In relation to smartphone photography, high-resolution, giant sensors are the way in which to go ahead. OmniVision’s new breakthrough manages to do exactly that after which some.
Over the previous few years, part producers have shifted focus to creating bigger picture sensors with increased decision and greater particular person pixels. Nevertheless, attaining development on all three fronts comes with bodily constraints equivalent to measurement and weight. Thus, options equivalent to pixel-binning have been launched to supply flexibility.
The brand new OmniVision OV64A picture sensor takes that to the following degree by packing a 64MP decision throughout a big 1/1.32-inch picture sensor with 1.0µm pixel measurement. For comparability, Samsung’s standard ISOCELL HM1 picture sensor spans 1/1.33-inches however has considerably smaller pixels owing to the 108MP decision.
OmniVision claims that the brand new sensor with 1.0µm pixels is 60% delicate to gentle than its older 64MP sensor with 0.8µm pixels. Quad Bayer pixel-binning can take the pixel measurement to 2.0µm for 16MP resultant pictures. An fascinating characteristic is the flexibility to shoot movies (at as much as 4K decision) on the similar degree of binning for significantly better low-light efficiency in addition to lossless digital cropping.
Different taking pictures modes embody 64MP seize at 15fps, 8K video at 30fps, 4K video at 120fps with EIS, 4K video at 60fps with 4C binning, 1080p at 240fps and extra.
The OV64A sensor additionally helps 2- and 3-exposure staggered HDR timing choice, providing extra flexibility to OEMs. The PureCel Plus-S stack additionally permits on-chip 3-exposure and tone-mapping on the chip. That is sooner than offloading the processing to the telephone’s chipset.
The part samples are actually obtainable to smartphone corporations. Mass manufacturing is anticipated to start later this yr. “TSR estimates there can be 322 million picture sensors with 50MP or increased decision shipped to smartphone producers in 2021, which presents an enormous alternative for OmniVision’s rising 64MP portfolio,” mentioned Arun Jayaseelan, workers advertising supervisor at OmniVision.
