Single-chip sensor multi-function imaging

摘要

Mixed mode imaging is implemented using a single-chip image capture sensor with a color filter array. The single-chip image capture sensor captures a frame including a first set of pixel data and a second set of pixel data. The first set of pixel data includes a first combined scene, and the second set of pixel data includes a second combined scene. The first combined scene is a first weighted combination of a fluorescence scene component and a visible scene component due to the leakage of a color filter array. The second combined scene includes a second weighted combination of the fluorescence scene component and the visible scene component. Two display scene components are extracted from the captured pixel data in the frame and presented on a display unit.
