An apparatus, system and method for providing an image enhancing effect for a photographic image of a target region within an intravascular environment. The image enhancing effects may be a physical process based upon the nature of the detected light or based upon different aspects of expected light reflection behavior, for example, by running predefined image reconstruction algorithms. The apparatus has a plurality of different embodiments, each of which reduces the ambient "noise" detected along with the light reflected from the target region in order to increase the signal/noise ratio, thereby to enhance the quality of the image produced.
