Abstract: Provided is an information sharing system including at least one processor configured to: acquire a use status of use by each of a plurality of users for each of a plurality of functions relating to an information sharing service for sharing information; and execute, for each of the functions, predetermined processing relating to the function based on the use status of the function.

Abstract: An image processing apparatus includes a processor. The processor receives endoscope images to be determined, in each of which an image of an inside of a body of a subject is picked up, determines whether or not an endoscope image for comparison concerning a predetermined inspection site, and the endoscope images to be determined are same or similar, determines whether or not an observation mode of each of the endoscope images to be determined is a condition suitable for automatic recording, and automatically records a predetermined number of the endoscope images to be determined in a recording unit, when the endoscope images to be determined and the endoscope image for comparison are determined to be the same or similar and when the observation mode is the condition suitable for automatic recording.

Abstract: A capsule endoscope includes: an image sensor configured to generate an image by capturing inside a subject at an imaging frame rate that is variable; and a processor comprising hardware, the processor being configured to determine whether the image is a first image whose feature amount related to a region having a bubble or a residue imaged is equal to or greater than a predetermined amount, and change the imaging frame rate based on a determination result.
