  • Patent number: 11176665
    Abstract: An endoscopic image processing device includes one or more processors. The processors perform: detecting a region of interest for an observation image, the observation image being obtained by picking up an image of an object and being sequentially input to the processors, judging whether detection of the region of interest continues or not to acquire a judgment result, emphasizing with adding visual information for emphasizing a position of the region of interest to the observation image during a period during which the region of interest is detected. The processors cause an appearance of the visual information added to the observation image to differ between a case where the detection of the region of interest continues for a predetermined time period or more and a case where the detection of the region of interest discontinues in a time period shorter than the predetermined time period, based on the judgment result.

  • Patent number: 10893792
    Abstract: An endoscope image processing apparatus includes a region-of-interest detection apparatus configured to sequentially receive observation images obtained by performing image pickup of an object and perform processing for detecting a region of interest for each of the observation images, and a processor. The processor calculates an appearance time period as an elapsed time period from a time when the region of interest appears within the observation image when the region-of-interest detection apparatus detects the region of interest, and starts emphasis processing for emphasizing a position of the region of interest existing within the observation image at a timing at which the appearance time period reaches a predetermined time period.
