Johannes Solhusvik

GM at OmniVision


Johannes Solhusvik received the B.Eng. in EEE from Univ of Strathclyde, Glasgow, U.K., in 1989. He then joined the Norwegian Defence Research Establishment, Kjeller, working on IR and CCD image sensors. He moved to France in 1992 to pursue a Ph.D. on low-noise CCD readout and CMOS image sensor design at Ecole Nationale Supérieure de l’Aéronautique et de l’Espace (SUP’AERO), Toulouse. After graduation in 1996, he joined ABB, Norway, where he worked on robotics, telecommunication and CMOS imaging. In 1999, Dr. Solhusvik established Photobit’s European design center in Oslo, Norway, chartered to design custom CMOS Active Pixel Sensors for various applications. In parallel, Dr. Solhusvik also served as assistant adjunct professor at NTNU, Trondheim, teaching CMOS image sensor design. He managed Photobit (Norway) through the Micron acquisition in 2001 and expatriated in 2004 to Micron’s sensor design headquarter in Pasadena, CA, as Director of image sensor design with teams in USA as well as in Japan, UK and Norway. After two years he repatriated back to Micron (Norway) to focus on CIS R&D, in particular HDR and Global Shutter sensors. In 2009 he was part of the Aptina spin-off from Micron. Dr Solhusvik was in 2011 promoted to BU-CTO of Aptina’s Automotive and Industrial Business Unit. In March 2012 he joined Omnivision Technologies as General Manager for Europe Design Center located in Norway. Dr. Solhusvik has served as TPC member of the IEEE ISSCC and is now serving for ESSCIRC. In June 2009 he was TP Chair at IISW held in Norway ( He organized and chair’ed the Imaging Forum at ISSCC, SF, in 2010 and 2011, and was guest organizer of the 2012 and 2013 Imaging Forum. Dr. Solhusvik is member of the Board of Directors of the International Image Sensor Society, Inc. (former ImageSensors, Inc). Since 2013 he has a 10% position as assistant adjunct professor at Univ Oslo teaching CMOS image sensor design.


CMOS image sensor technologies for high dynamic range capture

Regular consumer grade CMOS image sensors (CIS) typically output 8-12 bit pixel values with a dynamic range around 40-70dB. High dynamic range (HDR) imagers typically offer 120dB or sometimes higher. This is used to avoid saturation, and to maintain correct color, in bright areas of the scene whilst at the same time maintaining high sensitivity in the dark part of the scene. Many HDR techniques have been published over the last three decades. Most of them generate image artifacts in cases of fast moving objects in the scene and/or flickering light sources. Following a brief introduction about OmniVision the presentation will describe novel HDR capture methods and solutions used to better cope with fast motion and non-stable lighting.
