2000 ipo 2002 first mobile handset camera accessory 2004 first 1.3 megapixel and 2 megapixel sensors for mobile phones 2005 acquired cdm optics a company founded to commercialize wavefront coding . 3 2006 introduced the world s smallest nts camera 2007 launched first automotive hdr soc sensor 2008 launched omnibsi architecture 2011 acquired kodak patents 4 2013 launched purecel cmos image sensors 2015 signed an agreement to be acquired by a group of chinese investors including hua capital management citic capital holdings and goldstone investment for about 1.9 billion in cash in april 2015 . 5 technologies edit an ov7910 and three ov6920 image sensors both types with composite video outputs . omnipixel3 hs edit omnivision s front side illumination fsi technology architecture enhances image capture under very low lighting conditions . it is used to manufacture compact cameras in mobile handsets notebook computers and other applications that require low light performance without the need for flash . omnipixel3 hs is the technology behind its image sensor module that will for example be used by dahua a video surveillances provider to produce cloud based cameras for smart home systems . 6 omnibsi edit backside illuminated image bsi technology differs from fsi architectures in how light is delivered to the photosensitive area of the sensor . in fsi architectures the light must first pass through transistors dieletric layers and metal circuitry . in contrast omnibsi technology turns the image sensor upside down and applies color filters and micro lenses to the backside of the pixels resulting in light collection through the backside of the sensor . this puts the metal and dielectric layers below the sensor array providing the most direct path for light to travel into the pixel which optimizes image quality . omnibsi 2 edit the second generation bsi technology developed in cooperation with taiwan semiconductor manufacturing company limited tsmc is built using custom 65 nm design rules and 300mm copper processes . this combination supports improved low light sensitivity dark current and full well capacity over the first generation of bsi technology as well as sharper image quality . cameracubechip edit in this camera module sensor and lens manufacturing processes are combined using semiconductor stacking methodology . wafer level optical elements are fabricated in a single step by combining cmos image sensors chip scale packaging processes csp and wafer level optics wlo . these fully integrated chip products have camera functionality and are intended to produce thin compact devices with advanced imaging capability . purecel edit omnivision developed its purecel image sensor technology to provide added camera functionality to smartphones and action cameras . the technical goal was to provide smaller camera modules that enable larger optical formats and offer improved image quality especially in low light conditions . 7 both of these technologies are offered in a stacked die format purecel s and purecelplus s . this stacked die methodology separates the imaging array from the image sensor processing pipeline into a stacked die structure allowing for additional functionality to be implemented on the sensor while providing for much smaller die sizes compared to non stacked sensors . when compared with other bsi image sensor technologies purecel technology has demonstrated reduced pixel cross talk minimized color crosstalk and color noise and improved color reproduction under low light conditions . 8 references edit corporate fact sheet pdf .
