After teasing it earlier this week, Samsung has revealed the details of the ISOCELL JN1, a 1/2.76-inch (6.5mm) 50MP smartphone camera sensor that appears to have the smallest pixels in the industry, at least as far as mass-produced image sensors are concerned, at just 0.64μm.
Samsung says it opted for smaller pixels to shrink the size of the sensor to make it more versatile for device manufacturers. Specifically, Samsung says the sensor should reduce the size of camera modules by up to 10% and will work for front-facing, telephoto, ultra-wide and other camera modules inside mobile devices.

Aside from the small pixels, the ISOCELL JN1 uses other Samsung technologies introduced in previous sensors. First up is an enhanced version of its ISOCELL 2.0 in the JN1, which it claims improves ISO sensitivity performance by up to 16%. Samsung has also added its second-generation phase-detection autofocus tech it calls ‘Double Super PDAF.’ Samsung says this new iteration has twice the density of phase-detection pixels, which offers the same AF speed in up to 60% lower light compared to the original Super PDAF technology.
Other technologies inside the JN1 include Samsung’s Tetracell pixel-binning technology and Smart-ISO. In addition to 50MP stills, the JN1 can capture 4K video at up to 60 frames per second (fps) or Full HD (1080) video at up to 240 fps.
Samsung hasn’t revealed any device manufacturers it’s in talks with to use the new ISOCELL JN1 sensor, nor when we can expect to first see it in consumer devices but does note it’s ‘currently in mass production.’
