Endoscopic device, display image output method, computer-readable medium, and endoscopic system

A display image output method comprising:

• generating an endoscopic image;
• acquiring channel information regarding each of at least two channels formed in an insertion portion of an endoscope;
• acquiring angle information regarding a display angle of the endoscopic image;
• generating a display endoscopic image by modifying the endoscopic image based on the angle information;
• generate a channel guide image separate from the endoscopic image based on both the angle information and the channel information;
• and
• generating and outputting a display image including both the display endoscopic image and the channel guide image,
• wherein the channel information includes information regarding angles of positions of channel outlets of respective ones of the two channels or of the channel guide image when the display angle of the endoscopic image is 0°, and/or information regarding angles of positions of the channel outlets or of the channel guide image when the display angle of the endoscopic image is 180°.

A non-transitory computer-readable storage medium storing a computer executable program for causing a computer to perform processing comprising:

• generating an endoscopic image;
• acquiring channel information regarding each of at least two channels formed in an insertion portion of an endoscope;
• acquiring angle information regarding a display angle of the endoscopic image;
• generating a display endoscopic image by modifying the endoscopic image based on the angle information;
• generate a channel guide image separate from the endoscopic image based on both the angle information and the channel information;
• and
• generating and outputting a display image including a-both the display endoscopic image and the channel guide image,
• wherein the channel information includes information regarding angles of positions of channel outlets of respective ones of the two channels or of the channel guide image when the display angle of the endoscopic image is 0°, and/or information regarding angles of positions of the channel outlets or of the channel guide image when the display angle of the endoscopic image is 180°.

An endoscopic system comprising:

• an endoscope including:
• an insertion portion;
• an image pickup device at a distal-end portion of the insertion portion;
• at least two channels formed in the insertion portion;
• and
• a memory storing channel information regarding the channels, and
• an endoscopic device including a processor configured to:
• generate an endoscopic image;
• acquire channel information regarding each of at least two channels formed in an insertion portion of an endoscope;
• acquire angle information regarding a display angle of the endoscopic image;
• generate a display endoscopic image by modifying the endoscopic image based on the angle information;
• generate a channel guide image separate from the endoscopic image based on both the angle information and the channel information;
• and
• generate and output a display image including both the display endoscopic and the channel guide image,
• wherein the channel information includes information regarding angles of positions of channel outlets of respective ones of the two channels or of the channel guide image when the display angle of the endoscopic image is 0°, and/or information regarding angles of positions of the channel outlets or of the channel guide image when the display angle of the endoscopic image is 180°.
