  • Publication number: 20230419517
    Abstract: A display processing unit causes a display device to display an endoscopic image of a living tissue in a somatic cavity captured by an endoscope. An operation reception unit receives a user operation that is performed so as to set an area of interest in the endoscopic image. An area-of-interest setting unit sets the area of interest in the endoscopic image based on the user operation. A three-dimensional information acquisition unit acquires three-dimensional shape information of the living tissue captured by the endoscope. A virtual surface derivation unit derives three-dimensional shape information of a virtual surface in the area of interest from three-dimensional shape information of an area different from the area of interest. A size information identification unit identifies information concerning a size of the virtual surface from the three-dimensional shape information of the virtual surface.

  • Publication number: 20230382374
    Abstract: A traveling control apparatus includes a speed control processor, first and second brake command detectors, a brake control processor, and an operational state setting unit. The speed control processor controls a vehicle speed to cause a vehicle to travel at a target speed, and is switchable between an active operational state and an inactive operational state. The first brake command detector detects a first brake command based on a driver's operation. The brake control processor generates a second brake command based on an environment outside the vehicle. The second brake command detector detects the second brake command. The operational state setting unit maintains the speed control processor in the active operational state when the first brake command is generated while the speed control processor is in the active operational state, and switches the speed control processor to the inactive operational state when the second brake command is generated.
