After launching its first 200 Mpx sensor less than a year ago without us having yet been able to see it in action, Samsung already intends to offer a new one with the Isocell HP3 which wants to offer a more compact format. .

This sensor offers a size of 1/1.4 inch with 0.56 μm pixels, the smallest in the industry today. The Isocell HP1 was a 1/1.22 inch sensor with 0.64 μm pixels. This 12% reduction in pixel size allows the photo module to take up 20% less space and thus offer less bulky modules.

The Isocell HP3 can also capture images in 14 bits and now supports a palette of 4000 billion colors. It has an autofocus called “Super QPD”. This solution ” uses a single lens on four adjacent pixels to detect phase differences in the horizontal and vertical directions for faster and more precise focusing.

It can shoot in 4K at 120 fps, but also in 8K at 30 fps. When recording in 8K, the loss of field of vision this time would be minimal compared to the 108 Mpx sensors currently used by Samsung.

Improved pixel binning technology

This new sensor uses a new technology ofpixel binningcalled “Tetra² pixels” which allows to capture 50 Mpx images with 1.12μm pixels (4 pixels in 1) or 12.5 Mpx images with a pixel size of 2.24μm (16 pixels in 1). According to the manufacturer, this allows in particular to have a better experience in low light situations.

It also includes a Smart ISO Pro function which will influence the ISO sensitivity of the sensor (that is to say its sensitivity to light) by intelligently adjusting the conversion gain according to the scene photographed to always have the best range. possible dynamic. Samsung is currently offering samples of the Isocell HP3 for testing and production is expected later this year.
