The algorithm can be configured to maintain "constant image brightness" (which results in lower power consumption) or to maintain "constant illumination power" (which results in higher image brightness).
The iSight camera includes video image stabilization and both cameras feature backside illumination to let users capture great pictures in low light. iPad mini also allows easy sharing of photos with friends and family using iCloud's Shared Photo Streams.
Toshiba implemented back side illumination (BSI) technology and integrated color noise reduction (CNR) to develop its newest CMOS image sensor that fits into an 8.5mm x 8.5mm size camera module and enables high-quality pictures even in low-light conditions.
