摘要： A method of enhancing the visibility of blood vessels in a colour image captured by an image capturing device of a medical device, including, for at least some of the pixels of the image, the steps of: (a) processing data obtained from a first colour channel together with data obtained from a second colour channel to determine a value of a first parameter indicative of the intensity in the red spectrum relative to the total intensity of said pixel; (b) using said value of said first parameter and a first value of a user parameter to alter said pixel, the first value of the user parameter being based on user input, and wherein the strength of the alteration is dependent on both the value of said first parameter and the first value of said user parameter.

摘要： Provided is a medical image processing system capable of maintaining or improving the resolution of an image obtained by using narrow-band light of a short wavelength while maintaining image quality of an image obtained by using broadband light such as white light. A light source unit emits specific narrow-band light of a short wavelength. An image sensor includes a first pixel group including a B pixel and a second pixel group including a G pixel and a W pixel. The B pixel has a higher sensitivity to the specific narrow-band light than the G pixel. The G pixel has a sensitivity to light in a green band and the specific narrow-band light. The W pixel has a sensitivity to broadband illumination light including the light in the green band and the specific narrow-band light.

摘要： An apparatus, system and process for identifying one or more different tissue types are described. The method may include applying a configuration to one or more programmable light sources of an imaging system, where the configuration is obtained from a machine learning model trained to distinguish between the one or more different tissue types captured in image data. The method may also include illuminating a scene with the configured one or more programmable light sources, and capturing image data that includes one or more types of tissue depicted in the image data. Furthermore, the method may include analyzing color information in the captured image data with the machine learning model to identify at least one of the one or more different tissue types in the image data, and rendering a visualization of the scene from the captured image data that visually differentiates tissue types in the visualization.

摘要： In an endoscope system, an oxygen-saturation-level calculating unit calculates an oxygen saturation level of the observation target on the basis of a plurality of spectral images acquired by an image acquiring unit. An image creating unit creates an oxygen-saturation-level image that is an image representing the oxygen saturation level. A numerical-value display-position determining unit determines a numerical-value display position for displaying a numerical value of the oxygen saturation level on the oxygen-saturation-level image, on the basis of the spectral images or the oxygen saturation level, or the spectral images and the oxygen saturation level. A display control unit displays the numerical value of the oxygen saturation level on the oxygen-saturation-level image on the basis of the numerical-value display position.
