSI technologies, with OmniBSI-2™ making OmniVision the first company in the world to create a 1.1-micron pixel. Its new brand of PureCel™ image sensors are built on the company’s most advanced process nodes and add to its broad portfolio of backside illumination technologies, with innovative image sensor design to offer best-in-class pixel performance and power consumption products for the mobile market.
OmniVision Offers the Industry’s Widest Product Portfolio
As the global camera phone market has grown to more than 1.5 billion units a year, it has also become widely segmented, ranging from high-end smartphones, which deliver exceptional images and video with both front- and rear-facing cameras, to feature phones offering more cost-effective low-resolution cameras and smaller form factors. To be a complete supplier, OmniVision offers an extensive portfolio of CMOS image sensors dedicated for mobile consumer products spanning VGA to 16-megapixels in a wide range of optical formats.
OmniVision’s Industry-Leading Mobile Imaging Technologies
OmniVision’s technology leadership is the main driver behind the company’s strong market position. OmniVision is focused on meeting its customers’ demands through continuous investment in advancing CMOS image sensor performance and imaging systems. Currently, OmniVision offers several pixel platforms ideally suited for a wide range of personal computing devices with imaging applications including feature phones, smartphones and tablets.
As OmniVision’s first backside illumination pixel architecture, OmniBSI™ represented a shift in the evolution of digital imaging technologies. OmniBSI allowed OmniVision to further shrink pixels without sacrificing performance, enabling higher resolutions and more compact designs. OmniBSI™ demonstrated a 50 percent increase in sensitivity and quantum efficiency relative to frontside illumination technologies. OmniVision’s introduction of OmniBSI™ products and their superiority to existing frontside illumination technologies made backside illumination a “must-have” for OEMs in the mobile market.
OmniBSI-2™ is OmniVision’s second-generation backside illumination pixel architecture, and the first built on 300 mm wafers using a copper process with 65 nm design rules. The process and design rules enable a number of substantial improvements compared with the company’s original OmniBSI™ technology, including improved pixel layout, better isolation, significantly reduced crosstalk, lower power consumption and faster frame readout.
Focused on the end-user’s experience, OmniVision’s newest PureCel™ image sensors offer an unparalleled performance-to-power-consumption ratio. PureCel™ image sensors by OmniVision use innovative proprietary packaging and pixel technology to deliver industry-leading photon conversion, full-well capacity and light sensitivity, while significantly reducing power consumption. The result is enhanced image color reproduction in both high- and low-light conditions for both still photography and videography.
OmniVision still offers frontside illuminated OmniPixel3-HS™ technology-based CMOS image sensors for the mobile market, for lower resolution products with larger pixels, to offer cost-effective products with excellent sensitivity.
OmniVision Offers Multiple Package Options
The majority of OmniVision’s sensors are offered as COB/RW (bare die options) or in CSP packaging, pioneered by OmniVision to simplify module manufacturing and remove blemishes from particles on the sensor pixel array. CSP, now a well-established packaging technology in the CMOS image sensor market, has the same area as a bare die, and is a surface-mount device, so that the sensor can be soldered directly onto a printed circuit board.
