Operation support system

An operation support system comprising:

• a display mounted in a watercraft;
• and
• a processor configured to:
• cause a first view to be displayed on the display, the first view being an oblique view of an image of the vicinity of the watercraft,
• cause a second view to be displayed on the display, the second view being of top view of an image of the vicinity of the watercraft of an angle different from that of the first view,
• superimpose a first object simulating the watercraft and a plurality of line-shaped second objects disposed in the vicinity of the first object onto the second view, the plurality of line-shaped second objects being respectively disposed at each of divided areas on an outer edge of the first object,
• superimpose a third object representing a positional relation between an obstacle in the vicinity of the watercraft and the watercraft onto the first view, the third object being an object having a first type indicating a first distance and a second type indicating a second distance which is shorter than the first distance,
• cause a type of display at least at the time of displaying the plurality of line-shaped second objects to be different depending on whether the positional relation satisfies predetermined conditions or the positional relation does not satisfy the predetermined conditions,
• determine whether each of the each of divided areas satisfies the predetermined conditions,
• superimpose the plurality of line-shaped second objects of the second type, onto the second view, in a case in which a first condition is satisfied, the first condition being a condition where a relative distance between the watercraft and the obstacle is the second distance, and
• superimpose the plurality of line-shaped second objects of the first type, onto the second view, in a case in which the first condition is not satisfied.
