A system for determining the shape of a surgical instrument includes an elongate instrument body having a selectively steerable distal tip, a pair of automatically controlled segments proximal to the selectively steerable distal tip, and a joint that couples the pair of adjacent automatically controlled segments together. An actuator changes an angle of the joint and a position encoder provides information associated with the joint angle. A controller receives the information associated with the angle of the joint and generates a three dimensional model of a shape of the instrument. A method for determining the three dimensional shape of an instrument includes providing axial position data to a controller, providing angular position data to the controller from a respective segment controller, and generating a three-dimensional model of a shape of said instrument using the axial position data and the angular position data.

An imaging device includes an image sensor. The image sensor includes: a light receiving unit having pixels configured to receive light and generate an imaging signal according to an amount of the received light; a color filter having a filter unit disposed corresponding to the pixels, the filter unit including first band filters for passing light of a wavelength band of a primary color or a complementary color and including at least one second band filter for passing narrow-band light whose wavelength band is narrower than the wavelength band of the light passing through each of the first band filters; and an output unit configured to output the imaging signal under conditions that an amount of light incident on a second pixel corresponding to the at least one second band filter is greater than an amount of light incident on each of first pixels corresponding to the first band filters.

An embodiment in accordance with the present invention provides a method for accurate and objective quantification of stone fragment size. The method includes intraoperative measurement of objects during URS. The method analyzes URS procedures for ureteral and renal stones during basket extraction of fragments. An instrument is passed through an instrument channel of the ureteroscope and advanced until it is adjacent to the stone fragment to be measured. The measurement of stone fragment size is based on the known distance of a tip of the instrument in the ureteroscope's visual field.

An image capture device includes a plurality of stacked ceramic circuit boards, an image sensor, signal conditioning electronics, and a connector. Each ceramic circuit board is parallel and directly coupled to at least one other circuit board. The image sensor is mounted to a first ceramic circuit board. The signal conditioning electronics are mounted to one or more of the stacked ceramic circuit boards and are coupled to receive electrical signals generated by the image sensor. The image capture device is enclosed by a shaft and the stacked ceramic circuit boards are stacked along a length of the shaft. The connector is mounted to a second ceramic circuit board that is on an opposite side of the plurality of stacked ceramic circuit boards from the first ceramic circuit board. The connector is mounted to a side of the second ceramic circuit board facing away from the first ceramic circuit board.

The invention provides an image color enhancement system, method, storage medium and endoscope. Since the human skin color and the basic tone of endoscopic image are similar, a data set of Macbeth color card is utilized to generate a color correction matrix for skin color enhancement. The color correction matrix is used by an endoscope for real time image capture, resulting in a vivid expression of the basic tone of an endoscopic image without introducing artifacts in other tonal image parts.

An image processing apparatus includes a processor including hardware. The processor is configured to: execute a first white balance adjustment on a first signal corresponding to multiple wavelength bands; generate a luminance signal from a second signal including an area having saturation caused by the first white balance adjustment; extract a detail component based on the first signal; and apply the detail component to the luminance signal to generate a corrected luminance signal.
