An imaging system includes a mirror and an imaging device. The mirror includes a body and a conical hole formed in the body. An inner wall surface of the conical hole is a conical mirror. The imaging device faces a first opening of the conical hole and captures an image of a product in the conical hole. A light from a side surface of the product is reflected by the conical mirror to the imaging device and the imaging device captures a side surface image of the product.

An illumination optical system for endoscope includes a rod lens as an optical element. The optical element includes a proximal end surface through which light enters and a distal end surface configured to emit the light. The distal end surface includes a diffusion region configured to diffuse emitted light. The diffusion region includes a plurality of concave portions and a plurality of peripheral regions surrounding the concave portions. Each concave portion includes a plurality of inclined surfaces as total reflection surfaces that are inclined with respect to the distal end surface. Each peripheral region includes a transmission surface configured to emit light totally reflected by the total reflection surfaces after passing through the proximal end surface and light not totally reflected by the total reflection surfaces.

An endoscope system includes a light source unit, an image sensor, an image acquisition unit, a first image generation unit, a second image generation unit, and a region discrimination unit. The light source unit emits a plurality of types of illumination light beams with different wavelengths. The image acquisition unit acquires images corresponding to the respective illumination light beams. The first image generation unit generates a first image (white light image) serving as a base of a display image. The second image generation unit generates a second image (bright/dark region discrimination image or the like), using at least one image having a different corresponding wavelength from that of the image used for the generation of the first image. The region discrimination unit discriminates the regions in the observation target, using the second image.

An endoscope includes a light source coupled to emit light, and a lens disposed proximate to a distal tip of the endoscope tube and structured to absorb at least some of the light. A controller is coupled to the light source, and the controller includes logic that when executed by the controller causes the endoscope to perform operations, including adjusting an emission profile of the light source to heat the lens with the light, and heating the lens mitigates formation of fog on the lens.

The present disclosure provides systems and methods for medical imaging. The system may comprise a scope assembly. The scope assembly may comprise a housing unit configured to releasably couple to at least a portion of an elongated scope. The scope assembly may comprise an imaging unit operably coupled to the housing unit, wherein the imaging unit comprises an optics assembly configured to (i) receive one or more light beams that are transmitted through the elongated scope and (ii) direct at least a portion of the one or more light beams onto two or more locations within a subject's body. At least one of the two or more locations may comprise a target site. The imaging unit may be configured to move via a rotational and/or translational motion relative to the housing unit to alter a field of view when imaging within the subject's body.

Provided are an imaging device and an electronic apparatus capable of suppressing deterioration in performance due to charge accumulation. An imaging device includes: a photoelectric conversion layer having a first surface and a second surface located on an opposite side to the first surface; a first electrode located on a side of the first surface; and a second electrode located on a side of the second surface. In a thickness direction of the photoelectric conversion layer, when a region overlapping with the first electrode is defined as a first region, and a region deviating from the first electrode is defined as a second region, a first film thickness of the photoelectric conversion layer in at least a part of the first region is thinner than a second film thickness of the photoelectric conversion layer in the second region.

Imaging devices, imaging systems, and methods are presented for determining distances, depths, and sizes of a viewed tissue or object through a visualization device. The device may include an elongated shaft and an imaging component. The imaging component may extend through the elongated shaft. The imaging component may have a lens and may be configured to capture an image of an area exterior of the elongated shaft in a field of view of the lens. A transparent cover may extend over the lens. The transparent cover may be configured to cause one or more identifiers to appear in the image. The imaging device may include or be used with a computing device to analyze image data of captured images.

A trocar including a trocar head attached to a cannula having a lumen with a distal opening, the cannula includes at least one elastomeric band positioned across said lumen.

A tip part (2) for forming a tip of a disposable insertion endoscope (1) the tip part comprising: a camera insertion sleeve (28) provided within the interior spacing, the camera insertion sleeve being formed by a circumferential camera sleeve wall that extends from the distal front wall of the housing to a proximal end of the camera insertion sleeve so that the camera insertion sleeve comprises an open proximal end; a tube insertion sleeve (38) provided within the interior spacing and fixed in relation to the distal front wall, the tube insertion sleeve being formed by a circumferential tube sleeve wall that extends a total tube sleeve length S from the distal front wall of the housing to a proximal end of the tube insertion sleeve so that the tube insertion sleeve comprises an open proximal end; the circumferential housing wall comprises at least one cut-out (41) extending from the proximal end towards the distal front wall, the at least one cut-out leaving space for constructive elements within the at least one cut-out, such constructive elements comprising e.g. fixation, such as crimps, of steering wires and/or alignment elements for alignment of the tip part during manufacture. Furthermore, methods of manufacture thereof are disclosed.

In some embodiments, a stereoscopic imaging apparatus includes a tubular housing having a bore extending longitudinally through the housing. First and second image sensors are disposed proximate a distal end of the bore, each including a light sensitive elements on a face and mounted facing laterally outward. The apparatus further includes a first beam steering element associated with the first image sensor and a second beam steering element associated with the second image sensor. The beam steering elements receive light from first and second perspective viewpoints and direct the received light onto the faces of the image sensors forming first and second images. Either the first and second beam steering elements or the first and second image sensors are moveable to cause a change a spacing between or an orientation of the perspective viewpoints to cause sufficient disparity between the first and second images to provide image data including three-dimensional information.
