OMNIVISION announces new solutions for automotive OX05B: 5MP RGB-IR Global Shutter Sensor for In-Cabin Monitoring Systems
The new OX05B1S is the 5 megapixel (MP) RGB-IR BSI global shutter sensor for in-cabin driver monitoring systems (DMS). With a pixel size of just 2.2 µm, it offers 940 nm NIR sensitivity for the best performance in extremely low light conditions; it has a wide field of view and enough pixels to view both the driver and occupants. Additionally, it is the first RGB-IR sensor for in-cabin monitoring to feature integrated cybersecurity. Based on OMNIVISION’s revolutionary Nyxel® NIR technology, the new OX05B1S brings dramati-cally improved resolution as well as overall enhanced efficiency and design flexibility to automotive OEMs. Nyxel® technology uses novel silicon semiconductor architectures and processes to achieve the world’s best quantum efficiency (QE) at the 940 nm NIR wavelength. The OX05B1S has the industry’s highest NIR QE at 35% (a 4x boost from 12% in the previous generation). This enables the OX05B1S to detect and recognize objects that other image sensors would miss under extremely low lighting conditions, enabling higherperformance incabin camera capabilities for improved occupant and driver monitoring, security, selfies, videoconferencing and more. OX03D: 3MP Resolution SoC for Automotive Cameras OMNIVISION’s new OX03D4C is a 3 megapixel (MP) resolution systemonchip (SoC) for automotive surround-view systems (SVS), rearview systems (RVS) and e-mirrors. The new SoC provides a seamless path for automotive OEMs to upgrade from 1MP to 3MP while retaining high perfor-mance, low power and the smallest 2.1 µm pixel size in a 1/4-inch optical format. The OX03D4C has a fully integrated image signal processor (ISP), is capable of 140 dB high dynamic range (HDR), and includes the next-generation tone-mapping algorithm along with the LED flicker mit-igation (LFM) performance in the industry. OMNIVISION’s OX03D4C includes both the pixel array and ISP within a single package; it is opti-mized to deliver ideal performance over the complete automotive temperature range. It fea-tures 105 dB motion-free HDR with a total range of 140 dB, and provides HDR and LFM simulta-neously. It includes the next-generation tone-mapping algorithm for high contrast images, sup-ports a number of CFA patterns, and can output both YUV and RAW process streams at the same time. The OX03D4C provides four on-screen display overlay layers for driver guidelines, as well as distortion correction to straighten any curved edges from lenses with a wide viewing angle. The OX03D4C consumes less than 500 mW power, enabling the use of a plastic case for lighter weight and lower cost. All of these features are built into the smallest possible camera module available for automo-tive viewing applications. The a-CSP™ package size allows smaller cameras that can fit in much tighter spaces. The image sensor is built on OMNIVISION’s PureCel®PlusS stacked die technology. OX08B40: 8-Megapixel LFM Image Sensor System for Forward Looking Automotive Camera Systems OMNIVISION’s OX08B40 is a front-view, 8.3MP image sensor that features the automotive indus-try’s best HDR of 140 dB and adds a new benchmark in LED flicker mitigation (LFM) perfor-mance, enabled by the sensor’s on-chip HALE (HDR and LFM engine) combination algorithm. The optimal clarity and range offered by this sensor, in combination with integrated ASIL-C features, is vital for front-view automotive applications, such as ADAS and level 3+ autonomous vehicles, where the ability to accurately detect people and objects from far away in all lighting condi-tions is safety-critical. The OX08B40 utilizes OMNIVISION’s dual conversion gain (DCG) technology to achieve 82 dB dy-namic range on the first exposure, whereas competitors’ image sensors only provide a dynamic range of 60 dB or less. Unlike DCG, the competing method, known as staggered HDR, relies on additional passes that introduce motion artifacts and diminish range, especially in low light. Ad-ditionally, our 3D stacking technology allowed us to integrate our unique HALE combination algorithm into the OX08B40. The OX08B40 offers 4-capture, 3840 x 2160 resolution at 36 fps and a 16:9 display aspect ratio. It will be available in different color-filter
