Real time, low-light images, for example, obtained from the fluorescent marker for identifying tumors during surgery, are combined to improve the signal-to-noise ratio using a motion signal derived from corresponding high-light images, for example, taken with a second camera at interleaved intervals of higher illumination.

Fluorescent markers used to identify a tissue may be imaged in a bright environment by synchronizing the imaging process with rapidly switched ambient lighting so that imaging occurs in phase with a switching off of the ambient lighting. In this way, valuable fluorescent imaging may be performed in an environment that appears to be brightly illuminated, for example in the area of a surgical suite.
