An information processing device (100) is provided with a generation unit that acquires an input image serving as an intraoperative image and generates an output image based on whether the input image includes an intraoperatively generated matter or not.

A first illumination light beam is switched to a second illumination light beam and the second illumination light beam is emitted for a period of at least one frame, during a period in which the first illumination light beam is emitted. A first image or a second image obtained by imaging an observation target illuminated with the first illumination light beam or the second illumination light beam is acquired for each frame. At least one first image and at least one second image that satisfy a preset selection condition are selected and stored from a plurality of the first images and a plurality of the second images acquired in a preset period prior to a time of a processing start operation of image storage processing.

An endoscope system includes: an insertion body inserted into a lumen; an objective optical system that is provided in the insertion body and acquires light from a subject as subject light; an image sensor that performs imaging based on the subject light to acquire a captured image within a field of view; a turning mechanism that causes a distal end of the insertion body to rotate around a reference axis that is an axis of the insertion body; an advancing/retreating mechanism that moves the insertion body in a direction corresponding to the reference axis; and a processor that includes hardware and is configured to control the turning mechanism and the advancing/retreating mechanism to control the field of view of the image sensor. The processor controls the turning mechanism and the advancing/retreating mechanism to perform scan of an inner wall of the lumen based on the field of view.

In a phase adjustment circuit, a binary circuit is configured to output a binary signal on the basis of an edge of a video signal. A phase-delayed clock signal generation circuit is configured to generate a phase-delayed clock signal having a later phase than a phase of a clock signal by a first delay amount. A delay time control circuit is configured to cause a phase of the binary signal and the phase of the phase-delayed clock signal to match each other by adjusting the first delay amount. A sampling signal generation circuit is configured to generate a sampling signal having a later phase than the phase of the clock signal by a second delay amount. The second delay amount is in accordance with both a phase shift amount, which is based on the clock signal, and the first delay amount.

An endoscope includes a housing with a distal end insertable into a cavity; an image capture device at the distal end to obtain 3D images, and process them to form a video signal; and a folded substrate folded into a U-shape having first and second legs. The image capture device includes a detector and a lens system with right and left multi-band pass filters having right pass bands that are complements of left pass bands. The lens system receives the 3D images including right and left images. The detector faces the lens system to obtain the right and left images. A processing circuit faces the proximal end behind the detector to process signals from the detector. The folded substrate includes the detector at an outer side of the first leg facing the lens system and the processing circuit at an outer side of the second leg facing the proximal end.
