IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, INFORMATION PROCESSING PROGRAM, FLUORESCENCE OBSERVATION SYSTEM, AND FLUORESCENCE NAVIGATION SURGERY SYSTEM
An information processing apparatus includes a storage unit, a cutting-out unit, and a display controller. The storage unit is configured to store an image of fluorescence emitted from an observation target area of a living body in a recording medium as a fluorescence image of the observation target area, the image of fluorescence being captured with a first definition, the image of fluorescence being obtained by applying excitation light to the observation target area to which a fluorescent reagent is added in advance. The cutting-out unit is configured to cause a user to select at least a partial area of the fluorescence image and to cut out the selected area as a fluorescence image of a ROI area. The display controller is configured to cause a display unit to display the fluorescence image of a ROI area with a second definition that is lower than the first definition.
