Abstract: A program causes a computer to execute processing including: acquiring an endoscope image captured by an endoscope; inputting the acquired endoscope image into a plurality of learning models learned so as to output diagnosis support information regarding a lesion included in the endoscope image; acquiring a plurality of pieces of diagnosis support information output from each of the learning models; and outputting a plurality of pieces of the acquired diagnosis support information and information regarding each of the learning models in association with each other. Alternatively, the program causes the computer to execute the processing of inputting the acquired endoscope image into one learning model, executing a plurality of determination logics to acquire a plurality of pieces of output diagnosis support information, and outputting a plurality of pieces of the acquired diagnosis support information and information regarding each of the learning models in association with each other is executed.

Abstract: Provided are an endoscope system, a processor, a diagnostic support method, and a computer program. A plurality of images are captured at different focal positions on an object, an evaluation value indicating a degree of focus is calculated for each of corresponding sub-regions among the plurality of captured images, a captured image including a sub-region having the highest degree of focus is determined among the plurality of captured images based on the calculated evaluation value, a distance to a region on the object corresponding to the sub-region is calculated, distance information is generated by calculating a distance to a plurality of regions on the object corresponding to the sub-region, a feature region is extracted from the captured image, diagnostic support information for the object is generated based on the distance information and a feature parameter associated with the feature region, and the generated diagnostic support information is output.
