Samsung Announces New 64MP ISOCELL Camera Sensor for Smartphones

The Samsung GW1 64MP camera sensor

At this point, unless Sony launches its own 64-megapixel chip, Samsung holds smartphone sensor bragging rights.

As for the 48MP - that's a minor update over the existing GM1, that's supposed to utilize the collected light more efficiently in bright environments and offer better autofocus thanks to what Samsung calls Super PD. Phone manufacturers have contentiously upped the ante in the past years and Samsung is looking to bring the latest breakthrough in mobile photography with its 64MP ISOCELL Bright GW1 sensor.

The new ISOCELL Bright GW1 sensor beats Samsung's and Sony's 48 megapixel IMX586 in terms of pixel count but, but that is about all the differences, as the three have something in common, albeit different names and more pixel counts. This one also features Tetracell technology that will massively improve shots in low-light environments and a remosaic algorithm. It does that by merging four pixels into one while the color filter is descrambled for full-resolution 64-megapixel shots in good lighting. The dynamic range of a conventional image sensor is around 60dB while that of the human eye is typically around 120dB. If the claims by Samsung are correct, then any phone using the ISOCELL GW1, would be the new dynamic range leader in camera and imaging.

The GW1 also comes with a Dual Conversion Gain (DCG) that uses light more effectively in a bright environment. The built-in Super PD allows sharper results, better PDAF, and full HD video recording at 480fps. Samsung said it will accelerate technology development in image sensors for smartphone cameras to grab a bigger share of the growing market.

Both these sensors will be available in mobile devices later this year. It is quite possible that these sensors could make their way to the upper rungs of the Samsung A series or even the Samsung Galaxy Note 10.
