1. A processing device comprising:
a processor comprising hardware, the processor being configured to:
acquire a captured image of an inside of a lumen;
acquire lumen structure information indicating a structure of the lumen;
determine whether the captured image can be analyzed or not and output analysis allowability/non-allowability information indicating whether the captured image is in an analysis allowable state or not based on the captured image and first determination criteria;
associate the analysis allowability/non-allowability information with the structure of the lumen based on the analysis allowability/non-allowability information and the lumen structure information to identify an analyzable portion and an unanalyzable portion of the structure of the lumen; and
determine that a portion of the identified unanalyzable portion determined to meet second determination criteria is a missed portion based on position and orientation information of a distal end of an insertion section to be inserted in the lumen,
wherein:
the lumen is an intestinal tract; and
in a case where the insertion section is inserted into a depth of the intestinal tract and then pulled out while capturing an image of the intestinal tract, the second determination criteria is criteria that a portion is unobservable unless reinserting the insertion section into the depth.
