The 1/2.6-inch PureCel-S™ OV13860 image sensor uses large 1.3-micron pixels and leverages OmniVision's new stacked die technology to deliver exceptional low-light performance while meeting the design constraints of low z-height camera modules.
"Today's smartphone OEMs are conscious of the fact that users expect higher resolution cameras in their smartphones. But this increase in resolution is often accomplished by a reduction of pixel sizes, which results in a loss of camera performance and low-light sensitivity," said Bahman Hadji, product marketing manager at OmniVision. "The OV13860 is the ideal solution to this dilemma: a unique 1/2.6-inch 13-megapixel sensor with 1.3-micron pixels – 35 percent larger in size than traditional 13-megapixel sensors. Despite its 1/2.6-inch optical format, the OV13860 uses a high chief ray angle (CRA) to enable a camera module z-height of 5.5 mm, suitable for today's slim smartphones. With its large pixels and high CRA, the OV13860 provides an extraordinary 'no-compromise' imaging solution for next-generation flagship smartphones."
The PureCel-S™ OV13860 is the first in OmniVision's family of high-performance backside-illuminated PureCel™ image sensors to leverage the company's stacked die technology, which separates the imaging array from the image sensor processing pipeline into a stacked die structure. This allows for additional functionality to be implemented on the sensor while providing for a much smaller footprint when compared with non-stacked sensors, thus enabling smaller module sizes for larger optical format sensors.
Among the OV13860's advanced features is autofocus contrast calculation at an extremely fast 120 frames per second (FPS) while imaging at full 13-megapixel resolution to enable a fast autofocus camera system. When paired with a high-speed actuator, the OV13860 can provide for nearly instant autofocus by delivering contrast statistics at up to four times faster than traditional single frame-based contrast calculations. The OV13860 also supports alternate row dual-exposure high dynamic range (HDR) timing mode for delivering HDR video in challenging lighting scenes.
The OV13860's large 1.3-micron pixels enable dramatically improved high- and low-light performance as a result of higher sensitivity, signal-to-noise ratio, and full-well capacity when compared to products of similar or higher resolution with 1.12-micron pixels. The OV13860 can capture full-resolution 13-megapixel still images at 30 FPS or record ultra-high resolution 4K2K video at 30 FPS, 1080p full HD at 60 FPS, or 720p HD at 120 FPS. Each video output format includes additional pixels to support electronic image stabilization (EIS).
