This multicolor-fluorescence-image analysis device has the following: a photoexcitation light source; illumination optics that gather light from said light source and illuminate a sample; fluorescence collection optics that collect light in order to detect fluorescence or the like emitted by the sample; a separation unit that splits the collected light using different ratios; imaging optics that form respective images from the split light; a two-dimensional detector provided with a plurality of detection pixels for detecting the respective formed images; and a data processing unit that has an added-image-forming processing unit that adds the detected images together, a ratio-image-forming processing unit that calculates the ratio between one image and the added image, and an image-forming processing unit that generates a synthetic color image using the intensity of the ratio image as the hue component thereof and the intensity of the added image as the value component thereof.
