Omnivision has revealed the 1/2″ camera sensor named as OV6B for smartphones. According to the company, it is the world’s first 0.7-micron 64-megapixel image sensor. This sensor is aimed at high-end smartphones.
The company made use of PureCel Plus-S stacked die technology, developed in-house to manufacture the Omnivision OV64B. They also employed four-cell colour filter array or CFA with on-chip hardware for re-mosaic. Thanks to the pixel -binning technology that combines adjacent pixels into 1, the sensor output 16-megapixel size images natively.
This helps reduce the image size without compromising on quality. In 16-megapixel size, the images posses 4x sensitivity from the near-pixel binning making the results comparable with those from 1.4-micron pixel size, says the company. What it ultimately aims to achieve is better low-light photography. In the video front, OV64B supports 4K resolution with Electronic Image Stabilisation (EIS). The maximum output it can produce is 8K resolution, albeit at 30 frames per second (FPS). The slo-mo capabilities are matched with 240 FPS at 1080P or 480 FPS at 720P.
The Omnivision OV64B features type-2, 2×2 microlens Phase Detection AutoFocus (ML-PDAF). This technology helps boost autofocus accuracy. Additionally, it has a CPHY interface that helps produce better throughput with lesser pins.
This sensor competes with Sony’s IMX686 64-megapixel camera sensor. In comparison, the offer from Sony is of size 1/7″ and has a pixel size of 0.8-micron. Another sensor from Sony which was used in last year’s flagship was the IMX586 48-megapixel sensor. It is a 1/2-type sensor and has a pixel size of 0.8 microns.
According to the company, the first batch of sensors will start shipping to interested smartphone makers in May. As of now, it is unclear about the details of the companies planning to use the new camera sensor.
