Samsung Electronics South Africa, 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 digital single-lens reflex (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.
“With 12 million pixels working as a phase detection auto-focus (PDAF) agent, the new image sensor adds professional auto-focus performance to mobile devices, such as the Galaxy S7 and Galaxy Note 5,” said Craige Fleischer, Director of Integrated Mobility at Samsung Electronics South Africa. “Consumers will be able to capture their daily events and precious moments instantly on a smartphone, regardless of lighting conditions.”
Samsung’s new image sensor with Dual Pixel technology employs two photodiodes located on the left and right halves of a pixel. The conventional image sensor commits less than five percent of its pixels, with only one photodiode each, which converts light particles into measurable photocurrent for phase detection. Significantly faster auto-focus is now possible, as each and every pixel of the Dual Pixel image sensor is capable of detecting phase differences of perceived light. With such groundbreaking improvements, the image sensor ensures clear and sharp images, especially whilst capturing moving objects, even in poor lighting conditions.
The new image sensor has also adopted Samsung’s ISOCELL technology, which isolates the photodiodes in each pixel with a physical wall to further reduce colour bleeding, maximizing the image sensor’s performance.
The new image sensor is built with cutting-edge, chip-stacking technology that allows for top-of-the-line performance while keeping the size small. The Dual Pixel image sensor combines a 65 nanometer (nm) sensor with a 28nm logic chip that delivers outstanding quality photos in a sleek smartphone design.
