  • Patent number: 11766167
    Abstract: An image processing apparatus includes a special light image acquisition unit that acquires a special light image having information in a specific wavelength band, a generation unit that generates depth information at a predetermined position in a living body using the special light image, and a detection unit that detects a predetermined region using the depth information. The image processing apparatus further includes a normal light image acquisition unit that acquires a normal light image having information in a wavelength band of white light. The specific wavelength band is, for example, infrared light. The generation unit calculates a difference in a depth direction between the special light image and the normal light image to generate depth information at the predetermined position. The detection unit detects a position in which the depth information is a predetermined threshold or more as a bleeding point. The present technology is applicable to an endoscope.

  • Publication number: 20220183576
    Abstract: A medical system (1) acquires a speckle image from an imaging means that images reflected light of coherent light from a subject. Furthermore, a first parameter value and a second parameter value different from each other are stored as a parameter for calculating a speckle index value that is a statistical index value for a luminance value of a speckle. Furthermore, in a case where a first mode is selected, the speckle index value is calculated on the basis of the speckle image and the first parameter value, and in a case where a second mode is selected, the speckle index value is calculated on the basis of the speckle image and the second parameter value. Then, a speckle index value image is generated on the basis of the calculated speckle index value and displayed on a display unit (74).

  • Patent number: 11216941
    Abstract: The present technology relates to a medical image processing apparatus, a medical image processing method, and a program that permit superimposition of images at an appropriate mixing ratio without deletion of detailed information. An acquisition section, a superimposition ratio calculation section, and a superimposition processing section are included. The acquisition section acquires a normal frame captured with normal light irradiated on a subject and a special frame captured with special light irradiated on the subject. The superimposition ratio calculation section calculates, on the basis of an intensity value of the special frame, a superimposition ratio indicating a ratio at which the normal frame and the special frame are superimposed. The superimposition processing section performs a superimposition process of superimposing the normal frame and the special frame on the basis of the superimposition ratio. The present technology is applicable to an image processing apparatus for medical use.
