CES2020: 4K image sensor offers HDR for mobile phones
The company has announced the OV48C 48 megapixel image sensor at the Consumer Electronics Show in Las Vegas. It comes just six months after the launch of the OV48B (see Sensor with 48Mpixels sets sights on smartphones) which had a smaller pixel size and did not boast of HDR.
The OV48C provides on-chip dual conversion gain HDR and offers a staggered HDR option with on-chip combination, allowing smartphone designers to select the HDR method for a given scene.
The sensor is made using OmniVision’s PureCel Plus stacked-die technology and comes in a 1inch by 1.3inch format. The OV48C also integrates an on-chip, 4-cell color filter array and hardware remosaic, which provides high quality, 48MP Bayer output, or 8K video, in real time. In low light conditions, this sensor can use near-pixel binning to output a 12MP image for 4K2K video with four times the sensitivity, yielding a 2.4 micron-equivalent performance. In either case, the OV48C can consistently capture the best quality images without motion blur, as well as enabling digital crop zoom with 12MP resolution and fast mode switch. Additionally, this sensor offers a wide range of features, including digital crop zoom and a CPHY interface, making it ideal for main, rear-facing cameras in multicamera configurations. The OV48C also uses 4C Half Shield phase detection for fast autofocus support.
Output formats include 48MP at 15 frames per second (fps), 12MP with 4-cell binning at 60 fps, and 4K2K video at 60 fps with the extra pixels needed for electronic image stabilization. This sensor also offers 1080p video with slow motion support at 240 fps, as well as 720p at 360 fps.
