Abstract: An endoscopic device generates an endoscopic image based on an image pickup signal generated by an image pickup device at a distal-end portion of an insertion portion, acquires channel information regarding a channel formed in the insertion portion, acquires angle information regarding a display angle of the endoscopic image, and generates and outputs a display image including a display endoscopic image generated based on modifying the endoscopic image based on the angle information, and a channel guide image generated based on the angle information and the channel information.

Abstract: An endoscope system includes an endoscope including at least one switch, each of which can be assigned two functions, and a controller. The controller sets a plurality of function pairs, each of which is composed of a combination of any one of a plurality of first functions and any one of a plurality of second functions, and assigns one function pair selected from the plurality of function pairs to the switch, measures a switch pressing time period after the switch is pressed, and executes the first function when the switch pressing is released before a predetermined first time period elapses after the switch is pressed and executes the second function when the switch pressing time period passes the first time period.
