Apparatus for obtaining fluorescence images, and computer executable program therefor

摘要

When a diagnosis is to be performed using a fluorescence diagnostic image obtained by use of an endoscope apparatus or the like, if obstructing regions containing an obstructing factor such as blood or waste is present on the target subject, the misrecognition thereof as a diseased tissue is prevented. White light and excitation light are projected onto a target subject to obtain respective standard and fluorescence images thereof. Because the color of the obstructing regions is different from that of either normal or diseased tissue, the color data of the standard image is computed, and the obstructing regions detected by determining whether or not the color data is outside a predetermined range. The fluorescence image is subjected to an exceptional display process of rendering the color of the obstructing regions a different color than that of the other regions, and the processed fluorescence diagnostic image is displayed on a monitor. <IMAGE>
