Overview

OmniVision's front-view OX08A4Y is a high-resolution 8.3MP image sensor with the automotive industry's best HDR of 140 dB. 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 conditions is safety-critical.

The OX08A4Y utilizes OmniVision's dual conversion gain (DCG) technology to achieve 82 dB dynamic 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.

The image sensor has a 1/1.73" optical format with a 2.1-micron pixel pitch. Furthermore, our PureCel®Plus-S stacked architecture enables each pixel to perform optimally via higher full-well capacity for improved HDR. Additionally, the OX08A4Y has region-of-interest functionality for even clearer images of moving objects within fixed areas in the camera's field of view. To ensure the safety of images being used for machine vision applications, ultra low power cybersecurity is also integrated using industry-standard encryption techniques and consuming less than 10% of the sensor's total power budget.

The OX08A4Y offers 4-capture, 3840 x 2160 resolution at 36 fps and a 16:9 display aspect ratio. This image sensor will be available in different color-filter patterns to match the leading machine vision applications in the industry and is planned to be AEC-Q100 Grade 2 certified.
