Samsung today unveiled its Dual Pixel imaging sensor for smartphones. Samsung says the 1.4 microns 12 megapixel sensor with Dual Pixel technology is already in mass production and is generally reserved for DSLR cameras that ensures amazing picture quality in low-light scenarios and fast auto focus.
Here’s the lowdown as to how Dual Pixel tech functions.
Samsung’s new image sensor with Dual Pixel technology employs two photodiodes located on the left and right halves of a pixel, while a conventional image sensor dedicates less than five percent of its pixels, with one photodiode each that converts light particles into measurable photocurrent for phase detection. As each and every pixel of the Dual Pixel image sensor is capable of detecting phase differences of perceived light, significantly faster auto-focus has become possible. With such groundbreaking improvements, the image sensor ensures clear and sharp images especially for moving objects even in poor lighting conditions.
Furthermore, the sensor is also equipped with ISOCELL that helps to reduce colour cross talk and is built by stacking a 65nm sensor and 28nm logic chip.
Galaxy S7 and Galaxy S7 edge are the first devices to make use of the Dual Pixel tech but this particular Samsung sensor may or may not be in your Galaxy S7 device as Samsung also uses Sony’s sensor in some of the variants.
