By the end of the year, we will find smartphones equipped with 64-megapixel sensors, and Samsung is the first to draw his own. In high or low light, this photosensor promises clichés close to the vision of the human eye.
Barely enough time to discover the 48-megapixel sensors that Samsung draws the model above: 64 megapixels! Never the last to compete with the competition, the Korean giant has unveiled the aptly named 64-megapixel Isocell Bright GW1, a sensor dedicated to smartphones, and it should equip the high-end models by the end of the year. the year 2019.
First, it must be remembered, a buildup of megapixels does not necessarily mean better quality images. In this case, to get these millions of additional pixels on a sensor slightly more full than the one at 48 megapixels, Samsung has trimmed the size of the pixels.
They do so 0.8 microns, and if it’s perfect outside and in normal conditions of light, however, is too just for photos at night or in low light. To overcome this handicap, Samsung takes advantage of Tetra cell technology to merge 4 pixels into one. No need to pull out the calculator, you get a pixel of 1.6 microns, wider to capture the light and at the same time a shot of a resolution of 16 million pixels.
Get closer to the vision of the human eye
Another evolution is the dynamic range of HDR. “For taking pictures that look like the way the human eye perceives its environment in a mixed-light climate, GW1 supports a real-time high-dynamic range (HDR) of up to 100 decibels (dB) that provides more consistent hues.
Rich, writes Samsung. In comparison, the dynamic range of a conventional image sensor is about 60 dB, while that of the human eye is generally considered to be about 120 DB.”
Finally, the video part is not forgotten since this sensor will be able to film in 4K and will be able to record full-HD videos in slow motion up to 480 fps.
