An optically powered system for rapid, focused heating and melting of water ice. The optical wavelength is chosen to fall in a range where transmissivity through liquid water is higher than through ice. An alternative embodiment of the invention further comprises a length of fiber optic tether between source and output to allow for motion of the melt head. A further embodiment includes probing the ice using various sensing modalities exploiting the presence of the fiber in the ice, searching for biomarkers and characterizing the radiation/light environment for subsurface habitability, including photosynthetic potential and radiation environment as a source for energy.

Embodiments of the invention include an apparatus including at least one illumination source configured to emit illumination energy and an illumination control system to receive the illumination energy. The illumination control system is configured to control the illumination energy to output a sequence of different illumination wavelengths using the illumination energy. The apparatus also includes a plurality of optical fibers connected to the illumination control system and configured to sequentially output the different illumination wavelengths. Each optical fiber is configured to transmit a different illumination wavelength of the sequence to output the sequence of different illumination wavelengths from the optical fibers toward an object. The apparatus further includes an image capture device including a plurality of pixels, and each pixel of the image capture device is configured to detect the illumination energy associated with each of the plurality of different illumination wavelengths reflected from the object.

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.

[Object] It is desirable to provide a technology capable of further appropriately adjusting the luminance of the endoscopic image.

[Solution] Provided is an image processing device including: a peak detection unit configured to detect a first peak and a second peak in sequence from a high luminance side from a number-of-pixel distribution for each luminance of an endoscopic image based on imaging by an image sensor; and an exposure control unit configured to perform exposure control on a basis of a first luminance difference between the first peak and the second peak.

The invention provides medical or industrial light source devices, for example, an endoscope.

A light source device includes: a light source emitting a light beam; a concentrator including a pair of Fresnel lenses with corrugated surfaces and concentrating the emitted light beam, the corrugated surfaces of the Fresnel lenses facing each other, and a light guide guiding the concentrated light beam.

The corrugated surfaces of the pair of Fresnel lenses may be in contact with each other and one end of the light guide may be disposed at a focal point of the concentrated light beam.

There are provided an endoscopic diagnosis apparatus, image processing method, and recording medium that enable easy measurement of the size of a lesion portion or the like based on an endoscopic image captured through a normal operation without a special operation. A region detecting unit detects, from an endoscopic image, a region of an artificial object or the like that is in contact with a subject. An imaging size calculating unit calculates, in number of pixels, an imaging size in the endoscopic image of the region of the artificial object or the like that is in contact with the subject. A pixel size calculating unit calculates an actual size corresponding to one pixel. A scale generating unit generates scales indicating an actual size of the subject in the endoscopic image. A control unit performs control to combine the endoscopic image and the scales and to display.

There are provided an endoscopic diagnosis apparatus, image processing method, and a non-transitory computer-readable recording medium that enable easy measurement of the size of a lesion portion or the like based on an endoscopic image captured through a normal operation without a special operation. A region detecting unit detects, from a position in an endoscopic image, a region having a periodic structure of living tissue. An imaging size calculating unit calculates, in number of pixels, an imaging size in the endoscopic image equivalent to a period in the periodic structure in the region having the periodic structure. A pixel size calculating unit calculates an actual size corresponding to one pixel of the endoscopic image. A scale generating unit generates scales indicating an actual size of the subject in the endoscopic image. A control unit causes the endoscopic image and the scales to be combined and displayed on a display unit.

The present invention relates to a method for producing adaptive lighting controls for an endoscope with multiple light emitting elements such as distinct light fibers, or distinct distal light emitting diodes (LEDs), etc. The amount of light delivered to the scene can be locally adjusted on a per-light basis to manage the dynamic range of the scene. For example highly reflective metallic tools many benefit from reduced light, while cavities may benefit from increased light projected into the lumen.

A light source apparatus includes an optical illumination unit that converts optical characteristics of primary light emitted from a light source unit and emits secondary light different from the primary light; and an adapter unit that outwardly emits illumination light generated based on the secondary light emitted from the optical illumination unit and that is attachable to/detachable from the optical illumination unit. A radiation angle control member converts a traveling direction of the secondary light so that the secondary light allowed to emit from a light conversion member toward the radiation angle control member in the secondary light allowed to emit from the light conversion member travels toward the adapter unit through the secondary light emit portion.
