Samsung New ISOCELL HP3 200 MP Digital camera Sensor

Samsung continues to announce ultra-high decision digicam sensors aimed toward reasonably priced markets. The corporate simply launched the Samsung ISOCELL HP3, a 200 Megapixel digicam sensor that includes exceptionally small sensing pixels. The factor is: smaller pixels aren’t at all times higher, as their measurement makes it more and more harder to assemble pictures.

Every pixel is barely 0.56 μm (sq.), which is tiny, so there’s a 4:1 pixel-binning mode that may equate to a 50 Megapixel sensor with 1.12μm pixels, or perhaps a 16:1 pixel binning that approximates a 12.5 MP sensor with 2.24μm pixels.

It’s also very spectacular that the sensor options quarter-resolution pixel-level section detection autofocus. Every group of two×2 pixels requires an insanely small lens to attain that.

Samsung calls this its pixel-binning characteristic “Tetra pixel,” however the precept is identical as we’ve seen earlier than. Every sensor maker has a special implementation and would create a model, maybe for mental property or advertising causes.

It’s essential to grasp that binning sixteen 0.56 μm pixels into one digital 2.24μm pixel isn’t the identical as one bodily 2.24μm pixel. That’s as a result of every 0.56 μm pixel requires some supporting electronics, and a few sensing space of the chip could be misplaced to that. The extra pixels you may have, the extra wires and different issues may eat up some sensing space.

The extra electronics may additionally improve the prospect of introducing (digital) noise which may have an effect on the sensor’s efficiency. Smaller pixels may additionally have an effect on the efficient dynamic vary of the sensor, however luckily, that could be compensated by capturing extra HDR frames utilizing stacked pictures.

Up to now, we’ve seen degrading efficiency with some 0.7 μm, so I’m wondering if this sensor would stumble upon related points.

These ever-smaller pixels permit smartphone OEMs to market reasonably priced digicam telephones with excessive Megapixel specs. That mentioned, it stays to be seen if we’re going to see proportional picture high quality good points, particularly in low-light.

Nonetheless, relying on the place it’s used, this sensor may very well be an enchancment over previous sensors on the identical worth level. For instance, it may very well be barely bigger or able to quicker readouts, permitting 8K recording (or 4K in slow-motion) smartphones at a given worth vary weren’t able to earlier than.
