  • Publication number: 20240046599
    Abstract: An endoscope processor includes a processor. The processor detects a first region of a lesion candidate from first image information which is acquired by irradiation with first illumination light; detects a second region of a lesion candidate from second image information acquired by irradiation with second illumination light having a different spectrum from the first illumination light; selects a region for display of the lesion candidate out of the first region and the second region, corresponding to an observation target site of a subject; and generates image information for display, in which the region for display is superimposed on the first image information.

  • Patent number: 11642005
    Abstract: A processor of an endoscope system detects from the observation images a lesion area which is an observation target of the endoscope, judges a level of an oversight risk which is a risk that an operator may overlook the lesion area, on the basis of the observation images, and controls notification methods of detection of the lesion area on the basis of the level of the oversight risk. The processor displays the marker image indicating the lesion area only in a second image region of the display apparatus when a level of the oversight risk relating to the lesion area is a first level and displays the marker image in both a first image region and the second image region which is smaller than the first image region when a level of the oversight risk relating to the lesion area is a second level higher than the first level.

  • Publication number: 20230007213
    Abstract: An image recording system includes a processor. The processor acquires a time series RAW image group including a plurality of time series RAW images in a first time section. The processor extracts, from the time series RAW image group, a recording candidate RAW image group included in a second time section as a part of the first time section. The processor records at least one RAW image included in the recording candidate RAW image group as a recording target RAW image which is a RAW image to be recorded. The processor selects the recording target RAW image from the recording candidate RAW image group. The processor converts the RAW image which is not selected as the recording target RAW image from the recording candidate RAW image group or the time series RAW image group to compressed data, and records the compressed data.

  • Publication number: 20220375089
    Abstract: An endoscope apparatus includes a processor. The processor conducts analysis whether an endoscope image has been appropriately captured or not on the basis of the endoscope image. The processor acquires correction restriction information that is at least one of a restriction regarding a size of a lumen of an image-captured portion or a restriction regarding a submucosa state of the image-captured portion. The processor generates correction information regarding correction of image-capturing conditions for allowing the endoscope image to be appropriately captured under a restriction of the correction restriction information in a case where it is analyzed that the endoscope image has not been appropriately captured, and outputs the correction information on a monitor.

  • Publication number: 20190090778
    Abstract: A capsule endoscope position detection method includes first to third steps. The method uses at least four antennas configured to receive signals wirelessly transmitted from a capsule endoscope inside a subject. In the first step, a calculation device calculates a distance difference between a first distance and a second distance on the basis of the signals received by two of the at least four antennas. The first distance is a distance between one of the two antennas and a capsule endoscope. The second distance is a distance between the other of the two antennas and the capsule endoscope. In the second step, the calculation device selects at least three distance differences among the distance differences calculated in the first step. In the third step, the calculation device calculates a Z coordinate of the capsule endoscope on the basis of the selected distance difference.
