  • Publication number: 20220110505
    Abstract: An information processing apparatus (2000) detects an abnormal region (30) in each of a plurality of video frames (14) constituting video data (12) in which the inside of a body is captured. The information processing apparatus (2000) outputs output information related to the detected abnormal region (30). Herein, the information processing apparatus (2000) starts outputting of the output information when a detection score based on a proportion of the number of the video frames (14) in which the abnormal region (30) is detected becomes equal to or more than a first threshold value in a state where outputting of the output information is not being performed. Further, the information processing apparatus (2000) ends outputting of the output information when the detection score becomes equal to or less than a second threshold value in a state where outputting of the output information is being performed.

  • Patent number: 11120554
    Abstract: An image diagnosis apparatus (10) performs a diagnosis assistance process using images (moving image) generated by an endoscope or the like. The image diagnosis apparatus (10) includes a first processing unit (110) and a second processing unit (120). The first processing unit (110) executes preprocessing of deciding whether or not a tumor judgment process is necessary with respect to each of a plurality of input images. The second processing unit (120) performs the tumor judgment process with respect to the input image for which it is decided that “the tumor judgment process is necessary” in the preprocessing executed by the first processing unit (110).
