With its Galaxy S20 Ultra smartphone, Samsung broke the 108-megapixel barrier on a phone camera for the first time, however the company does not plan to cease there.
In a blog post on Samsung's website, Samsung's head of sensor business crew Yongin Park outlines — in broad phrases — the corporate's formidable plans for picture sensors, and a few of the obstacles it wants to beat to attain them.
"As a way to match thousands and thousands of pixels in at the moment’s smartphones that characteristic different cutting-edge specs like excessive screen-to-body ratios and slim designs, pixels inevitably need to shrink in order that sensors may be as compact as attainable. On the flip aspect, smaller pixels may end up in fuzzy or boring photos, as a result of smaller space that every pixel receives mild info from. The deadlock between the variety of pixels a sensor has and pixels’ sizes has develop into a balancing act that requires stable technological prowess," he explains.
Samsung has been in a position to steadiness between these two points with its Isocell tech, which isolates pixels with particular materials to stop the sunshine escaping to neighbouring pixels. The corporate later launched Tetracell and Nonacell applied sciences, which use 2x2 and 3x3 pixel arrays to significantly improve the quantity of sunshine absorption on particular person pixels. Lastly, Samsung additionally lowered the pixel measurement to 0.7μm, one thing Park claims it was broadly believed to be inconceivable.
So, how far will Samsung go? Park mentions a 600-megapixel sensor, although he does not supply many particulars. It is not nearly smartphones, he says; main purposes for picture sensors are "anticipated to broaden quickly into different rapidly-emerging fields comparable to autonomous automobiles, IoT and drones."
Apparently, which means that sooner or later, these sensors can be in some methods extra highly effective than our eyes, which Park says match a decision of "round 500 megapixels." Sooner or later, "we'd even have sensors that may see microbes not seen to the bare eye," he says.
