1.35<A   (1)

1<L.sub.H/L.sub.V   (2)

1.5<(r.sub.V−L.sub.V)/(r.sub.H−L.sub.H)≦3.17   (3) where, A denotes a value calculated by the following expression when an aspect ratio long side:short side of an area of the image pickup element corresponding to a display image range is let to be H:V

A=H/V, L.sub.H denotes a dimension corresponding to the first direction of an end surface on an illumination lens side of the light guide, L.sub.V denotes a dimension corresponding to the second direction of the end surface on the illumination lens side of the light guide, r.sub.H denotes an outer-diameter dimension corresponding to the first direction of the illumination lens, and r.sub.V denotes an outer-diameter dimension corresponding to the second direction of the illumination lens.

An endoscope device having one or more processors configured to perform a control process including: processing an imaging signal to generate image data of a display image of a subject, wherein the image signal is generated by an image sensor, wherein the image sensor is arranged at a distal end of an insertion portion, and wherein a bending actuator is configured to bend the distal end; setting a first measurement point and a second measurement point on the display image; calculating a first subject distance from the first measurement point to a reference point of the image sensor, and a second subject distance from the second measurement point to the reference point; calculating a difference value between the first subject distance and the second subject distance; and controlling the bending actuator to bend the distal end of the insertion portion such that the difference value is decreased.

In some embodiments, a camera skid is presented. The camera skid includes a body into which a camera can be inserted; and a front portion received into the body, the front portion including a lip that contacts a face of the camera.

An adapter for use with an endoscope. The adapter including: at least first and second axis-shifted lenses, each of the first and second axis-shifted lenses including a truncated portion, the first and second axis shifted lenses being arranged side by side so that respective first and second optical axes are parallel to each other; and a prism arranged further distally than the first and second axis-shifted lenses, the prism being configured to change a viewing direction of each of the first and second axis-shifted lenses; wherein at least a portion of each of the truncated portions of the first and second axis-shifted lenses is arranged further outward in the radial direction than the prism.

The present disclosure relates to an endoscopy system. The endoscope system includes: a first light source unit configured to be provided on a substrate, and to have a first terminal to which power is supplied; a second light source configured to be provided on the substrate, and to have a second terminal to which power is supplied; a light guide unit configured to guide a light of the first light source unit and the second light source unit to the inside of a target object; an image sensing unit configured to sense the light reflected and reached from the target object to convert into an image signal; and an image signal processing unit configured to process the image signal to display on a display unit.

Provided is a capsule endoscope that includes a light source configured to emit light to an internal surface of an organ of a human body, an image sensor configured to use light reflected from the internal surface of the organ to generate image data, a processor configured to perform coding on the image data to generate coded data, and perform logical operation on the coded data and a binary code to generate final data, and a communication circuit configured to output the final data to an outside of the human body.

A device comprises a cannula having a first end, a second end, and a channel between the first end and the second end; an imaging probe couplable to the first end of the cannula, where the imaging probe includes: a transducer, and a reflective surface; and a biopsy device coupled to the cannula, where the biopsy device is configured to collect a tissue sample from an organ of a patient.

A video imaging system is provided. The video imaging system is configured to maintain a video image displayed on a display unit in a predetermined orientation based upon a use. The video imaging system includes an endoscope, a camera head unit, a camera control unit configured to determine a focal distance, and a display control unit. The display control unit is configured to process the focal distance to determine a use. The use is processed by the display control unit so as to maintain the video image in the predetermined orientation. The contextual information may be focal distance, image data or endoscopic orientation.

An image sensor includes: light receiving units disposed two-dimensionally on a substrate; color filters disposed on the light receiving units and including at least one of: a blue color filter for passing both of blue light and blue-violet light; a cyan color filter for passing both of green light and the blue-violet light; and a magenta color filter for passing both of red light and the blue-violet light; a first film arranged on a light receiving unit on which the cyan color filter is disposed, among the light receiving units, the first film having a peak of reflectivity near 450 nm; and a second film arranged on a light receiving unit on which the magenta color filter is disposed, among the light receiving units, the second film having a peak of reflectivity between 450 nm and 500 nm.
