Phone Camera Technology

Mike Elgan praises the multitude of roles that camera sensors play in modern smartphone apps .

Elgan notes, "Already, smartphone cameras can identify and provide additional information about whatever we point them at. They enable us to harvest visual data from, and see augmented reality objects placed in, the real world. Front-facing cameras can improve security through face recognition" (para. 28). Elgan notes that cameras with multiple lenses are now the norm, and the number of sensors will only increase with apps such as Camfind and Photomath. -DD
