BICin

BICin refers to a specific type of camera module used in some smartphones, notably those manufactured by the Chinese company Xiaomi. The term "BICin" is an abbreviation derived from "BSI CMOS," indicating that the camera sensor utilizes Back-Side Illumination (BSI) technology and is a CMOS (Complementary Metal-Oxide-Semiconductor) image sensor. BSI technology is a design improvement over traditional front-side illuminated sensors, where the photodiodes and transistors are layered in a way that allows more light to reach the photodiode, resulting in better low-light performance and reduced noise. While the specific manufacturer of these BICin sensors is not always publicly disclosed, they are a component chosen for their ability to capture higher quality images, especially in challenging lighting conditions. The use of BICin modules is often highlighted in product specifications by manufacturers aiming to emphasize the camera capabilities of their devices.
