Sony says that it created the IMX318 sensor for smartphones that require “increasingly better cameras and thinner form factors.” The IMX318 is the successor to the IMX230 that was found in the Xperia Z5 series (1/2.4-inch sensor with 1.12μm unit pixel size). Sony says that the new IMX318 does not suffer in image quality despite the smaller pixel size (1.0μm unit) versus the IMX230. It has done this by “manufacturing technology that improves light utilization efficiency, as well as circuit design technology that eliminates noise”.
Sony adopted MIPI (Mobile Industry Processor Interface) Alliance’s latest C-PHY 1.0/D-PHY 1.2 specifications for this image sensor’s interface. Other features include 4K video recording at 30fps, HDR imaging with RAW image format.
