"The new, cost-efficient OV6920 is the only 1/18-inch sensor available, offering low power operation for use in disposable cameras for medical applications such as intubation and diagnostic systems. The 2.1 mm by 2.3 mm CSP packaged chip will enable a 3.2 mm diameter microscopic camera module, making many medical procedures even less invasive for the patient. It also allows certain medical devices such as intubation systems and endoscopes to be made even smaller to allow for use on infants and small children."
