Abstract: An endoscope system includes a first capsule endoscope device and a second capsule endoscope device. The first capsule endoscope device is introduced into a living body before the second capsule endoscope device is introduced. The first capsule endoscope device includes a first image sensor and a first processor that controls an imaging operation by the first image sensor. The second capsule endoscope device includes a second image sensor and a second processor that performs a change process for control on an imaging operation by the second image sensor based on first information on the first capsule endoscope device.

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.

Abstract: An endoscope system includes an image acquisition section, an attention area setting section, and a scaling section. The image acquisition section acquires a captured image that includes an object image. The attention area setting section sets an attention area within the captured image based on information from the endoscope system. The scaling section performs a local scaling process that relatively enlarges the attention area as compared with another area.

Abstract: An endoscope apparatus includes comprises a processor. The processor causes the light source device to produce narrow band light as illumination light, and the narrow band light has a peak wavelength between a wavelength band including a local maximum of a hemoglobin absorption characteristic and a wavelength band including a local minimum of the hemoglobin absorption characteristic. The processor receives an image signal from the imaging device that outputs the image signal based on return light. The processor uses an image produced in response to the image signal to identify a state of the living body by identifying at least one of whether or not stomach mucosa is in a sterilized state, or whether or not the stomach mucosa is inflamed mucosa, outputs state identifying information indicating the state of the living body, and controls wavelength characteristics of the illumination light based on the state identifying information.

Abstract: An endoscope apparatus includes: a light source device alternately emitting a first illumination light group including green light and a second illumination light group not including the green light; an image sensor including color filters of a plurality of colors; and a processing circuit. The processing circuit generates a display image on the basis of an image obtained with the first illumination light group and an image obtained with the second illumination light group. The first illumination light group further includes blue narrowband light together with the green light. The processing circuit generates a green channel image in the display image on the basis of a green image and a blue narrowband image.

Abstract: An endoscope system includes an image acquisition section, an attention area setting section, and a dimming control section. The image acquisition section acquires a captured image that includes an object image. The attention area setting section sets an attention area within the captured image based on information from the endoscope system. The dimming control section performs a dimming control process that controls the intensity of illumination light based on the attention area set by the attention area setting section.
