Abstract: A diagnosis assisting apparatus includes a region extraction section configured to extract, from among fluorescence images obtained by picking up images of fluorescence emitted from a desired object, a reference region to be handled as a reference for a fluorescence generation state and a region of interest to be handled as a comparison target of the fluorescence generation state, respectively, a calculation processing section configured to acquire a reference value corresponding to a luminance value of each pixel included in the reference region and calculate a calculation value obtained by dividing the luminance value of the region of interest by a representative value, a storage section configured to store the calculation value calculated by the calculation processing section, and an image processing section configured to cause a display apparatus to display information indicating a variation over time of the calculation value stored in the storage section.
