OmniVision has developed the first 0.9-micron pixel sensors. The combination of smaller pixels, higher resolution and improved performance makes the OV24A sensors an ideal camera solution for front- and rear-facing camera applications in high-end smartphones, says the firm.
The 24-megapixel (Mp) OV24A sensors are built on the PureCel Plus stacked die architecture, which enables higher-resolution pictures and video in a compact form factor.
The OV24A sensor family consists of three individual products: the OV24A1Q, OV24A1B and OV24A10.
All three versions of the OV24A sensors can support phase-detection autofocus.
The OV24A1Q, with its unique 4-cell color filter pattern, is ideal for front-facing camera applications. This sensor has an on-chip, in-pixel binning feature that captures four times more light photons than a regular 0.9-micron pixel. The result is higher image quality in low-light conditions.
Additionally, an application can recover an image to full 24Mp resolution, when paired with OmniVision’s software solution.
The OV24A1B (monochrome) and OV24A10 (Bayer) are used for main-camera and/or dual-camera configurations, enabling zoom and Bokeh features, and improved low-light performance.
The OV24A1Q fits high 24Mp resolution into the slim 1/2.8″ smartphone form factor for front-facing selfie cameras.
Additionally, increasing image quality for the rear-facing main smartphone camera remains of the utmost importance to most consumers.
When it is paired in a dual-camera configuration, the OV24A10 and/or OV24A1B sensors’ 24Mp resolution provides a higher zoom ratio, portrait mode effect, and higher quality still images and video in low light.
High dynamic range (HDR) is also very important for excellent camera performance, including both video chat and still photos. The OV24A1Q and OV24A10 provide HDR for an enhanced user experience. These sensors can capture still HDR images, as well as HDR video with full resolution at 30 frames per second, said the company.
“Smartphone image quality is essential to many consumers, and social media has particularly inspired millennials to make good use of high-resolution front-facing cameras,” said James Liu, product marketing manager at OmniVision. “Our OV24A image sensor family was developed to address the needs of these savvy consumers, who expect the highest quality stills and videos from their smartphones.”
The OV24A image sensor family is available now for sampling. It will also be demonstrated at CES 2018.
