There is provided a surgical controlling device including an exposure controlling section that performs exposure control based on a luminance detection value detected from a biological image, in which the exposure controlling section corrects, on the basis of information regarding an identified surgical optical device, the luminance detection value so as to correct luminance unevenness arising from the surgical optical device. Further, there is provided a control method including performing, by a processor, exposure control based on a luminance detection value detected from a biological image, in which the performing the exposure control further includes correcting the luminance detection value so as to correct, based on information regarding an identified surgical optical device, luminance unevenness arising from the surgical optical device.

A camera head includes: a mount detachably connected to an eyepiece of an endoscope; an imager configured to capture a subject image emitted from the eyepiece; and a housing configured to house the imager, the housing including an interior portion including the imager thereinside, and an exterior portion arranged on an outer side of the interior portion, wherein the interior portion and the exterior portion are separated from each other in at least a part of an outer surface.

Arthroscopes and laparoscopes are available in several lens cuts to cover different clinical situations of interest, with the surgeon having to exchange the optics in order to change the direction of view of the camera. The presently disclosed embodiments disclose real-time image processing systems and methods that enable the user to arbitrarily change the direction of view of a surgical camera with the advantage of avoiding the disruption in workflow caused by the physical exchange of the optics. In addition, the presently disclosed embodiments disclose performing zoom along an arbitrary viewing direction (directional zoom) that enables to increase the scale of a region of interest without decreasing the overall field-of-view or losing image contents.

An imaging device for use with an endoscope, the imaging device comprising: a lens arrangement operable to receive light from a scene captured by the endoscope and to form an image of the scene using the received light; an image sensor operable to capture the image of the scene formed by the lens arrangement; a birefringent device positioned along an optical path between the endoscope and the image sensor, wherein the birefringent device comprises birefringent material arranged in a plurality of concentric rings, and wherein the birefringent material of each of the concentric rings is configured such that the polarisation directions of an ordinary ray and an extraordinary ray of light from the scene which travels through the birefringent material are different for at least two of the plurality of concentric rings; and an image processor operable to process the captured image to generate an output image.

The present invention relates to an endoscope including an object, which is to be supplied with electric current, in an endoscope head of the endoscope, and a circuit board for the object to be supplied with electric current. The circuit board extends from the object, which is to be supplied with electric current, in the distal direction of the endoscope head.

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.

An image processing device includes: a processor including hardware. The processor is configured to: obtain images captured by an imaging element configured to perform imaging at a higher frequency than a vibrational frequency of a subject; detect the vibrational frequency of the subject based on the obtained images; set a selection period that is longer than a vibration period of the subject; sequentially select, from among the obtained images, images to be displayed on a display based on the selection period; and output the selected images.

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 video endoscope including: an outer cladding tube, a fiber tube accommodated in the outer cladding tube, wherein the fiber tube has a housing bounding a closed space with a distal end and a proximal end, wherein a front-side window is provided at the distal end of the fiber tube, the fiber tube having an inner tube (for accommodating an imaging sensor , and a heating foil provided between the fiber tube and the inner tube. Where, the heating foil is adapted to heat the front-side window at the distal end of the fiber tube.
