The present technology relates to an endoscope system, an endoscope control method, and a program that allow AF processing to be performed without deterioration in accuracy.

Provided are a drive unit that drives a lens, a measurement unit that measures a position of the lens, and a control unit that controls focusing, the control of the focusing including setting a control amount of wobbling at the time of the focusing on the basis of first hysteresis that is held and second hysteresis that is measured upon energization. The measurement unit includes a sensor that measures the position of the lens by detecting passage of the lens. The present technology is applicable to a medical observation device such as an endoscope or a microscope.

A stereoscopic imaging apparatus and platform are disclosed. An example stereoscopic imaging apparatus includes a main objective assembly and left and right lens sets defining respective parallel left and right optical paths from light that is received from the main objective assembly of a target surgical site. Each of the left and right lens sets includes a front lens, first and second zoom lenses configured to be movable along the optical path, and a lens barrel configured to receive the light from the second zoom lens. The example stereoscopic imaging apparatus also includes left and right image sensors configured to convert the light after passing through the lens barrel into image data that is indicative of the received light. The example stereoscopic visualization camera further includes a processor configured to convert the image data into stereoscopic video signals or video data for display on a display monitor.

A medical imaging device including at least two cameras. The medical imaging device includes an elongated and narrow distal tip connected to a rigid elongated shaft member, wherein the distal tip includes a front camera and a first side camera. The cameras of the disclosed medical imaging device can be configured to provide variable cameras' magnifications, which in some cases may vary from one camera to another. The cameras of the medical imaging device may be provided with dissimilarity in the cameras' magnification factors. Such dissimilarities are used to show the same object in the same size in a panoramic image captured simultaneously by the multiple cameras, as the multiple cameras have multiple distances to the object.

A stereoscopic camera with fluorescence visualization is disclosed. An example stereoscopic camera includes a visible light source, a near-infrared light source, and a near-ultraviolet light source. The stereoscopic camera also includes a light filter assembly having left and right filter magazines positioned respectively along left and right optical paths and configured to selectively enable certain wavelengths of light to pass through. Each of the left and right filter magazines includes an infrared cut filter, a near-ultraviolent cut filter, and a near-infrared bandpass filter. A controller of the camera is configured to provide for a visible light mode, an indocyanine green (“ICG”) fluorescence mode, and a 5-aminolevulinic acid (“ALA”) fluorescence mode by synchronizing the activation of the light sources with the selection of the filters. A processor of the camera combines image data from the different modes to enable fluorescence emission light to be superimposed on visible light stereoscopic images.

A device for attaching an optical element, such as an otoscope, to a smart phone for diagnosing and/or identifying problems of an outer ear, a middle ear, and/or an ear canal of a patient. The device may comprise a main body. The main body may comprise an aperture and a first engagement member configured to engage with a second engagement structure that belongs to the optical element. A first surface may be connected to the main body and configured may be to contact a first smart phone surface. A piston may be provided that may comprises a second surface that may be parallel to the first surface and may be configured to contact a second smart phone surface. A threaded knob may be provided and may be connected to the piston through the aperture.

This camera module comprises: an imaging element which is formed in a rectangular shape and to which is provided a plurality of pads on the rear, which is the reverse side from the image capture surface; a wire positioning/fixing body which fixes together a plurality of parallel wires extending in a direction approximately perpendicular to the rear surface, and has each of the conductors of the wires protrude from the opposing end surface which is parallel to the rear surface in accordance with to each of the pads; and electro-conductive materials which conduct electricity from the tip of the conductors to each of the plurality of pads.
