Samsung Electronics, a world leader in advanced semiconductor technology, announced its newest 12 megapixel (MP) image sensor for smartphones, which will elevate the quality of mobile phone pictures. Already in mass production, this 1.4μm-pixel-based image sensor is equipped with Dual Pixel technology that has been reserved for DSLR cameras. The technology enables rapid auto-focus for fast photo shooting while producing premium image quality on mobile devices, even in low light situations.
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.
Just to have a clear picture on what is the benefit of Dual Pixel Image sensor on your phone, here are some videos explaining the said technology:
The image sensor has also adopted Samsung’s ISOCELL technology, which isolates the photodiodes in each pixel with a physical wall to further reduce color cross talk, maximizing the image sensor’s performance.
