SYSTEM AND METHOD, IN PARTICULAR FOR MICROSCOPES AND ENDOSCOPES, FOR CREATING HDR MONOCHROME IMAGES OF A FLUORESCING FLUOROPHORE

摘要

A method and system for computing an HDR image (38) from a digital color input image (4) of an object (30) containing a fluorescing fluorophore (22) acquires the input image using a color camera (2) having at least two different types (16, 17, 18) of color sensor (8), such as an R, G and B sensor. The input image may be recorded in a co-sensing wavelength band (64, 66, 68) wherein different spectral responsivities (58, 60, 62) of the different types of color sensor overlap. The input image comprises different digital monochrome input images (6), each recorded by a different type of color sensor. Light incident on the camera may be filtered using a band-pass filter (32) having a tunable pass band (34) which defines the co-sensing wavelength band and may be adjusted depending on spectral responsivities of the color sensors, the fluorophore, and characteristics of the monochrome input images.
