Backside illumination (BSI) technology is a type of imaging technology that enables a camera to have great clarity, no matter the brightness of the environment. BSI works by reversing the traditional imaging process by placing the image sensor behind the lens instead of in front. The light then enters the lens and travels through a microlens array before reaching the light sensitive pixel. The microlens array determines the direction of the light and redirects it so that it hits the pixel from the back side. This technology allows the most light to reach the image sensor, creating a brighter image.

BSI technology is used in a variety of cameras and devices, such as smartphones and tablets. By adopting a BSI imaging system, users are able to capture clear images, even in low-light conditions. BSI sensors are also known for having higher sensitivity, thanks to their microlens array. This technology is ideal for capturing photographs in difficult conditions, such as in low-light environments or in well-lit conditions.

In smartphones, BSI technology is used in the main camera which takes the user’s everyday photos. The technology helps to capture images without blurs, even in dimly lit conditions. In tablets, BSI technology is used in the front camera which is used for taking selfies. The technology helps to capture clear and crisp images, no matter the lighting conditions.

In summary, backside illumination (BSI) technology is a type of imaging technology that helps to capture clear and bright images no matter the environment. It is used in a variety of devices such as smartphones and tablets and is ideal for capturing photographs in difficult conditions.
