Provided is a fluoroscopy apparatus including a fluorescence-image generating portion that generates a fluorescence image an identifying portion that identifies a position of a high-luminance region in the fluorescence image a storage portion that stores the position of the high-luminance region a detecting portion that detects an amount of change in a physical quantity, which can possibly act as a cause of changes in a property of the high-luminance region, starting from a time at which the position of the high-luminance region is identified by the identifying portion a confidence-level calculating portion that calculates a confidence level of the property of the high-luminance region based on the detected amount of change and a display-image generating portion that generates a display image in which the display mode at the position of the high-luminance region is set in accordance with the confidence level.
