  • Publication number: 20210106208
    Abstract: An endoscopic image processing apparatus includes an image acquiring unit, a region-of-interest detection unit, a detection cessation determination unit, a display determination unit, and a display output unit. The detection cessation determination unit determines whether a detection of a region of interest in the region-of-interest detection unit has ceased. The display determination unit performs a display propriety determination as a determination of whether to display assisting information on a display unit, when a cessation determination is acquired in the detection cessation determination unit. The assisting information is information for assisting the region of interest, the detection of which has ceased, to be restored on a screen of a display unit.

  • 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.

  • Publication number: 20200058124
    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: 10259680
    Abstract: A cable system A includes a cable 3 for connecting a base device 1 and a travelling body 2, a reel device 10 mounted on the travelling body 2, a motor controller 40 for controlling a motor 15 of the reel device 10, and a rotary encoder 16 (rotation sensor) for detecting rotation of a reel 12. The motor controller 40 basically makes the motor 15 free, when the reel 12 is rotating in an unreeling direction, and basically applies a rotational torque in a reeling direction to the reel 12, when the reel 12 is rotating in the reeling direction. Furthermore, even if the reel 12 is rotating in the unreeling direction, if an unreeling speed of the cable 3 exceeds a travelling speed of the travelling body 2, the rotational torque in the reeling direction is applied to the reel 12. Slackening of the cable 3 is thereby prevented.
