The First Smartphone Picture Sensor With 100% PDAF Protection Unveiled


The First Smartphone Image Sensor With 100 PDAF Coverage Unveiled

OmniVision Technologies claims to have developed the primary image sensor with 100% part detection autofocus (PDAF) protection designed for smartphones. The corporate says its new 50-megapixel sensor permits for improved distance calculation, quicker autofocus, and higher low-light efficiency.

This new sensor combines the excessive decision of fifty megapixels with 1.0-micron pixel dimension, selective conversion achieve, and a 1/1.5-inch optical format with quad part detection (QPD) autofocus know-how and on-chip re-mosaic. That QDP enabled OmniVision to make use of 2×2 phase-detection autofocus throughout the sensor’s whole picture space for true, 100% protection.

“Unlike the microlens and half-shield PDAF technologies, which only capture 3-6% of the phase-detection data, QPD uniquely captures 100% of this data,” the corporate writes. “In combination with on-chip remosaic for the QPD color filter array, the result is premium image quality for the wide and ultrawide main cameras in flagship and high-end smartphones.”

The corporate doesn’t cease at autofocus positive aspects and claims that its sensor additionally supplies the perfect low mild efficiency in its class. It does so by way of the mixture of the massive 1.0-micron pixel dimension, low noise due to selective conversion achieve, a excessive conversion achieve mode, and the bigger 1/1.5-inch dimension.

“Additionally, this sensor offers excellent HDR through 2- and 3-exposure staggered HDR timing, along with selective conversion gain for the optimum balance between low-light image quality and HDR,” Omnivision continues. “These features provide mobile designers with maximum flexibility to select the best HDR method for the contrasting light and dark areas in any scene.”

Constructed on OmniVision’s PureCel Plus-S stacked die know-how, the OV50A integrates an on-chip, QPD shade filter array and {hardware} remosaic, which the corporate says supplies considerably improved autofocus efficiency together with prime quality, 50-megapixel output or 8K video, in real-time. This sensor may also use near-pixel binning to output a 12.5MP picture for 4K video with 4 occasions the sensitivity, which OmniVision says yields a 2.0 micron-equivalent efficiency for preview and video.

Video could be ouput at as much as 30 frames per second in 8K, 60 frames per second in 4K, and 240 frames per second in 1080p Full HD.

“In either case, the OV50A can consistently capture the highest quality images, as well as enabling 2x digital crop zoom with 12.5MP resolution and fast mode switch,” the corporate writes.

OmniVision additionally says that the hole between full-size cameras (which it calls DSLRs in its press announcement) has steadily been shrinking, and the corporate claims that this development will additional serve to shut it.
