Abstract
A reduced area imaging device is provided which utilizes selected charge integration periods. Various configurations of the imaging device are provided which locate the elements of the imagine device at desired locations. Regardless of the particular arrangement or configuration of the imaging device, selected charge integration periods are incorporated. The imaging device can be defined as a CMOS-CID device wherein a user may select an appropriate integration period in order to enhance the viewed image to a desired level of brightness. Particularly in fluorescence guided endoscopy and fluorescence assisted surgery, the ability to vary and select particular charge integration periods improves these processes.
