The system is configured to: (i) analyze the signal(s); (ii) detect the size of the cervix; (iii) determine parameters defining properties of the cervix; (iv) determine and distinguish normal tissue from abnormal tissue within the cervix; (v) determine the location of area(s) of abnormal tissue in the cervix; and (vi) generate a panoramic view of the cervix.

A medical signal processing device includes: an acquisition unit is configured to acquire a first image signal acquired by emission of first light onto an object, and a second image signal acquired by emission of second light onto the object, the first light being in a wavelength band including visible light, and the second light exciting a fluorescent substance included in the object; a detection unit configured to detect each of a signal level of the visible light included in the first image signal and a signal level of fluorescence included in the second image signal; and a calculation unit configured to calculate a correction coefficient to correct the signal level of the fluorescence by using a result of the detection by the detection unit.

Endoscopic camera head devices and methods are provided using light captured by an endoscope system. Substantially afocal light from the endoscope is manipulated and split. After passing through focusing optics, another beamsplitter is used to split the light again, this time in image space, producing four portions of light that may be further manipulated. The four portions of light are focused onto separate areas of two image sensors. The manipulation of the beams can take several forms, each offering distinct advantages over existing systems when individually displayed, analyzed and/or combined by an image processor.

A medical support arm includes: a support arm that supports an endoscope; an actuator that drives the support arm; a measurement unit that measures a load applied to the actuator; a generation unit that generates three-dimensional information in a body into which the endoscope is inserted; and a correction unit that corrects the three-dimensional information on a basis of the measured load.

An image processing apparatus includes a processor including hardware, the processor being configured to: determine whether or not an overlapping portion is present in imaging areas included in a plurality of images captured by a plurality of imagers, respectively, the plurality of imagers being are inserted into a subject to capture images of an observation target at different positions from each other; determine whether or not each of the plurality of imagers is inserted to a focal point position at which the observation target is in focus; and generate a composite image that is composed of the plurality of images when it is determined that each of the plurality of imagers is inserted to the focal point position and that the overlapping portion is present in the imaging areas.

Scopes such as medical imaging camera head devices and methods are provided using light captured by an endoscope system or other medical scope or borescope. At least one polarizing optical element manipulates the polarization properties of image light. The manipulated image light is focused on an image sensor including polarizers for each pixel. Multiple images are produced based sets of pixels having the same orientation of polarizer. The resulting images are combined with high dynamic range techniques.

For example, using at least one light source first arrangement, it is possible to provide pulses of light to at least one portion of a biological structure. At least one detector second arrangement can be used to detect images from the portion(s) based on the pulses, and provide data based on the detection. With at least one configuration, it is possible prevent and/or reduce a movement of the apparatus within at least one anatomical body (i) is a particular surface of the apparatus, (ii) covers at least one portion of the surface, and/or (iii) extends from the surface. In addition or alternatively, with at least one computer third arrangement, it is possible to receive the data, and control a timing of at least one of activation or deactivation of at least one portion of the first arrangement based on the data.

An endoscopic imaging system for use in a light deficient environment includes an imaging device having a tube, one or more image sensors, and a lens assembly including at least one optical elements that corresponds to the one or more image sensors. The endoscopic system includes a display for a user to visualize a scene and an image signal processing controller. The endoscopic system includes a light engine having an illumination source generating one or more pulses of electromagnetic radiation and a lumen transmitting one or more pulses of electromagnetic radiation to a distal tip of an endoscope.
