Abstract
A capsule endoscope includes an imaging device that captures time-series captured images and a processor including hardware. The processor implements a process that performs a first motion determination process with respect to the capsule endoscope based on the captured images to calculate a first motion determination result, and a communication process that transmits the captured images to an external device that is provided outside the capsule endoscope, and receives a second motion determination result, the second motion determination result being a result of a second motion determination process with respect to the capsule endoscope that was performed by the external device based on the captured images. The processor implements the process that controls the frame rate of the imaging device based on the first motion determination result and the second motion determination result.
