Abstract
A device and method for fluorescent imaging may include an imaging unit including a fluorescent camera with an optical detector that is configured to acquire a fluorescent image of a fluorescing sample, the image including raw pixel values. A user interface may display an image formed from display image pixels derived from the raw image pixels. A distance sensor may measure a distance to the fluorescing sample. A distance between the optical detector and fluorescing sample may be determined from the measured distance. A processing unit may obtain a gain value, match the determined distance to a distance value associated a respective gain range, and impose limits of the gain values range onto the gain value, to determine a limited gain value. The limited gain value may be applied to the raw image pixels, thereby deriving display image pixels.
